There are a number of standards that impact the electronic health record. The Office of the National Coordinator for Health Information Technology has issued specific standards and certification criteria for EHRs. These standards require that all certified EHR products maintain data confidentiality, ensure interoperability to share information, and can execute a series of well-defined functions. Once an EHR is certified, clinicians and organizations can feel assured that their system is both effective and efficient in supporting information technology.
