Economies of purchasing group size

Area of Science:

• Health economics
• Pharmaceutical supply chain management

Background:

• Hospital purchasing groups aim to leverage collective bargaining power for cost savings.
• Understanding the relationship between group size and drug pricing is crucial for optimizing procurement strategies.

Purpose of the Study:

• To evaluate the correlation between the size of private hospital purchasing groups and the prices of drug items.
• To determine if factors like group age and location influence drug prices.

Main Methods:

• Analysis of 30 drug line items across 26 private hospital purchasing groups.
• Statistical examination of drug prices in relation to purchasing group size, age, and geographical location.

Main Results:

• A significant negative linear correlation was observed between drug prices and purchasing group size.
• Drug prices were substantially lower in purchasing groups exceeding 10,000 beds.
• No statistically significant relationship was found between drug prices and the age or location of the purchasing groups.

Conclusions:

• The findings support the hypothesis that larger purchasing group size leads to improved contract prices for drugs.
• Optimizing purchasing group size is a viable strategy for reducing pharmaceutical expenditures in hospitals.
