The effect of educational intervention on the level of knowledge and comfort of nurses in heart failure self-care training: A quasi-experimental study

Abstract

The present study aims to determine the effect of educational intervention on the level of knowledge and comfort of nurses in heart failure (HF) self-care training. This quasi-experimental study, lacking a control group, was conducted in 2021 with 102 nurses working in the coronary care unit at Rajaei Cardiovascular Medical and Research Institute, Tehran, Iran. The nurses were divided into four groups of 20 and one group of 22, participating in a 2.5-hour online training session. A pre-test was administered two weeks before the training, and a post-test was conducted four weeks after the training, using completed questionnaires. Data analysis was performed using SPSS version 24 software, employing paired t-tests, independent t-tests, and one-way analysis of variance. Before the training, the average knowledge score was 12.05 (standard deviation [SD]=2.23), and the average comfort score was 22.84 (SD=5.09). Following the training, the average knowledge score increased to 17.90 (SD=1.05), and the average comfort score rose to 31.05 (SD=2.14). The mean nurses' knowledge and comfort scores showed a significant increase after the educational intervention (P<0.001). The findings indicated that the educational intervention effectively enhanced nurses' knowledge of HF self-care training and increased their comfort levels in teaching patients.
