Integration of formulary systems with centralized pharmaceutical procurement

Area of Science:

• Health Services Research
• Pharmaceutical Policy
• Public Health Administration

Background:

• The Indian Health Service (IHS) operates numerous hospitals and ambulatory centers, necessitating efficient pharmaceutical management.
• Integrating formularies with group purchasing and supply systems is crucial for cost-effectiveness and quality of care.
• Previous models for multi-facility pharmaceutical management within IHS required evaluation.

Purpose of the Study:

• To describe the integration of formularies with pharmaceutical group purchasing and supply systems within the IHS.
• To present and compare two distinct models of system integration implemented across multiple IHS facilities.
• To evaluate the impact of these integrated systems on drug costs and information on drug use.

Main Methods:

• Two models of integrating formularies and pharmaceutical procurement systems were implemented across IHS facilities.
• Model 1: Separate Pharmacy and Therapeutics (P & T) Committees and formularies per facility, with centralized drug procurement.
• Model 2: A central P & T Committee and formulary for all facilities, supplemented by facility-level P & T Committees.

Main Results:

• Both centralized procurement models led to decreased drug costs across the multifacility systems.
• Integrated systems resulted in increased information regarding drug utilization within the facilities.
• Staff consensus was achieved on selecting high-quality therapeutics in a cost-conscious manner under both models.

Conclusions:

• Centralized pharmaceutical procurement models are effective in reducing costs and enhancing drug use data within the IHS.
• The described integration strategies facilitate consensus on formulary selection for optimal therapeutic and economic outcomes.
• These approaches support the provision of quality therapeutics in a cost-effective environment for diverse healthcare settings.
