PURPOSE: Enteral nutrition is associated with improved outcomes in acute pancreatitis (AP), but previous studies have not focused on critically-ill patients. Our purpose was to determine the association between nutritional support and infectious complications in ICU-admitted patients with AP.

METHODS: A retrospective analysis of patients with AP admitted in ICUs of 127 US hospitals from the eICU Collaborative were included. Patients were classified by type (initial and any use) of nutritional support they received: none (NN); oral (ON); enteral (EN); and parenteral nutrition (PN).

RESULTS: 925 patients were identified. Length of stay was longer in the initial PN group (PN 21.3 ± 15.4 d, EN 19.1 ± 20.1 d, ON 8 ± 7.1 d, NN 6.6 ± 6.3 d, p < 0.001) and mortality was more common in the initial EN group (EN 16.7%, PN 8.9%, ON 2.7%, NN 10.9%, p < 0.001). Multivariate analysis found any EN use to be associated with infections (OR 2.12, 95% CI: 1.13-3.98, p = 0.019) and pneumonias (OR 2.04, 95% CI: 1.04-4.03, p = 0.039).

CONCLUSION: EN was associated with an increased risk for pneumonias and overall infections in critically-ill patients with AP. More studies are needed to assess optimal nutritional approaches in critically-ill AP patients and patients who do not tolerate EN.
