Aims The aim of this study is to investigate whether adverse outcomes for patients admitted with LGB differ depending on weekend versus weekday admission and determine whether any such differences are mediated by the timing of colonoscopy.

Methods Retrospective study from January 2013 to December 2017. Time of admission was recorded defining weekend as midnight Friday to midnight Sunday. Hospital admissions on holydays no weekend were excluded. We used definition for adverse outcomes as the composite outcome: a) Transfusion, b) Treatment (endoscopic, vascular embolization or surgery), c) Clinical intervention (transfusion and treatment), d) Re-bleeding and f) Mortality in patients with LGB.

Our center has endoscopy available 24 hours a day, 7 days a week.

For discrete variables we tested for significant differences between groups with X2 tests If 25 %or more of cells had expected values less than 5; the Fisher exact test was used. For continuous variables we used t-test (two-tailed). P values < 0.05 were considered statistically significant.

Results A total of 452 patients were identified. Of these 348 (73.9%) were admitted during the weekday and 104 (23.1%) during the weekend. Compared to patients admitted on a weekday, weekend admissions had similar adverse outcomes.

Results are resumed in [Table 1].

Conclusions Adverse outcomes no differ depending on weekend versus weekday admission. The timing of colonoscopy no differ on weekday versus weekend. This study was limited by being a single institution study, which could lead to a sampling bias. Our findings should be reevaluated in other healthcare systems under the same socioeconomic conditions.
