Evaluating the impact of medication review and deprescribing on prescribing appropriateness and clinical outcomes in older people residing in long-term care facilities: a systematic review and meta-analysis.
Synthesis in Age and ageing, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundPolypharmacy is a major concern among older adults in long-term care facilities (LTCFs), as it increases the risk of potentially inappropriate medications (PIMs) and related adverse outcomes. Medication review and deprescribing interventions may help optimise therapy and reduce harm.
designSystematic review and meta-analysis.
methodsThis study was conducted according to PRISMA guidelines (PROSPERO: CRD42023486056). PubMed, Embase and Scopus were searched up to 27 August 2024, for experimental studies evaluating the impact of medication review/deprescribing interventions in older LTCF residents with polypharmacy. Outcomes included medication appropriateness indexes, falls, hospitalisations and mortality. We calculated risk ratios for dichotomous data and mean differences for continuous data [with 95% confidence intervals (CIs)]. The quality of the studies was assessed using RoB 2 for the randomised controlled trials (RCTs) and the ROBINS-I for non-randomised studies.
resultsFrom 3548 records, 38 studies (22 RCTs, 16 quasi-experimental) were included. Pooled analyses demonstrated significant reductions in the number of drugs per patient [within 12 months: -0.89 (95% CI -1.46, -0.32); at ≥12 months: -1.60 (95% CI -2.68, -0.52)] and in PIMs [at 6 months: -0.48 (95% CI -0.74, -0.22); at ≥12 months: -0.26 (95% CI -0.40, -0.13)]. No significant effects were observed on falls, hospitalisations or mortality. Studies showed wide methodological heterogeneity and had moderate to high risk of bias (23 moderate, 14 high, 1 low).
conclusionsComprehensive medication review interventions improved prescribing appropriateness in older LTCF residents with polypharmacy but did not significantly affect clinical outcomes (i.e. falls, hospitalisations and mortality). Further high-quality studies using standardised approaches are needed.
