Sustained Blood Pressure Control Following Discontinuation of a Pharmacist Intervention

Abstract

Team-based care can improve hypertension control. The purpose of the present study was to evaluate blood pressure (BP) control 18months following the discontinuation of a physician-pharmacist collaborative intervention. This was a retrospective analysis of patients who had previously participated in a prospective, cluster randomized, controlled clinical trial.

The study included 228 patients in the control (n=146) or intervention (n=82) groups. The control group contained more patients with diabetes or chronic kidney disease (P
