Beyond symptom resolution: insurance case manager's perspective on predicting recovery after motor vehicle crash.

PURPOSE: Insurance company case managers can play a critical role in the rehabilitation process of people with musculoskeletal disorders sustained following minor motor vehicle crash injury due to their interaction with multiple stakeholders and their role in approving various services. This study aimed to identify factors that case managers perceive as predictive of recovery in people with musculoskeletal disorders after minor motor vehicle crash injury. MATERIALS AND METHODS: To explore the perspectives of cases managers in Australia and the United States, semi-structured interviews explored factors that case managers thought provided an early indication of likely recovery outcomes in people with musculoskeletal disorders after minor motor vehicle crash injury. A framework analysis was applied and factors were displayed within the ICF-framework. RESULTS: Case managers (n = 40) demonstrated a broad, detailed understanding of biopsychosocial and contextual issues influencing recovery. They emphasized the importance of the injured worker's expressed affect and motivation, style of communication, the role of lawyers, the worker's family and friends, as well as cultural and geographic influences. The overarching themes perceived as having a major influence on recovery outcomes were general health, pain processing and response, work situation, and compensation entitlement. CONCLUSIONS: Case managers' broad and detailed perceptions about recovery may provide additional, valuable perspectives for professionals involved in the rehabilitation process of people with musculoskeletal disorders after minor motor vehicle crash injury. Further research needs to be conducted to explore the effects of case manager involvement in the process of recovery.Implications for rehabilitationInsurance Case Managers identified multiple factors including affect and motivation, style of communication, the role of lawyers, family and friends, cultural and geographic variation provide opportunities for more effective treatment of people with musculoskeletal disorders related to minor motor vehicle collisions. These managers' perceptions about recovery may be informative to and provide opportunities for health professionals involved in the rehabilitation of people with musculoskeletal disorders related to minor motor vehicle collisions.While the Insurance Case Managers involved in this research did not use formalized assessment techniques, tools and assessment protocols could be developed jointly between for the needs of Insurance Case Managers and other stakeholders to tackle recovery of people with musculoskeletal disorders related to minor motor vehicle collision.

Association between social factors and performance during Functional Capacity Evaluations: a systematic review.

Purpose: Determine the association of different social factors with Functional Capacity Evaluation (FCE) performance in adults. Materials and methods: A systematic literature search was performed in MEDLINE, CINAHL, and PsycINFO electronic databases. Studies were eligible if they studied social factor's association with the performance of adults undergoing FCE. Studies were assessed on methodological quality and quality of evidence. The review was performed using best-evidence synthesis methods. Results: Thirteen studies were eligible and 11 social factors were studied. Considerable heterogeneity regarding measurements, populations, and methods existed among the studies. High quality of evidence was found for the association of FCE performance with the country of FCE and examiner's fear behavior; moderate quality of evidence with previous job salary; and low or very low quality of evidence with compensation status, litigation status, type of instruction, time of day (workday), primary or mother language, and ethnicity. Other social factors were not studied. Conclusions: Evidence for associations of various social factors with FCE performance was found, but robust conclusions about the strength of the associations cannot be made. Quality of evidence ranged from high to very low. Further research on social factors, also within a biopsychosocial context, is necessary to provide a better understanding of FCE performance. Implications for Rehabilitation Research on Functional Capacity Evaluation (FCE) performance and its association with biopsychosocial factors have scarcely addressed the impact of social factors, limiting full understanding of FCE results. The social factors, healthcare (examiner's fear behavior and type of instruction), personal or cultural systems (country of FCE, primary or mother language, and ethnicity), workplace system (previous job salary, time of day (workday)), and legislative and insurance system (compensation and litigation status), have a bearing in FCE performance. Better understanding of factors associating with functional capacity provide insights in FCE, allowing clinicians to improve the evaluations and interpretations of the assessment and better design the rehabilitation program. Better understanding of factors that influence FCE performance, and of unstudied factors, will allow researchers guidance to further investigate the construct of functional capacity.

Functional Capacity Evaluation in Different Societal Contexts: Results of a Multicountry Study.

Purpose To examine factors associated with Functional Capacity Evaluation (FCE) results in patients with painful musculoskeletal conditions, with focus on social factors across multiple countries. Methods International cross-sectional study was performed within care as usual. Simple and multiple multilevel linear regression analyses which considered measurement's dependency within clinicians and country were conducted: FCE characteristics and biopsychosocial variables from patients and clinicians as independent variables; and FCE results (floor-to-waist lift, six-minute walk, and handgrip strength) as dependent variables. Results Data were collected for 372 patients, 54 clinicians, 18 facilities and 8 countries. Patients' height and reported pain intensity were consistently associated with every FCE result. Patients' sex, height, reported pain intensity, effort during FCE, social isolation, and disability, clinician's observed physical effort, and whether FCE test was prematurely ended were associated with lift. Patient's height, Body Mass Index, post-test heart-rate, reported pain intensity and effort during FCE, days off work, and whether FCE test was prematurely ended were associated with walk. Patient's age, sex, height, affected body area, reported pain intensity and catastrophizing, and physical work demands were associated with handgrip. Final regression models explained 38‒65% of total variance. Clinician and country random effects composed 1-39% of total residual variance in these models. Conclusion Biopsychosocial factors were associated with every FCE result across multiple countries; specifically, patients' height, reported pain intensity, clinician, and measurement country. Social factors, which had been under-researched, were consistently associated with FCE performances. Patients' FCE results should be considered from a biopsychosocial perspective, including different social contexts.

Development of a Modified Version of the Spinal Function Sort (M-SFS): A Mixed Method Approach.

Purpose To develop a modified version of the spinal function sort (M-SFS) by measuring work-related self-efficacy beliefs in patients with chronic low back pain. Methods A mixed method design consisting of three different methods (M1-3) was performed. In semi-structured interviews participants were asked how often they performed the activities of the 50 SFS items in 1 week, and which spinal postures and movements were associated with their back pain (M1). Quantitative analysis of previously obtained SFS data investigated internal consistency, unidimensionality, item response, and floor and ceiling effect (M2). Experts rated the SFS items based on their relevance (M3). The findings from these methods were used within a final scoring system for item reduction. Results From semi-structured interviews with 17 participants, eight new items emerged (M1). Quantitative analysis of 565 data sets (M2) revealed very high internal consistency of all items (Cronbach's alpha = 0.98) indicating item redundancy; unidimensionality of the SFS was supported by principal component analysis; good item response was confirmed by Rasch analysis; and a floor effect of four items depicting very heavy material handling was found. Experts agreed on 8 out of the 50 SFS as relevant (M3). From the original SFS, 12 items met the predefined summary score of 9. Conclusions A modified version of the SFS with 20 items has been developed. Feasibility, reliability and validity of this modified version must be tested before it can be used in clinical practice.

Can functional capacity tests predict future work capacity in patients with whiplash-associated disorders?

OBJECTIVE: To determine whether functional capacity evaluation (FCE) tests predict future work capacity (WC) of patients with whiplash-associated disorders (WADs) grades I and II who did not regain full WC 6 to 12 weeks after injury. DESIGN: Prospective cohort study. SETTING: Rehabilitation center. PARTICIPANTS: Workers (N=267) listed on workers' compensation with grade I or II WADs 6 to 12 weeks after injury. INTERVENTIONS: Patients performed 8 work-related FCE tests. MAIN OUTCOME MEASURES: WC (0-100%) measured at baseline and 1, 3, 6, and 12 months after testing. Correlation coefficients between FCE tests and WC were calculated. A linear mixed-model analysis was used to assess the association between FCE and future WC. RESULTS: Mean ± SD WC increased over time from 20.8%±27.6% at baseline to 32.3%±38.4%, 51.3%±42.8%, 65.6%±42.2%, and 83.2%±35.0% at the 1-, 3-, 6-, and 12-month follow-ups, respectively. Correlation coefficients between FCE tests and WC ranged from r=.06 (lifting low at 12-mo follow-up) to r=.39 (walking speed at 3mo). Strength of the correlations decreased over time. FCE tests did not predict WC at follow-up. The predictors of WC were ln (time) (ß=23.74), mother language (ß=5.49), WC at baseline (ß=1.01), and self-reported disability (ß=-.20). Two interaction terms, ln (time) × WC (ß=-.19) and ln (time) × self-reported disability (ß=-.21), were significant predictors of WC. CONCLUSIONS: FCE tests performed within 6 to 12 weeks after WADs injury grades I and II are associated with WC at baseline but do not predict future WC, whereas time course, mother language, WC at baseline, and self-reported disability do predict future WC. Additionally, the interaction between time course WC at baseline and self-reported disability predicted future WC.

Which instruments can detect submaximal physical and functional capacity in patients with chronic nonspecific back pain? A systematic review.

STUDY DESIGN: Systematic review. OBJECTIVE: To evaluate the validity of instruments that claim to detect submaximal capacity when maximal capacity is requested in patients with chronic nonspecific musculoskeletal pain. SUMMARY OF BACKGROUND DATA: Several instruments have been developed to measure capacity in patients with chronic pain. The detection of submaximal capacity can have major implications for patients. The validity of these instruments has never been systematically reviewed. METHODS: A systematic literature search was performed including the following databases: Web of Knowledge (including PubMed and Cinahl), Scopus, and Cochrane. Two reviewers independently selected the articles based on the title and abstract according to the study selection criteria. Studies were included when they contained original data and when they objectified submaximal physical or functional capacity when maximal physical or functional capacity was requested. Two authors independently extracted data and rated the quality of the articles. The included studies were scored according to the subscales "Criterion Validity" and "Hypothesis Testing" of the COSMIN checklist. A Best Evidence Synthesis was performed. RESULTS: Seven studies were included, 5 of which used a reference standard for submaximal capacity. Three studies were of good methodological quality and validly detected submaximal capacity with specificity rates between 75% and 100%. CONCLUSION: There is strong evidence that submaximal capacity can be detected in patients with chronic low back pain with a lumbar motion monitor or visual observations accompanying a functional capacity evaluation lifting test.
