Opt-in enrollment: patient will be sent a recruitment letter, in which they must call the study team to take part in the study. During that call, the study team will schedule the participant for an intake visit.

Opt-out enrollment: patient will be sent a letter communicating to them that they have been enrolled into a research program at their doctor's office. After 10 days, the study team will contact the opt-out participants to schedule an intake visit.

Every day of the 91 day intervention period participants will be asked to use each of their biometric devices. A daily lottery will be conducted automatically by the study website. Participants must use each of their two devices daily to be eligible for the lottery the following day. Winning lottery numbers will be identified by a fixed-position match between the automatically generated winning number and a participant ID number, which each participant will pick at enrollment.

The primary objective is to obtain preliminary evidence regarding whether or not patients opt-into a research study, as opposed to enrolling by default, will affect participation in the program and the effectiveness of the intervention, among high-risk patients. The primary outcome is to measure enrollment rates. The investigators will also measure participation in the program through device usage.
