Reducing Medication Abandonment; Improving Retention in Care

In early 2021, Riley Johnson, the community co-chair for Florida’s Comprehensive Planning Network, and Kim Molnar, the Director of The AIDS Institute’s Center for Convening and Planning, reached out to me to discuss a more and more pressing issue the state’s pharmacies were noticing: medications patients weren’t picking up. Their primary concern was understanding the scope of the problem and developing interventions appropriate to ensure the state’s Ryan White clients were getting the medications they needed. How does this problem fit into the state’s Integrated Plan and Ending the HIV Epidemic efforts?

The question of scope is one highlighted in a recent report from the trade organization known as PhRMA (Pharmaceutical Research and Manufacturers of America). The report focuses on how medication abandonment is a symptom and measure of health equity (or inequity, as is the case). Comparing the rise in high cost-sharing commercial insurance plans and medication abandonment from between 2016 and 2020, there’s a clear association. Not only did medication cost-sharing increase on new brand name medications, the out-of-pocket costs of many existing brand name medications increased and with those rises in costs came a rise in medication abandonment.

Insurers set the prices end-user patients have to pay at the pharmacy counter and increasing these costs effectively allow for these payers to defer expenses on care. When out-of-pocket costs reached $125 at the pharmacy counter, medication abandonment increased from 40% in 2016 to 58% in 2020. Across all prescriptions, medication abandonment only rose by 4% for the same timeframe, from 10% to 14%. It’s important to note these high cost-sharing medication because they’re often those assigned to chronic conditions, like diabetes, HIV, and hypertension, in which generic options aren’t’ as effective, have difficult to manage side effects, or aren’t even available. Indeed, our providers prescribe particular medications because those medications are appropriate to our individual and personal care.

Digging in further, PhRMA recognized an immediate disparity in who was not picking up their medications. On average, Black patients were 7% more likely to abandon new medications than their white peers. The disparity was particularly high among patients seeking pre-exposure prophylaxis for the prevention of HIV (PrEP) with Black patients 41% more likely to abandon a new fill compared to their white counterparts. Similarly, when a medication’s out-of-pocket cost rose to $125 per fill, PrEP again out paced other medication classes with a 34% disparity between Black and white patients. On the issue of income, between patients who earn less than $50,000 per year (lower-income) and those earning more than $100,000 per year (high-income), lower-income patients were 16% more likely to abandon their medications compared to their high-income peers, in an overall analysis.

PhRMA offers a few policy solutions to help overcome the cost-at-the-counter barrier; 1. Sharing the rebate and discount savings offered to pharmacy benefit managers and health insurers by manufacturers directly with the patients, 2. Covering particular medications from “day one” of benefits, rather than requiring a separate pharmacy benefit deductible to paid first, and 3. Ensuring all value of manufacturer patient assistance programs be credited toward patient deductibles, copays, and out-of-pocket maximums. The report also urges investment in better understanding the root causes of medication abandonment, as one of the limitations of the review includes not being able to account for factors like stigma, the effects of racism, education, or other social determinants of health.

In even this brief, yet national, review of medication abandonment, the necessity of intervention is obvious. That last bit, accurately understanding the “why” and offering an opportunity to intervene is exactly why Louisiana’s Ending the HIV Epidemic plan includes improving data sharing agreements and aims to reach beyond Ryan White funded entities to include the state’s Medicaid program and encourages appropriate coordination for the benefit of patients who need some extra help. When a patient has failed to pick up a medication, it’s the first sign a patient may not yet be ready to start a particular therapy or other barriers to care are pressing enough they’re prime to drop out of care. Improving retention in care by utilizing real-time data or software tools to notify an interventionist, be they case managers or peers, when a patient is struggling to pick up their medications would allow for programs to reach-out, identify the particular barrier a patient may be struggling with and empower or assist them in navigating that barrier. Data collected from these engagements is critical to better understanding and actively quantifying various barriers to care and better targeting individual and community wide interventions.

Medication abandonment is but one issue in which creative solutions, better data sharing while appropriately protecting patient data, and thoughtful considerations from the patient perspective can drive meaningful change.
