FAQ
Frequently Asked Questions
It is standardly written as one word: 'outpatient'. The hyphenated form 'out-patient' is now rare.
No, 'outpatient' is not used as a verb. You might say 'treat as an outpatient' or 'discharge to outpatient care'.
The direct opposite is an 'inpatient', a patient who is admitted to a hospital for at least one night.
Not necessarily. Many serious treatments and surgeries are now performed on an outpatient basis due to medical advances. It indicates the care setting, not the severity.
