Evaluation of United States chiropractic professional subgroups: a survey of randomly sampled chiropractors

Background Professional subgroups are common and may play a role in aiding professional maturity or impeding professional legitimization. The chiropractic profession in the United States has a long history of diverse intra-professional subgroups with varying ideologies and practice styles. To our knowledge, large-scale quantification of chiropractic professional subgroups in the United States has not been conducted. The purpose of this study was to quantify and describe the clinical practice beliefs and behaviors associated with United States chiropractic subgroups. Methods A 10% random sample of United States licensed chiropractors (n = 8975) was selected from all 50 state regulatory board lists and invited to participate in a survey. The survey consisted of a 7-item questionnaire; 6 items were associated with chiropractic ideological and practice characteristics and 1 item was related to the self-identified role of chiropractic in the healthcare system which was utilized as the dependent variable to identify chiropractic subgroups. Multinomial logistic regression with predictive margins was used to analyze which responses to the 6 ideology and practice characteristic items were predictive of chiropractic subgroups. Results A total of 3538 responses were collected (39.4% response rate). Respondents self-identified into three distinct subgroups based on the perceived role of the chiropractic profession in the greater healthcare system: 56.8% were spine/neuromusculoskeletal focused; 22.0% were primary care focused; and 21.2% were vertebral subluxation focused. Patterns of responses to the 6 ideologies and practice characteristic items were substantially different across the three professional subgroups. Conclusions Respondents self-identified into one of three distinct intra-professional subgroups. These subgroups can be differentiated along themes related to clinical practice beliefs and behaviors.

Looking back at the lawsuit that transformed the chiropractic profession: Overview

The purpose of this paper is to provide a brief overview of Looking Back at the Lawsuit That Transformed the Chiropractic Profession, which is a series of 8 research papers that explore the historical events surrounding the Wilk v American Medical Association lawsuit and how these events may have had an influence on the chiropractic profession.

Looking back at the lawsuit that transformed the chiropractic profession part 2: Rise of the American Medical Association

Objective This paper is the second in a series that explores the historical events surrounding the Wilk v American Medical Association (AMA) lawsuit in which the plaintiffs argued that the AMA, the American Hospital Association, and other medical specialty societies violated anti-trust law by restraining chiropractors' business practices. The purpose of this paper is to provide a brief review of the history of how the AMA rose to dominate health care in the United States, and within this social context, how the chiropractic profession fought to survive in the first half of the 20th century. Methods This historical research study used a phenomenological approach to qualitative inquiry into the conflict between regular medicine and chiropractic and the events before, during, and after a legal dispute at the time of modernization of the chiropractic profession. Our methods included obtaining primary and secondary data sources. The final narrative recount was developed into 8 papers following a successive timeline. This paper is the second of the series that explores the growth of medicine and the chiropractic profession. Results The AMA's code of ethics established in 1847 continued to direct organized medicine's actions to exclude other health professions. During the early 1900s, the AMA established itself as “regular medicine.” They labeled other types of medicine and health care professions, such as chiropractic, as “irregulars” claiming that they were cultists and quacks. In addition to the rise in power of the AMA, a report written by Abraham Flexner helped to solidify the AMA's control over health care. Chiropractic as a profession was emerging and developing in practice, education, and science. The few resources available to chiropractors were used to defend their profession against attacks from organized medicine and to secure legislation to legalize the practice of chiropractic. After years of struggle, the last state in the US legalized chiropractic 79 years after the birth of the profession. Conclusion In the first part of the 20th century, the AMA was amassing power as chiropractic was just emerging as a profession. Events such as publication of Flexner's report and development of the medical basic science laws helped to entrench the AMA's monopoly on health care. The health care environment shaped how chiropractic grew as a profession. Chiropractic practice, education, and science were challenged by trying to develop outside of the medical establishment. These events added to the tensions between the professions that ultimately resulted in the Wilk v AMA lawsuit.

Looking back at the lawsuit that transformed the chiropractic profession part 8: Judgment impact

Objective This paper is the eighth in a series that explores the historical events surrounding the Wilk v American Medical Association (AMA) lawsuit in which the plaintiffs argued that the AMA, the American Hospital Association, and other medical specialty societies violated antitrust law by restraining chiropractors' business practices. The purpose of this paper is to discuss the possible impact that the final decision in favor of the plaintiffs may have had on the chiropractic profession. Methods This historical research study used a phenomenological approach to qualitative inquiry into the conflict between regular medicine and chiropractic and the events before, during, and after a legal dispute at the time of modernization of the chiropractic profession. Our methods included obtaining primary and secondary data sources. The final narrative recount was developed into 8 papers following a successive timeline. This paper is the eighth of the series that discusses how the trial decision may have influenced the chiropractic that we know today in the United States. Results Chiropractic practice, education, and research have changed since before the lawsuit was filed. There are several areas in which we propose that the trial decision may have had an impact on the chiropractic profession. Conclusion The lawsuit removed the barriers that were implemented by organized medicine against the chiropractic profession. The quality of chiropractic practice, education, and research continues to improve and the profession continues to meet its most fundamental mission: to improve the lives of patients. Chiropractors practicing in the United States today are allowed to collaborate freely with other health professionals. Today, patients have the option to access chiropractic care because of the dedicated efforts of many people to reduce the previous barriers. It is up to the present-day members of the medical and chiropractic professions to look back and to remember what happened. By recalling the events surrounding the lawsuit, we may have a better understanding about our professions today. This information may help to facilitate interactions between medicine and chiropractic and to develop more respectful partnerships focused on creating a better future for the health of the public. The future of the chiropractic profession rests in the heads, hearts, and hands of its current members to do what is right.

Looking back at the lawsuit that transformed the chiropractic profession part 5: Evidence exposed

Objective This is the fifth article in a series that explores the historical events surrounding the Wilk v American Medical Association (AMA) lawsuit in which the plaintiffs argued that the AMA, the American Hospital Association, and other medical specialty societies violated antitrust law by restraining chiropractors' business practices. The purpose of this article is to provide a brief review of events surrounding the eventual end of the AMA's Committee on Quackery and the exposure of evidence of the AMA's efforts to boycott the chiropractic profession. Methods This historical research study used a phenomenological approach to qualitative inquiry into the conflict between regular medicine and chiropractic and the events before, during, and after a legal dispute at the time of modernization of the chiropractic profession. Our methods included obtaining primary and secondary data sources. The final narrative recount was developed into 8 articles following a successive timeline. This article, the fifth of the series, explores the exposure of what the AMA had been doing, which provided evidence that was eventually used in the Wilk v AMA antitrust lawsuit. Results The prime mission of the AMA's Committee on Quackery was “first, the containment of chiropractic and, ultimately, the elimination of chiropractic.” However, the committee did not complete its mission and quietly disbanded in 1974. This was the same year that the chiropractic profession finally gained licensure in all 50 of the United States; received recognition from the US Commissioner of Education, Department of Health, Education and Welfare; and was successfully included in Medicare. In 1975, documents reportedly obtained by the Church of Scientology covert operatives under Operation AMA Doom revealed the extent to which the AMA and its Committee on Quackery had been working to contain and eliminate the chiropractic profession. The AMA actions included influencing mainstream media, decisions made by the Joint Commission on Accreditation of Hospitals, and the Department of Health, Education, and Welfare. Other actions included publishing propaganda against chiropractic and implementing an anti-chiropractic program aimed at medical students, medical societies, and the American public. Conclusion After more than a decade of overt and covert actions, the AMA chose to end its Committee on Quackery. The following year, documents exposed the extent of AMA's efforts to enact its boycott of chiropractic.

Looking back at the lawsuit that transformed the chiropractic profession part 6: Preparing for the lawsuit

Objective This is the sixth article in a series that explores the historical events surrounding the Wilk v American Medical Association (AMA) lawsuit in which the plaintiffs argued that the AMA, the American Hospital Association, and other medical specialty societies violated antitrust law by restraining chiropractors' business practices. The purpose of this article is to provide a brief review of the plaintiffs, lead lawyer, and the events immediately before the lawsuit was filed. Methods This historical research study used a phenomenological approach to qualitative inquiry into the conflict between regular medicine and chiropractic and the events before, during, and after a legal dispute at the time of modernization of the chiropractic profession. Our methods included obtaining primary and secondary data sources. The final narrative recount was developed into 8 articles following a successive timeline. This article, the sixth of the series, explores the plaintiffs' stories. Results Because of the AMA's boycott on chiropractic, chiropractors were not able to collaborate with medical physicians or refer patients to medical facilities, which resulted in restricted trade and potential harm to patients' well-being. The plaintiffs, Patricia Arthur, James Bryden, Michael Pedigo, and Chester Wilk, came from different regions of the United States. Each had unique experiences and were compelled to seek justice. The lead lawyer, Mr George McAndrews, was the son of a chiropractor and had witnessed the effect that the AMA's attacks on chiropractic had on his father. It took several years to gather enough resources to file the suit, which was submitted in 1976. Conclusion The conflicts that the plaintiffs experienced stimulated them to pursue a lawsuit against the AMA and other organized political medicine groups.

Looking back at the lawsuit that transformed the chiropractic profession part 7: Lawsuit and decisions

Objective This is the seventh paper in a series that explores the historical events surrounding the Wilk v American Medical Association (AMA) lawsuit in which the plaintiffs argued that the AMA, the American Hospital Association, and other medical specialty societies violated antitrust law by restraining chiropractors' business practices. The purpose of this paper is to provide a summary of the lawsuit that was first filed in 1976 and concluded with the final denial of appeal in 1990. Methods This historical research study used a phenomenological approach to qualitative inquiry into the conflict between regular medicine and chiropractic and the events before, during, and after a legal dispute at the time of modernization of the chiropractic profession. Our methods included obtaining primary and secondary data sources. The final narrative recount was developed into 8 papers following a successive time line. This paper, the seventh of the series, considers the information of the 2 trials and the judge's decision. Results By the time the first trial began in 1980, the AMA had already changed its anti-chiropractic stance to allow medical doctors to associate with chiropractors if they wished. In the first trial, the chiropractors were not able to overcome the very stigma that organized medicine worked so hard to create over many decades, which resulted in the jury voting in favor of the AMA and other defendants. The plaintiffs, Drs Patricia Arthur, James Bryden, Michael Pedigo, and Chester Wilk, continued with their pursuit of justice. Their lawyer, Mr George McAndrews, fought for an appeal and was allowed a second trial. The second trial was a bench trial in which Judge Susan Getzendanner declared her final judgment that “the American Medical Association (AMA) and its members participated in a conspiracy against chiropractors in violation of the nation's antitrust laws.” After the AMA's appeal was denied by the Court of Appeals for the Seventh Circuit in 1990, the decision was declared permanent. The injunction that was ordered by the judge was published in the January 1, 1988, issue of the Journal of the American Medical Association. Conclusion The efforts by Mr McAndrews and his legal team and the persistence of the plaintiffs and countless others in the chiropractic profession concluded in Judge Getzendanner's decision, which prevented the AMA from rebuilding barriers or developing another boycott. The chiropractic profession was ready to move into its next century.

Looking back at the lawsuit that transformed the chiropractic profession part 4: Committee on Quackery

Objective This is the fourth article in a series that explores the historical events surrounding the Wilk v American Medical Association (AMA) lawsuit, in which the plaintiffs argued that the AMA, the American Hospital Association, and other medical specialty societies violated antitrust law by restraining chiropractors' business practices. The purpose of this article is to provide a brief review of the history of the origins of AMA's increased efforts to contain and eliminate the chiropractic profession and the development of the Chiropractic Committee, which would later become the AMA Committee on Quackery. Methods This historical research study used a phenomenological approach to qualitative inquiry into the conflict between regular medicine and chiropractic and the events before, during, and after a legal dispute at the time of modernization of the chiropractic profession. Our methods included obtaining primary and secondary data sources. The final narrative recount was developed into 8 articles following a successive timeline. This article is the fourth of the series that explores the origins of AMA's increased efforts to contain and eliminate the chiropractic profession. Results In the 1950s, the number of chiropractors grew in Iowa, and chiropractors were seeking equity with other health professions through legislation. In response, the Iowa State Medical Society created a Chiropractic Committee to contain chiropractic and prompted the creation of the “Iowa Plan” to contain and eliminate the chiropractic profession. The AMA leadership was enticed by the plan and hired the Iowa State Medical Society's legislative counsel, who structured the operation. The AMA adopted the Iowa Plan for nationwide implementation to eradicate chiropractic. The formation of the AMA's Committee on Chiropractic, which was later renamed the Committee on Quackery (CoQ), led overt and covert campaigns against chiropractic. Both national chiropractic associations were fully aware of many, but not all, of organized medicine's plans to restrain chiropractic. Conclusion By the 1960s, organized medicine heightened its efforts to contain and eliminate the chiropractic profession. The intensified campaign began in Iowa and was adopted by the AMA as a national campaign. Although the meetings of the AMA committees were not public, the war against chiropractic was distributed widely in lay publications, medical sources, and even chiropractic journals. Details about events would eventually be more fully revealed during the Wilk v AMA trials.
