Which Patients with Mild Acute Pancreatitis Require Prolonged Hospitalization?
Clinical and Translational Gastroenterology 2017 December 8
OBJECTIVES: In our experience, a subset of mild acute pancreatitis (AP) patients, as defined by the Revised Atlanta Classification, has longer than expected hospitalization. Our aims are to report the prevalence of patients with mild AP who have a prolonged length of stay (LOS), evaluate the etiology, thoroughly phenotype, and finally compare this subset to those with expected LOS.
METHODS: Patients admitted with AP from 2003 to 2015 were prospectively enrolled into this cohort study. LOS ≥8 days was considered as prolonged LOS. Data on demographics, clinical and laboratory variables, management, and outcomes was both prospectively and retrospectively collected. Continuous variables were compared using the nonparametric t-test (Wilcoxon's test) and categorical variables using the Pearson's χ2 test.
RESULTS: Among 231 enrolled mild AP patients, 46 (20%) had a prolonged LOS (≥8 days). The main determinants of prolonged LOS included ongoing pancreatitis-related symptoms (n=31, 67.4%) and performance of cholecystectomy (n=11, 23.9%). When compared to patients with expected LOS (<8 days, n=185), patients with prolonged LOS due to ongoing symptoms (n=31) were more likely to have systemic inflammatory response syndrome at 48 h from admission (37% vs. 13.4%, P<0.001), a prolonged fasting period (6.6 vs. 2.8 days, P<0.001), and need for nutritional support (30% vs. 1.6%, P<0.001).
CONCLUSIONS: About 20% of patients with mild AP have a longer than expected hospital stay, mostly attributed to ongoing pancreatitis-related symptoms. An early decision (at 72 h) for enteral nutrition support in these patients needs to be explored so as to shorten hospitalization and reduce cost of care.
