Using the KDIGO criteria, any patient presenting with a creatinine of 1.5 times the baseline or that had an increase in creatinine of 0.3mg/dL in 48 hours was diagnosed with AKI. Pregnant patients, patients with end-stage renal disease (ESRD), and patients with a history of renal transplant were excluded.Results: The incidence of AKI in COVID-19 patients was 39% (608), and the mortality rate was 58.2% (354). Of the 254 survivors, 74.8% recovered. Moreover, 42.6% (259) of patients with AKI were admitted to the ICU. Twenty-six of our patients received hemodialysis during admission. There was a statistically significant association between AKI and age, race, hypertension (HTN), diabetes mellitus (DM), hepatitis C (HCV), congestive heart failure (CHF), CKD, patient outcome, and days spent in the hospital. Of the 608 patients with AKI, 294 (48.4%), 185 (30.4%) and 129 (21.2%) had AKI stage 1, 2 and 3, respectively.Conclusion: Early resource planning is necessary when admitting COVID-19 patients. Nephrology should be consulted early, and measures should be in place to optimize outpatient follow-up in the nephrology clinic. Lastly, the use of nephrotoxic agents should be carefully considered and, if possible, avoided from the time of admission in patients with COVID-19.Keywords: acute kidney injury, AKI, COVID-19, hemodialysis, chronic kidney disease, CKD
