This data relate to close on four million Discovery Health Administered Medical Scheme members' clinical health records, and span elements as wide-ranging as disease registrations, hospital and medicine authorization requests, healthcare provider billing and diagnosis-related information.
We create measurement tools that that make sense of this complex data landscape. This includes designing, creating and maintaining clinical algorithms and classification systems that explain healthcare demand and supply patterns, automating regular reports, and addressing new and unique business questions in a customised, creative way.

CEO Discovery Health
Dr Ryan Noach
The Discovery Group was founded by actuaries, and we have grown to become one of the largest employers of actuaries in the country. Everything in our business is measured. And, we use the data generated to strategise, stay ahead of trends and plan accordingly, continually trying to extract the maximal value proposition for our services. During the COVID-19 period, our Discovery Health Intelligence Team performed ongoing studies and analyses of multiple aspects of the pandemic, with the sole focus of understanding the depth and breadth of we could do to enhance and protect lives - our customers' lives and society at large. COVID-19 was a novel disease. So, every insight generated was useful in better understanding the pandemic, and aligning our services and solutions to the context at hand. Over time, our Health Intelligence team broadened its investigations to include a host of health-related themes. We are excited to openly share our analyses and findings with the public through the Discovery Health Insights Hub, and to continue to provide a credible and robust set of analytics, both to enhance dialogue and provide rational considered material for further consideration.
