Classifying errors in preventable and potentially preventable trauma deaths: a 9-year review using the Joint...

Area of Science:

• Trauma Care
• Patient Safety
• Medical Error Analysis

Background:

• Trauma care error classification lacks standardization, hindering benchmarking.
• Existing classification schemes are often locally derived and variable.
• A standardized approach is needed for consistent error analysis in trauma.

Purpose of the Study:

• To classify avoidable errors in a large trauma population.
• To utilize the standardized Joint Commission taxonomy for error classification.
• To identify patterns and common causes of preventable trauma deaths.

Main Methods:

• Reviewed preventable/potentially preventable trauma deaths from an urban, level-1 trauma center (2002-2010).
• Classified 142 avoidable errors using the 5-node Joint Commission taxonomy (impact, type, domain, cause, prevention).
• Analyzed error types, domains, causes, and mitigation strategies.

Main Results:

• 106 (7.7%) of 377 trauma deaths involved 142 avoidable errors.
• Most frequent error type: clinical performance (inaccurate diagnosis).
• Errors predominantly occurred in the emergency department (therapeutic interventions), often due to knowledge deficits. Communication improvement was the primary mitigation strategy.

Conclusions:

• Standardized classification of errors in preventable trauma deaths is feasible.
• Clinical performance errors in early care phases are most common.
• Universal strategies, particularly communication improvement, can mitigate these errors.
