Brief summary

This pilot study aims to test the feasibility of the following effectiveness and cost-effectiveness evaluation using Real-World Data.

Detailed description

A cluster non-randomised pilot study with an embedded process evaluation was carried out to test the feasibility of the definitive cluster randomised controlled trial (cRCT). The cRCT will aim to evaluate the effectiveness and cost-effectiveness of the Initial Medication Adherence (IMA) intervention in comparison to usual care, to increase initiation of pharmacological treatments for CVD and diabetes (antihypertensive drugs, hypolipidemic drugs, antiplatelet drugs, and insulin and oral antidiabetics) prescribed in Primary Care (PC). The pilot study was conducted in five PC centres (PCC) in Catalonia (Spain), two were assigned to the control group and three to the intervention group. There were two target participants, the implementation targeted professionals (general practitioners (GP), nurses, and community pharmacists), and the population targeted by the intervention, PC patients. The IMA intervention provided healthcare professionals with the knowledge, skills, and tools to help the patient make an informed and shared decision with the GP to initiate a new CVD or diabetes treatment. Professionals were trained on the problem of non-initiation, communication skills, health literacy, and the use of decision aids (leaflets, website).

Interventions

BEHAVIORALInitial Medication Adherence (IMA) Intervention

The IMA intervention promotes health literacy and patient participation in the decision-making process during the recommendation and prescription of a new drug for the management of cardiovascular disease and diabetes. The IMA intervention has four main components: 1. Training for healthcare professionals (GPs, nurses, and community pharmacists) on non-initiation, shared-decision making, health literacy and use of decision aids; 2. Intervention support tools; decision aids (leaflets and website) and implementation tools (dispensing alert in community pharmacies when dispensing insulins and antiplatelet drugs); 3. Shared decision-making process during the GP's consultation; and 4. Information support provided by the nurses and community pharmacists that use the intervention decision aids to explore the patients' doubts and standardise the discourse between primary healthcare professionals.

OTHERUsual Care

Patients received the usual care when being prescribed a new prescription for treatments of cardiovascular disease or diabetes. Nurses and community pharmacists were asked to also provide usual care to those patients. Community pharmacists from the control group had the dispensing alert available when dispensing insulins and antiplatelet drugs.
