Adapting shift work schedules for sleep quality, sleep duration, and sleepiness in shift workers.

BACKGROUND: Shift work is associated with insufficient sleep, which can compromise worker alertness with ultimate effects on occupational health and safety. Adapting shift work schedules may reduce adverse occupational outcomes. OBJECTIVES: To assess the effects of shift schedule adaptation on sleep quality, sleep duration, and sleepiness among shift workers. SEARCH METHODS: We searched CENTRAL, PubMed, Embase, and eight other databases on 13 December 2020, and again on 20 April 2022, applying no language restrictions. SELECTION CRITERIA: We included randomised controlled trials (RCTs) and non-RCTs, including controlled before-after (CBA) trials, interrupted time series, and cross-over trials. Eligible trials evaluated any of the following shift schedule components. • Permanency of shifts • Regularity of shift changes • Direction of shift rotation • Speed of rotation • Shift duration • Timing of start of shifts • Distribution of shift schedule • Time off between shifts • Split shifts • Protected sleep • Worker participation We included studies that assessed sleep quality off-shift, sleep duration off-shift, or sleepiness during shifts. DATA COLLECTION AND ANALYSIS: Two review authors independently screened the titles and abstracts of the records recovered by the search, read through the full-text articles of potentially eligible studies, and extracted data. We assessed the risk of bias of included studies using the Cochrane risk of bias tool, with specific additional domains for non-randomised and cluster-randomised studies. For all stages, we resolved any disagreements by consulting a third review author. We presented the results by study design and combined clinically homogeneous studies in meta-analyses using random-effects models. We assessed the certainty of the evidence with GRADE. MAIN RESULTS: We included 11 studies with a total of 2125 participants. One study was conducted in a laboratory setting and was not considered for drawing conclusions on intervention effects. The included studies investigated different and often multiple changes to shift schedule, and were heterogeneous with respect to outcome measurement. Forward versus backward rotation Three CBA trials (561 participants) investigated the effects of forward rotation versus backward rotation. Only one CBA trial provided sufficient data for the quantitative analysis; it provided very low-certainty evidence that forward rotation compared with backward rotation did not affect sleep quality measured with the Basic Nordic Sleep Questionnaire (BNSQ; mean difference (MD) -0.20 points, 95% confidence interval (CI) -2.28 to 1.89; 62 participants) or sleep duration off-shift (MD -0.21 hours, 95% CI -3.29 to 2.88; 62 participants). However, there was also very low-certainty evidence that forward rotation reduced sleepiness during shifts measured with the BNSQ (MD -1.24 points, 95% CI -2.24 to -0.24; 62 participants). Faster versus slower rotation Two CBA trials and one non-randomised cross-over trial (341 participants) evaluated faster versus slower shift rotation. We were able to meta-analyse data from two studies. There was low-certainty evidence of no difference in sleep quality off-shift (standardised mean difference (SMD) -0.01, 95% CI -0.26 to 0.23) and very low-certainty evidence that faster shift rotation reduced sleep duration off-shift (SMD -0.26, 95% CI -0.51 to -0.01; 2 studies, 282 participants). The SMD for sleep duration translated to an MD of 0.38 hours' less sleep per day (95% CI -0.74 to -0.01). One study provided very low-certainty evidence that faster rotations decreased sleepiness during shifts measured with the BNSQ (MD -1.24 points, 95% CI -2.24 to -0.24; 62 participants). Limited shift duration (16 hours) versus unlimited shift duration Two RCTs (760 participants) evaluated 80-hour workweeks with maximum daily shift duration of 16 hours versus workweeks without any daily shift duration limits. There was low-certainty evidence that the 16-hour limit increased sleep duration off-shift (SMD 0.50, 95% CI 0.21 to 0.78; which translated to an MD of 0.73 hours' more sleep per day, 95% CI 0.30 to 1.13; 2 RCTs, 760 participants) and moderate-certainty evidence that the 16-hour limit reduced sleepiness during shifts, measured with the Karolinska Sleepiness Scale (SMD -0.29, 95% CI -0.44 to -0.14; which translated to an MD of 0.37 fewer points, 95% CI -0.55 to -0.17; 2 RCTs, 716 participants). Shorter versus longer shifts One RCT, one CBA trial, and one non-randomised cross-over trial (692 participants) evaluated shorter shift duration (eight to 10 hours) versus longer shift duration (two to three hours longer). There was very low-certainty evidence of no difference in sleep quality (SMD -0.23, 95% CI -0.61 to 0.15; which translated to an MD of 0.13 points lower on a scale of 1 to 5; 2 studies, 111 participants) or sleep duration off-shift (SMD 0.18, 95% CI -0.17 to 0.54; which translated to an MD of 0.26 hours' less sleep per day; 2 studies, 121 participants). The RCT and the non-randomised cross-over study found that shorter shifts reduced sleepiness during shifts, while the CBA study found no effect on sleepiness. More compressed versus more spread out shift schedules One RCT and one CBA trial (346 participants) evaluated more compressed versus more spread out shift schedules. The CBA trial provided very low-certainty evidence of no difference between the groups in sleep quality off-shift (MD 0.31 points, 95% CI -0.53 to 1.15) and sleep duration off-shift (MD 0.52 hours, 95% CI -0.52 to 1.56). AUTHORS' CONCLUSIONS: Forward and faster rotation may reduce sleepiness during shifts, and may make no difference to sleep quality, but the evidence is very uncertain. Very low-certainty evidence indicated that sleep duration off-shift decreases with faster rotation. Low-certainty evidence indicated that on-duty workweeks with shift duration limited to 16 hours increases sleep duration, with moderate-certainty evidence for minimal reductions in sleepiness. Changes in shift duration and compression of workweeks had no effect on sleep or sleepiness, but the evidence was of very low-certainty. No evidence is available for other shift schedule changes. There is a need for more high-quality studies (preferably RCTs) for all shift schedule interventions to draw conclusions on the effects of shift schedule adaptations on sleep and sleepiness in shift workers.

Education and training for preventing sharps injuries and splash exposures in healthcare workers.

BACKGROUND: In healthcare settings, health care workers (HCWs) are at risk of acquiring infectious diseases through sharps injuries and splash exposures to blood or bodily fluids. Education and training interventions are widely used to protect workers' health and safety and to prevent sharps injuries. In certain countries, they are part of obligatory professional development for HCWs. OBJECTIVES: To assess the effects of education and training interventions compared to no intervention or alternative interventions for preventing sharps injuries and splash exposures in HCWs. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, NHSEED, Science Citation Index Expanded, CINAHL and OSH-update (from all time until February 2016). In addition, we searched the databases of Global Health, AustHealth and Web of Science (from all time until February 2016). The original search strategy was re-run in November 2019, and again in February 2020. In April 2020, the search strategy was updated and run in CINAHL, MEDLINE, Scopus and Web of Science (from 2016 to current). SELECTION CRITERIA: We considered randomized controlled trials (RCTs), cluster-randomized trials (cluster-RCTs), controlled clinical trials (CCTs), interrupted time series (ITS) study designs, and controlled before-and-after studies (CBA), that evaluated the effect of education and training interventions on the incidence of sharps injuries and splash exposures compared to no-intervention. DATA COLLECTION AND ANALYSIS: Two authors (SC, HL) independently selected studies, and extracted data for the included studies. Studies were analyzed, risk of bias assessed (HL, JL) , and pooled using random-effect meta-analysis, where applicable, according to their design types. As primary outcome we looked for sharps injuries and splash exposures and calculated them as incidence of injuries per 1000 health care workers per year. For the quality of evidence we applied GRADE for the main outcomes. MAIN RESULTS: Seven studies met our inclusion criteria: one cluster-RCT, three CCTs, and three ITS studies. The baseline rates of sharps injuries varied from 43 to 203 injuries per 1000 HCWs per year in studies with hospital registry systems. In questionnaire-based studies, the rates of sharps injuries were higher, from 1800 to 7000 injuries per 1000 HCWs per year.  The majority of studies utilised a combination of education and training interventions, including interactive demonstrations, educational presentations, web-based information systems, and marketing tools which we found similar enough to be combined. In the only cluster-RCT (n=796) from a high-income country, the single session educational workshop decreased sharps injuries at 12 months follow-up, but this was not statistically significant either measured as registry-based reporting of injuries (RR 0.46, 95% CI 0.16 to 1.30, low-quality evidence) or as self-reported injuries (RR 0.41, 95% CI 0.14 to 1.21, very low-quality evidence) In three CCTs educational interventions decreased sharps injuries at two months follow-up (RR 0.68, 95% CI 0.48 to 0.95, 330 participants, very low-quality evidence). In the meta-analysis of two ITS studies with a similar injury rate, (N=2104), the injury rate decreased immediately post-intervention by 9.3 injuries per 1000 HCWs per year (95% CI -14.9 to -3.8). There was a small non-significant decrease in trend over time post-intervention of 2.3 injuries per 1000 HCWs per year (95% CI -12.4 to 7.8, low-quality evidence). One ITS study (n=255) had a seven-fold higher injury rate compared to the other two ITS studies and only three data points before and after the intervention. The study reported a change in injury rate of 77 injuries per 1000 HCWs (95% CI -117.2 to -37.1, very low-quality evidence) immediately after the intervention, and a decrease in trend post-intervention of 32.5 injuries per 1000 HCWs per year (95% CI -49.6 to -15.4, very low quality evidence). None of the studies allowed analyses of splash exposures separately from sharps injuries. None of the studies reported rates of blood-borne infections in patients or staff. There was very low-quality evidence of short-term positive changes in process outcomes such as knowledge in sharps injuries and behaviors related to injury prevention.  AUTHORS' CONCLUSIONS: We found low- to very low-quality evidence that education and training interventions may cause small decreases in the incidence of sharps injuries two to twelve months after the intervention. There was very low-quality evidence that educational interventions may improve knowledge and behaviors related to sharps injuries in the short term but we are uncertain of this effect. Future studies should focus on developing valid measures of sharps injuries for reliable monitoring. Developing educational interventions in high-risk settings is another priority.

Work disability negotiations between supervisors and occupational health services: factors that support supervisors in work disability management.

PURPOSE: A work disability negotiation takes place between a supervisor, the disabled employee and the occupational health service (OHS) to support the disabled employee in returning to their work, often with temporary work accommodation. The objective of this study was to define the factors of a work disability negotiation with OHS that supported or hindered supervisors in their task/role in work disability management. METHODS: The study setting comprised two parts: the creation of survey questions and the actual survey of supervisors (N = 254) from six public and private organizations in Finland. Of these, 133 (52%) had participated in one or more work disability negotiations. The responses covered about 240 work disability cases and considerably more negotiations. RESULTS: The study identified four key elements that the supervisors expressed as major success factors in the negotiations. First, it was crucial that the supervisors learned about the employee's health restrictions and understood the issues relating to their work disability. Second, the parties should aim for common solutions and conclusions through collaboration. Third, active participation of all the negotiation parties is important. The supervisors gave a high rating to OHS taking their views seriously. Last, the supervisors appreciated collaboration in a constructive atmosphere. CONCLUSION: In order for a negotiation to help supervisors in their challenges, it should reach solutions, conclusions and a restructured comprehension of the work disability problem in a constructive atmosphere and with active communication between stakeholders.

Musculoskeletal Symptoms Among Finnish Professional Orchestra Musicians.

BACKGROUND: The prevalence of musculoskeletal symptoms is high among professional musicians (73-88%). AIMS: We investigated the prevalence of musculoskeletal symptoms in Finnish symphony orchestra musicians. We compared individual instruments as well as the perceived demands of orchestral programs and difficulties in recovering after performances. METHODS: In this cross-sectional questionnaire 920 of 2,785 members of the Finnish Musicians' Union (33%) completed the questionnaire, including 361 full-time members of symphony orchestras. Questions about pain symptoms and frequency were based on the national survey done in 2011. RESULTS: Among the 361 full-time orchestra musicians, those playing all instruments experienced frequent pain, both in the last 30 days and exceeding 30 days in the last 12 months, in their neck or upper extremities. Female musicians experienced significantly more neck (69%), elbow (31%), and wrist (30%) pain than males (neck 52%, elbow 23%, wrist 19%). The profiles varied according to the different instruments and their playing positions. Musculoskeletal symptoms correlated with perceived demand of the orchestral program and difficulties in recovering after performances. Professional musicians experienced nearly twice as often neck pain in the last 30 days (female musicians 69%, male musicians 52%) than persons of the same age in the Finnish working population (female 41%, male 27%). CONCLUSION: Symphony orchestra musicians experience nearly twice as much musculoskeletal symptoms of the neck and upper extremities as others their age. To prevent musicians' playing-related problems, special emphasis should be focused on recovery after concerts, including the special demands of different composers and the frequency of rehearsals and performances.

Person-directed, non-pharmacological interventions for sleepiness at work and sleep disturbances caused by shift work.

BACKGROUND: Shift work is often associated with sleepiness and sleep disorders. Person-directed, non-pharmacological interventions may positively influence the impact of shift work on sleep, thereby improving workers' well-being, safety, and health. OBJECTIVES: To assess the effects of person-directed, non-pharmacological interventions for reducing sleepiness at work and improving the length and quality of sleep between shifts for shift workers. SEARCH METHODS: We searched CENTRAL, MEDLINE Ovid, Embase, Web of Knowledge, ProQuest, PsycINFO, OpenGrey, and OSH-UPDATE from inception to August 2015. We also screened reference lists and conference proceedings and searched the World Health Organization (WHO) Trial register. We contacted experts to obtain unpublished data. SELECTION CRITERIA: Randomised controlled trials (RCTs) (including cross-over designs) that investigated the effect of any person-directed, non-pharmacological intervention on sleepiness on-shift or sleep length and sleep quality off-shift in shift workers who also work nights. DATA COLLECTION AND ANALYSIS: At least two authors screened titles and abstracts for relevant studies, extracted data, and assessed risk of bias. We contacted authors to obtain missing information. We conducted meta-analyses when pooling of studies was possible. MAIN RESULTS: We included 17 relevant trials (with 556 review-relevant participants) which we categorised into three types of interventions: (1) various exposures to bright light (n = 10); (2) various opportunities for napping (n = 4); and (3) other interventions, such as physical exercise or sleep education (n = 3). In most instances, the studies were too heterogeneous to pool. Most of the comparisons yielded low to very low quality evidence. Only one comparison provided moderate quality evidence. Overall, the included studies' results were inconclusive. We present the results regarding sleepiness below. Bright light Combining two comparable studies (with 184 participants altogether) that investigated the effect of bright light during the night on sleepiness during a shift, revealed a mean reduction 0.83 score points of sleepiness (measured via the Stanford Sleepiness Scale (SSS) (95% confidence interval (CI) -1.3 to -0.36, very low quality evidence). Another trial did not find a significant difference in overall sleepiness on another sleepiness scale (16 participants, low quality evidence).Bright light during the night plus sunglasses at dawn did not significantly influence sleepiness compared to normal light (1 study, 17 participants, assessment via reaction time, very low quality evidence).Bright light during the day shift did not significantly reduce sleepiness during the day compared to normal light (1 trial, 61 participants, subjective assessment, low quality evidence) or compared to normal light plus placebo capsule (1 trial, 12 participants, assessment via reaction time, very low quality evidence). Napping during the night shiftA meta-analysis on a single nap opportunity and the effect on the mean reaction time as a surrogate for sleepiness, resulted in a 11.87 ms reduction (95% CI 31.94 to -8.2, very low quality evidence). Two other studies also reported statistically non-significant decreases in reaction time (1 study seven participants; 1 study 49 participants, very low quality evidence).A two-nap opportunity resulted in a statistically non-significant increase of sleepiness (subjective assessment) in one study (mean difference (MD) 2.32, 95% CI -24.74 to 29.38, 1 study, 15 participants, low quality evidence). Other interventionsPhysical exercise and sleep education interventions showed promise, but sufficient data to draw conclusions are lacking. AUTHORS' CONCLUSIONS: Given the methodological diversity of the included studies, in terms of interventions, settings, and assessment tools, their limited reporting and the very low to low quality of the evidence they present, it is not possible to determine whether shift workers' sleepiness can be reduced or if their sleep length or quality can be improved with these interventions.We need better and adequately powered RCTs of the effect of bright light, and naps, either on their own or together and other non-pharmacological interventions that also consider shift workers' chronobiology on the investigated sleep parameters.

Pharmacological interventions for sleepiness and sleep disturbances caused by shift work.

CLINICAL QUESTION: Are pharmacological interventions associated with better-quality sleep and alertness in shift workers? BOTTOM LINE: Low-quality evidence shows that melatonin is associated with 24 minutes longer daytime sleep after the shift but not with faster falling asleep compared with placebo. There is no association between hypnotics, such as zopiclone, and sleep outcomes, alertness, or harms. The alertness-promoting medications armodafinil and modafinil are associated with improved alertness during shift work but are also associated with headache and nausea.

Pharmacological interventions for sleepiness and sleep disturbances caused by shift work.

BACKGROUND: Shift work results in sleep-wake disturbances, which cause sleepiness during night shifts and reduce sleep length and quality in daytime sleep after the night shift. In its serious form it is also called shift work sleep disorder. Various pharmacological products are used to ameliorate symptoms of sleepiness or poor sleep length and quality. OBJECTIVES: To evaluate the effects of pharmacological interventions to reduce sleepiness or to improve alertness at work and decrease sleep disturbances whilst off work, or both, in workers undertaking shift work in their present job and to assess their cost-effectiveness. SEARCH METHODS: We searched CENTRAL, MEDLINE, EMBASE, PubMed and PsycINFO up to 20 September 2013 and ClinicalTrials.gov up to July 2013. We also screened reference lists of included trials and relevant reviews. SELECTION CRITERIA: We included all eligible randomised controlled trials (RCTs), including cross-over RCTs, of pharmacological products among workers who were engaged in shift work (including night shifts) in their present jobs and who may or may not have had sleep problems. Primary outcomes were sleep length and sleep quality while off work, alertness and sleepiness, or fatigue at work. DATA COLLECTION AND ANALYSIS: Two authors independently selected studies, extracted data and assessed risk of bias in included trials. We performed meta-analyses where appropriate. MAIN RESULTS: We included 15 randomised placebo-controlled trials with 718 participants. Nine trials evaluated the effect of melatonin and two the effect of hypnotics for improving sleep problems. One trial assessed the effect of modafinil, two of armodafinil and one examined caffeine plus naps to decrease sleepiness or to increase alertness.Melatonin (1 to 10 mg) after the night shift may increase sleep length during daytime sleep (mean difference (MD) 24 minutes, 95% confidence interval (CI) 9.8 to 38.9; seven trials, 263 participants, low quality evidence) and night-time sleep (MD 17 minutes, 95% CI 3.71 to 30.22; three trials, 234 participants, low quality evidence) compared to placebo. We did not find a dose-response effect. Melatonin may lead to similar sleep latency times as placebo (MD 0.37minutes, 95% CI - 1.55 to 2.29; five trials, 74 participants, low quality evidence).Hypnotic medication, zopiclone, did not result in significantly longer daytime sleep length compared to placebo in one low quality trial and we could not use the data from the study on lormetazepam.Armodafinil taken before the night shift probably reduces sleepiness by one point on the Karolinska Sleepiness Scale (KSS) (MD -0.99, 95% CI -1.32 to -0.67; range 1 to 10; two trials, 572 participants, moderate quality evidence) and increases alertness by 50 ms in a simple reaction time test (MD -50.0, 95% CI -85.5 to -15.5) at three months' follow-up in shift work sleep disorder patients. Modafinil probably has similar effects on sleepiness (KSS) (MD -0.90, 95% CI -1.45 to -0.35; one trial, 183 participants, moderate quality evidence) and alertness in the psychomotor vigilance test in the same patient group. Post-marketing, severe skin reactions have been reported. Adverse effects reported by trial participants were headache, nausea and a rise in blood pressure. There were no trials in non-patient shift workers.Based on one trial, caffeine plus pre-shift naps taken before the night shift decreased sleepiness (KSS) (MD -0.63, 95% CI -1.09 to -0.17).We judged most trials to have a low risk of bias even though the randomisation method and allocation concealment were often not described. AUTHORS' CONCLUSIONS: There is low quality evidence that melatonin improves sleep length after a night shift but not other sleep quality parameters. Both modafinil and armodafinil increase alertness and reduce sleepiness to some extent in employees who suffer from shift work sleep disorder but they are associated with adverse events. Caffeine plus naps reduces sleepiness during the night shift, but the quality of evidence is low. Based on one low quality trial, hypnotics did not improve sleep length and quality after a night shift.We need more and better quality trials on the beneficial and adverse effects and costs of all pharmacological agents that induce sleep or promote alertness in shift workers both with and without a diagnosis of shift work sleep disorder. We also need systematic reviews of their adverse effects.

Exercise intervention and health checks for middle-aged men with elevated cardiovascular risk: a randomized controlled trial.

OBJECTIVE: To study the effects of a health check by a nurse alone or combined with an exercise intervention in middle-aged men at increased cardiovascular risk. DESIGN: A randomized controlled trial. SETTING AND INTERVENTION: Primary care in Kirkkonummi municipality with 36 000 inhabitants. A health check by a nurse alone or combined with an exercise intervention to controls with no intervention was compared. SUBJECTS: A total of 168 men aged 35 to 45 years with at least two cardiovascular risk factors and physical activity (PA) frequency < 3 times a week. MAIN OUTCOME MEASURES: Metabolic syndrome (MetS) as defined by International Diabetes Federation/American Heart Association and self-reported PA frequency. RESULTS: Overall, focusing on health increased physical activity frequency in middle-aged men. After one year, 19% had increased PA to ≥ 3 times a week (95% CI 12-26). All study groups increased PA to ≥ 3 times: 26% of men in the exercise intervention group, 15% of men in the health check group, and 16% of controls. The differences between the groups were not statistically significant. The intervention did not have any meaningful impact on MetS or other cardiovascular outcomes at one-year follow up. CONCLUSIONS: Physical activity increased in all study groups of middle-aged men in this health-promotion trial. The interventions had no effect on metabolic syndrome or other cardiovascular outcomes in the participants. The trial increased awareness and collaboration in physical activity promotion among municipal health care and exercise services.

Work ability meetings - Challenges and Resolutions, a survey to Finnish occupational physicians.

BACKGROUND: Work ability meetings (WAM) are an essential and common tool of disability management in occupational health services in Finland. Meetings are held between an employee, a supervisor, and an occupational physician (OP). The aim is mainly to support work ability. OBJECTIVES: To describe challenges and resolutions in the meetings as described by OPs. METHODS: An internet survey was emailed to the members (n = 1304) of the Finnish Society of Occupational Health Physicians in August 2014. We asked physicians to describe those WAMs they had attended, especially challenges and resolutions concerning WAM. RESULTS: A total of 302 (23%) OPs responded to the survey. Most severe of the challenges were personal conflicts and a lack of confidence between the parties at the workplace. Also, the participants' views may differ about the purpose and goal of the meeting. The respondents noted that the employer might be unable to organize modified work for disabled employees. As a resolution, OPs need to prepare well and maintain their professional and neutral role in WAMs in all cases. OPs also mentioned the need for training in insurance medicine and rehabilitation as well as skills as a mediator. CONCLUSIONS: WAM is a potential tool for return to work and disability management in collaboration between employees, employers, and occupational health when all the participants reach a common goal and become aware of their role in the process. OPs need to recognize possible conflicting interests and contact each party before WAM. Keeping confidentiality in WAMs is a crucial matter.

Musculoskeletal pain at multiple sites and its effects on work ability in a general working population.

OBJECTIVES: Musculoskeletal pain often occurs at multiple sites concurrently. The aim of this study was to examine the associations between multi-site pain and self-rated work ability and retirement plans among actively working people. METHODS: The Health 2000 Survey was carried among a representative sample of Finnish adults. Musculoskeletal pain during the preceding month in the lower back, neck or shoulders, upper extremities, hips and lower extremities, and work ability and intentions to retire early were assessed. Subjects were also clinically examined. Analyses were restricted to 30-64-year-old subjects actively working during the preceding 12 months who provided information on work ability outcomes (population-weighted number of subjects=4087). Log-binomial regression was used to estimate prevalence ratios of reduced work ability. RESULTS: Single-site pain was reported by 33% of subjects, 20%, 9% and 4% reported pain in two, three and four sites, respectively, and 8%-15% reported poor work ability. Every fifth person had thought about retiring early. Age- and gender-adjusted risks of poor physical work ability and own prognosis of poor future work ability increased from 2 for single-site pain to 8 for pain at four sites. Risks remained considerably elevated after adjustment for various covariates, including clinical musculoskeletal disorders and functional capacity. Poor current work ability was most affected by multi-site pain at older age (50-64 years) and intentions to retire early at age 40-49 years. CONCLUSIONS: Co-occurring pain is a considerable threat to work ability. Workers with multi-site pain may benefit from targeted preventive measures to sustain their work ability. Future studies should also consider multi-site pain as an important risk factor for reduced work ability.

[Judgment of the level of evidence and strength of recommendations in healthcare according to the GRADE working group]. / Hoitosuositusten näytönasteen ja vahvuuden arviointi GRADE-työryhmän tapaan.

Finnish doctors are pioneers in the production and utilization of evidence-based recommendations in healthcare. Doctor's databases were established by the end of the 1980s and Current Care guidelines have been devised since 1994. In evidence-based recommendations it is essential to provide the user with a description of the quality of research data used as the basis for the recommendation. Consistent, applicable and transparent methods are helpful in the judgment of the quality of studies and strength of evidence. In this article we describe the judgment of the level of evidence and the strength of recommendations according to the international GRADE working group.

Work disability negotiations: supervisors' view of work disability and collaboration with occupational health services.

Purpose: To introduce the Finnish practice of collaboration aiming to enhance work participation, to ask supervisors about its reasons and usefulness, to study supervisors' needs when they face work disability, and to compare the experiences of supervisors whose profiles differ. Materials and methods: An online questionnaire based on the Finnish practice of collaboration between supervisor and occupational health services (OHS) went to supervisors in six public and private organizations. A total of 254 supervisors responded, of whom, 133 (52%) had collaborated in work disability negotiations, representing a wide variety with differing professional profiles. Results: In their role of managing work disability, supervisors appeared to benefit from three factors: an explicit company disability management (DM) policy, supervisors' training in DM, and collaboration with OHS. Reasons for work disability negotiations were long or repeated sick-leaves and reduced work performance. Expectations for occupational health consultations focused on finding vocational solutions and on obtaining information. Supervisors assessed the outcomes of collaboration as both vocational and medical. Supervisors with differing professional profiles prioritized slightly different aspects in collaboration. Conclusions: Collaboration with OHS is an important option for supervisors to enhance work modifications and the work participation of employees with work disability. Implications for Rehabilitation Work disability negotiation between supervisor, employee, and occupational health services (OHS) is an effective method to enhance work participation. Collaboration with occupational health can advance work modifications and also lead to medical procedures to improve work performance. Supervisor training, companies' explicit disability management policy, and collaboration with OHSs all advance employee's work participation. Collaboration with OHSs may serve as training for supervisors in their responsibility to support work participation.

Work-related stress management between workplace and occupational health care.

BACKGROUND: Work-related stress has been evaluated as one of the most important health risks in Europe. Prevention of work related stress and interventions to reduce risk factors for stress in the workplace are conducted together by the enterprise and occupational health services. OBJECTIVE: The aim of the study was to examine the experiences of Finnish occupational physicians on the stress management with enterprises. METHODS: From the Finnish Association of Occupational Health Physicians membership list 207 physicians responded to self-administered anonymous questionnaire. The data were analysed using SPSS 17.0. RESULTS: The client enterprises contacted occupational health services frequently about work-related stress. Collaboration between occupational health and enterprises was strongest in companies' own occupational health services and generally with most experienced physicians. Occupational health services and enterprises shared responsibility for managing work-related stress. CONCLUSIONS: Professional experience and close contact with organisation management favours successful stress management between occupational health and enterprises.

One trial assessed the effect of modafinil, two of armodafinil and one examined caffeine plus naps to decrease sleepiness or to increase alertness.

Finnish occupational health nurses' view of work-related stress: a cross-sectional study.

Occupational stress at work has been increasingly recognized as a major risk factor for chronic disease and poor quality of work life among employees. The purpose of this study was to examine how occupational health nurses in Finland manage work-related stress. A descriptive cross-sectional study design was used with a sample of 354 Finnish occupational nurses who responded to the survey. No specific standardized tools to assess or handle work-related stress in occupational health services or their client companies were identified. Open-ended interviews together with burnout questionnaires were the most frequently used methods to assess the stress of employees. Interventions were directed at individual employees. A need for standardized stress assessment instruments and stress management by work organizations was found. Methods to cope with work-related stress should be developed by the occupational health team and companies' health resources departments to ensure the adoption of common protocols.

Work-related stress management by Finnish enterprises.

Work-related stress has become one of the major problems in working societies and it increases employees' risk of disease. Its importance has been emphasized also due to its' great socio-economic consequences. Different stress management and worksite interventions have been implemented, however, the actual practices in companies have been assessed little. The purpose of this study was to examine how enterprises in Finland manage work-related stress. An assessment of work-related stress methods was conducted in 40 enterprises acting in the metropolitan area of Finland in May 2010 by a questionnaire. The concept of work-related stress was well known by participants. Enterprises rarely had their own work-related stress management protocol even though all of the workplaces had experienced work-related stress at some point. The collaboration between the workplace and occupational health services varied. Companies easily placed the responsibility for work-related stress assessment and handling on occupational health services. Workplaces have to pay more attention to work-related stress and related issues. The easiest way to do this is to collaborate with occupational health services. Protocols for collaboration should be developed jointly using the available models which have been established as cost-effective.

Pharmacological interventions for sleepiness and sleep disturbances caused by shift work

BACKGROUND: Shift work results in sleep-wake disturbances, which cause sleepiness during night shifts and reduce sleep length and quality in daytime sleep after the night shift. In its serious form it is also called shift work sleep disorder. Various pharmacological products are used to ameliorate symptoms of sleepiness or poor sleep length and quality. OBJECTIVES: To evaluate the effects of pharmacological interventions to reduce sleepiness or to improve alertness at work and decrease sleep disturbances whilst of work, or both, in workers undertaking shift work. METHODS: Search methods: We searched CENTRAL, MEDLINE, EMBASE, PubMed and PsycINFO up to 20 September 2013 and ClinicalTrials.gov up to July 2013. We also screened reference lists of included trials and relevant reviews. Selection criteria: We included all eligible randomised controlled trials (RCTs), including cross-over RCTs, of pharmacological products among workers who were engaged in shift work (including night shifts) in their present jobs and who may or may not have had sleep problems. Primary outcomes were sleep length and sleep quality while of work, alertness and sleepiness, or fatigue at work. Data collection and analysis: Two authors independently selected studies, extracted data and assessed risk of bias in included trials. We performed meta-analyses where appropriate. ...

Leadership, job well-being, and health effects--a systematic review and a meta-analysis.

OBJECTIVE: The aim of this systematic literature analysis was to study the association between leadership and well-being at work and work-related health. These intermediate outcomes are supposed to predict work-related loss of productivity and disability at work. METHODS: Original articles published in 1970 to 2005 were searched in MEDLINE and PsycINFO databases in a systematic manner. The main search terms were leadership, job satisfaction, well-being, sick leave, and disability pension. Out of 303 references, 93 publications were retrieved. In addition, other sources produced 69 articles. The strength of evidence was evaluated comprehensively. Altogether, 109 articles were thoroughly analyzed; our conclusions are based on 27 articles providing the best evidence. RESULTS: There was moderate evidence that leadership is associated with job well-being (risk ratio [RR] 1.40, range 1.36 to 1.57), sick leave (RR 0.73, range 0.70 to 0.89), and disability pension (RR 0.46, range 0.42 to 0.59). The evidence was weak on that leadership is associated with job satisfaction (median RR 2.23, range 1.30 to 3.51) but not with job performance (RR 1.13, range 0.55 to 1.20). CONCLUSIONS: There is a relative lack of well-founded prospective studies targeting the association between leadership and employee health, but the few available good studies suggest an important role of leadership on employee job satisfaction, job well-being, sickness absences, and disability pensions. The relationship between leadership and job performance remains unclear.
