The impact of COVID-19 on Diabetic Ketoacidosis patients

Background and aim: Describe the prevalence/outcomes of Diabetic Ketoacidosis (DKA) patients comparing pre- (March-April 2019) and pandemic (March-April 2020) periods. Methods: Retrospective cohort of admitted pandemic DKA/COVID-19+ patients comparing prevalence/outcomes to pre-pandemic DKA patients that takes place in Eleven hospitals of New York City Health & Hospitals. Our included participants during the pandemic period were admitted COVID-19+ patients (>18 years) and during the pre-pandemic period were admissions (>18 years) selected through the medical record. We excluded transfers during both periods. The intervention was COVID-19+ by PCR testing. The main outcome measured was mortality during the index hospitalization and secondary outcomes were demographics, medical histories and triage vital signs, and laboratory tests. Definition of DKA: Beta-Hydroxybutyrate (BHBA) (>0.4 mmol/L) and bicarbonate (<15 mmol/L) or pH (<7.3). Results: Demographics and past medical histories were similar during the pre-pandemic (n = 6938) vs. pandemic (n = 7962) periods. DKA prevalence was greater during pandemic (3.14%, 2.66-3.68) vs. pre-pandemic period ( 0.72%, 0.54-0.95) (p > 0.001). DKA/COVID-19+ mortality rates were greater (46.3% (38.4-54.3) vs. pre-pandemic period (18%, 8.6-31.4) (p < 0.001). Surviving vs. non-surviving DKA/COVID-19+ patients had more severe DKA with lower bicarbonates by 2.7 mmol/L (1.0-4.5) (p < 0.001) and higher both Anion Gaps by 3.0 mmol/L (0.2-6.3) and BHBA by 2.1 mmol/L (1.2-3.1) (p < 0.001). Conclusions: COVID-19 increased the prevalence of DKA with higher mortality rates secondary to COVID-19 severity, not DKA. We suggest DKA screening all COVID-19+ patients and prioritizing ICU DKA/COVID-19+ with low oxygen saturation, blood pressures, or renal insufficiency. (c) 2022 Diabetes India.

Automated summary

This study compared the prevalence and outcomes of Diabetic Ketoacidosis (DKA) patients before and during the pandemic, revealing that the prevalence of DKA increased significantly during the COVID-19 pandemic period, with higher mortality rates among DKA/COVID-19+ patients. It is recommended to screen all COVID-19+ patients for DKA and prioritize ICU treatment for DKA/COVID-19+ patients with certain risk factors.
