Risk factors for 30-day unplanned readmissions after surgical procedures in the elderly population.

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
introductionUrgent hospital readmissions within 30 days of discharge after surgery are a measure of the quality of health and social care. This study aims to identify the characteristics of patients at higher risk of readmission and the main reasons for readmission, stratified by type of surgery.
methodsThis cross-sectional study analysed the medical records of patients over 60 years of age in 2022 who had undergone surgery. Records came from hospitals covering an area of 890,000 inhabitants in Northern Italy (ULSS Marca Trevigiana). Risk factors for readmission included demographic characteristics, hospitalisation details, comorbidities, and procedures. Readmission rates and 95% CI were calculated by risk factor, type of intervention and reason for readmission. A logistic model was used to estimate the OR of readmission, adjusting for potential confounders.
resultsThe overall 30-day readmission rate was 3.8% (3.5-4.3), with the highest rates after gastrointestinal surgery (49.7 per 1,000 admissions) and the lowest after skin-soft tissue surgeries (15.5 per 1,000 admissions). Multivariate analysis identified dementia (OR = 3.19), end-stage kidney disease or dialysis (OR = 2.84), and metastatic cancer (OR = 2.65) as strong predictors of readmission. Advanced age (75+), male gender, primary cancer, and anemia were also independent predictors. Infection was the main reason for readmission. Other significant causes were hemorrhage, thrombosis/embolism, and intestinal obstruction.
conclusionsThe study highlights the importance of identifying risk factors for readmission to improve transitions of care. Targeted interventions for high-risk populations, particularly those with dementia, renal disease, or cancer, are essential to improve postoperative outcomes and alleviate the burden of unplanned readmissions on healthcare systems.
