A major study to assess the most appropriate use of available health care resources was reported in 1993. This was an outcome of a study funded by the Ontario Ministry of Health and conducted in hopes of sharing information about ways to reduce the incidence of work-related injuries and to address cost-effective ways to rehabilitate disabled and injured workers.

The study was conducted by three health economists led by University of Ottawa Professor Pran Manga, Ph. D. The 216-page report of the study is commonly called the Manga Report. The Manga Report overwhelmingly supported the efficacy, safety, scientific validity, and cost-effectiveness of chiropractic for low-back pain. Additionally, it found that higher patient satisfaction levels were associated with chiropractic care than with medical treatment alternatives.

“Evidence from Canada and other countries suggests potential savings of hundreds of millions annually,” the Manga Report states. “The literature clearly and consistently shows that the major savings form chiropractic management come from fewer and lower costs of auxiliary services, fewer hospitalizations, and a highly significant reduction in chronic problems, as well as in levels and duration of disability.
