Abstract
Introduction: Poor outcomes of coronavirus disease 2019 (COVID-19) have been linked to diabetes but its relation to pre-infection glycemic control is still unclear.
Methods: To address this question we report here the association between pre-infection HemoglobinA1c (A1C) levels and COVID-19 severity as assessed by need for hospitalization in a cohort of 2068 patients with diabetes tested for COVID-19 in Leumit Health Services, Israel, between February 1 and April 30, 2020. Using the LHS integrated electronic medical records system we were able to collect a large amount of clinical information including age, sex, socioeconomic status, weight, height, body mass index, A1C, prior diagnosis of ischemic heart disease, depression/anxiety, schizophrenia, dementia, hypertension, cerebrovascular accident, congestive heart failure , smoking and chronic lung disease.
Results: Of the patients included in the cohort, 183 (8.85 %) were diagnosed with COVID-19 and 46 were admitted to hospital. More hospitalized patients were female, came from higher socioeconomic background and had a higher baseline A1C. A prior diagnosis of cerebrovascular accident and chronic lung disease conferred an increased risk of hospitalization but not obesity or smoking status. In a multivariate analysis, controlling for multiple prior clinical conditions, the only parameter associated with a significantly increased risk for hospitalization was A1C≥9%.
Conclusion: Using pre-infection glycemic control data we identify A1C as a clear predictor of COVID-19 severity. Pre-infection risk stratification is crucial to successfully manage this disease, efficiently allocate resources and minimize the economic and social burden associated with an undiscriminating approach.
