BACKGROUND: Inadequately treated hypertension (HTN) leads to considerable morbidity and mortality. Despite many treatment options, blood pressure (BP) control is suboptimal. Missed opportunities due to the growing complexity of primary care office visits contribute. Electronic health records (EHRs) offer best practice alerts (BPA) tools to support clinicians in identifying poor BP control. BPAs have demonstrated effectiveness for other health outcomes. METHODS: EHR data were collected for patients ≥18 years old seen for primary care office visits prior to, during, and after the BPA active period and used to identify patients for whom the BPA fired or would have fired during control periods. Logistic regression examined the association of BPA activation with follow-up BP check within 14-90 days and with BP control at follow-up, controlling for demographics and health conditions. RESULTS: The BPA active period was associated with reduced patient follow-up; however, a number of covariates were predictive of increased follow-up: Black non-Hispanics, Hispanics, patients on the chronic kidney disease, HTN, or diabetes registries, as well as the morbidly obese, insurance status, and seasonal factors. For those who did follow-up, BPA activation was associated with improved BP control. CONCLUSIONS: BPA activation was associated with worse patient follow-up but improved BP control. Some subgroups had significantly different rates of follow-up and BP control. This study did not have an experimental design as the BPA was a quality improvement initiative. These results highlight the critical importance of planning experimentally designed organizational initiatives to fully understand their impact.
