Abstract

INTRODUCTION: Diabetes mortality has increased in recent years. In Peru, there are few studies on in-hospital mortality due to type 2 diabetes in the provinces.

OBJECTIVE: To determine factors associated to hospital mortality in patients with diabetes mellitus type 2 in three hospitals from Cusco-Peru.

METHODS: An analytical cross-sectional study was performed. All patients with diabetes mellitus type 2 hospitalized in the city of Cusco during the 2016 were included. Socio-educational and clinical characteristics were evaluated, with "death" as the variable of interest. The crude (cPR) and adjusted (aPR) prevalence ratios were estimated using generalized linear models with Poisson family and log link function, with their respective 95% confidence intervals (95% CI). The values p <0.05 were considered significant.

RESULTS: A total of 153 patients were studied; 33.3% (51) died in the hospital. The mortality rate increased when the following factors were associated: age of the patients increased the mortality rate by one-year increments (aPR: 1.02; CI95%: 1.01-1.03; p<0.001); to have been admitted by the emergency service (aPR: 1.93; CI95%: 1.34-2.77; p<0.001); being a patient who is readmitted to the hospital (aPR: 2.01; CI95%: 1.36-2.98; p<0.001); and patients who have had a metabolic in-hospital complication (aPR: 1.61; CI95%: 1.07-2.43; p=0.024) or renal in-hospital complications (aPR: 1.47; CI95%: 1.30-1.67; p<0.001). Conversely, the mortality rate was reduced when admission was due to a urinary tract infection (aPR: 0.50; CI95%: 0.35-0.72; p<0.001); adjusted by seven variables.

CONCLUSIONS: A third of hospitalized diabetes mellitus type 2 patients died during the study period. Mortality was increased as age rises, patients admitted through emergency rooms, patients who were readmitted to the hospital, and patients who had metabolic or renal complications. Patients admitted for a urinary tract infection had a lower mortality rate.
