Pharmacy Benefit Management Companies: Do They Create Value in the US Healthcare System?

Area of Science:

• Health Economics
• Pharmaceutical Policy
• Healthcare Management

Background:

• Pharmacy benefit management companies (PBMs) operate within the US healthcare system, influencing drug pricing and coverage.
• PBMs aggregate covered lives, granting them significant negotiating power with pharmaceutical manufacturers and providers.
• Their functions, including formulary design and network management, impact prescription drug costs and access.

Purpose of the Study:

• To analyze the role and impact of PBMs in the US healthcare system.
• To evaluate the potential of PBMs to lower drug prices and promote rational prescribing.
• To examine the challenges PBMs face in managing pharmacy benefits amidst rising costs and high-deductible health plans.

Main Methods:

• The study reviews the functions and market position of PBMs.
• It analyzes the interplay between PBMs, benefit design, clinical processes, and overall healthcare system dynamics.
• The impact of factors like prescribing patterns, patient adherence, and fraud on PBM effectiveness is considered.

Main Results:

• PBMs possess the potential to reduce drug prices and improve prescribing through negotiation and intermediation.
• However, potential savings can be undermined by irrational prescribing, poor adherence, ineffective formularies, and fraud, waste, and abuse.
• Rising drug costs and high-deductible plans present significant challenges to PBMs' goal of affordable pharmacy benefits.

Conclusions:

• The actual value and cost-effectiveness of PBMs remain debatable due to the opacity of their rebate and incentive contracts.
• Realizing the full potential of PBMs requires a holistic approach addressing system-wide factors beyond individual PBM components.
• Further transparency in PBM contracts is needed to ascertain their contribution to restraining drug prices.
