Expertise Should Be Visible And Verifiable
Health information is more useful when you can see who contributed to it, whether they wrote or reviewed it, which subjects fall within their professional scope, and when the page was last reviewed. An expert profile supports transparency; it does not replace an individual assessment or create a clinician-patient relationship.
What Our Experts Contribute
Clinical Context
Experts help ensure explanations reflect appropriate respiratory and sleep-health concepts, limitations and safety boundaries.
Practical Education
Professional experience can make testing, CPAP, mask comfort and follow-up information clearer and more useful.
Defined Review
A reviewer checks a specific version within an appropriate scope. Material changes may require another review.
Written by, Reviewed by and Editorial Review
How We Check Credentials and Review Claims
- Verify Identity and Qualifications. Credentials, registrations, education and affiliations are checked against approved professional or first-party evidence.
- Define the Review Scope. The subject must be reasonably connected to the reviewer’s qualifications and experience.
- Review the Exact Version. A person is not credited until the content and attribution have been approved.
- Show Accountability. Published medical content should display the contributor, reviewer where applicable, dates and sources in a reader-visible format.
- Reassess Meaningful Changes. New evidence, safety information or substantial edits may trigger renewed review.
Read the Editorial Policy and Medical Review Policy for the broader standards behind this process.
Independence, Disclosures and Corrections
Professional review and commercial approval are separate responsibilities. A contributor’s employment, ownership interests, manufacturer relationships, sponsorships or other material connections should be disclosed when relevant to the content. Disclosure does not automatically disqualify a contributor, but the relationship must be assessed and managed.
To report a factual, sourcing or attribution concern, email support@virtualsleepcare.ca with “Content correction” in the subject line. Identify the page and statement without including unnecessary personal health information. Visit the Trust Centre for editorial standards, corrections, privacy and accessibility information.
What An Expert Page Cannot Do
A biography can help you understand a contributor’s background, but it cannot tell you whether a test, diagnosis, device or treatment is appropriate for you. Website education is not emergency monitoring and does not establish a professional relationship. Use an appropriate licensed healthcare professional for individual advice; call emergency services for an emergency.
