What is the association of the Preventive Health Inventory (PHI), a multicomponent care management tool, with primary care quality measures for diabetes, hypertension, and preventable health care use?In this cohort study of multiple propensity score–matched cohorts of veterans with diabetes and/or hypertension, those who received care using the PHI had improved diabetes and hypertension control and no associated increase in preventable health care use compared with similar veterans not receiving PHI.These findings suggest that the use of a multicomponent care management intervention may serve as a model for population health approaches that seek to reengage inactive patients since the COVID-19 pandemic.
