To examine the efficacy of a participatory ergonomics intervention in preventing musculoskeletal disorders among kitchen workers. Participatory ergonomics is commonly recommended to reduce musculoskeletal disorders, but evidence for its effectiveness is sparse.
                A cluster randomised controlled trial among the 504 workers of 119 kitchens in Finland was conducted during 2002-2005. Kitchens were randomised to an intervention (n = 59) and control (n = 60) group. The duration of the intervention that guided the workers to identify strenuous work tasks and to seek solutions for decreasing physical and mental workload, was 11 to 14 months. In total, 402 ergonomic changes were implemented. The main outcome measures were the occurrence of and trouble caused by musculoskeletal pain in seven anatomical sites, local fatigue after work, and sick leave due to musculoskeletal disorders. Individual level data were collected by a questionnaire at baseline and every 3 months during the intervention and 1-year follow-up period. All response rates exceeded 92%.
                No systematic differences in any outcome variable were found between the intervention and control groups during the intervention or during the 1-year follow-up.
                The intervention did not reduce perceived physical work load and no evidence was found for the efficacy of the intervention in preventing musculoskeletal disorders among kitchen workers. It may be that a more comprehensive redesign of work organisation and processes is needed, taking more account of workers' physical and mental resources. Sickness absenteeism caused by musculoskeletal disorders (MSDs) is a persistent and costly occupational health challenge. In a prospective controlled trial, we compared the effects on sickness absenteeism of a more proactive role for insurance case managers as well as workplace ergonomic interventions with that of traditional case management. Patients with physician-diagnosed MSDs were randomized either to the intervention group or the reference group offered the traditional case management routines. Participants filled out a comprehensive questionnaire at the initiation of the study and after 6 months. In addition, administrative data were collected at 0.6, and 12 months after the initiation of the project. For the entire 12-month period, the total mean number of sick days for the intervention group was 144.9 (SEM 11.8) days/person as compared to 197.9 (14.0) days in the reference group (P < 0.01). Compared with the reference group, employees in the intervention group significantly more often received a complete rehabilitation investigation (84% versus 27%). The time for doing this was reduced by half (59.4 (5.2) days versus 126.8 (19.2), P < .01). The odds ratio for returning to work in the intervention group was 2.5 (95% confidence interval 1.2-5.1) as compared with the reference group. The direct cost savings were USD 1195 per case, yielding a direct benefit-to-cost ratio of 6.8. It is suggested that the management of MSDs should to a greater degree focus on early return to work and building on functional capacity and employee ability. Allowing the case managers a more active role as well as involving an ergonomist in workplace adaptation meetings might also be beneficial. The purpose of this study was to evaluate the effectiveness of an activating intervention designed to reduce sick leave duration in patients with emotional distress or minor mental disorders.
                In a 1.5-year randomized controlled trial, 194 patients with minor mental disorders received either an experimental intervention by social workers or general practitioners' usual care. The intervention focused on understanding causes, developing and implementing problem-solving strategies and promoting early work resumption. Outcome measures were sick leave duration, mental health and physical health (questionnaires included the Hospital Anxiety and Depression Scale, the Four-Dimensional Symptom Questionnaire and SF-36), all measured at baseline at and 3, 6 and 18 months later. Multilevel analyses were used to evaluate differences between groups.
                The groups did not differ significantly on any of the outcome measures, except that the experimental group reported higher satisfaction with treatment.
                Although the intervention has benefits, it was not successful at its primary goal (i.e., to reduce sick leave duration in patients with emotional distress or minor mental disorders). Programs aimed at the reduction of sick leave duration may yield better results if targeted at patients with more severe emotional problems than at those with exclusively emotional distress or minor mental disorders, or if delivered by caregivers who are closer to the work environment than are social workers, such as occupational physicians. Mental health problems often affect functioning to such an extent that they result in sick leave. The worldwide reported prevalence of mental health problems in the working population is 10%-18%. In developed countries, mental health problems are one of the main grounds for receiving disability benefits. In up to 90% of cases the cause is stress-related, and health-care utilisation is mainly restricted to primary care. The aim of this study was to assess the effectiveness of our Minimal Intervention for Stress-related mental disorders with Sick leave (MISS) in primary care, which is intended to reduce sick leave and prevent chronicity of symptoms.
                Cluster-randomised controlled educational trial.
                Primary health-care practices in the Amsterdam area, The Netherlands.
                A total of 433 patients (MISS n = 227, usual care [UC] n = 206) with sick leave and self-reported elevated level of distress.
                Forty-six primary care physicians were randomised to either receive training in the MISS or to provide UC. Eligible patients were screened by mail.
                The primary outcome measure was duration of sick leave until lasting full return to work. The secondary outcomes were levels of self-reported distress, depression, anxiety, and somatisation.
                No superior effect of the MISS was found on duration of sick leave (hazard ratio 1.06, 95% confidence interval 0.87-1.29) nor on severity of self-reported symptoms.
                We found no evidence that the MISS is more effective than UC in our study sample of distressed patients. Continuing research should focus on the potential beneficial effects of the MISS; we need to investigate which elements of the intervention might be useful and which elements should be adjusted to make the MISS effective. To evaluate the effectiveness of a participatory workplace intervention compared with usual care for sick-listed employees with distress, with regard to return to work (RTW) within the 12-month follow-up.
                Employees with distress and sick-listed for 2-8 weeks were randomised to a workplace intervention (n=73) or to usual care (n=72). The participatory workplace intervention is a stepwise process involving the sick-listed employee and their supervisor, aimed at reducing obstacles for RTW by reaching consensus about an action plan for RTW. Outcome variables were lasting RTW, cumulative sickness absence and stress-related symptoms.
                Overall, an HR of 0.99 (95% CI 0.70 to 1.39) indicated no effect of the workplace intervention on lasting RTW. However, the workplace intervention significantly reduced the time until lasting RTW for employees who at baseline intended to return to work despite symptoms with an HR of 2.05 (95% CI 1.22 to 3.45). Employees who intended to return to work despite symptoms returned to work after 55 days in the workplace intervention group and 120 days in the usual care group. No such effect of the intervention was found for employees without baseline intentions to return to work despite symptoms (HR=0.78, 95% CI 0.47 to 1.28).
                No overall effect of the participatory workplace intervention on lasting RTW was found. The workplace intervention appeared effective on lasting RTW for employees who at baseline intended to return to work despite symptoms. For employees who showed no baseline intention to return to work, the intervention did not have any effect. Other approaches are needed for this subgroup. This trial has been registered at the Dutch National Trial Register ISRCTN92307123. Physical inactivity and obesity are major public health problems. Our objective was to investigate the effectiveness of an individual counseling intervention at the workplace on physical activity fitness and health. Counseling content derived from the Patient-centered Assessment and Counseling for Exercise and Nutrition (PACE) program.
                A total of 299 employees of three municipal services in the Dutch town of Enschede were randomly allocated into intervention (n =131) and control group (n =168). Over a 9-month period, intervention group subjects were offered seven counseling sessions. Counseling was based on the individual's stage of behavioral change using PACE physical activity and nutrition protocols. Subjects in both the intervention and control group received written information about several lifestyle factors. Primary outcome measures were physical activity (total energy expenditure, during sports activities, during physical activity leisure time other than sports, and meeting the moderate-intensity public health recommendations); cardiorespiratory fitness; and prevalence of musculoskeletal symptoms. Secondary outcome measures were body composition (body mass index [BMI], and percentage of body fat measured via skinfold thicknesses); blood pressure; and blood cholesterol.
                There were significant positive effects on total energy expenditure, physical activity during sports, cardiorespiratory fitness, percentage of body fat, and blood cholesterol. No effects were found for the proportion of subjects meeting the public health recommendation of moderate-intensity physical activity, physical activity during leisure time other than sports, prevalence of musculoskeletal symptoms, body mass index, and blood pressure.
                Individual face-to-face counseling at the workplace based on PACE protocols positively influenced physical activity levels and some components of physical fitness. The implementation of workplace counseling programs for individuals should therefore be promoted. An integrated case management (ICM) approach (ergonomic and problem-solving intervention) to work-related upper-extremity disorders was examined in relation to patient satisfaction, future symptom severity, function, and return to work (RTW). Federal workers with work-related upper-extremity disorder workers' compensation claims (n = 205) were randomly assigned to usual care or ICM intervention. Patient satisfaction was assessed after the 4-month intervention period. Questionnaires on clinical outcomes and ergonomic exposure were administered at baseline and at 6- and 12-months postintervention. Time from intervention to RTW was obtained from an administrative database. ICM group assignment was significantly associated with greater patient satisfaction. Regression analyses found higher patient satisfaction levels predicted decreased symptom severity and functional limitations at 6 months and a shorter RTW. At 12 months, predictors of positive outcomes included male gender, lower distress, lower levels of reported ergonomic exposure, and receipt of ICM. Findings highlight the utility of targeting workplace ergonomic and problem solving skills. To evaluate the effectiveness of guideline-based care (GBC) of workers with mental health problems, which promotes counseling by the occupational physician (OP) facilitating return to work (RTW).
                In a randomized controlled trial with police workers on sick leave due to mental health problems (n = 240), trained OPs delivered GBC in the intervention group. Time to RTW and recurrences during 1-year follow-up, analyzed using Cox proportional hazards models, were compared with usual care (UC) with easy access to a psychologist.
                GBC by OPs did not result in earlier RTW than UC. Subgroup analysis showed a small effect in favor of GBC for workers with administrative functions and/or "minor" stress-related symptoms.
                GBC did not differ in RTW compared with UC, but may be beneficial for the majority of workers with minor stress-related disorders. Newly diagnosed mild Type 2 diabetic patients, aged 30-55 years, were included in the prospective, multi-centre Diabetes Intervention Study. They were randomly allotted to either an intervention group receiving intensified health education or to a control group on usual care. This paper reports the incidence, duration of and causes for absence from work due to any disease in the patients who were working during the first 5-year follow-up. Data from 817 patients could be taken into account. 14.5% of the intervention patients and 17.3% of the control patients had never been on the sick list. Those patients who had undergone intensified health education were listed sick less often. Women showed a higher work absenteeism in either group; they had higher blood pressure and higher body mass index at entry. Cardiovascular diseases and musculo-skeletal disorders were major reasons for absence from work. However, when compared to the general population, these Type 2-diabetic patients were approximately four times more often on the sick list. Thus, the health education programme of the Diabetes Intervention Study was shown to be effective with respect to work absenteeism. Teaching patients is recommended as an important part of the therapeutic regimen. Work-related stress is widespread and can lead to long-term absenteeism and work disability. Cognitive-behavioral treatment (CBT) has demonstrated effectiveness in treating psychopathology but has only rarely been tested in clinical samples with work-related stress. A randomized controlled trial was conducted to investigate the efficacy of CBT-based stress management training (SMT). Eighty-two patients on sickness leave with work-related stress were randomly assigned to (a) individual SMT, (b) group SMT, or (c) care as usual (CAU). The SMT comprised 12 sessions conducted by a psychologist. Complaints of burnout and distress were measured at baseline, and at 4, 7, and 10 months. Absenteeism was measured during the whole research period. Across treatment conditions, complaints and sickness absence reduced considerably between baseline and 4 months. Thereafter, complaints remained approximately stable, whereas sickness absence further reduced. Hardly any significant group difference emerged, and no consistent pattern could be discerned in favor of any treatment condition. In subgroups with low depressive complaints, though, individual SMT resulted in larger reductions of some complaints than CAU. In conclusion, this study adds to the evidence that CBT-based interventions as currently practiced are not successful in treating patients with clinical levels of work-related stress.

The government wants to reduce inequalities through policies based on evidence, the health of childbearing women and their babies being priority areas for action. National Service Frameworks (NSFs) are being set up to ensure high quality services for all groups. The External Working Group looking into maternity services for the Children's NSF seeks evidence upon which to plan strategies for all women, while focusing attention on the most disadvantaged. Wide differentials are noted between high- and low-income groups in the outcomes of pregnancy and the health of babies. The worst outcomes appear to be concentrated in small subgroups of disadvantaged women.
                To report on a review of studies of interventions improving perinatal outcomes for disadvantaged women, to inform policy and practice around the organization and delivery of statutory services in the UK.
                We searched six relevant databases for reviews, intervention studies, audits and descriptions of services reporting outcomes for disadvantaged groups of women, published between 1990 and 2003. Synthesis was performed around what works and what does not work. Gaps in the evidence base were identified.
                We found limited evidence of effective and promising interventions for childbearing women from minority ethnic groups, women experiencing domestic violence, women with mental health illness and HIV infected women. Few studies were well-designed or powered to detect effectiveness. There were no studies of interventions for women prisoners, homeless women and travellers.
                Searching for intervention studies primarily by participant subgroup has brought in evidence from few well-designed studies on which to plan policy. Combining this approach with searching for intervention studies addressing behaviour like smoking, and needs like social support, may provide further evidence to tackle inequalities in the perinatal period.
As a result of the few available studies, no convincing conclusions can be formulated about the effectiveness of workplace interventions on work-related outcomes and health outcomes regardless of the type of work disability. The pooled data for the musculoskeletal disorders subgroup indicated that workplace interventions are effective in the reduction of sickness absence, but they are not effective in improving health outcomes. The evidence from the subgroup analysis on musculoskeletal disorders was rated as moderate-quality evidence. Unfortunately, conclusions cannot be drawn on the effectiveness of these interventions for mental health problems and other health conditions due to a lack of studies.
