The number of trauma admissions, types of injury, and reasons for temporary closure were studied. Trauma patients admitted numbered 1120 in 1991, 989 in 1992, and 1164 in 1993; blunt trauma accounted for 77 percent, 74 percent, and 80 percent, whereas penetrating trauma accounted for 23 percent, 26 percent, and 20 percent of the admissions by year, respectively. A mean of 81 percent of the blunt trauma studies were for head injuries. The trauma center closed for a total of 260 hours in 1991, 211 hours in 1992, and 240 hours during 1993. Of the total hours closed, the unavailability of computed tomography (CT) scanning due to mechanical reasons was the leading cause for closure, accounting for 59 percent of hours closed. Other reasons for closure included operating (OR) unavailability (33%), acute care beds full (3.4%), blood bank stock shortage (1.4%), insufficient OR nursing teams (0.6%), unavailability of anesthesiologists (0.5%), unavailability of surgical team (1.4%), and hospital water problems (1.4%). It is concluded that designated major trauma centers may need two available CT scanners if they have a greater than 75 percent blunt trauma admission rate, or greater than 500 blunt trauma patient admissions.
对创伤入院人数、损伤类型及临时关闭原因进行了研究。1991年创伤患者入院人数为1120人，1992年为989人，1993年为1164人；钝器伤分别占各年入院人数的77%、74%和80%，而穿透伤分别占23%、26%和20%。钝器伤研究中平均81%为头部损伤。创伤中心在1991年共关闭260小时，1992年关闭211小时，1993年关闭240小时。在关闭的总时长中，因机械原因导致计算机断层扫描（CT）无法使用是关闭的主要原因，占关闭时长的59%。其他关闭原因包括手术室（OR）无法使用（33%）、急症护理床位满员（3.4%）、血库库存短缺（1.4%）、手术室护理团队不足（0.6%）、麻醉医生无法到位（0.5%）、手术团队无法到位（1.4%）以及医院用水问题（1.4%）。得出的结论是，如果指定的主要创伤中心钝器伤入院率高于75%或钝器伤患者入院人数超过500人，可能需要两台可用的CT扫描仪。
