Practical clinical training occurs primarily in these clinics where licensed NDs supervise and mentor students during clinical rotations cheap 10 mg singulair fast delivery. All the naturopathic colleges have postgraduate residency programs buy 10 mg singulair fast delivery, but currently post-graduate residency is not required as part of training and licensing. Often, graduates will join the practices of experienced clinicians before setting out on their own. Licensing and scope of practice In the USA a naturopathic physician must be licensed to practice in at least one of 11 states and two US territories (Table 2). The license is typically broad, allowing naturopathic doctors (NDs, or in some jurisdictions NMDs) to diagnose and treat disease using any natural means. In Arizona and British Columbia, acupuncture is a part of the regulated practice; elsewhere, NDs must obtain an additional license to practice acupuncture. Prescriptive drugs of natural origin, minor surgery and midwifery are permitted in many jurisdictions, and most licensed states require annual proof of continuing medical education (CME) to maintain licensure (Table 2). The requirements necessary for obtaining a license to practice include graduation from an accredited naturopathic college, passing standardized licensing examinations (Naturopathic Physicians Licensing Examination) (NPLEX), and 1 state filings and licensing fees. NPLEX is the standard examination used by all licensed US states and Canadian provinces. The first is taken after a candidate has passed basic science courses, usually after the second year of naturopathic school and includes anatomy, physiology, pathology, biochemisty, microbiology and immunology. The clinical examination is taken after graduation from an accredited naturopathic college and covers clinical training and knowledge in the various therapeutic modalities. The clinical examinations include clinical and physical diagnosis, laboratory diagnosis and diagnostic imaging, botanical medicine, pharmacology, nutrition, physical medicine, homeopathy, minor surgery, psychology and lifestyle counseling, and emergency medicine. Individual states may give additional examinations on acupuncture, minor surgery and jurisprudence.

With the more recent growth of health maintenance organizations (HMOs) best 5 mg singulair, there has been slowly evolving inclusion of chiropractors in many of these plans discount 4mg singulair free shipping. Some have restricted access strictly on the basis of referral from primary care providers, while a growing number of plans permit self-referral, usually under a system of strict guidelines for numbers of treatments. Integration of chiropractic into the US armed services is proceeding after the conclusion of a pilot program exploring the feasibility of such involvement. Additionally, the US Veterans Administration health-care system will be incorporating chiropractors, although the precise nature of this involvement is still being established. In the early 1990s the primary sources of payment for chiropractic services included 6 private insurance and direct payments from the patient. Other forms of payment, including Medicaid and managed care, contributed the remaining 10%. However, with the growing integration of chiropractic services into 10 managed care, the portion related to HMOs is expected to grow significantly. There has been considerable debate, both inside and outside the profession, regarding the role(s) chiropractors should play in the health-care delivery system. The most common way in which chiropractors practice is as limited musculoskeletal specialists, dealing primarily with painful conditions either independently or, increasingly, as part of an interdisciplinary team. There are those within the profession who advocate chiropractors as primary health-care gatekeepers with a particular emphasis on ambulatory musculoskeletal conditions. There are some chiropractors still advocating a broad practice as general primary (alternative/complementary) health-care providers not limited 13,14 to musculoskeletal conditions. Although all three of the sepractice models can be found within the chiropractic profession, all studies have shown that chiropractors treat a limited array of conditions, with up to two-thirds of patients presenting with low back 6,12,15 pain. Chiropractic has become so commonly utilized and tightly woven into the fabric of health care in the USA that some have argued that it has entered the health-care 14,16–18 mainstream. Indeed, there are a growing number of examples of integration of chiropractic services into medical clinics and HMOs. Chiropractors are permitted membership in all major spine societies including the North American Spine Society, the American Back Society and the International Society for the Study of the Lumbar Spine, and there is a recently formed society specifically to encourage co-operation between chiropractors and neurosurgeons. Even when chiropractic services are not performed as an integrated part of medical care for their condition, most patients utilize chiropractic services in combination with traditional medical care.
