Another term for outpatient care is:

Outpatient care refers to medical services provided to patients who do not require hospital admission and do not stay overnight. This type of care allows patients to receive treatment, diagnosis, or rehabilitation while still being able to return home the same day. The term "ambulatory care" specifically describes this concept, emphasizing that patients are typically mobile and can walk in and out without needing significant medical supervision or an overnight stay. This reflects the convenience and accessibility of outpatient services, which include routine check-ups, minor surgical procedures, and various diagnostic tests.

The other options describe different types of care settings. Inpatient care refers to patients who are admitted to a hospital for more intensive treatment. Emergency care typically addresses acute medical situations that require immediate attention. Secondary care usually involves specialized medical services that are referred by primary care providers. These variations in the definitions illustrate the distinct nature of outpatient services compared to other healthcare service types.
