JCAHO accredits/certifies hospitals, inspects them. They have guidelines for quality and other factors of hospital care. They do offer accreditation for Skilled Nursing Facilities. JCAHO is pretty strict and intense, the inspections really get administrators, doctors, and nurses on their toes. You'll know when JCAHO is coming by the excitement in the air. It's usually an annual event.
