Medication stewardship using computerized clinical decision support: A case study on intravenous immunoglobulins

Area of Science:

• Health Informatics
• Pharmacoeconomics
• Clinical Pharmacy

Background:

• Healthcare organizations face pressure to optimize medication safety, reduce waste, and control costs.
• Intravenous immune globulin (IVIG) is a high-cost therapeutic agent requiring careful management.
• Computerized provider order entry (CPOE) systems offer potential for medication use optimization.

Purpose of the Study:

• To describe a CPOE system intervention designed to optimize the use of IVIG.
• To evaluate the impact of a specialty orderset on IVIG prescribing patterns.

Main Methods:

• A specialty orderset for IVIG was developed and implemented within a CPOE system.
• IVIG orders were retrospectively analyzed before and after orderset implementation.
• Prescribed dosing, indications, and duration were compared to evidence-based guidelines.

Main Results:

• Before the orderset, prescribed IVIG doses significantly deviated from expected values (mean difference = -1.8).
• After implementation, prescribed IVIG doses were significantly closer to expected values (mean difference = -1.2, P < .0001).
• The intervention demonstrated improved adherence to optimal IVIG dosing.

Conclusions:

• CPOE order configuration, though complex, can be streamlined to improve medication utilization.
• Understanding institutional ordering patterns is key to optimizing order set design.
• This intervention successfully enhanced the efficient and effective use of IVIG.
