“All the forces in the world are not so powerful as an idea whose time has come.” — Victor Hugo (Feb. 26, 1802 - May 22, 1885)

THE TIME HAS COME TO EXTEND THE CHIROPRACTIC PROFESSION’S REACH beyond that of being a mere option, among many, in spine-related care or just a provider of a particular form of treatment. Our opportunity to gain cultural authority has never been better. A patient’s need for impartial, scientifically valid, yet pragmatic cognitive guidance has never been greater.

Today’s patient faces a spine care system that is chaotic, ineffective and expensive. It can also be dangerous and unscrupulous. Benefits of treatments are often overstated.(1) Technology is introduced with little scientific evidence of effectiveness. (1,2) Potential harms are underreported or misrepresented.(1,3) And conflicts of interest, potentially compromising patient safety and cost, often remain undisclosed.(4,5,6,7)

Drs. Scott Haldeman and Simon Dagenais poignantly illustrated this chaos, likening our system to a “Supermarket of Spine Care.”(1) With more than 200 different treatment options, the supermarket is large. With more than 23 different clinicians offering their particular brand of care, it is filled with diverse and often conflicting opinions. Such disparity was also pointed out by Richard Deyo, MD, who stated, “There are wide variations in spine care, a fact that suggests there is professional uncertainty about the optimal approach.”(8)

Guidelines, first introduced in the United States in 1994, attempted to address such variability with an evidence-based approach.(9) Since then, at least 11 additional international guidelines have been developed, most of which are generally similar.(10) Despite the presence of these, studies have shown that they are often ignored, particularly by family physicians, leading to higher costs, increased use of narcotic medication and greater risks of adverse events.(11,12) Additional data have also illustrated the frequent inappropriate use of MRIs by general practitioners, resulting in a greater chance of surgery, larger costs per episode of care and no improvement in clinical outcomes.(13,14,15)

Interprofessional collaboration, found to enhance patient outcomes in other clinical settings, (16,17) would appear to be necessary for clinically and economically efficient spine-related care. However, such collaboration may be more illusory than real as, similar to other clinical environments, (18,19) integrated and collaborative spine care is impeded by territoriality and turf wars. (20,21) As noted earlier, there are more than 23 different clinical professionals involved in spine-related care. Most, if not all, of these focus primarily on providing care, as opposed to guiding care. This alone raises the question of how bias for one preferred form of care over another may affect any recommendations.

Confirmation Bias

In 1620, Sir Frances Bacon stated, “The human understanding, when it has once adopted an opinion, draws all things else to support and agree with it.(22) Such “confirmation bias,” or the tendency of individuals to favor information supporting their own beliefs,(23) has been shown to obstruct objectivity in spine research and treatment decisions, especially when one has a vested interest in what one is doing or researching.(24,25)

Perhaps nowhere else is the evidence of spinecare chaos more alarming than at the intersection of commercial entrepreneurialism and the implementation of spine-related “technophilia.” As noted previously, many forms of technology today are introduced with little scientific evidence of effectiveness, plus using misleading advertising and kickbacks to physicians. In his book Stabbed in the Back, Dr. Norton Hadler writes how “entrepreneurial relationships that might compromise the choice of what’s best for one’s patients walk a very fine line between the sanctioned and the illegal.”(4) As an example, he relates the $40 million whistle-blower lawsuit against device manufacturer Medtronic for allegedly paying kickbacks to induce surgeons to use its spinal implants. Dr. Eugene Caragee investigated another Medtronic product, Infuse (used to enhance spinal fusion), and noted that the risk of adverse events was 10 to 15 times greater than original estimates reported in industry-sponsored peer review publications.(26)

Other studies have reinforced Caragee’s research with a more recent report stating, “There is mounting evidence in the spinal literature that utilizing BMP/INFUSE in spinal fusions contributes to major perioperative and postoperative morbidity.”(27) To its credit, Medtronic did commission a completely independent study of this product with the results carrying a mixed message. Lead investigator Dr. Harlan Krumholz stated, “There is a tremendous amount of uncertainty about the benefit it provides and how safe it is. I remain concerned that products like these are approved with too little study before they reach the market and too little afterward.”(28)

Commercialization of Spine Care

Such commercialization of spine-related care has even greater reach extending to common services such as imaging and injections. Mitchell has shown that imaging, epidural steroid injections and even complex surgeries are significantly higher when physicians have a vested financial interest in the facility performing the procedures.(29) The need for intellectual integrity becomes even more palpable when procedures such as epidural steroids, felt by many to be extremely safe, are found to be associated with the potential risk of brain edema and seizures.(30) Also, Jack Stern, MD, a writer for the North American Spine Society, states, “To date, laser discectomy may be more effective in attracting patients than in treating them.” (31,32,33,34)

Moving beyond the promotional hype that often supersedes reality, our current system of spinecare delivery has failed. Between 2000 and 2007, the prevalence of back pain has increased by 29 percent. Chronic back pain has increased by 64 percent, and per-person spine expenditures were 73 percent greater in the United States as compared with other industrialized societies.35 Between 1997 and 2005, total spending rose 65 percent, yet the percentage of patients with impaired spinal function, including total disability, has increased.(36,37) Even first-time spine pain patients face increased risks with estimates that up to 45 percent of such individuals may experience a less than optimum outcome.(38)

Chiropractic Cost-Effectiveness

All spine-care professionals bear some responsibility for the inadequacy of our current system. However, if a recent study on Medicare utilization of chiropractic exemplifies what occurs with non- Medicare insurance plans, we may contribute more to this problem by our absence than our presence. This study showed that between 2005 and 2008, Medicare spending for chiropractic decreased by 17 to 18 percent, in contrast to a 10 to 16 percent growth in spending for other Medicare services and that chiropractic accounted for less than onetenth of 1 percent of overall Medicare spending.(39)

Chiropractic care, like other interventions for spinal pain, suffers from a lack of unequivocal evidence of effectiveness. A recent Cochrane review on acute and sub-acute back pain showed chiropractic care resulted in improved short- and medium-term pain and disability but no substantial benefit as compared with other interventions on long-term outcomes.(40) Another Cochrane review of chiropractic and chronic back pain concluded that, “in general, there is high-quality evidence that SMT has a small, statistically signifi- cant but not clinically relevant, short-term effect on pain relief and functional status as compared to other interventions.”(41) These citations are not meant to disparage chiropractic care, but rather to illustrate the difficulty in obtaining unequivocal proof of effectiveness with any intervention.

With so much attention being placed on researching our specific method of treatment (spinal manipulation), what seems to be less recognized is the potential benefit of our collective thought processes and how these positively affect patient outcomes. Several studies have provided such evidence, but possibly more tangentially than directly. For example, two different papers by Stanos et al. demonstrated that overall medical costs were much less for patients initiating their care with a DC as compared with an MD or DO, noting that the total cost difference was approximately $1,000 over a two-year period and attributed to lower in patient utilization.(42,43) Phelan et al. examined data from more than 100,000 work injury claims and found that less than 1 percent were treated by DCs and that their average expense for treatment was $663 as compared with a “medical care” average of $3,519.44 Brooks et al. more recently added to this literature by also demonstrating a significant reduction in overall health-related costs when “CAM” providers are utilized, once again attributing this to less utilization of inpatient services.(45)

Joan Didion has stated, “Most of our platitudes notwithstanding, self-deception remains the most difficult deception.”(46) Much of today’s medical approach toward spine care remains caught in this trap, seduced by a “belief” in technology, despite outcomes calling for a dramatically different approach.

It is here where knowledge and intellectual integrity can assist our patients in navigating a complicated field of options and in so doing gain greater levels of cultural authority. As a profession, we are far greater than our techniques.

Our minds would be a terrible thing to waste.

More on Chiropractic Cultural Authority

TWO INFORMATIVE ARTICLES ON CHIROPRACTIC CULTURAL AUTHORITY are worthy of examination. In a 2008 article, the authors compare chiropractic to podiatry and note:

By focusing on a specific set of clinical problems (i.e., foot disorders) for which society had a demonstrable need for professional services, using the scientific method to explore ways to better serve society, consistently upgrading their clinical training, and appropriately policing themselves, podiatrists have successfully fulfilled the social contract. As a result, it is our experience that podiatrists are widely perceived by the public to be ethical and honest professionals who generally have their patient's best interests at heart.

The chiropractic profession has an obligation to actively divorce itself from metaphysical explanations of health and disease, as well as to actively regulate itself in refusing to tolerate fraud, abuse and quackery, which are more rampant in our profession than in other healthcare professions. This must be done on an individual practitioner basis as well as by the political, educational and regulatory bodies. In this way, the profession can fulfill its responsibility to the social contract. This will dramatically increase the level of trust in and respect for the profession from society at large.

Ronald D. Fudala, DC, DACAN, graduated from the National University of Health Sciences in Lombard, Ill, in 1987. Dr. Fudala was neurology chairman for the Ohio State Chiropractic Association and served on its peer review and college site approval committees. In 1995, he received OSCA’s “Chiropractor of the Year” award.

In January 2001, Dr. Fudala was invited to join the neurosurgical division of a large specialty referral practice where he remained until August 2011. During this time, he developed and supervised a structural spine care program for nonsurgical and postsurgical patients. He resigned from this practice to devote a greater portion of time to independent study, postgraduate teaching and providing oneon- one personal consulting to patients, businesses and other doctors. Dr. Fudala was a board member and educational chairman for the International Board of Electrodiagnosis and currently serves on the educational committee for the International Academy of Chiropractic Neurologists.
