The medical chart on a particular patient provides data specific a patient's key clinical data and medical history, such as demographics, vital signs, diagnoses, medications, treatment plans, progress notes, problems, immunization dates, allergies, radiology images, and laboratory and test results.
To me; citation of such a chart in APA could be considered a technical report; where the client/patient IS the subject of research or subject of the problem being studied by the author (Doctor). As in a technical report; suggestions for treatment, facts and conclusions related to the situation are all present in such a record.
