The purpose of this study is to investigate the effect of a video-based enteral nutrition education program using QR-Code on the perception, knowledge, and performance of enteral nutrition for intensive care unit(ICU) nurses.
This study is a quasi experimental study with nonequivalent control group pre-post test design. The subjects were nurses working at 6 ICUs within a single university hospital, and 55 nurses in the experimental group and 55 nurses in the control group participated in this study. The video-based enteral nutrition education program using QR-Code was repeated three times to the experimental group. The application of the educational program and data collection were conducted from March 20, 2023 to April 2, 2023.
The collected data were analyzed using the SPSS/WIN 25.0 statistical program. Sample characteristics were analyzed using the descriptive statistics method. The homogeneity of the general characteristics of the control group and the experimental group was analyzed using the χ²-test and Fisher's exact test. Since the dependent variables were not normally distributed according to the Kolmogorov-Smirnov test and the Shapiro-Wilk test, homogeneity of the dependent variables was analyzed by the Mann-Whitney U test. Hypothesis testing on the effect of the video-based critical care enteral nutrition education program using QR-Code was analyzed by Wilcoxon's signed-ranks test.
The results of this study are summarized as follows.
1) Hypothesis 1: 'The experimental group to which the video-based enteral nutrition education program using QR-Code was applied would have a higher perception of enteral nutrition than the control group to which it was not applied.' The control group scored 2.00 points (±5.57) and the experimental group scored 7.89 points (±7.95), showing a statistically significant mean difference in pre and post perception between the two groups (z=-4.04, p<.001). Thus, the first hypothesis was supported.
2) Hypothesis 2: 'The experimental group would have higher knowledge of enteral nutrition than the control group.' There was a statistically significant mean difference in pre and post knowledge the two groups (z=-7.48, p<.001) with .02 points (±1.91) in the control group and 4.18 points (±2.33) in the experimental group. Thus, the second hypothesis was supported.
3) Hypothesis 3: 'The experimental group would have higher performance in enteral nutrition than the control group.' The mean difference was 0.06 points (±3.96) for the control group and 2.00 points (±5.14) for the experimental group. There was statistically significant mean difference in pre and post performance between the two groups (z=-2.20, p=.028). Therefore, the third hypothesis was supported.
In conclusion, the video-based enteral nutrition education program using QR-Code was effective in improving the perception, knowledge, and performance of enteral nutrition among ICU nurses. This enteral nutrition education program using the QR-Code in clinical education can contribute to evidence-based nursing practice through the improvement of perception and knowledge of enteral nutrition.
