title: Quality of care among elderly patients hospitalized with unstable angina.
abstract: BACKGROUND
  Guidelines for the management of unstable angina have been published by the United States Agency for Health Care Policy and Research (currently known as the Agency for Healthcare Research and Quality); however, little information is available about the quality of unstable angina care, particularly among elderly patients.
  
  
  METHODS
  We examined 1196 elderly Medicare-insured patients hospitalized with unstable angina (ruled out for acute myocardial infarction) at Connecticut hospitals between August and November 1995 to evaluate quality of care provided during hospitalization. Patients without therapeutic contraindications were evaluated for the use of 5 Agency for Health Care Policy and Research guideline-recommended measures: electrocardiographic examination within 20 minutes of admission, use of aspirin on admission, intravenous heparin on admission, achievement of therapeutic anticoagulation among patients provided heparin, and prescription of aspirin on discharge.
  
  
  RESULTS
  Less than half (49.6%) of patients underwent electrocardiographic examination within 20 minutes of admission. After excluding patients with contraindications, aspirin was provided to 80.1% of patients and intravenous heparin to 59.2% of indicated patients, of whom only 43.3% achieved therapeutic anticoagulation. Aspirin was prescribed to 82.3% of eligible patients at discharge. Performance on the 5 quality measures varied widely among hospitals.
  
  
  CONCLUSIONS
  Agency for Health Care Policy and Research guideline-recommended risk stratification and therapeutic interventions are underused in elderly patients hospitalized with unstable angina, with quality of care varying widely among hospitals.
