Abstract
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.
