Risk of comorbidities and outcomes in patients with lower gastrointestinal bleeding - a nationwide study.

ABSTRACT: The impact of comorbidities on outcomes of patients with lower gastrointestinal bleeding (LGIB) remains unknown.Investigate the prevalence of comorbidities and impact on outcomes of patients with LGIB.The Nationwide Inpatient Sample 2010 was used to identify patients who had a primary discharge diagnosis of LGIB based on International Classification of Diseases, the 9th revision, clinical modification codes. The presence of comorbid illness was assessed using the Elixhauser index. Logistic regression models were used to assess the contributions of the individual Elixhauser comorbidities to predict in-hospital mortality.A total of 58,296 discharges with LGIB were identified. The overall mortality was 2.3 %. Among the patients who underwent colonoscopy, 17.3 % of patients had therapeutic intervention. As the number of comorbidities increased (i.e., 0, 1, 2, or >3), mortality increased (1.7, 2.0, 2.4, and 2.4 %, respectively). The mortality rate was highest in patients >65 years of age (2.7 %). Patients >65 years of age with two or more comorbidities had a mortality rate of 5 % as compared to 2.6 % in those with less than two comorbidities. Congestive heart failure (odds ratio, 1.67 [95 % confidence interval, 1.48-1.95]), liver disease (2.64 [1.83-3.80]), renal failure (1.99 [1.70-2.33]), and weight loss (2.66 [2.27-3.12]) were associated with a significant increase in mortality rate. Comorbidities increased hospital stay and costs.Comorbidities were associated with increased the risk of mortality and health care utilization in patients with LGIB. Identification of comorbidities and development of risk-adjustment tools may improve the outcome of patients with LGIB.

Project description:Background Performing colonoscopy within 24 h of presentation to the hospital is the accepted standard of care for patients with an acute lower gastrointestinal bleed (LGIB). Previous studies have failed to demonstrate the benefit of early colonoscopy (EC) on mortality. In this study, we wanted to see if there was a change in inpatient deaths (primary outcome), length of stay (LOS), and hospitalization charges (TOTCHG) (secondary outcomes) with EC compared to previous studies. Methods Adults diagnosed with LGIB were identified using the International Classification of Disease 10th Revision codes from the National Inpatient Sample database for 2016 to 2019. EC was defined as the procedure performed within 24 h of hospitalization. Delayed colonoscopy (DC) was defined as a procedure performed after 24 h of presentation. The patient population was divided into EC and DC groups, and the effects of several covariates on outcomes were measured using binary logistic and multivariate regression analysis. Inverse probability treatment weighting (IPTW) was performed to adjust for confounding covariates. Results There were 1,549,065 cases diagnosed with LGIB, of which 285,165 cases (18.4%) received a colonoscopy. A total of 107,045 (6.9%) patients received early colonoscopies. EC was associated with decreased inpatient deaths (0.9% in EC, and 1.4% in DC, P < 0.001). However, upon IPTW, this difference was not present. EC was associated with a decreased LOS (median 3 days vs. 5 days, P < 0.001) and TOTCHG (median $32,037 vs. $44,092, P < 0.001). Weekend admissions (WA) were associated with fewer EC (31.6% in WA, and 39.5% in non-WA, P < 0.001). WA did not affect inpatient deaths. Conclusions EC was not associated with decreased inpatient deaths. There was no difference in endoscopic interventions in both EC and DC groups. The difference in inpatient deaths observed between the two groups was not evident upon adjusting the results for confounders. EC was associated with a decreased LOS, and TOTCHG in patients with LGIB.

Project description:Background & aimsGuidelines recommend colonoscopy evaluation within 24 hours of presentation or admission in patients with high-risk or severe acute lower gastrointestinal bleeding (LGIB). Meta-analyses of the timing of colonoscopy have relied primarily on observational studies that had major potential for bias. We performed a systematic review of randomized trials to determine optimal timing of colonoscopy for patients hospitalized with acute LGIB.MethodsWe searched publication databases through July 2019 and abstracts from gastroenterology meetings through November 2019 for randomized trials of patients with acute LGIB or hematochezia. We searched for studies that compared early colonoscopy (within 24 hours) with elective colonoscopy beyond 24 hours and/or other diagnostic tests. Our primary outcome was further bleeding, defined as persistent or recurrent bleeding after index examination. Secondary outcomes included mortality, diagnostic yield (identifying source of bleeding), endoscopic intervention, and any primary hemostatic intervention (endoscopic, surgical, or interventional radiologic). We performed dual independent review, data extraction, and risk of bias assessments. We performed the meta-analysis using a random-effects model.ResultsOur final analysis included data from 4 randomized trials. Further bleeding was not decreased among patients who received early vs later, elective colonoscopy (relative risk [RR] for further bleeding with early colonoscopy, 1.57; 95% CI. 0.74-3.31). We did not find significant differences in the secondary outcomes of mortality (RR, 0.93; 95% CI, 0.05-17.21), diagnostic yield (RR, 1.09; 95% CI, 0.99-1.21), endoscopic intervention (RR, 1.53; 95% CI, 0.67-3.48), or any primary hemostatic intervention (RR, 1.33; 95% CI, 0.92-1.92).ConclusionsIn a meta-analysis of randomized trials, we found that colonoscopy within 24 hours does not reduce further bleeding or mortality in patients hospitalized with acute LGIB. Based on these findings, patients hospitalized with acute LGIB do not generally require early colonoscopy.
