Journal of Chiropractic Humanities: A Celebration of 25 Volumes.

This article reflects on the origins of the Journal of Chiropractic Humanities. The journal was born at a time when the chiropractic profession had few journals but needed a publication to capture evolving philosophical constructs.

In response to "The Knowledge of Our Knowledge": a reflection on McAndrews' view of epistemology.

This commentary considers one of the articles published in the first volume of this journal and reflects on the status of research and knowledge at that time. The chiropractic profession has witnessed advancement in the use of the scientific method in the past several decades, and scholarly journals have helped support this substantial growth.

Clinical utilization and cost outcomes from an integrative medicine independent physician association: an additional 3-year update.

OBJECTIVE: Our initial report analyzed clinical and cost utilization data from the years 1999 to 2002 for an integrative medicine independent physician association (IPA) whose primary care physicians (PCPs) were exclusively doctors of chiropractic. This report updates the subsequent utilization data from the IPA for the years 2003 to 2005 and includes first-time comparisons in data points among PCPs of different licensures who were oriented toward complementary and alternative medicine (CAM). METHODS: Independent physician association-incurred claims and stratified random patient surveys were descriptively analyzed for clinical utilization, cost offsets, and member satisfaction compared with conventional medical IPA normative values. Comparisons to our original publication's comparative blinded data, using nonrandom matched comparison groups, were descriptively analyzed for differences in age/sex demographics and disease profiles to examine sample bias. RESULTS: Clinical and cost utilization based on 70,274 member-months over a 7-year period demonstrated decreases of 60.2% in-hospital admissions, 59.0% hospital days, 62.0% outpatient surgeries and procedures, and 85% pharmaceutical costs when compared with conventional medicine IPA performance for the same health maintenance organization product in the same geography and time frame. CONCLUSION: During the past 7 years, and with a larger population than originally reported, the CAM-oriented PCPs using a nonsurgical/nonpharmaceutical approach demonstrated reductions in both clinical and cost utilization when compared with PCPs using conventional medicine alone. Decreased utilization was uniformly achieved by all CAM-oriented PCPs, regardless of their licensure. The validity and generalizability of this observation are guarded given the lack of randomization, lack of statistical analysis possible, and potentially biased data in this population.

Patient perceptions of chiropractic treatment for primary care disorders.

OBJECTIVE: Although some surveyed groups of chiropractors consider themselves qualified as primary care providers, consumer attitudes of such may affect practice success. The purpose of this study is to determine chiropractic patients' perception of chiropractors as primary care providers and to determine what disorders patients believe chiropractors can treat. METHODS: A 2-page survey was developed to collect information from current chiropractic patients at a teaching chiropractic clinic in the United States. Questions included (1) brief patient demographic information, (2) whether their chiropractor was their primary care physician, and (3) patient beliefs about chiropractors assessing and treating conditions that are common to a primary care medical practice. Conditions listed in the survey were based on a previous study on primary care medical physicians' practices. The sample of chiropractic patients was divided into suburban, urban, and chiropractic university-affiliated patients. RESULTS: There were 163 subjects who responded to this survey for a 58% response rate. Only 19% (30/157) saw their chiropractor as their primary care physician. However, for each 'primary care condition' listed, the percent of patients who affirmed that chiropractors could treat the condition varied greatly with many conditions showing an affirmative response of higher than 50% especially in the urban and university-affiliated patient groups. All patients overwhelmingly believed that chiropractors could treat musculoskeletal conditions. CONCLUSIONS: Patients have varied views of what chiropractors can and cannot treat. Further studies are needed to determine the effectiveness of chiropractic treatment for specific primary care disorders. The results of such studies may be the determining influence for public and physician opinion on the appropriateness of chiropractic care for these conditions.

Subluxation: dogma or science?

Subluxation syndrome is a legitimate, potentially testable, theoretical construct for which there is little experimental evidence. Acceptable as hypothesis, the widespread assertion of the clinical meaningfulness of this notion brings ridicule from the scientific and health care communities and confusion within the chiropractic profession. We believe that an evidence-orientation among chiropractors requires that we distinguish between subluxation dogma vs. subluxation as the potential focus of clinical research. We lament efforts to generate unity within the profession through consensus statements concerning subluxation dogma, and believe that cultural authority will continue to elude us so long as we assert dogma as though it were validated clinical theory.

Clinical and cost outcomes of an integrative medicine IPA.

OBJECTIVE: We hypothesized that primary care physicians (PCPs) specializing in a nonpharmaceutical/nonsurgical approach as their primary modality and utilizing a variety of complementary/alternative medicine (CAM) techniques integrated with allopathic medicine would have superior clinical and cost outcomes compared with PCPs utilizing conventional medicine alone. DESIGN: Incurred claims and stratified randomized patient surveys were analyzed for clinical outcomes, cost offsets, and member satisfaction compared with normative values. Comparative blinded data, using nonrandomized matched comparison groups, was analyzed for age/sex demographics and disease profiles to examine sample bias. SETTING: An integrative medicine independent provider association (IPA) contracted with a National Committee for Quality Assurance (NCQA)-accredited health maintenance organization (HMO) in metropolitan Chicago. SUBJECTS: All members enrolled with the integrative medicine IPA from January 1, 1999 through December 31, 2002. RESULTS: Analysis of clinical and cost outcomes on 21,743 member months over a 4-year period demonstrated decreases of 43.0% in hospital admissions per 1000, 58.4% hospital days per 1000, 43.2% outpatient surgeries and procedures per 1000, and 51.8% pharmaceutical cost reductions when compared with normative conventional medicine IPA performance for the same HMO product in the same geography over the same time frame. CONCLUSION: In the limited population studied, PCPs utilizing an integrative medical approach emphasizing a variety of CAM therapies had substantially improved clinical outcomes and cost offsets compared with PCPs utilizing conventional medicine alone. While certainly promising, these initial results may not be consistent on a larger and more diverse population.

Evaluation of transforaminal ligaments by magnetic resonance imaging.

OBJECTIVES: Three-part study to (1) identify and describe transforaminal ligaments (TFLs), (2) determine the best low-field-strength magnetic resonance imaging (MRI) technique for TFLs, and (3) determine the ability of low-field-strength MRI to obtain images of TFLs. DESIGN: Part I-descriptive anatomic study; part II-descriptive MRI study; part III-blinded comparison of diagnostic test against gold standard (MRI vs anatomic dissection). SETTING: Chiropractic college gross anatomy laboratory and MRI facilities. SPECIMENS: Three anatomic specimens of male cadavers age 60 to 85 years; a fourth specimen was used for training radiologists in part III. MAIN OUTCOME MEASURES: Part I-number and size of TFLs; part II-subjective grading of highest quality MRI images; part III-specificity, sensitivity, positive predictive value, negative predictive value, percent agreement, and accuracy of identifying TFLs from MRI scans. MAIN RESULTS: Part I-19 TFLs identified in 30 intervertebral foramina (IVFs) (60% of IVFs had TFLs), thick = 4 (21%), medium thickness = 12 (63.2%), thin = 3 (15.8%); part II-TFLs demonstrated to best advantage with pure sagittal plane, T(1)-weighted MRI; part III-average: specificity = 88.9%, sensitivity = 45.6%, positive predictive value = 86.7%, negative predictive value = 50.8%, percent agreement = 78%, and accuracy = 62.4%. CONCLUSIONS: The number of TFLs was in general agreement with previous research. Images of TFLs can be successfully imaged with low-field-strength MRI. If a trained radiologist identifies a TFL, there is an 87% chance that one is present, and if a trained radiologist does not identify a TFL in an intervertebral foramen, there remains a 51% chance that one is present.
