The potential for medication errors may increase due to redeployment and reorganization of hospital resources during COVID-19 surges. In this study of patients hospitalized during the first wave of the pandemic, over 90% had at least one prescribing error three months after hospitalization. Intensive care unit admission and a history of chronic obstructive pulmonary disease (COPD) or asthma were risk factors for prescribing errors. Acknowledging and understanding these risk factors allows hospital leadership to target interventions for this population.
