Background: Diabetes is known to confer increased risk for infections. Coronavirus disease-19 (COVID-19) has caused significant morbidity and mortality worldwide and in India. Diabetes mellitus (DM) and related comorbidities have a significant impact on clinical presentation and outcomes. Diabetic patients are at a higher risk of developing the severe form of COVID-19. Increased severity of COVID-19 in diabetic patients could be attributed to many factors. Limited data is available about diabetes characteristics in hospitalized patients with COVID-19 and its outcome from India. Hence the present study was carried out to study the outcome of COVID-19 infection among diabetic patients admitted in a tertiary care hospital.

Methods: It was a retrospective cross-sectional study conducted during March 2020 to October 2022 in a tertiary care hospital. Data was obtained from the electronic and written records of 3240 covid-19 patients admitted. Data was collected from medical records that included age, gender, symptoms, comorbid conditions, admission to the intensive care unit (ICU), number of hospitalization days, recovery and mortality.

Results: Total 3240 patients were admitted, out of this 37% were females and 13.9% were diabetics with mean age of 58 years. The rates of ICU admission and days of hospitalization was significantly higher among diabetic patients with COVID-19 than non- diabetics. Further the mortality was also higher among them.

Conclusion: People with diabetes with COVID-19 are at a greater risk of worse prognosis and mortality. Careful assessment of the many components that contribute to poor prognosis with COVID-19 in patients with diabetes might represent the best.
