Background:
There is no evidence on the best method for teaching Basic Life Support (BLS).
Aims:
To compare two methods for teaching BLS, assessing the level of cognitive skills.
Methods:
Randomized, prospective study including 68 medical students. BLS algorithms were taught for 60 minutes using either a multimedia presentation (Group I, n=34) or case based discussion (Group II, n=34). Assessments included a scenario-based quiz test and an error-pinpointing video, which the students completed before (T1) and after (T2) teaching. Comparisons between both groups were made on scores of the assessments, actual increases in scores (final value - initial value) and score gains (actual increase/potential increase).
Results:
No significant differences were found between the groups in any of the recorded scores. Both groups improved their T2 scores (p values <0.001). The actual increases in scores and the score gains were similar in both groups. Test scores improved in 55.9% of students in Group I and 58.8% in Group II; video scores improved in 85.3% of Group I and in 82.3% of Group II.
Conclusions:
BLS teaching by either multimedia presentations or case based discussion equally improves the level of cognitive skills among medical students.
