A Thesis submitted to The University of Arizona College of Medicine - Phoenix in partial fulfillment of the requirements for the Degree of Doctor of Medicine. / The Rural Trauma Team Development Course (RTTDC) is a one day course given to trauma personnel at various rural medical centers across the United States with the goal of improving care to injured patients in such areas. The purpose of this study is to determine the retention of RTTDC knowledge by those trained, as well as the migration rates of trainees out of these sites. The teaching of the RTTDC includes both pre‐test and post‐test assessments to ensure proper skills were learned. There was a statistically significant increase in score from the average course pre‐test score of 76.9% to the average course post‐test score of 92.1%. At this interim analysis, plotting the study post‐test scores over time since the course was given does reveal a pattern of decreased scores over time. The average study post‐test score of 88.8% is only slightly below the average initial post‐test score of 92.1%, though this was not significant. When assessed by individual questions, the participants scored significantly worse with questions addressing initial approach to the trauma patient and management of burn patients. There was no significant difference in scores between trauma team role. In this data set, the percentage of trainees remaining at course sites was 100%, though this was not expected based on previous studies. Our goal of 200 participants to achieve power has not been met at this time, but this could be established if more sites become involved, thus providing significant feedback for possible course revision.
