The mortality in infectious inpatients with type 2 diabetes compared with non-diabetic population Infection in type 2 diabetes

The aim of the study was to determine the mortality in infectious inpatients with type 2 diabetes mellitus (T2DM) compared with nondiabetic population. A retrospective study was conducted on 13,916 infectious inpatients in The First Hospital of Qinhuangdao. Diabetic types were classified using International classification of Diseases-10. Mortality records were collected. The mortality was higher in patients with T2DM than patients without T2DM (T2DM 4.3% vs non-diabetes 1.7%, chi(2)=59.560, P<.001). In multiple logistic regression analysis, T2DM was an independent risk factor of death in infectious inpatients (OR=1.539, 95% CI: 1.181 similar to 2.006, P=.001). The mortalities between those with T2DM and those without T2DM were stratified by age. The mortalities of patients with T2DM were 0.0% in similar to 39 years, 0.0% in 40 to 49 years, 2.7% in 50 to 59 years, 3.1% in 60 to 69 years, 4.1% in 70 to 79 years and 8.7% in 80 similar to years groups. The mortalities of patients without T2DM were 0.2% in similar to 39 years, 0.1% in 40 to 49 years, 0.6% in 50 to 59 years, 1.0% in 60 to 69 years, 3.1% in 70 to 79 years and 5.9% in 80 similar to years groups. T2DM was an independent risk factor of death only in 60 to 69 years groups (OR=2.323, 95% CI: 1.234 similar to 4.372, P=.009). The increase of mortality appears earlier in patients with T2DM. Infectious inpatients with T2DM are at increased risk of death and brings heavy economic burden to patients, society and government.
