Multimorbidity, readmissions and mortality among older patients with potentially preventable hospitalisations: a Danish nationwide cohort study.
Article in European geriatric medicine, 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
purposeWe investigated the association between multimorbidity level, all-cause 30-day readmissions, and post-discharge 30-day mortality.
methodsUsing Danish national registries, we identified patients aged ≥ 65 years hospitalized for ambulatory care-sensitive conditions between 2013-2018. Multimorbidity was defined as having 2-3 (moderate) or ≥ 4 (severe) of 39 chronic conditions. We estimated 30-day cumulative incidence of readmission after discharge and used Cox regression to calculate hazard ratios (HRs) for readmission and mortality.
resultsAmong 178,445 patients, median age was 78 years (IQR: 71-85), 59% were female. The 30-day readmission rate was 21% for those with severe multimorbidity, compared with 12% for those without multimorbidity and 16% for those with moderate multimorbidity. The hazard of 30-day readmission was elevated for both moderate (HR 1.4, 95% CI 1.4-1.5) and severe (HR 1.9, 95% CI 1.8-1.9) multimorbidity. Additionally, moderate and severe multimorbidity were associated with increased 30-day mortality (HR 1.9, 95% CI 1.7-2.1 and HR 2.6, 95% CI 2.4-2.8, respectively).
conclusionMultimorbidity is associated with increased risk of hospital readmission and mortality, underscoring the need for improved care coordination in acute and post-discharge settings.
