RESUMO
BACKGROUND: Patients undergoing lumbar spine surgery have high rates of preoperative opioid use, which is associated with inferior outcomes and higher risks for opioid dependency postoperatively. PURPOSE: Determine whether there are identifiable subgroups of patients that follow distinct patterns in pre- and postoperative opioid dosing. Examine how preoperative patterns in opioid dosing relate to postoperative opioid patterns, opioid cessation, and the risk for adverse events. STUDY DESIGN/SETTING: Retrospective analysis of an administrative claims database (MeritiveTM Marketscan® Research Databases 2007-2015). PATIENT SAMPLE: The 9,768 patients undergoing primary single level lumbar fusion. OUTCOME MEASURES: Primary: daily morphine milligram equivalent (MME) opioid dosing calculated from prescriptions dispensed for 1 year before and after surgery; secondary: 90-day all-cause readmission and complications, 90-day acute postoperative pain, 90-day and 1-year reoperation, surgical costs, length of stay, and discharge disposition. METHODS: Distinct patient subgroups defined by patterns of daily MME pre- and postoperatively were identified via group-based trajectory modeling. Associations between these groups and outcomes were assessed with multivariable logistic regression with risk adjustment for patient and surgical factors. RESULTS: Among primary single level lumbar fusion patients, 59.5% filled an opioid prescription in the 3 months preceding surgery, whereas 40.5% were opioid naïve (Naïve). Five distinct subgroups of daily MME were identified among those filling opioids preoperatively: (1) Naïve to 3m (21.2% of patients): no opioids until 3 months preoperatively, escalating to 15 MME/day; (2) Low to 3m (11.4%): very low or as needed dose until 3 months preoperatively, escalating to 15 MME/day; (3) 6m Rise (6.9%): no opioids until 6 months preoperatively, escalating to >30 MME/day; (4) Medium (9.8%): increased linearly from 10 to 25 MME/day across the year before surgery; (5) High (10.0%): increased linearly from 60 to >80 MME/day across the year before surgery. These five preoperative opioid groups were related to postoperative opioids filled in a dose-response manner. The two preoperative patient groups with chronic Medium to High-dose opioid dosing were associated with increased adverse events, including all-cause readmission, reoperation, and pneumonia, whereas a low baseline group with a large, earlier preoperative rise in opioid dosing (6m Rise) had increased encounters for acute postoperative pain. Postoperatively, only 9.5% of patients did not fill an opioid prescription. Five distinct postoperative subgroups were identified based on their patterns in daily MME: Two groups ceased filling opioids within the year following surgery (33.6% of patients), and three groups declined in opioid dosage following surgery but plateaued at low (0-5 MME/day, 29.1%), medium (10-15 MME/day, 12.0%), or high (70-75 MME/day), 13.1%) doses by 1 year. Patients within the higher preoperative opioid groups were more likely to belong to the postoperative groups that were unable to cease filling opioids. CONCLUSIONS: Identification of a patient's preoperative time trend in daily opioid use may provide significant prognostic value and help guide pain management and risk reduction efforts. LEVEL OF EVIDENCE: III.

Introduction: Moral injury comprises feelings of guilt, despair, shame, and/or helplessness from having one's morals transgressed. Those underrepresented in health care are more likely to experience moral injury arising from micro- and macroaggressions. This workshop was designed for interprofessional health care providers ranging from students to program leadership to raise awareness about moral injury and provide tools to combat it. Methods: This 75-minute interactive workshop explored moral injury through a health care lens. It included components of lecture, case-based learning, small-group discussion, and individual reflection. Participants completed anonymous postworkshop evaluations, providing data on satisfaction and intention to change practice. We used descriptive statistics to analyze the quantitative data and applied content analysis to the qualitative data. Results: The workshop was presented at two local academic conferences. Data were collected from 34 out of 60 participants, for a response rate of 57%. Ninety-seven percent of participants felt the workshop helped them define and identify moral injury and was a valuable use of their time, as well as indicating they would apply the information learned in their daily life. One hundred percent would recommend the workshop to a friend or colleague. Almost half felt they could implement strategies to address moral injury after participating in the workshop. Discussion: This workshop proved to be a valuable tool to define and discuss moral injury. The materials can be adapted to a broad audience.

Axial skeletal injury and related illness is a major cause of medical disability and force attrition in deployed service members. Predeployment identification of at-risk personnel is unreliable. Risk of axial skeletal injury or illness during deployment is heterogeneous. Major spinal trauma casualties are uncommon, accounting for 1% of casualties, and are usually related to battle injuries. These major spinal injuries are often associated with multiple system/anatomic injuries. Spinal cord injuries account for 18% of major spinal injuries in persons with battle-related spinal injury. Non-battle spine pain, that is, back or neck area pain not associated with major trauma, is a significant force attrition problem, accounting for 40% of all combat casualty evacuation in some years. Personnel attrition due to neck and back pain not associated with major trauma is highly variable by unit and exposure, including psychological exposure. Return-to-duty rates for both traumatic and atraumatic spine injuries is poor (≤15%); this rate is predicted by psychological comorbidities.

STUDY DESIGN: A case-control study with prospectively collected samples for laboratory analysis in a series of patients with spinal fragility fractures and a series of patients without fracture who underwent fusion for LBP. OBJECTIVE: Was an exploratory data analysis for candidate cytokine biomarkers present in the fracture milieu of patients with persistent back pain associated with vertebral compression fracture. SUMMARY OF BACKGROUND DATA: Lumbar and thoracic compression fractures are common. Little is known about the presence of inflammatory mediators within fractured vertebra in the clinical setting. METHODS: Thirty patients diagnosed with a single thoracic or lumbar compression fracture were treated with single level vertebroplasty. At the time of intervention, needle aspiration was carried out at the fractured level. A multiplexed bead assay was used to assess the presence of 27 different cytokines and inflammatory mediators. A control group consisted of needle aspiration samples of 30 lumbar vertebra from 13 patients with chronic pain but no fracture undergoing open instrumented fusion. RESULTS: Thirty patients with 30 fractures consisted of 23 female and 7 male with a mean age of 77.5 years (SD 13.6; range 42 to 97) and a mean of 3.9 weeks of pain (SD 3.1; range 1 to 12). The highest levels of inflammatory mediators were (in order): IL-1 receptor antagonist, PDGF, RANTES, IP-10, IL-8, and eotaxin. These mediators were present at concentrations>200 pg/mL. Compared with controls with chronic pain, significant differences were present for 4 mediators: TNF, MIP-1b, IL-9, and IL-12. The panel of these 4 markers was 93.3% specific and 66.7% sensitive for fracture compared with the control group. CONCLUSIONS: Inflammatory mediators are present in needle aspirates of symptomatic vertebral compression fractures. Some of these mediators show different levels than in patients with chronic pain but no fracture. LEVEL OF EVIDENCE: Diagnostic level of evidence II.

OBJECTIVE: This abbreviated version of the American College of Occupational and Environmental Medicine's Low Back Disorders guideline reviews the evidence and recommendations developed for invasive treatments used to manage low back disorders. METHODS: Comprehensive systematic literature reviews were accomplished with article abstraction, critiquing, grading, evidence table compilation, and guideline finalization by a multidisciplinary expert panel and extensive peer-review to develop evidence-based guidance. Consensus recommendations were formulated when evidence was lacking and often relied on analogy to other disorders for which evidence exists. A total of 47 high-quality and 321 moderate-quality trials were identified for invasive management of low back disorders. RESULTS: Guidance has been developed for the invasive management of acute, subacute, and chronic low back disorders and rehabilitation. This includes 49 specific recommendations. CONCLUSION: Quality evidence should guide invasive treatment for all phases of managing low back disorders.

STUDY DESIGN: Observational cohort study. SUMMARY OF BACKGROUND DATA: Studies evaluating the treatment of presumed discogenic spine pain using nucleoplasty have reported variable success rates. It has been suggested that these procedures lower the intradiscal pressure, reduce disk protrusion, improve disk hydration, and restore disk height. It is proposed that such structural changes in treated disks correspond to the clinical improvement in patients. Radiographic and clinical evidence showing the efficacy of nucleoplasty remains inadequate. OBJECTIVE: To document the comparative changes in magnetic resonance imaging (MRI) the appearance of disk morphology as reflected by Pfirrmann classification scores before and after the nucleoplasty treatment in patients with continued symptoms. METHODS: Twenty-eight consecutive patients with persistent symptoms after nucleoplasty within 1 year of treatment were evaluated. Prenucleoplasty and postnucleoplasty MRIs were evaluated and Pfirrmann scores of the symptomatic level were determined. RESULTS: In all the treated patients, comparison between the prenucleoplasty and the postnucleoplasty MRI of the targeted disks failed to show increased signal hydration, disk space height improvement, or shrinkage of the preoperative disk bulge at a mean time of 6 months after the procedure. Of the 17 cervical levels treated in 12 patients, 5 seemed to show progressive degeneration at treated levels (42% of the patients). Of the 17 lumbar procedures in 16 patients, 4 seemed to show progressive degeneration (25% of the patients) and 1 developed a new spondylolisthesis (6.3%). Thus, 32% of the patients in our cohort showed progressive degeneration at the treated level. The median Pfirrmann score in both prenucleoplasty and postnucleoplasty was 2, and the mean Pfirrmann classification prenucleoplasty and postnucleoplasty was 1.8 and 2.1, respectively (P<0.05, 2-tailed t test). CONCLUSION: This study failed to detect any morphologic improvement of disk abnormalities by MRI evaluation in patients with persistent pain, who then underwent nucleoplasty. Thirty-two percent showed progressive degeneration in less than 1 year after nucleoplasty, a rate greater than expected by natural progression during the interval of examination.

PURPOSE: To characterize the inter- and intraobserver variability of qualitative, non-disk contour degenerative findings of the lumbar spine at magnetic resonance (MR) imaging. MATERIALS AND METHODS: The case accrual method used to perform this institutional review board-approved, HIPAA-compliant retrospective study was the random selection of 111 interpretable MR examination cases of subjects from the Spine Patient Outcomes Research Trial. The subjects were aged 18-87 years (mean, 53 years +/- 16 [standard deviation]). Four independent readers rated the cases according to defined criteria. A subsample of 40 MR examination cases was selected for reevaluation at least 1 month later. The following findings were assessed: spondylolisthesis, disk degeneration, marrow endplate abnormality (Modic changes), posterior anular hyperintense zone (HIZ), and facet arthropathy. Inter- and intraobserver agreement in rating the data was summarized by using weighted kappa statistics. RESULTS: Interobserver agreement was good (kappa = 0.66) in rating disk degeneration and moderate in rating spondylolisthesis (kappa = 0.55), Modic changes (kappa = 0.59), facet arthropathy (kappa = 0.54), and posterior HIZ (kappa = 0.44). Interobserver agreement in rating the extent of Modic changes was moderate: kappa Values were 0.43 for determining superior anteroposterior extent, 0.47 for determining superior craniocaudal extent, 0.57 for determining inferior anteroposterior extent, and 0.48 for determining inferior craniocaudal extent. Intraobserver agreement was good in rating spondylolisthesis (kappa = 0.66), disk degeneration (kappa = 0.74), Modic changes (kappa = 0.64), facet arthropathy (kappa = 0.69), and posterior HIZ (kappa = 0.67). Intraobserver agreement in rating the extent of Modic changes was moderate, with kappa values of 0.54 for superior anteroposterior, 0.60 for inferior anteroposterior, 0.50 for superior craniocaudal, and 0.60 for inferior craniocaudal extent determinations. CONCLUSION: The interpretation of general lumbar spine MR characteristics has sufficient reliability to warrant the further evaluation of these features as potential prognostic indicators.

STUDY DESIGN: Best-evidence synthesis. OBJECTIVE: To perform a best evidence synthesis on the course and prognostic factors for neck pain and its associated disorders in workers. SUMMARY OF BACKGROUND DATA: Knowledge of the course of neck pain in workers guides expectations for recovery. Identifying prognostic factors assists in planning effective workplace policies, formulating interventions and promoting lifestyle changes to decrease the frequency and burden of neck pain in the workplace. METHODS: The Bone and Joint Decade 2000-2010 Task Force on Neck Pain and its Associated Disorders (Neck Pain Task Force) conducted a critical review of the literature published between 1980 and 2006 to assemble the best evidence on neck pain and its associated disorders. Studies meeting criteria for scientific validity were included in a best evidence synthesis. RESULTS: We found 226 articles related to course and prognostic factors in neck pain and its associated disorders. After a critical review, 70 (31%) were accepted on scientific merit; 14 of these studies related to course and prognostic factors in working populations. Between 60% and 80% of workers with neck pain reported neck pain 1 year later. Few workplace or physical job demands were identified as being linked to recovery from neck pain. However, workers with little influence on their own work situation had a slightly poorer prognosis, and white-collar workers had a better prognosis than blue-collar workers. General exercise was associated with better prognosis; prior neck pain and prior sick leave were associated with poorer prognosis. CONCLUSION: The Neck Pain Task Force presents a report of current best evidence on course and prognosis for neck pain. Few modifiable prognostic factors were identified; however, having some influence over one's own job and being physically active seem to hold promise as prognostic factors.
RESUMO
STUDY DESIGN: Best evidence synthesis. OBJECTIVE: To critically appraise and synthesize the literature on assessment of neck pain. SUMMARY OF BACKGROUND DATA: The published literature on assessment of neck pain is large and of variable quality. There have been no prior systematic reviews of this literature. METHODS: The Bone and Joint Decade 2000-2010 Task Force on Neck Pain and Its Associated Disorders conducted a critical review of the literature (published 1980-2006) on assessment tools and screening protocols for traumatic and nontraumatic neck pain. RESULTS: We found 359 articles on assessment of neck pain. After critical review, 95 (35%) were judged scientifically admissible. Screening protocols have high predictive values to detect cervical spine fracture in alert, low-risk patients seeking emergency care after blunt neck trauma. Computerized tomography (CT) scans had better validity (in adults and elderly) than radiographs in assessing high-risk and/or multi-injured blunt trauma neck patients. In the absence of serious pathology, clinical physical examinations are more predictive at excluding than confirming structural lesions causing neurologic compression. One exception is the manual provocation test for cervical radiculopathy, which has high positive predictive value. There was no evidence that specific MRI findings are associated with neck pain, cervicogenic headache, or whiplash exposure. No evidence supports using cervical provocative discography, anesthetic facet, or medial branch blocks in evaluating neck pain. Reliable and valid self-report questionnaires are useful in assessing pain, function, disability, and psychosocial status in individuals with neck pain. CONCLUSION: The scientific evidence supports screening protocols in emergency care for low-risk patients; and CT-scans for high-risk patients with blunt trauma to the neck. In nonemergency neck pain without radiculopathy, the validity of most commonly used objective tests is lacking. There is support for subjective self-report assessment in monitoring patients' course, response to treatment, and in clinical research.
RESUMO
STUDY DESIGN: Best evidence synthesis. OBJECTIVE: To identify, critically appraise, and synthesize literature from 1980 through 2006 on noninvasive interventions for neck pain and its associated disorders. SUMMARY OF BACKGROUND DATA: No comprehensive systematic literature reviews have been published on interventions for neck pain and its associated disorders in the past decade. METHODS: We systematically searched Medline and screened for relevance literature published from 1980 through 2006 on the use, effectiveness, and safety of noninvasive interventions for neck pain and associated disorders. Consensus decisions were made about the scientific merit of each article; those judged to have adequate internal validity were included in our best evidence synthesis. RESULTS: Of the 359 invasive and noninvasive intervention articles deemed relevant, 170 (47%) were accepted as scientifically admissible, and 139 of these related to noninvasive interventions (including health care utilization, costs, and safety). For whiplash-associated disorders, there is evidence that educational videos, mobilization, and exercises appear more beneficial than usual care or physical modalities. For other neck pain, the evidence suggests that manual and supervised exercise interventions, low-level laser therapy, and perhaps acupuncture are more effective than no treatment, sham, or alternative interventions; however, none of the active treatments was clearly superior to any other in either the short- or long-term. For both whiplash-associated disorders and other neck pain without radicular symptoms, interventions that focused on regaining function as soon as possible are relatively more effective than interventions that do not have such a focus. CONCLUSION: Our best evidence synthesis suggests that therapies involving manual therapy and exercise are more effective than alternative strategies for patients with neck pain; this was also true of therapies which include educational interventions addressing self-efficacy. Future efforts should focus on the study of noninvasive interventions for patients with radicular symptoms and on the design and evaluation of neck pain prevention strategies.
RESUMO
STUDY DESIGN: Iterative discussion and consensus by a multidisciplinary task force scientific secretariat reviewing scientific evidence on neck pain and its associated disorders. OBJECTIVE: To provide an integrated model for linking the epidemiology of neck pain with its management and consequences, and to help organize and interpret existing knowledge, and to highlight gaps in the current literature. SUMMARY OF BACKGROUND DATA: The wide variability of scientific and clinical approaches to neck pain described in the literature requires a unified conceptual model for appropriate interpretation of the research evidence. METHODS: The 12-member Scientific Secretariat of the Bone and Joint Decade 2000-2010 Task Force on Neck Pain and Its Associated Disorders critically reviewed and eventually accepted as scientifically admissible a total of 552 scientific papers. The group met face-to-face on 18 occasions and had frequent additional telephone conference meetings over a 6-year period to discuss and interpret this literature and to agree on a conceptual model, which would accommodate findings. Models and definitions published in the scientific literature were discussed and repeatedly modified until the model and case definitions presented here were finally approved by the group. RESULTS: Our new conceptual model is centered on the person with neck pain or who is at risk for neck pain. Neck pain is viewed as an episodic occurrence over a lifetime with variable recovery between episodes. The model outlines the options available to individuals who are dealing with neck pain, along with factors that determine options, choices, and consequences. The short- and long-term impacts of neck pain are also considered. Finally, the model includes a 5-axis classification of neck pain studies based on how subjects were recruited into each study. CONCLUSION: The Scientific Secretariat found the conceptual model helpful in interpreting the available scientific evidence. We believe it can assist people with neck pain, researchers, clinicians, and policy makers in framing their questions and decisions.
RESUMO
STUDY DESIGN: Best evidence synthesis. OBJECTIVE: To identify, critically appraise, and synthesize literature from 1980 through 2006 on surgical interventions for neck pain alone or with radicular pain in the absence of serious pathologic disease. SUMMARY OF BACKGROUND DATA: There have been no comprehensive systematic literature or evidence-based reviews published on this topic. METHODS: We systematically searched Medline for literature published from 1980 to 2006 on percutaneous and open surgical interventions for neck pain. Publications on the topic were also solicited from experts in the field. Consensus decisions were made about the scientific merit of each article; those judged to have adequate internal validity were included in our Best Evidence Synthesis. RESULTS: Of the 31,878 articles screened, 1203 studies were relevant to the Neck Pain Task Force mandate and of these, 31 regarding treatment by surgery or injections were accepted as scientifically admissible. Radiofrequency neurotomy, cervical facet injections, cervical fusion and cervical arthroplasty for neck pain without radiculopathy are not supported by current evidence. We found there is support for short-term symptomatic improvement of radicular symptoms with epidural corticosteroids. It is not clear from the evidence that long-term outcomes are improved with the surgical treatment of cervical radiculopathy compared to nonoperative measures. However, relatively rapid and substantial symptomatic relief after surgical treatment seems to be reliably achieved. It is not evident that one open surgical technique is clearly superior to others for radiculopathy. Cervical foramenal or epidural injections are associated with relatively frequent minor adverse events (5%-20%); however, serious adverse events are very uncommon (<1%). After open surgical procedures on the cervical spine, potentially serious acute complications are seen in approximately 4% of patients. CONCLUSION: Surgical treatment and limited injection procedures for cervical radicular symptoms may be reasonably considered in patients with severe impairments. Percutaneous and open surgical treatment for neck pain alone, without radicular symptoms or clear serious pathology, seems to lack scientific support.
RESUMO
STUDY DESIGN: Best evidence synthesis. OBJECTIVE: To provide evidence-based guidance to primary care clinicians about how to best assess and treat patients with neck pain. SUMMARY OF BACKGROUND DATA: There is a need to translate the results of clinical and epidemiologic studies into meaningful and practical information for clinicians. METHODS: Based on best evidence syntheses of published studies on the risk, prognosis, assessment, and management of people with neck pain and its associated disorders, plus additional research projects and focused literature reviews reported in this supplement, the 12-member multidisciplinary Scientific Secretariat of the Neck Pain Task Force followed a 4-step approach to develop practical guidance for clinicians. RESULTS: The Neck Pain Task Force recommends that people seeking care for neck pain should be triaged into 4 groups: Grade I neck pain with no signs of major pathology and no or little interference with daily activities; Grade II neck pain with no signs of major pathology, but interference with daily activities; Grade III neck pain with neurologic signs of nerve compression; Grade IV neck pain with signs of major pathology. In the emergency room after blunt trauma to the neck, triage should be based on the NEXUS criteria or the Canadian C-spine rule. Those with a high risk of fracture should be further investigated with plain radiographs and/or CT-scan. In ambulatory primary care, triage should be based on history and physical examination alone, including screening for red flags and neurologic examination for signs of radiculopathy. Exercises and mobilization have been shown to provide some degree of short-term relief of Grade I or Grade II neck pain after a motor vehicle collision. Exercises, mobilization, manipulation, analgesics, acupuncture, and low-level laser have been shown to provide some degree of short-term relief of Grade I or Grade II neck pain without trauma. Those with confirmed Grade III and severe persistent radicular symptoms might benefit from corticosteroid injections or surgery. Those with confirmed Grade IV neck pain require management specific to the diagnosed pathology. CONCLUSION: The best available evidence suggests initial assessment for neck pain should focus on triage into 4 grades, and those with common neck pain (Grade I and Grade II) might be offered the listed noninvasive treatments if short-term relief is desired.
RESUMO
STUDY DESIGN: Best evidence synthesis. OBJECTIVE: To report on gaps in the literature and make methodologic recommendations based on our review of the literature on frequency and risk factors, assessment, intervention, and course and prognostic factors for neck pain and its associated disorders. SUMMARY OF BACKGROUND DATA: The scientific literature on neck pain is large and of variable quality. We reviewed 1203 studies and judged 46% to be of sufficient scientific validity to be included in the best evidence synthesis. Scientific quality varied across study topics, and fundamental questions remain about important issues. METHODS: The Bone and Joint Decade 2000-2010 Task Force on Neck Pain and its Associated Disorders (Neck Pain Task Force) conducted a critical review of the literature published between 1980 and 2006 to assemble the best evidence on neck pain and its associated disorders. Studies meeting criteria for scientific validity were included in a best evidence synthesis. RESULTS: We outline a large number of gaps in the current literature. For example, we found important gaps in our knowledge about neck pain in children (risk factors, screening criteria to rule out serious injury, management, course and prognosis); and in the prevention of neck pain-related activity limitations. Few studies addressed the impact of culture or social policies (such as governmental health policies or insurance compensation policies) on neck pain. A number of important questions remain about the effectiveness of commonly used interventions for neck pain. CONCLUSION: The Neck Pain Task Force undertook a best evidence synthesis to establish a baseline of the current best evidence on the course and prognosis for whiplash-associated disorders. We identify a number of gaps in the current knowledge, and provide recommendations for the conduct of future studies.
RESUMO
STUDY DESIGN: Systematic review and best evidence synthesis. OBJECTIVES: To describe the prevalence and incidence of neck pain and disability in workers; to identify risk factors for neck pain in workers; to propose an etiological diagram; and to make recommendations for future research. SUMMARY OF BACKGROUND DATA: Previous reviews of the etiology of neck pain in workers relied on cross-sectional evidence. Recently published cohorts and randomized trials warrant a re-analysis of this body of research. METHODS: We systematically searched Medline for literature published from 1980-2006. Retrieved articles were reviewed for relevance. Relevant articles were critically appraised. Articles judged to have adequate internal validity were included in our best evidence synthesis. RESULTS: One hundred and nine papers on the burden and determinants of neck pain in workers were scientifically admissible. The annual prevalence of neck pain varied from 27.1% in Norway to 47.8% in Québec, Canada. Each year, between 11% and 14.1% of workers were limited in their activities because of neck pain. Risk factors associated with neck pain in workers include age, previous musculoskeletal pain, high quantitative job demands, low social support at work, job insecurity, low physical capacity, poor computer workstation design and work posture, sedentary work position, repetitive work and precision work. We found preliminary evidence that gender, occupation, headaches, emotional problems, smoking, poor job satisfaction, awkward work postures, poor physical work environment, and workers' ethnicity may be associated with neck pain. There is evidence that interventions aimed at modifying workstations and worker posture are not effective in reducing the incidence of neck pain in workers. CONCLUSION: Neck disorders are a significant source of pain and activity limitations in workers. Most neck pain results from complex relationships between individual and workplace risk factors. No prevention strategies have been shown to reduce the incidence of neck pain in workers.
RESUMO
STUDY DESIGN: Best evidence synthesis. OBJECTIVE: To undertake a best evidence synthesis on course and prognosis of neck pain and its associated disorders in the general population. SUMMARY OF BACKGROUND DATA: Knowing the course of neck pain guides expectations for recovery. Identifying prognostic factors assists in planning public policies, formulating interventions, and promoting lifestyle changes to decrease the burden of neck pain. METHODS: The Bone and Joint Decade 2000-2010 Task Force on Neck Pain and its Associated Disorders (Neck Pain Task Force) conducted a critical review of literature published between 1980 and 2006 to assemble the best evidence on neck pain. Findings from studies meeting criteria for scientific validity were abstracted into evidence tables and included in a best evidence synthesis. RESULTS: We found 226 articles on the course and prognostic factors in neck pain and its associated disorders. After critical review, 70 (31%) of these were accepted on scientific merit. Six studies related to course and 7 to prognostic factors in the general population. Between half and three quarters of persons in these populations with current neck pain will report neck pain again 1 to 5 years later. Younger age predicted better outcome. General exercise was unassociated with outcome, although regular bicycling predicted poor outcome in 1 study. Psychosocial factors, including psychologic health, coping patterns, and need to socialize, were the strongest prognostic factors. Several potential prognostic factors have not been well studied, including degenerative changes, genetic factors, and compensation policies. CONCLUSION: The Neck Pain Task Force undertook a best evidence synthesis to establish a baseline of the current best evidence on the course and prognosis for this symptom. General exercise was not prognostic of better outcome; however, several psychosocial factors were prognostic of outcome.
RESUMO
STUDY DESIGN: Best evidence synthesis. OBJECTIVE: To perform a best evidence synthesis on the course and prognostic factors for neck pain and its associated disorders in Grades I-III whiplash-associated disorders (WAD). SUMMARY OF BACKGROUND DATA: Knowledge of the course of recovery of WAD guides expectations for recovery. Identifying prognostic factors assists in planning management and intervention strategies and effective compensation policies to decrease the burden of WAD. METHODS: The Bone and Joint Decade 2000-2010 Task Force on Neck Pain and its Associated Disorders (Neck Pain Task Force) conducted a critical review of the literature published between 1980 and 2006 to assemble the best evidence on neck pain and its associated disorders. Studies meeting criteria for scientific validity were included in a best evidence synthesis. RESULTS: We found 226 articles related to course and prognostic factors in neck pain and its associated disorders. After a critical review, 70 (31%) were accepted on scientific merit; 47 of these studies related to course and prognostic factors in WAD. The evidence suggests that approximately 50% of those with WAD will report neck pain symptoms 1 year after their injuries. Greater initial pain, more symptoms, and greater initial disability predicted slower recovery. Few factors related to the collision itself (for example, direction of the collision, headrest type) were prognostic; however, postinjury psychological factors such as passive coping style, depressed mood, and fear of movement were prognostic for slower or less complete recovery. There is also preliminary evidence that the prevailing compensation system is prognostic for recovery in WAD. CONCLUSION: The Neck Pain Task Force undertook a best evidence synthesis to establish a baseline of the current best evidence on the course and prognosis for WAD. Recovery of WAD seems to be multifactorial.
RESUMO
STUDY DESIGN: Best evidence synthesis. OBJECTIVE: To provide a detailed description of the methods undertaken in a systematic search and perform a best evidence synthesis on the frequency, determinants, assessment, interventions, course and prognosis of neck pain, and its associated disorders. SUMMARY OF BACKGROUND DATA: Neck pain is an important cause of health burden; however, the published information is vast, and stakeholders would benefit from a summary of the best evidence. METHODS: The Bone and Joint Decade 2000-2010 Task Force on Neck Pain and its Associated Disorders conducted a systematic search and critical review of the literature published between 1980 and 2006 to assemble the best evidence on neck pain. Citations were screened for relevance to the Neck Pain Task Force mandate, using a priori criteria, and relevant studies were critically reviewed for their internal scientific validity. Findings from studies meeting criteria for scientific validity were synthesized into a best evidence synthesis. RESULTS: We found 31,878 citations, of which 1203 were relevant to the mandate of the Neck Pain Task Force. After critical review, 552 studies (46%) were judged scientifically admissible and were compiled into the best evidence synthesis. CONCLUSION: The Bone and Joint Decade 2000-2010 Task Force on Neck Pain and its Associated Disorders undertook a best evidence synthesis to establish a baseline of the current best evidence on the epidemiology, assessment and classification of neck pain, as well as interventions and prognosis for this symptom. This article reports the methods used and the outcomes from the review. We found that 46% of the research literature was of acceptable scientific quality to inform clinical practice, policy-making, and future research.
