Health measurement company Evidation Health and diabetes data firm Tidepool have launched a research program to study real-world data from people with type 1 diabetes.

The T1D Sleep Pilot will develop insights from data generated by continuous glucose monitors and insulin pumps, in addition to sleep and activity trackers from smartphones and other connected sensors. The observational study will explore links between nocturnal hypoglycemia, next-day behavior, sleep patterns, and heart rates in order to contribute to ongoing research on how everyday behavior data and diabetes complications interact.

“Linking real-world data from connected devices with other medical data in virtual studies allows us to measure how behaviors — outside of the doctor’s office or hospital — affect health and impact outcomes,” said Deborah Kilpatrick, CEO of San Mateo, Calif.-based Evidation, in a prepared statement. “Tidepool has done a fantastic job of giving people with diabetes access to their own data, and this effort provides a new opportunity to share everyday data with researchers at scale and enable more people to contribute to diabetes innovation.”

The partnership brings together Evidation’s data platform, which analyzes and processes large-scale sensor and behavior data in clinically meaningful ways, with Tidepool’s device-agnostic consumer software. Nonprofit Tidepool joins a growing list of more than 100 data sources that are linked to Evidation’s platform, including Apple Health, Blue Button, Dexcom, Epic and Fitbit.

“People with diabetes can use their individual data to play a key role in improving health,” said Howard Look, president, CEO & founder of Tidepool, Palo Alto, Calif. “Our study with Evidation gives people with diabetes a new way to share their data with researchers, and contribute to a better understanding of dangerous low blood sugar levels, which can often occur more frequently while sleeping.”

Evidation Health’s  Achievement app has more than 2 million users, the company noted.
