The qualitative consisted of group discussion to find key issues and guidelines for the development of medication administration. Models. Quantitative data were analyzed using percentage, mean, standard deviation and Wilcoxon Matched pairs signed Rank test. The qualitative data synthesized the medication administration model by content analysis. 

The results showed that medication administration model for safety in IPD according to the 10R and 3 process: Pre-administration, during administration, and after administration.

The observational results of the medication administration practices of nurses pass the criteria of 80%. Self-evaluation of nurses' practice after using the improved medication administration model. It was found that nurses' practice for patient safety after using the model was higher than before statistical significance at the 0.05 level.
