Circulation:中危重度主动脉瓣狭窄患者经导管与外科主动脉瓣置换的成本效益比较

2018-12-09 xiangting MedSci原创

在中危AS患者中,与SAVR相比,TAVR通过提供更长的质量调整预期寿命和更低的长期成本,在经济上占优势。

对于手术中危的重度主动脉瓣狭窄(AS)患者,经导管主动脉瓣置换术(TAVR)或外科主动脉瓣置换术(SAVR)的2年死亡率和卒中率相似。与SAVR相比,中危患者进行TAVR的成本效益是否更高仍不明确。

在PARTNER-2试验中,2011年至2014年期间3110名中危AS患者接受了TAVR或SAVR治疗。在PARTNER-2A试验中,2032名患者随机接受使用SAPIEN-XT瓣膜(XT-TAVR)的TAVR或SAVR。而PARTNER-S3i登记包括另外1078名使用SAPIEN-3瓣膜进行TAVR的患者(S3- TAVR),与XT-TAVR相比,SAPIEN-3瓣膜的交接轮廓更低并有旨在减少瓣周返流的密封裙。使用测量资源利用率估算手术成本。通过将试验数据与医疗索赔(n=2333)链接,或未链接患者使用线性回归模型(n=682)评估其他成本。在基线、1、12和24个月使用EQ-5D估算健康效用。使用由试验成本、效用和生存数据提供信息的马尔可夫模型,从美国医疗保健系统的角度,以获得的每个质量调整生命年来估算终身成本效益。

尽管TAVR的手术成本比SAVR高约20,000美元,由于TAVR的住院时间短,XT-TAVR指数住院的总成本仅高2888美元(p=0.014),S3-TAVR低4155美元(p<0.001)。与SAVR相比,XT-TAVR(△-$9304; p<0.001)和S3-TAVR(△-$11,377; p<0.001)的随访成本显著较低。在一生的时间中,预计TAVR总成本低8000-10,000美元,质量调整后生存时间延长0.15-0.27年。与SAVR相比,发现XT-TAVR和S3-TAVR分别在84%和97%的自举重复中具有经济优势。

在中危AS患者中,与SAVR相比,TAVR通过提供更长的质量调整预期寿命和更低的长期成本,在经济上占优势。如果长期数据显示TAVR和SAVR的晚期死亡率相当,这些研究结果表明基于临床和经济学考虑,TAVR是中危AS患者的首选治疗策略。
