Systemic barriers to access pharmaceutical-sponsored patient assistance programs: Implications for health equity and care delivery at safety-net systems.

107 Background: The rising cost of cancer care, driven in large by oncology drugs, has a significant impact on access to care and contributes to disparities. Pharmaceutical-sponsored patient assistance programs (PAPs) are intended to improve access to care; however, vulnerable populations may experience delays, denials, and treatment interruptions due to complexity of the application process and variable qualifying requirements. We present the impact of a pharmacy-run process to facilitate access to PAPs at a safety-net institution. Methods: Parkland Health (PH) is the safety-net system for Dallas County, which has one of the highest uninsured rates in the US. PH provides free health care to uninsured patients below 250% of the federal poverty income level. Hematology-Oncology patients who are prescribed medications with an existing PAP are identified in a work queue within the EHR. A team of licensed pharmacy technicians - Medication Access Technicians (MATs) - screen patients and if eligible, assist in filling and submitting the application, and follow up with PAP sponsors to ensure timely review and approvals. MATs also monitor refills and assist in PAP renewals to prevent interruptions in care. In this study, we used the average wholesale price to quantify the value of the medications provided through PAPs. Data for 10/01/22 through 09/30/23 are presented here. Results: During the study period, MATs enrolled 548 uninsured patients (90% Hispanic/Black) in PAPs for 38 unique clinic-administered drugs, with an estimated value of 45. 2 million (M), averaging 78, 853 per patient. The highest value and most common clinic-administered PAP drugs were pembrolizumab (96 patients, 8 M) and rituximab (159 patients, 5 M), respectively. For oral agents, MATs enrolled 77 uninsured patients (84% Hispanic/Black) in PAPs for 20 unique medications with an estimated value of 8. 8 M, averaging 114, 711 per patient. Dasatinib was both the most common and highest value PAP oral drug, with 24 patients and an estimated value of 3. 6 M. Of the 38 PAPs for clinic-administered drugs, 25 did not include replacement for dispensed medications. Legal US residence was required by 7 PAPs. The institutional investment by PH (MAT salaries) is estimated at 620, 000 annually. Conclusions: A dedicated team of MATs at PH facilitated access to care through PAP enrollments, reduced treatment interruptions by renewing applications, and reduced institutional drug expenditure, allowing investment in other care delivery initiatives. PAPs are philanthropic by nature and requirements such as legal residence and no-replacement for dispensed medications may negatively impact specific segments of our communities, or result in treatment delays. Advocacy by professional organization and patient groups is warranted to expand access to these potentially life-saving programs.
