An integrative systematic review of nurses' involvement in medication deprescription in long-term healthcare settings for older people.

Background: Deprescription of medications for older people in long-term care settings is crucial to enhance medication safety by reducing polypharmacy and minimizing related adverse events. Nurses as the member of the multidisciplinary healthcare team can support deprescription initiatives, but there is a gap in comprehensive knowledge about their roles.

Objectives: To investigate the role and contribution of nurses in deprescribing medications within the multidisciplinary pharmaceutical care context of long-term healthcare for older people.

Design: A systematic review utilizing an integrative approach was performed.

Methods: Multiple databases were searched, including PubMed (covering MEDLINE), Scopus, CINAHL, ProQuest and Embase, focusing on studies published in English from 2014 to 2024. The preliminary search yielded 4872 studies, which were then refined to 32 qualitative and quantitative studies chosen for data analysis and narrative synthesis. Thematic comparisons and analysis led to the creation of meaningful categories integrating the studies' findings to meet the review's objective.

Results: The review findings were classified into categories: 'necessity and benefits of deprescribing', 'multidisciplinary collaboration for deprescribing', 'nurse role in deprescribing', 'identified challenges to deprescribing', 'involvement of older people and families in deprescribing'. They illustrated and exemplified various aspects of nurses' roles and contributions in deprescription initiatives within the multidisciplinary pharmaceutical care team, such as support for reducing doses, discontinuing medications or transitioning to safer alternatives, as well as factors influencing this process.

Conclusion: The main dimensions of nurses' roles and contributions in deprescription initiatives encompass monitoring, communicating and educating. Challenges to nurses' active participation in deprescribing, such as the need for increased knowledge, confidence and inclusion in team discussions, should be addressed through education, training and changing attitudes. These steps are essential for improving the safety of medication deprescribing in long-term care settings.
