Class of 2009 Abstract / OBJECTIVES: The purpose of this work is to evaluate the effectiveness of an educational intervention, regarding prescription errors, amongst pharmacy technician students. METHODS: Pharmacy technician students over the age of 18 years attending Apollo College in Tucson, Arizona were eligible to participate. Pretests were given to students to assess baseline knowledge of medication errors. Posttests consisting of questions regarding medication errors were administered to students following a PowerpointTM presentation to assess the effectiveness of the presentation. RESULTS: Pretests and posttests were completed by 18 women and 14 men. Test scores improved significantly from 5.652 to 8.13 out of 10 in the morning class (P< 0.01), 5.8 to 8 in the evening class (P< 0.01), and 5.697 to 8.091 for both classes combined (p< 0.01). Differences in scores based on gender and general employment status did not reach statistical significance (p> 0.05). CONCLUSIONS: An educational intervention is effective in improving pharmacy technician student knowledge about prescription errors.
