Treatment of patients with acute myocardial infarction at a Veterans Affairs (VA) hospital and a non-VA hospital

Abstract

Comparisons of care in Veterans Affairs (VA) hospitals with care in non-VA hospitals are needed to define the future role of the VA health care system. Therefore, the authors conducted a retrospective cohort study of 385 patients who had acute myocardial infarctions and were admitted to a private nonprofit teaching hospital and to a university-affiliated VA hospital, which were staffed by attending and resident physicians from a single medicine department. Data were obtained from hospital databases and from patient records. The authors found that the 206 VA patients, compared with the 179 non-VA patients, were younger and more likely to be men. The VA patients also had higher comorbidity but lower admission severity of illness, according to previously validated measures. Although the VA patients were less likely than the non-VA patients to receive thrombolytic therapy (6% vs 20%, respectively; p < 0.05), they were more likely to undergo coronary angiography (67% vs 57%; p < 0.05) and echocardiography or gated blood pool scanning (54% vs 44%; p < 0.05) during hospitalization. Finally, the VA and the non-VA patients had similar rates of in-hospital mortality in univariate analysis (9% vs 11%, respectively; p = 0.4) and in multivariate analysis, adjusting for covariates. These results suggest that the VA and the non-VA patients who had acute myocardial infarction had similar outcomes and generally received care of similar qualities. Future studies are needed to explore the generalizability of these findings and to provide the data needed to adequately define the VA's future role in American health care.
