The characteristic of high-quality documentation defined as "the physician has fully addressed all concerns in the patient record; the entry has been signed and dated" is Completeness.
Comprehensiveness refers to the extent to which all relevant information is included in the documentation. Legibility refers to the readability of the documentation.
