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

ABSTRACT

BACKGROUND: We 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. METHODS: A 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. RESULTS: Forty-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. CONCLUSIONS: Interprofessional 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.
