Introduction: The Community Practice Center (CPC) in North Philadelphia serves a community with significant socioeconomic barriers leading to inability to access care necessary for management of hypertension (HTN). Prior studies have shown the efficacy of SMBP programs in improving blood pressure (BP) control. Methods: All sequential patients presenting to the CPC with stage 2 HTN were screened for eligibility. Upon enrollment, patients received a Bluetooth-enabled BP cuff connected to a mobile health app and HTN education. Patients completed validated social and behavioral assessments including social determinants of health (SD)H) assessment via WellRx screen, depression screening (PHQ-9), and self-efficacy screening ( Self-Efficacy to Manage Chronic Disease Scale ). A behavior change plan was created using Brief Problem Solving Therapy based on the aforementioned assessments. Staff continuously monitored usage, BP, and provided individualized interventions. We conducted a cross-sectional quality improvement study using daily BP data from June 2022 - April 2023 to assess the correlation between baseline sociodemographic characteristics and Time in Target Range (TTR) through multivariable linear regression. We calculated TTR, defined as the percentage of time with systolic BP within 100-130 mmHg, through linear interpolation. Results: A total of 133 patients were enrolled in the program. We analyzed data from 78 patients with ≥3 days of readings (average 33; SD 49) and complete baseline characteristics (Table 1). Female sex and non-smoking status were associated with TTR, while diabetes, positive depression screening, positive SDOH screening, and self-efficacy were not (Table 2). Conclusions: In a socioeconomically disadvantaged population participating in a comprehensive SMBP program, depression, SDOH, and self-efficacy screening at time of enrollment did not predict TTR. Participation in a SMBP program may be valuable in these populations.

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.
