MAH performance saw comfortably sustained improvements in 2023, finishing the year nearly 3 percentage points higher than the 5-Star cut point.
Enter Stellus Rx in October, and we see an immediate upturn, completing the year at 5-Stars for MAH …

Focus On
How medication adherence unlocks outcomes, financial performance and patient health
The Challenge
Medicare Advantage plans judge provider performance based, in part, on medication adherence.
Fundamentally, providers know that improved adherence leads to improved patient health. But how can providers influence adherence—and do so in ways that authentically connect the care experience—when, too often:
They lack visibility to which patients are adherent or non-adherent
They lack bandwidth or dedicated expertise to perform patient outreach and follow-up to close adherence gaps
The Solution
We drive 5-Star performance in medication-related quality measures of Medicare Advantage contracts. And we do that again and again because the measures aren't the mission.
Patients' needs and their health remain at the forefront of everything we do. With data as our guide, and pharmacist-led expertise and empathy at the core of every patient interaction, we find the patients who need the right support in the moments that matter ... and guide them to take the next step on their medication journeys.
Above all, patient health is the goal. Predictable, 5-Star performance is simply the output.
Forward-thinking organizations that include …
... trust us as their adherence support for
patient lives and counting.

And here’s the same time period in 2023—a year-over-year improvement of nearly 4 percentage points and comfortably reaching well above 5-Star performance.
Here’s how we reversed the curve in just three months, getting this measure firmly above the 4-Star cut point before then end of 2022.

From trending toward 3-Stars in MAC … to comfortably achieving 5-Stars
Here’s one client’s Medication Adherence for Cholesterol (MAC) numbers before the medical group started work with us in Oct. 2022.
Adherence had already fallen well below the CMS 5-Star cut point … and was on track to fall below the 4-Star cut point by the end of the year.

This performance improvement trend continued in 2023 as well, with MAD performance finishing the year at 90.7%, above the 5-Star threshold.
Not only did Stellus Rx flatten the decline, we elevated adherence almost all the way back to 5-Stars.

And here, the same client’s 2022 results for Medication Adherence for Diabetes (MAD), the third of the three, triple-weighted adherence measures—and the most challenging measure to impact. The entirety of 2022 showed steep decline, dropping below the 4-Star threshold before Stellus Rx intervened.

In August 2023, Stellus Rx stepped in. Working collaboratively with our client, we changed the trajectory, vaulting this organization to 5-Star performance in MAC for 2023.
View from the beginning
After a disappointing 2022 with MAC performance in one health plan, 2023 was beginning to look much the same. This downward trend continued, despite the organization’s use of internal team members to support medication adherence.

Virtually immediate increase in performance changes minds and expectations
A large physician group in Texas saw the same, immediate bend in adherence charts that has turned the organization’s skeptics into vocal believers.
Not only does our model work to produce medication adherence performance, it also drives economic impact.
We analyzed medical claims data for an 11,000-patient cohort. On average, adherent patients in the cohort (as defined by CMS measures) required 30% less in annual healthcare costs compared to their nonadherent peers—results that can be directly tied to clinical marker improvement.

In Our Client’s Words
“We’re certainly not the first physician network to realize that medication adherence is a problem. But no one has figured out how to improve adherence with such consistent results across different geographies, like Stellus Rx has.”
See how the largest network for independent primary care physicians in Texas achieved:
Three straight years of 5-Star (or better) performance in the three triple-weighted medication adherence measures with the Network’s largest payer contract
6-Star performance with this payer in 2022—the first time a group of Catalyst’s size had achieved that feat
Recognition as the highest-performing group in North Texas by multiple payers
