Application of an electronic medication management support system.
The aim of the study is to assess the effectiveness of an electronic medication management support system on hospitalization and death, its cost-effectiveness and its effects on the quality and safety of prescribing in patients with polypharmacy.
A parallel, cluster-randomised controlled trial will be conducted in about 1,080 general practices located in the Westphalia-Region (Germany), which care for adult patients covered by BARMER health insurance. Per group, 17,200 clustered-randomized patients (about 32 patients per practice) will be included, if they take ≥ 5 long-term prescriptions (at least 2 consecutive quarters).
In the intervention group, family physicians will use an user-initiated clinical decision support system (CDSS) which provides drug-therapy relevant information (e.g. on diagnoses and treatments) and alerts in case of drug-drug, drug-disease and drug-age interactions. Based on that information, the family physician systematically assesses the appropriateness of patient's medication and optimizes it. Patients receive an updated medication plan in their mother's language, if needed.
In the control group, patients continue to receive usual care where there is no access to the CDSS.
The primary outcome is the combined endpoint of all-cause mortality and all-cause hospital admissions after 15 months. The outcome measures will be based on secondary data (i.e. claims data). Primary and secondary outcomes will be measured at patient level. The primary analysis will be performed adhering to the intention-to-treat (ITT) principle.

Experimental: Computer-assisted medication management
Family physician adds, modifies and optimizes medication in patient's with polypharmacy assisted by an user-initiated computerized decision support system (CDSS) which provides drug-therapy relevant information about patients (e.g. diagnoses and treatments) and alerts in case of drug-drug, drug-disease, drug-age interactions to systematically assess the appropriateness of medication:
Other: CDSS provides drug-therapy relevant information
External computerized decision support system (CDSS: RpDoc® eMMa Software, RpDoc® Solutions GmbH, Saarbruecken) provides drug-therapy relevant information about participating patients with polypharmacy on demand to the general practitioners (GPs) such as data about diagnoses and treatments. The information is based on claims data gathered from all health care professionals involved in the care of the patient (e.g. specialized physicians, other GPs, psychotherapists as well as data about hospital stays and prescription data from pharmacies).
Other: Modification of medication
GPs can add and modify patient's data within the CDSS (e.g. remove drugs which are not taken by the patient anymore, add most recent laboratory findings about kidney function etc.) to enrich and update claims data based information.
Other: Assessment of medication appropriateness
GPs systematically assess the appropriateness of the medication supported by the CDSS, which will alert in case of drug-drug, drug-disease, and drug-age interactions as well as other inappropriateness, such as prescriptions with regard to incorrect dosage or Dear Doctor letters.
Other: Medication plan
GPs print out the updated medication plan including also recommendations for medication use and reasons for prescription in lay language (also available in foreign languages for patients with migration background) as well as recommendations on drugs to use / to avoid including over-the-counter drugs (OTC) (optional) and hand it out to the patient.
Other: Guidance in medication process
GPs receive guidance via the CDSS (e.g. recommendations addressing certain types of medication errors and high risk prescribing, developed by the German Society for Internal Medicine in collaboration with other scientific medical societies).
No Intervention: Control arm
Patients will receive the usual clinical care based on current clinical practice guidelines during intervention period. After completion of trial, the patients in the control group will be invited to participate after written informed consent to receive the intervention.
- Combined endpoint of all-cause mortality and all-cause hospital admissions [ Time Frame: observation period of 15 months ]The primary outcome is the combined endpoint of all-cause mortality and all-cause hospital admissions (including night- and day-only admissions) in patients with polypharmacy.
- Change in the appropriateness of prescriptions [ Time Frame: observation period of 15 months ]Change in the appropriateness of prescriptions: to ascertain whether the complex intervention improves the appropriateness of prescriptions (high-risk prescriptions) in patients with polypharmacy, at T1 minus T0 (T1-T0), measured as the absolute difference in number of inappropriate prescriptions per patient before and after the intervention.
- Change in all-cause hospital admissions [ Time Frame: observation period of 15 months ]Change in all-cause hospital admissions: to evaluate whether the complex intervention reduces all-cause hospital admissions (including day- or night-only admissions) (number and duration) in patients with polypharmacy.
- Change in all-cause mortality [ Time Frame: observation period of 15 months ]Change in all-cause mortality: to assess whether the complex intervention reduces all-cause mortality in patients with polypharmacy.
- Cost Effectiveness [ Time Frame: observation period of 15 months ]Cost-effectiveness of the intervention will be measured by the incremental cost-effectiveness ratio (ICER), which is expressed as the ratio of the difference in overall costs between the control and the intervention group and the difference in effects between both groups.
