The purpose of the evaluation influences the focus of the examination and the form of documentation. The reason for the evaluation usually includes (but may not be limited to) the chief complaint of the patient. It should be elicited in sufficient detail, including the patient's words, to permit an understanding of the duration of the complaint and the patient's specific goals for the evaluation. If the symptoms are of long standing, the reason for seeking treatment at this specific time is relevant; if the evaluation was occasioned by a hospitalization, the reason for the hospitalization is also relevant. If the patient did not initiate the evaluation, the reason another individual or entity may have requested or required it should be noted. The opinions of other parties, including family, can also assist in establishing a reason for evaluation. Under some circumstances (e.g., with psychotic or uncommunicative patients), input from others may be crucial.
