Abstract P325: Early Insights From A Self-measured Blood Pressure Program In A Socially And Economically Disadvantaged Primary Care Population

Abstract

Background: Meta-analyses have shown the success of SMBP in BP control. We aim to describe an SMBP QI program at our primary care clinic and assess its impact on BP. The Einstein CPC is a safety net practice that serves a socially and economically disadvantaged population facing many HTN management barriers. Methods: This program utilized a QI approach for BP control and patient-provider connection. Patient demographics, clinical features, and SDOH were assessed at baseline. Patients with uncontrolled HTN (SBP >140 mmHg) were asked to participate. To date, 111 patients enrolled. Patients were given a Bluetooth-enabled BP monitor connected to a mobile health app, HTN education, DASH diet recommendations, and orientation to SMBP protocols. Those reporting social needs or depression were referred to behavioral resources. Health staff continuously telemonitored patient usage, BP, and individualized interventions. We evaluated the difference in BP from baseline BP and estimated the change in time using a linear multilevel model with random intercept and random slope for each patient. We also calculated time in target range defined as time in SBP 100-130 and DBP 70-80 in mmHg. Results: Patient characteristics (Table 1). Those with at least 3 d of BP readings - 93% (103/111) were included in the BP analysis (Figure 1); mean follow-up 69±67 d and BP readings 42±52. Over 90 d, SBP, and DBP decreased by 11 (95% CI: 4-17) and 5 (95% CI: 3-8) mmHg, respectively. Conclusions: A QI-based SMBP program with robust telemonitoring and individualized interventions may effectively promote short-term adherence to remote BP monitoring and BP control in a socially and economically disadvantaged population.
