Assessing the Impact of myHealth Rewards New Hire Enrollment Emails

The myHealth Rewards wellness program managed by GHP rewards those GHP members who carry their insurance through employment at Geisinger with reduced health insurance premiums over the course of the following year, if members register for the program and have their health measures on file by the enrollment deadline and are then able to meet their health goals by the respective due date. In spite of the potential savings to health plan members and the wellness program's potential to motivate engagement in healthy activities (with consequent improvement in health outcomes), about 23% of eligible existing GHP members did not enroll during the primary 2019 enrollment period, even after receiving promotional email communications and reminders. Therefore, the current study was developed to test whether a revised version of a standard welcome email is more effective than the standard email in increasing myHealth Rewards login and enrollment rates. The standard welcome email is what would typically be sent by GHP to encourage enrollment among new hires; it mentions the benefits of enrollment (maintaining good health and saving money on insurance premiums), the average premium savings, the ease of the registration process, and the deadline for registering and having health measures on file, plus it provides registration steps and hyperlinks for registering and finding free health screenings where health measures can be collected and registered at one convenient time and location. The loss frame email recommends that GHP members not "throw away" a precise monetary amount in savings by not participating and that they can therefore avoid missing out on substantial gains (i.e., savings) by taking action. It is hypothesized that, on average, the loss frame email will increase enrollment compared with the standard email, among this population of new hires for whom this is only the second time that they have been informed about myHealth Rewards. Findings will help inform how best to increase enrollment in a wellness program among health plan members who are new to the system.
