The mean value of the posttest skill was score 92.96, increased by 23.92%, the skill statistically was significant p value=0.000 and the mean value of posttest attitude was 50.06, increased by 6.44%, statistically meaningful p value=0.000, there was an effect of nursing training on improving the knowledge, skills and attitudes of clinical nurses. The results of multivariate analysis of nursing training were statistically significant towards increasing knowledge of clinical nurses (p value=0.000), having the possibility of knowledge increasing 10 times, increasing skills statistically significant (p value=0.000), having the possibility of increasing skills 1.4 times and increasing statistically meaningful attitudes (p value=0.000), having an increased likelihood of attitudes 0.8 times compared to not getting training, no confounding variables were found. Conclusion: Based on this research, the increase in knowledge, skills and attitudes is influenced by nursing training from the aspects of material, methods, facilities, instructors and post-training evaluation methods.
