Background and Aims
GI 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.
Methods
We 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.
Results
There 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).
Conclusions
Weekend 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.
