Population-Level Health Intervention and Primary Care Quality for Veterans
Authors' conclusion
This cohort study found that implementation of VHA's PHI was associated with improved care quality of care for diabetes and hypertension and did not increase preventable care use, suggesting that the PHI may serve as a model for population health approaches that seek to reengage inactive patients since the COVID-19 pandemic.
Study context
- Population
- Veterans with diabetes and/or hypertension enrolled in Veterans Health Administration (VHA) primary care; data February 2021–February 2022separate matched cohorts per outcome
- Exposure
- Preventive Health Inventory (PHI) receipt vs no PHI
- Outcome
- Diabetes and hypertension clinical quality measures (eg, poor diabetes control, HbA1c >9%) and preventable use outcomes (outpatient care use, preventable ED visits, hospitalizations for ambulatory care-sensitive conditions)
Methodological detailspropensity score-matched, difference-in-differences
- Propensity score-matched

Main finding
As reported in the abstract
Clinical quality measures
PHI vs No PHIDifference in probability of adequate BP control, percentage points (95% CI)
Clinical quality measures
4.0(2.6–5.3)
- Lower with PHI
- difference in probability of poor diabetes control 2.9 percentage points (95% CI −3.8 to −1.9)
Observational data: associations, not effects.
