The goal of this clinical study is to evaluate whether a structured, clinical pharmacology team-led medication review improves the appropriateness and safety of medication prescribing in elderly nursing home (NH) residents. The study will also assess the impact of the intervention on indicators of inappropriate prescribing and resident-centred clinical outcomes. The main questions the study aims to answer are: 1) Does a structured, digitally supported, medication review led by clinical pharmacologists reduce inappropriate medication prescribing, as measured by the Medication Appropriateness Index (MAI), in elderly NH residents? 2) Does the intervention reduce indicators of inappropriate prescribing, including potentially inappropriate prescriptions, therapeutic duplicates, drug-drug interactions and anticholinergic burden? 3) Does the intervention improve resident-centred clinical outcomes, such as falls, fractures, delirium, hyper-sedation, emergency department visits and hospitalizations? This is a single-arm, non-randomized, pre-post study conducted in seven NHs in Southern Switzerland. Each resident will serve as their own control, with outcomes compared between a 3-month pre-intervention period and a 3-month post-intervention period. The intervention consists of: 1) An individualized, digitally supported, medication review conducted by the team of clinical pharmacologists; 2) Face-to-face feedback to NH healthcare professionals responsible for managing residents' medications; 3) Tailored educational sessions addressing common prescribing issues identified during the medication review. Participants will: be aged 65 years or older and reside in participating NHs; have their routinely collected clinical and medication data assessed during a 3-month pre-intervention period; receive the intervention integrated into routine care, with any medication changes implemented by treating clinicians. The study is low-risk, non-invasive, and embedded in routine NH care. The results will provide evidence on the clinical effectiveness of integrating clinical pharmacology expertise into inter-professional medication management in Swiss NHs.

The study intervention is a multi-component procedure led by a team of clinical pharmacologists to improve medication prescribing among nursing home residents. It includes: 1) individualized medication review with a comprehensive review of each resident's medications, digitally supported; the assessment of medication prescribing appropriateness using the Medication Appropriateness Index (MAI), the identification of key indicators of inappropriate prescribing and the assessment of resident-centred clinical outcomes; 2) face-to-face feedback with nursing home healthcare professionals responsible for managing residents' medications to discuss recommended adjustments for each resident, fostering inter-professional collaboration; 3) tailored educational sessions to nursing home healthcare professionals responsible for managing residents' medications, addressing common prescribing issues identified during medication review. No drugs or medical devices will be used during this procedure.

Medication Appropriateness Index (MAI)
Reduction in the total MAI score per resident between pre-intervention (day 1) and post-intervention (day 180) periods. The MAI is calculated at the medication level for each long-term in-use medication (\>=3 months, excluding as needed medications), using a modified 10-item MAI scoring system. Each medication is scored from 0 to 17 (higher score=greater inappropriateness). A resident-level MAI is calculated by summing the MAI scores of all eligible medications.
Time frame: Pre-intervention (day 1) and post-intervention (day 180), for comparison
Indicator of inappropriate prescribing: potentially inappropriate prescriptions (PIPs)
Frequency of potentially inappropriate prescriptions (PIPs), identified according to the American Geriatrics Society Updated Beers Criteria for Potentially Inappropriate Medication Use in Older Adults (2023). This indicator will be determined for each participant based on the individual medication list.
Time frame: Pre-intervention (day 1) and post-intervention (day 180), for comparison
Indicator of inappropriate prescribing: therapeutic duplicates (TDs)
Frequency of therapeutic duplicates (TDs), defined as the concurrent prescription of two or more drugs within the same Anatomical Therapeutic Chemical (ATC) subgroup at the fourth level. This indicator will be determined for each participant based on the individual medication list.
Time frame: Pre-intervention (day 1) and post-intervention (day 180), for comparison
Indicator of inappropriate prescribing: drug-drug interactions (DDIs)
Frequency of drug-drug interactions (DDIs), assessed by clinical pharmacologists through consultation of Lexicomp (external drug interaction database). This indicator will be determined for each participant based on the individual medication list.
Time frame: Pre-intervention (day 1) and post-intervention (day 180), for comparison
Indicator of inappropriate prescribing: anticholinergic burden (ACB)
Frequency of anticholinergic burden (ACB), evaluated by clinical clinical pharmacologists according to the ACB scale 2012. This indicator will be determined for each participant based on the individual medication list.
Time frame: Pre-intervention (day 1) and post-intervention (day 180), for comparison
Resident-centred clinical outcomes
Frequency of falls, fractures, delirium, hyper-sedation, drug-related emergency department visits and hospitalizations. The occurrence of the specified outcomes will be ascertained through extraction of data from the electronic health records of nursing home residents, where such information is routinely recorded as part of standard clinical documentation.
Time frame: Pre-intervention (day 1) and post-intervention (day 180), for comparison
