The growing role of chiropractic in health care delivery

The number of U.S. chiropractors grew by two-thirds between 1978 and 1988, and new data show that more than 5 percent of Americans used chiropractic during a six-quarter period, spending an annual average of $411. As U.S. policymakers debate creation of standard or minimum benefit packages, these new findings may help to determine whether chiropractic meets the criteria of clinical efficacy and cost-effectiveness.
