Rationale and objectives: Patient counselling on medication is one of the activities that can and should be performed in community pharmacy. Patient counselling was proved to have a positive effect on clinical outcomes, quality of life, drug/disease knowledge, satisfaction and reduced health-service utilization. Our objective was to assess the degree of concordance between the responses of patient and pharmacist on the same questions regarding provided counselling.
Methods: Data from two questionnaires containing a common block of 14 questions regarding the counselling provided on the medications use, safety concerns, storage, validity term, disposal and disease monitoring was paired and analysed. Questionnaires were paired based on a code and Kappa Cohen coefficient (KCc) and the prevalence adjusted biased adjusted kappa (PABAK) were calculated to evaluate the degree of concordance between pharmacist versus patient responses. The values of the KCc and PABAK were interpreted as per Altman.
Results: For the 14 questions, data from 2047 to 2378 questionnaires collected from 520 community pharmacies in 10 of Romania's counties were analysed. The highest level of concordance ('very good') was achieved on the items regarding the counselling on the medicines' route of administration (PABAK = 0.88), time of administration (PABAK = 0.80) and dosage (PABAK = 0.82). The highest disagreement (week concordance) was found on the question regarding the counselling on the medicines adverse effects (PABAK = 0.01), where 44.8% of patients responded that they received counselling as compared to 93.1% of the pharmacists who responded that they offered counselling. For the rest of the questions, moderate concordance was found.
Conclusion: Overall a moderate level of concordance between patient and pharmacist responses was found on the majority of the questions, with the highest level found for drug use (dosage, route and time of administration). The highest discrepancy was found for the counselling on the medicines adverse effects.
