Evaluating the long-term impact of the Trauma Team Training course in Guyana: an explanatory mixed-methods approach

Abstract

BackgroundWe evaluated the retention of trauma knowledge and skills after an interprofessional Trauma Team Training (TTT) course in Guyana and explored the course impact on participants. MethodsA mixed-methods design evaluated knowledge using a multiple-choice quiz test, skills and trauma moulage simulation with checklists, and course impact with qualitative interviews. Participants were evaluated at 3 time points; before, after, and 4 months after TTT. ResultsForty-seven course participants included 20 physicians, 17 nurses, and 10 paramedical providers. All participants had improved multiple-choice quiz test scores after the course and retained knowledge after 4 months, with nonphysicians showing the most improved scores. Trauma skill and moulage scores declined slightly after 4 months, with the greatest decline observed in complex skills. Qualitatively, course participants self-reported impact of the TTT course included improved empowerment, knowledge, teamwork, and patient care. ConclusionsInterprofessional team-based training led to the retention of trauma knowledge and skills as well as the empowerment of nonphysicians. The decline in performance of some trauma skills indicates the need for a regular trauma update course.
