The Impact of Group Purchasing Organizations on Healthcare-Product Supply Chains
   by Joice Hu, Leroy B. Schwarz, and Nelson A. Uhan
   Krannert School of Management, Purdue University

A 2011 study that utilized game theory to analyze the impact of GPOs on the healthcare supply chain. Findings include: GPOs decrease overall purchasing costs for hospitals and providers, particularly for small providers; if GPOs were removed from the healthcare marketplace, hospitals would pay higher total purchasing costs; GPO contract administrative fees have no effect on the total purchasing costs of any provider, large or small; competition among GPOs in the same market for hospital business likely lowers per-unit prices for hospitals; and many large hospitals are part-owner of their GPO and experience lower per-unit and total purchasing costs as a result.

Group Purchasing Organizations (GPOs) Work to Maintain Access to Product Supply for America’s Health Care Providers
   Research and compilation of findings by Avalere Health

GPOs play a vital role in assisting hospitals to limit the impact of drug shortages and to ensure the least possible disruption to patient care by prompt and safe migration to alternative products, where possible. This study analyzes the role of GPOS; specifically, GPOs track data on drug shortages to stay abreast of the topic, strategize with their members when there is a potential for drug supply disruption, and communicate with manufacturers and distributors to foresee any problems. Moreover, GPOs help their members lessen the exposure to drug shortages by evaluating manufacturer’s reliability when sourcing and awarding contracts and in assisting them to establish best practice purchasing procedures.
