BACKGROUND Congestive heart failure is the most common discharge diagnosis for Medicare beneficiaries. While several single-center studies have suggested that these patients are particularly vulnerable to readmission, no recent study, to our knowledge, has reported the readmission rates for a large number of elderly patients with congestive heart failure(More)
OBJECTIVE To evaluate the feasibility of linking claims-based pattern analysis with medical record review in the assessment of quality of hospital care among Medicare beneficiaries with acute myocardial infarction. DESIGN An analysis of risk-adjusted mortality after hospital admission for acute myocardial infarction using the regression model from the(More)
OBJECTIVES To determine how often aspirin was prescribed as a discharge medication to eligible patients 65 years of age and older who were hospitalized with an acute myocardial infarction; to identify patient characteristics associated with the decision to use aspirin; and to evaluate the association between prescription of aspirin at discharge and 6-month(More)
BACKGROUND Although aspirin is an effective, inexpensive, and safe treatment of acute myocardial infarction, the frequency of use of aspirin in actual medical practice is not known. Elderly patients, a group with low rates of utilization of effective therapies such as thrombolytic therapy, also may be at risk of not receiving aspirin for acute myocardial(More)
We sought to determine how often angiotensin-converting enzyme (ACE) inhibitors are prescribed as a discharge medication among eligible patients > or = 65 years old with an acute myocardial infarction; to identify patient characteristics associated with the decision to prescribe ACE inhibitors; and to determine the factors associated with the decision to(More)
This report presents readmission rates following inpatient admissions for the 20 most frequent DRG categories among Medicare inpatients age > or = 65 years, at Connecticut acute-care hospitals during the three-year period FY 1991 to FY 1993. We provide frequency distributions of the 30-day and 365-day readmission rates within these 20 DRG categories. Among(More)
The current study addresses the critical need for research on the therapeutic involvement among adolescent substance users in treatment. Although therapeutic involvement (TI) and the services that clients receive during treatment are among the best predictors of treatment retention and through retention associated with better posttreatment outcomes, there(More)

Frequency distributions of the numbers of discharges within these 20 DRG categories are provided, in aggregate and by(More)
OBJECTIVES We sought to determine the use and association with 30-day mortality of intravenous heparin for the treatment of acute myocardial infarction in elderly patients not treated with a reperfusion strategy and without contraindications to anticoagulation. BACKGROUND The benefit of using full-dose intravenous heparin for the treatment of acute(More)
