Impact of a Pluriprofessional Intervention to Improve Medication Adherence (Secondary Preventive Medication) in Patients After Ischemic Stroke (ADMED-AVC)

Medication adherence is a major factor to prevent vascular recurrence after a first ischemic stroke. Nevertheless, it is suboptimal and the implementation of specific interventions are needed to improve it. A patient - centered and pluriprofessional structured intervention, targeting the medication, introduced at hospital discharge and continued at home (by regular telephone contact) could improve medication adherence one year after stroke. This intervention would consist of semi structured interviews patient-pharmacist at different times during one year after stroke. The information about the therapeutic management of the patient will be shared between healthcare professionals : general practitioners (GP) and community pharmacists (CP), hospital clinical pharmacist (HCP) and physician (HPhys). It will allow for decrease of the recurrent stroke and others cardiovascular complications based on a better adherence to preventive medication. Furthermore the decrease of the iatrogenic events and the improvement of the quality of life of patients may be also associated.

It will be a semi -structured interviews with patient and pharmacist over various time after the stroke (at Month0, M3, M6, M9) combined with patient's therapeutic follow-up from various healthcare professionals.

Initial interview with pharmacist (at the hospital discharge): Evaluation aimed to identify barriers to adherence to drug treatment followed by an information session on the disease, the benefit of drugs and the importance of diet and lifestyle habits. Pharmacist advices focused on how to take medication and how to manage adverse events will be provided. Telephone interviews with hospital clinical pharmacist - patient (at M3 M6 and M9): The objective is to review with the patient its medication-taking routine and its potential difficulties, to motivate adherence to treatment and lifestyle/dietary rules, to give advices about therapeutics and how to take medication. HCP contacts CP to determine the prescription refill. Final interview with HCP pharmacist (at M12): The objective is to take stock with the patient about its taking drug load.

A patient will be considered adherent if: For each secondary-preventive drug (antiplatelet, lipid lowering, and antihypertensive), evaluated by the pharmacy refills: Number of days of medication available to the patient (supplied by the pharmacy divided by the total number of days in the period of the study (365)), is higher than 80%. And score obtained from self-reported adherence questionnaire, greater than 6/8 is obtained for all secondary preventative medication

To estimate the benefit of the intervention on the adherence for each drug, number of days of medication available to the patient (supplied by the pharmacy) divided by the total number of days in the period of the study (365) is higher than 80%.

To estimate the benefit of the intervention on the drug-related iatrogenic events, with a particular attention on the antiplatelet, VKA and the direct oral anticoagulants drugs

To estimate the benefit of the intervention on the recurrence of stroke or another cardiovascular event

Brief IPQR score and medication adherence (treatment adherence score and pharmacy refills) correlation (composite measure)

To estimate in each groups, the satisfaction of patients on their therapeutic follow-up, on their medication, and their relationship with the healthcare professionals (CP , GP , HCP, HPhys)

Realization of a questionnaire (Likert-type scale) assessment of satisfaction of GP and CP in relation to ADMED-AVC program.

To estimate the satisfaction of general practitioners and community pharmacists concerning the ADMED-AVC's program
