Background: Older adults with cancer often require multiple medications (polypharmacy) comprising cancer-specific treatments, supportive care medications (e.g. analgesics), and medications for pre-existing health conditions. Increasing numbers of medications may increase risks of potentially inappropriate prescribing and non-adherence., Objective: To provide an overview of evaluations of interventions aimed at optimising medication prescribing and/or adherence in older adults with cancer., Methods: A systematic scoping review was undertaken. Four databases (PubMed, EMBASE, CINAHL, PsycINFO) were searched using relevant search terms (e.g. cancer, older adults). Eligible studies evaluated interventions seeking to improve medication prescribing and/or adherence in older adults (≥65 years) with cancer using a comparative evaluation. All outcomes for studies that met inclusion criteria were included in the review. Extracted data were collated using tables and accompanying narrative descriptive summaries. The review was reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guidelines., Results: Nine studies met inclusion criteria comprising five randomised controlled trials (RCTs) and four before-and-after study designs. Studies were primarily conducted in oncology clinics, ranging from single study sites to 109 oncology clinics. Sample sizes ranged between 33 and 4844 patients. Interventions most commonly involved patient education (n = 6) delivered by pharmacists or nurses. Three studies reported on prescribing-related outcomes and seven studies reported on adherence-related outcomes, using different terminology and assessment methods. Prescribing-related outcomes focused on medication appropriateness (using Beers criteria) and drug-related problems including drug interactions. Adherence-related outcomes included assessments of self-reported medication adherence and calculation of patients' medication possession ratio., Conclusions: This scoping review highlights a lack of robust evaluations of interventions aimed at optimising medication prescribing and adherence in older adults with cancer. Future research should improve rigour during intervention development, evaluation and reporting in order to generate findings that could inform future practice., (Copyright © 2021 The Author(s).

Background: Older adults with cancer often require multiple medications including cancer-specific treatments and supportive care medications (e.g. analgesics), as well as medications for pre-existing medical conditions. Increasing numbers of medications pose risks of potentially inappropriate prescribing, drug-drug interactions and drug-disease interactions. The burden of treatment (i.e. the workload of healthcare and its impact on patient functioning and well-being) may also negatively affect the way patients take their medications. Non-adherence to medication in patients with cancer is associated with treatment failure and increased healthcare costs. Therefore, it is crucial that medicines are optimised for older adults with cancer to enhance appropriate prescribing, reduce the complexity of treatment regimens and minimise the risk of non-adherence., Objective: To provide an overview of evaluations of interventions aimed at optimising medication prescribing and/or adherence in older adults with cancer., Methods: A systematic scoping review will be undertaken. Four databases will be searched from inception: PubMed, EMBASE, CINAHL and PsycINFO. In order to meet inclusion criteria, studies must evaluate an intervention seeking to improve medication prescribing and/or adherence in older adults (aged ≥65 years) with an active cancer diagnosis using a comparative evaluation (e.g. inclusion of a control group). Two reviewers will independently screen titles and abstracts for inclusion and extract data relating to study population, intervention characteristics, outcome assessments and key findings. Extracted data will be collated using tables, figures and accompanying descriptive summaries. The review will be reported using the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) guidelines., Project Impact: The scoping nature of this review will serve to provide an overview of the existing literature on interventions aimed at optimising medication prescribing and adherence in older adults with cancer. The review findings will help to identify research gaps and highlight areas to explore further in future research., (Copyright © 2020 Elsevier Inc. All rights reserved.)

This paper focuses on the issue of polypharmacy in older people and potential pharmaceutical strategies to optimize the use of multiple medicines. Although polypharmacy has long been viewed negatively, increasing emphasis is being placed on the difference between appropriate and inappropriate polypharmacy. This is largely being driven by the increasing prevalence of multimorbidity and the use of evidence-based guidelines. In this paper, we outline a number of key considerations that are pertinent to optimizing polypharmacy, notably prescribing appropriate polypharmacy, pharmaceutical formulations, the involvement of older people in clinical trials and patient adherence., (Crown Copyright © 2016.

Objective: To summarise the findings of an updated Cochrane review of interventions aimed at improving the appropriate use of polypharmacy in older people., Design: Cochrane systematic review. Multiple electronic databases were searched including MEDLINE, EMBASE and the Cochrane Central Register of Controlled Trials (from inception to November 2013). Hand searching of references was also performed. Randomised controlled trials (RCTs), controlled clinical trials, controlled before-and-after studies and interrupted time series analyses reporting on interventions targeting appropriate polypharmacy in older people in any healthcare setting were included if they used a validated measure of prescribing appropriateness. Evidence quality was assessed using the Cochrane risk of bias tool and GRADE (Grades of Recommendation, Assessment, Development and Evaluation)., Setting: All healthcare settings., Participants: Older people (≥ 65 years) with ≥ 1 long-term condition who were receiving polypharmacy (≥ 4 regular medicines)., Primary and Secondary Outcome Measures: Primary outcomes were the change in prevalence of appropriate polypharmacy and hospital admissions. Medication-related problems (eg, adverse drug reactions), medication adherence and quality of life were included as secondary outcomes., Results: 12 studies were included: 8 RCTs, 2 cluster RCTs and 2 controlled before-and-after studies. 1 study involved computerised decision support and 11 comprised pharmaceutical care approaches across various settings. Appropriateness was measured using validated tools, including the Medication Appropriateness Index, Beers' criteria and Screening Tool of Older Person's Prescriptions (STOPP)/ Screening Tool to Alert doctors to Right Treatment (START). The interventions demonstrated a reduction in inappropriate prescribing. Evidence of effect on hospital admissions and medication-related problems was conflicting. No differences in health-related quality of life were reported., Conclusions: The included interventions demonstrated improvements in appropriate polypharmacy based on reductions in inappropriate prescribing. However, it remains unclear if interventions resulted in clinically significant improvements (eg, in terms of hospital admissions). Future intervention studies would benefit from available guidance on intervention development, evaluation and reporting to facilitate replication in clinical practice., (Published by the BMJ Publishing Group Limited.
