Naval Aviation Safety in Medicine: Reducing Errors from Human Factors
Abstract
Background: Medical errors are a major cause of morbidity and mortality in the healthcare industry. Human factors make errors much more likely to occur. However, explicit instruction on mitigating human factors is underrepresented in graduate medical education. The Naval Aviation community has systematically evaluated the risk posed by human factors and implemented specific approaches for reducing error, an intervention which has exponentially decreased preventable aviation mishaps over decades. Applying those principles from Naval Aviation to the way in which healthcare is delivered will reduce errors and improve safety.
Description of the Project: Human factors are a broad category within error analysis. Naval Aviation has grouped human factors into four broad categories: active factors, preconditions, supervisory factors, and organizational factors. Naval Aviation applies frameworks such as Threat and Error Management (TEM) and Crew Resource Management (CRM) to reduce the risks posed by these factors and prevent human error from contributing to mishaps. TEM and CRM directly apply to the medical industry and could immediately reduce dangerous mistakes that adversely affect patient outcomes.
TEM is a system designed to correct deviations from a standard. Deviations consist of threats, errors, and undesired states. Threats are risks which are known ahead of time (such as the risk of infection). We control threats by preparing for them appropriately (by giving perioperative antibiotics). Errors are harmless, but unintended, deviations that cannot be prevented (such as marking a wrong site for surgery). We control errors by identifying and repairing them (confirming the surgical site with the patient and perioperative team prior to induction of anesthesia). Undesired states are situations in which serious harm is imminent (such as excessive uncontrolled bleeding). We control undesired states by recovering from them (massive transfusion, IR embolization, etc). Effective TEM application requires the seven critical skills of CRM: Situational Awareness, Assertiveness, Decision Making, Communication, Leadership, Adaptability, and Mission Analysis.
We presented these principles to second year UCSD anesthesia residents as part of the professional development didactic series. We utilized analogies from real aviation disasters, description of aviation’s culture of safety, and group discussion on healthcare examples to illustrate how to apply TEM and CRM.
Lessons Learned/Expected Outcomes: 80% of respondents reported no prior knowledge of how the principles of CRM existed within their clinical duties. After presenting on TEM and CRM, 100% of respondents agreed that the information would positively influence their professional practice. Continued TEM and CRM training will improve team members’ ability to ensure patient safety in any situation or environment.
Recommendations/Next Steps: Educational emphasis on TEM/CRM, human factors, non-hierarchical communication, identification of cognitive bias, single provider CRM, and other Naval Aviation topics will empower members of the healthcare team and reduce preventable errors in patient care.
