Who drives patient enrollment in 2026 treatment adherence programs?

In metabolic health, the Diabetologist is generally considered the natural owner of a Patient Support Program, the specialist with the largest patient volume and the default target for cross therapy areas enrollment strategies. Our data confirms they still lead on total volume.

Looking at data from another angle, Cardiologists are enrolling patients at a 3.7% higher rate per doctor than Diabetologists.

Diabetologists bring high volume and steady engagement, Cardiologists bring lower total volume but faster enrollment per doctor. 

Why Cardiologists matter more than their numbers suggest?

Cardiologists are increasingly initiating metabolic therapies to protect cardiovascular health, not just managing complications after the fact.

For them, the platform functions less as an add-on and more as a risk-management tool for patients they may see less often than a Diabetologist would.

The specialty that identifies the treatment need is not always the specialty that sees the patient most frequently.

An effective adherence strategy needs to work across the entire patient journey, not around a single point of care.

The bigger picture: Cross-therapeutic by design 

Collectively, these cross-therapeutic specialists along with others, such as Endocrinologists and Internal Medicine, now make up 72% of the entire active HCP base in our programs.

What this means for adherence strategies? 

1. Build for scale with Diabetologists

They remain essential for reaching large patient populations and maintaining consistent engagement.

2. Unlock the velocity of Cardiologists

A smaller HCP population does not mean a smaller opportunity. Their higher enrollment rate per doctor deserves dedicated engagement strategies.

3. Design for the cross-therapeutic journey

Patients move between specialists. Your adherence platform should reflect that reality.

4. Measure more than total enrollment

Total enrollment is important, but enrollment per active doctor reveals high-performing specialties that may otherwise be underestimated.
