3695 Deprescribing medications with anticholinergic burden in older hospitalised adults: a systematic review
3695 Deprescribing medications with anticholinergic burden in older hospitalised adults: a systematic review
Background: use of anticholinergic medication is increasing, especially among the older population due to polypharmacy and co-morbidities. High anticholinergic burden is associated with adverse effects such as reduced mobility and future dementia risk. Acute hospital stay may be an appropriate time to target this commonly overlooked problem.
Aims: to explore the effects of deprescribing medications with anticholinergic burden on health outcomes of hospitalised older people.
Method: Medline, Web of Science, Cochrane Library and Embase were searched for relevant papers from database inception to September 2024. Studies that involved a deprescribing or medication review intervention to reduce anticholinergic burden within a hospital setting in older people (≥65 years old) were included. Synthesis Without Meta-analysis guidelines were used for narrative synthesis and Joanna Briggs Institute Checklists were used for quality assessment.
Results: 2042 papers were identified, and eight papers were included in this review. There was heterogeneity of design and outcomes across the studies with generally short follow-up. Study designs included: cohort (n = 4), pre-post quasi-experimental (n = 3) and audit (n = 1). Outcomes reported included: medication-related outcomes (n = 8), acceptability (n = 4) and clinical outcomes (n = 1). No studies reported on safety or costs. Six studies reported a reduction in anticholinergic burden score following the intervention, two studies demonstrated a significant reduction in the proportion of patients taking anticholinergic medication following intervention. The quality of the studies varied and ranged from poor to moderate.
Conclusion: this review found that deprescribing interventions within a hospital setting may be acceptable and successful in reducing anticholinergic burden in older adults. However, effectiveness of intervention on important clinical outcomes could not be determined due to short follow-ups and limited data on clinical outcomes, costs, and safety. In future, there is a need for randomised controlled trials to focus on clinical outcomes and involve longer durations of follow-up.

Abstract
Background: use of anticholinergic medication is increasing, especially among the older population due to polypharmacy and co-morbidities. High anticholinergic burden is associated with adverse effects such as reduced mobility and future dementia risk. Acute hospital stay may be an appropriate time to target this commonly overlooked problem.
Aims: to explore the effects of deprescribing medications with anticholinergic burden on health outcomes of hospitalised older people.
Method: Medline, Web of Science, Cochrane Library and Embase were searched for relevant papers from database inception to September 2024. Studies that involved a deprescribing or medication review intervention to reduce anticholinergic burden within a hospital setting in older people (≥65 years old) were included. Synthesis Without Meta-analysis guidelines were used for narrative synthesis and Joanna Briggs Institute Checklists were used for quality assessment.
Results: 2042 papers were identified, and eight papers were included in this review. There was heterogeneity of design and outcomes across the studies with generally short follow-up. Study designs included: cohort (n = 4), pre-post quasi-experimental (n = 3) and audit (n = 1).
