Who is referred to as the highest-ranking doctor in a hospital setting?

The highest-ranking doctor in a hospital setting is the attending physician. This role typically involves overseeing the care of patients and is often the doctor responsible for making critical decisions regarding a patient's treatment. The attending physician collaborates with various departments and is usually the most senior physician involved in a patient's management.

In contrast, while the chief of surgery holds a significant position, overseeing surgical procedures and surgical staff, this role usually pertains specifically to surgical departments rather than encompassing the overall medical care provided within the hospital. The emergency room doctor, although crucial, works within the confines of emergency care and may not have authority over inpatient care decisions. The head nurse plays a vital role in patient care but does not have the same clinical decision-making responsibilities as the attending physician. Therefore, the attending physician is recognized as the highest-ranking doctor, responsible for the comprehensive care and oversight of patients in the hospital setting.
