Assessing the Impact of the 340B Drug Pricing Program: A Scoping Review of the Empirical, Peer-Reviewed Literature. | LitMetric

AI Article Synopsis

  • The 340B Drug Pricing Program significantly impacts the US healthcare system, accounting for about 1% of total spending, and decisions made about it affect safety net services nationwide.
  • A scoping review of existing literature reveals that nonprofit hospitals involved in the program may prioritize financial margins, though evidence of increased community engagement is weak and varies by hospital type.
  • The review encompasses 44 peer-reviewed studies, highlighting common research questions and categorizing the literature based on the motivation behind 340B use and the types of healthcare entities involved.

Article Abstract

Unlabelled: Policy Points The 340B Drug Pricing Program accounts for roughly 1 out of every 100 dollars spent in the $4.3 trillion US health care industry. Decisions affecting the program will have wide-ranging consequences throughout the US safety net. Our scoping review provides a roadmap of the questions being asked about the 340B program and an initial synthesis of the answers. The highest-quality evidence indicates that nonprofit, disproportionate share hospitals may be using the 340B program in margin-motivated ways, with inconsistent evidence for increased safety net engagement; however, this finding is not consistent across other hospital types and public health clinics, which face different incentive structures and reporting requirements.

Context: Despite remarkable growth and relevance of the 340B Drug Pricing Program to current health care practice and policy debate, academic literature examining 340B has lagged. The objectives of this scoping review were to summarize i) common research questions published about 340B, ii) what is empirically known about 340B and its implications, and iii) remaining knowledge gaps, all organized in a way that is informative to practitioners, researchers, and decision makers.

Methods: We conducted a scoping review of the peer-reviewed, empirical 340B literature (database inception to March 2023). We categorized studies by suitability of their design for internal validity, type of covered entity studied, and motivation-by-scope category.

Findings: The final yield included 44 peer-reviewed, empirical studies published between 2003 and 2023. We identified 15 frequently asked research questions in the literature, across 6 categories of inquiry-motivation (margin or mission) and scope (external, covered entity, and care delivery interface). Literature with greatest internal validity leaned toward evidence of margin-motivated behavior at the external environment and covered entity levels, with inconsistent findings supporting mission-motivated behavior at these levels; this was particularly the case among participating disproportionate share hospitals (DSHs). However, included case studies were unanimous in demonstrating positive effects of the 340B program for carrying out a provider's safety net mission.

Conclusions: In our scoping review of the 340B program, the highest-quality evidence indicates nonprofit, DSHs may be using the 340B program in margin-motivated ways, with inconsistent evidence for increased safety net engagement; however, this finding is not consistent across other hospital types and public health clinics, which face different incentive structures and reporting requirements. Future studies should examine heterogeneity by covered entity types (i.e., hospitals vs. public health clinics), characteristics, and time period of 340B enrollment. Our findings provide additional context to current health policy discussion regarding the 340B program.
