Factors associated with referral to physiotherapists for adult patients consulting for musculoskeletal disorders in primary care; an ancillary study to ECOGEN.

BACKGROUND: Musculoskeletal disorders (MSD) are multifactorial requiring multidisciplinary treatment including physiotherapy. General practitioners (GP) have a central role in managing MSDs and mostly solicit physiotherapists accounting for 76.1% of physiotherapy referrals in France. Patient, physician, and contextual factors, including healthcare accessibility, can influence physiotherapy referral rates. OBJECTIVE: To identify patient, physician, and contextual factors associated with physiotherapy referral in adult patients with MSDs in general practice. METHODS: This study is based on the 2011/2012 French cross-sectional ECOGEN study. Analyses included working-age patients consulting their GP for any MSD. Physiotherapy referral was assessed initially, then adjusted multilevel logistic model analysis of patient, physician, geographical area-related factors associated with these referrals was performed. RESULTS: Among the 2305 patients included, 456 (19.8%) were referred to a physiotherapist. Following multilevel multivariate analyses, physiotherapist referral was more frequent for female patients (OR 1.28; 95% CI [1.03, 1.59]) with spinal (OR 1.47; 95% CI [1.18, 1.83]) and upper limb disorders (OR 1.66; 95% CI [1.20, 2.29]), and less frequent for patients ≥ 50 years (OR 0.69; 95% CI [0.52, 0.91]), living in deprived geographical areas (OR 0.60; 95% CI [0.40, 0.90]). GPs referred to a physiotherapist less frequently if they were ≥ 50 years (OR 0.50; 95% CI [0.39, 0.63]), had a high number of annual consultations, or were practicing in semi-urban area in a multidisciplinary team. CONCLUSION: This multilevel analysis identifies factors associated with physiotherapy referral for patients with MSDs, including living in deprived geographical areas. This constitutes an original contribution towards addressing healthcare disparities.

Identification of actions to be taken by managers to facilitate the return to work of cancer survivors: Consensus between managers and cancer survivors.

BACKGROUND: Managers are considered to be main stakeholders in the return to work (RTW) of cancer survivors. However, the perspectives of cancer survivors and managers differ on what managerial actions should be taken during the RTW of cancer survivors. This difference might put effective collaboration and successful RTW at risk. Therefore, this study aims to reach consensus among managers and cancer survivors on the managerial actions to be taken during the four different RTW phases of cancer survivors (i.e., Disclosure, Treatment, RTW plan, Actual RTW). METHODS: The Technique for Research of Information by Animation of a Group of Experts (TRIAGE) was implemented with managers and cancer survivors (hereafter referred to as "experts"). An initial list of 24 actions was derived from a previous study. Firstly, for each action, fifteen experts were asked to indicate individually how important this action is per RTW phase (Likert scale from 1 - "Not important at all" to 6 - "Very important"). Consensus was reached when ≥ 80% (i.e., ≥ twelve experts) of the experts rated that action ≥5. Secondly, for each phase of the RTW process, the 15 actions with the highest percentage were discussed with eight experts during the collective consultation, except for the actions that already reached consensus. After discussion, the experts voted whether each action was important ("yes" / "no") and consensus required ≥ 87.5% (i.e., ≥ seven experts) of the experts to consider an action as important. RESULTS: Twenty-five managerial actions were finally retained for at least one of the RTW phases, e.g., Disclosure: "respect privacy" and "radiate a positive attitude", Treatment: "show appreciation" and "allow sufficient sick leave", RTW Plan: "tailor" and "communicate", and Actual RTW: "support practically" and "balance interest". CONCLUSION: Cancer survivors and managers reached consensus on the importance of 25 managerial actions, distributed into each phase of the RTW process. These actions should be considered an interplay of managerial actions by different stakeholders on the part of the employer (e.g., direct supervisor, HR-manager), and should be a responsibility that is shared by these stakeholders. The collective implementation of these actions within the company will help cancer survivors feel fully supported.

The impact of psoriasis on professional life: PsoPRO, a French national survey.

BACKGROUND: The physical, social and mental burden of psoriasis is well known, but its occupational impact has been less investigated. OBJECTIVE: To assess the impact of psoriasis on the working life of patients compared with the general population. METHODS: A national survey compared people with and without psoriasis using online questionnaires. In addition to the demographic, medical and professional characteristics, data on recent absenteeism and presenteeism were captured using the validated WPAI-PSO questionnaire. RESULTS: The patient sample comprised 714 with psoriasis (PsO), including 81 treated with systemic therapies (PsoST), and 84 with associated psoriatic arthritis (PsO + PsA). The control sample comprised 604 active subjects representative of the French population. Compared to controls, the impact of the disease on working life was no greater in PsO patients. Conversely, unemployment within the past 5 years and mean number of sick leaves within the previous year were more frequent in PsO + PsA. In patients with active psoriasis skin lesions, all aspects of the WPAI questionnaire were negatively impacted in PsoST and PsO + PsA patients, but not in PsO patients: Levels of absenteeism were 3.3% in controls, 5.6% in PsO (NS), 8.3% in PsoST (P < 0.05) and 13.0% in Ps0 + PsA (P < 0.05); impairment in presenteeism reached 27.0%, 21.2% (NS), 43.5% (P < 0.05) and 53.2% (P < 0.05), respectively, while overall work impairment was 27.9%, 22.2% (NS), 46.3% (P < 0.05) and 57.6% (P < 0.05), respectively. Nevertheless, a higher proportion of PsoST and PsO + PsA patients reported that work was more important than any other activity in their life. CONCLUSION: The occupational impact of psoriasis is important and significant in patients who receive systemic therapy or have concurrent PsA but minimal or absent in other psoriasis patients. The findings show that psoriasis patients have a high level of motivation to work.

Occupational prognosis factors for ulnar nerve entrapment at the elbow: A systematic review.

Although ulnar nerve entrapment is the second most common entrapment neuropathy, there is a dearth of studies identifying occupational prognosis factors. We carried out a systematic review of the occupational prognosis factors for ulnar nerve entrapment in order to identify professions at risks and allow better follow-up for their workers. Using the key words, "ulnar OR cubital", "neuropathy OR tunnel", and "work OR occupational" without limitations, original prospective studies were selected from four databases (PubMed, Embase, Web of Science, Cochrane Library) after two rounds (valid design, valid prognosis outcome reported, valid work exposure). Associations between prognosis for ulnar neuropathy and occupational factors were extracted and analyzed qualitatively. Dating from 1981 to 2013, three prospective studies were included; 1420 cases of ulnar nerve entrapment were followed for an average of 4 years and occupational exposure was retrieved. The only high-quality study (related to this question) found a significant relationship between occupational exposure and prognosis with an odds ratio for ulnar nerve entrapment of 1.78 (1.10-2.88). The two other studies were less focused on the occupational prognosis factors; one found that work activity requiring effort had worse prognosis after surgery, while the other found no significant relationship between occupational hand exposure and prognosis. Occupations requiring high effort may be associated with more severe ulnar neuropathies, but further studies (exposure as well as associated disorders) are mandatory for clinicians to provide work task information to their patients.

Work-related discussions between French rheumatologists and their rheumatoid arthritis patients.

BACKGROUND: Rheumatoid arthritis (RA) causes significant impairment of physical function, and thus adversely affects patients' ability to work. AIMS: To document how often work limitations are discussed by rheumatologists and RA patients during consultations. METHODS: We conducted an observational study in a sample of French rheumatologists and in a parallel sample of patients recruited by pharmacists. We asked all rheumatologists in France practising in private practice or mixed practice (private practice and hospital) to participate in a telephone survey about their most recent consultation with an RA patient. Randomly selected pharmacists recruited RA patients to complete a questionnaire about their most recent consultation with their rheumatologist. We included patients aged 20-59, with a paid job or unemployed. We calculated the proportion of consultations including work-related discussions in both samples. RESULTS: Of the 1737 rheumatologists contacted, 153 (9%) described consultations with eligible patients. Of the 1200 pharmacists contacted, 39 (3%) recruited 81 RA patients. The proportion of consultations including work-related discussions was 50% [95% confidence interval (CI) 42-58%] in the rheumatologist sample and 52% (95% CI 41-63%) in the patient sample. The most frequent subject of discussion (88%) was physical problems related to work in both samples. CONCLUSIONS: This is the first study to document the proportion of consultations where rheumatologists and their RA patients discuss work. Both specialists and patients reported that work was discussed in one in every two consultations.

Evolution of psychosocial factors at work in a French region.

BACKGROUND: Psychosocial factors at work (PFW) can be defined as all non-physicochemical occupational risks. Several epidemiological models have been proposed to measure PFW, but one of the most widely used is Karasek's model. AIMS: To determine whether psychosocial factors, evaluated by Karasek's questionnaire, had increased in a cohort of workers. METHODS: A random sample of workers in the Pays de la Loire region of France, who could be considered representative of the region's population of salaried workers, filled in a self-administered questionnaire, including Karasek's self-administered questionnaire, in 2002-05 and 2007-09. Karasek's questionnaire can be used to study three psychosocial dimensions (psychological demand, decision latitude and social support in the workplace) in workers in order to define two high-risk situations for their health: 'Job Strain' and 'Iso Strain'. Changes in job strain and iso strain among workers were studied according to the workers' sociodemographic characteristics and their working conditions. RESULTS: In this sample of 2049 workers, the proportion with iso strain increased between the two periods from 12 to 16%, P < 0.001, mainly among manual workers. Deterioration of Karasek indicators was mainly explained by an increase of the 'low social support' dimension (38 versus 49%, P < 0.001). Working conditions such as temporary employment of colleagues and high perceived physical exertion were associated with higher PFW. CONCLUSIONS: This study, based on a quantitative and collective model, showed deterioration of working team environments and increased risk for individual mental health in this cohort of French workers in recent years.

Pre-employment examination for low back risk in workers exposed to manual handling of loads: French guidelines.

BACKGROUND: Low back pain (LBP) is a major cause of sickness absence and disability in the working population, and the pre-employment examination should insure that worker's state of health is compatible with the requirements of proposed job. This paper summarizes the main recommendations of the good practice guidelines of the French Society of Occupational Medicine for pre-employment examination in workers exposed to manual handling of loads apart from pre-employment test. METHODS: The recommendations were developed according to the Clinical Practice Guidelines proposed by the French National Health Authority and based on a systematic search of the literature 1990-2012 in several databases. The guidelines were written and reviewed by two multidisciplinary committees. On the basis of the level of evidence in the literature, the proposed guidelines are classified as grade A, B, C or expert consensus. RESULTS: The main recommendations of these guidelines are as follows: (1) medical contraindications alone should not exclude employment in a job associated with a low back risk on the basis of a history of "simple" nonspecific LBP; (2) the relevance of examining a previous history of LBP, which is the best predictor of future LBP due to the recurrent nature of LBP. CONCLUSIONS: These guidelines correspond to a constant concern with prevention of occupational risk. Primarily intended for occupational physicians, they are also intended for general practitioners who carry out pre-employment examinations in many countries and are likely to be increasingly faced with this type of situation because of the combination of increasing work constraints with ageing of the workforce.

Chronic low back pain among French healthcare workers and prognostic factors of return to work (RTW): a non-randomized controlled trial.

BACKGROUND: Many factors influence the return to work of workers with chronic low back pain (CLBP). They have been said to vary according to socio-professional group. This study first aimed to compare prognostic factors influencing the return to work of CLBP healthcare workers (HCWs) and other workers (non-HCWs) after rehabilitation coupled with an occupational intervention. The second objective was to improve the evolution of indicators such as clinical examination, psychosocial impact and pain impact. METHODS: Between 2007 and 2012, a cohort of 217 CLBP workers (54.8 %-women; mean age = 41.3 ± 9.5 years, 118 non-HCWs; 99 HCWs mainly from the public sector) was included in an ambulatory rehabilitation program (standard physiotherapy or intensive network physiotherapy) coupled with an occupational intervention. Workers completed a questionnaire and had a clinical examination at baseline and after 24 months' follow up. Physical, social and occupational data was collected at the same time. Statistical analyses were performed to evaluate prognostic factors for return to work and compare the two worker populations. RESULTS: There was no difference between groups for the rate of OP (occupational physician) intervention or type of physiotherapy. 77.3 % of workers returned to work after 2 years following inclusion. To be an HCW (OR 0.1; 95 % CI [0.03-0.34]), to have less than 112 sick- leave days (OR 1.00; 95 % CI [0.93-1.00]), a small fingertip-floor distance (OR 0.96; 95 % CI [0.93-0.99]), a low anxiety/depression score (OR 0.97; 95 % CI [0.95-1.00]), a low impact of CLBP on daily life (OR 0.96; 95 % CI [0.93-1.00]), and on quality of life (OR 0.98; 95 % CI [0.95-1.00]) at baseline were statistically associated with return to work after 2 years of follow up. Only the profession (workplace) was statistically associated with return to work after 2 years of follow up using multivariate analysis. CONCLUSION: To our knowledge, this is the first cohort study concerning predictive factors of RTW among CLBP workers after 2 years of follow up. Interventions in the work environment did not seem to predict job retention significantly. But only 50 % of the employees in both groups (HCW and non-HCW) had one intervention at their workplace after 2 years. This study underlined the fact that the type of physiotherapy with a well-trained physiotherapist used to take care of CLBP could not impact on the RTW forecast. To develop these initial results, it might be interesting to study the comparison between private and public sectors and to randomize the physiotherapeutic intervention.

Pre-return-to-work medical consultation for low back pain workers. Good practice recommendations based on systematic review and expert consensus.

OBJECTIVES: The pre-return-to-work medical consultation during sick leave for low back pain (LBP) aims at assessing the worker's ability to resume working without risk for his/her health, and anticipating any difficulties inherent to returning to work and job retention. This article summarizes the good practices guidelines proposed by the French Society of Occupational Medicine (SFMT) and the French National Health Authority (HAS), and published in October 2013. METHODS: Good practices guidelines developed by a multidisciplinary and independent task force (24 experts) and peer review committee (50 experts) based on a literature review from 1990 to 2012, according to the HAS methodology. RESULTS: According to the labour regulations, workers can request a medical consultation with their occupational physician at any time. The pre-return-to-work consultation precedes the effective return-to-work and can be requested by the employee regardless of their sick leave duration. It must be scheduled early enough to: (i) deliver reassuring information regarding risks to the lower back and managing LBP; (ii) evaluate prognostic factors of chronicity and prolonged disability in relations to LBP and its physical, social and occupational consequences in order to implement the necessary conditions for returning to work; (iii) support and promote staying at work by taking into account all medical, social and occupational aspects of the situation and ensure proper coordination between the different actors. CONCLUSION: A better understanding of the pre-return-to-work consultation would improve collaboration and coordination of actions to facilitate resuming work and job retention for patients with LBP.

Interest of the Ergo-Kit(®) for the clinical practice of the occupational physician. A study of 149 patients recruited in a rehabilitation program.

OBJECTIVE: Functional capacity evaluation is commonly used to assess the abilities of patients to perform some tasks. Ergo-Kit(®) is a validated tool assessing both functional capacities of patients and workplace demands. The objective of this study was to evaluate the relevance of the Ergo-Kit(®) data for occupational physicians during the return-to-work process. METHODS: A retrospective and monocenter study was conducted on all patients included in a rehabilitation program and assessed with the Ergo-Kit(®) tool between 2005 and 2014. Workplace demands and patients' functional capacities were evaluated and confronted. Self-beliefs and perceived disability were also assessed and compared to the functional capacity evaluation. RESULTS: One hundred and forty-nine working-age patients (85 men, 64 women; 39±12 years) suffering from musculoskeletal disorders or other diseases were included. Main causes of mismatch between workplace demands and functional capacities were manual handling of loads, postures with arms away from the body and repetitive motions at work; sitting posture was correlated with a lesser physical workload; and Oswestry score was correlated with functional capacities evaluated by the Ergo-Kit(®). CONCLUSION: Ergo-Kit(®) is a relevant tool to assess the multidimensional aspects of workplace demands and functional capacities. It could be very helpful for occupational physicians to manage return-to-work.

Carpal tunnel syndrome and computer exposure at work in two large complementary cohorts.

OBJECTIVES: The boom in computer use and concurrent high rates in musculoskeletal complaints and carpal tunnel syndrome (CTS) among users have led to a controversy about a possible link. Most studies have used cross-sectional designs and shown no association. The present study used longitudinal data from two large complementary cohorts to evaluate a possible relationship between CTS and the performance of computer work. SETTINGS AND PARTICIPANTS: The Cosali cohort is a representative sample of a French working population that evaluated CTS using standardised clinical examinations and assessed self-reported computer use. The PrediCTS cohort study enrolled newly hired clerical, service and construction workers in several industries in the USA, evaluated CTS using symptoms and nerve conduction studies (NCS), and estimated exposures to computer work using a job exposure matrix. PRIMARY AND SECONDARY OUTCOME MEASURES: During a follow-up of 3-5 years, the association between new cases of CTS and computer work was calculated using logistic regression models adjusting for sex, age, obesity and relevant associated disorders. RESULTS: In the Cosali study, 1551 workers (41.8%) completed follow-up physical examinations; 36 (2.3%) participants were diagnosed with CTS. In the PrediCTS study, 711 workers (64.2%) completed follow-up evaluations, whereas 31 (4.3%) had new cases of CTS. The adjusted OR for the group with the highest exposure to computer use was 0.39 (0.17; 0.89) in the Cosali cohort and 0.16 (0.05; 0.59) in the PrediCTS cohort. CONCLUSIONS: Data from two large cohorts in two different countries showed no association between computer work and new cases of CTS among workers in diverse jobs with varying job exposures. CTS is far more common among workers in non-computer related jobs; prevention efforts and work-related compensation programmes should focus on workers performing forceful hand exertion.

Prevalence of thoracic spine pain in a surveillance network.

BACKGROUND: Back pain has long been identified as a major occupational health issue, but there are few prevalence studies on thoracic spine pain (TSP). The epidemiological surveillance of musculoskeletal disorders implemented in 2002 by the French Institute for Public Health Surveillance in the Pays de la Loire region provided the opportunity to study the prevalence of TSP in a large, representative sample of workers. AIMS: To assess the prevalence of TSP across a week in a regional workforce according to age, occupational category and industry sector in men and women separately. METHODS: A random sample of workers aged 20-59 years, representative of the regional workforce, was constituted between 2002 and 2005. Medical and occupational data were gathered by questionnaire. RESULTS: The sample consisted of 3710 workers (58% men). The prevalence of TSP was higher in women (17%) than in men (9%). Lower grade male white-collar workers were more likely to report TSP (17%) than male workers in other occupational categories, whereas upper grade female white-collar and professional workers were more likely to report TSP. No significant difference in the prevalence of TSP was noted in either men or women according to industry sector. CONCLUSIONS: Although TSP is less frequent than low back and neck pain, the results of this study indicate that 1 in 10 men and 1 in 5 women suffer from TSP.

Prevalence of knee bursitis in the workforce.

BACKGROUND: Knee bursitis (KB) is a common disorder in specific occupations requiring frequent and/or sustained kneeling postures. AIMS: To assess the prevalence of KB in the general working population. METHODS: Between 2002 and 2005, a total of 3710 workers of a French region were randomly included in the study. A standardized physical examination of the knee was performed when knee pain was reported by the worker during the preceding 12 months. The criteria for diagnosis of KB were (i) the presence of pain and/or tenderness in the anterior face of the knee at the date of the examination (or for at least 4 days in the preceding week) and (ii) the presence of swelling and/or pressure-induced pain of the pre- or infra-patellar bursa. Occupational risk factors were assessed by a self-administered questionnaire. RESULTS: The prevalence of uni- or bilateral cases of knee bursitis was low: 0.6% [0.2-0.9] in men and 0.2% [0.0-0.6] in women. The highest prevalence was observed in the construction sector (2.3% [0.8-5.4]) and in the food and meat processing industries (1.4% [0.4-3.5)]. More blue-collar workers were affected than other occupation categories (0.8% [0.3-1.2] versus 0.1% [0.0-0.4]). CONCLUSIONS: The study showed a concentration of cases among male workers exposed to heavy workloads and frequent kneeling.

Working in temporary employment and exposure to musculoskeletal constraints.

BACKGROUND: In recent years, temporary work (TW) has increased in European countries due to the greater uncertainty in the economy. AIMS: To compare the prevalence of non-specific musculoskeletal symptoms of the upper extremities (UEMSDs) and their main risk factors in blue-collar workers employed through temporary agencies (TW) and in those in permanent employment (PE). METHODS: UEMSDs occurring during the preceding 7 days were assessed using a Nordic questionnaire completed by 1493 blue-collar workers randomly included in a surveillance programme for UEMSDs (171 in TW and 1322 in PE) in a large French region. Personal factors and work-related risk factors for UEMSDs were assessed by self-administered questionnaires. RESULTS: The prevalence of UEMSDs during the preceding 7 days did not significantly differ between workers in TW or PE. However, after adjustment for age and gender, TW had a higher risk of symptoms of the wrist/hand region (OR = 1.6, 95% CI 1.04-2.6). TW was characterized by higher exposure to paced work (OR = 2.0, 95% CI 1.4-3.0), repetitive work (OR = 2.3, 95% CI 1.6-3.4), awkward postures of the wrist (OR = 1.6, 95% CI 1.2-2.4) and intensive use of vibrating hand tools (OR = 1.7, 95% CI 1.1-2.3). Workers in TW suffered from a lack of autonomy (OR = 2.5, 95% CI 1.7-3.6) and skill discretion at work (OR = 2.0, 95% CI 1.3-3.1) more frequently, but there was no difference in relation to psychological demands of the task or social support. CONCLUSIONS: Temporary workers were more frequently exposed to working time constraints, repetitive work and biomechanical constraints of the wrist/hand region when compared to permanent workers and may represent a subpopulation at particularly high risk of UEMSDs.

Stress perception among employees in a French University Hospital.

BACKGROUND: Nantes University Hospital comprises 20 activity sectors. AIMS: To investigate the role of the work environment at the individual level, as well as the workplace level, in explaining the variability in employees' perception of stress. METHODS: A self-administered enhanced Karasek Job Content Questionnaire was sent to employees. The main variables were the psychological job demand (PJD) score and the job decision latitude (JDL) score. Univariate and multivariate logistic regression analyses were conducted to estimate crude odds ratio (OR) and adjusted OR. RESULTS: One thousand eight hundred and sixty-eight workers were included. Nursing managers (25.9 ± 3.4), non-specialized nurses (25.6 ± 3.5) and physicians (25.3 ± 3.4) had the highest PJD. Cleaning staff (61.4 ± 11.4) and nurse aides (63.6 ± 8.8) had the lowest JDL. Items correlated with high PJD are: unacceptable work schedule, adjusted OR 2.16 (95% CI = 1.3-3.5); unsatisfactory workstation accessibility, OR 1.92 (95% CI = 1.1-3.2); getting from A to B, OR 1.67 (95% CI = 1.2-2.4); and heavy manual handling, OR 1.62 (95% CI = 1.1-2.3). Sleeping tablet use was linked to high PJD (P < 0.01), extra workload (P < 0.05) and tiredness (P < 0.05). Use of painkillers was correlated with musculoskeletal disorders (P < 0.05). CONCLUSIONS: Our study highlighted women >40 years old, nurse managers, physicians, permanent and/or full-time workers having a high PJD. Nursing aides, medical secretary and nurses presented with high strain. Better control measures should be implemented for those socioprofessional categories to improve prevention measures. This study should be repeated in the future with a multi-centre approach to determine the generalizability of the findings.

Return to work of 87 severely impaired low back pain patients two years after a program of intensive functional rehabilitation.

UNLABELLED: Return to work is the main long-term objective of rehabilitation programs for patients with chronic low back pain (LBP). OBJECTIVES: Evaluation of work status and number of sick leaves in 87 severely impaired LBP patients 2 years after a functional restoration program. PATIENTS AND METHODS: Open prospective study. POPULATION: 87 chronic LBP patients. INTERVENTION: multidisciplinary functional restoration program. Ergonomic advice on the workplace was performed for 53 patients. OUTCOME: work status and number of sick leaves due to LBP. RESULTS: The characteristics of the 26 patients lost to follow-up did not differ significantly from the rest of the population before the program. In the 61 remaining patients, 48 (78%) were at work at 2 years, 43 full-time and 22 at the same job. Nineteen worked in a different environment. Sick leaves were reduced by 60% compared to the 2 years prior to the program: 128 days (+/-200 days) versus 329 days (+/-179 days); p<0.005. CONCLUSION: Sick leaves remained significantly reduced and the number of workers who were at work significantly increased at 2 years after an intensive program.

[Symposium on the indications of surgery in chronic upper limb pain]. / Table ronde sur la place de la chirurgie dans les douleurs chroniques du membre supérieur.

Chronic pain is a true disease with neuromuscular and psychosocial features. It affects the individual as a whole. The consultation should not be limited to a physical approach and the clinician should not shelter behind useless investigations. It is necessary to listen to the patient, to seek elements of catastrophism and hypervigilance, to unmask a strategy of avoidance, and to evaluate the socioprofessional context. Psychosocial factors are the determinant ones in chronicisation of the pain and therefore are the ones that have to be addressed in the process of treatment and professional reintegration. The place of surgery is limited to the treatment of a trigger point (starting factor) and only when it is actually causing real symptoms and when surgical treatment will lead to regression of all the symptoms. On the whole though, the signs are never localised and we find a diffuse hypersensitivity with secondary dysfunction of the whole upper limb, functional exclusion, features of deconditioning, and all in an unfavourable psychosocial context. Thus, the assessment must be multidisciplinary and ideally the treatment should be managed in a centre of rehabilitation.

The French Musculoskeletal Disorders Surveillance Program: Pays de la Loire network.

OBJECTIVES: An epidemiological surveillance system for work-related musculoskeletal disorders (MSDs) was implemented in 2002 in France's Pays de la Loire region to assess the incidence and prevalence of MSDs in the general and working populations, identify levels of exposure to occupational risk factors and investigate the proportion of cases attributable to work exposure. METHODS: The program combines (1) surveillance of sentinel health events in the general population (carpal tunnel syndrome (CTS) was the sentinel event for upper limb MSDs), (2) assessment of the prevalence of the main upper limb MSDs and their risk factors in the workplace based on a network of occupational physicians and (3) registration of the notification of work-related diseases (WRDs). RESULTS: 1168 incident cases of CTS were included over a 3 year period. The estimated incidence of CTS was 1.00 per 1000 person-years in those aged 20-59 years (0.60 in men and 1.40 in women). The incidence rate was higher in employed than unemployed persons in the year of diagnosis (0.6 per 1000 vs 0.3 in men and 1.7 vs 0.8 in women). The occupational physician network noted high prevalence rates: 11% of men and 15% of women had at least one of the six main upper limb clinically-diagnosed MSDs. The WRD survey showed that MSDs represented 65% of notified WRDs. CONCLUSION: The Pays de la Loire program plays a significant role in informing the authorities and the public about the state of current MSDs. It is planned to extend it to a routine national surveillance program.

Management of low back pain in primary care prior to multidisciplinary functional restoration: a retrospective study of 72 patients.

OBJECTIVE: Chronic low back pain is a major socioeconomic health issue, due to the high direct (healthcare) and indirect (sick leave) costs. The aim of the present study was to describe the primary care management of low back pain patients prior to their inclusion in a multidisciplinary functional restoration network. METHODS: A descriptive, retrospective, questionnaire-based survey of the general practitioners dealing with 72 low back pain patients. RESULTS: Patients had been monitored by their general practitioner for an average of four years, with a mean frequency of eight appointments per year per patient. Ninety-three percent and 60% of the patients had been referred to a rheumatologist and a surgeon, respectively. Ninety-eight percent had had lumbar radiographies, 80% had undergone a computed tomography scan and 64% had undergone magnetic resonance imaging. The most commonly prescribed medications were anti-inflammatories and first- or second-line analgesics. Thirty percent had already received morphine analgesics and 50% had taken antidepressants. Thirty-two percent had undergone lumbar surgery. Physiotherapy was frequently reported and, indeed, 6% of patients had participated in over 100 sessions. Total sick leave averaged 8.25 months over the study's follow-up period. CONCLUSION: The time interval before referral to a multidisciplinary care team is long and so GPs should be encouraged and helped to organize this process earlier. It is also essential to determine factors which predict progression to chronic LBP.
