Whether prior use of Veterans Affairs services is a marker for increased mortality was evaluated by using Medicare data for men aged 67 years and older admitted for acute myocardial infarction, chronic heart failure, chronic obstructive pulmonary disease, pneumonia, or stroke during 1996 to 2002. Patients using Veterans Affairs services during the 2 years preceding hospital admission were identified using Veterans Affairs encounter data, and 30-day mortality was compared in patients who did and did not use Veterans Affairs services, adjusting for patient risk factors. ⋯ Results using propensity-matched samples were similar. The use of Veterans Affairs services is not a strong marker of unmeasured severity among patients in private sector hospitals.
