Chief complaint

The Chief Complaint (CC), or termed Presenting Complaint (PC) in the UK, is a concise statement describing the symptom, problem, condition, diagnosis, physician recommended return, or other factor that is the reason for a medical encounter. The patient's initial comments to a physician, nurse, or other health care professional help form the differential diagnosis.

In some instances, the nature of a patient's chief complaint may determine whether or not services are covered by medical or vision insurance.

Medical students are advised to use open-ended questions in order to obtain the presenting complaint.

Prevalence
The collection of chief complaint data may be useful in addressing public health issues. Certain complaints are more common in certain settings and among certain populations. Fatigue has been reported as one of the ten most common reasons for seeing a physician. In acute care settings, such as emergency rooms, reports of chest pain are among the most common chief complaints. The most common complaint in ERs has been reported to be abdominal pain. Among nursing home residents seeking treatment at ERs, respiratory symptoms, altered mental status, gastrointestinal symptoms, and falls are the most commonly reported.
