Polypharmacy affects a significant proportion of patients with long-term conditions, particularly older adults. While some polypharmacy is clinically appropriate, the combination of multiple medications, advancing age, and high-risk drug classes can substantially increase the likelihood of adverse events. This tool provides a quick risk stratification to help prioritise which patients may benefit from a more detailed medication review.
Use this tool when triaging patients for medication review, during repeat prescription audits, or when assessing whether a patient's medication burden warrants a structured medication review. It is particularly useful in primary care and care home settings.
This is a screening tool that identifies potential risk based on three factors. It does not account for individual patient tolerability, specific drug interactions, renal or hepatic function, or the clinical appropriateness of each medication. A full clinical review is always required to determine actual risk.
Polypharmacy generally refers to taking five or more regular medications. It is common in older adults and those with multiple long-term conditions, and increases the risk of adverse drug reactions and interactions.
No. 'Appropriate polypharmacy' means every medication has a clear indication and benefit. 'Problematic polypharmacy' is when medications are no longer needed, cause harm, or interact negatively.
The risk tier combines medication count, age band, and the presence of high-risk drug classes. Higher medication counts, older age, and more high-risk drugs increase the risk tier.
These include anticoagulants, insulin, opioids, NSAIDs in older adults, DMARDs, antipsychotics, and other medications with narrow therapeutic windows or significant interaction potential.
A high-risk result suggests a comprehensive medication review is warranted. This tool flags potential concern — clinical judgement determines the appropriate response.
No. This is a screening tool to highlight potential polypharmacy concerns. A full clinical review including patient history and examination is always required.
