Study protocol for the evaluation of a targeted pharmacist-led service in hypertension management. In this trial, pharmacists recruited to the intervention arm delivered a pharmacist-led service, based on the Health Collaboration Model (HCM) [15]. After initial screening to identify patients with poor BP control, pharmacists optimized a patient’s antihypertensive pharmacotherapy by: systematically identifying the potential cause(s) of poor control; reviewing the use of medicines for hypertension; addressing any adherence issues and/or making therapeutic adjustment recommendations to the patient’s doctor (collaborative care); and monitoring patients at regular intervals (follow-up) to ensure ongoing adherence to medications and assess BP control (Fig. 2)
