Medication Safety in Anesthesiology: A Closed-Claims Analysis.

Area of Science:

• Anesthesiology
• Patient Safety
• Medical Malpractice

Background:

• Medication errors persist despite established safety guidelines in anesthesia care.
• Closed claims analysis offers insights into factors contributing to medication errors and patient harm.

Purpose of the Study:

• To analyze medication-related closed claims in anesthesia from 2012-2022.
• To identify injury severity, common complications, and clinical themes associated with anesthesia medication errors.

Main Methods:

• A descriptive analysis of 140 medication-related closed claims from a national malpractice insurer database.
• Examination of injury severity, types of injuries, anesthetic techniques, and medications involved.

Main Results:

• Most claims (59%) involved severe injuries, including death or permanent disability.
• Oversedation leading to respiratory or cardiac arrest was the most common clinical theme (29%).
• The average claim cost was $704,000.

Conclusions:

• There is an ongoing need to enhance perioperative medication safety in both hospital and ambulatory settings.
• Oversedation presents a high-risk area in anesthesia care, alongside risks associated with neuromuscular blocking drugs and local anesthetics.
