In ON, medical consultations with specialists like Dr. Sin are typically covered by your provincial health insurance (Ontario Health Insurance Plan (OHIP)) when you present a valid health card and have the required referral. You generally do not pay directly for the consultation service itself. Some specific procedures, forms, or administrative tasks might not be covered by Ontario Health Insurance Plan (OHIP) and may incur a separate fee according to provincial guidelines. Please inquire if you have questions about uninsured services.

Can I book an appointment directly or do I absolutely need a referral?

A referral from your family physician or another medical specialist is required to see Dr. Sin. As experts in Internal Medicine and Geriatric Care, Internists and Geriatricians see patients based on specific medical questions posed by the referring doctor. This ensures continuity of care and that the consultation is appropriate for your needs. Please have your doctor forward the referral information.

How does Dr. Sin communicate with my family doctor?

Clear communication with your referring physician is a priority. Dr. Sin will send a comprehensive consultation letter outlining the assessment findings, diagnosis (if established), and treatment recommendations. This ensures your family doctor is fully informed and can continue to coordinate your overall care effectively.

Can a family member or friend accompany me to the appointment?

Yes, absolutely. Patients are welcome to bring a family member, friend, or caregiver to their appointment for support, to help recall information, or to ask questions. Especially for complex discussions or if memory is a concern, having a second person present can be very beneficial.

Does Dr. Sin discuss goals of care or advance care planning?

Yes, discussing goals of care is an important part of patient-centered practice, especially in managing chronic illness or in geriatric care. Dr. Sin encourages conversations about patient values, preferences for future medical treatment, and advance care planning (including identifying a substitute decision-maker) to ensure care aligns with what matters most to the patient. She can provide information and facilitate these discussions.

Is the focus mainly on diseases or also on daily function?

While diagnosing and managing diseases like Adrenal Gland Disorders or Management of Select Rheumatologic Conditions is crucial, Dr. Sin also places significant emphasis on maintaining or improving daily function and quality of life, especially for older adults. The goal is often to help patients remain as independent and active as possible, addressing issues like mobility, self-care (Polypharmacy & Medication Optimization), and participation in meaningful activities.
