Factors Associated With Length of Stay and 30-Day Revisits in Pediatric Acute Pancreatitis.

OBJECTIVE: The objective of the study was to identify factors associated with length of stay (LOS) and 30-day hospital revisit for patients hospitalized with acute pancreatitis (AP).

METHOD: Multicenter, retrospective cohort study using the Pediatric Health Information System database. Multilevel linear and logistic regression was used to identify factors independently associated with the primary outcome variables of LOS and 30-day hospital revisit in children aged 1 and 18 years discharged with a primary discharge diagnosis of AP from participating hospitals between 2008 and 2013.

RESULTS: For the 7693 discharges, median LOS was 4 days (interquartile range 3-7 days) and 30-day revisit rate 17.6% (n = 1356). Discharges were primarily girls (55%), Caucasian (46%), and 6 years old or older (85%). On multilevel regression, factors independently associated with both longer LOS and higher revisit odds included malignant and gastrointestinal complex chronic conditions (CCCs) and total parenteral nutrition use while hospitalized. Male gender was associated with both lower LOS (adjusted length of stay = -0.6 days, 95% confidence interval [CI] = -0.8 to -0.4) and decreased revisit odds (aOR 0.85; 95% CI = 0.74 to 0.97). Hispanic ethnicity was associated with increased LOS (adjusted length of stay = +0.8 days, 95% CI = +0.5 to +1.1), but no change in revisit odds.

CONCLUSIONS: Certain demographic and clinical factors, including gender, ethnicity, and type of CCC, were independently associated with LOS and risk of 30-day hospital revisit for pediatric AP. Children with malignant and gastrointestinal CCCs who require total parenteral nutrition are at highest risk for both longer LOS and hospital revisit when admitted with AP. These patient populations may benefit from intensive care coordination when hospitalized for AP.
