Hospital discharge data from all acute care hospitals in Maryland were used to examine trends in hospitalized head injury incidence and outcome by severity. From 1979 to 1986, discharge rates increased by 3.4/100,000 per year; the largest percent increase was for more severe injuries. Discharge rates increased the most for adults ages 15-24 and ages 75+ but declined for children ages 0-4. Coinciding with the increase in head injury discharges was a decrease in the hospital case-fatality rate across all severity groups.
来自马里兰州所有急症医院的出院数据被用于研究按严重程度划分的住院头部损伤发病率和转归趋势。1979年至1986年,出院率以每年3.4/10万的速度增长;增长百分比最大的是较严重损伤。15 - 24岁的成年人和75岁及以上的成年人出院率增长最多,而0 - 4岁儿童的出院率则下降。与头部损伤出院人数增加同时出现的是,所有严重程度组的医院病死率都有所下降。
