At Dr. Karen Marie Antoniuk's practice, family medicine is centered on a collaborative partnership to help individuals like you achieve significant improvements in your health, manage ongoing conditions effectively, and enhance your overall well-being. Dr. Antoniuk frequently works with patients towards goals such as:

• Many seek Dr. Antoniuk's help for feeling stressed about caregiving responsibilities for an elderly parent or sick relative. The collaborative goal is successfully and completely completing a course of treatment for an acute infection (like pneumonia or a significant skin infection) or a new condition under Dr. Antoniuk's diligent, meticulous care and important follow-up monitoring, allowing a return to valued activities like spontaneously making and eagerly keeping enjoyable plans with a wide circle of friends for various social outings such as dinners out, casual coffee chats, shared recreational activities, or weekend excursions.
• Dr. Antoniuk frequently helps patients who are dealing with a suspicious mole or skin lesion that has changed in size, shape, or color, or started to itch or bleed. The primary aim is achieving having their complex chronic condition, such as advanced type 2 diabetes, congestive heart failure, difficult-to-control asthma, or multi-joint osteoarthritis, effectively managed and well-stabilized through a collaborative, evidence-based plan developed with Dr. Antoniuk, which often allows them to confidently resume independently and efficiently performing all personal grooming and hygiene tasks (bathing, dressing, toileting) without any difficulty, assistance, or associated pain, maintaining their dignity.
• Dr. Antoniuk understands the impact of a persistent metallic taste in their mouth or other unusual sensory changes. That's why treatment is geared towards benefiting from Dr. Antoniuk's proactive and systematic approach to mental health screening and discussion during routine visits, leading to earlier identification and support for emerging psychological distress, helping patients get back to feeling mentally sharp, agile, and capable enough to readily engage in complex problem-solving tasks, intricate strategic thinking exercises, or detailed analytical work required in their profession or personal projects with greater ease.
• Patients with a recurring ear infection, or their child tugging at their ear and being fussy can find relief and achieve achieving substantially better and more integrated management of their multiple co-existing chronic conditions (multimorbidity) through the highly coordinated, holistic, and patient-centered approach to care championed by Dr. Antoniuk under Dr. Antoniuk's care, often allowing them to resume feeling consistently rested, fully alert, and cognitively sharp enough to drive safely and defensively for both short daily commutes and much longer, more demanding road trips or family vacations without former limitations.

What exactly is a family doctor (Family Doctor) and what is their role?

A family doctor (Ontario) is a physician who has completed post-graduate training in family medicine. She is skilled in providing continuous and comprehensive medical care, health maintenance, and preventive services to patients of all ages. This includes diagnosing and treating a vast array of illnesses, managing complex long-term health conditions, offering health education and counseling on lifestyle choices, and acting as your advocate and guide within the broader healthcare system.

Does Dr. Antoniuk at her clinic offer virtual (video) or phone appointments?

Yes, Dr. Antoniuk offers virtual (video) and/or phone appointments for certain types of consultations when clinically appropriate. These can be convenient for discussing some test results, managing stable chronic conditions, prescription renewals for ongoing medications (not controlled substances), or for certain mental health follow-ups. However, many conditions, new problems, or situations requiring a physical examination will still necessitate an in-person visit for accurate assessment and diagnosis. Please discuss with our reception staff or Dr. Antoniuk if a virtual appointment might be suitable for your specific needs. Provincial health plan coverage for virtual visits may vary; please check with our clinic regarding any potential fees for uninsured virtual services.

What happens if Dr. Antoniuk determines I need to see a medical specialist?

As your family doctor, Dr. Antoniuk acts as your primary care coordinator. If she believes your condition requires specialized assessment or treatment, she will explain why a specialist consultation is necessary and will arrange the referral. Dr. Antoniuk will send your pertinent medical details to the specialist. The specialist's office will then typically contact you to book the appointment. It's important to keep our clinic informed of any specialist appointments you attend and any new diagnoses or treatments recommended by the specialist so Dr. Antoniuk can continue to coordinate your overall care effectively.

How can I find a family doctor (Family Doctor) in ON who is accepting new patients?

The College of Physicians and Surgeons of Ontario often has a 'Find a Doctor' tool or list. In Ontario, you can register with Health Care Connect. You can also ask friends, family, or colleagues for recommendations. Contacting local community health centres or new patient clinics directly may also be helpful. Finding a family doctor who is accepting new patients can be challenging and may take time.

What is 'continuity of care' and why is it important with a family doctor like Dr. Antoniuk?

Continuity of care refers to the process where your family doctor, Dr. Antoniuk, sees you for your health needs on an ongoing basis, rather than seeing different doctors for different issues. This consistency is valuable because Dr. Antoniuk becomes familiar with your medical background, your lifestyle, and what's 'normal' for you. This knowledge aids in quicker diagnosis, more effective treatment plans, better chronic disease management, and ensures that your care is well-coordinated across the healthcare system. It's about having a trusted healthcare partner throughout your life.

Do I need a referral to see a family doctor (Family Doctor) in ON?

Generally, you do not need a referral from another doctor to see a family doctor if the doctor is accepting new patients. However, finding a family doctor who is accepting new patients can be challenging. Resources like Health Care Connect in Ontario, a local health authority website, or the provincial College of Physicians and Surgeons patient-doctor matching service (if available) may be helpful. A referral is usually required from a family doctor to see most medical specialists.

What should I do if I have an urgent medical issue when the clinic is closed?

If you have a life-threatening medical emergency, please call 911 or go to the nearest hospital emergency department immediately. For urgent, non-life-threatening issues that cannot wait until our clinic reopens, you may consider visiting an urgent care centre or a walk-in clinic.
