Objectives: The aim was to determine the impact of a telephone counseling service, provided bi-monthly by pharmacist, on patients' beliefs about antihypertensive medicines and blood pressure (BP) control.
Methods: Either hypertensive patients were randomly assigned to a control group (CG, usual care) or an intervention group (IG). All patients had BP values registered and filled in the Italian version of the Belief Medicine Questionnaire (BMQ). After 12 months, patients filled in the BMQ again and had their self-reported BP registered. The intervention consisted of an educational/counseling session based on patients' needs assessment provided bi-monthly by a pharmacist for one year via telephone.
Results: 80 CG and 84 IG patients were recruited. After 12 months, there were significant differences between IG and CG for both BMQ's Necessity and Concern score (p < 0.001; p < 0.001 respectively) and a significant reduction in BP values in IG (p < 0.001).
Conclusions: The intervention improves BP control by modifying patients' perception about treatments and involving patients as participants in the management of their health.
Practice implications: This paper could serve as a guideline for other studies to confirm the effectiveness of this intervention in modifying health behavior, and the role of hospital pharmacist.
