ABSTRACT

Objective To understand the variation of the motality and death causes for diabetic inpatients in West China Hospital(WCH) during 1996～2004. Methods First,the amount of diabetic inpatients(14670) and died persons (9597)were got each year by computer search system of our hospital from 1996 to 2004,and the case code of died diabetic subjects (842)were obtained.Then,those medical records were investigated and reviewed in details to get useful information.The motality,death causes and its constituent ratio of dead diabetic inpatients were analysed. Data input and analysis were conducted using the tool Epidate3.0,packages SPSS13 and SAS8.0. Results There were totally 14760 inpatients and 842 deaths who were suffered from DM during 1996-2004.The mortality rate was 5.74% and the standardized mortality rate was 5.37%.Tumor was the first cause of deaths (22.3%),followed by infection(15%),fatal cardiovascular events(14.4%),cerebrovascular events(12.3%).Diabetic nephropathy(DN)(6.3%) took the 6th place just after COPD(8%).There were 9269 deaths in the hospital in total(≥15 years old) during 1996-2004 while DM patients contributed 9.08% to them.The proportion of diabetic patients among the total deaths kept increasing every year(χ2=71.9070,P<0.01). Conclusions The mortality proportion of diabetic inpatients among the total deaths in West China Hospital from 1996 to 2004 is increasing every year.It needs to pay more attention to the main death cause of tumor in diabetic patients
