Group S all passed the post-ATLS multiple-choice test (with correct answer percentages of 60.3% +/- 6.6% pre-ATLS versus 88.8% +/- 5.6% post-ATLS). Affect was assessed post-ATLS for motivational factors, interactivity, and attitude toward trauma care. Multiple-choice and psychomotor testing using ATLS scoring criteria were used.
Groups P and I were subdivided based on the length of time since the course had been completed: P1, less than 2 years (n = 22) P2, more than 2 years (n = 11) I1, less than 2 years (n = 16) and I2, more than 2 years (n = 10). Group S read the manual before pretesting. Three groups (S, 16 students P, 33 providers and I, 26 instructors ) were evaluated.
We assessed the attrition of ATLS skills among ATLS providers and instructors in this country. Mexico has had the Advanced Trauma Life Support (ATLS) program since 1986.
