Ongoing Pilot Project Finding Up to 24% Increase in Medication Refills

According to the Centers for Disease Control and Prevention (CDC), 82% of U.S. adults take at least one medication and 29% take five or more, yet studies show that as much as 50% of medications are not taken as prescribed and up to 30% are never filled.[1], [2], [3] Poor medication adherence can cause additional health complications and is estimated to cost the healthcare system nearly $300 billion annually.[4] Medication adherence is a complex behavioral issue that can be heavily influenced by social factors (or social determinants of health). To improve adherence, it is critical to understand the underlying reasons that a person is not taking a treatment as prescribed and then help address those reasons or barriers to optimize medication use and achieve better health.

To address this multifaceted issue, Health Dialog initiated a pilot project to determine if medication adherence could be improved by proactively identifying a member’s most likely adherence barrier(s) using the Pathways Engine, our machine learning and artificial intelligence platform, and providing personalized interventions to address the predicted barrier(s). While the pilot project is still underway, we are already seeing promising results, with up to a 24% increase in medication refills.

Aiming for Improved Medication Adherence

The ongoing pilot is being incorporated into our existing Adherence Intervention Management (AIM) solution. AIM helps increase medication adherence by providing outreach to identified members taking diabetes, hypertension and cholesterol medications who may be at risk for nonadherence. The program uses the Pathways Engine to identify which members to target.

The Pathways Engine utilizes over 600 data points, including medical (when available) and prescription claims and socio-economic factors, to identify members at risk for nonadherence who are most likely to be responsive to interventions, as well as their preferred communication method. With the pilot project, we’re taking it a step further and using the Pathways Engine to identify members of two of our long-standing Medicare Part D clients who are likely to have one or more of the following barriers:

  • Transportation
  • Depression
  • Physical limitation
  • Alzheimer’s/dementia
  • Likely to forget to take their medication

Identified members are being randomly divided into two groups for outreach: the personalization group and the control group. Our Care Navigators, who conduct the outreach, are being informed of the potential barrier(s) for the personalization group and given talking points for addressing the issues and possible solutions to share with the member. In the control group, the member and the Care Navigator work together to identify the potential barrier(s), absent the benefit of artificial intelligence.

To date, the results have shown up to a 24% increase in prescription refills for the personalization group compared to the control group, depending on the particular barrier. While the pilot project is ongoing, we believe it demonstrates that knowing about potential issues with medication adherence from the start allows Care Navigators to focus discussions and help members overcome their personal medication adherence barriers. We will present more details and the full results of this study in a white paper in early September.
