Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
A cluster randomized controlled trial with 3-months follow-up will be conducted in 10 Community Health Centers (CHCs) in Indonesia. Patients aged ≥18 years, diagnosed with type 2 diabetes and reported non-adherence to antihypertensive drugs according to the Medication Adherence Report Scale (MARS) are eligible to participate. Patients in the five CHCs randomized to the intervention group will receive a targeted and tailored pharmacist intervention at baseline (first session) and at 1-month follow-up (second session). The intervention will be low-cost, align with the current CHC workflow and will not require a substantial change to the current system. Before dispensing antihypertensive drugs during the first session, the pharmacist will discuss patient-specific barrier(s) for medication adherence based on their responses on MARS and three additional questions, which are derived from the Brief Medication Questionnaires. The intervention strategies will then be tailored to their identified adherence problems. Based on current literature, the investigators defined four non-adherence problems that can be addressed by the community pharmacist, i.e. (1) forgetfulness, (2) lack of knowledge, (3) lack of motivation or (4) other drug-related problems. Of note, patients might need a combined intervention strategy to address all experienced problems. The four non-adherence problems and recommended intervention strategies are specified below:
1. Strategies to cope with forgetfulness include reminders, habit-based strategies and/or involvement of family members.
2. The content of the counselling to cope with lack of knowledge will focus on educating patients about about the purpose of the medication, when and how to take the medication, the need for long-term use, the importance of medication adherence, and how to deal with possible side effects. To explore which education is needed, the patient will be asked whether they know why and how to take their medication. The teach-back method will be used, where the patient is asked to explain the pharmacist what he/she has understood after receiving the education.
3. The content of the counselling to cope with lack of motivation will focus on exploring and discussing the patients' concerns and necessity beliefs (motivational interviewing).
4. The content of the counselling to address other drug related problems will focus on exploring other problems underlying the non-adherence, for example experiencing side effects, costs, polypharmacy, difficulty to refill antihypertensive drugs in time, or medication intake problems, and offering solutions/alternatives when possible.
The follow-up session will be conducted in one month after the baseline session, when patients refill their medication at the next regular outpatient visit. The purpose of the follow-up session is (1) to evaluate the short-term effect of the intervention and discuss the patients' implementation of and experiences with the offered information and recommendations, and (2) to address non-adherence problems that were not yet addressed during the first session. Where needed, the pharmacist, together with patient, can make changes to the coping plan and discuss additional interventions. As the quality of the intervention will depend on the competences and skills of the pharmacist, treatment integrity will be enhanced by an obligatory communication training focusing on motivational interviewing and the teach-back method, and by providing supportive material as part of the intervention.
Patients in five CHCs randomized to the control group will receive pharmacist counselling based on the Indonesian guideline of pharmacy practice. At each visit, they can receive information about the quantity and dose of the dispensed drugs, when and how to use and store the drugs, side effects and how to deal with them, the importance of medication adherence, and confirming if the patient understands how to take medications correctly. Patients in the control group will complete all assessments at the same time points as those in the intervention group
The primary study outcome is the difference between intervention and control group in change in total adherence scores using the MARS between baseline and 3 months follow-up. Secondary outcomes are blood pressure (BP), medication beliefs using the Beliefs about Medicines Questionnaire (BMQ)-specific, and evaluate the intervention using the RE-AIM framework (Reach, Effectiveness, Adoption, Implementation, and Maintenance).

Intervention
A targeted and tailored pharmacist intervention at baseline and at 1-month follow-up.
Reminders, habit-based strategies and/or involvement of family member
Strategies to cope with forgetfulness include reminders, habit-based strategies and/or involvement of family members. The use of a reminder tool and pill boxes will be encouraged and a reminder app can be implemented if patients own a mobile phone. The habit-based strategy will be delivered through a printed worksheet which is tailored to patient's daily routine. Patients will be asked to identify the appropriate place and time to take their medication, and an action they conduct every day that could serve as a prompt or cue to take their medication. Patients will be asked to write coping plans to formulate their own "if-then" plans for all daily doses of their antihypertensive drug(s). Moreover, patients will be asked to choose a family member to become their treatment supporter. This individual will be asked to support patients to take the antihypertensive drugs. Pharmacists will remind patients to take his/her completed worksheet to the next visit.
Counselling to increase knowledge
The content of the counselling to cope with lack of knowledge will focus on educating patients about the purpose of the medication, when and how to take the medication, the need for long-term use, the importance of medication adherence, and how to deal with possible side effects. To explore which education is needed, the patient will be asked whether they know why and how to take their medication. The teach-back method will be used, where the patient is asked to explain the pharmacist what he/she has understood after receiving the education.
Counselling to increase motivation
The content of the counselling to cope with lack of motivation will focus on exploring and discussing their concerns and necessity beliefs. This method is called motivational interviewing. This is done by asking a first question about whether the medication bothers the patient. Follow-up on this question can focus on any concerns or low necessity beliefs (e.g., when patients are bothered by the medication because they think the medication is not needed or are afraid of side-effects).
Explore/address other drug related problems
The content of the counselling to address other drug related problems will focus on exploring these other problems underlying the non-adherence, for example experiencing side effects, costs, polypharmacy, difficulty to refill antihypertensive drugs in time, or medication intake problems, and offering solutions/alternatives when possible.
Control group
Usual care based on the Indonesian guideline at baseline and 1-month follow-up.
