Self-efficacy of Intervention in Improve Nurses Beliefs about Drug Errors

Background : Medication errors are preventable events that may lead to inappropriate medication use or patient harm during prescribing, transcribing, dispensing, administration, or monitoring practices. Objective: The aim of the study to assess the impact of a Health Belief Model-based intervention on improving nurses' self-efficacy and beliefs concerning medication dosage errors in pediatric wards. Methods: A randomized controlled trial with a true experimental design was used for the program from October 1, 2024, to May 1, 2025. Five public healthcare facilities with pediatric wards were included in the study. More than 250 questioners were distributed to nurses from pediatric wards in Mosul hospitals at random. The nurses were then selected for the study by either giving the questioners to one and leaving one on or two, or the other way around, giving the questioners to pediatric ward nurses and leaving one. The researcher then received 165 questioners, and approximately 90 nurses did not fit the criteria. Lastly, there is a chance that there will be 26 male and 34 female pediatric ward nurses in the two groups, each holding a different position.30 nurses who consented to participate in the study were included in the sample, and 30 nurses who work in pediatric wards were included in the control group. The experimental and control groups were created by random assignment. Version 26 of the Social Science Statistical Package (SPSS) was used in the investigation to analyze the data. The statistical techniques used to analyze data and assess results. Results: The finding show that the changes in nurses' knowledge regarding medication dosage errors across the study phases. The mean score during the Pre phase was 7.888 (Fair level), reflecting a need for improvement. After the intervention, the Post1 phase showed a significant increase to 17.444 (Good level), demonstrating its effectiveness. By the Post2 phase, the mean score slightly decreased to 17.333 but remained at a good level, indicating sustained knowledge retention. Conclusion: This study concluded that the program was effective through the three tests that were conducted on nurses in hospitals, as they were tested first and their knowledge of the directions of incorrect drug doses was weak and unacceptable, while when the intervention, i.e. the training program, was conducted, their knowledge became good in the second test and the researchers continued to follow them after the program for two months. They were tested for the third time and it was found that they still retained the same information, i.e. their knowledge remained in a positive and high direction at the same time.
