Association between hospital admission either directly or via the emergency department, and readmission rates at 30 days in older adults in two rural hospitals: a retrospective cohort study.

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
introductionOlder patients are frequently re-admitted to the hospital after attending the emergency department (ED). We investigated whether direct admission to the hospital was associated with a lower risk of readmission at 30 days compared to admission via the ED, in patients aged ≥ 75 years.
methodsRetrospective multicenter cohort study from 01/01/2018 to 31/12/2019, including patients aged ≥ 75 years from two hospitals. Patients admitted directly were matched 1:1 with patients admitted via the ED for center, age category, sex, major diagnosis category, type of stay (medical/surgical), and severity. We compared readmission at 30 days (primary outcome) and length of stay (secondary outcome) between groups.
resultsA total of 1486 matched patients with an available outcome measure were included for analysis. We observed no significant difference in 30-day readmission rate between those admitted directly (102/778, 13.1%) and those admitted via the ED (87/708, 12.3%, p = 0.63). There was a significant difference in length of stay between both groups: median 5 days [Q1-Q3: 2-8] vs 6 days [2-11] for direct and ED admissions, respectively (effect size: 0.11, p < 0.001). By multivariate analysis, only moderate to severe denutrition was associated with the risk of readmission at 30 days (Odds Ratio 2.133, 95% Confidence Interval 1.309-3.475).
conclusionThe mode of entry to the hospital of patients aged 75 years and older was not associated with the risk of readmission at 30 days. However, those admitted directly had a significantly shorter length of stay than those admitted via the ED.
