The CAM movement and the integration of quality health care: the case of chiropractic.

High and increasing consumer demand for complementary and alternative medicine (CAM) services necessitates a concerted focus to determine the effectiveness of such practices and to ensure that future possible integration of CAM with conventional medicine is founded on sound evidence-based principles of quality health care delivery. The example of chiropractic provides useful insights to guide further research and integration of evidence-based CAM into mainstream health care in the United States. A critical point of departure for this area of inquiry is identifying and addressing barriers to conducting scientifically sound and meaningful cross-disciplinary, practice-based research.
