Value is certainly an important dimension when thinking about adoption. But there is also an important constraint to consider. Most of the patients using these patient engagement platform are relatively healthy. They may seek medical attention a few times a year, especially in the primary care context. How do you engage these folks when they are incentives to participate in the platform may be low? How do you demonstrate the value of engagement to someone who is not a regular consumer of health care? These are important questions to think about because the value a relatively young and healthy patient derives from a patient engagement platform may be very different from that of an older patient with a chronic illness.
