Final answer:
The Joint Commission requires accredited healthcare facilities to conduct two disaster drills per year, or one drill and participation in an actual community disaster can replace one required drill.
Step-by-step explanation:
The Joint Commission, which is a body that accredits and certifies healthcare organizations in the United States, has specific requirements for emergency preparedness. Healthcare facilities need to conduct disaster drills to ensure their readiness for unforeseen events. The Commission requires that accredited organizations conduct two disaster drills per year, or one exercise and an actual community disaster incident which a healthcare organization has actively responded to can replace one of the two required drills. This ensures that healthcare providers remain proficient in emergency procedures and improves their level of preparedness for actual disasters.
