中国中西部城市医院经皮冠状动脉介入治疗十年趋势——China PEACE回顾性CathPCI研究结果

Ten Year Trend of Percutaneous Coronary Intervention in Central-western Urban Hospitals of China——Results From China PEACE-Retrospective CathPCI Study

目的:评价2001年至2011年间中国中西部城市医院行经皮冠状动脉介入治疗(PCI)患者的临床特征、治疗模式和院内结局的变化趋势。方法:使用"冠心病医疗结果评价和临床转化(China PEACE)研究"——回顾性冠脉造影和介入治疗(CathPCI)研究(以下简称China PEACE回顾性CathPCI研究)的数据,分析两阶段随机抽样获得的2001年、2006年和2011年有代表性的中西部城市医院PCI患者的临床信息,并对每年度的数据分别进行加权计算。结果:我国中西部地区26家城市医院的2152份PCI病历纳入分析。2001年至2011年PCI患者的住院例数增加46倍。与2001年相比,2011年行PCI治疗的患者中女性、年龄≥80岁、合并糖尿病和高脂血症以及有PCI病史者的比例更高。经桡动脉途径手术的比例由2001年的3.5%增至2011年的87.6%(趋势P<0.01);药物洗脱支架的应用比例由2001年的16.4%增至2011年的95.7%(趋势P<0.01),其中大部分为国产支架。直接PCI患者病历中到院时间和球囊扩张时间的记录率均不足2%。住院时长由2001年的中位数18天降至2011年的12天(趋势P<0.01)。10年间院内死亡率无显著变化,任何原因出血和穿刺部位出血的发生率呈下降趋势(趋势P<0.01)。结论:2001年至2011年我国中西部城市医院PCI病例数迅猛增长,患者的临床特点和治疗模式发生了显著变化,但在医疗质量方面尚存在改善空间。

Objective：To assess the trends in clinical characteristics, treatment, and outcomes for hospitalized patients undergoing percutaneous coronary intervention（PCI） in central-western urban hospitals of China in 2001, 2006 and 2011.Methods： We used a 2-stage, random sampling strategy to create a Chinese central-western urban hospital representative sample of 2152 patients undergoing PCI at 26 hospitals in China PEACE- retrospective CathPCI study and calculated the weighted data of clinical information in each year.Results： Between 2001 and 2011, the admission rate for PCI increased by 46 folds. Compared with 2001, the patients undergoing PCI were more likely to be female, older than 80 years, and to have history of diabetes, dyslipidemia and PCI in 2011. The proportion of trans-radial PCIs increased from 3.5% in 2001 to 87.6% in 2011（P_（trend） 0.0001）; the proportion of drug eluting stents（DES） among all the implanted stents increased from 16.4% in 2001 to 95.7% in 2011（P_（trend） 0.0001）, largely due to increased use of domestic DES. Less than 5% of medical record of admission for PCI documented door time and balloon time. The median length of stay decreased from 13 days in 2001 to 10 days in 2011（P_（trend） 0.0001）. In-hospital mortality did not change significantly, but both any bleeding and access bleeding events were decreased significantly over time（P_（trend） 0.05）. Conclusion： There has been a rapid increase in the volume and significant change in treatment patterns of PCI over the 10-year period from 2001 to 2011 in Chinese central-western urban hospitals. We identified quality gaps that represent opportunities to improve medical care.
