Objectives: The purpose of this article was to examine the effect of the "SAFE" education protocol on improving safe medication administration for home healthcare clients. Methods: We used a quasi-experimental design and subjects were a convenience sample of thirty-four home healthcare clients recruited from a homecare center in a hospital in southern Taiwan. The group received the "SAFE" education protocol, including Standardizing health education about safe medication administration, Assessing medication adequacy, Facilitating a safe medication environment, and Evaluating medication safety (acronym: SAFE). The program was held once a month, for 3 months. The outcomes were measured before intervention and 1 month post-intervention. Results: The results showed an average of 7 medication problems in home healthcare clients before intervention and one, 1 month post-intervention (X^2 =4.17, p<0.05). The scores for perception of medication safety by caregivers increased from 6.7 before intervention to 8.4 at 1 month post-intervention (t= -5.5, p<0.01). Conclusions: The "SAFE" education protocol may effectively decrease the medication problems experienced by home healthcare clients and increase the perception of medication safety by caregivers.
