Intimate Partner Violence in Gay Men

QUESTION: how does intimate partner violence (IPV) affect the health of homeosexual men?

METHODS: a database review was performed.

RESULTS:
  • For victims, exposure to IPV was associated with increased odds of substance use, being HIV positive, reporting depressive symptoms, and engagement in unprotected anal sex.
  • For perpetrators, IPV was associated with increased odds of substance use. 
 CONCLUSIONS: victims of IPV among gay men have significant associated adverse health issues, which are greater in magnitude than that observed by the perpetrators.

Muscle-strengthening and conditioning activities and risk of type 2 diabetes: a prospective study in two cohorts of US women.

BACKGROUND: aerobic physical activity lowers the risk of type 2 diabetes. Do muscle-strengthening activities lower the risk as well?


METHODS: 99,316 women were followed-up for 8 years from the Nurses' Health Study ([NHS] aged 53-81 years, 2000-2008) and Nurses' Health Study II ([NHSII] aged 36-55 years, 2001-2009). The women were free of diabetes, cancer, and cardiovascular diseases at baseline.

RESULTS: the pooled relative risk (RR) for T2D for women performing 1-29, 30-59, 60-150, and >150 min/week of total muscle-strengthening and conditioning activities was 0.83, 0.93, 0.75, and 0.60 compared to women reporting no muscle-strengthening and conditioning activities (p<0.001 for trend). Women who engaged in at least 150 min/week of aerobic MVPA and at least 60 min/week of muscle-strengthening activities had substantial risk reduction compared with inactive women (pooled RR = 0.33).

CONCLUSIONS: muscle-strengthening and conditioning activities are associated with a lower risk of developing type 2 diabetes mellitus.

Point-of-care ultrasonography in dyspnea

OBJECTIVES:

Is point-of-care (POC) lungultrasound (US) diagnostically useful in patients with suspected acute cardiogenic pulmonary edema (ACPE) ?

METHODS:

A systematic review was done. Studies of asymptomaticindividuals or in patients where there was no suspicion of ACPE wereexcluded. The outcome of interest was a diagnosis of ACPE using US
B-lines. A final diagnosis from clinical follow-up was accepted as the reference standard.

RESULTS:

Seven articles (n = 1,075) were identified. The sensitivity of point-of-care US using B-lines to diagnosis ACPE is 94.1% (95% confidence interval [CI] = 81.3% to 98.3%) and the specificity is 92.4% (95% CI = 84.2% to 96.4%).

CONCLUSIONS:

This study suggests that an US study showing B-lines can be used to strengthen an emergency physician's working diagnosis of ACPE.

Withdrawal of inhaled glucocorticoids and exacerbations of COPD.


Withdrawal of inhaled glucocorticoids and exacerbations of COPD.
BACKGROUND: Treatment with inhaled glucocorticoids in combination with long-acting bronchodilators is recommended in patients with frequent exacerbations of severe chronic obstructive pulmonary disease (COPD). However, the benefit of inhaled glucocorticoids in addition to two long-acting bronchodilators has not been fully explored.
 
METHODS: In this 12-month, double-blind, parallel-group study, 2485 patients with a history of exacerbation of COPD received triple therapy consisting of tiotropium (at a dose of 18 μg once daily), salmeterol (50 μg twice daily), and the inhaled glucocorticoid fluticasone propionate (500 μg twice daily) during a 6-week run-in period. Patients were then randomly assigned to continued triple therapy or withdrawal of fluticasone in three steps over a 12-week period. The primary end point was the time to the first moderate or severe COPD exacerbation. Spirometric findings, health status, and dyspnea were also monitored.
RESULTS: As compared with continued glucocorticoid use, glucocorticoid withdrawal met the prespecified noninferiority criterion of 1.20 for the upper limit of the 95% confidence interval (CI) with respect to the first moderate or severe COPD exacerbation (hazard ratio, 1.06; 95% CI, 0.94 to 1.19). At week 18, when glucocorticoid withdrawal was complete, the adjusted mean reduction from baseline in the trough forced expiratory volume in 1 second was 38 ml greater in the glucocorticoid-withdrawal group than in the glucocorticoid-continuation group (P<0.001); a similar between-group difference (43 ml) was seen at week 52 (P=0.001). No change in dyspnea and minor changes in health status occurred in the glucocorticoid-withdrawal group.

 CONCLUSIONS: In patients with severe COPD receiving tiotropium plus salmeterol, the risk of moderate or severe exacerbations was similar among those who discontinued inhaled glucocorticoids and those who continued glucocorticoid therapy. However, there was a greater decrease in lung function during the final step of glucocorticoid withdrawal.

Age-adjusted D-dimer cutoff levels to rule out pulmonary embolism: the ADJUST-PE study.

Age-adjusted D-dimer cutoff levels to rule out pulmonary embolism: the ADJUST-PE study.
JAMA. 2014 Mar 19;311(11):1117-24
Authors: Righini M, Van Es J, Den Exter PL, Roy PM, Verschuren F, Ghuysen A, Rutschmann OT, Sanchez O, Jaffrelot M, Trinh-Duc A, Le Gall C, Moustafa F, Principe A, Van Houten AA, Ten Wolde M, Douma RA, Hazelaar G, Erkens PM, Van Kralingen KW, Grootenboers MJ, Durian MF, Cheung YW, Meyer G, Bounameaux H, Huisman MV, Kamphuisen PW, Le Gal G

D-dimer measurement is an important step in the diagnostic strategy of clinically suspected acute pulmonary embolism (PE), but its clinical usefulness is limited in elderly patients.

INTERVENTIONS: All consecutive outpatients who presented to the emergency department with clinically suspected PE were assessed by a sequential diagnostic strategy based on the clinical probability assessed using either the simplified, revised Geneva score or the 2-level Wells score for PE; highly sensitive D-dimer measurement; and computed tomography pulmonary angiography (CTPA). Patients with a D-dimer value between the conventional cutoff of 500 µg/L and their age-adjusted cutoff did not undergo CTPA and were left untreated and formally followed-up for a 3-month period.

RESULTS: Of the 3346 patients with suspected PE included, the prevalence of PE was 19%. Among the 2898 patients with a nonhigh or an unlikely clinical probability, 817 patients (28.2%) had a D-dimer level lower than 500 µg/L (95% CI, 26.6%-29.9%) and 337 patients (11.6%) had a D-dimer between 500 µg/L and their age-adjusted cutoff (95% CI, 10.5%-12.9%). The 3-month failure rate in patients with a D-dimer level higher than 500 µg/L but below the age-adjusted cutoff was 1 of 331 patients (0.3% [95% CI, 0.1%-1.7%]). Among the 766 patients 75 years or older, of whom 673 had a nonhigh clinical probability, using the age-adjusted cutoff instead of the 500 µg/L cutoff increased the proportion of patients in whom PE could be excluded on the basis of D-dimer from 43 of 673 patients (6.4% [95% CI, 4.8%-8.5%) to 200 of 673 patients (29.7% [95% CI, 26.4%-33.3%), without any additional false-negative findings.

CONCLUSIONS AND RELEVANCE: Compared with a fixed D-dimer cutoff of 500 µg/L, the combination of pretest clinical probability assessment with age-adjusted D-dimer cutoff was associated with a larger number of patients in whom PE could be considered ruled out with a low likelihood of subsequent clinical venous thromboembolism.

Mortality from ruptured abdominal aortic aneurysms: clinical lessons from a comparison of outcomes in England and the USA.

BACKGROUND: The outcome of patients with ruptured abdominal aortic aneurysm (rAAA) varies by country. Study of practice differences might allow the formulation of pathways to improve care.
METHODS: We compared data from the Hospital Episode Statistics for England and the Nationwide Inpatient Sample for the USA for patients admitted to hospital with rAAA from 2005 to 2010. Primary outcomes were in-hospital mortality, mortality after intervention, and decision to follow non-corrective treatment. In-hospital mortality and the rate of non-corrective treatment were analysed by binary logistic regression for each health-care system, after adjustment for age, sex, year, and Charlson comorbidity index.
FINDINGS: The study included 11,799 patients with rAAA in England and 23,838 patients with rAAA in the USA. In-hospital mortality was lower in the USA than in England (53·05% [95% CI 51·26-54·85] vs 65·90%; p<0·0001). Intervention (open or endovascular repair) was offered to a greater proportion of cases in the USA than in England (19,174 [80·43%] vs 6897 [58·45%]; p<0·0001) and endovascular repair was more common in the USA than in England (4003 [20·88%] vs 589 [8·54%]; p<0·0001). Postintervention mortality was similar in both countries (41·77% for England and 41·65% for USA). These observations persisted in age-matched and sex-matched comparisons. In both countries, reduced mortality was associated with increased use of endovascular repair, increased hospital caseload (volume) for rAAA, high hospital bed capacity, hospitals with teaching status, and admission on a weekday.
INTERPRETATION: In-hospital survival from rAAA, intervention rates, and uptake of endovascular repair are lower in England than in the USA. In England and the USA, the lowest mortality for rAAA was seen in teaching hospitals with larger bed capacities and doing a greater proportion of cases with endovascular repair. These common factors suggest strategies for improving outcomes for patients with rAAA.

Five-week outcomes from a dosing trial of therapeutic massage for chronic neck pain.

HYPOTHESIS: There is an optimal dose of massage that will benefit patients with neck pain.

METHODS: 228 individuals with chronic nonspecific neck pain were randomized into 5 groups receiving various doses of massage over a 4 week time frame: 30-minute visits 2 or 3 times weekly or 60-minute visits 1, 2, or 3 times weekly. There also was a single control group (a 4-week period on a wait list).

RESULTS: 30-minute treatments were not significantly better than placebo. 60-minute treatments 2 and 3 times weekly significantly increased the likelihood of improvement in terms of both neck dysfunction and pain intensity.

CONCLUSIONS: multiple 60-minute massages per week decreases neck dysfunction and pain intensity. 30 minute sessions are no more effective than placebo.

The 10 building blocks of high-performing primary care.

Our experiences studying exemplar primary care practices, and our work assisting other practices to become more patient centered, led to a formulation of the essential elements of primary care, which we call the 10 building blocks of high-performing primary care.
  1. leadership
  2. data-driven improvement
  3. empanelment
  4. team-based care
  5. patient-team partnership
  6. population management
  7. continuity of care
  8. prompt access to care
  9. comprehensiveness and care coordination
  10. a template of the future
The building blocks, which represent a synthesis of the innovative thinking that is transforming primary care in the United States, are both a description of existing high-performing practices and a model for improvement. Ann Fam Med. 2014 Mar-Apr;12(2):166-71

Prognosis of Mild Cognitive Impairment in General Practice: Results of the German AgeCoDe Study.

PURPOSE what is the prognosis of mild cognitive impairment?

METHODS 357 patients with MCI aged 75 years or older  with follow-up for 3 years.

RESULTS Overall, 41.5% of the patients had remission of symptoms with normal cognitive function 1.5 and 3 years later, 21.3% showed a fluctuating course, 14.8% had stable symptoms, and 22.4% had progression to dementia. Patients were at higher risk for advancing if they had symptoms of depression, impairment in more than 1 cognitive domain, or more severe cognitive impairment, or were older.

CONCLUSIONS In primary care, about one-quarter of patients with MCI progress to dementia within 3 years. Do not forget: three-quarters of patients with MCI stayed cognitively stable or even improved within 3 years.

Self-rated health and long-term prognosis of depression.

PURPOSE Indicators of prognosis should be considered to fully inform clinical decision making in the treatment of depression. This study examines whether self-rated health predicts long-term depression outcomes in primary care.  

METHODS Our analysis was based on the first 5 years of a prospective 10-year cohort study underway since January 2005 conducted in 30 randomly selected Australian primary care practices. Participants were 789 adult patients with a history of depressive symptoms. Main outcome measures include risks, risk differences, and risk ratios of major depressive syndrome (MDS) on the Patient Health Questionnaire.

RESULTS Retention rates during the 5 years were 660 (84%), 586 (74%), 560 (71%), 533 (68%), and 517 (66%). At baseline, MDS was present in 27% (95% CI, 23%-30%). Cross-sectional analysis of baseline data showed participants reporting poor or fair self-rated health had greater odds of chronic illness, MDS, and lower socioeconomic status than those reporting good to excellent self-rated health. For participants rating their health as poor to fair compared with those rating it good to excellent, risk ratios of MDS were 2.10 (95% CI, 1.60-2.76), 2.38 (95% CI, 1.77-3.20), 2.22 (95% CI, 1.70-2.89), 1.73 (95% CI, 1.30-2.28), and 2.15 (95% CI, 1.59-2.90) at 1, 2, 3, 4, and 5 years, after accounting for missing data using multiple imputation. After adjusting for age, sex, multimorbidity, and depression status and severity, self-rated health remained a predictor of MDS up to 5 years.  

CONCLUSIONS Self-rated health offers family physicians an efficient and simple way to identify patients at risk of poor long-term depression outcomes and to inform therapeutic decision making.

After Major Surgery, Who is at Risk for Prolonged Opiod Use?

This population based retrospective cohort study of acute care hospitals in Ontario, Canada looked at almost 40,000 opioid naive patients over age 65 who underwent major elective surgery. They looked at the outcome of prolonged opioid use after discharge. They found that 3.1% continued to receive opioids for more than 90 days after surgery. Factors associated with an increased risk of prolonged opioid use included:
  • younger age
  • lower household income
  • specific comorbidities (diabetes, heart failure, pulmonary disease)
  • preoperative use of  benzodiazepines, selective serotonin reuptake inhibitors, angiotensin converting enzyme inhibitors)
  • Thoracic procedures compared to open radical prostatectomies
On the flip side, open and minimally invasive major gynecological procedures were associated with significantly lower risks.

Live vaccine against measles, mumps, and rubella and the risk of hospital admissions for nontargeted infections.

Live vaccine against measles, mumps, and rubella and the risk of hospital admissions for nontargeted infections.
JAMA. 2014 Feb 26;311(8):826-35
Authors: Sørup S, Benn CS, Poulsen A, Krause TG, Aaby P, Ravn H

IMPORTANCE: In low-income countries, live measles vaccine reduces mortality from causes other than measles infection. Such nonspecific effects of vaccines might also be important for the health of children in high-income settings.
OBJECTIVE: To examine whether the live vaccine against measles, mumps, and rubella (MMR) is associated with lower rates of hospital admissions for infections among children in Denmark.
DESIGN, SETTING, AND PARTICIPANTS: Population-based cohort study of Danish children born 1997-2006 and followed up from ages 11 months to 2 years (last follow-up, August 31, 2008). Nationwide Danish registers provided data on vaccinations and hospital admissions. The recommended vaccination schedule was inactivated vaccine against diphtheria, tetanus, pertussis, polio, and Haemophilus influenzae type b (DTaP-IPV-Hib) administered at ages 3, 5, and 12 months and MMR at age 15 months.
MAIN OUTCOMES AND MEASURES: Incidence rate ratios (IRRs) of hospital admissions for any infection, comparing receipt of MMR vs DTaP-IPV-Hib as the most recent vaccine. Risks, risk difference, and number needed to vaccinate were calculated for receiving MMR on time.
RESULTS: The study included 495,987 children contributing with 56,889 hospital admissions for any type of infection during 509,427 person-years (rate, 11.2 per 100 person-years). For the 456,043 children who followed the recommended schedule and received MMR after the third dose of DTaP-IPV-Hib, MMR (rate, 8.9 per 100 person-years) vs the third dose of DTaP-IPV-Hib (rate, 12.4 per 100 person-years) as the most recent vaccine was associated with an adjusted IRR of 0.86 (95% CI, 0.84-0.88) for any admission for infection. There were 19,219 children immunized out of sequence. The adjusted IRR was 0.87 (95% CI, 0.80-0.95) for those receiving MMR (rate, 9.9 per 100 person-years) after the second dose of DTaP-IPV-Hib (rate, 15.1 per 100 person-years). However, in the 1981 children who subsequently received the third dose of DTaP-IPV-Hib (rate, 12.8 per 100 person-years) after MMR, the IRR for hospital admissions for infection was significantly greater (adjusted IRR, 1.62 [95% CI, 1.28-2.05]). The risk of admission for an infection between ages 16 months and 24 months was 4.6% (95% CI, 4.5%-4.7%) for receiving MMR on time and 5.1% (95% CI, 5.0%-5.2%) for not receiving MMR on time. The risk difference was 0.5 percentage point (95% CI, 0.4-0.6), and the number needed to vaccinate with MMR before age 16 months to prevent 1 admission for any infection was 201 (95% CI, 159-272).
CONCLUSIONS AND RELEVANCE: In a cohort of Danish children, receipt of live MMR vs inactivated DTaP-IPV-Hib as the most recent vaccine was associated with a lower rate of hospital admissions for any infections. These findings require replication in other high-income populations.

Patterns and outcomes of red blood cell transfusion in patients undergoing percutaneous coronary intervention.

Patterns and outcomes of red blood cell transfusion in patients undergoing percutaneous coronary intervention.
JAMA. 2014 Feb 26;311(8):836-43
Authors: Sherwood MW, Wang Y, Curtis JP, Peterson ED, Rao SV

IMPORTANCE: Studies have shown variation in the use of red blood cell transfusion among patients with acute coronary syndromes. There are no definitive data for the efficacy of transfusion in improving outcomes, and concerning data exist about possible association with harm. Current transfusion practices in patients undergoing percutaneous coronary intervention (PCI) are not well understood.
OBJECTIVE: To determine the current patterns of blood transfusion among patients undergoing PCI and the association of transfusion with adverse cardiac outcomes across hospitals in the United States.
DESIGN, SETTING, AND PARTICIPANTS: Retrospective cohort study of all patient visits from the CathPCI Registry from July 2009 to March 2013 that included PCI, excluding those with missing data on bleeding complications or who underwent in-hospital coronary artery bypass graft surgery (N = 2,258,711 visits).
MAIN OUTCOMES AND MEASURES: Transfusion rates in the overall population and by hospital (N = 1431) were the primary outcomes. The association of transfusion with myocardial infarction, stroke, and death after accounting for a patient's propensity for transfusion was also measured.
RESULTS: The overall rate of transfusion was 2.14% (95% CI, 2.13%-2.16%) and quarterly transfusion rates slightly declined from July 2009 to March 2013 (from 2.11% [95% CI, 2.03%-2.19%] to 2.04% [95% CI, 1.97%-2.12%]; P < .001). Patients who were more likely to receive transfusion were older (mean, 70.5 vs 64.6 years), were women (56.3% vs 32.5%), and had hypertension (86.4% vs 82.0%), diabetes (44.8% vs 34.6%), advanced renal dysfunction (8.7% vs 2.3%), prior myocardial infarction (33.0% vs 30.2%), or prior heart failure (27.0% vs 11.8%). Overall, 96.3% of sites gave a transfusion to less than 5% of patients and 3.7% of sites gave a transfusion to 5% of patients or more. Variation in hospital risk-standardized rates of transfusion persisted after adjustment, and hospitals showed variability in their transfusion thresholds. Receipt of transfusion was associated with myocardial infarction (42,803 events; 4.5% vs 1.8%; odds ratio [OR], 2.60; 95% CI, 2.57-2.63), stroke (5011 events; 2.0% vs 0.2%; OR, 7.72; 95% CI, 7.47-7.98), and in-hospital death (31,885 events; 12.5% vs 1.2%; OR, 4.63; 95% CI, 4.57-4.69), irrespective of bleeding complications.
CONCLUSIONS AND RELEVANCE: Among patients undergoing PCI at US hospitals, there was considerable variation in blood transfusion practices, and receipt of transfusion was associated with increased risk of in-hospital adverse cardiac events. These observational findings may warrant a randomized trial of transfusion strategies for patients undergoing PCI.

Twenty five year follow-up for breast cancer incidence and mortality of the Canadian National Breast Screening Study: randomised screening trial.

Twenty five year follow-up for breast cancer incidence and mortality of the Canadian National Breast Screening Study: randomised screening trial.
BMJ. 2014;348:g366
Authors: Miller AB, Wall C, Baines CJ, Sun P, To T, Narod SA

OBJECTIVE: To compare breast cancer incidence and mortality up to 25 years in women aged 40-59 who did or did not undergo mammography screening.
DESIGN: Follow-up of randomised screening trial by centre coordinators, the study's central office, and linkage to cancer registries and vital statistics databases.
SETTING: 15 screening centres in six Canadian provinces,1980-85 (Nova Scotia, Quebec, Ontario, Manitoba, Alberta, and British Columbia).
PARTICIPANTS: 89,835 women, aged 40-59, randomly assigned to mammography (five annual mammography screens) or control (no mammography).
INTERVENTIONS: Women aged 40-49 in the mammography arm and all women aged 50-59 in both arms received annual physical breast examinations. Women aged 40-49 in the control arm received a single examination followed by usual care in the community.
MAIN OUTCOME MEASURE: Deaths from breast cancer.
RESULTS: During the five year screening period, 666 invasive breast cancers were diagnosed in the mammography arm (n=44,925 participants) and 524 in the controls (n=44,910), and of these, 180 women in the mammography arm and 171 women in the control arm died of breast cancer during the 25 year follow-up period. The overall hazard ratio for death from breast cancer diagnosed during the screening period associated with mammography was 1.05 (95% confidence interval 0.85 to 1.30). The findings for women aged 40-49 and 50-59 were almost identical. During the entire study period, 3250 women in the mammography arm and 3133 in the control arm had a diagnosis of breast cancer, and 500 and 505, respectively, died of breast cancer. Thus the cumulative mortality from breast cancer was similar between women in the mammography arm and in the control arm (hazard ratio 0.99, 95% confidence interval 0.88 to 1.12). After 15 years of follow-up a residual excess of 106 cancers was observed in the mammography arm, attributable to over-diagnosis.
CONCLUSION: Annual mammography in women aged 40-59 does not reduce mortality from breast cancer beyond that of physical examination or usual care when adjuvant therapy for breast cancer is freely available. Overall, 22% (106/484) of screen detected invasive breast cancers were over-diagnosed, representing one over-diagnosed breast cancer for every 424 women who received mammography screening in the trial.

Prevalence of childhood and adult obesity in the United States, 2011-2012.

Prevalence of childhood and adult obesity in the United States, 2011-2012.
JAMA. 2014 Feb 26;311(8):806-14
Authors: Ogden CL, Carroll MD, Kit BK, Flegal KM

IMPORTANCE: More than one-third of adults and 17% of youth in the United States are obese, although the prevalence remained stable between 2003-2004 and 2009-2010.
OBJECTIVE: To provide the most recent national estimates of childhood obesity, analyze trends in childhood obesity between 2003 and 2012, and provide detailed obesity trend analyses among adults.
DESIGN, SETTING, AND PARTICIPANTS: Weight and height or recumbent length were measured in 9120 participants in the 2011-2012 nationally representative National Health and Nutrition Examination Survey.
MAIN OUTCOMES AND MEASURES: In infants and toddlers from birth to 2 years, high weight for recumbent length was defined as weight for length at or above the 95th percentile of the sex-specific Centers for Disease Control and Prevention (CDC) growth charts. In children and adolescents aged 2 to 19 years, obesity was defined as a body mass index (BMI) at or above the 95th percentile of the sex-specific CDC BMI-for-age growth charts. In adults, obesity was defined as a BMI greater than or equal to 30. Analyses of trends in high weight for recumbent length or obesity prevalence were conducted overall and separately by age across 5 periods (2003-2004, 2005-2006, 2007-2008, 2009-2010, and 2011-2012).
RESULTS: In 2011-2012, 8.1% (95% CI, 5.8%-11.1%) of infants and toddlers had high weight for recumbent length, and 16.9% (95% CI, 14.9%-19.2%) of 2- to 19-year-olds and 34.9% (95% CI, 32.0%-37.9%) of adults (age-adjusted) aged 20 years or older were obese. Overall, there was no significant change from 2003-2004 through 2011-2012 in high weight for recumbent length among infants and toddlers, obesity in 2- to 19-year-olds, or obesity in adults. Tests for an interaction between survey period and age found an interaction in children (P = .03) and women (P = .02). There was a significant decrease in obesity among 2- to 5-year-old children (from 13.9% to 8.4%; P = .03) and a significant increase in obesity among women aged 60 years and older (from 31.5% to 38.1%; P = .006).
CONCLUSIONS AND RELEVANCE: Overall, there have been no significant changes in obesity prevalence in youth or adults between 2003-2004 and 2011-2012. Obesity prevalence remains high and thus it is important to continue surveillance.

Greece's health crisis: from austerity to denialism.

Greece's health crisis: from austerity to denialism.
Lancet. 2014 Feb 22;383(9918):748-53
Authors: Kentikelenis A, Karanikolos M, Reeves A, McKee M, Stuckler D

Greece's economic crisis has deepened since it was bailed out by the international community in 2010. The country underwent the sixth consecutive year of economic contraction in 2013, with its economy shrinking by 20% between 2008 and 2012, and anaemic or no growth projected for 2014. Unemployment has more than tripled, from 7·7% in 2008 to 24·3% in 2012, and long-term unemployment reached 14·4%. We review the background to the crisis, assess how austerity measures have affected the health of the Greek population and their access to public health services, and examine the political response to the mounting evidence of a Greek public health tragedy.

IMPORTANCE: Atrial fibrillation (AF) is the most common rhythm disorder seen in clinical practice. Antiarrhythmic drugs are effective for reduction of recurrence in patients with symptomatic paroxysmal AF. Radiofrequency ablation is an accepted therapy in patients for whom antiarrhythmic drugs have failed; however, its role as a first-line therapy needs further investigation.
OBJECTIVE: To compare radiofrequency ablation with antiarrhythmic drugs (standard therapy) in treating patients with paroxysmal AF as a first-line therapy.
DESIGN, SETTING, AND PATIENTS: A randomized clinical trial involving 127 treatment-naive patients with paroxysmal AF were randomized at 16 centers in Europe and North America to received either antiarrhythmic therapy or ablation. The first patient was enrolled July 27, 2006; the last patient, January 29, 2010. The last follow-up was February 16, 2012.
INTERVENTIONS: Sixty-one patients in the antiarrhythmic drug group and 66 in the radiofrequency ablation group were followed up for 24 months.
MAIN OUTCOMES AND MEASURES: The time to the first documented atrial tachyarrhythmia of more than 30 seconds (symptomatic or asymptomatic AF, atrial flutter, or atrial tachycardia), detected by either scheduled or unscheduled electrocardiogram, Holter, transtelephonic monitor, or rhythm strip, was the primary outcome. Secondary outcomes included symptomatic recurrences of atrial tachyarrhythmias and quality of life measures assessed by the EQ-5D tool.
RESULTS: Forty-four patients (72.1%) in the antiarrhythmic group and in 36 patients (54.5%) in the ablation group experienced the primary efficacy outcome (hazard ratio [HR], 0.56 [95% CI, 0.35-0.90]; P = .02). For the secondary outcomes, 59% in the drug group and 47% in the ablation group experienced the first recurrence of symptomatic AF, atrial flutter, atrial tachycardia (HR, 0.56 [95% CI, 0.33-0.95]; P = .03). No deaths or strokes were reported in either group; 4 cases of cardiac tamponade were reported in the ablation group. In the standard treatment group, 26 patients (43%) underwent ablation after 1-year. Quality of life was moderately impaired at baseline in both groups and improved at the 1 year follow-up. However, improvement was not significantly different among groups.
CONCLUSIONS AND RELEVANCE: Among patients with paroxysmal AF without previous antiarrhythmic drug treatment, radiofrequency ablation compared with antiarrhythmic drugs resulted in a lower rate of recurrent atrial tachyarrhythmias at 2 years. However, recurrence was frequent in both groups.

Association between participation in a multipayer medical home intervention and changes in quality, utilization, and costs of care.

Association between participation in a multipayer medical home intervention and changes in quality, utilization, and costs of care.
JAMA. 2014 Feb 26;311(8):815-25
Authors: Friedberg MW, Schneider EC, Rosenthal MB, Volpp KG, Werner RM

IMPORTANCE: Interventions to transform primary care practices into medical homes are increasingly common, but their effectiveness in improving quality and containing costs is unclear.
OBJECTIVE: To measure associations between participation in the Southeastern Pennsylvania Chronic Care Initiative, one of the earliest and largest multipayer medical home pilots conducted in the United States, and changes in the quality, utilization, and costs of care.
DESIGN, SETTING, AND PARTICIPANTS: Thirty-two volunteering primary care practices participated in the pilot (conducted from June 1, 2008, to May 31, 2011). We surveyed pilot practices to compare their structural capabilities at the pilot's beginning and end. Using claims data from 4 participating health plans, we compared changes (in each year, relative to before the intervention) in the quality, utilization, and costs of care delivered to 64,243 patients who were attributed to pilot practices and 55,959 patients attributed to 29 comparison practices (selected for size, specialty, and location similar to pilot practices) using a difference-in-differences design.
EXPOSURES: Pilot practices received disease registries and technical assistance and could earn bonus payments for achieving patient-centered medical home recognition by the National Committee for Quality Assurance (NCQA).
MAIN OUTCOMES AND MEASURES: Practice structural capabilities; performance on 11 quality measures for diabetes, asthma, and preventive care; utilization of hospital, emergency department, and ambulatory care; standardized costs of care.
RESULTS: Pilot practices successfully achieved NCQA recognition and adopted new structural capabilities such as registries to identify patients overdue for chronic disease services. Pilot participation was associated with statistically significantly greater performance improvement, relative to comparison practices, on 1 of 11 investigated quality measures: nephropathy screening in diabetes (adjusted performance of 82.7% vs 71.7% by year 3, P < .001). Pilot participation was not associated with statistically significant changes in utilization or costs of care. Pilot practices accumulated average bonuses of $92,000 per primary care physician during the 3-year intervention.
CONCLUSIONS AND RELEVANCE: A multipayer medical home pilot, in which participating practices adopted new structural capabilities and received NCQA certification, was associated with limited improvements in quality and was not associated with reductions in utilization of hospital, emergency department, or ambulatory care services or total costs over 3 years. These findings suggest that medical home interventions may need further refinement.

Urinary tract infections in older women: a clinical review.

Urinary tract infections in older women: a clinical review.
JAMA. 2014 Feb 26;311(8):844-54
Authors: Mody L, Juthani-Mehta M

IMPORTANCE: Asymptomatic bacteriuria and symptomatic urinary tract infections (UTIs) in older women are commonly encountered in outpatient practice.
OBJECTIVE: To review management of asymptomatic bacteriuria and symptomatic UTI and review prevention of recurrent UTIs in older community-dwelling women.
EVIDENCE REVIEW: A search of Ovid (Medline, PsycINFO, Embase) for English-language human studies conducted among adults aged 65 years and older and published in peer-reviewed journals from 1946 to November 20, 2013.
RESULTS: The clinical spectrum of UTIs ranges from asymptomatic bacteriuria, to symptomatic and recurrent UTIs, to sepsis associated with UTI requiring hospitalization. Recent evidence helps differentiate asymptomatic bacteriuria from symptomatic UTI. Asymptomatic bacteriuria is transient in older women, often resolves without any treatment, and is not associated with morbidity or mortality. The diagnosis of symptomatic UTI is made when a patient has both clinical features and laboratory evidence of a urinary infection. Absent other causes, patients presenting with any 2 of the following meet the clinical diagnostic criteria for symptomatic UTI: fever, worsened urinary urgency or frequency, acute dysuria, suprapubic tenderness, or costovertebral angle pain or tenderness. A positive urine culture (≥105 CFU/mL) with no more than 2 uropathogens and pyuria confirms the diagnosis of UTI. Risk factors for recurrent symptomatic UTI include diabetes, functional disability, recent sexual intercourse, prior history of urogynecologic surgery, urinary retention, and urinary incontinence. Testing for UTI is easily performed in the clinic using dipstick tests. When there is a low pretest probability of UTI, a negative dipstick result for leukocyte esterase and nitrites excludes infection. Antibiotics are selected by identifying the uropathogen, knowing local resistance rates, and considering adverse effect profiles. Chronic suppressive antibiotics for 6 to 12 months and vaginal estrogen therapy effectively reduce symptomatic UTI episodes and should be considered in patients with recurrent UTIs.
CONCLUSIONS AND RELEVANCE: Establishing a diagnosis of symptomatic UTI in older women requires careful clinical evaluation with possible laboratory assessment using urinalysis and urine culture. Asymptomatic bacteriuria should be differentiated from symptomatic UTI. Asymptomatic bacteriuria in older women should not be treated.

A trial of treatment for acute otorrhea in children with tympanostomy tubes.


A trial of treatment for acute otorrhea in children with tympanostomy tubes.
N Engl J Med. 2014 Feb 20;370(8):723-33
Authors: van Dongen TM, van der Heijden GJ, Venekamp RP, Rovers MM, Schilder AG

BACKGROUND: Recent guidance for the management of acute otorrhea in children with tympanostomy tubes is based on limited evidence from trials comparing oral antibiotic agents with topical antibiotics.
METHODS: In this open-label, pragmatic trial, we randomly assigned 230 children, 1 to 10 years of age, who had acute tympanostomy-tube otorrhea to receive hydrocortisone-bacitracin-colistin eardrops (76 children) or oral amoxicillin-clavulanate suspension (77) or to undergo initial observation (77). The primary outcome was the presence of otorrhea, as assessed otoscopically, 2 weeks after study-group assignment. Secondary outcomes were the duration of the initial otorrhea episode, the total number of days of otorrhea and the number of otorrhea recurrences during 6 months of follow-up, quality of life, complications, and treatment-related adverse events.
RESULTS: Antibiotic-glucocorticoid eardrops were superior to oral antibiotics and initial observation for all outcomes. At 2 weeks, 5% of children treated with antibiotic-glucocorticoid eardrops had otorrhea, as compared with 44% of those treated with oral antibiotics (risk difference, -39 percentage points; 95% confidence interval [CI], -51 to -26) and 55% of those treated with initial observation (risk difference, -49 percentage points; 95% CI, -62 to -37). The median duration of the initial episode of otorrhea was 4 days for children treated with antibiotic-glucocorticoid eardrops versus 5 days for those treated with oral antibiotics (P<0.001) and 12 days for those who were assigned to initial observation (P<0.001). Treatment-related adverse events were mild, and no complications of otitis media, including local cellulitis, perichondritis, mastoiditis, and intracranial complications, were reported at 2 weeks.
CONCLUSIONS: Antibiotic-glucocorticoid eardrops were more effective than oral antibiotics and initial observation in children with tympanostomy tubes who had uncomplicated acute otorrhea.

Effect of a home-based exercise program on functional recovery following rehabilitation after hip fracture: a randomized clinical trial.

Effect of a home-based exercise program on functional recovery following rehabilitation after hip fracture: a randomized clinical trial.
JAMA. 2014 Feb 19;311(7):700-8
Authors: Latham NK, Harris BA, Bean JF, Heeren T, Goodyear C, Zawacki S, Heislein DM, Mustafa J, Pardasaney P, Giorgetti M, Holt N, Goehring L, Jette AM

IMPORTANCE: For many older people, long-term functional limitations persist after a hip fracture.
OBJECTIVE: To determine whether a home exercise program improved function after formal hip fracture rehabilitation ended.
DESIGN, SETTING, AND PARTICIPANTS: Randomized clinical trial conducted from September 2008 to October 2012 in the homes of 232 functionally limited older adults
INTERVENTIONS: The intervention group (n = 120) received functionally oriented exercises.The attention control group (n = 112) received in-home and telephone-based cardiovascular nutrition education.
CONCLUSIONS AND RELEVANCE: Among patients who had completed standard rehabilitation after hip fracture, the use of a home-based functionally oriented exercise program resulted in modest improvement in physical function at 6 months after randomization. The clinical importance of these findings remains to be determined.

Treatment of venous thromboembolism.

Treatment of venous thromboembolism.
JAMA. 2014 Feb 19;311(7):717-28
Authors: Wells PS, Forgie MA, Rodger MA

IMPORTANCE: Venous thromboembolism (VTE), comprising deep vein thrombosis (DVT) and pulmonary embolism (PE), is a common, potentially lethal condition with acute morbidity.
OBJECTIVE: To review the etiology of VTE and the 3 phases of VTE treatment: acute (first 5-10 days), long-term (from end of acute treatment to 3-6 months), and extended (beyond 3-6 months).
EVIDENCE REVIEW: Cochrane reviews, meta-analyses, and randomized controlled trials, as well as other clinical trials for topics not covered by the former, were reviewed. Literature searches using broad terms were used to find meta-analyses published in the last 15 years. The ninth edition of the American College of Chest Physicians Antithrombotic Therapy Guidelines was used to supplement the literature search. Guidelines from specialty organizations were consulted when relevant. The Canadian Agency for Drugs and Technologies in Health was searched for relevant cost-effectiveness studies. We also searched our own literature database of 8386 articles for relevant research.
FINDINGS: Low-molecular-weight heparin (LMWH) along with with vitamin K antagonists and the benefits and proven safety of ambulation have allowed for outpatient management of most cases of DVT in the acute phase. Development of new oral anticoagulants further simplifies acute-phase treatment and 2 oral agents can be used as monotherapy, avoiding the need for LMWH. Patients with PE can also be treated in the acute phase as outpatients, a decision dependent on prognosis and severity of PE. Thrombolysis is best reserved for severe VTE; inferior vena cava filters, ideally the retrievable variety, should be used when anticoagulation is contraindicated. In general, DVT and PE patients require 3 months of treatment with anticoagulants, with options including LMWH, vitamin K antagonists, or direct factor Xa or direct factor IIa inhibitors. After this time, decisions for further treatment are based on balancing the risk of VTE recurrence, determined by etiology of the VTE (transient risk factors, unprovoked or malignancy associated), against the risk of major hemorrhage from treatment. Better prediction tools for major hemorrhage are needed. Experience with new oral anticoagulants as acute, long-term, and extended therapy options is limited as yet, but as a class they appear to be safe and effective for all phases of treatment.
CONCLUSIONS AND RELEVANCE: The mainstay of VTE treatment is anticoagulation, while interventions such as thrombolysis and inferior vena cava filters are reserved for limited circumstances. Multiple therapeutic modes and options exist for VTE treatment with small but nonetheless important differential effects to consider. Anticoagulants will probably always increase bleeding risk, necessitating tailored treatment strategies that must incorporate etiology, risk, benefit, cost, and patient preference. Although great progress has been made, further study to understand individual patient risks is needed to make ideal treatment decisions.

Preterm birth and random plasma insulin levels at birth and in early childhood.

Preterm birth and random plasma insulin levels at birth and in early childhood.
JAMA. 2014 Feb 12;311(6):587-96
Authors: Wang G, Divall S, Radovick S, Paige D, Ning Y, Chen Z, Ji Y, Hong X, Walker SO, Caruso D, Pearson C, Wang MC, Zuckerman B, Cheng TL, Wang X

IMPORTANCE: Although previous reports have linked preterm birth with insulin resistance in children and adults, it is not known whether altered insulin homeostasis is detectable at birth and tracks from birth through childhood.
OBJECTIVE: To investigate whether preterm birth is associated with elevated plasma insulin levels at birth and whether this association persists into early childhood.
DESIGN, SETTING, AND PARTICIPANTS: A prospective birth cohort of 1358 children recruited at birth from 1998 to 2010 and followed-up with prospectively from 2005 to 2012 at the Boston Medical Center in Massachusetts.
MAIN OUTCOMES AND MEASURES: Random plasma insulin levels were measured at 2 time points: at birth (cord blood) and in early childhood (venous blood). The median age was 1.4 years (interquartile range [IQR], 0.8-3.3) among 4 gestational age groups: full term (≥39 wk), early term (37-38 wk), late preterm (34-36 wk), and early preterm (<34 wk).
RESULTS: The geometric mean of insulin levels at birth were 9.2 µIU/mL (95% CI, 8.4-10.0) for full term; 10.3 µIU/mL (95% CI, 9.3-11.5) for early term; 13.2 µIU/mL (95% CI, 11.8-14.8) for late preterm; and 18.9 µIU/mL (95% CI, 16.6-21.4) for early preterm. In early childhood, these levels were 11.2 µIU/mL (95% CI, 10.3-12.0) for full term; 12.4 µIU/mL (95% CI, 11.3-13.6) for early term; 13.3 µIU/mL (95% CI, 11.9-14.8) for late preterm; and 14.6 µIU/mL (95% CI, 12.6-16.9) for early preterm. Insulin levels at birth were higher by 1.13-fold (95% CI, 0.97-1.28) for early term, 1.45-fold (95% CI, 1.25-1.65) for late preterm, and 2.05-fold (95% CI, 1.69-2.42) for early preterm than for those born full term. In early childhood, random plasma insulin levels were 1.12-fold (95% CI, 0.99-1.25) higher for early term, 1.19-fold (95% CI, 1.02-1.35) for late preterm, and 1.31-fold (95% CI, 1.10-1.52) for early preterm than those born full term. The association was attenuated after adjustment for postnatal weight gain and was not significant after adjustment for insulin levels at birth. Infants ranked in the top insulin tertile at birth were more likely to remain in the top tertile (41.2%) compared with children ranked in the lowest tertile (28.6%) in early childhood.
CONCLUSIONS AND RELEVANCE: There was an inverse association between gestational age and elevated plasma insulin levels at birth and in early childhood. The implications for future development of insulin resistance and type 2 diabetes warrant further investigation.

Risk of end-stage renal disease following live kidney donation.

Risk of end-stage renal disease following live kidney donation.
JAMA. 2014 Feb 12;311(6):579-86
Authors: Muzaale AD, Massie AB, Wang MC, Montgomery RA, McBride MA, Wainright JL, Segev DL

IMPORTANCE: Risk of end-stage renal disease (ESRD) in kidney donors has been compared with risk faced by the general population, but the general population represents an unscreened, high-risk comparator. A comparison to similarly screened healthy nondonors would more properly estimate the sequelae of kidney donation.
OBJECTIVES: To compare the risk of ESRD in kidney donors with that of a healthy cohort of nondonors who are at equally low risk of renal disease and free of contraindications to live donation and to stratify these comparisons by patient demographics.
DESIGN, SETTINGS, AND PARTICIPANTS: A cohort of 96,217 kidney donors in the United States between April 1994 and November 2011 and a cohort of 20,024 participants of the Third National Health and Nutrition Examination Survey (NHANES III) were linked to Centers for Medicare & Medicaid Services data to ascertain development of ESRD, which was defined as the initiation of maintenance dialysis, placement on the waiting list, or receipt of a living or deceased donor kidney transplant, whichever was identified first. Maximum follow-up was 15.0 years; median follow-up was 7.6 years (interquartile range [IQR], 3.9-11.5 years) for kidney donors and 15.0 years (IQR, 13.7-15.0 years) for matched healthy nondonors.
MAIN OUTCOMES AND MEASURES: Cumulative incidence and lifetime risk of ESRD.
RESULTS: Among live donors, with median follow-up of 7.6 years (maximum, 15.0), ESRD developed in 99 individuals in a mean (SD) of 8.6 (3.6) years after donation. Among matched healthy nondonors, with median follow-up of 15.0 years (maximum, 15.0), ESRD developed in 36 nondonors in 10.7 (3.2) years, drawn from 17 ESRD events in the unmatched healthy nondonor pool of 9364. Estimated risk of ESRD at 15 years after donation was 30.8 per 10,000 (95% CI, 24.3-38.5) in kidney donors and 3.9 per 10,000 (95% CI, 0.8-8.9) in their matched healthy nondonor counterparts (P < .001). This difference was observed in both black and white individuals, with an estimated risk of 74.7 per 10,000 black donors (95% CI, 47.8-105.8) vs 23.9 per 10,000 black nondonors (95% CI, 1.6-62.4; P < .001) and an estimated risk of 22.7 per 10,000 white donors (95% CI, 15.6-30.1) vs 0.0 white nondonors (P < .001). Estimated lifetime risk of ESRD was 90 per 10,000 donors, 326 per 10,000 unscreened nondonors (general population), and 14 per 10,000 healthy nondonors.
CONCLUSIONS AND RELEVANCE: Compared with matched healthy nondonors, kidney donors had an increased risk of ESRD over a median of 7.6 years; however, the magnitude of the absolute risk increase was small. These findings may help inform discussions with persons considering live kidney donation.

Thirty-day hospital readmission following discharge

Thirty-day hospital readmission following discharge from postacute rehabilitation in fee-for-service Medicare patients.
JAMA. 2014 Feb 12;311(6):604-14
Authors: Ottenbacher KJ, Karmarkar A, Graham JE, Kuo YF, Deutsch A, Reistetter TA, Al Snih S, Granger CV

IMPORTANCE: The Centers for Medicare & Medicaid Services recently identified 30-day readmission after discharge from inpatient rehabilitation facilities as a national quality indicator. Research is needed to determine the rates and factors related to readmission in this patient population.
OBJECTIVE: To determine 30-day readmission rates and factors related to readmission for patients receiving postacute inpatient rehabilitation.
DESIGN, SETTING, AND PATIENTS: Retrospective cohort study of records for 736,536 Medicare fee-for-service beneficiaries (mean age, 78.0 [SD, 7.3] years) discharged from 1365 inpatient rehabilitation facilities to the community in 2006 through 2011. Sixty-three percent of patients were women, and 85.1% were non-Hispanic white.
MAIN OUTCOMES AND MEASURES: Thirty-day readmission rates for the 6 largest diagnostic impairment categories receiving inpatient rehabilitation. These included stroke, lower extremity fracture, lower extremity joint replacement, debility, neurologic disorders, and brain dysfunction.
RESULTS: Mean rehabilitation length of stay was 12.4 (SD, 5.3) days. The overall 30-day readmission rate was 11.8% (95% CI, 11.7%-11.8%). Rates ranged from 5.8% (95% CI, 5.8%-5.9%) for patients with lower extremity joint replacement to 18.8% (95% CI, 18.8%-18.9%). for patients with debility. Rates were highest in men (13.0% [ 95% CI, 12.8%-13.1%], vs 11.0% [95% CI, 11.0%-11.1%] in women), non-Hispanic blacks (13.8% [95% CI, 13.5%-14.1%], vs 11.5% [95% CI, 11.5%-11.6%] in whites, 12.5% [95% CI, 12.1%-12.8%] in Hispanics, and 11.9% [95% CI, 11.4%-12.4%] in other races/ethnicities), beneficiaries with dual eligibility (15.1% [95% CI, 14.9%-15.4%], vs 11.1% [95% CI, 11.0%-11.2%] for no dual eligibility), and in patients with tier 1 comorbidities (25.6% [95% CI, 24.9%-26.3%], vs 18.9% [95% CI, 18.5%-19.3%] for tier 2, 15.1% [95% CI, 14.9%-15.3%] for tier 3, and 9.9% [95% CI, 9.9%-10.0%] for no tier comorbidities). Higher motor and cognitive functional status were associated with lower hospital readmission rates across the 6 impairment categories. Adjusted readmission rates by state ranged from 9.2% to 13.6%. Approximately 50% of patients rehospitalized within the 30-day period were readmitted within 11 days of discharge. Medicare Severity Diagnosis-Related Group codes for heart failure, urinary tract infection, pneumonia, septicemia, nutritional and metabolic disorders, esophagitis, gastroenteritis, and digestive disorders were common reasons for readmission.
CONCLUSIONS AND RELEVANCE: Among postacute rehabilitation facilities providing services to Medicare fee-for-service beneficiaries, 30-day readmission rates ranged from 5.8% to 18.8% for selected impairment groups. Further research is needed to understand the causes of readmission.

Conflicts of interest in approvals of additives to food determined to be generally recognized as safe: out of balance.

Conflicts of interest in approvals of additives to food determined to be generally recognized as safe: out of balance.
JAMA Intern Med. 2013 Dec 9-23;173(22):2032-6
Authors: Neltner TG, Alger HM, O'Reilly JT, Krimsky S, Bero LA, Maffini MV

IMPORTANCE: Food and Drug Administration (FDA) guidance allows food manufacturers to determine whether additives to food are "generally recognized as safe" (GRAS). Manufacturers are not required to notify the FDA of a GRAS determination, although in some instances they notify the agency. The individuals that companies select to make these determinations may have financial conflicts of interest.
OBJECTIVE: To determine the extent to which individuals selected by manufacturers to make GRAS determinations have conflicts of interest between their obligations to ensure that the use of the additive is safe and their financial relationships to the company. DESIGN Using conflict of interest criteria developed by a committee of the Institute of Medicine, we analyzed 451 GRAS notifications that were voluntarily submitted to the FDA between 1997 and 2012.
MAIN OUTCOMES AND MEASURES: Number of GRAS notices submitted to the FDA; frequency of various types of relationships between decision maker and additive manufacturer; frequency of participation on GRAS panels by individuals; and number of GRAS safety determinations identified by the FDA that were not submitted to the agency.
RESULTS: For the 451 GRAS notifications, 22.4% of the safety assessments were made by an employee of an additive manufacturer, 13.3% by an employee of a consulting firm selected by the manufacturer, and 64.3% by an expert panel selected by either a consulting firm or the manufacturer. A standing expert panel selected by a third party made none of these safety assessments. The 290 panels that made GRAS determinations had an average of 3.5 members, with a maximum of 7. Ten individuals served on 27 or more panels; 1 individual served on 128 panels (44.1%). At least 1 of the 10 individuals with the most frequent service was a member of 225 panels (77.6%).
CONCLUSIONS AND RELEVANCE: Between 1997 and 2012, financial conflicts of interest were ubiquitous in determinations that an additive to food was GRAS. The lack of independent review in GRAS determinations raises concerns about the integrity of the process and whether it ensures the safety of the food supply, particularly in instances where the manufacturer does not notify the FDA of the determination. The FDA should address these concerns.

Health care-associated infections: a meta-analysis of costs and financial impact on the US health care system.

Health care-associated infections: a meta-analysis of costs and financial impact on the US health care system.

JAMA Intern Med. 2013 Dec 9-23;173(22):2039-46

Authors: Zimlichman E, Henderson D, Tamir O, Franz C, Song P, Yamin CK, Keohane C, Denham CR, Bates DW


IMPORTANCE: Health care-associated infections (HAIs) account for a large proportion of the harms caused by health care and are associated with high costs. Better evaluation of the costs of these infections could help providers and payers to justify investing in prevention.
OBJECTIVE: To estimate costs associated with the most significant and targetable HAIs.
DATA SOURCES: For estimation of attributable costs, we conducted a systematic review of the literature using PubMed for the years 1986 through April 2013. For HAI incidence estimates, we used the National Healthcare Safety Network of the Centers for Disease Control and Prevention (CDC).
STUDY SELECTION: Studies performed outside the United States were excluded. Inclusion criteria included a robust method of comparison using a matched control group or an appropriate regression strategy, generalizable populations typical of inpatient wards and critical care units, methodologic consistency with CDC definitions, and soundness of handling economic outcomes.
DATA EXTRACTION AND SYNTHESIS: Three review cycles were completed, with the final iteration carried out from July 2011 to April 2013. Selected publications underwent a secondary review by the research team.
MAIN OUTCOMES AND MEASURES: Costs, inflated to 2012 US dollars.
RESULTS: Using Monte Carlo simulation, we generated point estimates and 95% CIs for attributable costs and length of hospital stay. On a per-case basis, central line-associated bloodstream infections were found to be the most costly HAIs at $45,814 (95% CI, $30,919-$65,245), followed by ventilator-associated pneumonia at $40,144 (95% CI, $36,286-$44,220), surgical site infections at $20,785 (95% CI, $18,902-$22,667), Clostridium difficile infection at $11,285 (95% CI, $9118-$13,574), and catheter-associated urinary tract infections at $896 (95% CI, $603-$1189). The total annual costs for the 5 major infections were $9.8 billion (95% CI, $8.3-$11.5 billion), with surgical site infections contributing the most to overall costs (33.7% of the total), followed by ventilator-associated pneumonia (31.6%), central line-associated bloodstream infections (18.9%), C difficile infections (15.4%), and catheter-associated urinary tract infections (<1%).
CONCLUSIONS AND RELEVANCE: While quality improvement initiatives have decreased HAI incidence and costs, much more remains to be done. As hospitals realize savings from prevention of these complications under payment reforms, they may be more likely to invest in such strategies.

Health insurance status and the care of nursing home residents with advanced dementia.

Health insurance status and the care of nursing home residents with advanced dementia.

JAMA Intern Med. 2013 Dec 9-23;173(22):2047-53

Authors: Goldfeld KS, Grabowski DC, Caudry DJ, Mitchell SL


IMPORTANCE: Nursing home residents with advanced dementia commonly experience burdensome and costly hospitalizations that may not extend survival or improve the quality of life. Fragmentation in health care has contributed to poor coordination of care for acutely ill nursing home residents.
OBJECTIVE: To compare patterns of care and quality outcomes for nursing home residents with advanced dementia covered by managed care with those covered by traditional fee-for-service Medicare.
DESIGN, SETTING, AND PARTICIPANTS: Choices, Attitudes, and Strategies for Care of Advanced Dementia at the End-of-Life (CASCADE) was a prospective cohort study including 22 nursing homes in the Boston, Massachusetts, area that monitored 323 nursing home residents for 18 months to better understand the course of advanced dementia at or near the end of life. Data from CASCADE and Medicare were linked to determine the health insurance status of study participants.
EXPOSURES: The health insurance status of the resident, either managed care or traditional fee for service.
MAIN OUTCOMES AND MEASURES: The outcomes included survival, symptoms related to comfort, treatment of pain and dyspnea, presence of pressure ulcers, presence of a do-not-hospitalize order, treatment of pneumonia, hospital transfer (admission or emergency department visit) for an acute illness, hospice referral, primary care visits, and family satisfaction with care.
RESULTS: Residents enrolled in managed care (n = 133) were more likely to have do-not-hospitalize orders compared with those in traditional Medicare fee for service (n = 158) (63.7% vs 50.9%; adjusted odds ratio, 1.9; 95% CI, 1.1-3.4), were less likely to be transferred to the hospital for acute illness (3.8% vs 15.7%; adjusted odds ratio, 0.2; 95% CI, 0.1-0.5), had more primary care visits per 90 days (mean [SD], 4.8 [2.6] vs 4.2 [5.0]; adjusted rate ratio, 1.3; 95% CI, 1.1-1.6), and had more nurse practitioner visits (3.0 [2.1] vs 0.8 [2.6]; adjusted rate ratio, 3.0; 95% CI, 2.2-4.1). Survival, comfort, and other treatment outcomes did not differ significantly across groups. CONCLUSIONS AND RELEVANCE Medicare managed-care programs may offer a promising approach to ensure that nursing homes are able to provide appropriate, less burdensome, and affordable care, especially at the end of life.

Growth in medicare expenditures for patients with acute myocardial infarction: a comparison of 1998 through 1999 and 2008.

Growth in medicare expenditures for patients with acute myocardial infarction: a comparison of 1998 through 1999 and 2008.

JAMA Intern Med. 2013 Dec 9-23;173(22):2055-61

Authors: Likosky DS, Zhou W, Malenka DJ, Borden WB, Nallamothu BK, Skinner JS


IMPORTANCE: Medicare expenditures continue to grow rapidly, but the reasons are uncertain.
OBJECTIVE: To compare expenditures from 1998 through 1999 and 2008 for Medicare beneficiaries hospitalized for acute myocardial infarction (AMI).
DESIGN, SETTING, AND PARTICIPANTS: Cross-sectional analysis of a random 20% sample of fee-for-service Medicare beneficiaries admitted with AMI from 1998 through 1999 (n = 105,074) and a 100% sample for 2008 (n = 212,329).
MAIN OUTCOMES AND MEASURES: Per-beneficiary expenditures, standardized for price and adjusted for risk and inflation. Expenditures were measured across 4 periods: overall (index admission to 1 year), index (within the index admission), early (postindex admission to 30 days), and late (31-365 days). RESULTS Compared with the subjects from 1998 through 1999, those in 2008 were older and had more comorbidities but slightly less ischemic heart disease and cerebrovascular disease. Although there was a 19.2% decline in the rate of hospitalizations for AMI, overall expenditures per patient increased by 16.5% (absolute difference, $6094). Of the total risk-adjusted increase in expenditures, 25.6% occurred within 30 days (22.0% attributed to the index admission), and 74.4% happened 31 to 365 days after the index admission. Spending per beneficiary within 30 days increased by $1560 (7.5%), and spending between 31 and 365 days increased by $4535 (28.0%). Expenditures for skilled nursing facilities, hospice, home health agency, durable medical equipment, and outpatient care nearly doubled 31 to 365 days after admission. Mortality within 1 year declined from 36.0% in 1998 through 1999 to 31.7% in 2008; of the decline, 3.3% was in the 30 days following admission, and 1.0% was in days 31 to 365.
CONCLUSIONS AND RELEVANCE: Between 1998 and 2008, Medicare expenditures per patient with an AMI substantially increased, with about three-fourths of the increase in expenditures occurring 31 to 365 days after the date of hospital admission. Although current bundled payment models may contain expenditures within 30 days of an AMI, they do not contain spending beyond 30 days.

Primary care closed claims experience of Massachusetts malpractice insurers.

Primary care closed claims experience of Massachusetts malpractice insurers.

JAMA Intern Med. 2013 Dec 9-23;173(22):2063-8

Authors: Schiff GD, Puopolo AL, Huben-Kearney A, Yu W, Keohane C, McDonough P, Ellis BR, Bates DW, Biondolillo M


IMPORTANCE: Despite prior focus on high-impact inpatient cases, there are increasing data and awareness that malpractice in the outpatient setting, particularly in primary care, is a leading contributor to malpractice risk and claims.
OBJECTIVE: To study patterns of primary care malpractice types, causes, and outcomes as part of a Massachusetts ambulatory malpractice risk and safety improvement project.
DESIGN, SETTING, AND PARTICIPANTS: Retrospective review of pooled closed claims data of 2 malpractice carriers covering most Massachusetts physicians during a 5-year period (January 1, 2005, through December 31, 2009). Data were harmonized between the 2 insurers using a standardized taxonomy. Primary care practices in Massachusetts. All malpractice claims that involved primary care practices insured by the 2 largest insurers in the state were screened. A total of 551 claims from primary care practices were identified for the analysis.
MAIN OUTCOMES AND MEASURES: Numbers and types of claims, including whether claims involved primary care physicians or practices; classification of alleged malpractice (eg, misdiagnosis or medication error); patient diagnosis; breakdown in care process; and claim outcome (dismissed, settled, verdict for plaintiff, or verdict for defendant).
RESULTS: During a 5-year period there were 7224 malpractice claims of which 551 (7.7%) were from primary care practices. Allegations were related to diagnosis in 397 (72.1%), medications in 68 (12.3%), other medical treatment in 41 (7.4%), communication in 15 (2.7%), patient rights in 11 (2.0%), and patient safety or security in 8 (1.5%). Leading diagnoses were cancer (n = 190), heart diseases (n = 43), blood vessel diseases (n = 27), infections (n = 22), and stroke (n = 16). Primary care cases were significantly more likely to be settled (35.2% vs 20.5%) or result in a verdict for the plaintiff (1.6% vs 0.9%) compared with non-general medical malpractice claims (P < .001).
CONCLUSIONS AND RELEVANCE: In Massachusetts, most primary care claims filed are related to alleged misdiagnosis. Compared with malpractice allegations in other settings, primary care ambulatory claims appear to be more difficult to defend, with more cases settled or resulting in a verdict for the plaintiff.

The quality of supportive cancer care in the veterans affairs health system and targets for improvement.

The quality of supportive cancer care in the veterans affairs health system and targets for improvement.

JAMA Intern Med. 2013 Dec 9-23;173(22):2071-9

Authors: Walling AM, Tisnado D, Asch SM, Malin JM, Pantoja P, Dy SM, Ettner SL, Zisser AP, Schreibeis-Baum H, Lee M, Lorenz KA


IMPORTANCE: Characterizing the quality of supportive cancer care can guide quality improvement.
OBJECTIVE: To evaluate nonhospice supportive cancer care comprehensively in a national sample of veterans.
DESIGN, SETTING, AND PARTICIPANTS: Using a retrospective cohort study design, we measured evidence-based cancer care processes using previously validated indicators of care quality in patients with advanced cancer, addressing pain, nonpain symptoms, and information and care planning among 719 veterans with a 2008 Veterans Affairs Central Cancer Registry diagnosis of stage IV colorectal (37.0%), pancreatic (29.8%), or lung (33.2%) cancer.
MAIN OUTCOMES AND MEASURES: We abstracted medical records from diagnosis for 3 years or until death among eligible veterans (lived ≥ 30 days following diagnosis with ≥ 1 Veterans Affairs hospitalization or ≥ 2 Veterans Affairs outpatient visits). Each indicator identified a clinical scenario and an appropriate action. For each indicator for which a veteran was eligible, we determined whether appropriate care was provided. We also determined patient-level quality overall and by pain, nonpain symptoms, and information and care planning domains.
RESULTS: Most veterans were older (mean age, 66.2 years), male (97.2%), and white (74.3%). Eighty-five percent received both inpatient and outpatient care, and 92.5% died. Overall, the 719 veterans triggered a mean of 11.7 quality indicators (range, 1-22) and received a mean 49.5% of appropriate care. Notable gaps in care were that inpatient pain screening was common (96.5%) but lacking for outpatients (58.1%). With opioids, bowel prophylaxis occurred for only 52.2% of outpatients and 70.5% of inpatients. Few patients had a timely dyspnea evaluation (15.8%) or treatment (10.8%). Outpatient assessment of fatigue occurred for 31.3%. Of patients at high risk for diarrhea from chemotherapy, 24.2% were offered appropriate antidiarrheals. Only 17.7% of veterans had goals of care addressed in the month after a diagnosis of advanced cancer, and 63.7% had timely discussion of goals following intensive care unit admission. Most decedents (86.4%) were referred to palliative care or hospice before death. Single- vs multiple-fraction radiotherapy should have been considered in 28 veterans with bone metastasis, but none were offered this option.
CONCLUSIONS AND RELEVANCE: These care gaps reflect important targets for improving the patient and family experience of cancer care.

Causes and patterns of readmissions in patients with common comorbidities: retrospective cohort study.

Causes and patterns of readmissions in patients with common comorbidities: retrospective cohort study.

BMJ. 2013;347:f7171

Authors: Donzé J, Lipsitz S, Bates DW, Schnipper JL


OBJECTIVE: To evaluate the primary diagnoses and patterns of 30 day readmissions and potentially avoidable readmissions in medical patients with each of the most common comorbidities.
DESIGN: Retrospective cohort study.
SETTING: Academic tertiary medical centre in Boston, 2009-10.
PARTICIPANTS: 10,731 consecutive adult discharges from a medical department.
MAIN OUTCOME MEASURES: Primary readmission diagnoses of readmissions within 30 days of discharge and potentially avoidable 30 day readmissions to the index hospital or two other hospitals in its network.
RESULTS: Among 10,731 discharges, 2398 (22.3%) were followed by a 30 day readmission, of which 858 (8.0%) were identified as potentially avoidable. Overall, infection, neoplasm, heart failure, gastrointestinal disorder, and liver disorder were the most frequent primary diagnoses of potentially avoidable readmissions. Almost all of the top five diagnoses of potentially avoidable readmissions for each comorbidity were possible direct or indirect complications of that comorbidity. In patients with a comorbidity of heart failure, diabetes, ischemic heart disease, atrial fibrillation, or chronic kidney disease, the most common diagnosis of potentially avoidable readmission was acute heart failure. Patients with neoplasm, heart failure, and chronic kidney disease had a higher risk of potentially avoidable readmissions than did those without those comorbidities.
CONCLUSIONS: The five most common primary diagnoses of potentially avoidable readmissions were usually possible complications of an underlying comorbidity. Post-discharge care should focus attention not just on the primary index admission diagnosis but also on the comorbidities patients have.

National trends in patient safety for four common conditions, 2005-2011.

National trends in patient safety for four common conditions, 2005-2011.

N Engl J Med. 2014 Jan 23;370(4):341-51

Authors: Wang Y, Eldridge N, Metersky ML, Verzier NR, Meehan TP, Pandolfi MM, Foody JM, Ho SY, Galusha D, Kliman RE, Sonnenfeld N, Krumholz HM, Battles J


BACKGROUND: Changes in adverse-event rates among Medicare patients with common medical conditions and conditions requiring surgery remain largely unknown.
METHODS: We used Medicare Patient Safety Monitoring System data abstracted from medical records on 21 adverse events in patients hospitalized in the United States between 2005 and 2011 for acute myocardial infarction, congestive heart failure, pneumonia, or conditions requiring surgery. We estimated trends in the rate of occurrence of adverse events for which patients were at risk, the proportion of patients with one or more adverse events, and the number of adverse events per 1000 hospitalizations.
RESULTS: The study included 61,523 patients hospitalized for acute myocardial infarction (19%), congestive heart failure (25%), pneumonia (30%), and conditions requiring surgery (27%). From 2005 through 2011, among patients with acute myocardial infarction, the rate of occurrence of adverse events declined from 5.0% to 3.7% (difference, 1.3 percentage points; 95% confidence interval [CI], 0.7 to 1.9), the proportion of patients with one or more adverse events declined from 26.0% to 19.4% (difference, 6.6 percentage points; 95% CI, 3.3 to 10.2), and the number of adverse events per 1000 hospitalizations declined from 401.9 to 262.2 (difference, 139.7; 95% CI, 90.6 to 189.0). Among patients with congestive heart failure, the rate of occurrence of adverse events declined from 3.7% to 2.7% (difference, 1.0 percentage points; 95% CI, 0.5 to 1.4), the proportion of patients with one or more adverse events declined from 17.5% to 14.2% (difference, 3.3 percentage points; 95% CI, 1.0 to 5.5), and the number of adverse events per 1000 hospitalizations declined from 235.2 to 166.9 (difference, 68.3; 95% CI, 39.9 to 96.7). Patients with pneumonia and those with conditions requiring surgery had no significant declines in adverse-event rates.
CONCLUSIONS: From 2005 through 2011, adverse-event rates declined substantially among patients hospitalized for acute myocardial infarction or congestive heart failure but not among those hospitalized for pneumonia or conditions requiring surgery.

Obesity Rates Rapidly Increase in Developing Countries - weather.com

Yet another reason to encourage decreased sugar consumption. Dare I say more morbidity and mortality comes from sugar consumption than illicit drugs, prescription medications, or even cigarettes or alcohol?

"The Future Diets report looked at how changes in diets worldwide have caused a large spike in obesity rates. The report highlights a 20 percent increase in the consumption of sugar and sweeteners per person from 1961 to 2009."
