With 60,000 practicing chiropractors, they comprise the third-largest group of health care providers in the United States after physicians and dentists. It is the largest and fastest-growing group of complementary and alternative medicine (CAM) providers in the United States, and its ranks are projected to nearly double by 2010. One in three persons with low back pain sees a chiropractor, amounting to 190 million patient visits per year. This figure has doubled in the past 15-20 years.1 Most patients self-refer with only 3% of patients being referred by MDs. Most insurance carriers, including Medicare, cover chiropractic. Some plans now require a referral from a MD for coverage of the service. Several studies have attempted to determine what makes some patients with back pain seek chiropractic instead of or in addition to conventional medical care. Results have been inconsistent2-4 except for the finding that chiropractic use is associated with having insurance that covers the service or having no health insurance at all.3,4
A national telephone survey conducted in 1997 (n = 2,055) showed that 29% of those interviewed used some type of CAM therapy to treat back and neck pain, 25% used CAM in additional to a conventional provider, and 34% used neither.5 Chiropractic was the most commonly reported CAM therapy used at 20%.6 Women were more likely than men to use CAM providers to treat neck or back pain. In this same sample, conventional practitioners were perceived by 27% to have been "very helpful" in treating their neck or back pain while chiropractors were rated as very helpful in 62% of cases.6
Several randomized controlled and observational trials have examined patient satisfaction with chiropractic vs. medical care for low back pain. They have consistently found that patients prefer chiropractic care to that offered by physicians.4,7-11 Satisfaction levels are better or similar to those reported by patients receiving care for low back pain from physical therapists.9,12
A large randomized controlled trial (UCLA Low Back Pain Study) examined which factors accounted for the difference in satisfaction between chiropractic and medical patients with low back pain.9 In their cohort of 672 patients, satisfaction was significantly greater in the patients randomized to receive chiropractic care (P < 0.001). The difference in satisfaction was accounted for almost entirely by the patients' reports of having received an explanation of treatment and self-care advice. This finding is not surprising when one considers that 85% of patients with isolated low back pain are not given a precise pathoanatomical diagnosis within the conventional medical framework.13
