About

Medications with anticholinergic properties are frequently prescribed for several conditions in older age; for example cardiovascular drugs (e.g. digoxin, furosemide), urologicals (e.g. darifenacin, oxybutynin) and anti-parkinsonism drugs (e.g. benztropine, trihexyphenadyl). It has been shown that increasing anticholinergic burden (ACB) can cause poor health-related outcomes, but there are still uncertainties around whether it is possible or acceptable to stop medication with high ACB and/or switching to another medication with no or low anticholinergic burden, the effect on health-related outcomes of such an approach, the most appropriate person to deliver this intervention or the health care setting in which it should take place.

The term 'deprescribing' is the process of intentionally stopping a medication or reducing its dose to improve the person's health or reduce the risk of adverse side effects. There is, however, limited research regarding deprescribing. Previously, researchers have suggested deprescribing is a systematic process of identifying and discontinuing drugs in instances in which existing or potential harms outweigh existing or potential benefits within the context of an individual patient's care goals, current level of functioning, life expectancy, values, and preferences. However, there are not many studies about implementation of appropriate interventions to reduce ACB in older patients (aged 65 year and over).

The aim of this non-randomised study is to explore the feasibility of delivering an intervention to reduce the ACB in older patients by deprescribing or switching to inform a future definitive clinical trial. This is a single-arm, open feasibility study conducted in primary and secondary care involving older patients. Mixed method (routine data, questionnaires and interviews) will be used in this study.
