Anticholinergic Drug Risk Tool Aims to Prevent Falls

How does the new anticholinergic medication risk tool work?

The Anticholinergic Medication Index, or ACMI, addresses the cumulative effects of medicines with anticholinergic activity. Researchers developed it using linked health records from West Yorkshire and tested it against a separate Welsh dataset. Together, these datasets covered nearly 750,000 older adults, according to [Health Data Research UK](https://www.hdruk.ac.uk/news/new-nhs-ready-medication-risk-tool-could-cut-falls-and-delirium-in-older-people/).

The index includes 88 medicines routinely prescribed in UK primary care. In a Bradford pilot involving patients aged 65 and older, it generated lists showing medication contributions and predicted one-year risk, helping pharmacists identify people needing review. This approach brings medication safety assessment into routine prescribing workflows.

Has the tool been shown to prevent falls and delirium?

The research describes development and external validation of a prediction model. That distinction matters: identifying patients more likely to experience an event does not demonstrate that changing their treatment will prevent it. The clinical benefit depends on which prescribing decisions follow, whether patients can tolerate those changes, and how outcomes compare with usual care.

Implementation has nevertheless begun. An electronic decision-support version is operating in two NHS trusts and recalculates when an anticholinergic medicine is prescribed or stopped, according to [Health Data Research UK](https://www.hdruk.ac.uk/news/new-nhs-ready-medication-risk-tool-could-cut-falls-and-delirium-in-older-people/). This demonstrates practical deployment. Further outcome evaluation would be needed to establish whether it reduces injuries, delirium episodes or hospital admissions.

What should older adults taking several medicines do?

Anticholinergic effects can accumulate across medicines prescribed for different conditions. Potential problems include dry mouth, constipation, difficulty emptying the bladder and impaired cognition, although individual responses vary. A review should weigh the benefit of each medicine against its contribution to the overall burden; a risk score alone cannot determine which treatment should change.

Sudden confusion requires immediate medical attention rather than waiting for a routine medication review. Medicines are one possible cause, but infection, stroke, low blood sugar and other illnesses can also be responsible. Bring the medication list when seeking care and do not assume that confusion is simply part of aging. [NHS guidance on sudden confusion](https://www.nhs.uk/symptoms/confusion/)
