Objective: To evaluate the use of patient self-completion concordance forms and to determine the effect of patient counselling by using concordance forms on adherence to chronic medication.
Methods: Patients with a prescription for new chronic treatment were randomised in an intervention or control group. The intervention group received a concordance form to fill in at home and to discuss during a consultation 2 weeks later in the pharmacy. The control group received the usual information and instruction on how to use the medicine. Afterwards, all patients were asked to fill in a questionnaire about their use of medicines and contact with the pharmacy employees. Adherence to the medicine was determined using rates of prescription refills after 6 months of use.
Results: The questionnaires showed that patients were satisfied about the concordance model. After 6 months of use, 79% of the patients from both intervention and control group were defined as adherent.
Conclusions: There was no significant difference found in adherence between intervention and control group.
Practice implications: Use five selected questions from the concordance form which provided most answers. Focus on one drug group and have more consultation moments.
