This study examined the influence of selected medical, demographic, and epidemiologic variables on the spinal cord injured patient's return to gainful employment 3 years postinjury. Discriminant analysis was the statistical method selected as most appropriate for this study. Utilizing the best combination of predictor variables, the proportion of variance in "working" and "not working" groups explained by discriminant function was 65%. These variables included sex, race, marital status, extent of lesion, preinjury employment history, high Barthel score, incidence of urinary tract infection, and completion of any business or trade school courses. Patients who returned to work were more likely to be (1) young, (2) white, (3) female, and (4) working at the time of injury, and (5) were more likely to have a high Barthel score. Among a validation sample of 34 patients, 71% were correctly classified as employed or unemployed 3 years after injury. While other determinants of vocational rehabilitation undoubtedly exist, individual potential of a given spinal cord injured patient can probably be assessed by means of a relatively small set of predictor variables.
本研究调查了特定的医学、人口统计学和流行病学变量对脊髓损伤患者伤后3年恢复有酬工作的影响。判别分析是被选为最适合本研究的统计方法。利用预测变量的最佳组合,判别函数解释的“工作”组和“未工作”组的方差比例为65%。这些变量包括性别、种族、婚姻状况、损伤程度、伤前就业史、巴氏评分高、尿路感染发生率以及是否完成任何商业或贸易学校课程。恢复工作的患者更有可能(1)年轻,(2)为白人,(3)为女性,(4)在受伤时正在工作,以及(5)巴氏评分更高。在34例患者的验证样本中,71%在伤后3年被正确分类为就业或未就业。虽然职业康复的其他决定因素无疑存在,但通过相对较少的一组预测变量可能可以评估特定脊髓损伤患者的个人潜力。
