What is the primary role of an Emergency Room Doctor like Dr. Waines?

An Emergency Room Doctor, such as Dr. Waines, is a physician specifically trained to provide immediate medical evaluation and treatment for a wide spectrum of acute illnesses and injuries, ranging from minor concerns to critical, life-threatening 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 Room Doctor trained to provide immediate medical care for a wide range of acute illnesses and injuries., Dr. Waines 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.

When should I go to the Emergency Room (ER) where Dr. Waines 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. Waines and the ER team are there for true emergencies.

Will my family doctor be informed about my visit to the ER with Dr. Waines?

Maintaining communication with your family doctor is crucial for your ongoing health management. After your assessment and treatment by Dr. Waines in the Emergency Room, a report of your visit is generally forwarded to your primary care physician, especially if follow-up care or medication adjustments are necessary. To facilitate this, please make sure the ER registration staff have the correct contact details for your family doctor.

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. Waines 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.

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

The Emergency Room, where Dr. Waines 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.

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. Waines, 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.
