According to the Centers for Medicare and Medicaid Services (CMS), EHRs deliver benefits only when the information and the EHR are standardized and “Structured” in uniform ways, just as ATMs depend on uniformly structured data. Therefore, the “meaningful use” approach requires identification of standards for EHR systems. Certification, which has been coordinated by a national office, ensures that vendors can send and receive standardized data. This assures physicians that they are purchasing a product that will connect properly to other providers in the health system. Certification verifies that the EHR vendor meets national requirements.
