Abstract

Goal: The goal of this study was to evaluate the inpatient mortality risk among geriatric patients with inflammatory bowel disease (IBD).

Background: The challenges of caring for elderly patients with IBD will increase with the aging of the US population. Given the complications of hospitalization, we set to examine if elderly patients age older than 65 were at higher risk of mortality.

Materials and methods: All patients with ulcerative colitis (UC) or Crohn's disease (CD) in the National Inpatient Sample (NIS) from 2016 and 2017 as the primary diagnosis or secondary diagnosis with an IBD-related cause of admission were included. Outcomes for patients aged above 65 were compared with below 65 using multivariable survey-adjusted regression. CD and UC were analyzed separately.

Results: In 2016-2017, there were an estimated 162,800 admissions for CD and related complications compared with 96,450 for UC. In total, 30% of UC and 20% of CD admissions were geriatric. Geriatric status was associated with higher odds of mortality for CD [odds ratio (OR)=3.47, 95% confidence interval (CI): 2.72-4.44] and UC (OR=2.75, 95% CI: 2.16-3.49) after adjustment for comorbidities, admission type, hospital type, inpatient surgery, and IBD subtype. The cause of death was ∼80% infectious in both CD and UC in all groups. An average of 0.19 days (95% CI: 0.05-0.34) and $2467 (95% CI: 545-4388) increase was seen for geriatric CD patients. No significant change was seen for UC.

Conclusions: Age over 65 was independently associated with higher odds of death in both UC and CD patients, even after appropriate adjustment. Further research is needed to optimize care for this growing patient population.
