    Abstract:
    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. RESULTS: The annual pediatric admits correlated with the number of operations (383) done from 11 pm to 7 am (P < .001). The probability of operation within 30 minutes of arrival varies with the number of admits and the percent of penetrating vs blunt injuries. This likely number of operations from 11 pm to 7 am beginning within 30 minutes of patient arrival would be 3.45, 4.21, and 4.95 for TCs admitting 150, 250, and 350 injured children per year, respectively. The probability that 2 rooms would be occupied simultaneously is 0.074 and 0.109 for centers with 160 and 260 pediatric trauma admissions, respectively. CONCLUSION: Trauma centers performing less than 6 pediatric trauma operations per year from 11 pm to 7 am could conserve resources by using an on-call operating room team.
