Aetna, a CVS Health business, announced the launch of Attain, a unique health experience designed by Aetna in collaboration with Apple.

Using  an Apple Watch, the Attain app will provide Aetna members personalized goals, track their daily activity levels, recommend healthy actions, and ultimately reward them for taking these actions to improve their well-being. Reward opportunities include the ability for eligible users to earn their Apple Watch through their participation in the program.

This launch builds on the 2016 collaboration between Aetna and Apple in which 90 percent of participants reported a health benefit from their use of Apple Watch.

The Attain app claims to be the first of its kind – designed specifically to offer users a personalized experience that combines their health history with the power of the Apple Watch to help them achieve better health and well-being.

After users have joined Attain, they will have the additional option to share their Attain program data and health history with Apple, enabling Apple and Aetna to collaborate, and over time, continue to improve the Attain experience. Through analytics and machine learning, the collaboration will lead to new features for Attain, offering more personalized recommendations designed to give greater context and decrease barriers to health care.

The developers say user privacy and data security are at the heart of Attain. A completely voluntary program, members determine what information they want to share and can discontinue using Attain at any time. All Attain health data is encrypted on the device, in transit, and on Aetna and Apple’s servers, where it will be stored in a highly secure environment using industry-leading practices fully in compliance with HIPAA.

Information from this program will not be used for underwriting, premium or coverage decisions.

Health history data is tightly regulated by the U.S. government, and Apple and Aetna had to enter into what is known as a business associate agreement in order for Aetna to share it with the Apple. Access to regulated data is necessary for some of the functions of the app, such as recommending age-appropriate exercise or a lower-cost option for scheduled lab tests or MRI imaging tests.

The Attain rewards platform builds off a program developed by Vitality Group, a model that has demonstrated that incentives linked to the Apple Watch are associated with increased, sustained activity. A recent study from RAND corporation found an average 34 percent increase in activity levels for participants using the rewards platform incorporated in Attain with Apple Watch, compared to those without these incentives – leading to an additional 4.8 days of activity per month.
