Background: Nearly half of adults in the United States have hypertension, although only 22.5% are considered controlled. Studies have shown that pharmacist intervention can improve management of hypertension through scheduled pharmacy appointments. However, no studies appear to examine pharmacist impact on blood pressure during nurse visit appointments where clinical pharmacy is not physically present. The purpose of this study was to determine whether immediate remote blood pressure consultation by clinical pharmacy specialists reduces time to blood pressure goal in patients diagnosed with hypertension.
Methods: This IRB-exempt, observational, retrospective cohort study was conducted within an integrated healthcare delivery system. This study included adult patients diagnosed with hypertension who had a blood pressure reading between 140-179/90-109 mmHg after repeat check at a nurse visit from November 2023 to August 2024. Patients were excluded from the study if they were pregnant, receiving hospice/palliative care, or had a GFR < 30 mL/min/1.73 m
2. Patients in the treatment group received an immediate consultation from a remote, on-call pharmacist for medication review and optimization as needed. Patients in the control group received usual care where the “Doctor of the Day” was consulted for recommendation(s) as their schedule permitted. The primary outcome of this study
was to assess time to blood pressure goal (defined as ≤ 140/90 mmHg) for patients managed by the “On the Spot” pharmacy hypertension consult service compared to patients who received usual care. The secondary objectives were to evaluate medication optimization, change in blood pressure from baseline, and the percentage of patients who achieved blood pressure goal compared to usual care. The tertiary objective was to compare the percentage of patients enrolled in remote blood pressure monitoring (RBPM) where “On the Spot” was utilized versus usual care. Results were assessed at 4 months post intervention and data was analyzed using descriptive statistics.
Results:The study included 1,726 participants with 1466 patients in the control group and 260 patients in the intervention group. The average time to achieve blood pressure control was 31.93 ± 27.43 days in the control group and 31.21 ± 25.85 days in the intervention group, showing no statistically significant difference (p=0.72). Patients that received medication changes on the day of the nurse visit at a higher rate in the intervention group (62.31%) compared with the control group (35.54%, p<0.0001). The percentage of patients who achieved the blood pressure goal of ≤ 140/90 mmHg was similar between both groups with 87.08% in the control group and 88.21% in the intervention group (p= 0.51). Similarly, changes in systolic and diastolic blood pressure from baseline were comparable in the control and intervention groups (systolic: -24.91 vs. -23.06 mmHg, p = 0.13; diastolic: -8.27 vs. -9.76 mmHg, p = 0.09, respectively). The percentage of patients enrolled in RBPM was significantly higher in the intervention group at 63.08% versus 6.55% in the control group (p<.0001).
Conclusion:The "On the Spot" remote pharmacy hypertension consult service demonstrated a significant impact on process measures, including higher rates of medication optimization and enrollment in RBPM compared to usual care. While the time to blood pressure control and overall blood pressure control rates were similar between groups, the higher medication intervention rates and RBPM enrollment suggest that integrating remote pharmacist consults into nurse visits enhances hypertension management workflow efficiency. Benefits include reducing delays in care, clearing physician and nurse schedules, and increasing rate of follow up. These findings highlight the value of immediate remote pharmacist intervention and underscore the potential for integrated remote pharmacy services to enhance hypertension management in healthcare systems.
