We investigated the pre-operative and one-year post-operative health-related quality of life (HRQoL) outcome by using a Euroqol (EQ-5D) questionnaire in 230 patients who underwent surgery for lumbar spinal stenosis. Data were obtained from the National Swedish Registry for operations on the lumbar spine between 2001 and 2002. We analysed the pre- and postoperative quality of life data, age, gender, smoking habits, pain and walking ability. The relative differences were compared to a Swedish EQ-5D population survey. The mean age of the patients was 66 years, and there were 123 females (53%). Before the operation 62 (27%) of the patients could walk more than 500 m. One year after the operation 150 (65%) were able to walk 500 m or more. The mean EQ-5D score improved from 0.36 to 0.64, and the HRQoL improved in 184 (80%) of the patients. However, they did not reach the level reported by a matched population sample (mean difference 0.18). Women had lower pre- and post-operative EQ-5D scores than men. Severe low back pain was a predictor for a poor outcome.
我们使用欧洲五维健康量表（EQ-5D）问卷，对230例行腰椎管狭窄手术的患者术前及术后一年的健康相关生活质量（HRQoL）结果进行了调查。数据取自2001年至2002年瑞典国家腰椎手术登记处。我们分析了术前及术后的生活质量数据、年龄、性别、吸烟习惯、疼痛和行走能力。将相对差异与瑞典EQ-5D人群调查结果进行了比较。患者的平均年龄为66岁，其中女性123人（53%）。术前，62名（27%）患者能够行走超过500米。术后一年，150名（65%）患者能够行走500米或更远。EQ-5D平均得分从0.36提高到0.64，184名（80%）患者的HRQoL得到改善。然而，他们未达到匹配人群样本报告的水平（平均差异0.18）。女性术前及术后的EQ-5D得分均低于男性。严重的下腰痛是预后不良的一个预测因素。
