A workers’ compensation study conducted in Utah by Kelly B. Jarvis,
D.C., Reed B. Phillips, D.C., Ph.D., and Elliot K. Morris, JD, MBA, compared the cost of chiropractic care to the costs of medical care for conditions with identical diagnostic codes. Results were reported in the August
1991 Journal of Occupational Medicine. The study indicated that costs were significantly higher for medical claims than for chiropractic claims; in addition, the number of work days lost was nearly ten times higher for those who received medical care instead of chiropractic care.
