Multimedication in Family Doctor Practices: The German Evidence-Based Guidelines on Multimedication

Abstract

Patients with multimorbidity and multimedication require special attention from their treating physicians, as the risks of drug interactions and negative effects on adherence increase with the number of drugs. Most guidelines aim for the treatment of a single disease and do not take potential problems due to multimedication into account. In 2021, updates and evidence-based upgrades of the first version (2012) of the German Guidelines on Multimedication were issued. The aim of the article is to introduce the framework of these evidence-based guidelines, which follows the medication process in six steps: (1) inventory and medication assessment; (2) coordination with the patient; (3) prescription proposal and communication; (4) dispensing of medicines; (5) medication application and self-management; and (6) monitoring. For each step, recommendations and practice tips are presented. The central feature is a structured medication review. The target group is patients with multimorbidity and the concurrent use of five or more drugs. The Medication Appropriateness Index has been modified, and the guiding questions are recommended as guidance for the structured medication review. Overuse and undertreatment are taken into account. The guidelines were consented to in a formal process with 15 medical societies, a patient representative, and experts, as well as piloted in general practices.
