Businesses that are serious about reducing health care costs — and improving the health and well-being of their employees — should take a serious look at digital therapeutics, which have the potential to provide effective, low-cost ways to prevent and treat chronic diseases and their consequences. Digital therapeutics are technology-based solutions that have a clinical impact on disease comparable to that of a drug. They primarily use consumer-grade technology such as mobile devices, wearable sensors, big data analytics, and behavioral science and can be delivered through web browsers, apps, or in conjunction with medical devices. They can also be deployed in real time and at scale, which is critical for intervention in chronic diseases.
