Yes / Anticholinergic medicines are associated with adverse outcomes for older people. However, little is known about their use in frailty. The objectives were to (1) investigate the prevalence of anticholinergic prescribing for older patients, and (2) examine anticholinergic burden according to frailty status.
Methods: Cross-sectional analysis of Welsh primary care data from the Secure Anonymised Information Linkage (SAIL) databank including patients aged ≥65 at their first GP consultation between 1st January and 31st December 2018. Frailty was identified using the electronic Frailty Index (eFI) and anticholinergic burden using the Anticholinergic Cognitive Burden (ACB) scale. Descriptive analysis and logistic regression were conducted to 1) describe the type and frequency of anticholinergics prescribed; 2) to estimate the association between frailty and cumulative ACB score (ACB-Sum).
Results: In this study of 529,095 patients, 47.4% of patients receiving any prescription medications were prescribed at least one anticholinergic medicine. Adjusted regression analysis showed that patients with increasing frailty had higher odds of having an ACB-Sum of >3 compared to patients who were fit (mild frailty, adj OR 1.062 (95%CI 1.061–1.064), moderate frailty, adj OR 1.134 (95%CI 1.131–1.136), severe frailty, adj OR 1.208 (95%CI 1.203–1.213)).
Conclusions: Anticholinergic prescribing was high in this older population. Older people with advancing frailty are exposed to the highest anticholinergic burden despite being the most vulnerable to the associated adverse effects. Older people with advancing frailty should be considered for medicines review to prevent overaccumulation of anticholinergic medications given the risks of functional and cognitive decline that frailty presents. / NIHR / Research Development Fund Publication Prize Award winner, May 2023.
