    Background And AimsGI angiodysplastic (GIAD) lesions are an important cause of blood loss throughout the GI tract, particularly in elderly persons. The aim of this study was to determine whether mortality rates in patients with GIAD were higher for weekend compared with weekday hospital admissions.MethodsWe performed a retrospective study using the National Inpatient Sample database from 2000 to 2011 including inpatients with an International Classification of Diseases, Ninth Revision, Clinical Modification code for gastrointestinal GIAD (code 537.82 or 537.83). We assessed rates of delayed endoscopy (examinations performed >24 hours after admission), intensive care unit (ICU) admissions, and in-hospital mortality rates. Bivariate and multivariate logistic regression analyses were performed to identify risk factors for mortality.ResultsThere were 85,971 discharges for GIAD between 2000 and 2011, of which 69,984 (81%) were weekday hospital admissions and 15,987 (19%) were weekend admissions. Patients with weekend versus weekday admissions were more likely to undergo delayed endoscopic examination (35% vs 26%, P ≤ .0001). Mortality rates were higher for patients with weekend admissions (2% vs 1%, P = .0002). The adjusted odds ratio (aOR) for inpatient mortality associated with weekend admissions was elevated (2.4; 95% confidence interval [CI], 1.5-3.9; P = .0005). Rates of delayed endoscopic examinations were lower in patients with higher socioeconomic status (aOR = 0.77; 95% CI, 0.68-0.88). ICU admission rates were higher for weekend compared with weekday admissions (8% vs 6%, P = .004). The presence of a delayed endoscopic examination was associated with an increased length of stay of 1.3 days (95% CI, 1.2-1.4 days).ConclusionsWeekend admissions for angiodysplasia were associated with higher odds of mortality, ICU admissions, higher rates of delayed endoscopic procedures, longer lengths of stay, and higher hospital charges.Copyright © 2016 American Society for Gastrointestinal Endoscopy.
