Resolving Medication-Related Problems in Older Adults through a Multidisciplinary Approach in Korea's Hospital-Based Polypharmacy Program.
Article in Yonsei medical journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposePolypharmacy in older adults is a significant public health challenge. A hospital-based, multidisciplinary Polypharmacy Management Program (PMP) was initiated nationally. We evaluated this team-based program's initial performance, identifying factors associated with medication-related problems (MRPs) prompting prescription changes. MATERIALS AND
methodsWe retrospectively analyzed 2021 PMP data from 1740 patients (33 hospitals). Medication review records, intervention outcome records, and patient demographics were examined. MRPs were identified, classified, and documented alongside prescription modifications. Multivariable logistic regression was used to determine factors associated with prescription modifications.
resultsMRPs were found in 73.5% of patients (average 2.7/patient). Common types were potentially inappropriate medications (PIMs, 58.7%), interactions (46.9%), and adverse drug reactions (ADRs, 26.2%). Pharmacists recommended modifications for 32.4% of MRPs, with 92.2% physician acceptance. Discontinuation (59.2%) was the most common modification, often due to lack of indication or ADRs. Significant predictors for modification included age ≥85 years [adjusted odds ratio (aOR)=2.34], ≥20 medications (aOR=2.46), and use of anticholinergics, multiple oral hypoglycemics, duplicate gastrointestinal agents/proton pump inhibitors or antidementia agents, and certain antidepressants/corticosteroids.
conclusionHospital-based multidisciplinary teams effectively identify and rectify MRPs in older Korean adults with polypharmacy. Targeting interventions towards high-risk subgroups (very elderly, high medication count, specific drugs) could optimize PMP efficiency. Long-term clinical and economic outcome studies are needed.
