- When should I go to the Emergency Room (ER) where Dr. Freeman 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. Freeman 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 should I bring with me if I need to go to the Emergency Room where Dr. Freeman 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. Freeman 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.
- Will my family doctor be informed about my visit to the ER with Dr. Freeman?
- Yes, it is standard practice for the Emergency Room, including when you are seen by Dr. Freeman, 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.
- 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. Freeman 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.
- What is the primary role of an Emergency Room Doctor like Dr. Freeman?
- The main responsibility of an Emergency Room Doctor like Dr. Freeman, a trained emergency physician, is to care for patients with acute medical problems that require immediate attention. He is an expert at quickly assessing patients, ordering and interpreting diagnostic tests, initiating life-saving treatments, and performing a variety of emergency procedures.
