The Acute Ambulatory Care Unit (AACU) is a short stay medical unit that provides urgent assessment, investigation, and management for patients with new medical problems and those with chronic medical illnesses. This work up and management occurs within a 24-hour timeframe.
The unit is staffed by a physician who specializes in General Internal Medicine, as well as medical nurses. The unit also has access to a wide range of medical diagnostics and testing, and can arrange for urgent referrals to other medical specialties.
The goal of the AACU is to manage patients with chronic medical conditions so they can avoid lengthy visits to the emergency room and inpatient hospitalizations.
Patients must be referred by another medical doctor, and there is direct contact between the referring physician and the general internist to assess appropriateness before the patient is accepted.
The entrance to the AACU is located at the Grosvenor Street entrance of Women’s College Hospital (between Bay St. and Queen’s Park Circle). There is a designated drop off area at the entrance to the AACU.
