The positive and negative impacts of the COVID-19 pandemic on the European Council on Chiropractic Education accredited programs: A mixed methods audit and thematic analysis.

OBJECTIVE: The objectives of this study were to: (1) determine the impact of COVID-19 on the operations within the 9 sections of the European Council on Chiropractic Education (ECCE) 'Standards'; (2) identify specific rapid changes to the programs; and (3) identify positive changes that will continue post-pandemic. METHODS: This was a mixed methods audit and thematic analysis of data from interviews conducted via a cloud-based video conferencing tool with program leaders of the ECCE accredited institutions. A validated questionnaire designed around ECCE's "Standards" was used, consisting of 3 sections: (1) Severity of the COVID-19 impact on each ECCE Standard section; (2) Description of program changes made for each section; (3) Identification of positive changes continuing post-pandemic. Descriptive statistics were calculated for Part 1 and compared for significant differences via the Kruskal-Wallis test. Verbal responses to Parts 2 and 3 were evaluated independently by 3 researchers using a modified "thematic analysis" approach. Final thematic categories and themes were agreed upon by the researchers. RESULTS: There was a 100% response rate. Outpatient teaching clinics were most severely affected, followed by teaching chiropractic technique courses. Curricular structure and duration and program management were least affected (p =.033). Four thematic categories were identified: Extreme Stress, Courses Most Severely Affected, Integrity of Examinations and Assessments, and Positive Changes That Will Continue. CONCLUSION: Final-year students were most negatively impacted due to restricted opportunities in outpatient clinics. Integrity of examinations was also a problem. Positive, innovative teaching materials and methods were quickly developed and should continue.

The Councils on Chiropractic Education International Mapping Project: Comparison of Member Organizations' Educational Standards to the Councils on Chiropractic Education International Framework Document.

Objective: The purpose of this project was to investigate how well each member agency's standards complied with the Councils on Chiropractic Education International (CCEI) framework standards. Methods: Each of the CCEI member agencies were provided with a mapping template that was approved by all representatives. A representative from each agency independently mapped their agency's standards to the CCEI framework standards using the template document. Discrepancies were explored and discussed among members. Member agencies discussed with their constituents the omissions and areas that did not comply or adequately match the CCEI document. Changes or additions to member agency standards were made, and updated versions of the mapping were agreed by all CCEI representatives. Results: There were 12 sections containing 30 standards within the CCEI framework standards. The Council of Chiropractic Education Australasia and Council on Chiropractic Education Canada reported relevant standards for all 30 CCEI standards. The European Council on Chiropractic Education had 29 of 30 relevant standards, with no direct standard for service. The products that were created were an executive summary of our findings and a detailed map showing similarities for each of the member agencies. Conclusion: This mapping project demonstrated the similarities of the CCEI member agency standards and that these standards focused on outcomes-based chiropractic education. This quality improvement project resulted in useful dialogue among the member agencies during this project, which clarified areas of difference.

Factors Associated With Pain Medication Use and the Relationship to Chiropractic Treatment Outcomes for Patients With Low Back and Neck Pain: A Cross-Sectional Study.

OBJECTIVE: The study objectives were to identify baseline factors associated with pain medication use and determine any differences in chiropractic treatment outcomes in patients with low back pain (LBP) and neck pain (NP) depending on their use of pain medication. METHODS: This cross-sectional, prospective outcomes study included 1077 adults with acute or chronic LBP and 845 adults with acute or chronic NP recruited from Swiss chiropractors in their offices within 4 years. Demographic data and the responses to the Patient's Global Impression of Change scale collected at 1 week, 1 month, 3 months, 6 months, and 1 year were analyzed with the χ2 test. Baseline pain and disability levels were measured using the numeric rating scale (NRS), Oswestry questionnaire for LBP, and Bournemouth questionnaire for patients with NP and analyzed with the Mann-Whitney U test between the 2 groups. To detect significant predictors of medication use at baseline, logistic regression analysis was performed. RESULTS: Patients with acute LBP and NP were more likely than those with chronic pain to take pain medication (P < .001 LBP; P = .003 NP). Medication use was more likely with patients with radiculopathy (P < .001 LBP; P = .05 NP) who were smokers (P = .008 LBP; P = .024 NP) and those reporting below-average general health (P < .001 LBP and NP). Pain medication users had higher baseline pain (P < .001 LBP and NP) and disability (P < .001 LBP and NP) scores. CONCLUSION: Patients with LBP and NP had significantly higher pain and disability levels at baseline, tended to have radiculopathy and poor health, were smokers, and presented during the acute phase. However, for this sample of patients, there were no differences in subjective improvement between users and non-users of pain medication for any data collection time point, which has management implications.

Chiropractic program changes facilitated by the European Council on Chiropractic Education Accreditation reports.

OBJECTIVE: The European Council on Chiropractic Education (ECCE) currently accredits 10 programs throughout Europe and South Africa. It is assumed that ECCE evaluation activities lead to changes to the chiropractic programs but no systematic evaluation as to whether this is true, and the extent of changes has previously been done. The purpose of this study was to obtain feedback from program heads as to whether ECCE evaluation reports facilitated changes/improvements to their programs and to identify their reported changes. METHODS: This was a mixed methods audit study using questionnaires with 2 sections. Closed statements requesting the degree of change to each section of the "Standards" based on ECCE evaluation reports (substantial, some, none) were analyzed using frequencies. Written responses identifying the specific changes made based on previous evaluation reports were evaluated independently by 3 researchers using a modified "thematic analysis" approach. RESULTS: All 10 accredited programs responded. Seven of the 10 programs (70%) reported "some" or "substantial" changes to ≥ 6 sections of the ECCE Standards. The most common section with reported changes was "Educational Program" (8 of 10). "Educational Resources" had the largest number of programs reporting "substantial changes" (4) and was the second most common section to have reported changes. The main themes identified emphasized changes in "infrastructure, equipment and faculty," "increasing evidence-based practice," and "instilling a research culture in faculty and students." CONCLUSION: ECCE accreditation processes facilitate changes to the chiropractic programs, particularly in the areas of improved infrastructure and faculty, research, and evidence-based practice.

Hip MRI findings and outcomes following imaging-guided hip injections.

OBJECTIVE: To determine if MRI findings prior to intra-articular corticosteroid hip infiltration are related to treatment outcomes. METHODS: This prospective outcome study with retrospective MRI evaluation includes 100 consecutive patients with MRI within 6 months before a therapeutic intra-articular hip injection. Labrum, bone marrow, acetabular and femoral cartilage abnormalities were assessed by two radiologists blinded to patient outcomes: the proportion reporting "improvement" on the Patient's Global Impression of Change (PGIC) scale at 1 day, 1 week and 1 month follow-up were compared based on MRI findings using χ2. The t-test was used to compare pain change scores with MRI abnormalities. RESULTS: Patients with a normal labrum in the posterosuperior quadrant were more likely to report PGIC "improvement" at 1 week compared to labral degeneration (p = 0.048). Significant differences in pain change scores were found at all time points for the labral anteroinferior quadrant (p = 0.001, 1 day; p = 0.010, 1 week; p = 0.034, 1 month) with the highest reduction in patients with labral degeneration. Females were 2.80 times more likely to report clinically relevant "improvement" at 1 day (p = .049) and 2.90 times more likely to report clinically relevant "improvement" at 1 month (p = .045). CONCLUSION: Cartilage defects and marrow abnormalities were not associated with outcomes. Patients with a normal labrum in the posterosuperior quadrant had better outcomes at 1 week. Patients with labral degeneration of the anteroinferior quadrant had higher levels of pain reduction at all time points. Females were significantly more likely to report PGIC "improvement". ADVANCES IN KNOWLEDGE: A significant treatment outcome was observed amongst gender, although there were no significant differences in the MRI findings.

Value of MR arthrography findings for pain relief after glenohumeral corticosteroid injections in the short term.

OBJECTIVES: This study was conducted in order to determine the predictive value of MR arthrography findings for pain relief after glenohumeral corticosteroid injection. METHODS: This study prospectively enrolled 212 patients (mean age 51.4 years; range 15-90) who underwent fluoroscopy-guided glenohumeral corticosteroid injection. All patients received MR arthrography of the shoulder less than 3 months prior to the infiltration and returned questionnaires which assessed patients' shoulder pain using the 11-point numeric rating scale (NRS), covering a 1-month follow-up period. MR arthrograms were retrospectively assessed for abnormalities of the rotator cuff, long biceps tendon, glenohumeral bone, cartilage, and labrum as well as for synovitis, bursitis, and signs of adhesive capsulitis. MR arthrography findings were compared to patients' NRS change using the Mann-Whitney U and Kruskal-Wallis tests for univariate analysis and multiple linear regression for multivariate analysis. RESULTS: Pain reduction of ≥ 2 points was considered to represent clinically relevant improvement, which was seen in 71% of patients 1 week and in 74% of patients 1 month after glenohumeral injection. Univariate analysis of MR findings showed that signs of adhesive capsulitis and an intact labrum were associated with significantly higher NRS reductions after 1 month in comparison to patients without these findings (median 4 vs. 3, p = 0.007 and 4 vs. 2, p = 0.003, respectively). Multivariate analysis proved both factors to be independent predictors of improved outcome after 1 month (beta = 0.176, p = 0.039 and beta = 0.212, p = 0.001, respectively). CONCLUSIONS: Glenohumeral corticosteroid injections for pain relief have a high success rate with 74% of patients reporting clinically relevant improvement after 1 month. Signs of adhesive capsulitis and an intact labrum on MR arthrography are independent predictors of a better outcome. KEY POINTS: • Seventy-four percent of patients report clinically relevant improvement 1 month after glenohumeral corticosteroid injection. • Signs of adhesive capsulitis and an intact labrum on MR arthrography are independent predictors of a high pain level decrease.

The European Council on Chiropractic Education identification of critical standards to accredit chiropractic programs: a qualitative study and thematic analysis.

OBJECTIVE: The objectives for this project were to: (1) identify and agree upon "critical standards" that must be "fully" or "substantially compliant" for a maximum 8-year reaccreditation, (2) compare recent compliance for each critical standard for all accredited programs, and (3) identify which standards have lower compliance levels compared to others. METHODS: This qualitative study uses thematic analysis. The 37 European Council on Chiropractic Education (ECCE) standards were assessed by the Quality Assurance Committee (QAC) to identify "critical standards" requiring "fully" or "substantially compliant" ratings for the maximum 8-year accreditation time period. These were approved by the entire ECCE. A table identifying specific criteria for each compliance level then was created. The most recent evaluation reports for all accredited programs were reviewed to record compliance levels for each critical standard and identify the number falling below the status of "substantially compliant". Specific standards with the highest proportion falling below "substantially compliant" also were identified. RESULTS: Eighteen of 37 standards were deemed critical. Two of 10 accredited programs had 0 "critical standards" below "substantially compliant" and two programs had three below this level. The most common standard to fall below "substantially compliant" was "faculty recruitment" with three programs (30%) at "partially compliant." CONCLUSION: Identification and approval of "critical standards" requiring at least substantial compliance and the compliance criteria table facilitate implementation of the flexible 8-year reaccreditation period, providing the flexibility needed to work collaboratively with national accrediting agencies. "Faculty recruitment" standard had the highest percentage of programs rated as "partially" compliant.

Fluoroscopy-guided versus CT-guided Lumbar Steroid Injections: Comparison of Radiation Exposure and Outcomes.

Purpose To compare the radiation exposure for participants and interventionalists as well as participant outcomes between fluoroscopy-guided versus CT-guided lumbar spinal injections. Materials and Methods This prospective, nonrandomized observational study included 1446 participants (mean age, 60.6 years; range, 18-91 years) who received transforaminal epidural injections or facet joint injections under fluoroscopic or CT guidance between October 2009 and April 2016. Effective doses were estimated by conversion from dose-area product for fluoroscopy-guided injections and dose-length product for CT-guided injections. Radiation exposure for interventionalists was measured with dosimeters at the body and wrist. The Patient Global Impression of Change (PGIC) scale was used to assess clinical participant outcomes at 1 day, 1 week, and 1 month after lumbar spine injections. Student t and χ2 tests were used for statistical analysis. Results The mean effective participant dose for fluoroscopy-guided lumbar transforaminal epidural injections was 0.24 mSv ± 0.22, compared with 0.33 mSv ± 0.10 for CT-guided injections (P < .003). The mean effective participant dose for fluoroscopy-guided lumbar facet joint injections was 0.10 mSv ± 0.11, compared with 0.33 mSv ± 0.13 for CT-guided injections (P < .001). Radiation exposure for the interventionalist was higher during fluoroscopy-guided compared with CT-guided lumbar transforaminal epidural injections (body: 0.42 × 10-3 mSv ± 0.99 vs 0.11 × 10-3 mSv ± 0.44, P < .03; wrist: 1.44 × 10-3 mSv ± 2.69 vs 0.14 × 10-3 mSv ± 0.55, P < .001). Radiation exposure of the wrist for the interventionalist was higher during fluoroscopy-guided compared with CT-guided lumbar facet injections (0.46 × 10-3 mSv ± 0.93 vs 0.06 × 10-3 mSv ± 0.24, respectively; P < .006). Clinical participant outcomes as determined with the PGIC scale did not differ between fluoroscopy-guided and CT-guided injections (P = .15-.96). Conclusion Radiation exposure in fluoroscopy-guided lumbar spinal injections was lower for participants and higher for physicians when compared with CT-guided injections; however, no associations were observed between clinical participant outcomes and type of imaging-guided injection technique at all evaluated time points. © RSNA, 2019.

Particulate versus non-particulate corticosteroids for transforaminal nerve root blocks: Comparison of outcomes in 494 patients with lumbar radiculopathy.

PURPOSE: We set out to compare outcomes in CT-guided lumbar transforaminal nerve root block patients receiving either particulate or non-particulate corticosteroids. MATERIALS AND METHODS: This was a retrospective comparative effectiveness outcomes study on two cohorts of lumbar radiculopathy patients. 321 received particulate and 173 non-particulate corticosteroids at CT-guided transforaminal lumbar nerve root injections. The particulate steroid was used from October 2009 until May 2014 and the non-particulate steroid was used from May 2014. Pain levels were collected at baseline using an 11-point numerical rating scale (NRS) and at 1 day, 1 week and 1 month. Overall 'improvement' was assessed using the Patients' Global Impression of Change (PGIC) at these same time points (primary outcome). The proportions of patients 'improved' were compared between the two groups using the Chi-square test. The NRS change scores were compared using the unpaired t-test. RESULTS: A significantly higher proportion of patients treated with particulate steroids were improved at 1 week (43.2 % vs. 27.7 %, p = 0.001) and at 1 month (44.3 % vs. 33.1 %, p = 0.019). Patients receiving particulate steroids also had significantly higher NRS change scores at 1 week (p = 0.02) and 1 month (p = 0.007). CONCLUSION: Particulate corticosteroids have significantly better outcomes than non-particulate corticosteroids. KEY POINTS: • Better pain relief is achieved with particulate steroids. • Significantly more patients report overall 'improvement' with particulate steroids. • Significantly more patients report 'worsening' at 1 week with non-particulate steroids.

Exploring the definition of «acute¼ neck pain: a prospective cohort observational study comparing the outcomes of chiropractic patients with 0-2 weeks, 2-4 weeks and 4-12 weeks of symptoms.

BACKGROUND: Neck pain is a common complaint in chiropractic patients. Amongst other baseline variables, numerous studies identify duration of symptoms as a strong predictor of outcome in neck pain patients. The usual time frame used for 'acute' onset of pain is between 0 and 4 weeks. However, the appropriateness of this time frame has been challenged for chiropractic low back pain patients. Therefore, the purpose of this study was to compare outcomes in neck pain patients with 0-2 vs 2-4 and 4-12 weeks of symptoms undergoing chiropractic treatment. METHODS: This is a prospective cohort observational study with 1 year follow-up including 495 patients whose data was collected between October 2009 and March 2015. Patients were divided into high-acute (0-2 weeks), mid-acute (2-4 weeks) and subacute (4-12 weeks) corresponding to duration of their symptoms at initial treatment. Patients completed the numerical pain rating scale (NRS) and Bournemouth questionnaire for neck pain (BQN) at baseline. At follow-up time points of 1 week, 1 month, 3 months, 6 months and 1 year the NRS and BQN were completed along with the Patient Global Impression of Change (PGIC) scale. The PGIC responses were dichotomized into 'improved' and 'not improved' patients and compared between the 3 subgroups. The Chi-square test was used to compare improved patients between the 3 subgroups and the unpaired Student's t-test was used for the NRS and BQN change scores. RESULTS: The proportion of patients 'improved' was only significantly higher for patients with symptoms of 0-2 weeks compared to 2-4 weeks at the 1 week outcome time point (p = 0.015). The NRS changes scores were significantly greater for patients with 2-4 weeks of symptoms compared to 4-12 weeks of symptoms only at 1 week (p = 0.035). CONCLUSIONS: The time period of 0-4 weeks of symptoms as the definition of "acute" neck pain should be maintained. Independent of the exact duration of symptoms, medium-term and long-term outcome is favourable for acute as well as subacute neck pain patients. TRIAL REGISTRATION: Not applicable for prospective cohort studies. Ethics approval prior to study EK 19/2009.

Comparison of treatment outcomes in neck pain patients depending on the sex of the chiropractor: a prospective outcome study.

BACKGROUND: The high percentage of female chiropractic students in Switzerland suggests a future sex shift in the chiropractic profession in Switzerland. Thus the purpose of this study is to determine if male and female chiropractors achieve the same treatment outcomes in neck pain patients. METHODS: Included in this prospective outcomes study were 849 patients with neck pain of any duration. Prior to the first treatment, baseline demographic data, the Bournemouth Questionnaire (BQ) and the numerical rating scale (NRS) for neck and arm pain were completed. At the follow-up time points of 1 week, 1, 3, 6 and 12 months, the Patient's Global Impression of Change (PGIC) scale to categorize the actual 'improvement' and the BQ and the NRS for neck pain were completed. The Chi-square test compared the proportion of patients reporting 'improvement' between male and female chiropractors for each time point. The unpaired Student's t-test compared the BQ and the NRS actual and change scores between patients of male and female chiropractors at all time points. Demographic factors were compared between the sexes using the Chi-square test. RESULTS: Proportionally more patients of female chiropractors reported 'improvement' at 1 month (p = 0.035) and significantly more pain reduction at 3 months (p = 0.040). Patients of male chiropractors presented with significant older age (p = 0.0001), higher levels of baseline neck pain (p = 0.012), a lower proportion with radiculopathy (p = 0.014) and less pain medication use (p = 0.046). CONCLUSIONS: Female chiropractors achieve at least equally satisfying treatment results for neck pain patients compared to male chiropractors. Female chiropractors also have a higher proportion of female patients compared to male chiropractors and patients presenting with radiculopathy and using pain medications. TRIAL REGISTRATION: Not applicable for this type of study.

Differences in Outcomes of Patients Treated by Male vs Female Chiropractors.

OBJECTIVE: The purpose of this study was to compare treatment outcomes of low back pain patients depending on the sex of the treating doctor of chiropractic (DC). METHODS: For this study, 1095 adult patients with no manual therapy in the prior 3 months were recruited. Pretreatment pain levels (Numeric Rating Scale for pain [NRS]), Oswestry Disability Index (ODI), and patient demographic details were recorded. The NRS and Patient Global Impression of Change were assessed after 1 week and 1, 3, 6, and 12 months. The ODI was completed up to 3 months. The χ2 test compared sex of the DC with the proportion of patients "improved" at all time points and with baseline categorical variables. The unpaired t test compared changes in NRS and ODI scores between patients of male and female DCs. RESULTS: Female DCs saw proportionally more acute patients (P = .012). Patients of male DCs presented more often with radiculopathy (P = .007). There were no differences in NRS and ODI baseline scores between male and female DCs' patients. At 1 week and 3 and 12 months, significantly more patients of female DCs reported improvement and they had greater decreases in NRS and ODI scores at 1 week. Removing acute patients from the data, there were no longer differences in outcome. CONCLUSIONS: Significant differences in treatment outcome in favor of female DCs was no longer present on removal of the acute subgroup from the data. This suggests that patient outcome is influenced by other factors, such as chronicity, rather than sex of the treating DC.

Differences in Practice Characteristics Between Male and Female Chiropractors in Switzerland.

OBJECTIVES: A total of 75% of the chiropractic medicine students in the new program at the University of Zürich are women, which is in stark contrast to the traditional ratio of chiropractors in Switzerland, where 75% have been men. Therefore, the purpose of this study was to compare work behaviors between female and male chiropractors relating to workload, patient variety, and chiropractic treatment techniques. METHODS: This is a secondary analysis of data from the Swiss Job Analysis 2009 study. The design was an online survey to all practicing chiropractors in Switzerland that had a 70% response rate of 183 returned surveys. Differences between male and female chiropractors in the various categorical responses involving practice workload, characteristics and patient types were compared using the χ2 test. RESULTS: Male chiropractors had significantly more years in practice (P = .0001), worked more hours per week (P = .0001), and saw more patients (P = .0001) and more new patients (P = .004) per week compared with female chiropractors. Female chiropractors spent significantly more time with patients during follow-up visits (P = .017). There were no significant differences in treatment techniques used or the types of patients seen between the sexes. CONCLUSION: Because female chiropractors work fewer hours and see fewer patients per week, this may lead to a shortage of chiropractors in the future as the sex ratio within the profession slowly changes in Switzerland.

Comparison of Chiropractic Treatment Outcomes Depending on the Language Region in Switzerland: A Prospective Outcomes Study.

OBJECTIVES: Switzerland has optimal conditions for research of language-based cultural influences on low back pain (LBP). The aim of this study was to compare LBP treatment outcomes after chiropractic care between patients from the German- and French-speaking regions of Switzerland. METHODS: Baseline Numeric Rating Scale for pain (NRS), demographic, and Oswestry Disability Index (ODI) data were collected from patients presenting to 51 Swiss-German and 12 Swiss-French chiropractors. Prospective outcome data included the proportion reporting clinically relevant improvement on the Patient Global Impression of Change scale and the NRS change scores collected at 1 week; 1, 3, and 6 months; and 1 year. ODI change scores were collected until 3 months. The proportion improved between the 2 groups was compared using the χ2 test. NRS and ODI change scores were compared using the unpaired t test. RESULTS: At baseline, only patient age comparing 853 Swiss-German and 215 Swiss-French patients revealed a significant difference. The Patient Global Impression of Change, NRS, and ODI had no significant differences between both patient groups up to 6 months. Between 6 months and 1 year the proportion reporting improvement continued to increase to 83.5% for German-speaking Swiss but reduced to 73.1% for French-speaking Swiss (P = .01). The NRS change scores were also higher for German speaking Swiss at 1 year compared with Swiss-French citizens (P = .01). CONCLUSION: Treatment outcome data for LBP are comparable in the German and French parts of Switzerland until the 1-year time point, when people located in the French-speaking regions are more likely to have an increase in pain levels.

Is there a difference in treatment outcomes between epidural injections with particulate versus non-particulate steroids?

OBJECTIVES: To compare the outcomes of patients after interlaminar computed tomography (CT)-guided epidural injections of the lumbar spine with particulate vs. non-particulate steroids. METHODS: 531 consecutive patients were treated with CT-guided lumbar interlaminar epidural injections with steroids and local anaesthetics. 411 patients received a particulate steroid and 120 patients received a non-particulate steroid. Pain levels were assessed using the 11-point numerical rating scale (NRS) and overall reported 'improvement' was assessed using the Patients Global Impression of Change (PGIC) at 1 day, 1 week and 1 month post-injection. Descriptive and inferential statistics were applied. RESULTS: Patients receiving particulate steroids had statistically significantly higher NRS change scores (p = 0.0001 at 1 week; p = 0.0001 at 1 month). A significantly higher proportion of patients receiving particulate steroids reported relevant improvement (PGIC) at both 1 week and 1 month post injection (p = 0.0001) and they were significantly less likely to report worsening at 1 week (p = 0.0001) and 1 month (p = 0.017). CONCLUSION: Patients treated with particulate steroids had significantly greater pain relief and were much more likely to report clinically relevant overall 'improvement' at 1 week and 1 month compared to the patients treated with non-particulate steroids. KEY POINTS: • CT-guided epidural injections of the lumbar spine with particulate vs. non-particulate steroids. • Good outcomes with particulate steroids. • Less pain relief in patients with non-particulate steroids. • Less improvement in patients with non-particulate steroids.

The Swiss Master in Chiropractic Medicine Curriculum: Preparing Graduates to Work Together With Medicine to Improve Patient Care.

OBJECTIVE: In 2007, chiropractic became 1 of the 5 medical professions in Switzerland. This required a new chiropractic program that was fully integrated within a Swiss medical school. The purpose of this article was to discuss the Master in Chiropractic Medicine (MChiroMed) program at the University of Zürich, including advantages, opportunities, and challenges. DISCUSSION: In 2008, the MChiroMed program began with its first student cohort. The MChiroMed program is a 6-year Bologna model 2-cycle (bachelor and master) "spiral curriculum," with the first 4 years being fully integrated within the medical curriculum. A review of the main features of the curriculum revealed the advantages, opportunities, and challenges of this program in comparison with other contemporary chiropractic educational programs. Advantages and opportunities include an integrated curriculum within a university, medical school, and musculoskeletal hospital, with their associated human and physical resources. Many opportunities exist for high-level research collaborations. The rigorous entrance qualifications and small student cohorts result in bright, motivated, and enthusiastic students; appropriate assessments; and timely feedback on academic and clinical subjects. Early patient contact in hospitals and clinical facilities encourages the integration of academic theory and clinical practice. The main challenges faced by this program include difficulty recruiting a sufficient number of students because of the rigorous entrance requirements and curriculum overload resulting from undertaking a full medical curriculum and chiropractic modules. CONCLUSIONS: The MChiroMed program is a unique chiropractic curriculum that integrates medical and chiropractic education within a spiral curriculum at a world-class Swiss university medical school. The expectation is that graduates, with their expanded diagnostic and therapeutic knowledge, skills, and experience, will become future experts in primary spine care in Switzerland. It is hoped that this curriculum model will be adopted by other countries and jurisdictions seeking to enhance the role of chiropractic in health care.

Relationship of Modic Changes, Disk Herniation Morphology, and Axial Location to Outcomes in Symptomatic Cervical Disk Herniation Patients Treated With High-Velocity, Low-Amplitude Spinal Manipulation: A Prospective Study.

OBJECTIVE: The purpose of this study was to evaluate whether cervical disk herniation (CDH) location, morphology, or Modic changes (MCs) are related to treatment outcomes. METHODS: Magnetic resonance imaging (MRI) and outcome data from 44 patients with CDH treated with spinal manipulative therapy were evaluated. MRI scans were assessed for CDH axial location, morphology, and MCs. Pain (0-10 for neck and arm) and Neck Disability Index (NDI) data were collected at baseline; 2 weeks; 1, 3, and 6 months; and 1 year. The Patient's Global Impression of Change data were collected at all time points and dichotomized into "improved," yes or no. Fischer's exact test compared the proportion improved with MRI abnormalities. Numerical rating scale and NDI scores were compared with MRI abnormalities at baseline and change scores at all time points using the t test or Mann-Whitney U test. RESULTS: Patients who were Modic positive had higher baseline NDI scores (P = .02); 77.8% of patients who were Modic positive and 53.3% of patients who were Modic negative reported improvement at 2 weeks (P = .21). Fifty percent of Modic I and 83.3% of Modic II patients were improved at 2 weeks (P = .07). At 3 months and 1 year, all patients with MCs were improved. Patients who were Modic positive had higher NRS and NDI change scores. Patients with central herniations were more likely to improve only at the 2-week time point (P = .022). CONCLUSIONS: Although patients who were Modic positive had higher baseline NDI scores, the proportion of these patients improved was higher for all time points up to 6 months. Patients with Modic I changes did worse than patients with Modic II changes at only 2 weeks.

Relationship of specific MRI findings to treatment outcomes in patients receiving transforaminal epidural steroid injections.

OBJECTIVES: To determine whether specific MRI findings are related to outcomes after lumbar transforaminal epidural steroid injections (TFESI) and to assess the inter-rater reliability of imaging diagnosis. MATERIALS AND METHODS: A prospective outcomes study on 156 consecutive patients with 1-month follow-up outcomes data and MRI within 3 months of TFESI was conducted. Pain levels (numerical rating scale) (NRS) were recorded prior to injection. Overall 'improvement' was determined using the Patients Global Impression of Change (PGIC) scale and NRS data were collected at three time points post injection. Two radiologists independently evaluated all images blinded to treatment outcome for reliability of diagnosis. The Chi-square test compared MRI findings for the senior radiologist to 'improvement'. NRS change scores were compared to MRI findings with the unpaired t-test or ANOVA. Kappa and percent agreement assessed inter-rater agreement of diagnosis. RESULTS: The only abnormality linked to 'improvement' (p = 0.03) and higher NRS change scores (p = 0.0001) at 1 month was the disc herniation morphology 'protrusion + sequestration'. Patients with degeneration by osteophytes (p = 0.034), grade 3 foraminal nerve root compression (p = 0.01) and foraminal/extraforaminal location of herniation (p = 0.014) also had higher 1 month NRS change scores. Reliability of diagnosis was 'fair' to 'substantial' depending on MRI findings. CONCLUSIONS: Patients with disc protrusion plus sequestration were significantly more likely to report overall improvement and more pain reduction at 1 month. Higher pain reduction was noted in patients with degeneration by osteophytes, grade 3 foraminal nerve root compression, or foraminal/extraforaminal disc herniation location.
