中医药对慢性心力衰竭患者再住院率影响的回顾性研究

Retrospective study of Chinese medicine on rehospitalization rate in chronic heart failure patients

目的探讨中医药对慢性心力衰竭(chronic heart failure,CHF)患者再住院率的影响。方法采集2006年3月至2011年3月望京医院心内科CHF患者的信息,并对经规范治疗缓解出院的CHF患者进行电话随访或预约病人门诊随访。完成数据整理及录入后,应用SPSS统计软件进行数据分析。结果本研究共纳入CHF患者388例,最短随访6个月,最长随访5年半,平均随访3年。半年内再住院者192例,占49.48%。与再住院率相关的Logistic回归分析显示出院后未使用中药能影响CHF患者再住院率;本研究中CHF患者平均住院次数2.8次,其中院外服用中药者平均住院次数1.9次,不服用中药者为3.4次;第2次住院距离首次住院平均间隔时间为183 d,其中院外服用中药者为221 d,不服用中药者为145 d。结论积极规律辨证使用中药能够降低CHF患者的再住院率,减少平均住院次数,延长再住院间隔时间。

Objective To discuss the influence of Chinese medicine on rehospitalization rate of chronic heart failure（ CHF） patients. Methods CHF patients ＇information in cardiovascular department of Wangjing hospital from March 2006 to March 2011 were collected. And telephone follow-up or appointments with outpatient follow-up to patients after standard treatment were carried out. All data were analysed by SPSS software after data reduction and input. Results 388 cases of CHF patients were included in this research,the shortest follow-up period was 6 month,and the longest was five and a half years,the average follow-up period was 3 years. There were 192 cases of rehospitalization within half a year,which accounted for 49. 48%. Logistic regression analysis of rehospitalization rate showed without using Chinese medicine could influence rehospitalization rate. In this study,the average admission times was 2. 8 for CHF patients,the average admission times was 1. 9 for patients taking Chinese medicine out of hospital,and 3. 4 times for patients who didn＇t take Chinese medicine; the period between first and second hospitalization was 183 days in average,the average period was 221 days for patients who were taking Chinese medicine after treatment,and 145 days for patients without taking Chinese medicine after treatment.Conclusions Using Chinese medicine regularly based on syndrome differentiation could reduce rehospitalization rate for CHF patients,as well as decrease average admission times and lengthen the interval time of rehospitalization.
