Deeper Integration of Chronic Care and Digital Health:What’s Next for NYCHH and Welldoc®

At Fall Forum 2021, Dr. Karyn Singer, MD MPH, AVP of Chronic Disease and Prevention from NYCHH and Keith Reynolds, COO at Welldoc, discussed their journey integrating digital health into chronic care at one of America’s largest public health systems.


In 2018, New York City Health and Hospital System estimated that half of their patients with diabetes couldn’t achieve their glycemic targets. This was especially problematic as they serve a diverse and vulnerable population, disproportionately affected by type 2 diabetes.

The Objective: Discover an effective and scalable solution that could easily integrate into patients’ daily lives.

The Plan: Develop a pilot program with Welldoc to see if the right digital solution could help patients self-manage their blood glucose levels.

Phase 1 Success

Patients used the BlueStar® app to track and record their blood glucose levels. Using the patient’s information, BlueStar was able to deliver individual guidance, weekly reports, and reminders, articles, healthy recipes, and videos.

The results

Beginning in December 2018, patients with poorly-controlled diabetes (n=273) were enrolled in the BlueStar®* app pilot program. Participants were eligible if they had a diagnosis of type 2 diabetes, an A1C ≥ 9%, and monitored over 6 months.

  • 1.1 average reduction in A1C Levels¹

  • >50% once-a-week user engagement1

  • 82% of patients recorded blood glucose levels¹

  • 40% of users accessed the Spanish-version of BlueStar2

Phase 2 Underway

As a result of the success sustained in the initial pilot, Phase 2 has seen an expansion in location: NYCCH has added three additional hospitals and their respective patient populations.

Key components of Phase 2:

  • Further personalizing each patient’s engagement throughout their health journey

  • Further promoting the program to other patients who already use a smartphone

  • Further helping care teams leverage digital health data to support the right interventions, conversations, and clinical decisions

  • Further understanding the needs of patient populations with digital health data

Phase 2 and Beyond

Results from the expanded Phase 2 pilot are already promising. Based on current outcomes, it appears that there is a strong opportunity to expand the program to other locations – as well as broadening the reach of digital health to pre-diabetes and management of comorbidities such as hypertension and heart failure, as supported by Welldoc.

There may also be an opportunity to leverage Welldoc’s member outreach capability to increase awareness, enrollment, and most importantly, impact.
