Barriers and enablers to deprescribing of older adults and their caregivers: a systematic review and meta-synthesis

Purpose: The primary objective of this study was to identify the barriers and enablers to deprescribing from the viewpoint of community-dwelling older adults and their caregivers.

Methods: This meta-synthesis included a systematic review of the literature and an inductive thematic synthesis. Medline and EMBASE were searched for studies that qualitatively explored the perspectives of older adults or their caregivers on deprescribing. Studies had to use qualitative methodologies and include community-dwelling adults (or their caregivers) aged 60 years or older who were taking one or more chronic medications. The quality of studies was assessed using the CASP tool.

Results: Fourteen studies were included in the meta-synthesis. All studies included older adults, and 3 included caregivers or companions. Four barriers were identified: favorable perceptions of medications, fear of medication discontinuation, the complexity of the healthcare system and discouragement from healthcare professionals; and seven enablers were identified: medication safety concerns, patient autonomy and confidence, education, follow-up, deprescribing strategies, relationships with physicians, and patient-perceived benefits of deprescribing.

Conclusion: Multiple barriers and enablers to deprescribing exist within the older adult population. Health system complexity and direct discouragement from healthcare providers were barriers uniquely identified in the older adult population. This population would benefit from interventions to increase their medication literacy, confidence, and autonomy in the deprescribing journey.
