The best test to provide assurance that a health care organization is handling patient data appropriately is compliance with local laws and regulations, as these are the primary sources of authority and obligation for data protection and privacy. Compliance with action plans, industry standards, or organizational policies and procedures are also important, but they may not cover all the legal requirements or reflect the currentbest practices for handling patient data.
