Examining a Common Disease with Unknown Etiology: Trends in Epidemiology and Surgical Management of Appendicitis in California, 1995–2009

Abstract

This is the largest epidemiological study of appendicitis to our knowledge in recent years. Incidence has increased over time and is higher in the summer months. Whites and Hispanics have higher rates of appendicitis, but Hispanics and Asians and patients with non-private insurance, have higher odds of perforation. Surgical management of perforated appendicitis has decreased over time. It is unknown why the incidence has increased, displays seasonality, and varies by race.
