A mixed media education-based intervention proved effective in improving knowledge, attitude and compliance with standard precautions, according to an American Journal of Infection Control-published study.
Researchers conducted a randomized, controlled trial with 84 nursing students in a teaching hospital in China. The intervention group, consisting of 42 students, attended three biweekly mixed media education sessions. These sessions included lectures, videos, role-play and feedback as well as 15 to 20 minutes of individual online supervision and feedback sessions after each class. The control group received the same education via self-directed readings.
