BACKGROUND: Standardization of antibiotic management of appendicitis in tertiary care pediatric centers has been associated with improved outcomes. Rady Children's Hospital-San Diego implemented an appendicitis clinical pathway in 2005. We evaluated infection-related re-admission risk factors since 2010, when an electronic medical record was established, with the aim to optimize the clinical pathway.
METHODS: Between January 2010 and August 2015, 4725 children with a diagnosis of appendicitis were evaluated for demographic data, pathology diagnoses, culture results, and inpatient and oral step-down antibiotic therapy regimens. From children originally admitted for appendicitis, those who were re-admitted with infection were compared with those who were not re-admitted for infection. The populations were controlled by severity of infection using a pathology-defined appendicitis severity scale: Grade 0, no appendicitis; grade 1, simple acute appendicitis with gross and microscopic evidence of inflammation, but no perforation; grade 2, gangrenous/necrotizing/micro-perforated appendicitis with subserosal or serosal exudate, but no frank or visually appreciated perforation; and grade 3, frank perforation.
RESULTS: Of 4725 children (total population, TP) admitted with a diagnosis of appendicitis, only 199 (4.2%) were re-admitted, with 125 of these admissions for infection (2.65% of the TP). Age, race/ethnicity, language preference, and body mass index were not found to correlate with re-admission for infection. Length of stay significantly differed between the no infection-related re-admission population and infection-related re-admission population (3.02 vs. 4.03 d, p < 0.001). There was a trend toward higher infection-re-admission rates as the pathology grade increased (odds ratio grade 1 vs. grade 3 = 2.28, 95% confidence interval 1.03, 5.03).
CONCLUSIONS: Infection-related re-admission rates for children on the clinical pathway in our institution were infrequent. The greater association of all-cause and infection-related re-admission rates with pathology grade suggest that defining appendicitis by pathology and clinical severity may provide an evidence-based scoring system to support clinical observation in the use and duration of antibiotic therapy.
