Persons labeled with psychiatric disability have become victims of social and cultural ostracism and consequently have developed a sense of self(More)
BACKGROUND For patients with coronary heart disease, exercise-based cardiac rehabilitation improves survival rate and has beneficial effects on risk factors for coronary artery disease. The relationship between the number of sessions attended and long-term outcomes is unknown. METHODS AND RESULTS In a national 5% sample of Medicare beneficiaries, we(More)
CONTEXT New-onset atrial fibrillation (AF) has been reported in 6% to 20% of patients with severe sepsis. Chronic AF is a known risk factor for stroke and death, but the clinical significance of new-onset AF in the setting of severe sepsis is uncertain. OBJECTIVE To determine the in-hospital stroke and in-hospital mortality risks associated with new-onset(More)
Inverse probability-weighted estimation is a powerful tool for use with observational data. In this article, we describe how this propensity score-based method can be used to compare the effectiveness of 2 or more treatments. First, we discuss the inherent problems in using observational data to assess comparative effectiveness. Next, we provide a(More)
CONTEXT Practice guidelines recommend implantable cardioverter-defibrillator (ICD) therapy for patients with heart failure and left ventricular ejection fraction of 30% or less. The influence of sex and race on ICD use among eligible patients is unknown. OBJECTIVE To examine sex and racial differences in the use of ICD therapy. DESIGN, SETTING, AND(More)

BACKGROUND Changes in the demographics and epidemiology of patients with cardiovascular comorbidities who undergo major noncardiac surgery require an updated assessment of which patients are at greater risk of mortality or readmission. The authors evaluated short-term outcomes among patients with heart failure, coronary artery disease (CAD), or neither who(More)
BACKGROUND Administrative claims data are used routinely for risk adjustment and hospital profiling for heart failure outcomes. As clinical data become more readily available, the incremental value of adding clinical data to claims-based models of mortality and readmission is unclear. METHODS AND RESULTS We linked heart failure hospitalizations from the(More)
