Diabetes Medication Adherence

Medication Adherence for Diabetes (MAD) is a Part D Star Measure introduced by the Centers for Medicare and Medicaid Services. It ensures diabetic Medicare patients 18 years and older adhere to their prescribed drug therapy. Those who meet the following criteria during the measurement year are part of the measure population:

Denominator
Numerator
Patient has at least 2 non-insulin diabetes medication fills on unique dates of service during the measurement year
Patient in the denominator who has filled their prescription 80% or more of the time they are supposed to be taking the medication

NOTE: Members taking less than 80% of prescribed diabetes medications fail the measure.

Exclusions 

Medicare patients are excluded from this measure if they have any of the following conditions documented: 

  • End-stage renal disease 
  • Hospice care 
  • Prescribed one or more insulin medications

Why is this measure important for providers? 

Medication adherence plays an important role in both patient outcomes and healthcare quality. Better adherence is associated with fewer hospitalizations and lower healthcare costs. Adherence measures also contribute to Medicare star ratings that help plans offer competitive benefits and premiums. 

The following strategies can help providers support medication adherence and improve patient outcomes:

Identify the barriers to medication adherence 

Medication adherence is influenced by a variety of factors. The barriers below are some of the most common challenges that can affect a patient's ability to start, continue, or correctly use prescribed medications:

  • Conflicting information received from a second provider or self-research
  • Financial burden and transportation
  • Health literacy
  • Lack of motivation
  • Not using pharmacy benefit provided or not filling using the insurance benefit
  • Remembering to take medications
  • Unrealistic expectations

Simplify the drug regimen when possible

Consider opportunities to simplify treatment regimens when clinically appropriate. For some patients, reducing the number of daily doses or aligning medication schedules with established routines may help support adherence.

For eligible patients taking immediate-release metformin, an extended-release formulation may reduce dosing frequency and simplify the treatment regimen.

Increase supplies for maintenance medications

When possible, consider changing prescriptions from 30-day supplies to 90- or 180-day supplies for maintenance medications. For members who struggle to conistently go in to refill their medications, Intermountain home delivery pharmacy services are available at no addition cost.
