- What should I bring with me if I need to go to the Emergency Room where Dr. Allen works?
- To help Dr. Allen and the ER staff provide the best care, please bring your government-issued health card. A list of all medications you take, including prescriptions, over-the-counter drugs, vitamins, and herbal supplements, is also vital. Knowing your allergies and any chronic health conditions or previous major surgeries will also help the team. If you regularly see other specialists, their contact information might also be useful.
- What is the role of the triage nurse when I arrive at the ER?
- The triage nurse in the ER performs a crucial initial assessment to rapidly evaluate how serious your condition is. They will ask about your symptoms, check your vital signs (like blood pressure, heart rate, and temperature), and assign you a triage level. This level dictates how quickly you need to be seen by an Emergency Room Doctor such as Dr. Allen, ensuring that patients with life-threatening conditions receive immediate care.

- When should I see Dr. Allen in the ER versus my family doctor for a health issue?
- The Emergency Room, where Dr. Allen practices, is designed for urgent and emergency situations—conditions that require immediate medical intervention to prevent serious harm or death. Your family doctor, on the other hand, provides comprehensive primary care, including treatment for common illnesses, management of long-term health conditions, immunizations, and preventative screening. For problems that are not immediate emergencies, your family doctor can provide more personalized and continuous care. If you have a non-urgent issue, the ER may involve a long wait.
- When should I go to the Emergency Room (ER) where Dr. Allen works, versus seeing my family doctor or going to a walk-in clinic?

Examples include: severe chest pain or pressure, difficulty breathing or shortness of breath, signs of a stroke (like sudden weakness or numbness, trouble speaking), major injuries or uncontrolled bleeding, severe allergic reactions, high fever with confusion, or loss of consciousness. For non-urgent issues, minor illnesses, medication refills, or routine check-ups, your family doctor or a walk-in clinic is usually more appropriate. If you're unsure about the severity of your condition, it's often best to err on the side of caution and seek emergency care or call your provincial telehealth line for advice. Dr. Allen and the ER team are there for true emergencies.

Their core role involves rapid assessment (triage and diagnosis), stabilization of vital functions, performing necessary emergency procedures, and making crucial decisions about patient disposition (admission, transfer, or discharge). As a an Emergency Physician with certification from the College of Family Physicians of Canada in Emergency Medicine, skilled in managing urgent medical conditions, Dr. Allen is highly skilled in managing the unpredictable and often high-pressure environment of the emergency department, working collaboratively with a team of nurses, technicians, and other specialists.
- Why are wait times in the Emergency Room sometimes long?
- The length of your wait in the ER is determined by a medical sorting process called triage, which Dr. Allen and the team follow. This system ensures that the sickest patients receive care first. Factors like the number of patients currently in the ER, the severity of their conditions, and the availability of treatment rooms and staff can all impact wait times. While it can be difficult to wait, please know that the emergency team is working hard to attend to every patient based on medical priority.
- Will my family doctor be informed about my visit to the ER with Dr. Allen?
- Yes, it is standard practice for the Emergency Room, including when you are seen by Dr. Allen, to send a detailed summary of your ER visit to your designated family doctor, provided you share their contact information during registration. This report typically includes the reason for your visit, significant findings, any treatments administered, and recommendations for follow-up. This ensures continuity of care and keeps your family doctor informed about important changes in your health status. Following up with your family doctor after an ER visit is usually recommended.
