- To assess criteria used for detecting underuse of coronary artery revascularization procedures in terms of patient outcomes.
- Retrospective cohort study using medical records supplemented by a telephone survey and review of county death records.
- Four public hospitals and two academically affiliated private hospitals in Los Angeles County, California.
- A total of 671 patients who had coronary angiography between June 1,1990, and September 30,1991, and who met explicit clinical criteria for the necessity of coronary artery bypass graft (CABG) surgery or percutaneous transluminal coronary angioplasty (PTCA).
- For all patients (n=671), we estimated the association between receipt of necessary revascularization and mortality (median follow-up after angiography, 797 days) after adjusting for potential confounders.
For the patients completing the telephone interview (n=374), we examined the relationship between receipt of necessary revascularization and frequency of chest pain.
- Patients who received necessary revascularization within 1 year of angiography had lower mortality than those who did not (8.7% vs 15.8%, P=01), and this association persisted after adjustment for extent of coronary artery disease, clinical symptom complex, ejection fraction, and cardiac surgical risk index.
- Among patients meeting criteria for the necessity of revascularization.
