Total ACB Score:
High Risk

Your patient has scored ≥3 and is therefore at a higher risk of confusion, falls and death.

Please review their medications and, if possible, discuss this with the patient and/or relatives/carers. Please consider if any of these medications could be switched to a lower-risk alternative.

When consulting the literature, there are discrepancies between the numerical anticholinergic burden assigned to different medications. In the interest of patient safety, we have opted for the higher burden scores in these instances.

Many of the medications that we commonly prescribe have anticholinergic properties.

In patients over 65 years of age these can cause adverse events, such as confusion, dizziness and falls. These have been shown to increase patient mortality.

You can use this calculator to work out the Anticholinergic Burden for your patients.

A score of 3+ is associated with an increased cognitive impairment and mortality.
