Limited impact of weekend admissions on hip fracture outcomes in elderly patients: A study from a Japanese nationwide medical claims database.
Article in Geriatrics & gerontology international, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 papers.
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
aimThe effectiveness of early surgery in preventing complications in elderly Japanese hip fracture patients and the impact of weekend hospitalization need further investigation. The purpose of this study was to determine whether weekend hospitalization affects the incidence of various sequelae and death during hospitalization in elderly hip fracture patients using a comprehensive Japanese hip fracture case database.
methodsWe retrospectively analyzed the Japanese National Administrative DPC (Diagnosis Procedure Combination) database from April 2016 to March 2022. During this period, approximately 1100 DPC-affiliated hospitals consistently provided medical records with consent for the study. The study focused on weekend hospitalizations and investigated the associations with postoperative pneumonia, pulmonary embolism, myocardial infarction, urinary tract infection, acute renal dysfunction, dementia, and in-hospital mortality after propensity score matching. Owing to the large population size of the study, significance levels were strictly enforced, and a P-value < 0.001 was considered statistically significant.
resultsAfter performing propensity score matching based on age, sex, and comorbidities, 111 035 patient pairs were identified, comparing those admitted on weekends versus weekdays. The analysis showed no heightened risk of sequelae for those admitted during the weekend compared with weekdays. Additionally, there was a slight trend toward higher mortality risk during weekend hospital stays; however, the increase was insignificant, with a hazard ratio of 1.071 (95% confidence interval: 1.005-1.140, P = 0.03).
conclusionThe results of this study indicate that weekend hospitalization for elderly patients with hip fractures is not definitively associated with an increase in various sequelae or in-hospital mortality and that the importance of early surgery for elderly patients with hip fractures may be recognized and promoted in Japan.
