The incidence of hospitalization for acute spinal cord injury in the United States from 1970 to 1977 has been calculated using a detailed subsetting of the National Hospital Discharge Survey (HDS). The overall eight-year incidence was 40.1 (SE = 3.8) per million population in the United States. Patients admitted for spinal cord injury were more than twice as likely to be male (male to female ratio = 2.4:1 and spinal cord injury was particularly common in males ages 20-24 (118.3/10(6)) and 25-34 (98.7/10(6). Blacks also appeared to be at twice the risk than whites. Case fatality during hospitalization was 11.2% overall, was 36% more common in males and increased markedly with advanced age with 35.9% of males greater than or equal to 65 years old dying during hospitalization. The HDS data are in general agreement with previous regional studies of incidence and appear to provide a reasonably valid and cost-effective method for monitoring the national incidence of hospitalized spinal cord injury.
利用国家医院出院调查（HDS）的详细子数据集，计算了1970年至1977年美国急性脊髓损伤的住院发病率。美国八年总体发病率为每百万人口40.1（标准误=3.8）。因脊髓损伤入院的患者男性比例是女性的两倍多（男女比例=2.4:1），脊髓损伤在20 - 24岁男性（118.3/10⁶）和25 - 34岁男性（98.7/10⁶）中尤为常见。黑人的患病风险似乎也是白人的两倍。住院期间的病死率总体为11.2%，男性比女性高36%，且随着年龄增长显著增加，65岁及以上男性住院期间的病死率为35.9%。HDS数据与之前关于发病率的区域研究总体一致，似乎为监测全国住院脊髓损伤发病率提供了一种合理有效且具有成本效益的方法。
