Increased risk of poor clinical outcome in COVID‐19 patients with diabetes mellitus and in‐hospital mortality predictors: A retrospective cohort from a tertiary hospital in Indonesia

Abstract

AbstractAimTo determine association between diabetes in confirmed cases of COVID‐19 and intensive care admission and in‐hospital mortality, evaluate several laboratory parameters as mortality predictor and develop predictors of in‐hospital mortality among diabetics with COVID‐19.MethodsThis retrospective cohort recruited all cases of COVID‐19 hospitalized in Fatmawati General Hospital from March to October 2020. Inclusion criterion was RT‐PCR confirmed cases of COVID‐19 who aged 18 years and older while exclusion criteria were incomplete medical record or cannot be found and pregnant women.ResultsWe enrolled 506 participants to this study with median age of 51 years (IQR:22), female (56.32%), and diabetes (28.46%). Diabetes increased intensive care admission (adjusted OR: 2.57; 95% CI: 3.52–10.43) and in‐hospital mortality (adjusted OR: 2.50; 95% CI: 1.61–3.89). In predicting in‐hospital mortality, ferritin and lactate dehydrogenase offered an acceptable discrimination, AUC: 0.71 (95% CI: 0.62–0.79) and AUC: 0.70 (95% CI: 0.61–0.78), respectively. The optimal cut‐off of predicting mortality for ferritin was 786 g/mL and for LDH was 514.94 u/L. Factors include age above 70 years old, RBGs level on admission above 250 mg/dL or below 140 mg/dL, ferritin level above 786 ng/mL and presence of ARDS increased the odds of mortality among individuals with diabetes.ConclusionsDiabetes increases risk intensive care admission and in hospital mortality in COVID‐19. Multivariate analysis showed that older age, RBG on admission, high ferritin level, presence of ARDS increased the odds of mortality among individuals with diabetes.
