| Abstract: | Background: Patients with inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), are susceptible to protein‐calorie malnutrition secondary to decreased oral intake, malabsorption, and increased metabolic expenditure. In this study, we seek to assess the national frequencies of parenteral nutrition (PN) use among hospitalized patients with IBD and to determine their in‐hospital outcomes. Methods: We analyzed the Nationwide Inpatient Sample from 1988–2006 to determine the frequency of PN usage among patients with UC or CD and to determine their in‐hospital outcomes. A multivariate analysis was performed to identify factors predictive of increased inpatient mortality in this population. Results: From 1988–2006, the annual incidence of PN use among hospitalized patients with CD was 4.29 per 100,000 and among those with UC was 3.80 per 100,000, with trends being relatively stable through the indexed period. The mean length of hospitalization among patients with UC receiving PN was longer compared with patients with CD. Factors predictive of an increased risk for mortality include the following: age >50 years, acute kidney injury, hospital‐acquired pneumonia, Clostridium difficile colitis, prolonged postoperative ileus requiring PN use, pulmonary embolism, malnutrition, and patients with UC relative to CD. Conclusion: Traditionally, patients with CD are at a higher risk for developing malnutrition than patients with UC; however, there is a 2‐fold higher risk for inpatient mortality and a longer length of hospitalization among patients with UC compared with those with CD. This pattern suggests that the use of PN, particularly among patients with UC, serves as a surrogate marker of higher disease acuity and severity. |
