Drug-pricing program improved prostate cancer treatment adherence

April 1, 2024
Patients from socially vulnerable areas were more likely to stick with oral medications when treated at a hospital participating in 340B program.

Prostate cancer patients receiving care at hospitals that are part of a special drug-pricing program were more likely to stick to their prescription drug therapy than patients at other hospitals, according to a study from researchers at the University of Michigan’s Rogel Cancer Center and Institute for Healthcare Policy and Innovation.

The 340B Drug Pricing Program is a federal program that requires the pharmaceutical industry to provide a discount on the cost of drugs to participating hospitals who serve a disproportionate number of Medicare and Medicaid patients. The program was started to enable hospitals to stretch scarce resources, reach more patients and provide more comprehensive services.

The team looked back at a 20% sample of Medicare beneficiaries diagnosed with advanced prostate cancer and assessed who was treated with these targeted therapies at a hospital-based program. They identified 2,237 men treated at 340B-participating hospitals and 1,100 treated at non-participating hospitals.

They then looked at the social vulnerability index, a measure developed by the U.S. Centers for Disease Control and Prevention that characterizes socioeconomic, racial and household characteristics at the community-level. They found that patients from areas with greater social vulnerability were less likely to use the oral drugs. There was no difference in use between 340B and non-340B hospitals.

However, patients receiving treatment at 340B hospitals were more likely to continue treatment. The researchers saw that in non-340B hospitals, as social vulnerability increased, adherence dropped. But in 340B hospitals, adherence remained flat regardless of social vulnerability. Results were published in Cancer.
