Emergency Department

The Emergency Departments at Markham Stouffville Hospital provide rapid treatment for community members who experience sudden illness or trauma.  Operating without interruption, our Emergency Departments are staffed by a team of experts specializing in emergency medicine. Each of our Emergency Departments have access to state-of-the-art diagnostic assessment equipment and laboratory services.

Care We Provide 

This service, which may be your first point of contact with Markham Stouffville Hospital, exists to provide initial treatment of serious illnesses and injuries, some of which may be life threatening and requiring immediate attention. After initial assessment and treatment, patients are admitted to the hospital, transferred to a specialty hospital or discharged.

In order to ensure timely, quality care for the most acute cases arriving at our hospital, we triage our incoming patients to determine the nature and severity of their condition. 

Additionally at the Markham Site we direct patients with minor or less urgent symptoms to our Green Zone.

Frequently Asked Questions

What should I bring with me?
It is especially helpful if patients arriving at the Emergency Department to list or bring samples of all medication they are taking. In addition, you should make us aware of any known allergies. Many pharmacies will now prepare individualized information charts for you. 
 
Where should I go if I have post-surgical problems?
If patients are visiting emergency for post-surgical problems, it is best to return to the hospital that conducted the surgery.  They will have quick access to your important medical information.
 
What is the Green Zone?
Markham Stouffville Hospital operates a separate fast track service to address minor and rapidly treatable conditions. 

Our Green Zone makes sure that minor health care needs receive more timely attention in a separate clinic, freeing the Emergency Department to address the critical care needs of more urgent cases.  You may receive the appropriate care or treatment from any member of our team including a doctor or other specialist as may be consulted.

If the triage nurse assesses your symptoms or injuries to be less severe than those of other patients, you will be referred to our Green Zone, in order to minimize your wait time.  

What is the Yellow Zone?
After you are assessed by the triage nurse, you may receive care in the Yellow Zone, a treatment area for ambulatory patients with minor to moderate situations. In this area stretchers are only used for assessments and certain treatments; you may be asked to return to the Yellow Zone waiting room to wait for further assessments, tests and results.

When will I be seen?
All patients are seen by a triage nurse and assigned a triage level based on the Canadian Triage Acuity Scale. 

There are five triage levels ranging from #1 being the most critical to #5 being non-urgent.  Patients are seen in the order of their triage level and not based on time of arrival.  If your your condition changes while you are waiting to see a doctor let the nurse know immediately.

This Triage approach allows us to give priority to those patients whose ailments are most severe and acute.
