National CRNA Week is the AANA’s annual celebration of anesthesia patient safety and the nation’s 52,000+ Certified Registered Nurse Anesthetists and student registered nurse anesthetists who safely and cost-effectively provide approximately 43 million anesthetics each year. Known as National Nurse Anesthetists Week as recently as 2014, the new name for this popular event helps patients, hospital administrators, healthcare professionals, policymakers, and others become more familiar with the CRNA credential and the exceptional advanced practice registered nurses who have earned it.
