Fragmentation of care between inpatient and outpatient settings can lead to poor patient outcomes. Based on a cohort of veterans ages 65 years or older who had a myocardial infarction, this study examined the use of outpatient medications for secondary prevention (e.g., beta blockers, statins) in the preceding 30 days among patients treated at Veterans Health Administration (VA) versus non-VA hospitals. The researchers found that medication omissions, duplications and delays in prescribing of secondary prevention medications were more common among patients treated at non-VA hospitals.
