Detailed Description
A pragmatic cluster randomised control trial will be conducted to evaluate the effectiveness of the IMA intervention in comparison to usual care, in the increase of initiation of medicines for CVD and diabetes (antihypertensive, lipid-lowering, antidiabetic and antiplatelet medications) prescribed in Primary Care (PC). The impact of the IMA intervention on secondary adherence and clinical indicators will be evaluated.
A multicenter pragmatic RCT, with cluster allocation and 2 parallel branches (IMA intervention vs. usual care) based on health records or RWD will be conducted.
PC centres' personnel, including general practitioners (GP), nurses and community pharmacists, from different areas around Catalonia (Spain), will be cluster randomised 1:1 into intervention and control groups, stratified according to the type of PC centre, either rural or urban and taking into consideration the size and localization of the PC centre and the main predictors of non-initiation (socioeconomic status, mean age, % immigrant population of the PC centre).
The IMA intervention will provide clinicians with knowledge, skills and tools to help the patient make an informed decision. PC centre personnel in the intervention group will receive training on medication non-initiation, communication abilities, health literacy, shared decision making and the use of support tools such as leaflets and the IMA website.
Study Design
Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Experimental: Initial Medication Adherence (IMA) intervention General practitioners (GP) will apply the IMA intervention to all patients receiving a new prescription for treatment of cardiovascular disease or diabetes. Following the IMA intervention, nurses and community pharmacists will offer information support in line with the information provided by the GP. |
Behavioral: Initial Medication Adherence (IMA)
The IMA intervention is a shared-decision making intervention that promotes health literacy and patient participation in the decision making process during the recommendation and prescription of a new drug for the management of a cardiovascular disease and diabetes.
The IMA intervention has four main components: training for healthcare professionals (general practitioners (GP), nurses and community pharmacists) on non-initiation, shared-decision making, health literacy and use of decision aids; intervention decision aids (leaflets and website); implementation of the IMA intervention during the GP's consultation; and information support provided by the nurses and community pharmacists that will use the intervention decision aids to explore the patients's doubts and harmonise and standardise the discourse between primary healthcare professionals.
|
Active Comparator: Usual care Patients will receive the usual care when being prescribed a new prescription for treatment of cardiovascular disease or diabetes. Nurses and community pharmacists will be asked to also provide usual care to those patients. |
Other: Usual care
Health professionals in the usual care group will prescribe medication and provide information as usual.

Outcome Measures
Primary Outcome Measures
- Rate of Initiation [1 month and 3 months after recruitment]
Patients who receive a new prescription (a prescription is considered new if there is no previouos prescription from the same group in the previous 6 months) will be considered initiators if they fill-up their prescription in the community pharmacy. Prescription and dispensation databases will be compared to classify prescriptions as initiated and non-initiated.
Secondary Outcome Measures
- Rate of adherence [1 year after recruitment]
Adherence will be calculated based on the Medication Possesion Ratio (MPR is the sum of the days' supply for all fills of a given drug in a particular time period, divided by the number of days in the time period).
- Reduction of Cardiovascular Risk [1 year after recruitment]
Framingham risk score will be calculated.
Other Outcome Measures
- Visits to primary care [1 year after recruitment]
Number of visits to primary care will be counted from electronic health records.
- Visits to secondary care [1 year after recruitment]
Number of visits to secondary care will be counted from electronic health records.
- Visits to emergency room [1 year after recruitment]
Number of visits to ER will be counted from electronic health records.
- Use of diagnostic tests [1 year after recruitment]
Number of diagnostic tests used will be counted from electronic health records.
- Hospital admissions [1 year after recruitment]
Number of inpatient and outpatient hospital admissions will be counted from electronic health records.
- Use of medication [1 year after recruitment]
Number of medication boxes dispensed will be counted from electronic health records.
- Productivity loss [1 year after recruitment]
Sick leaves used as a proxy for productivity loss, counted from electronic health records.
- Cardiovascular events [1 year after recruitment]
All incident events during follow-up, classified according to the International Classification of Diseases, 10th version (ICD10) collected in electronic health records. The events of interest include: Diabetes (E10-E14); dislipidemia (E78); hypertensive diseases (I10-I15); Ischemic heart diseases (I20-I25); other heart diseases (I50, I51); cerebrovascular diseases (I60-I69); diseases of arteries (I70-I79); glomerular diseases (N03, N08) and Acute kidney failure and chronic kidney disease (N17-N19).
- Rate of Mortality [1 year after recruitment]
mortality data from electronic health records
