Diabetes hospitalization in Peking Union Medical College Hospital from 1995 to 2009 / 中华临床营养杂志

ABSTRACT

Objective To analyze the hospitalization rates of diabetic patients in different departments in different years and compare the differences in hospitalization costs, length of stay, and mortality between diabetic and non-diabetic patients. Methods The clinical data of hospitalized patients from 1995 to 2009 in different departments of Peking Union Medical College Hospital were retrospectively analyzed. Patients were divided into three groups by calendar period (every five years) and into four groups by ages. Results A total of 500 523 patients were enrolled in this study. From 1995 to 2009, the hospitalization rates of diabetic patients increased from 2.85% to 7.65% , especially among patients who were treated in the departments of cardiology, ophthalmology,and vascular surgery. In 2009, the hospitalization rates of diabetic patients in the three departments were 29.36% , 24. 51% , and 21.25 % , respectively. The length of hospital stay was significantly longer among diabetic patients than among non-diabetic patients (P ＜ 0. 001). The total hospital costs were also significantly higher among diabetic patients than among non-diabetic patients in all the period and age groups (P ＜ 0.01 or P ＜0.001)except in 2000-2004 group and 2005 - 2009 group in 0 - 18 years group (P ＞0. 05). The hospital cost per day in diabetic patients was significantly lower than that in non-diabetic patients in all the period and age groups (P ＜ 0. 05, P ＜ 0. 01 or P ＜ 0. 001)except in 1995-1999 group in over 65 years group (P ＞ 0.05). The mortality rate of diabetic patients in the 1995-2004 in 0-18 years group was zero, and the mortality rates were not significantly different between diabetic patients and non-diabetic patients in 2005 -2009 group in 0-18 years group (P ＞0.05), and were significantly higher in diabetic patients than in non-diabetic patients in all other period and age groups (P ＜0.01 or P ＜ 0. 001). Conclusions Diabetic inpatients tend to have a longer hospital stay, higher hospitalization rate, higher hospital costs, and higher mortality rates. A hospital-wide diabetes management mode should be developed to optimize its treatment.
