title: Improving care for unstable angina patients in a multiple hospital project sponsored by a federally designated quality improvement organization.
abstract: In 1992, the Health Care Financing Administration (HCFA) implemented a major change in the methodology of the quality of care oversight activities conducted by Medicare Peer Review Organizations. The Health Care Quality Improvement Program (HCQIP) represented a shift in oversight activity direction from identifying and dealing with individual clinical errors to helping providers improve mainstream care. The change in the oversight activities of Peer Review Organizations has been so substantial that the organizations are now commonly referred to as Quality Improvement Organizations (QIOs). Since its introduction, the HCQIP has developed multiple cooperative projects between QIOs and participating hospitals to examine specific processes of care and to ultimately improve the quality of care provided to Medicare patients. This report describes one project in North Carolina focusing on inpatient treatment of patients with a principal diagnosis of unstable angina, one of the most frequent causes of hospital admissions for Medicare patients. Based on the guidelines for treating unstable angina issued by the Agency for Health Care Policy and Research, 5 measures of good medical care for these patients were selected as quality of care indicators. A total of 16 hospitals in North Carolina each provided medical records of approximately 50 Medicare patients discharged with a principal diagnosis of unstable angina. Our findings indicated that guidelines-recommended standard of care were met in only a minority of patients. These indicators of care--including ordering an electrocardiogram within the first hour of admission and admitting high-risk patients to the intensive care unit--all occurred in <50% of the patients. Moreover, use of drugs that improve outcomes in patients with unstable angina was lower than expected. Only 17% of eligible patients with unstable angina were discharged on a lipid-lowering medication. Although there was variation in compliance with the guidelines between types of hospitals, all hospitals had an opportunity to improve in at least one quality of care indicator. The data demonstrate that significant variances exist between published guidelines and actual practices. Given the high rates of readmission for patients with coronary disease, there is opportunity to improve compliance with recommended guidelines of good care. The new oversight activity direction taken by Medicare should ultimately improve care for more patients than could ever be achieved through individual case review.
