Ontario Proposes Evidenced-Based Changes To Vitamin D Testing

McGuinty Government Moves Forward On Excellent Care for All Act

Ministry of Health and Long-Term Care

Ontario is listening to expert medical advice and proposing to curb unnecessary Vitamin D testing for otherwise healthy people.

In June, Ontario's Health Technology Advisory Committee concluded that the routine use of Vitamin D testing for the general population could not be justified based on current evidence.  This builds on other recent medical expert evidence that recommended changes to sleep studies, bone mineral density and pre-operative testing for cataract surgery.

Since 2004, Vitamin D testing has grown by 2,500 per cent - jumping from 29,000 tests to over 700,000 in 2009.  Moving toward evidence based testing supports Ontario's Excellent Care for All agenda to ensure health care investments are getting results and improving patient care. The proposed change to Vitamin D testing would result in resources being redirected to other laboratory services.

The province would continue to cover Vitamin D testing for patients where medical evidence indicates there is a need.  Ontario would continue to fund tests for patients with medical conditions such as Osteoporosis, Rickets, Osteopenia, Malabsorption Syndromes and Renal Disease.  Ontarians who are on medications that affect Vitamin D metabolism would also still be covered. 

The public is invited to comment on the proposed change to Vitamin D testing which will be posted on Ontario's regulatory registry until September 26. 

In June, Ontario passed the Excellent Care for All Act, which lays the foundation for these improvements and is part of the Open Ontario Plan to improve the quality and value of health care.

Quick Facts

  • This year it is expected that the government will be billed up to $66 million on Vitamin D tests compared to $1.7 million in 2004.
  • If current trends continue, billings could reach up to $155 million by 2011/12.
  • Manitoba, Nova Scotia, Newfoundland, Prince Edward Island, Labrador and Saskatchewan have all moved to limit unnecessary Vitamin D testing.

“We must use our health care dollars for services that are demonstrated to improve the health of Ontarians. We need to make sure those who need tests get them, and ensure that precious health care dollars are invested in care that is evidence-based.”

Minister of Health and Long-Term Care

“All evidence shows that routine Vitamin D testing is not warranted in the average risk population. Instead, we recommend that Ontarians who feel they are Vitamin D deficient should follow Health Canada's guidelines to increase their levels of Vitamin D.”
