Effects of BLS training on factors associated with attitude toward CPR in college students.

AIM In order to elucidate the factors for willingness to perform CPR, we evaluated the responses of college students to questionnaires before and after basic life support (BLS) training. METHODS Before and after participating in a small group BLS course, 259 students completed questionnaires. A logistic regression model was used to elucidate independent factors for their willingness to attempt resuscitation. RESULTS Factors associated with willingness to perform BLS for strangers were "anxiety for a bad outcome" (odds ratio (OR) 0.08) and "having knowledge of automated external defibrillator (AED)" (OR 4.5) before training. The proportion of students showing willingness to perform BLS increased from 13% to 77% after the training even when the collapsed person is a stranger. After training, "anxiety for being sued because of a bad outcome" (OR 0.3), and "anxiety for infection" (OR 3.8) were significant factors. Those who preferred to perform BLS without ventilation increased from 40% to 79% (p<0.0001). CONCLUSION The proportion of students showing willingness to perform BLS increased after the training. Significant association between "anxiety for infection" and willingness to perform BLS might indicate that those who wish to perform BLS developed their awareness of risk of infection more than the counterparts. For future guidelines for resuscitation and the instruction consensus, the reluctance of bystanders to perform CPR due to the hesitation about mouth-to-mouth ventilation should be reconsidered with other recent reports indicating the advantage of compression-only CPR.
