Key Points Question What is the association between care fragmentation and acute care use among Veterans at high risk of hospitalization or death enrolled in Department of Veterans Affairs Home-Based Primary Care (HBPC)? Findings In this cohort study of 8908 patients in HBPC at high risk of hospitalization or death, dispersion of outpatient care across more health care practitioners was associated with increased odds of an emergency department visit or a hospitalization for an ambulatory care sensitive condition, while higher concentration of care with the HBPC team was associated with reduced odds of acute care use. Meaning These findings suggest that consolidating and/or coordinating fragmented care among HBPC patients may be associated with a reduction in preventable acute care.
