Cochrane Collaboration brings balanced, up-to-date health information to Canadians


Ever wondered if cleaning a wound with water really helps prevent infection? Or if vitamin C has any effect on the common cold? Or if tai chi can help in treating rheumatoid arthritis? These are just a few of the questions addressed in Cochrane reviews, which are well known for providing the “gold standard” of evidence in medicine.

Cochrane reviews are produced by members of the Cochrane Collaboration, an international not-for-profit organization founded in 1993. The Canadian arm of the Cochrane Collaboration is led by Dr. Jeremy Grimshaw, Senior Scientist and Director of the OHRI Clinical Epidemiology Program and Professor in the University of Ottawa Department of Epidemiology and Community Medicine.

OHRI researchers have contributed to Cochrane reviews that have answered fundamental health questions for professionals and the general public. Recent findings include:

  • Decision aids can help people take an active role in making informed decisions about healthcare options (see summary).
  • A drug called Alendronate is effective in preventing fractures in some subgroups of women with osteoporosis (see summary).
  • Oral drugs work just as well as intravaginal drugs for treatment of yeast infections (see summary).
  • There is "silver" level evidence that Tai Chi improves the range of motion of the ankle, hip and knee in people with rheumatoid arthritis (see summary).
  • Steroid injections can relieve symptoms of carpal tunnel syndrome for up to three months after treatment (see summary).
  • School meal programs increase attendance and math scores in developing countries, but results in developed countries are not as clear (see summary).
  • Some educational programs can help improve the referral process (i.e. family physician referrals to specialists), but there is little evidence of benefit from organizational or financial programs (see summary).

Currently, all Canadians can access summaries of Cochrane reviews freely on the web, but in most provinces, users are required to pay to access the full articles. Dr. Grimshaw is leading a national effort to convince the federal and provincial governments to purchase a national license to the Cochrane Library, for just 1.5 cents per citizen per year. Many other countries have negotiated licenses to the Cochrane Library, and currently more than 50 per cent of the world’s population has access.
