A cross-sectional survey of 96 people living independently with spinal cord injuries (SCI) in Eastern Massachusetts shows that 57% had been hospitalized at least once in the year before the survey. Sample means were 1.0 admissions and 16.0 days/person/year. Eight percent of the sample (eight persons) accounted for 22% of admissions and 59% of total hospital days. For those hospitalized, the mean was 1.7 admissions and 45.1 days/person/year. Mean length-of-stay was 34.7 days/admission. Multiple regression analysis shows that three variables appear to be independently related to increased numbers of admissions: self-assessment of health; place of residence; and age (younger respondents at higher risk). One variable is independently associated with total days of hospitalization: leaving home at least once daily (as opposed to less frequently) is associated with lower risk. There were no statistically significant relationships between either numbers of hospitalizations or total days hospitalized and ADL or IADL status, education, employment, medical insurance, household composition, gender, age at onset of disability, time since onset of disability, substance use (alcohol, cannabis, or tobacco), level of SCI lesion, or social supports.
对马萨诸塞州东部96名独立生活的脊髓损伤（SCI）患者进行的一项横断面调查显示，57%的患者在调查前一年至少住院一次。样本均值为每人每年1.0次入院和16.0天。样本中的8%（8人）占入院人数的22%和总住院天数的59%。对于那些住院的患者，均值为每人每年1.7次入院和45.1天。平均住院时间为每次入院34.7天。多元回归分析表明，有三个变量似乎与入院次数增加独立相关：健康自评；居住地；以及年龄（年轻受访者风险更高）。一个变量与总住院天数独立相关：每天至少外出一次（与不那么频繁外出相比）与较低风险相关。住院次数或总住院天数与日常生活活动（ADL）或工具性日常生活活动（IADL）状态、教育程度、就业情况、医疗保险、家庭构成、性别、残疾发病年龄、残疾发病后的时间、物质使用（酒精、大麻或烟草）、脊髓损伤病变水平或社会支持之间均无统计学上的显著关系。
