Background
Cardiac arrest in hospital accounts for 80% of hospital deaths, and the survival rate is not significantly different from that of pre-hospitalized cardiac arrest patients. The nurses are the most likely to be the first to see a patient in a hospital cardiac arrest. Advanced Life Support (ALS) training is being conducted for nursing students who will become future nurses, and the sustainable effect of the training is as short as 3 to 6 months.
Purpose
The purpose of this study was to measure the knowledge, self-efficacy, and skill performance of the ALS 6 months after the training by transferring the videos taken during the final skill evaluation to the nursing students after the ALS training.
Design and Methods
This study is an experimental study of a randomized control group design to verify the effects and retention after ALS training. Knowledge, self-efficacy, and skill performance of ALS were evaluated for all subjects immediately after the training and subjects were videotaped while receiving final skill evaluation. The study subjects were randomly assigned by a non-participant assistant to the experimental group and control group using the blocked randomization method. After that, we sent the video to the experimental group through the mobile phone messenger application once a month from the third month after training, and we did not perform any arbitration for the control group. Approximately six months after the training day, the same two evaluators who participated in the preliminary survey conducted a follow-up examination of the measured variables by applying the blinded method.
Results
Three of the 25 subjects in the experimental group refused to follow-up on the individual schedule, and 4 subjects in the control group disappeared due to the lack of communication, and 22 subjects and 21 subjects in the experimental group and 21 subjects in the control group were included in the analysis of this study. Six months after the resuscitation training, knowledge scores decreased significantly in both experimental and control groups (p < 0.001). The self - efficacy of the test group decreased by about 3 from 50.55 to 47.18 in the experimental group (p = 0.089), while it decreased by 10 in the control group from 50.67 to 39 (p < 0.001). In the experimental group, the performance of the technique was decreased from 27.5 to 26.68 by about 1, while the control group was significantly decreased by 11 from 27.95 to 16.9 (p < 0.001).
Conclusion
Self-study with videos taken at the time of ALS skill performance evaluation can help to increase the sustainable effect of education such as knowledge, self-efficacy, and skill performance. Further studies will require long-term follow-up such as 1 year or more after the training.
