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

Deciding between the ER and other care options depends on severity. The Emergency Room is the correct place for acute, potentially severe conditions like difficulty breathing, chest pain, signs of a stroke, major trauma, severe allergic reactions, or uncontrolled bleeding. For ongoing health issues, minor ailments, or routine care, your family doctor offers continuity. Walk-in clinics can handle less severe acute issues. Dr. Hasan and the ER staff are prepared for urgent and life-threatening situations; using the ER appropriately helps ensure timely care for those who need it most. If in doubt about a serious condition, seek emergency assessment.

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

An Emergency Room Doctor, such as Dr. Hasan, 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. Hasan 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?

Wait times in the Emergency Room can fluctuate significantly due to several factors. The primary reason is the triage process: patients with the most severe and time-sensitive conditions are treated immediately. If many critically ill patients arrive simultaneously, or if the department is experiencing high patient volumes or staffing challenges, those with less acute problems may face longer waits. Dr. Hasan and the ER staff understand that waiting can be frustrating and are committed to providing efficient care while ensuring the safety and well-being of all patients.

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. Hasan, 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.

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

If you need to visit the ER, it's very helpful to bring your provincial health card and any other relevant insurance information. A complete list of your current medications (including name, dosage, and how often you take them), any known drug allergies, and a brief summary of your significant medical history (like major illnesses, past surgeries, or chronic conditions) can greatly assist Dr. Hasan and the ER team. If possible, also bring contact information for your family doctor. For children, their immunization record can be useful if it's readily available.

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

Dr. Hasan 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.

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

Yes, it is standard practice for the Emergency Room, including when you are seen by Dr. Hasan, 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.
