Chapter 2: The Organization of Hospitals

Outpatient Hospital Departments

Hospitals often have a variety of specialized outpatient clinics which complement the type of inpatient services they offer. Patients who do not need to spend a night in a hospital are considered outpatients; their hospital stay is less than 24 hours. For example, if a hospital is designated as the cardiology centre for the region, it will likely have a variety of outpatient cardiac clinics, as well as inpatient cardiac units such as CCU, cardiology, or CVICU. In addition, most general hospitals will offer a variety of routine diagnostic and therapeutic services that serve the needs of both outpatients and inpatients, such as laboratory or diagnostic imaging services.

Similar to inpatient units, outpatient departments typically require clerical support. Given their outpatient nature, these departments are typically staffed during the day from Mondays to Fridays. However, some diagnostic services which provide 24/7 support for inpatient units and the emergency department may have expanded clerical coverage.

Below is a list of some outpatient departments commonly found in mid-size hospitals. Larger hospitals, or hospitals providing specialized services, will have many more focused outpatient clinics and services that are noted here.

A medical radiation technologist (MRT) prepares a patient for an MRI scan; diagnostic or medical imaging is one of the many outpatient departments in hospitals.

Geriatric Medicine Clinic: Provides comprehensive assessment and community support referrals for patients who have complex conditions associated with aging, including memory loss, mobility problems and falls (University Health Network, 2024c).

Infusion Clinic: Provides outpatient intravenous therapy for patients requiring IV medications such as biologics, antibiotics, or blood products.

Laboratory Services: Provides a wide range of tests on specimens, including blood, body fluids, and tissues, to diagnose, monitor and treat disease.
