399. Risk Factors for Mortality in COVID-19 Patients in a Community Teaching Hospital

BACKGROUND: As of May 2020, there were over 190,000 confirmed COVID-19 cases in New York City (NYC) with approximately 13,000 deaths. Previously published literature identified risk factors (advanced age, higher severity of illness and elevated d-dimer) for mortality in a cohort of patients from Wuhan, China and mechanical ventilation in a case series from NYC. Another case series from NYC evaluated clinical outcomes only. There are limited published studies assessing clinical characteristics, outcomes and risk factors for mortality in COVID-19 patients in NYC. The objective of this study was to assess the risk factors for mortality in patients with confirmed COVID-19 infections. METHODS: This study was a single center retrospective case-control at The Brooklyn Hospital Center, a 464-bed community teaching hospital. Adult patients with confirmed COVID-19 infection, who received at least 24 hours of COVID-19 therapy were included. Endpoints assessed were risk factors for mortality in COVID-19 patients, increase in QTc, renal failure or renal replacement therapy, ventricular fibrillation or ventricular tachycardia. Baseline characteristics between survivor and non-survivors were analyzed utilizing Mann-Whitney U test/two-tailed t-tests for continuous data and Chi-square/Fisher’s exact test for categorical data. Univariable and multivariable logistic regression analyses were conducted to identify the risk factors for in-hospital mortality. RESULTS: Two-hundred and eighty six patients were included in this analysis, of whom 97 (33.9%) were non-survivors and 189 (66.1%) patients were survivors. Diabetes and coronary artery disease were more common in non-survivors compared to survivors (p = 0.003 and p < 0.001, respectively). Multivariable logistic regression showed higher in-hospital mortality in patients with advanced age (odds ratio 5.779, 95 % confidence interval 1.369–24.407), vasopressor initiation (OR 28.301, 95 % CI 3.307–242.176), and development of renal failure (OR 30.927, 95 % CI 1.871–511.201). CONCLUSION: Risk factors associated with mortality for COVID-19 patients in a community teaching hospital include advanced age, vasopressor therapy, and development of renal failure.
