MediQuit, an Electronic Deprescribing Tool for Patients on Polypharmacy: Results of a Feasibility Study in German General Practice.

ABSTRACT

BACKGROUND: Deprescribing is an important task for general practitioners (GPs) in the face of risky polypharmacy. The electronic tool "MediQuit" was developed to guide GPs and patients through a deprescribing consultation that entails a drug-selection phase, shared decision making, and advice on safe implementation. OBJECTIVES: A pilot study was conducted to determine the target group of patients that is selected for consultation and to assess the impact, patient involvement, and feasibility of the tool. METHODS: This was an uncontrolled pilot study. GPs from two German regions were invited to use MediQuit in consultations with a view to deprescribing one drug, if appropriate. They selected patients on the basis of broad inclusion criteria. Collected data entailed participants' characteristics, patients' medication lists, deprescribed drugs, and feasibility assessments. Patients were contacted shortly after the consultation and again after 4 weeks. RESULTS: In total, 16 GPs agreed to participate, of whom ten actually performed deprescribing consultations. They selected 41 predominately older patients on excessive polypharmacy. Deprescribing was achieved in 70% of consultations in agreement with patients. Drugs deprescribed were symptom-lowering and preventive drugs (mainly anatomical therapeutic chemical classes A and C). GPs found MediQuit useful in initiating communication on this issue and enhancing deliberations for a deprescribing decision. The median consultation length was 15 min (interquartile range 10-20). At follow-up, GPs and patients infrequently disagreed on which drug(s) was discontinued, and GPs rated patient involvement higher than did patients themselves. DISCUSSION: MediQuit assists in identifying concrete deprescribing opportunities, patient involvement, and shared decision making. The three-step deprescribing procedure is well-accepted once initial organizational efforts are overcome. After revision, further studies are needed to enhance the quality of evidence on acceptance and effectiveness.
