Abstract

Objectives: To evaluate the effectiveness and retention of learning automated external defibrillator (AED) usage taught through a traditional classroom instruction (TCI) method versus a novel self instructed video (SIV) technique in non-critical care nurses (NCCN).

Methods: A prospective single-blind randomized study was conducted over 7 months (April-October 2014) at the Universiti Kebangsaan Malaysia Medical Center, Kuala Lampur, Malaysia. Eighty nurses were randomized into either TCI or SIV instructional techniques. We assessed knowledge, skill and confidence level at baseline, immediate and 6-months post-intervention. Knowledge and confidence were assessed via questionnaire; skill was assessed by a calibrated and blinded independent assessor using an objective structured clinical examination (OSCE) method.

Results: Pre-test mean scores for knowledge in the TCI group was 10.87 ± 2.34, and for the SIV group was 10.37 ± 1.85 (maximum achievable score 20.00); 4.05 ± 2.87 in the TCI and 3.71 ± 2.66 in the SIV (maximum score 11.00) in the OSCE evaluation and 9.54 ± 3.65 in the TCI and 8.56 ± 3.47 in the SIV (maximum score 25.00) in the individual's personal confidence level. Both methods increased the mean scores significantly during immediate post-intervention (0-month). At 6-months, the TCI group scored lower than the SIV group in all aspects 11.13 ± 2.70 versus 12.95 ± 2.26 (p=0.03) in knowledge, 7.27 ± 1.62 versus 7.68 ± 1.73 (p=0.47) in the OSCE, and 16.40 ± 2.72 versus 18.82 ± 3.40 (p=0.03) in confidence level.

Conclusion: In NCCN's, SIV is as good as TCI in providing the knowledge, competency, and confidence in performing AED defibrillation.
