Patient

A patient is any recipient of health care services. The patient is most often ill or injured and in need of treatment by a physiotherapist, physician, physician assistant, advanced practice registered nurse, psychologist, podiatrist, veterinarian, or other health care provider.

Etymology

The word patient originally meant 'one who suffers'. This English noun comes from the Latin word patiens, the present participle of the deponent verb, patior, meaning 'I am suffering,' and akin to the Greek verb πάσχειν (= paskhein, to suffer) and its cognate noun πάθος (= pathos).

Outpatients and inpatients

An outpatient (or out-patient) is a patient who is hospitalized for less than 24 hours. Treatment provided in this fashion is called ambulatory care. Sometimes surgery is performed without the need for a formal hospital admission or an overnight stay. This is called outpatient surgery. Outpatient surgery has many benefits, including reducing the amount of medication prescribed and using the physician's or surgeon's time more efficiently. More procedures are now being performed in a surgeon's office, termed office-based surgery, rather than in a hospital-based operating room. Outpatient surgery is suited best for healthy patients undergoing minor or intermediate procedures (limited urologic, ophthalmologic, or ear, nose, and throat procedures and procedures involving the extremities).
