    Abstract:
    BACKGROUND: Acute appendicitis is among the most common indications for surgery in children in the Western world. The epidemiology of acute appendicitis in the United States has not been recently analyzed in a population-based cohort study. METHODS: Here, we describe the epidemiology of acute appendicitis in the pediatric population in New England from 2000 to 2006. RESULTS: Our results show that there is clustering of perforated and nonperforated appendicitis by hospital catchment area (Moran I index 0.01 and 0.03, respectively). The overall incidence of nonperforated appendicitis decreased over our study period by 9.7% (P < .05), the proportion of perforated appendicitis did not change significantly over our study period, and there was a 38% decrease in the proportion of negative appendectomies (P < .05). CONCLUSIONS: There were trends toward increased operative volume for pediatric surgeons as well as sharp increases in the use of laparoscopy and early discharge with home health services. Our results demonstrate that the epidemiology, outcomes, and trends in treatment of acute appendicitis continue to change.
