What is the role of the Healthcare Facilities Accreditation Program and Det Norske Veritas Healthcare Inc.?

This question, along with the first one, should be thought of in terms of management or strategic explanations. Yes, COSC is asking for the role; however, think more macro and add why these are important to healthcare delivery. Are they independent of each other, should they be considered important with other initiatives, and how might a healthcare manager utilize these to create a culture of patient safety and quality?
