Barriers and enablers to deprescribing in people with a life-limiting disease: A systematic review.

BACKGROUND: Knowing the barriers/enablers to deprescribing in people with a life-limiting disease is crucial for the development of successful deprescribing interventions. These barriers/enablers have been studied, but the available evidence has not been summarized in a systematic review.

AIM: To identify the barriers/enablers to deprescribing of medications in people with a life-limiting disease.

DESIGN: Systematic review, registered in PROSPERO (CRD42017073693).

DATA SOURCES: A systematic search of MEDLINE, Embase, Web of Science and CENTRAL was conducted and extended with a hand search. Peer-reviewed, primary studies reporting on barriers/enablers to deprescribing in the context of explicit life-limiting disease were included in this review.

RESULTS: A total of 1026 references were checked. Five studies met the criteria and were included in this review. Three types of barriers/enablers were found: organizational, professional and patient (family)-related barriers/enablers. The most prominent enablers were organizational support (e.g. for standardized medication review), involvement of multidisciplinary teams in medication review and the perception of the importance of coming to a joint decision regarding deprescribing, which highlighted the need for interdisciplinary collaboration and involving the patient and his family in the decision-making process. The most important barriers were shortages in staff and the perceived difficulty or resistance of the nursing home resident's family - or the resident himself. Conclusion and implications of key findings: The scarcity of findings in the literature highlights the importance of filling this gap. Further research should focus on deepening the knowledge on these barriers/enablers in order to develop sustainable multifaceted deprescribing interventions in palliative care.
