Which of the following is a good example of meeting the functionality criterion, as defined by CCHIT?

• A. An EHR uses HL Seven standards
• B. An EHR that requires authorized access
• C. An EHR has a Computerized Provider Order Entry (COPE)
• D. All of the above are good examples of meeting the 'functionality criterion'

Answer: (C)

Functional capability is about what the EHR can do to support clinical work. A key demonstration of this is a Computerized Provider Order Entry (CPOE) system. With CPOE, clinicians can place orders electronically for medications, labs, imaging, and other services directly within the EHR. This directly supports the clinical workflow, improves safety by reducing handwriting and transcription errors, and enables automated decision support and streamlined ordering processes.

HL7 standards are about data exchange between systems—important for interoperability, but they don’t show the EHR performing a core clinical task. Requiring authorized access speaks to security and privacy controls, not to executing a clinical function within the workflow. While these aspects matter, they illustrate different criterion areas rather than the core functionality demonstration. Therefore, the example that best meets the functionality criterion is the presence of a CPOE capability.
