Description
Six researchers test email nudges for patient portal sign up in a 2026 trial. Portals help patients manage care, yet sign up rates stay low. The trial ran at one large health system with more than five thousand patients who had fresh lab results.
Patients got one of two emails or none over a fifteen day window. Either email near tripled sign up within a week versus no email. The edge shrank but held through one year, and wording style made no difference. Nudges worked best when lab results were time sensitive. People who signed up after a nudge used the portal later at rates like natural sign ups.
