Computerized N-acetylcysteine physician order entry by template protocol for acetaminophen toxicity

Area of Science:

• Pharmacology
• Health Informatics
• Clinical Pharmacy

Background:

• Medication dosing protocols can be complex, increasing the risk of errors with traditional physician ordering.
• Computerized physician order entry (CPOE) systems, particularly with order sets, show potential for reducing medication administration errors.
• N-acetylcysteine (NAC) is a critical treatment for acetaminophen poisoning, but its administration requires precise protocols.

Purpose of the Study:

• To evaluate the rate of medication administration errors associated with using CPOE order sets for N-acetylcysteine (NAC) in acetaminophen poisoning.
• To assess the safety and effectiveness of CPOE in managing complex medication protocols in an inpatient setting.

Main Methods:

• A retrospective review of 18 months of computerized inpatient pharmacy records was conducted.
• The study included all patients who received NAC for acetaminophen poisoning.
• Medication administration errors were identified by analyzing records for the form of NAC administered (oral or intravenous).

Main Results:

• A total of 82 cases of acetaminophen poisoning treated with NAC were analyzed.
• No medication administration errors were identified in any of the 82 cases.
• Oral NAC was administered in 31 (38%) cases, and intravenous NAC was administered in 51 (62%) cases.

Conclusions:

• The use of CPOE with order sets for N-acetylcysteine administration in acetaminophen poisoning is associated with zero medication administration errors.
• CPOE serves as an effective tool for the safe execution of complex medication protocols within an inpatient environment.
• Implementing CPOE systems can enhance patient safety by minimizing errors in critical treatment pathways.
