Disparities Seen in Access to Injectable Biologics

J Dermatolog Treat; ePub 2018 Aug 4; Feng, et al

There are disparities in the availability of injectable biologic-prescribing dermatologists across urban-rural geographic settings in the US, according to a recent study. Researchers used Centers for Medicare and Medicaid Services Medicare Provider Utilization and Payment Data: Part D for 2013-2015. Density of dermatologists who prescribe IB in each US county, represented as number of dermatologists per 100,000 Medicare Part D beneficiaries, was calculated. They found:

  • 2,992 dermatologists (26.3% of dermatologists) prescribed IB.
  • The national density of IB-prescribing dermatologists was 7.22.
  • Only 778 counties (24.8%) have at least 1 IB-prescribing dermatologist.
  • The densities of IB-prescribing dermatologists in metropolitan counties were 8.07-8.12.
  • The densities of IB-prescribing dermatologists were 4.55 and 6.51 for urban populations of >20,000 people adjacent and non-adjacent to metropolitan areas, respectively.
  • Urban counties with populations between 2,500-19,999 and adjacent to a metropolitan area had a density of 2.03 and urban counties with the same population and not adjacent to a metropolitan area had a density of 2.84.
  • Completely rural or urban counties with populations <2,500 people had densities between 2.31-2.35.
