Pharmacy-laboratory interactions: a unique method to control antibiotic costs.

Area of Science:

• Pharmacy and Laboratory Science
• Infectious Disease Management
• Healthcare Economics

Background:

• Inappropriate antibiotic use is a significant issue in hospitals, leading to increased costs and antimicrobial resistance.
• Hospital pharmacists play a crucial role in optimizing antibiotic therapy and reducing unnecessary expenditures.

Purpose of the Study:

• To evaluate a collaborative approach between pharmacy and laboratory departments to improve cost-effective antibiotic therapy.
• To assess the impact of interdepartmental communication on reducing inappropriate antibiotic usage and associated costs.

Main Methods:

• Implementation of a cost-code index on susceptibility reports and suppression of non-formulary antibiotics.
• Daily delivery of antimicrobial susceptibility reports to the pharmacy department.
• Collaboration between pharmacy and laboratory departments on therapeutic interventions.

Main Results:

• An estimated $8,214 in cost savings was achieved through direct interactions between clinical pharmacists and the laboratory.
• Annual cost savings were projected to be $88,554.
• 62% of reviewed therapeutic interventions involved direct laboratory interaction, demonstrating the effectiveness of the collaboration.

Conclusions:

• A strong communication link between hospital pharmacy and laboratory departments is vital for optimizing antibiotic therapy.
• Collaborative efforts can lead to substantial cost savings and more effective antibiotic stewardship programs.
• This integrated approach enhances the efficiency and cost-effectiveness of hospital antimicrobial use.
