Mathematical modeling to define optimum operating room staffing for pediatric patients in trauma centers.

Background: Adult trauma centers (TCs) in the United States may be verified with an on-call operating room team if the performance improvement program shows no adverse outcome. Using queuing and simulation methodology, this study attempts to add a volume guideline for injured children.

Methods: Data from 63 verified TCs identified demographic factors including specific information regarding the first pediatric trauma-related operation done between 11 pm and 7 am each month for 1 year.
