Abstract Background Coronavirus disease 2019 (COVID‐19) is now the third leading cause of death in the United States. Malnutrition in hospitalized patients increases risk of complications. However, the effect of malnutrition on outcomes in patients infected is unclear. This study aims to identify the impact of malnutrition on mortality and adverse hospital events in patients hospitalized with COVID‐19. Methods This study used data from the National COVID Cohort Collaborative (N3C), a COVID‐19 repository containing harmonized, longitudinal electronic health record data from US health systems. Malnutrition was categorized into three groups based on condition diagnosis: (1) none documented, (2) history of malnutrition, and (3) hospital‐acquired malnutrition. Multivariable logistic regression was performed to determine whether malnutrition was associated with mortality and adverse events, including mechanical ventilation, acute respiratory distress syndrome, extracorporeal membrane oxygenation, and hospital‐acquired pressure injury, in hospitalized patients with COVID‐19. Results Of 343,188 patients hospitalized with COVID‐19, 11,206 had a history of malnutrition and 15,711 had hospital‐acquired malnutrition. After adjustment for potential confounders, odds of mortality were significantly higher in patients with a history of malnutrition (odds ratio [OR], 1.71; 95% confidence interval [CI], 1.63–1.79; P < 0.001) and hospital‐acquired malnutrition (OR, 2.5; 95% CI, 2.4–2.6; P < 0.001). Adjusted odds of adverse hospital events were also significantly elevated in both malnutrition groups. Conclusions Results indicate the risk of mortality and adverse inpatient events in adults with COVID‐19 is significantly higher in patients with malnutrition. Prevention, diagnosis, and treatment of malnutrition could be a key component in improving outcomes in these patients.
