Abstract

Abstract : Objectives: Little is known about the factors that affect the length of stay (LOS) of children hospitalized for perforated appendicitis. The objective of this study was to identify clinical and demographic factors associated with a prolonged LOS (PLOS) in children with perforated appendicitis. Methods: A retrospective cohort study was conducted using the records of 197 children 0 to 17 years old with perforated appendicitis. The children were hospitalized at one of two teaching hospitals located in El Paso, Texas, and were discharged between January 2008 and January 2014. PLOS was defined as an LOS greater than the 75th percentile value in our patient cohort, which was 7 days. An initial log-binomial regression model failed to converge, and hence logistic regression was used to calculate adjusted incidence odds ratios (OR) for PLOS, 95% confidence intervals, P values, and a receiver operating characteristic curve. The best subset method was used to identify predictors for inclusion in the final model. Results: The overall risk of PLOS was 23.4% (46/197). Approximately 76% of the children who experienced PLOS and 94% of those who did not have PLOS were Hispanic. After adjusting for insurance status, presence of an abscess, asthma, consulting interventional radiology, and various antibiotics, Hispanics were less likely than non-Hispanics to experience PLOS (adjusted OR 0.20; P = 0.003). Children whose providers consulted the interventional radiologist had an increased odds of PLOS (adjusted OR 3.64; P = 0.01). Conclusions: Hispanic ethnicity was associated with a lower odds of PLOS, whereas children who required the services of an interventional radiologist were more likely to experience PLOS. Abstract : Appendicitis is among the most frequent surgical emergencies in children. The authors conducted a retrospective cohort study to identify factors that are correlated with a prolonged length of stay in children who were hospitalized for perforated appendicitis.
