Key Points Question During emergency department (ED) visits, what proportion of patients actively accesses and views their health information in real time through the patient portal? Findings In this cross-sectional study of 1 280 924 adult patients presenting at 36 EDs across the US between April 5, 2021, and April 4, 2022, 17.4% logged into the patient portal while in the ED. Although patients increasingly used the portal, lower odds of accessing the portal were observed among patients who were male, Black, or without commercial insurance. Meaning These findings suggest opportunities for EDs to promote patient engagement in portal use during ED encounters.
