Usage

What does inpatient mean? Inpatient is commonly used as an adjective to describe treatment that requires a patient to be admitted to a hospital or other care facility for at least one night. Inpatient is used in contrast with the term outpatient, which describes treatment that does not require a patient to stay overnight. The terms are especially used in phrases like inpatient treatment (which requires the patient to stay overnight at the hospital), inpatient room (where such patients stay), and outpatient procedure (after which the patient can leave, instead of staying for further observation or treatment). Both terms can also be used as nouns referring to such patients. Inpatient is typically used in the context of hospitals, but it can also refer to a patient of a mental health facility or other kinds of clinics. Example: This type of surgery requires inpatient care—typically consisting of a one-week hospital stay.
