全髋关节置换术不同假体材料的成本效果分析

Cost-effectiveness analysis of different artificial prostheses in total hip replacement

目的分析全髋关节置换术不同假体材料的成本效果。方法根据不同人工假体材料,200例全髋关节置换术患者分为骨水泥-金属对聚乙烯型(A组,13例)、骨水泥-陶瓷对聚乙烯型(B组,13例)、生物-金属对聚乙烯型(C组,48例)、生物-陶瓷对聚乙烯型(D组,80例)和生物-陶瓷对陶瓷型(E组,46例),比较手术指标及并发症,分析不同假体材料的成本效果。结果 A、B组红细胞输血量多于C、D、E组(P<0.01)。五组术后并发症发生率比较无统计学差异(P>0.05)。A、C组单位效果所需成本最小(P<0.05)。结论在以上5种假体材料中,骨水泥-金属对聚乙烯型和生物-金属对聚乙烯型人工假体有较好的成本效果比。

Objective To analyze the cost-effectiveness of different artificial prostheses in total hip replacement（THR）.Methods Based on different artificial prostheses materials,200 patients underwent THR were divided into groups of A（bone cement-metal polyethylene type,13cases）,B（bone cement-ceramic polyethylene type,13cases）,C（biological-metal polyethylene type,48cases）,D（biological-ceramic polyethylene type,80cases）and E（biological-ceramic to ceramic type,46cases）.The indications for operation and complications were compared and the cost-effectiveness of different artificial prostheses was analyzed.Results The amount of red blood cell transfusion was more in groups of A and B than that in groups of C,D and E（P〈0.01）.There were no significant differences in postoperative complications among five groups（P〉0.05）.The cost-effectiveness analysis showed that the less costs in groups of A and C were needed for unit effectiveness（P〈0.05）.Conclusion Among five artificial prostheses mentioned above,bone cement-metal polyethylene type and biologicalmetal polyethylene type of artificial prosthesis have better cost-effectiveness ratio.
