What should I bring with me if I need to go to the Emergency Room where Dr. Reardon works?

When coming to the Emergency Room, please ensure you have your health insurance card (e.g., OHIP, AHCIP, MSP, RAMQ card). It's also extremely beneficial for Dr. Reardon and the medical team if you can provide an accurate list of all medications you are currently taking (including over-the-counter drugs and supplements), a list of any allergies you have, and details of any important past medical conditions or surgeries. If you are accompanying someone else, try to have this information for them.

Why are wait times in the Emergency Room sometimes long?

Emergency departments, including the one where Dr. Reardon practices, utilize a triage system. This means patients are not seen on a first-come, first-served basis, but rather based on the severity and urgency of their medical condition. Patients with life-threatening injuries or illnesses (like heart attacks, strokes, or major trauma) are always prioritized and seen first. This can result in longer wait times for those with less urgent conditions, especially during peak hours or when the ER is managing multiple critically ill patients. The entire ER team, including Dr. Reardon, works diligently to provide care to everyone as quickly and safely as possible.

When should I see Dr. Reardon in the ER versus my family doctor for a health issue?

Dr. Reardon and the Emergency Room team are best equipped to handle acute, severe, or potentially life-threatening medical conditions. For ongoing care, management of chronic illnesses (unless there's an acute exacerbation), routine check-ups, preventative health measures, prescription refills for stable conditions, and non-urgent health concerns, your family doctor is the most appropriate healthcare provider. They offer continuity of care and have a comprehensive understanding of your overall health history. If your condition is not an emergency, consulting your family doctor or a walk-in clinic is generally recommended.

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. Reardon, ensuring that patients with life-threatening conditions receive immediate care. They are a key part of the ER team that ensures patient safety and efficient flow.

When should I go to the Emergency Room (ER) where Dr. Reardon works, versus seeing my family doctor or going to a walk-in clinic?

The Emergency Room is for serious or life-threatening medical conditions that require immediate attention. 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. Reardon and the ER team are there for true emergencies.
