title: Comparison of pediatric appendicitis outcomes between teaching and nonteaching hospitals.
abstract: OBJECTIVE
  The aim of the study was to determine the outcomes of pediatric appendicitis between a teaching and nonteaching institution.
  
  
  METHODS
  A retrospective review of all patients younger than 18 years treated for appendicitis between 1998 and 2007 was performed. The teaching institution has its own general surgery residency program, and the nonteaching institution has no surgical resident involvement. Both hospitals are part of a larger system and were similar except for resident involvement. Study outcomes included postoperative morbidity and length of hospitalization (LOH). Patients with perforated appendicitis treated nonoperatively were excluded. Data were analyzed using Wilcoxon rank sum test and chi(2) analysis with P < .01 considered significant.
  
  
  RESULTS
  Seven hundred ninety-two patients were treated at the teaching institution (mean age, 10.9 years; 62% male) and 1670 at the nonteaching institution (mean age, 11 years; 61% male). The perforated appendicitis rate was 31% at the teaching institution and 26% at the nonteaching institution (P = .008). Forty-five patients at the teaching institution and 14 at the nonteaching institution with perforated appendicitis were treated nonoperatively and excluded. For nonperforated appendicitis, despite similar rates of postoperative wound infection, abscess drainage, and readmission within 30 days between the 2 institutions, LOH was shorter in the teaching institution (1.4 +/- 1.0 vs 1.8 +/- 1.4 days; P < .0001). For perforated appendicitis, LOH and rates of wound infection, abscess drainage, and readmission within 30 days were similar between the 2 institutions.
  
  
  CONCLUSIONS
  Children with nonperforated appendicitis cared for at a teaching institution had similar postoperative morbidity and shorter LOH compared to a nonteaching institution. In patients with perforated appendicitis, postoperative morbidity and LOH were similar between teaching and nonteaching institutions. Overall, the presence of surgical trainees did not adversely impact on the quality of care for children with appendicitis.
