Acute myocardial infarction quality of care: the Strong Heart Study.

OBJECTIVES: Evaluate the quality of care provided patients with acute myocardial infarction and compare with similar national and regional data. DESIGN: Case series. SETTING: The Strong Heart Study has extensive population-based data related to cardiovascular events among American Indians living in three rural regions of the United States. PARTICIPANTS: Acute myocardial infarction cases (72) occurring between 1/1/2001 and 12/31/2006 were identified from a cohort of 4549 participants. OUTCOME MEASURES: The proportion of cases that were provided standard quality of care therapy, as defined by the Healthcare Financing Administration and other national organizations. RESULTS: The provision of quality services, such as administration of aspirin on admission and at discharge, reperfusion therapy within 24 hours, prescription of beta blocker medication at discharge, and smoking cessation counseling were found to be 94%, 91%, 92%, 86% and 71%, respectively. The unadjusted, 30 day mortality rate was 17%. CONCLUSION: Despite considerable challenges posed by geographic isolation and small facilities, process measures of the quality of acute myocardial infarction care for participants in this American Indian cohort were comparable to that reported for Medicare beneficiaries nationally and within the resident states of this cohort.
