The effectiveness of graded activity for low back pain in occupational healthcare.

BACKGROUND: Low back pain is a common medical and social problem associated with disability and absence from work. Knowledge on effective return to work (RTW) interventions is scarce. OBJECTIVE: To determine the effectiveness of graded activity as part of a multistage RTW programme. DESIGN: Randomised controlled trial. SETTING: Occupational healthcare. SUBJECTS: 112 workers absent from work for more than eight weeks due to low back pain were randomised to either graded activity (n = 55) or usual care (n = 57). INTERVENTION: Graded activity, a physical exercise programme aimed at RTW based on operant-conditioning behavioural principles. MAIN OUTCOME MEASURES: The number of days off work until first RTW for more then 28 days, total number of days on sick leave during follow up, functional status, and severity of pain. Follow up was 26 weeks. RESULTS: Graded activity prolonged RTW. Median time until RTW was equal to the total number of days on sick leave and was 139 (IQR = 69) days in the graded activity group and 111 (IQR = 76) days in the usual care group (hazard ratio = 0.52, 95% CI 0.32 to 0.86). An interaction between a prior workplace intervention and graded activity, together with a delay in the start of the graded activity intervention, explained most of the delay in RTW (hazard ratio = 0.86, 95% CI 0.40 to 1.84 without prior intervention and 0.39, 95% CI 0.19 to 0.81 with prior intervention). Graded activity did not improve pain or functional status clinically significantly. CONCLUSIONS: Graded activity was not effective for any of the outcome measures. Different interventions combined can lead to a delay in RTW. Delay in referral to graded activity delays RTW. In implementing graded activity special attention should be paid to the structure and process of care.

Medical care of employees long-term sick listed due to mental health problems: a cohort study to describe and compare the care of the occupational physician and the general practitioner.

OBJECTIVES: To describe medical management by the general practitioner (GP) and occupational physician (OP) of workers sick listed due to mental health problems, and to determine agreement in diagnosis, main cause of sickness absence and obstacles in return to work. METHODS: A cohort of 555 employees being sick listed for 12 to 20 weeks due to mental health problems was recruited and followed for 1 year. These employees were interviewed about their mental health and contacts with GP, OP, other specialists and employer. In addition, the GP and/or the OP of 72 employees were interviewed about the medical diagnosis and management. RESULTS: Most employees sick listed for 12-20 weeks visited their GP and OP. According to the employees most interventions applied by the GP were medical interventions, such as referral of employees and prescription of medical drugs. Working conditions were seldom discussed by the GP and work-related interventions were never applied. Most interventions applied by the OP were work-related interventions and/or contact with the employer. The OP more often talked about working conditions and conflicts. According to the employees, the communication between GP and OP only took place in 8% of the cases. Agreement in the diagnosis, main cause of sickness absence, and obstacles in return to work reported by the GPs and OPs of the same employee was poor. In addition, similarity in reported diagnosis by GP and/or OP and the employees' scores on valid questionnaires on (mental) health was limited. CONCLUSIONS: The lack of communication and agreement by Dutch GPs and OPs in medical diagnosis and management of employees long-term sick listed due to mental health problems are indicators of sub-optimal medical treatment and return-to-work strategies.

[Limited change in the quality of the social medical guidance and in the satisfaction of sick-listed patients, after collaborative projects between general practitioners and occupational physicians].

OBJECTIVE: To evaluate whether regional projects for collaboration between general practitioners (GPs) and occupational physicians (OPs) improved the quality of their social medical guidance (SMG) and the satisfaction of their patients. DESIGN: Evaluation study with before and after measurements with respect to the same GPs and OPs. METHOD: Structured interviews were conducted with 58 GPs and 83 OPs regarding the SMG of their sick-listed patients. Before the project, the SMG of 1109 sick-listed patients was assessed and after the project, 1 or 1.5 years later, the SMG of 1121 sick-listed patients. These patients were sent a questionnaire by means of which their satisfaction could be assessed. RESULTS: After the projects, the quality ofthe diagnosis by the OPs was improved and they also more often adhered to the official guidelines of the KNMG (Royal Netherlands Medical Association) when contacting the GP about a patient. The GPs more often contacted the OP if they needed more information about a patient after reaching a diagnosis. Nevertheless, in half to three-quarters of the patients for whom contact between GPs and OPs was indicated, this contact did not take place. There was no significant increase in patient satisfaction. Before the projects, patients gave their GP a grade of 8.2 on a 10-point scale and after the projects this was 8.5; the OPs were given a grade of 7.5 both times. Further analysis showed that there was no significant relation between the quality ofthe SMG and the patient's satisfaction with the doctor. CONCLUSION: Although there was some improvement in the quality of the SMG, there was still insufficient cooperation between GPs and OPs compared to the guidelines. An increase in patient satisfaction was not demonstrated.

Return-to-work outcomes following work disability: stakeholder motivations, interests and concerns.

INTRODUCTION: Satisfaction with return-to-work (RTW) outcomes is dependent on many factors, including a clear exposition of what people define as a "good outcome" and the information they use to determine if such an outcome has been achieved. This paper defines the key stakeholders involved in the RTW process and discusses the need to understand their motivations, interests, and concerns. METHODS: A review of the literature and discussions with RTW researchers conducted by a multidisciplinary group of academic researchers. RESULTS: Our analysis suggests that RTW stakeholders can share the goal of a successful RTW; however, this consensus has to be viewed in light of other, sometimes competing, goals and the environments in which stakeholders operate. CONCLUSIONS: It is suggested that more clearly articulating and operationalizing stakeholders' perspectives will allow researchers to advance the understanding of RTW interventions and outcomes.

A developmental conceptualization of return to work.

INTRODUCTION: Although return to work (RTW) is a phenomenon that has been researched for many years, our ability to understand and improve outcomes is still limited. As an avenue for advancing the field, this paper presents an alternative way of thinking about RTW. METHOD: The conceptualization was constructed based on a review of the literature and the comments of RTW and workers' compensation researchers. RESULTS: RTW is presented as an evolving process, comprising four key phases: i.e., "off work," "work re-entry," "retention," and "advancement." In addition, multiple phase-specific outcomes that may be used to evaluate RTW success are advanced. CONCLUSION: Broadening thinking about RTW to take into consideration the complexities of its developmental nature holds promise for understanding and improving RTW, as it not only clarifies the importance of incremental milestones, but also facilitates intervention choice and evaluation.

Patient satisfaction with occupational health physicians, development of a questionnaire.

AIMS: To develop a questionnaire that measures specific aspects of patient satisfaction with occupational health physicians. METHODS: General patient satisfaction questionnaires, a literature survey, and interviews with patients were used. An initial questionnaire was distributed among sick listed patients (n = 432) of occupational physicians (n = 90) from different occupational health services. To reduce items and to develop scales exploratory factor analysis and reliability analysis was used. A linear regression model was used to predict satisfaction ratings from the scales of the questionnaire. RESULTS: Questions about independence of the occupational physician were difficult to ask unambiguously. The factor analysis revealed five relevant factors which were named "being taken seriously as a patient", "attitude towards occupational health services", "trust and confidentiality", "expectations", and "comfort and access". All scales could be reduced to a maximum of five items without reducing the scale reliability too much. In the regression analysis, 71% of the variance of satisfaction ratings was explained by the first four scales and most by the first scale. "Comfort and access" did not contribute significantly to the model. CONCLUSIONS: A short questionnaire was developed to measure different aspects of patient satisfaction specific for occupational health. Whether the questionnaire can effectively lead to quality improvement in occupational health services should be investigated.

The effectiveness of ergonomic interventions on return-to-work after low back pain; a prospective two year cohort study in six countries on low back pain patients sicklisted for 3-4 months.

AIMS: To study occurrence and effectiveness of ergonomic interventions on return-to-work applied for workers with low back pain (LBP). METHODS: A multinational cohort of 1631 workers fully sicklisted 3-4 months due to LBP (ICD-9 codes 721, 722, 724) was recruited from sickness benefit claimants databases in Denmark, Germany, Israel, Sweden, the Netherlands, and the United States. Medical, ergonomic, and other interventions, working status, and return-to-work were measured using questionnaires and interviews at three months, one and two years after the start of sickleave. Main outcome measure was time to return-to-work. Cox's proportional hazards model was used to calculate hazard ratios regarding the time to return-to-work, adjusted for prognostic factors. RESULTS: Ergonomic interventions varied considerably in occurrence between the national cohorts: 23.4% (mean) of the participants reported adaptation of the workplace, ranging from 15.0% to 30.5%. Adaptation of job tasks and adaptation of working hours was applied for 44.8% (range 41.0-59.2%) and 46.0% (range 19.9-62.9%) of the participants, respectively. Adaptation of the workplace was effective on return-to-work rate with an adjusted hazard ratio (HR) of 1.47 (95% CI 1.25 to 1.72; p < 0.0001). Adaptation of job tasks and adaptation of working hours were effective on return-to-work after a period of more than 200 days of sickleave with an adjusted HR of 1.78 (95% CI 1.42 to 2.23; p < 0.0001) and 1.41 (95% CI 1.13 to 1.76; p = 0.002), respectively. CONCLUSIONS: Results suggest that ergonomic interventions are effective on return-to-work of workers long term sicklisted due to LBP.

Participatory ergonomics as a return-to-work intervention: a future challenge?

BACKGROUND: Participatory ergonomics (PE) are often applied for prevention of low back pain (LBP). In this pilot-study, a PE-program is applied to the disability management of workers sick listed due to LBP. METHODS: The process, implementation, satisfaction, and barriers for implementation concerning the PE-program were analyzed quantitatively and qualitatively for 35 workers sick listed 2-6 weeks due to LBP and their ergonomists. RESULTS: Two-hundred-and-seventy ergonomic solutions were proposed to the employer. They were targeted more at work design and organization of work (58.9%) than at workplace and equipment design (38.9%). They were planned mostly on a short-term basis (74.8%). Almost half (48.9%) of the solutions for work adjustment were completely or partially implemented within 3 months after the first day of absenteeism. Most workers were satisfied about the PE-program (median score 7.8 on a 10-point scale) and reported a stimulating effect on return-to-work (66.7%). Main obstacles to implementation were technical or organizational difficulties (50.0%) and physical disabilities of the worker (44.8%). CONCLUSIONS: This study suggests that compliance, acceptance, and satisfaction related to the PE-program were good for all participants. Almost half of the proposed solutions were implemented.

Ineffective disability management by doctors is an obstacle for return-to-work: a cohort study on low back pain patients sicklisted for 3-4 months.

AIMS: To determine obstacles for return-to-work in disability management of low back pain patients sicklisted for 3-4 months. METHODS: A cohort of 467 low back pain patients sicklisted for 3-4 months was recruited. A questionnaire was sent to their occupational physicians (OPs) concerning the medical management, obstacles to return-to-work, and the communication with treating physicians. RESULTS: The OPs of 300 of 467 patients participated in this study. In many cases OPs regarded the clinical waiting period (43%), duration of treatment (41%), and view (25%) of the treating physicians as obstacles for return-to-work. Psychosocial obstacles for return-to-work such as mental blocks, a lack of job motivation, personal problems, and conflicts at work were all mentioned much less frequently by OPs. In only 19% of the patients was there communication between OP and treating physician. Communication almost always entailed an exchange of information, and less frequently an attempt to harmonise the management policy. Surprisingly communication was also limited, when OPs felt that the waiting period (32%), duration of treatment (30%), and view (28%) of treating physicians inhibited return-to-work. Communication was significantly associated with the following obstacles for return-to-work: passivity with regard to return-to-work and clinical waiting period; adjusted odds ratios were 3.35 and 2.23, respectively. CONCLUSIONS: Medical management of treating physicians is often an obstacle for return to work regarding low back pain patients sicklisted for 3-4 months, in the opinion of OPs. Nevertheless communication between OPs and the treating physicians in disability management of these patients is limited. More attention to prevention of absenteeism and bilateral communication is needed in medical courses.

[Little communication between company doctors and private physicians with respect to hindrances to return to work after prolonged absence from work because of low back pain].

OBJECTIVE: To determine occurrence and reasons of contact between company doctors and treating physicians with respect to patients absent with low back pain for three months. DESIGN: Prospective cohort study. METHOD: A cohort of employees who were absent for 3 months with back pain were selected according to defined criteria. A questionnaire about medical status and communication with treating physicians was sent to their company doctors. RESULTS: The company doctors of 300 of 467 employees participated. In 19% of the employees the company doctor contacted the curative sector (56 contacts had taken place, 14 were planned). The contact consisted almost always of exchange of information and less frequently of co-operation towards a mutual policy. In almost 50% of the cases the company doctors regarded the clinical waiting period, length of treatment and opinion of the curative sector as disincentives to return to work. Psychosocial factors such as psychological problems, work-related motivation, private problems and a conflict between employer and employee all were mentioned less frequently. Although contacts were slightly more frequent when psychosocial factors, treatment or opinion of the curative sector inhibited return to work, only disincentives such as work-related motivation, motivation to return to work and the waiting period were significantly associated with the contact frequency. CONCLUSION: The communication rate between company doctors and the curative sector in employees long absent with back pain is low. Communication consists of exchange of information rather than co-operation towards a mutual policy. Although according to many company doctors the curative sector plays an inhibitive role in return to work, they do not communicate accordingly.

Cardiovascular autonomic function in multiple sclerosis.

In this study blood pressure (BP) and heart rate (HR) responses to standing and HR responses to deep breathing were assessed in 34 patients with clinically definite multiple sclerosis (MS) and 63 healthy subjects. Normal ranges, which were clearly age related for both HR responses, were obtained. The BP response to standing was abnormal in 13% of the MS patients, these patients demonstrating significant postural hypotension. The HR response to standing was abnormal in 28% of the MS patients, with a normal initial increase in heart rate and a significantly reduced reflex bradycardia. On deep breathing 36% of MS patients showed abnormal HR changes. The resting HR did not differ between both groups. Abnormalities of one or more tests were found in 53% of the MS patients. No relationship was found between abnormal cardiovascular autonomic responses and the symptoms, duration, severity and progression of the disease. Based on clinical and magnetic resonance imaging findings no indications were found for localisation of the autonomic disturbances in the brainstem. It is suggested that at least a part of the cardiovascular autonomic lesions in MS is located outside the brainstem, i.e. in supramedullary reflex pathways or in the spinal cord.

Quantitative measurement of vibratory sense and temperature sense in patients with multiple sclerosis.

In this study the vibratory perception threshold (VPT) and the thermal discrimination threshold (TDT) were measured in 33 patients with clinically definite multiple sclerosis (MS). VPT values were abnormal in a majority of MS patients (68%). There was no relation between VPT and the severity of the disease. TDT values were elevated less frequently (30%); abnormal TDTs were found only in patients with severe disease. It is suggested that this can be explained by MS-plaques having predilection sites within the central nervous system and by differences in functional and morphological properties of sensory pathways. Quantitative measurements of VPT and TDT seem to be suitable techniques for the detection of minor sensory signs of central origin.
