Pharmacist intervention for blood pressure control: medication intensification and adherence.

The objective of this study was to describe medication adherence and medication intensification in a physician-pharmacist collaborative management (PPCM) model compared with usual care. This study was a prospective, cluster, randomized study in 32 primary care offices from 15 states. The primary outcomes were medication adherence and anti-hypertensive medication changes during the first 9 months of the intervention. The 9-month visit was completed by 539 patients, 345 of which received the intervention. There was no significant difference between intervention and usual care patients in regards to medication adherence at 9 months. Intervention patients received significantly more medication changes (4.9 vs.1.1; P = .0003) and had significantly increased use of diuretics and aldosterone antagonists when compared with usual care (P = .01).The PPCM model increased medication intensification; however, no significant change in medication adherence was detected. PPCM models will need to develop non-adherence identification and intervention methods to further improve the potency of the care team.
