How is payment handled for appointments with Dr. Eikelboom? Is it covered by Ontario Health Insurance Plan (OHIP)?

In ON, medical consultations with specialists like Dr. Eikelboom 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. Eikelboom. 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.

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

While diagnosing and managing diseases like Polypharmacy & Medication Optimization or Investigation of Anemia is crucial, Dr. Eikelboom 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, and participation in meaningful activities.

How long should I expect my appointment to last?

Initial consultations with Dr. Eikelboom are comprehensive and typically require more time, often ranging from 45 to 75 minutes, depending on the complexity of your medical history and concerns. Follow-up appointments are usually shorter. We recommend allowing ample time for your visit, including check-in and potential waiting periods.

Why is reviewing multiple medications (polypharmacy) important?

As people age or develop multiple health conditions, they often take many medications. Polypharmacy increases the risk of side effects, drug interactions, falls, confusion, and non-adherence. A careful review helps ensure each medication is truly necessary, effective, and safe, potentially leading to deprescribing (stopping unnecessary drugs) and simplifying the regimen.

Does Dr. Eikelboom handle prescription refills?

Generally, ongoing prescription refills should be managed through your family doctor (primary care provider). Dr. Eikelboom will make initial recommendations or adjustments, but routine refills are best handled by your family doctor who manages your overall care, unless specific arrangements are made for certain specialized medications.
