目的 观察艾灸治疗膝骨关节炎的临床疗效,并对艾灸疗法进行成本-效果分析。方法 将58例膝骨关节炎患者随机分为艾灸组和电针组,每组29例。每星期治疗3次,连续治疗4星期。观察两组患者治疗前后膝关节功能评分及膝关节疼痛VAS评分,并运用卫生经济学方法进行分析。结果 两组治疗后膝关节功能评分与同组治疗前比较,差异有统计学意义(P〈0.05);电针组优良率为96.6%,艾灸组为75.9%,电针组的总体优良率优于艾灸组(P〈0.05);电针组疼痛总有效率为96.6%,艾灸组为93.1%,两组比较差异无统计学意义(P〉0.05)。艾灸组成本-效果比为6.42,电针组为16.86;电针组的增量成本-效果比为298.55。结论 艾灸及电针均能有效改善患者膝关节功能及缓解膝关节疼痛,艾灸比电针对治疗膝骨关节炎更具有卫生经济学价值。
Objective To observe the clinical efficacy of moxibustion in treating knee osteoarthritis (KO) and analyze its cost-effectiveness. Method Fifty-eight KO patients were randomized into a moxibustion group and an electroacupuncture (EA) group, 29 cases in each group. The two groups were treated 3 times a week, for successive 4 weeks. The knee joint function and Visual Analogue Scale (VAS) for knee joint pain were scored before and after the treatment, and the two groups were analyzed by using health economic methods. Result The knee joint function scores were significantly changed after the treatment in the two groups (P〈0.05); the excellent rate was 96.6% in EA group versus 75.9% in moxibustion group, and the general excellent rate in EA group was markedly higher than that in moxibustion group (P〈0.05); the total effective rate for pain was 93.1% in moxibustion group versus 96.6% in EA group, and the between-group difference was statistically insignificant (P〉0.05). The cost-effectiveness ratio was 6.42 in moxibustion group versus 16.86 in EA group; the incremental cost-effectiveness ratio was 298.55 in EA group. Conclusion Moxibustion and EA both can effectively improve knee joint function and mitigate knee joint pain, while compared with EA, moxibustion has a higher health economic value.
