Implication

Lower 1-year mortality was associated with aspirin, beta-blocker, and thrombolytic use in eligible elderly patients; supports quality improvement but requires prospective validation.

Key Points

To evaluate the feasibility of combining claims-based pattern analysis with medical record abstractions to assess hospital quality of care and risk-adjusted mortality in elderly patients with acute myocardial infarction.
Analyzed risk-adjusted 30-day and 365-day mortality rates using Health Care Financing Administration regression models across six hospitals participating in the Medicare Hospital Information Project pilot (1989–1991).
Abstracted medical records from N=300 Medicare beneficiaries aged 65 years or older with a primary admission diagnosis of acute myocardial infarction.
Evaluated diagnostic coding accuracy, Killip class risk adjustment stability, and guideline-recommended drug utilization rates (aspirin, beta-blockers, and thrombolytic agents).
Diagnostic coding for acute myocardial infarction demonstrated 96% accuracy, with hospital relative mortality rankings remaining stable after excluding ineligible patients and adjusting for Killip class.
Utilization rates among eligible patients were 73% for aspirin, 41% for beta-blockers, and 43% for thrombolytic agents.
Thrombolytic use correlated with reduced 30-day mortality, all three therapies were linked to reduced 1-year mortality, and therapy utilization was lowest in the two hospitals with the highest risk-adjusted mortality.

Structured PICO

Population

300 Medicare beneficiaries 65 years of age or older hospitalized with a primary diagnosis of acute myocardial infarction from 1989 to 1991 in six Connecticut hospitals.

Outcome

Principal diagnosis code verification rates for acute myocardial infarction; observed mortality rates at 30 and 365 days; 30-day standardized mortality ratios; and utilization rates for thrombolytic agents, aspirin, and beta-blockers.hard clinical

Evidence-based therapies for acute myocardial infarction were underutilized in elderly Medicare beneficiaries, highlighting the need for quality improvement efforts.
