Résumé
Objective:To analyze hospitalization cost of patients with coronary heart disease (CHD) undergoing per-cutaneous coronary intervention (PCI) in recent years and its influencing factors.Methods:Hospitalization cost data of CHD patients undergoing PCI in a hospital of Anhui province from 2012 to 2016 were collected.Changes of hos-pitalization costs and its influencing factors were statistically analyzed.Results:Number of hospitalized CHD pa-tients undergoing PCI gradually rose year by year.From 2012 to 2016,there was significant rise in mean examina-tion fee per time (except 2012 vs.2013),significant reductions in mean medicine fee per time,mean bed fee and other fees (except 2013 vs.2014 ) and mean hospitalization duration per time (except 2012 vs.2013,2014 vs.2015),P＜0.05 or ＜ 0.01.Patients with full public insurance possessed the highest mean hospitalization fee per time.Mean medicine fee per time of male group was significantly higher than that of female group [5368.66 (3831.01,7974.22) RMB vs.5045.16 (3721.97,7308.26) RMB],P＝0.019.Mean treatment fee per time of 50～70 years group was significantly higher than that of ≤50 years group [ (36351.63 (27925.86,47714.41) RMB vs.34622.20 (27296.66,46504.87) RMB],P＝0.024;compared with ≤50 years group and 50～70 years group,there were significant rise in all fees in ＞70 years group,P＜0.05 or ＜0.01.Compared with hospitalization ≤7d group,there were significant rise in all fees in 7～14d group and ＞14d group,and those of ＞14d group were signif-icantly higher than those of 7～14d group,P＝0.001 all.Multifactor linear regression analysis indicated that hospi-talization duration was independent risk factor for hospitalization fee of CHD patients undergoing PCI (β＝0.461,P＝0.001),while insurance way was its independent protective factor (β＝ -0.078,P＝0.001).Conclusion:Eco- nomic burden of CHD inpatients undergoing PCI is still heavy,we must improve theraputic effect,reduce hospital stays,in order to reduce patients′economic burden.
