Interventions to optimise medication prescribing and adherence in older people with cancer: A systematic scoping review.

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.
