Outline

Text

Background and aims: There is a need to carefully weigh the risks and benefits of medication in older adults with multimorbidity and polypharmacy. Aims are: 1) to identify the evidence on risks and benefits of drugs commonly used in older adults; 2) to provide recommendations on their use, which can be incorporated into an electronic decision support tool (eDS-tool) aimed at supporting general practitioners to reduce inappropriate prescriptions.

Methods: A set of systematic reviews (SR) was planned for n = 24 drugs and indications. For each SR a study protocol was developed, and the PICOS-framework was used for the development of the search terms; literature search comprised three searches, each of which being undertaken only if the previous one did not yield high quality results: searches 1 and 2 identified SRs and meta-analyses in the Cochrane Database of Systematic Reviews and DARE, and in MEDLINE, EMBASE, HTA and IPA, respectively. Search 3 identified clinical trials and observational studies from SRs not included in searches 1 and 2 but containing eligible studies, and from the databases considered in search 2. Inclusion criteria: studies evaluating the risks and benefits of the corresponding drug and indication; significant number of participants aged ≥65 or subgroup analysis of this population; clinically relevant endpoints. Selection of studies, data extraction and quality appraisal were performed by two reviewers independently. Based on the evidence found the recommendations were developed using the GRADE methodology, and integrated in the eDS-tool.

Results: Currently, n = 18 SRs are completed and n = 6 SRs are ongoing. In general, the amount of studies included and the quality of the evidence are low. So far, n = 41 recommendations for the following drugs have been developed: metformin, sulfonylureas, gliptins, glitazones, non-steroidal anti-inflammatory drugs, statins, beta-blocking agents, Vitamin K antagonists, new oral anticoagulants, nitrates, calcium channel blockers, thiazides, platelet inhibitors and high ceiling diuretics.

Discussion: Our work reflects a general lack of high quality evidence regarding drug treatment of older people with multiple conditions. Recommendations are currently checked by external review and will then be integrated in the eDS-tool. The eDS-tool will be tested in a randomised controlled trial with clinically relevant endpoints. This study is part of the 7th Framework European Project PRIMA-eDS (Grant No. 305388-2).
