Controlled diagnostic studies have established the prevalence of cervical facet joint pain to range from 36% to 67% based on the criterion standard of ≥ 80% pain relief. Treatment of cervical facet joint pain has been described with Level II evidence of effectiveness for therapeutic facet joint nerve blocks and radiofrequency neurotomy and with no significant evidence for intraarticular injections. However, there have not been any cost effectiveness or cost utility analysis studies performed in managing chronic neck pain with or without headaches with cervical facet joint interventions. Cost utility analysis based on the results of a double-blind, randomized, controlled trial of cervical therapeutic medial branch blocks in managing chronic neck pain. To assess cost utility of therapeutic cervical medial branch blocks in managing chronic neck pain. A randomized trial was conducted in a specialty referral private practice interventional pain management center in the United States. This trial assessed the clinical effectiveness of therapeutic cervical medial branch blocks with or without steroids for an established diagnosis of cervical facet joint pain by means of controlled diagnostic blocks. Cost utility analysis was performed with direct payment data for the procedures for a total of 120 patients over a period of 2 years from this trial based on reimbursement rates of 2016. The payment data provided direct procedural costs without inclusion of drug treatments. An additional 40% was added to procedural costs with multiplication of a factor of 1.67 to provide estimated total costs including direct and indirect costs, based on highly regarded surgical literature. Outcome measures included significant improvement defined as at least a 50% improvement with reduction in pain and disability status with a combined 50% or more reduction in pain in Neck Disability Index (NDI) scores. The results showed direct procedural costs per one-year improvement in quality adjusted life year (QALY) of United States Dollar (USD) of $2,552, and overall costs of USD $4,261. Overall, each patient on average received 5.7 ± 2.2 procedures over a period of 2 years. Average significant improvement per procedure was 15.6 ± 12.3 weeks and average significant improvement in 2 years per patient was 86.0 ± 24.6 weeks. The limitations of this cost utility analysis are that data are based on a single center evaluation. Only costs of therapeutic interventional procedures and physician visits were included, with extrapolation of indirect costs. The cost utility analysis of therapeutic cervical medial branch blocks in the treatment of chronic neck pain non-responsive to conservative management demonstrated clinical effectiveness and cost utility at USD $4,261 per one year of QALY.
已有的对照诊断研究显示,根据 80%以上疼痛缓解的标准,颈椎关节突关节痛的患病率为 36%至 67%。对于颈椎关节突关节痛的治疗,有二级证据证明治疗性关节突神经阻滞和射频神经切断术有效,而关节内注射则没有明显的证据。然而,对于伴有或不伴有头痛的慢性颈痛患者,应用颈椎关节突关节介入治疗的成本效益或成本效用分析研究尚未进行。本研究基于一项双盲、随机、对照的颈椎治疗性内侧支阻滞治疗慢性颈痛的临床试验结果,旨在评估治疗性颈椎内侧支阻滞治疗慢性颈痛的成本效用。
这是一项在美国一家专业转诊私立介入疼痛管理中心进行的随机试验。该试验通过对照诊断性阻滞,评估了治疗性颈椎内侧支阻滞联合或不联合类固醇治疗已确诊的颈椎关节突关节痛的临床疗效。成本效用分析基于该试验中 120 名患者的 2 年随访期内的直接支付数据,采用 2016 年的报销率进行计算。支付数据提供了不包括药物治疗的直接手术费用。根据备受推崇的外科文献,将手术费用乘以 1.67 的系数,再加上 40%的间接费用,以提供包括直接和间接费用在内的估计总成本。
主要结果包括定义为疼痛和残疾状态至少改善 50%,且颈痛指数(NDI)评分疼痛至少降低 50%的显著改善。结果显示,每提高一年质量调整生命年(QALY)的直接手术成本为 2552 美元,总成本为 4261 美元。总体而言,每位患者在 2 年内平均接受 5.7±2.2 次治疗。每次治疗的平均显著改善时间为 15.6±12.3 周,2 年内每位患者的平均显著改善时间为 86.0±24.6 周。
这项成本效用分析的局限性在于数据基于单中心评估。仅包括治疗性介入治疗程序和医生就诊的费用,间接费用的推断。对于治疗性颈椎内侧支阻滞治疗对保守治疗无反应的慢性颈痛的成本效用分析显示,在每 QALY 4261 美元的情况下,具有临床有效性和成本效用。
