Inpatient Mortality in People With Type 2 Diabetes: A Cross-sectional Study

Abstract

Objective: This study aimed to estimate inpatient mortality rate for diabetes and identify its associated factors. Material(s) and Method(s): This is a cross-sectional study. The population was comprised between January 1 and December 31, 2019 in 32 public hospitals in Portugal, using summary hospital discharge data. We used both the Disease-Related Diagnosis Groups and the Disease Staging. Patients were grouped into survivors and non-survivors, and inpatient mortality was compared using competing event regression. Result(s): A total of 7980 patients were admitted with type 2 diabetes mellitus, there were 747 (10.3%) non-survivors. The advanced age (OR = 1.772;95% CI 1.625-1.932), the stage (3) severity of type 2 diabetes mellitus (OR = 4.301;95% CI 2.564-7.215), comorbid lung, bronchial or mediastinal malignant neoplasm (OR = 5.118;95% CI 2.222-11.788), comorbid bacterial pneumonia (OR = 3.214;95% CI 2.539-4.070), other respiratory system disorders (OR = 2.187;95%CI1.645-2.909),comorbidrhino-,adeno-andcorona-virus infections (OR = 1.680;95% CI 1.135-2.488) were determinants for inpatient mortality. Conclusion(s): Elderly patients with diabetes with micro- and macrovascular complications of the disease, who have bacterial pneumonia and who enter the emergency department are those who have a lower survival rate.
