Potentially inappropriate medications in the elderly: a comprehensive protocol.

Area of Science:

• Geriatrics
• Pharmacology
• Clinical Pharmacy

Background:

• Elderly patients face a higher risk of drug-related morbidity and mortality.
• Potentially inappropriate medications (PIMs) contribute significantly to adverse drug events in older adults.
• Existing screening tools for PIMs have limitations and varying scopes.

Purpose of the Study:

• To review existing screening tools for PIMs in the elderly.
• To develop a new, comprehensive tool integrating PIMs and drug-drug interactions (DDIs).
• To offer alternative therapeutic solutions for identified medication issues.

Main Methods:

• Systematic review of existing PIM screening tools.
• Integration of established lists (Beers, French consensus, McLeod, Lindblad) with Hanlon's and Malone's lists for DDIs.
• Development of a new protocol categorizing drugs based on benefit/risk, efficacy, and disease-specific contraindications.

Main Results:

• The new tool combines PIMs and potentially serious DDIs into a single protocol.
• It categorizes drugs into those to be avoided, those with questionable efficacy, and those contraindicated with specific conditions.
• Alternative therapeutic options are provided alongside identified PIMs and DDIs.

Conclusions:

• A comprehensive tool integrating PIMs and DDIs enhances the quality assessment of geriatric prescribing.
• This integrated approach can lead to improved medication safety and better prescribing practices in the elderly.
• The developed protocol offers a more holistic approach to medication management in older populations.
