Continuous renal replacement therapy (CRRT) is an acute therapy for critically ill patients. There are many life-threatening complications that can occur; therefore, it is imperative that nurses are highly trained in the use and troubleshooting of CRRT. A structured simulation exercise was added to an existing CRRT education program by developing and implementing an annual assessment of knowledge, skills, and attitudes (KSAs) using high-fidelity simulation. The use of high-fidelity simulation as an intervention during annual evaluation of KSAs was shown to be effective in increasing nurse satisfaction, understanding of CRRT principles, and critical thinking skills with the operation of CRRT.
