BACKGROUND There is limited evidence on the comparative performance of private and public healthcare. Our aim was to compare outcomes following surgery for lumbar disc herniation (LDH) in private versus public hospitals. METHODS Data were obtained from the Norwegian registry for spine surgery. Primary outcome was change in Oswestry disability index (ODI) 1 year after surgery. Secondary endpoints were quality of life (EuroQol EQ-5D), back and leg pain, complications, and duration of surgery and hospital stays. RESULTS Among 5221 patients, 1728 in the private group and 3493 in the public group, 3624 (69.4%) completed 1-year follow-up. In the private group, mean improvement in ODI was 28.8 points vs 32.3 points in the public group (mean difference - 3.5, 95% CI - 5.0 to - 1.9; P for equivalence < 0.001). Equivalence was confirmed in a propensity-matched cohort and following mixed linear model analyses. There were differences in mean change between the groups for EQ-5D (mean difference - 0.05, 95% CI - 0.08 to - 0.02; P = 0.002) and back pain (mean difference - 0.2, 95% CI - 0.2, - 0.4 to - 0.004; P = 0.046), but after propensity matching, the groups did not differ. No difference was found between the two groups for leg pain. Complication rates was lower in the private group (4.5% vs 7.2%; P < 0.001), but after propensity matching, there was no difference. Patients operated in private clinics had shorter duration of surgery (48.4 vs 61.8 min) and hospital stay (0.7 vs 2.2 days). CONCLUSION At 1 year, the effectiveness of surgery for LDH was equivalent in private and public hospitals.

私立与公立医院腰椎间盘突出症的手术:比较实用的研究。

背景技术关于私人和公共医疗保健的比较表现的证据有限。我们的目的是比较私立和公立医院腰椎间盘突出症(LDH)手术后的结局。方法数据从挪威脊柱外科登记处获得。主要结果是术后1年Oswestry残疾指数(ODI)发生变化。次要终点为生活质量(EuroQol EQ-5D),背部和腿部疼痛,并发症,手术时间和住院时间。结果在5221例患者中,私人组1728例,公共组3493例,完成了1年随访的3624例(69.4%)。在私人组中,ODI的平均改善为28.8点,而在公共组中为32.3点(均值-3.5,95%CI-5.0至-1.9;等价<0.001,P)。在倾向匹配的队列中以及在混合线性模型分析之后确认了等效性。EQ-5D组的平均变化(均差-0.05,95%CI-0.08至-0.02; P = 0.002)和背痛(均差-0.2,95%CI-0.2,-0.4至-0.4)之间存在差异-0.004; P = 0.046),但在倾向匹配之后,两组没有差异。两组在腿痛方面没有发现差异。私人组的并发症发生率较低(4.5%比7.2%; P <0.001),但倾向匹配后没有差异。在私人诊所进行手术的患者手术时间较短(48.4 vs 61.8 min),住院时间较短(0.7 vs 2.2 2.2天)。结论在1年时,私立和公立医院的LDH手术效果相当。EQ-5D组的平均变化(均差-0.05,95%CI-0.08至-0.02; P = 0.002)和背痛(均差-0.2,95%CI-0.2,-0.4至-0.4)之间存在差异-0.004; P = 0.046),但在倾向匹配之后,两组没有差异。两组在腿痛方面没有发现差异。私人组的并发症发生率较低(4.5%比7.2%; P <0.001),但倾向匹配后没有差异。在私人诊所进行手术的患者手术时间较短(48.4 vs 61.8 min),住院时间较短(0.7 vs 2.2 2.2天)。结论在1年时,私立和公立医院的LDH手术效果相当。EQ-5D组的平均变化(均差-0.05,95%CI-0.08至-0.02; P = 0.002)和背痛(均差-0.2,95%CI-0.2,-0.4至-0.4)之间存在差异-0.004; P = 0.046),但在倾向匹配之后,两组没有差异。两组在腿痛方面没有发现差异。私人组的并发症发生率较低(4.5%比7.2%; P <0.001),但倾向匹配后没有差异。在私人诊所进行手术的患者手术时间较短(48.4 vs 61.8 min),住院时间较短(0.7 vs 2.2 2.2天)。结论在1年时,私立和公立医院的LDH手术效果相当。95%CI-0.2,-0.4至-0.004; P = 0.046),但在倾向匹配之后,两组没有差异。两组在腿痛方面没有发现差异。私人组的并发症发生率较低(4.5%比7.2%; P <0.001),但倾向匹配后没有差异。在私人诊所进行手术的患者手术时间较短(48.4 vs 61.8 min),住院时间较短(0.7 vs 2.2 2.2天)。结论在1年时,私立和公立医院的LDH手术效果相当。95%CI-0.2,-0.4至-0.004; P = 0.046),但在倾向匹配之后,两组没有差异。两组在腿痛方面没有发现差异。私人组的并发症发生率较低(4.5%比7.2%; P <0.001),但倾向匹配后没有差异。在私人诊所进行手术的患者手术时间较短(48.4 vs 61.8 min),住院时间较短(0.7 vs 2.2 2.2天)。结论在1年时,私立和公立医院的LDH手术效果相当。在私人诊所进行手术的患者手术时间较短(48.4 vs 61.8 min),住院时间较短(0.7 vs 2.2 2.2天)。结论在1年时,私立和公立医院的LDH手术效果相当。在私人诊所进行手术的患者手术时间较短(48.4 vs 61.8 min),住院时间较短(0.7 vs 2.2 2.2天)。结论在1年时,私立和公立医院的LDH手术效果相当。
