N2 - Objective: The aim of this study was to assess the seasonal variation in emergency general surgery (EGS) admissions. Background: Seasonal variation in medical conditions is well established; however, its impact on EGS cases remains unclear. Methods: The National Inpatient Sample (NIS) database was queried over an 8-year period (2004-2011) for all patients with diagnosis of acute appendicitis, acute cholecystitis, and diverticulitis. Elective admissions were excluded. The following data for each admission were recorded: age, sex, race, admission month, major operative procedure, hospital region, and mortality. Seasons were defined as follows: Spring (March, April, May), Summer (June, July, August), Fall (September, October, November), and Winter (December, January, February). X11 procedure and spectral analysis were performed to confirm seasonal variation. Results: A total of 63,911,033 admission records were evaluated of which 493,569 were appendicitis, 395,838 were cholecystitis, and 412,163 were diverticulitis. Seasonal variation is confirmed in EGS (F=159.12, P
