Introduction:
We developed a service to identify potential study participants through electronic medical records and deliver study invitations through patient portals.
Methods:
The service was piloted in a cohort study that used multiple recruitment methods.
Results:
Patient portal messages were sent to 1303 individuals and the enrollment rate was 10% (n=127). The patient portal enrollment rate was significantly higher than email and post mail (4%) strategies.
Conclusion:
Patient portal messaging was an effective recruitment strategy.
