An advanced clinician practitioner in arthritis care can improve access to rheumatology care in community-based practice.

OBJECTIVE: To facilitate access and improve wait times to a rheumatologist's consultation, this study aimed to 1) determine the ability of an advanced clinician practitioner in arthritis care (ACPAC)-trained extended role practitioner (ERP) to triage patients with suspected inflammatory arthritis (IA) for priority assessment by a rheumatologist and 2) determine the impact of an ERP on access-to-care as measured by time-to-rheumatologist-assessment and time-to-treatment-decision. MATERIALS AND METHODS: A community-based ACPAC-trained ERP triaged new referrals for suspected IA. Patients with suspected IA were booked to see the rheumatologist on a priority basis. Diagnostic accuracy of the ERP to correctly identify priority patients; the level of agreement between ERP and rheumatologist (Kappa coefficient and percent agreement); and the time-to-treatment-decision for confirmed cases of IA were investigated. Retrospective chart review then compared time-to-rheumatologist-assessment and time-to-treatment-decision in the solo-rheumatologist versus the ERP-triage model. RESULTS: One hundred twenty-one patients were triaged. The ERP designated 54 patients for priority assessment. The rheumatologist confirmed IA in 49/54 (90.7% positive predictive value [PPV]). Of the 121 patients, 67 patients were designated as nonpriority by the ERP, and none were determined to have IA by the rheumatologist (100% negative predictive value [NPV]). Excellent agreement was found between the ERP and the rheumatologist (Kappa coefficient 0.92, 95% CI: 0.84-0.99). In the ERP-triage model, time-from-referral-to-treatment-decision for patients with IA was 73.7 days (SD 40.4, range 12-183) compared with 124.6 days (SD 61.7, range 26-359) in the solo-rheumatologist model (40% reduction in time-to-treatment-decision). CONCLUSION: A well-trained and experienced ERP can shorten the time-to-Rheumatologist-assessment and time-to-treatment-decision for patients with suspected IA.

Telemedicine delivery of patient education in remote Ontario communities: feasibility of an Advanced Clinician Practitioner in Arthritis Care (ACPAC)-led inflammatory arthritis education program.

OBJECTIVE: Telemedicine-based approaches to health care service delivery improve access to care. It was recognized that adults with inflammatory arthritis (IA) living in remote areas had limited access to patient education and could benefit from the 1-day Prescription for Education (RxEd) program. The program was delivered by extended role practitioners with advanced training in arthritis care. Normally offered at one urban center, RxEd was adapted for videoconference delivery through two educator development workshops that addressed telemedicine and adult education best practices. This study explores the feasibility of and participant satisfaction with telemedicine delivery of the RxEd program in remote communities. MATERIALS AND METHODS: Participants included adults with IA attending the RxEd program at one of six rural sites. They completed post-course program evaluations and follow-up interviews. Educators provided post-course feedback to identify program improvements that were later implemented. RESULTS: In total, 123 people (36 in-person and 87 remote, across 6 sites) participated, attending one of three RxEd sessions. Remote participants were satisfied with the quality of the video-conference (% agree/strongly agree): could hear the presenter (92.9%) and discussion between sites (82.4%); could see who was speaking at other remote sites (85.7%); could see the slides (95.3%); and interaction between sites adequately facilitated (94.0%). Educator and participant feedback were consistent. Suggested improvements included: use of two screens (speaker and slides); frontal camera angles; equal interaction with remote sites; and slide modifications to improve the readability on screen. Interview data included similar constructive feedback but highlighted the educational and social benefits of the program, which participants noted would have been inaccessible if not offered via telemedicine. CONCLUSION: Study findings confirm the feasibility of delivering the RxEd program to remote communities by using telemedicine. Future research with a focus on the sustainability of this and other models of technology-supported patient education for adults with IA across Ontario is warranted.

A prospective comparison of telemedicine versus in-person delivery of an interprofessional education program for adults with inflammatory arthritis.

Introduction We evaluated two modes of delivery of an inflammatory arthritis education program ("Prescription for Education" (RxEd)) in improving arthritis self-efficacy and other secondary outcomes. Methods We used a non-randomized, pre-post design to compare videoconferencing (R, remote using telemedicine) versus local (I, in-person) delivery of the program. Data were collected at baseline (T1), immediately following RxEd (T2), and at six months (T3). Self-report questionnaires served as the data collection tool. Measures included demographics, disorder-related, Arthritis Self-Efficacy Scale (SE), previous knowledge (Arthritis Community Research and Evaluation Unit (ACREU) rheumatoid arthritis knowledge questionnaire), coping efficacy, Illness Intrusiveness, and Effective Consumer Scale. Analysis included: baseline comparisons and longitudinal trends (R vs I groups); direct between-group comparisons; and Generalized Estimating Equations (GEE) analysis. Results A total of 123 persons attended the program (I: n = 36; R: n = 87) and 111 completed the baseline questionnaire (T1), with follow-up completed by 95% ( n = 117) at T2 and 62% ( n = 76) at T3. No significant baseline differences were found across patient characteristics and outcome measures. Both groups (R and I) showed immediate effect (improved arthritis SE, mean change (95% confidence interval (CI)): R 1.07 (0.67, 1.48); I 1.48 (0.74, 2.23)) after the program that diminished over six months (mean change (95% CI): R 0.45 (-0.1, 0.1); I 0.73 (-0.25, 1.7)). For each of the secondary outcomes, both groups showed similar trends for improvement (mean change scores (95% CI)) over time. GEE analysis did not show any meaningful differences between groups (R vs I) over time. Discussion Improvements in arthritis self-efficacy and secondary outcomes displayed similar trends for I and R participant groups.

A user's survey of the clinical application and content validity of the DASH (Disabilities of the Arm, Shoulder and Hand) outcome measure.

STUDY DESIGN: Survey. PURPOSE OF THE STUDY: To elicit feedback on the clinical use and content validity of the Disabilities of the Arm, Shoulder and Hand (DASH) outcome measure from frontline users of the instrument. METHODS: A cross-sectional survey was administered to registered DASH users and inquired about how the DASH was being used and to identify the informational value of items of the DASH (content validity). RESULTS: About 172 completed the survey. One or both of the DASH and/or QuickDASH were consistently (89.5%) being used. About 90% were using it in adults (21-65 years), and at least 70% were using it across the entire extremity, and to a lesser extent, 10% reported using it in isolated neck injuries. Most respondents (66.9%-75.8%) were using the DASH in musculoskeletal (MSK) disorders, with some applying it for other more unique or non-MSK conditions (2.5%-16.6%). All but 1 of the 30 DASH items had at least 10% endorsement as being informative, and 4 items were identified as being problematic by greater than 20%. CONCLUSIONS: The DASH is being used as intended (whole extremity and MSK conditions), and in addition, it is being used in different body regions and diverse conditions. LEVEL OF EVIDENCE: Not applicable (descriptive survey).

The patient perspective: arthritis care provided by Advanced Clinician Practitioner in Arthritis Care program-trained clinicians.

OBJECTIVE: To assess patient satisfaction with the arthritis care services provided by graduates of the Advanced Clinician Practitioner in Arthritis Care (ACPAC) program. MATERIALS AND METHODS: This was a cross-sectional evaluation using a self-report questionnaire for data collection. Participants completed the Patient-Doctor Interaction Scale, modified to capture patient-practitioner interactions. Participants completed selected items from the Group Health Association of America's Consumer Satisfaction Survey, and items capturing quality of care, appropriateness of wait times, and a comparison of extended-role practitioner (ERP) services with previously received arthritis care. RESULTS: A total of 325 patients seen by 27 ERPs from 15 institutions completed the questionnaire. Respondents were primarily adults (85%), female (72%), and living in urban areas (79%). The mean age of participants was 54 years (range 3-92 years), and 51% were not working. Patients with inflammatory (51%) and noninflammatory conditions (31%) were represented. Mean (standard deviation) Patient-Practitioner Interaction Scale subscale scores ranged from 4.50 (0.60) to 4.63 (0.48) (1 to 5 [greater satisfaction]). Overall satisfaction with the quality of care was high (4.39 [0.77]), as was satisfaction with wait times (referral to appointment, 4.27 [0.86]; in clinic, 4.24 [0.91]). Ninety-eight percent of respondents felt the arthritis care they received was comparable to or better than that previously received from other health care professionals. CONCLUSION: Patients were very satisfied with and amenable to arthritis care provided by graduates of the ACPAC program. Our findings provide early support for the deployment and integration of ACPAC ERPs into the Ontario health care system and should inform future evaluation at the patient level.

What interventions improve walking ability in neurogenic claudication with lumbar spinal stenosis? A systematic review.

PURPOSE: To investigate what interventions can improve walking ability in neurogenic claudication with lumbar spinal stenosis. METHODS: We searched CENTRAL, Medline, EMBASE, CINAHL and ICL databases up to June 2012. Only randomized controlled trials published in English and measuring walking ability were included. Data extraction, risk of bias assessment, and quality of the evidence evaluation were performed using methods of the Cochrane Back Review Group. RESULTS: We accepted 18 studies with 1,220 participants. There is very low quality evidence that calcitonin is no better than placebo or paracetamol regardless of mode of administration. There is low quality evidence that prostaglandins, and very low quality evidence that gabapentin or methylcobalamin, improves walking distance. There is low and very low quality evidence that physical therapy was no better in improving walking ability compared to no treatment, oral diclofenac plus home exercises, or combined manual therapy and exercise. There is very low quality evidence that epidural injections improve walking distance up to 2 weeks compared to placebo. There is low- and very low-quality evidence that various direct decompression surgical techniques show similar significant improvements in walking ability. There is low quality evidence that direct decompression is no better than non-operative treatment in improving walking ability. There is very low quality evidence that indirect decompression improves walking ability compared to non-operative treatment. CONCLUSIONS: Current evidence for surgical and non-surgical treatment to improve walking ability is of low and very low quality and thus prohibits recommendations to guide clinical practice.

Nonoperative treatment for lumbar spinal stenosis with neurogenic claudication.

BACKGROUND: Lumbar spinal stenosis with neurogenic claudication is one of the most commonly diagnosed and treated pathological spinal conditions. It frequently afflicts the elderly population. OBJECTIVES: To systematically review the evidence for the effectiveness of nonoperative treatment of lumbar spinal stenosis with neurogenic claudication. SEARCH METHODS: CENTRAL, MEDLINE, CINAHL, and Index to Chiropractic Literature (ICL) databases were searched up to June 2012. SELECTION CRITERIA: Randomized controlled trials published in English, in which at least one arm provided data on nonoperative treatments DATA COLLECTION AND ANALYSIS: We used the standard methodological procedures expected by The Cochrane Collaboration. Risk of bias in each study was independently assessed by two review authors using the 12 criteria recommended by the Cochrane Back Review Group (Furlan 2009). Dichotomous outcomes were expressed as relative risk, continuous outcomes as mean difference or standardized mean difference; uncertainty was expressed with 95% confidence intervals. If possible a meta-analysis was performed, otherwise results were described qualitatively. GRADE was used to assess the quality of the evidence. MAIN RESULTS: From the 8635 citations screened, 56 full-text articles were assessed and 21 trials (1851 participants) were included. There was very low-quality evidence from six trials that calcitonin is no better than placebo or paracetamol, regardless of mode of administration or outcome assessed. From single small trials, there was low-quality evidence for prostaglandins, and very low-quality evidence for gabapentin or methylcobalamin that they improved walking distance. There was very low-quality evidence from a single trial that epidural steroid injections improved pain, function, and quality of life, up to two weeks, compared with home exercise or inpatient physical therapy. There was low-quality evidence from a single trial that exercise is of short-term benefit for leg pain and function compared with no treatment. There was low and very low-quality evidence from six trials that multimodal nonoperative treatment is less effective than indirect or direct surgical decompression with or without fusion. A meta-analysis of two trials comparing direct decompression with or without fusion to multimodal nonoperative care found no significant difference in function at six months (mean difference (MD) -3.66, 95% CI -10.12 to 2.80) and one year (MD -6.18, 95% CI -15.03 to 2.66), but at 24 months a significant difference was found favouring decompression (MD -4.43, 95% CI -7.91 to -0.96). AUTHORS' CONCLUSIONS: Moderate and high-quality evidence for nonoperative treatment is lacking and thus prohibits recommendations for guiding clinical practice. Given the expected exponential rise in the prevalence of lumbar spinal stenosis with neurogenic claudication, large high-quality trials are urgently needed.

Measurement properties of the QuickDASH (disabilities of the arm, shoulder and hand) outcome measure and cross-cultural adaptations of the QuickDASH: a systematic review.

PURPOSE: To identify and synthesize evidence for the measurement properties of the QuickDASH, a shortened version of the 30-item DASH (Disabilities of the Arm, Shoulder and Hand) instrument. METHODS: This systematic review used a best evidence synthesis approach to critically appraise the measurement properties [using COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN)] of the QuickDASH and cross-cultural adaptations. A standard search strategy was conducted between 2005 (year of first publication of QuickDASH) and March 2011 in MEDLINE, EMBASE and CINAHL. RESULTS: The search identified 14 studies to include in the best evidence synthesis of the QuickDASH. A further 11 studies were identified on eight cross-cultural adaptation versions. CONCLUSIONS: Many measurement properties of the QuickDASH have been evaluated in multiple studies and across most of the measurement properties. The best evidence synthesis of the QuickDASH English version suggests that this tool is performing well with strong positive evidence for reliability and validity (hypothesis testing), and moderate positive evidence for structural validity testing. Strong negative evidence was found for responsiveness due to lower correlations with global estimates of change. Information about the measurement properties of the cross-cultural adaptation versions is still lacking, or the available information is of poor overall methodological quality.

Nonoperative treatment of lumbar spinal stenosis with neurogenic claudication: a systematic review.

STUDY DESIGN: Systematic review. OBJECTIVE: To systematically review the evidence for the effectiveness of nonoperative treatment of lumbar spinal stenosis with neurogenic claudication. SUMMARY OF BACKGROUND DATA: Neurogenic claudication can significantly impact functional ability, quality of life, and independence in the elderly. METHODS.: We searched CENTRAL, MEDLINE, EMBASE, CINAHL, and ICL databases up to January 2011 for randomized controlled trials published in English, in which at least 1 arm provided data on nonoperative treatments. Risk of bias in each study was independently assessed by 2 reviewers using 12 criteria. Quality of the evidence was evaluated using Grades of Recommendations, Assessment, Development, and Evaluation (GRADE). RESULTS: From the 8635 citations screened, 56 were assessed and 21 trials with 1851 participants were selected. There is very low-quality evidence from 6 trials that calcitonin is no better than placebo or paracetamol, regardless of mode of administration or outcome. From single small trials, there is low-quality evidence that prostaglandins, and very low-quality evidence that gabapentin or methylcobalamin, improve walking distance. There is very low-quality evidence from a single trial that epidural steroid injections improve pain, function, and quality of life up to 2 weeks compared with home exercise or inpatient physical therapy. There is low-quality evidence from a single trial that exercise is of short-term benefit for leg pain and function compared with no treatment. There is low- and very low-quality evidence from 6 trials that multimodal nonoperative treatment is less effective than indirect or direct surgical decompression with or without fusion. CONCLUSION: Moderate- and high-GRADE evidence for nonoperative treatment is lacking and thus prohibiting recommendations to guide clinical practice. Given the expected exponential rise in the prevalence of lumbar spinal stenosis with neurogenic claudication, large high-quality trials are urgently needed.

Prescription for education: development, evaluation, and implementation of a successful interprofessional education program for adults with inflammatory arthritis.

OBJECTIVE: To assess the feasibility of recruitment and standardize care delivery for an interprofessional program for inflammatory arthritis education (Prescription for Education, or RxEd), and to explore outcomes relevant to arthritis patient education. METHODS: A patient-based needs assessment and ongoing patient feedback guided program development. An interprofessional team was involved in developing program content and delivering and adapting the program to patient needs. A quasiexperimental, waitlisted control with crossover design was used to evaluate the program. Data were collected at baseline, immediately following intervention, at 6 months (when the crossover control group received intervention), and at 1 year. Self-report measures included demographics, disorder-related data, Arthritis Self-efficacy Scale, arthritis knowledge, coping efficacy, and illness intrusiveness. Analysis included baseline comparisons and longitudinal trends; direct between-group comparison at 6 months; and generalized estimating equations (GEE) analysis to evaluate the main effect of the intervention on the primary outcome (arthritis self-efficacy) and secondary outcomes. RESULTS: Program modifications based on patient input made recruitment possible. Forty-two persons participated (including 19 controls), with 93% followup at 1 year. Comparison of change shows moderate effect sizes (standardized effect size 0.5 to 0.7). GEE analysis showed significant main effect, before to after the program, in both groups for primary outcome (arthritis self-efficacy) and most secondary outcomes. CONCLUSION: Program feasibility was dependent on patient feedback. Our pilot study provides evidence that the RxEd program is feasible and improves arthritis self-efficacy and other outcomes.

Minimal change is sensitive, less specific to recovery: a diagnostic testing approach to interpretability.

OBJECTIVE: The pursuit of interpretability of longitudinal measures of patient outcome has led to several methods for defining minimal amounts of change or final states that are important. Little is known about the best method. The purpose of this study was to directly compare methods using diagnostic utility to evaluate their usefulness. STUDY DESIGN AND SETTING: Secondary analysis of longitudinal cohort data of persons attending physiotherapy for shoulder pain. Disability of the arm, shoulder, and hand outcome fielded at baseline and 3 months. Published methods were used to define positive response in scores: minimal change, final state, and combined change and final state. Proportions described as improved were compared (Kappa) and diagnostic testing techniques used to evaluate the strengths of each. RESULTS: Only moderate agreement was found between methods (Kappa=0.47). Minimal clinically important differences were most sensitive but not specific. Final states were less sensitive, more specific, and most accurate. Combinations were slightly less specific. CONCLUSION: A new approach allowed us to evaluate the relative merits and risks of different approaches to interpreting longitudinal patient outcomes. Our study points to a combination of change greater than error and/or a final score within general population norms as being the most clinically sensible with strong diagnostic accuracy.

Systematic review of the role of occupational health and safety interventions in the prevention of upper extremity musculoskeletal symptoms, signs, disorders, injuries, claims and lost time.

BACKGROUND: Little is known about the most effective occupational health and safety (OHS) interventions to reduce upper extremity musculoskeletal disorders (MSDs) and injuries. METHODS: A systematic review used a best evidence synthesis approach to address the question: "do occupational health and safety interventions have an effect on upper extremity musculoskeletal symptoms, signs, disorders, injuries, claims and lost time?" RESULTS: The search identified 36 studies of sufficient methodological quality to be included in data extraction and evidence synthesis. Overall, a mixed level of evidence was found for OHS interventions. Levels of evidence for interventions associated with positive effects were: Moderate evidence for arm supports; and Limited evidence for ergonomics training plus workstation adjustments, new chair and rest breaks. Levels of evidence for interventions associated with "no effect" were: Strong evidence for workstation adjustment alone; Moderate evidence for biofeedback training and job stress management training; and Limited evidence for cognitive behavioral training. No interventions were associated with "negative effects". CONCLUSION: It is difficult to make strong evidenced-based recommendations about what practitioners should do to prevent or manage upper extremity MSDs. There is a paucity of high quality OHS interventions evaluating upper extremity MSDs and none focused on traumatic injury outcomes or workplace mandated pre-placement screening exams. We recommend that worksites not engage in OHS activities that include only workstation adjustments. However, when combined with ergonomics training, there is limited evidence that workstation adjustments are beneficial. A practice to consider is using arm supports to reduce upper extremity MSDs.

Research to practice--formal dissemination of the School Health and Alcohol Harm Reduction Project (SHAHRP) in Australia.

INTRODUCTION AND AIMS: This paper discusses the formal dissemination of the School Health and Alcohol Harm Reduction Project (National SHAHRP Dissemination Project) in Australia. The original SHAHRP research programme (SHAHRP study) was assessed previously for effectiveness during a longitudinal research study which followed the student participants over 32 months post-intervention. The SHAHRP study focused on evaluating the behavioural impact of the programme and the results indicated that wider dissemination would be of value. DESIGN AND METHODS: The National SHAHRP Dissemination Project involved key decision makers of drug education in the Government, Catholic and Independent schools sectors, in targeted states, agreeing to disseminate the SHAHRP Project through teacher educators and teachers in their sector and regions. Process, reach and project satisfaction were assessed. RESULTS: The Dissemination Project conducted two workshops for 35 teacher educators. Fifteen teacher educators subsequently conducted 21 workshops for teachers between August 2003 and June 2004. One hundred and seventy schools and nearly 300 (294) teachers were involved in this training. DISCUSSION AND CONCLUSIONS: The advantages and barriers of researcher-led dissemination, as illustrated in this study, suggest that methods other than publication in scientific journals and presentation at conferences may be useful for the transfer of effective intervention research programmes to practice. There may be some benefit to identifying and testing other research-initiated pathways leading to evidence-based policy and practice which, in combination with practitioner-led transfer, can help to bridge the gap between research and practice in the future.

Prognosis in soft tissue disorders of the shoulder: predicting both change in disability and level of disability after treatment.

BACKGROUND AND PURPOSE: Clinicians often are faced with questions about prognosis and outcome of shoulder disorders. The purpose of this study was to identify predictors of both change in disability and level of disability following physical therapy treatment. SUBJECTS: The subjects were consecutive patients (n=361) who were receiving physical therapy for soft tissue shoulder disorders. METHODS: Clinical response to physical therapy, which was measured using the Disabilities of the Arm, Shoulder, and Hand (DASH) measure, was assessed over 12 weeks. The 28 independent baseline predictors included demographics, disorder-related and disability measures, medication use, clinical findings, and expectations for recovery. Multiple linear regression techniques were used. RESULTS: Predictors of greater disability at discharge were: higher initial disability, therapist prediction of restricted activities at discharge, workers' compensation claim, older age, and being female. Predictors of greater improvement in disability were: shoulder surgery, higher pain intensity, shorter duration of symptoms, younger age, and poorer general physical health (measured using the 36-Item Short-Form Health Survey [SF-36]). DISCUSSION AND CONCLUSIONS: Prognostic factors differ depending on the format of the outcome. Only age was significant in both models.

Eight predictive factors associated with response patterns during physiotherapy for soft tissue shoulder disorders were identified.

BACKGROUND AND OBJECTIVE: Combining information on initial and final state with information on speed of response may reflect the clinical reality of the course of recovery from soft tissue shoulder disorders. The purpose was to identify baseline factors that predict patterns of response to physiotherapy. STUDY DESIGN AND SETTING: Prospective cohort of consecutive clients (n=361) with soft tissue shoulder disorders attending physiotherapy. A previous study identified four typical patterns of response such that each individual was assigned to one of four clusters (dependent outcome). Independent predictors (n=28) included demographics, disorder-related and disability measures, treatment factors, clinical findings, and expectations for recovery. Multivariable multinomial logistic regression techniques were used. RESULTS: Predictors differentiating patterns of response were: Age (by decade), duration of current shoulder problem, worker's compensation claim, client's global rating of problem, Physical Component Score (SF-36), Mental Component Score (SF-36), over the counter medication use, and therapist prediction of client to return to usual activity. CONCLUSION: Using a clinically sensible outcome, we have identified several predictors that can be used by clinicians in clinical decision making.

Beyond return to work: testing a measure of at-work disability in workers with musculoskeletal pain.

BACKGROUND: There are a limited number of validated measures of a patient's perception of the level of difficulty that they are having at their job. The purpose of this study was to evaluate the psychometric properties of the 16-item Work Limitations Questionnaire (WLQ-16). METHODS: A sample of 42 workers reporting to a workplace occupational health unit with upper limb or low back pain were enrolled in an observational study. Participants were assessed at baseline, 4 and 12 weeks post reporting. Psychometric testing (distributions, Cronbach's alpha, construct validity and responsiveness to change in problem and pain) was done using the baseline and 12-week data. RESULTS: The WLQ-16 had evidence of internal consistency, construct validity and responsiveness. Some ceiling effect was found in the domains of mental-interpersonal and output demands. Physical demands suffered from missing values in 18/42 due to not-applicable content. Construct validity revealed that there was less discrimination at the higher (less limited) end of the scale. Responsiveness was present, though less than found with other measures of function and pain. CONCLUSIONS: The WLQ-16 shows promise as a measure of at-work disability. Further testing to evaluate the ceiling effect and responsiveness to constructs of change more closely related to work disability is recommended.
