A Well being Affiairs Forefront article by DiGiorgio (2023) argues the 340B has outlived its functions. He writes:
By mandating that drug firms give a big low cost to lined entities, the vast majority of that are hospitals with disproportionate share or crucial entry designations, the 340B program was supposed to offer a monetary buffer for establishments such because the one the place I work. Nevertheless, the 340B program has turn out to be gamed by giant firms to extend income. It’s not serving its authentic intent.
This system has grown quickly amongst hospitals that serve wealthier affected person populations. 340B hospitals are increasing into extra prosperous neighborhoods, and they’re conscious of payer combine as they transfer into areas with fewer publicly insured sufferers. 340B establishments usually tend to keep away from counties with decrease earnings ranges and extra uninsured sufferers. Whereas Rep. Waxman argues that these revenues are getting used to extend service strains for low-income sufferers, the proof recommend that 340B hospitals didn’t enhance take care of underserved populations or enhance their charges of uncompensated care. There are various reforms that might protect safety-net funding whereas curbing abuses of the 340B system
One key piece of proof DiGriogio cites is a paper by Mulligan et al. (2021). This research discover strategic conduct amongst hospitals. Hospitals that recieve disproportionate share hospitals (DSH) funds are eligible for 340B if their DSH adjustment–a measure that identifies hospitals that deal with a disproportionate share of low earnings Medicare or Medicaid sufferers–is above 11.75%. Mulligan and co-authors used information from Healthcare Price Report Data System (HCRIS) to look at if hospitals are adjusting their DSH to realize eligibility. As a result of investor-owned hospitals aren’t eliigble for 340B, one would count on no strategic conduct from these hospitals. The authors use a McCrary density checks to evaluate whether or not the noticed distinction in density of hospitals just under and above the 11.75% threshold was considerably bigger than what could be anticipated by probability alone. The authors discover that:
In 2014–2016, the variety of hospitals will increase by 41% simply above the 340B eligibility threshold. McCrary density checks discovered this enhance to be statistically important throughout a variety of bandwidths in 2014–2016 (p < 0.01)…We discovered no comparable change amongst hospitals ineligible for the 340B program. These information are in keeping with the speculation that some hospitals modify their DSH to realize 340B eligibility.
