[Medication reviews in community pharmacies: An approach to external quality assessment]

A medication review aims at the optimization of medication use, the detection of drug-related problems (DRPs) and the recommendation of interventions. As part of the pilot project "Arzneimittelinitiative Sachsen-Thüringen" (ARMIN) and caused by the introduction of several training programs, numerous public pharmacies in Germany currently offer medication reviews for patients. However, a standardized method for external quality control has so far not been established.

A round robin test for medication reviews was designed in written form by five pharmacists with expertise in different areas (Drug information service ARMIN, Saxonian Chamber of pharmacists, public pharmacy, hospital pharmacy), based on the recommendations of the guideline for medication reviews of the German Federal Chamber of Pharmacists (Bundesapothekerkammer). On the basis of a fictitious case study the participants were asked to check a patient's medication data for the presence of DRPs, propose possible solutions and generate a medication plan. The solutions were assessed by two pharmacists of the drug information service ARMIN on the basis of a best practice solution that had been consented in the study group beforehand.

102 pharmacists and 13 pharmacy students in internship took part in the round robin test. On average, participants achieved a score of 7,62 out of 9 for recognizing DRPs and recommending solutions and a score of 0,79 out of 1 for generating a correct medication plan. 106 participants (92%) met the requirements for successful participation (recognizing the three most relevant DRPs and at least one further DRP as well as generating an adequate medication plan). The implementation of the approach described here proved to be practicable The State Directorate of Saxony accepted the round robin test as a measure for external quality assessment in accordance with legal requirements.

Due to the nationwide introduction of medication reviews as a pharmaceutical service in June 2022, medication reviews performed by German community pharmacies will gain in importance in the coming years. This is why quality assurance is necessary. Since the participants' performance in medication analysis becomes comparable by completing the round robin test, this instrument appears to be potentially suitable for the external quality assessment of medications reviews nationwide.
