Background GPs can find their role as issuers of sickness certification problematic, particularly in trying to maintain a balance between certifying absence and preserving the doctor–patient relationship. Little research has been published on consultations in which sickness absence has been certified. Aim To explore negotiations between GPs and patients in sickness absence certification, including how occupational health training may affect this process. Method A qualitative study was undertaken with GPs trained in occupational health who also participate in a UKwide surveillance scheme studying work-related ill-health. Telephone interviews were conducted with 31 GPs who had reported cases with associated sickness absence. Results Work-related sickness absence and patients' requests for a ‘sick note’ vary by diagnosis. Some GPs felt their role as patient advocate was of utmost importance, and issue certificates on a patient’s request, whereas others offer more resistance through a greater understanding of issues surrounding work and health aquired through occupational health training. GPs felt that their training helped them to challenge beliefs about absence from work being beneficial to patients experiencing ill-health; they felt better equipped to consider patients’ fitness for work, and issued fewer certificates as a result of this. Conclusion Complex issues surround GPs' role in the sickness-certification process, particularly when determining the patient's ability to work while maintaining a healthy doctor–patient relationship. This study demonstrates the potential impact of occupational health training for GPs, particularly in light of changes to the medical statement introduced in 2010. PMID:20883621

Objective The primary objective was to investigate how physicians’ gender and level of experience affects the rate and length of sick-leave certificate prescription. The secondary objective was to study the physicians’ gender and professional experience in relation to the diagnoses on the certificates. Design Retrospective, cross-sectional study of computerized medical records from 24 health care centres in 2005. Setting Primary care in Sweden. Subjects Primary care physicians (n = 589) and patients (n = 88 780) aged 18–64 years. Main outcome measures Rate and duration of sick leave certified by different categories of physicians and for different diagnoses and gender of patients. Results Sick leave was certified in 9.0% (musculoskeletal (3%) and psychiatric (2.3%) diagnoses were most common) of all contacts and the mean duration was 32.2 days. Overall there was no difference between male and female physicians in the sick-leave certification prescription rate (9.1% vs. 9.0%) or duration of sick leave (32.1 vs. 32.6 days). The duration of sick leave was associated with the physician's level of professional experience in general practice (GPs (Distriktläkare) 37, GP trainees (ST-läkare) 26, interns (AT-läkare) 20 and locum (vikarier) 19 days, p < 0.001). Conclusion Contrary to earlier studies we found no difference in sick-leave certification prescription rate and length between male and female physicians. PMID:22348513

Aim To report the types and duration of sickness certification for different common mental disorders (CMDs) and the prevalence of GP advice aimed at returning the patient to work. In the United Kingdom, common mental health problems, such and depression and stress, have become the main reasons for patients requesting a sickness certificate to abstain from usual employment. Increasing attention is being paid to mental health and its impact on employability and work capacity in all parts of the welfare system. However, relatively little is known about the extent to which different mental health diagnoses impact upon sickness certification outcomes, and how the GP has used the new fit note (introduced in 2010) to support a return to work for patients with mental health diagnoses. Sickness certification data was collected from 68 UK-based general practices for a period of 12 months. Findings The study found a large part of all sickness absence certified by GPs was due to CMDs (29% of all sickness absence episodes). Females, younger patients and those living in deprived areas were more likely to receive a fit note for a CMD (compared with one for a physical health problem). The highest proportion of CMD fit notes were issued for 'stress'. However, sickness certification for depression contributed nearly half of all weeks certified for mental health problems. Only 7% of CMD fit notes included any 'may be fit' advice from the GP, with type of advice varying by mental health diagnostic category. Patients living in the most socially deprived neighbourhoods were less likely to receive 'may be fit' advice on their CMD fit notes.

The study aimed to explore the views of general practitioners (GPs), nurses and physiotherapists towards extending the role of sickness certification beyond the medical profession in primary care. Fifteen GPs, seven nurses and six physiotherapists were selected to achieve varied respondent characteristics including sex, geographical location, service duration and post-graduate specialist training. Constant-comparative qualitative analysis of data from 28 semi-structured telephone interviews was undertaken. The majority of respondents supported the extended role concept; however members of each professional group also rejected the notion. Respondents employed four different legitimacy claims to justify their views and define their occupational boundaries in relation to sickness certification practice. Condition-specific legitimacy, the ability to adopt a holistic approach to sickness certification, system efficiency and control-related arguments were used to different degrees by each occupation. Practical suggestions for the extension of the sickness certification role beyond the medical profession are underpinned by the sociological theory of professional identity. Extending the authority to certify sickness absence beyond the medical profession is not simply a matter of addressing practical and organisational obstacles. There is also a need to consider the impact on, and preferences of, the specific occupations and their respective boundary claims. This paper explores the implications of extending the sick certification role beyond general practice. We conclude that the main policy challenge of such a move is to a) persuade GPs to relinquish this role (or to share it with other professions), and b) to understand the 'boundary work' involved.

Söderberg, Elsy; Müssener, Ulrika

2008-01-01

Background: Social insurance offices (SIOs) handle a wide range of complex assessments of the entitlement to sickness benefits for an increasing number of clients on sick leave and consequently, the demands on the SIOs have increased considerably. Aim: To gain deeper knowledge of the problems experienced by the SIOs in their work associated with entitlement to sickness benefits. Method: A descriptive and explorative qualitative approach was used to analyse data from two focus-group interviews, including six participants in each group. Results: The participants discussed different dilemmas in regard to; physicians’ responsibility for issuing sickness certificates, interactions with the insured individuals, disclosure of decisions, communications with medical consultants, documentation of sickness benefit claims, threats in the workplace, as well as their own competence. The SIOs regarded incomplete information on sickness certificates as a main problem, because they frequently had to contact the client and the physicians who issued the certificates in order to obtain further details, leading to delays in the decision-making whether to grant sickness benefits. Conclusions: More knowledge regarding SIOs work is required to improve the methods used in the sickness insurance system and to ensure adequate training of new staff members. PMID:21572827

The aims of this study were to determine and evaluate simultaneously the importance of factors known to influence sick-leave certification such as the sick leave-related diagnoses, the patients' socio-economic status, and characteristics of the physicians. Computerised medical records from 24 public primary health-care centres (PHCC) were used in a multilevel logistic regression analysis at three levels: patients (n=64,354; sex, age, socio-economic status, workplace factors and diagnoses), physicians (n=574; sex and level of experience) and PHCC (n=24). The variation of sick-leave certification at each level was the outcome. Most of the variation was attributed to the patient level and only 3.5% to the physician and 1.2% to the PHCC levels. Among the patient characteristics, psychiatric diagnoses (mostly acute stress) had the highest odds ratio (OR) for sick leave (OR=16.0; 95% confidence interval [CI] 15-17.2), followed by musculoskeletal diagnoses (OR=6.1; 95% CI 5.8-6.5). Other factors with increased OR were low education (OR=1.7; 95% CI 1.6-1.8), use of social allowance (OR=1.4; 95% CI 1.2-1.7) and certain workplaces (manufacture and health and social care). Being older was not associated with increased certified sick leave. The greatest variation in sick-leave certification rate was seen at the patient level, specifically psychiatric diagnoses. Socio-economic factors increasing the risk for sick-leave certification were education, social allowance and occupations in manufacture and caregiving. Understanding the impact of the different factors that influence certified sick leave is important both for targeted interventions in order to facilitate patients' return to work. © 2015 the Nordic Societies of Public Health.

Objective To explore whether frequency and duration of sick-leave certification for acute airway infections differ between general practitioners (GPs) in Poland and Norway. Design Cross-sectional survey. Setting Educational courses for GPs. Intervention We used a questionnaire with four vignettes presenting patients with symptoms consistent with pneumonia, sinusitis, common cold, and exacerbation of chronic obstructive pulmonary disease (COPD), respectively. For each vignette GPs were asked whether they would offer a sick-leave note, and if so, for how many days. Subjects Convenience samples of GPs in Poland (n = 216) and Norway (n = 171). Main outcome measures Proportion of GPs offering a sick-leave certificate. Duration of sick-leave certification. Results In Poland 100%, 95%, 87%, and 94% of GPs would offer sick leave for pneumonia, sinusitis, common cold, and exacerbation of COPD, respectively. Corresponding figures in Norway were 97%, 83%, 60%, and 90%. Regression analysis adjusting for the GPs' sex, speciality, experience, and workload indicated that relative risks for offering sick leave (Poland versus Norway) were 1.16 (95% CI 1.07–1.26) for sinusitis and 1.50 (1.28–1.75) for common cold. Among GPs who offered sick leave for pneumonia, sinusitis, common cold, and exacerbation of COPD, mean duration was 8.9, 7.5, 5.1, and 6.9 days (Poland) versus 6.6, 4.3, 3.1, and 6.1 days (Norway), respectively. In regression analyses the differences between the Polish and Norwegian samples in duration of sick leave were statistically significant for all vignettes. A pattern of offering sick leave for three, five, seven, 10, or 14 days was observed in both countries. Conclusion In the Polish sample GPs were more likely to offer sick-leave notes for sinusitis and common cold. GPs in Poland offered sick leaves of longer duration for pneumonia, sinusitis, common colds, and exacerbation of COPD compared with GPs in the Norwegian sample. PMID:21323635

System for analysing sickness absenteeism in Poland.

PubMed

Indulski, J A; Szubert, Z

1997-01-01

The National System of Sickness Absenteeism Statistics has been functioning in Poland since 1977, as the part of the national health statistics. The system is based on a 15-percent random sample of copies of certificates of temporary incapacity for work issued by all health care units and authorised private medical practitioners. A certificate of temporary incapacity for work is received by every insured employee who is compelled to stop working due to sickness, accident, or due to the necessity to care for a sick member of his/her family. The certificate is required on the first day of sickness. Analyses of disease- and accident-related sickness absenteeism carried out each year in Poland within the statistical system lead to the main conclusions: 1. Diseases of the musculoskeletal and peripheral nervous systems accounting, when combined, for 1/3 of the total sickness absenteeism, are a major health problem of the working population in Poland. During the past five years, incapacity for work caused by these diseases in males increased 2.5 times. 2. Circulatory diseases, and arterial hypertension and ischaemic heart disease in particular (41% and 27% of sickness days, respectively), create an essential health problem among males at productive age, especially, in the 40 and older age group. Absenteeism due to these diseases has increased in males more than two times.

The paper addresses the problem of sick leave in the hotel industry. It was hypothesized that there would be a tendency for granted sick leaves to include weekends, thus imposing an additional financial burden on the hotel in question. A total of 401 medical certificates from a large city hotel were reviewed. According to these certificates one third of the patients regained their health between Sunday and Monday. Of the patients with "short" sick leaves (less than a fortnight), 40% recovered between Sunday and Monday. The average duration of the sick leave for this group was 1.3 days longer than that of the patients whose sick leaves ended on other days of the week. The results are discussed in terms of the ambiguous position of the medical practitioner.

General practitioners (GPs) report sickness absence certification as challenging. They express need for support with functional assessment beyond guidelines and reforms. Case-specific collegial one-to-one guidance for other clinical topics has proved popular with GPs and may be an acceptable and effective way to improve GPs skills and competence in sickness absence certification. To present a new model of case-specific colleague guidance focusing on the management of long-term sickness absence and to describe its feasibility in terms of application and reception among GPs, and also GPs' self-reports of effects on their practice. Randomly selected GPs received case-specific collegial guidance over a 12-month period, in two Norwegian trials, delivered by former GPs employed by the social security administration. We measured reception and perceived effects by GPs' self-report and registered participation and withdrawal rates. The participation rate (n = 165) was 94%, and no GPs withdrew during training. Among the 116 GPs responding to the survey (70%), 112 (97%; 95% CI 92-99) stated they would recommend it to their colleagues. Considerable benefit from the guidance was reported by 68 (59%; 95% CI 50-68). The GPs self-reported other effects on their sickness absence certification, specifically an increased use of part-time sickness absence (Fit-Note equivalent). This model of case-specific colleague guidance to aid GPs' management of long-term sickness absence is feasible and was popular. This type of guidance was perceived by GPs to be somewhat beneficial and to alter their sickness absence certification behaviour, though the true impact requires further testing in controlled trials. © The Author 2017.

[Work ability and gender--physicians' assessment of sick-listed patients].

Medical assessments might be influenced by the patient's gender and work situation. This article explorers the relationship between physicians' assessments of work ability in sick-listed patients, and gender of the sick-listed and the physicians. We conducted a questionnaire survey among 52 primary care physicians and 442 of their sick-listed full-time employed patients in Aust-Agder county. The relationship between physician assessment of the patients' work ability and gender were analysed by full/part-time sick-leave, new/extended sick-leave, patient's workload, and the physician's gender. Multivariate analyses were done in two-level logistic regression models. 60% of sick-listed women were assessed as having "very much" or "much" reduced work ability, against 71% of sick-listed men (p < 0.01). Women received part-time sickness certification more often than men, 27% vs. 11% (p < 0.001). These relationships were only found for extended sick-leaves, and were significant also after adjustment for physician's gender and patient work-load. Male physicians assessed work ability as more reduced among sick-listed men than among sick-listed women. Primary care physicians assessed work ability as less reduced among women than men. Women more often received part-time sickness certification. Possibly, the physicians' gender influenced their assessment of work ability, but this should be confirmed by more studies.

Spatial task performance, sex differences, and motion sickness susceptibility.

There are substantial individual differences in susceptibility to motion sickness, yet little is known about what mediates these differences. Spatial ability and sex have been suggested as possible factors in this relationship. 89 participants (57 women) were administered a Motion Sickness Questionnaire that assesses motion sickness susceptibility, a Water-level Task that gauges sensitivity to gravitational upright, and a Mental Rotation Task that tests an individual's awareness of how objects typically move in space. Significant sex differences were observed in performance of both the Water-level Task (p<.01), and the Mental Rotation Task (p<.005), with women performing less accurately than men. Women also had significantly higher scores on the Motion Sickness Questionnaire (p<.005). Among men, but not women, significant negative relationships were observed between Water-level Task performance and Motion Sickness Questionnaire score (p<.001) and between Mental Rotation Task performance and Motion Sickness Questionnaire score (p<.005). In conclusion, women performed significantly more poorly than men did on the spatial ability tasks and reported significantly more bouts of motion sickness. In addition, men showed a significant negative relationship between spatial ability and motion sickness susceptibility.

Sickness certification implies that a health problem impairs ability to work. However, its assessment is seldom performed by physicians. Our objective was, therefore, to assess the specific influence of functional and environmental limitations on the length of sick-leave prescriptions. We conducted a cross-sectional study in French general teaching practices and recorded 353 initial sick-leave certifications. For each of them, the functional and environmental limitations were collected using the ATCIF questionnaire, derived from the International Classification of Functioning. Data analysis was based on a linear regression multivariate model. Among the functional limitations, "pain" was the main body function impairment (22% of impairments) and "mobility" the main activity limitation (48%). An environmental barrier was identified in 39% of sick-listed patients, mainly relating to "products and technology" (20%), which refers to workplace factors. The prescription was longer in cases of activity limitations relating to "mobility" and in cases of environmental barriers relating to "products and technology". The multivariate model explained 27% of the variability of sick-leave length through diagnosis elements and only 7% through functional and contextual elements. In sick-leave prescription, a functional and contextual approach, in addition to the traditional diagnosis-based approach, could better support patients' shared understanding and follow-up, and accountability towards health authorities. Implication for Rehabilitation Although sickness certification implies that a health problem impairs ability to work, decision on sick-leave length in general practice is primarily based on diagnosis. A more functional and contextual approach could better support patients' and other health professionals' shared understanding and follow-up, and accountability towards health authorities. Such evolution requires a change of paradigm in medical education, and the way of reasoning of healthcare professionals.

Health problems and disability in long-term sickness absence: ICF coding of medical certificates.

Morgell, Roland; Backlund, Lars G; Arrelöv, Britt; Strender, Lars-Erik; Nilsson, Gunnar H

2011-11-11

The purpose of this study was to test the feasibility of International Classification of Functioning, Disability and Health (ICF) and to explore the distribution, including gender differences, of health problems and disabilities as reflected in long-term sickness absence certificates. A total of 433 patients with long sick-listing periods, 267 women and 166 men, were included in the study. All certificates exceeding 28 days of sick-listing sent to the local office of the Swedish Social Insurance Administration of a municipality in the Stockholm area were collected during four weeks in 2004-2005. ICD-10 medical diagnosis codes in the certificates were retrieved and free text information on disabilities in body function, body structure or activity and participation were coded according to ICF short version. In 89.8% of the certificates there were descriptions of disabilities that readily could be classified according to ICF. In a reliability test 123/131 (94%) items of randomly chosen free text information were identically classified by two of the authors. On average 2.4 disability categories (range 0-9) were found per patient; the most frequent were 'Sensation of pain' (35.1% of the patients), 'Emotional functions' (34.1%), 'Energy and drive functions' (22.4%), and 'Sleep functions' (16.9%). The dominating ICD-10 diagnostic groups were 'Mental and behavioural disorders' (34.4%) and 'Diseases of the musculoskeletal system and connective tissue' (32.8%). 'Reaction to severe stress and adjustment disorders' (14.7%), and 'Depressive episode' (11.5%) were the most frequent diagnostic codes. Disabilities in mental functions and activity/participation were more commonly described among women, while disabilities related to the musculoskeletal system were more frequent among men. Both ICD-10 diagnoses and ICF categories were dominated by mental and musculoskeletal health problems, but there seems to be gender differences, and ICF classification as a complement to ICD-10 could provide a better understanding of the consequences of diseases and how individual patients can cope with their health problems. ICF is feasible for secondary classifying of free text descriptions of disabilities stated in sick-leave certificates and seems to be useful as a complement to ICD-10 for sick-listing management and research.

To explore how general practitioners view and handle new standards for functional assessments in sickness certification practice. Qualitative study using focus group interviews. Data were analysed according to Giorgi's phenomenological approach and supported by theories on knowledge. General practitioners from three neighbouring counties in Norway. Four focus groups with a total of 23 participants were recruited through the Norwegian Medical Association and its Continuous Medical Education system. The participants reported difficulties and reluctance to act in accordance with new functional assessment demands on both a practical and a conceptual level. In established sickness certification practice functional assessment was described as an unspoken part of the medical examination. After the introduction of formal, written functional assessments they identified problems of terminology, communication, and trust. Strategies were developed to circumvent these problems. A gap was noticeable between the participants' established practice and the new standards' demand for a more theoretical and communicative functional assessment. The general lack of training, being confronted with new terminology, and increasingly high pressure to reduce sickness absences create an atmosphere of insecurity when assessing function.

Diagnosis and duration of sickness absence as predictors for disability pension: results from a three-year, multi-register based* and prospective study.

PubMed

Gjesdal, Sturla; Bratberg, Espen

2003-01-01

A study was undertaken to identify predictors for the transition from long-term sickness absence into disability pension with special emphasis on routinely collected medical information (e.g. diagnoses on sickness certificates) and the duration of sickness-absence spells. The study used a 10% random sample of the Norwegian population of working age (the KIRUT database). Individuals below 60 years of age, with spells of long-term sickness absence starting in 1990-91, where the medical diagnoses on the sickness certificates were known, were identified. This group (4,432 men and 5,645 women) was followed up for three years after the end of sickness absence with regard to disability pension and working status. In logistic regression the following predictors significantly increased the risk of obtaining disability pension during the first three years after the long-term sickness spell: age, part-time employment, and duration of absence > 197 days. Higher education and having children < 11 years significantly decreased the risk. Having the medical diagnoses "mental problems" and diseases in the nervous system, respiratory system, and circulatory systems indicated high risk (compared with musculoskeletal disease). The diagnostic groups "pregnancy-related disease" and "injuries" implied low risk for disability pension. In separate regressions for both genders the "protective effect" of having small children remained only for women. High risk for sickness absence caused by "mental problems" reached significance only for men. Several risk factors for transition from long-term sickness absence into disability pension were identified. The finding that spells of sickness absence with duration up to seven months did not imply increased risk of disability during the first three years may have implications for interventions aimed at long-term sickness absentees.

GPs' negotiation strategies regarding sick leave for subjective health complaints.

2015-03-01

To explore general practitioners' (GPs') specific negotiation strategies regarding sick-leave issues with patients suffering from subjective health complaints. Focus-group study. Nine focus-group interviews in three cities in different regions of Norway. 48 GPs (31 men, 17 women; age 32-65), participating in a course dealing with diagnostic practice and assessment of sickness certificates related to patients with subjective health complaints. The GPs identified some specific strategies that they claimed to apply when dealing with the question of sick leave for patients with subjective health complaints. The first step would be to build an alliance with the patient by complying with the wish for sick leave, and at the same time searching for information to acquire the patient's perspective. This position would become the basis for the main goal: motivating the patient for a rapid return to work by pointing out the positive effects of staying at work, making legal and moral arguments, and warning against long-term sick leave. Additional solutions might also be applied, such as involving other stakeholders in this process to provide alternatives to sick leave. GPs seem to have a conscious approach to negotiations of sickness certification, as they report applying specific strategies to limit the duration of sick leave due to subjective health complaints. This give-and-take way of handling sick-leave negotiations has been suggested by others to enhance return to work, and should be further encouraged. However, specific effectiveness of this strategy is yet to be proven, and further investigation into the actual dealings between doctor and patients in these complex encounters is needed.

The social negotiation of fitness for work: tensions in doctor-patient relationships over medical certification of chronic pain.

PubMed

Wainwright, Elaine; Wainwright, David; Keogh, Edmund; Eccleston, Christopher

2015-01-01

The UK government is promoting the health benefits of work, in order to change doctors' and patients' behaviour and reduce sickness absence. The rationale is that many people 'off sick' would have better outcomes by staying at work; but reducing the costs of health care and benefits is also an imperative. Replacement of the 'sick note' with the 'fit note' and a national educational programme are intended to reduce sickness-certification rates, but how will these initiatives impact on doctor-patient relationships and the existing tension between the doctor as patient advocate and gate-keeper to services and benefits? This tension is particularly acute for problems like chronic pain where diagnosis, prognosis and work capacity can be unclear. We interviewed 13 doctors and 30 chronic pain patients about their experiences of negotiating medical certification for work absence and their views of the new policies. Our findings highlight the limitations of naïve rationalist approaches to judgements of work absence and fitness for work for people with chronic pain. Moral, socio-cultural and practical factors are invoked by doctors and patients to contest decisions, and although both groups support the fit note's focus on capacity, they doubt it will overcome tensions in the consultation. Doctors value tacit skills of persuasion and negotiation that can change how patients conceptualise their illness and respond to it. Policy-makers increasingly recognise the role of this tacit knowledge and we conclude that sick-listing can be improved by further developing these skills and acknowledging the structural context within which protagonists negotiate sick-listing. © The Author(s) 2014.

Abstract Objectives. To explore general practitioners’ (GPs’) specific negotiation strategies regarding sick-leave issues with patients suffering from subjective health complaints. Design. Focus-group study. Setting. Nine focus-group interviews in three cities in different regions of Norway. Participants. 48 GPs (31 men, 17 women; age 32–65), participating in a course dealing with diagnostic practice and assessment of sickness certificates related to patients with subjective health complaints. Results. The GPs identified some specific strategies that they claimed to apply when dealing with the question of sick leave for patients with subjective health complaints. The first step would be to build an alliance with the patient by complying with the wish for sick leave, and at the same time searching for information to acquire the patient's perspective. This position would become the basis for the main goal: motivating the patient for a rapid return to work by pointing out the positive effects of staying at work, making legal and moral arguments, and warning against long-term sick leave. Additional solutions might also be applied, such as involving other stakeholders in this process to provide alternatives to sick leave. Conclusions and implications. GPs seem to have a conscious approach to negotiations of sickness certification, as they report applying specific strategies to limit the duration of sick leave due to subjective health complaints. This give-and-take way of handling sick-leave negotiations has been suggested by others to enhance return to work, and should be further encouraged. However, specific effectiveness of this strategy is yet to be proven, and further investigation into the actual dealings between doctor and patients in these complex encounters is needed.

Sickness absence leads to understaffing and interferes with nursing efficiency and quality. It has been reported in literature that managerial leadership is associated with self-reported sickness absence in the working population. This study investigated the relationship between managerial leadership and sickness absence in health care by associating nurse managers' leadership styles with registered sickness absence among their nursing staff. The cross-sectional study included 699 nurses working in six wards (staff range = 91-140 employees) of a Dutch somatic hospital employing a total of 1,153 persons. The nurse managers heading the wards were asked to complete the Leadership Effectiveness and Adaptability Description questionnaire for situational leadership. The Leadership Effectiveness and Adaptability Description scores were linked to employer-registered nursing staff sickness absence. High relationship-high task behavior (odds ratio [OR] = 0.76, 95% confidence interval [CI] = 0.65-0.85) and high relationship-low task behavior (OR = 0.37, 95% CI = 0.14 -0.98) were inversely related to the number of short (one to seven consecutive days) episodes of sickness absence among the staff. Low relationship-high task styles (OR = 2.44, 95% CI = 1.14-5.22) as well as low relationship-low task styles (OR = 2.44, 95% CI = 1.26-4.71) were positively associated with the number of short episodes of sickness absence. However, the leadership styles only explained 10% of the variance in short episodes of sickness absence. Leadership styles are associated with registered sickness absence. The nursing staff of relationship-oriented nurse managers has fewer short episodes of sickness absence than the staff of task-oriented managers. Training nurse managers in relational leadership styles may reduce understaffing and improve nursing efficiency and quality.

Profound changes are taking place in the Swedish welfare state. The general population's attitudes are important insofar changes will be perceived as fair and effective to become implemented. The aim was to study attitudes to the strictness of the sick-leave rules, relocation to other work tasks after 3 months of sick leave and applications for new jobs after 6 months of sick leave. Eligible for this questionnaire study were 1,140 individuals aged 19 to 64 years. Their attitudes were analyzed in relation to age, gender, political ideology and health status. Health status was measured as sick-leave experiences, self-reported health and level of symptoms. Showed that 42% considered the sick-leave rules to be too strict, 60% found relocation to other work tasks to be good while 35% found that applications for new work were good. In logistic regression analyses, high sick-leave experience was associated with increased odds of finding the sick-leave rules too strict and disagreement with relocation to other work tasks or application for new jobs. In conclusion, strong support was found for relocation to other work tasks with the present employer. Earlier research on returning to work has found workplace interventions to be efficient. From a policy perspective it seems relevant to promote such interventions given the strong public opinion in their favor.

In the study, we checked: 1) how the simulator test conditions affect the severity of simulator sickness symptoms; 2) how the severity of simulator sickness symptoms changes over time; and 3) whether the conditions of the simulator test affect the severity of these symptoms in different ways, depending on the time that has elapsed since the performance of the task in the simulator. We studied 12 men aged 24-33 years (M = 28.8, SD = 3.26) using a truck simulator. The SSQ questionnaire was used to assess the severity of the symptoms of simulator sickness. Each of the subjects performed three 30-minute tasks running along the same route in a driving simulator. Each of these tasks was carried out in a different simulator configuration: A) fixed base platform with poor visibility; B) fixed base platform with good visibility; and C) motion base platform with good visibility. The measurement of the severity of the simulator sickness symptoms took place in five consecutive intervals. The results of the analysis showed that the simulator test conditions affect in different ways the severity of the simulator sickness symptoms, depending on the time which has elapsed since performing the task on the simulator. The simulator sickness symptoms persisted at the highest level for the test conditions involving the motion base platform. Also, when performing the tasks on the motion base platform, the severity of the simulator sickness symptoms varied depending on the time that had elapsed since performing the task. Specifically, the addition of motion to the simulation increased the oculomotor and disorientation symptoms reported as well as the duration of the after-effects.

To identify predictive factors for work capacity in patients with musculoskeletal disorders. A descriptive, evaluative, quantitative study. The study was based on 385 patients who participated in a rehabilitation programme. Patients were divided into 2 groups depending on their ability to work. The groups were compared with each other with regard to sociodemographic factors, diagnoses, disability pension and number of sick days. The patient's level of exercise habits, ability to undertake activities, physical capacity, pain and quality of life were compared further using logistic regression analysis. Predictive factors for work capacity, such as ability to undertake activities, quality of life and fitness on exercise, were identified as important independent factors. Other well-known factors, i.e. gender, age, education, pain and earlier sickness certification periods, were also identified. Factors that were not significantly different between the groups were employment status, profession, diagnosis and levels of exercise habits. Identifying predictors for ability to return to work is an essential task for deciding on suitable individual rehabilitation. This study identified new predictive factors, such as ability to undertake activities, quality of life and fitness on exercise.

Unemployment, labor force composition and sickness absence: a panel data study.

PubMed

Askildsen, Jan Erik; Bratberg, Espen; Nilsen, Oivind Anti

2005-11-01

Sickness absence tends to be negatively correlated with unemployment rates. In addition to pure health effects, this may be due to moral hazard behavior by workers who are fully insured against income loss during sickness and to physicians who meet demand for medical certificates. Alternatively, it may reflect changes in the composition of the labor force, with more sickness-prone workers entering the labor force in upturns. A panel of Norwegian register data is used to analyze long-term sickness absences. The unemployment rate is shown to be negatively associated with the probability of absence, and with the number of days of sick leave. Restricting the sample to workers who are present in the whole sample period, the negative relationship between absence and unemployment becomes clearer. This indicates that procyclical variations in sickness absence are caused by established workers and not by the composition of the labor force.

In this study, we investigated the effects of mild motion sickness and sopite syndrome on multitasking cognitive performance. Despite knowledge on general motion sickness, little is known about the effect of motion sickness and sopite syndrome on multitasking cognitive performance. Specifically, there is a gap in existing knowledge in the gray area of mild motion sickness. Fifty-one healthy individuals performed a multitasking battery. Three independent groups of participants were exposed to two experimental sessions. Two groups received motion only in the first or the second session, whereas the control group did not receive motion. Measurements of motion sickness, sopite syndrome, alertness, and performance were collected during the experiment Only during the second session, motion sickness and sopite syndrome had a significant negative association with cognitive performance. Significant performance differences between symptomatic and asymptomatic participants in the second session were identified in composite (9.43%), memory (31.7%), and arithmetic (14.7%) task scores. The results suggest that performance retention between sessions was not affected by mild motion sickness. Multitasking cognitive performance declined even when motion sickness and soporific symptoms were mild. The results also show an order effect. We postulate that the differential effect of session on the association between symptomatology and multitasking performance may be related to the attentional resources allocated to performing the multiple tasks. Results suggest an inverse relationship between motion sickness effects on performance and the cognitive effort focused on performing a task. Even mild motion sickness has potential implications for multitasking operational performance.

This study aims to develop a motion sickness measurement index in a virtual reality (VR) environment. The VR market is in an early stage of market formation and technological development, and thus, research on the side effects of VR devices such as simulator motion sickness is lacking. In this study, we used the simulator sickness questionnaire (SSQ), which has been traditionally used for simulator motion sickness measurement. To measure the motion sickness in a VR environment, 24 users performed target selection tasks using a VR device. The SSQ was administered immediately after each task, and the order of work was determined using the Latin square design. The existing SSQ was revised to develop a VR sickness questionnaire, which is used as the measurement index in a VR environment. In addition, the target selection method and button size were found to be significant factors that affect motion sickness in a VR environment. The results of this study are expected to be used for measuring and designing simulator sickness using VR devices in future studies. Copyright © 2018 Elsevier Ltd. All rights reserved.

Unemployment has increased in Norway during the last years. In order to study the impact of unemployment on primary health care in Hedmark county, a questionnaire was sent to 132 general practitioners. 70% replied. Some of the questions dealt with the doctors' requests for social security benefits for patients whose problems were related to loss of job. During one week 30% of the doctors had written this kind of sickness certificate. Further, during one month, 35% had recommended rehabilitation or disability pension. During the last year, 26% of the doctors had received requests activity proposing sickness certification for some of their employees from companies that were forced to reduce activity. The author discusses these results, and outlines the possible consequences for patient, doctor and the social security system.

Objective To explore the underlying mechanisms between organisational downsizing and deterioration of health of employees. Design Longitudinal cohort study. Data were assembled from before downsizing (time 1); during major downsizing affecting some job categories (time 2); and after downsizing (time 3). Contributions of changes in work, support, and health related behaviours between time 1 and time 2 to the relation between downsizing and sickness absence at time 3 were assessed by multilevel modelling. Mean length of follow up was 4.9 years. Setting Raisio, a town in Finland. Subjects 764 municipal employees who remained in employment after downsizing. Main outcome measures Records of absences from work from all causes with medical certificate. Results Downsizing was associated with negative changes in work, impaired support from spouse, and increased prevalence of smoking. Sickness absence rate from all causes was 2.17 (95% confidence interval 1.54 to 3.07) times higher after major downsizing than after minor downsizing. Adjustment for changes in work (for instance, physical demands, job control, and job insecurity) diminished the relation between downsizing and sickness absence by 49%. Adjustments for impaired social support or increased smoking did not alter the relation between downsizing and sickness absence. The findings were unaffected by sex and income. Conclusions The exploration of potential mediating factors provides new information about the possible causal pathways linking organisational downsizing and health. Downsizing results in changes in work, social relationships, and health related behaviours. The observed increase in certificated sickness absence was partially explained by concomitant increases in physical demands and job insecurity and a reduction in job control. A considerable proportion of the increase, however, remained unexplained by the factors measured. PMID:10753148

Factors influencing return to work after illness in France.

Few studies have been published about the factors influencing return to work after sickness absence. To identify medical and occupational factors influencing the type of fitness certificate given by occupational physicians before employees return to work after sickness absence. A cross-sectional study was undertaken over 3 months in several health services in France. Workers undergoing a medical examination before returning to work after a period of sickness absence of at least 3 weeks were included. Medical and occupational factors were collected using a questionnaire. The relationship between different factors and certification of fitness was assessed by univariate and multivariate analyses. Among the 402 workers included, 64% were considered fit to return to work. Being older, strenuous work, prolonged sick leave and fear of returning to work appeared to be negative factors influencing the return to a previous job. In contrast, having an education level higher than secondary school, being satisfied at work, perception of very good health and benefitting from satisfactory professional relationships appeared to favour return to work. We developed a predictive score of not being fit to return to work after illness. Our study highlighted the relationship between medical and occupational factors with problems returning to work. The predictive score may be used by occupational physicians as a screening tool to identify those who are likely to have difficulties returning to work after illness, so that their working conditions can be modified to take this into consideration.

Intramuscular (IM) injections of promethazine in 25 mg or 50 mg dosages are commonly used to treat space motion sickness in astronauts. The present study examined the effects of IM injections of promethazine on neuropsy-chological performance, mood states, and motion sickness tolerance in humans. Twelve men, mean age 36 plus or minus 3.1 participated in one training (no injections) and three treatment conditions: a 25 mg injection of promethazine, a 50 mg injection of promethazine, and a placebo injection of sterile saline. Each condition, spaced at 7 day intervals, required an 8-10 hr session in which subjects were given four repetitions of 12 performance tasks, and one rotating chair motion sickness test. On the training day subjects were trained on each task to establish stability and proficiency. On treatment days, the order in which the drug or placebo was assigned to subjects was counter-balanced and a double-blind technique was used. Statistically significant decrements in performance were observed on 10 of 12 tasks when subjects were given 25 mg or 50 mg of promethazine as compared to the placebo. Performance decrements were associated with mean blood alcohol dose equivalency levels of 0.085% for 25 mg and 0. 1 37% for 50 mg dosages. The mood scale results showed significant changes in individual subjective experiences with maximum deterioration in the arousal state and fatigue level. When compared to placebo significant increases in motion sickness tolerance were found for both dosages of promethazine. These data suggest that effective dosages of promethazine currently used to counteract motion sickness in astronauts may significantly impair task components of their operational performance.

Mental disorders strongly influence work capability in young adults, but it is not clear which disorders that are most strongly associated with sick leave, and which diagnoses that are stated on the sick leave certificates. Better knowledge of the impairments associated with different mental disorders is needed for optimal planning of interventions and prioritization of health services. In the current study, we investigate the prospective associations between eight mood, anxiety, and alcohol use disorders, and later sick leave granted for mental, somatic, or any disorder. Lifetime mental disorders were assessed by structured diagnostic interviews in 2,178 young adults followed for eight years with registry data on sick leave. Relative risk ratios were estimated for the associations between each mental disorder and the different forms of sick leave. All included diagnoses were associated with later sick leave. In adjusted analyses, major depressive disorder and generalized anxiety disorder were the strongest predictors of sick leave granted for mental disorders, whereas social anxiety disorder and specific phobia were the strongest predictors of sick leave granted for somatic disorders. Specific phobia and major depressive disorder had the highest attributable fractions for all-cause sick leave. Mood and anxiety disorders constituted independent risk factors for all cause sick leave, whereas alcohol use disorders seemed to be of less importance in young adulthood. Disorders characterised by distress were most strongly associated with sick leave granted for mental disorders, whereas disorders characterised by fear primarily predicted sick leave granted for somatic conditions. A large part of all sick leave is related to specific phobia, due to the high prevalence of this disorder. The impairment associated with this common disorder may be under-acknowledged, and it could decrease work capacity among individuals with somatic disorders. This disorder has good treatment response and may be overlooked as a target for interventions aimed at prevention of sick leave.

The aim of this study was to examine whether employees in pre-schools that implemented a participatory organizational-level intervention focusing on the core task at work had a lower incidence of short-term sickness absence compared to employees in the control group. The cluster randomized controlled trial (RCT) comprised 78 pre-schools that were allocated to the intervention (44 pre-schools with 1760 employees) or control (34 pre-schools with 1279 employees) group. The intervention lasted 25 months and followed a stepwise and structured approach, consisting of seminars, workshops, and workplace-directed intervention activities focusing on the core task at work. Using Poisson regression, we tested differences in incidence rates in short-term sickness absence between the intervention and control groups during a 29-months follow-up. Estimated short-term sickness absence days per person-year during follow-up were 8.68 and 9.17 in the intervention and control groups, respectively. The rate ratio (RR) for comparing incident sickness absence in the intervention to control groups during follow-up was 0.93 [95% confidence interval (95% CI) 0.86-1.00] in the crude analysis and 0.89 (95% CI 0.83-0.96) when adjusting for age, sex, job group, type and size of workplace, and workplace average level of previous short-term sickness absence. A supplementary analysis showed that the intervention also was associated with a reduced risk of long-term sickness absence with a crude RR of 0.83 (95% CI 0.69-0.99) and an adjusted RR of 0.84 (95% CI 0.69-1.01). Pre-school employees participating in an organizational-level occupational health intervention focusing on the core task at work had a lower incidence of short-term sickness absence during a 29-month follow-up compared with control group employees.

Eighteen men were randomly assigned to three groups matched for susceptibility to Coriolis motion sickness. All subjects were given six Coriolis Sickness Susceptibility Index (CSSI) tests separated by 5-d intervals. Treatment Group I subjects were taught to control their own autonomic responses before the third, fourth, and fifth CSSI tests (6 h total training). Group II subjects were given 'sham' training in an alternative cognitive task under conditions otherwise identical to those of Group I. Group III subjects received no treatment. Results showed that Group I subjects could withstand the stress of Coriolis acceleration significantly longer after training. Neither of the other two groups changed significantly.

Working ability is known to be related to good physical condition, clear work tasks, positive feedback and other occupational, organizational and psychosocial factors. In Sweden, high levels of sickness absence are due to stress-related disorders and musculoskeletal pain. To identify work health characteristics in a working population with a large variety of professional skills and occupational tasks. Employers' data on occupation, sickness absence, age and gender in a working population of 11 occupational groups and questionnaire responses regarding work-organization, environment, work stress, pain, health, and socio-demographic factors were collected. Employees with no history of sick-leave were compared with those with a history of sick-leave (1-182 days, mean 25 days). Of 2641 employees, 1961 participated. Those with no history of sick-leave reported less work-related pain, work-related stress, sleep disturbances, worry about their health, 'sick-presenteeism', monotonous work, bent and twisted working positions and exposure to disturbing noise than those with a history of sick-leave (P < 0.001). They also reported better health, support from superiors, having influence on their working hours and evening and week-end working, longer working hours per week (P < 0.001) and more regular physical training (P < 0.01). Socio-demographic factors were less important than gender, and differences in responses between occupational groups were also found. Workers without a history of sick-leave experienced less stress, sleep disturbances, worry about their own health and less neck, shoulder and back pain and more support from their superiors and influence on their working hours.

Chikungunya fever (CHIK) generally causes temporary sick leave, affecting groups of productive age, which represents a significant economic impact from the labor point of view. The objective was to estimate costs of disability due to chikungunya in the Instituto Mexicano del Seguro Social (IMSS) in Guerrero, Mexico. Cost assessment of working population from IMSS in Guerrero who met the definition of case for CHIK and took sick leave, which was registered in the Original Disability Certificates (OCI, according to its initials in Spanish) processed from January to April, 2015. Paid sick days were multiplied by the current minimum wage of the municipality of Acapulco (geographical area A, general = $ 70.10: seventy pesos with 10 cents per day]). Of all the OCIs, 31.5% (38 271/12 062) met the criteria for CHIK with a total of 41 197 prescribed days and 14 941 paid sick days with an estimated cost of 2 397 393.40 pesos (two million, three hundred and ninety seven thousand, three hundred and ninety three dollars and forty cents). Sick leaves increase the costs in health systems. These costs increase as increases the number of days granted. The average number of days granted is consistent with the information published in different articles.

Workplace phobia is defined as a phobic anxiety reaction with symptoms of panic occurring when thinking of or approaching the workplace. People suffering from workplace phobia regularly avoid confrontation with the workplace and are often on sick leave. The specific characteristics of workplace phobia are investigated empirically in comparison to established anxiety disorders. Two hundred thirty patients from an inpatient psychosomatic rehabilitation hospital were interviewed concerning workplace phobia and established anxiety disorders. Additionally, the patients filled in self-rating questionnaires on general and workplace phobic symptom load. Subjectively perceived degree of work load, sick leave, and therapy participation were assessed. Participants with workplace phobia reached significantly higher scores in workplace phobia self-rating than did participants with established anxiety disorders. A similar significant difference was not found concerning the general psychosomatic symptom load. Workplace phobics were more often on sick leave than patients with established anxiety disorders. Workplace phobia can occur as an alonestanding anxiety disorder. It has an own clinical value due to its specific consequences for work participation. Workplace phobia requires special therapeutic attention and treatment instead of purely 'sick leave' certification.

Aim To investigate the attitudes to health and work of general practitioners (GPs) with training in occupational medicine (OM) compared with non-OM trained GPs, since the introduction of the fit note. Changes to the UK sickness certification system since 2010 and the introduction of the fit note required GPs to change their focus to what patients can do, rather than what they cannot do in relation to work. In an effort to reduce the UK sickness absence burden, GPs completion of the fit note should help to keep people in work, or assist patients to return to work as quickly as possible after a period of absence. Questionnaire data were collected via the 7th National General Practitioner Worklife Survey. Findings Results indicate that responses from GPs who had undertaken training in OM, and GPs having received some form of work and health training in the 12-month period before the study were associated with significantly more positive attitudes to patients' returning to work and to the fit note. This study reveals evidence of a difference between trained and non-trained GPs in their attitude to the fit note, and to work and health generally. Further work investigating the effect of specific training in OM on the management and recognition of ill-health by GPs is recommended.

Our goal was to determine how sleep deprivation, nauseogenic motion, and a combination of motion and sleep deprivation affect cognitive vigilance, visual-spatial perception, motor learning and retention, and balance. We exposed four groups of subjects to different combinations of normal 8h sleep or 4h sleep for two nights combined with testing under stationary conditions or during 0.28Hz horizontal linear oscillation. On the two days following controlled sleep, all subjects underwent four test sessions per day that included evaluations of fatigue, motion sickness, vigilance, perceptual discrimination, perceptual learning, motor performance and learning, and balance. Sleep loss and exposure to linear oscillation had additive or multiplicative relationships to sleepiness, motion sickness severity, decreases in vigilance and in perceptual discrimination and learning. Sleep loss also decelerated the rate of adaptation to motion sickness over repeated sessions. Sleep loss degraded the capacity to compensate for novel robotically induced perturbations of reaching movements but did not adversely affect adaptive recovery of accurate reaching. Overall, tasks requiring substantial attention to cognitive and motor demands were degraded more than tasks that were more automatic. Our findings indicate that predicting performance needs to take into account in addition to sleep loss, the attentional demands and novelty of tasks, the motion environment in which individuals will be performing and their prior susceptibility to motion sickness during exposure to provocative motion stimulation.

Motion sickness (MS) is a stressor commonly attributed with causing serious navigational and performance errors. The distinct nature of MS suggests this state may have distinct neural markers distinguishable from other states known to affect performance (e.g., stress, fatigue, sleep deprivation, high workload). This pilot study used new high-resolution electro-encephalograph (EEG) technologies to identify distinct neuronal activation changes that occur during MS. Brain EEG activity was monitored while subjects performed a ball-tracking task and viewed stimuli on a projection screen intended to induce motion sickness/spatial disorientation. Results show the presence of EEG spectral changes in all subjects who developed motion sickness when compared to baseline levels. These changes included: 1) low frequency (1 to 10 Hz) changes that may reflect oculomotor movements rather than intra-cerebral sources; 2) increased spectral power across all frequencies (attributable to increased scalp conductivity related to sweating), 3) local increases of power spectra in the 20-50 Hz range (likely attributable to external muscles on the skull) and; 4) a central posterior (occipital) independent component that shows suppression of a 20 Hz peak in the MS condition when compared to baseline. Further research is necessary to refine neural markers, characterize their origin and physiology, to distinguish between motion sickness and other states and to enable markers to be used for operator state monitoring and the designing of interventions for motion sickness.

[Pregnancy-related and work-related sick leave of pregnant women].

PubMed

Tophøj, A; Mortensen, J T

1999-09-06

Pregnant women are allowed sick leave (SL) due to obstetrical or occupational risk factors. The aim was to describe reasons for SL during pregnancy. Pregnant women in a Danish county applying for SL were consecutively included in the study during 12 months in 1991-92. Data were obtained by questionnaires mailed to the women and their medical doctors. Of 1483 pregnant women on SL, 994 participated. Approximately 96% were on SL due to obstetrical risk factors. Occupational factors contributed to SL in at least 50% of the cases, mainly when working in a standing or walking position or when lifting. The women were rarely replaced in other jobs before leaving work. On average the women were absent for 83 days before official pregnancy leave started. Although SL during pregnancy is overwhelmingly due to obstetrical risk factors, occupational factors often contribute. Occupational Health and Safety Organizations are rarely involved at the workplace before issuing a sick leave certificate.

Phenytoin as a countermeasure for motion sickness in NASA maritime operations

NASA Technical Reports Server (NTRS)

Woodard, Daniel; Knox, Glenn; Myers, K. J.; Chelen, William; Ferguson, Becki

1993-01-01

Seasickness is the most prevalent form of motion sickness and is an operational problem during Space Shuttle Solid-fueled Rocket Booster (SRB) retrieval. Phenytoin has been shown to protect against motion sickness induced by Coriolis stress. We exposed SRB recovery personnel to off-vertical rotation and sea motion after phenytoin or placebo. Phenytoin blood levels of at least 9 micrograms/ml were protective against motion sickness at sea. No change in susceptibility to nitrogen narcosis was seen in divers in chamber tests at 460 KPa. Phenytoin was used during the performance of critical and hazardous tasks during training and actual SRB recovery operations. Phenytoin is an effective operational countermeasure for motion sickness for selected SRB crew members.

The National Aeronautics and Space Administration (NASA) has identified a potential risk of spatial disorientation, motion sickness, and degraded performance to astronauts during re-entry and landing of the proposed Orion crew vehicle. The purpose of this study was to determine if a physiological training procedure, Autogenic-Feedback Training Exercise (AFTE), can mitigate these adverse effects. Fourteen men and six women were assigned to two groups (AFTE, no-treatment Control) matched for motion sickness susceptibility and gender. All subjects received a standard rotating chair test to determine motion sickness susceptibility; three training sessions on a manual performance task; and four exposures in the rotating chair (Orion tests) simulating angular accelerations of the crew vehicle during re-entry. AFTE subjects received 2 h of training before Orion tests 2, 3, and 4. Motion sickness symptoms, task performance, and physiological measures were recorded on all subjects. Results showed that the AFTE group had significantly lower symptom scores when compared to Controls on test 2 (p = .05), test 3 (p = .03), and test 4 (p = .02). Although there were no significant group differences on task performance, trends showed that AFTE subjects were less impaired than Controls. Heart rate change scores (20 rpm minus baseline) of AFTE subjects indicated significantly less reactivity on Test 4 compared to Test 1 (10.09 versus 16.59, p = .02), while Controls did not change significantly across tests. Results of this study indicate that AFTE may be an effective countermeasure for mitigating spatial disorientation and motion sickness in astronauts. Copyright © 2018. Published by Elsevier B.V.

Nationwide representative survey of the use of psychiatric outpatient services in Germany. Every fifth patient of several psychiatric outpatient services was surveyed on one index day (27 (th) of May 2008) with respect to sociodemographic characteristics, ICD-10 diagnoses, difficulties in communication, treatment duration, and number of sickness certificates. Patients with immigrant background comprised 32.5 % of all patients. Compared to German patients, patients with immigrant background received significantly more neurotic, stress-related and somatoform disorders (F4). Turkish patients received significantly more mood (affective) disorders diagnoses (F3), compared to German and Eastern Europe patients. Immigrants had shorter treatment duration and a higher number of sickness certificates. Eastern European patients had a significantly higher education, compared to patients with Turkish background. Patients with immigrant background were younger compared to German patients and had significantly more children. The utilization of outpatient psychiatric services by patients with a migratory background is high. This suggests that immigrants benefit from the multiprofessional team and the low-treshold service offered by outpatient units. © Georg Thieme Verlag KG Stuttgart · New York.

The repercussion of health-disease state on social life or individual includes his/her work performance. In many countries, social security is one of the options for diffusing and buffering the impact of the disease. This paper is focused on the analysis of the unjustified prescription of temporary sick leave certificates (CITT), which combines the social security medical components and economic benefits (subsidies). The objective is to analyze the mechanism of prescription of CITT from the perspective of health economics and health care services. The detailed flow of CITT at the Mexican Institute of Social Security is described, as are some concepts of the health economics perspective that contribute to explain the prescription of CITT. Statistical data of sick leaves due to work-related and non-work-related diseases are presented from the institutional perspective. Finally, it is emphasized that although CITT are a medical prescription, it is advisable to take into account the economic perspective and its concepts in order to achieve an efficient use of resources.

Work problems due to low back pain: what do GPs do? A questionnaire survey.

PubMed

Coole, Carol; Watson, Paul J; Drummond, Avril

2010-02-01

Low back pain can affect work ability and remains a main cause of sickness absence. In the UK the GP is usually the first contact for patients seeking health care. The UK government intends that the GP will continue to be responsible for sickness certification and work advice. This role requires a considerable level of understanding of work rehabilitation, and effective communication between GPs, patients, employers and therapists. The aim of this study was to identify GPs' current practice in managing patients whose ability to work is affected by low back pain, and their perception of the support services required. A postal questionnaire of 441 GPs in the South Nottinghamshire area of the UK was carried out. Areas covered included referral patterns, sickness certification, and communication with therapists and employers. There was a 54.6% response rate. The majority of GPs (76.8%) reported that they did not take overall responsibility for managing the work problems of patients arising from low back pain. Few 'mainly agreed' that they initiated communication with employers (2.5%) and/or therapists (10.4%) regarding their patients' work. The results of this study demonstrate that most GPs do not readily engage in vocational rehabilitation and do not initiate contact with employers or other health care practitioners regarding patients' work problems. Thus the current government expectation that GPs are able to successfully manage this role may be unrealistic; considerable training and a change in the GPs' perception of their role will be required.

Human heart rate variability relation is unchanged during motion sickness

Mullen, T. J.; Berger, R. D.; Oman, C. M.; Cohen, R. J.

1998-01-01

In a study of 18 human subjects, we applied a new technique, estimation of the transfer function between instantaneous lung volume (ILV) and instantaneous heart rate (HR), to assess autonomic activity during motion sickness. Two control recordings of ILV and electrocardiogram (ECG) were made prior to the development of motion sickness. During the first, subjects were seated motionless, and during the second they were seated rotating sinusoidally about an earth vertical axis. Subjects then wore prism goggles that reverse the left-right visual field and performed manual tasks until they developed moderate motion sickness. Finally, ILV and ECG were recorded while subjects maintained a relatively constant level of sickness by intermittent eye closure during rotation with the goggles. Based on analyses of ILV to HR transfer functions from the three conditions, we were unable to demonstrate a change in autonomic control of heart rate due to rotation alone or due to motion sickness. These findings do not support the notion that moderate motion sickness is manifested as a generalized autonomic response.

Observed behaviours of pre-term children in a social play situation with classroom peers.

A number of studies have reported social adjustment problems in pre-term children. To observe the pre-term's behaviour in an experimental situation and correlate these observed behaviours with the children's peer-rated social behaviours (withdrawal, aggression and sociability/leadership). Of 56 pre-term children, 24 were classified as the sick pre-term (SPT) group and 32 children as the healthy pre-term (HPT) group. The comparison group comprised 56 healthy full-terms. The experimental situation used a game called Rush Hour, a labyrinth-type board game. The play situation was videotaped and behaviours (number of consecutive moves) were coded in real time. At 12 years of age, the sick pre-term (SPT) group exhibited fewer consecutive moves during the game than the other two groups, especially when the task became more complex (involving four consecutives moves). Moreover, the Complex Task Index was correlated with the social withdrawal score rated by peers. The at-birth sick pre-term gradually became less involved in a complex decision-making task and this was understood as a lesser ability to make a decision in a complex setting.

Work and family: associations with long-term sick-listing in Swedish women - a case-control study.

PubMed

Sandmark, Hélène

2007-10-11

The number of Swedish women who are long-term sick-listed is high, and twice as high as for men. Also the periods of sickness absence have on average been longer for women than for men. The objective of this study was to investigate the associations between factors in work- and family life and long-term sick-listing in Swedish women. This case-control study included 283 women on long-term sick-listing > or =90 days, and 250 female referents, randomly chosen, living in five counties in Sweden. Bivariate and multivariate logistic regression analyses with odds ratios were calculated to estimate the associations between long-term sick-listing and factors related to occupational work and family life. Long-term sick-listing in women is associated with self-reported lack of competence for work tasks (OR 2.42 1.23-11.21 log reg), workplace dissatisfaction (OR 1.89 1.14-6.62 log reg), physical workload above capacity (1.78 1.50-5.94), too high mental strain in work tasks (1.61 1.08-5.01 log reg), number of employers during work life (OR 1.39 1.35-4.03 log reg), earlier part-time work (OR 1.39 1.18-4.03 log reg), and lack of influence on working hours (OR 1.35 1.47-3.86 log reg). A younger age at first child, number of children, and main responsibility for own children was also found to be associated with long-term sick-listing. Almost all of the sick-listed women (93%) wanted to return to working life, and 54% reported they could work immediately if adjustments at work or part-time work were possible. Factors in work and in family life could be important to consider to prevent women from being long-term sick-listed and promote their opportunities to remain in working life. Measures ought to be taken to improve their mobility in work life and control over decisions and actions regarding theirs lives.

Stroboscopic Goggles as a Countermeasure for Dynamic Visual Acuity and Landing Sickness After Long-Duration Spaceflight

Gravity transitions cause changes in the vestibulo-occular reflex (VOR), which manifests as poor gaze control, a decrement in dynamic visual acuity (the ability to maintain gaze while in motion), both of which are caused by retinal slip. Retinal slip, the inability to keep an image focused on the retina, can drive or worsen sensory conflict, resulting in motion sickness (MS). Currently 100% of returning crewmembers report MS symptoms, which might affect their ability to perform mission critical tasks immediately after landing. Reschke et al. (2007) demonstrate that stroboscopic vision goggles improve motion sickness onset and symptom severity in motion sickness driven by retinal slip.

Influence of a visual display and frequency of whole-body angular oscillation on incidence of motion sickness.

1982-06-01

Visual search within a head-fixed display consisting of a 12 X 12 digit matrix is degraded by whole-body angular oscillation at 0.02 Hz (+/- 155 degrees/s peak velocity), and signs and symptoms of motion sickness are prominent in a number of individuals within a 5-min exposure. Exposure to 2.5 Hz (+/- 20 degrees/s peak velocity) produces equivalent degradation of the visual search task, but does not produce signs and symptoms of motion sickness within a 5-min exposure.

[Sickness absence associated with major life events].

Markussen, Simen; Røgeberg, Ole

2012-05-29

Sickness absence in the Norwegian workplace doubled in the period 1993-2003. However, the extent to which the driving factors were medical or non-medical remains unclear, as does the extent to which the cause may be found in the composition of the workforce. A differences-in-differences regression model was used to estimate the added sickness absence associated with major life events such as separation, death of spouse and pregnancy in the period 1993-2005. The data were obtained from administrative registers covering the entire Norwegian population, and include all absence periods of 16 days' duration or more reported by a doctor's medical certificate. The primary outcome measures were incidence (the proportion of absentees in a given time window) and absence (the proportion of sick days in a given time window). The level of absence among employees exposed to the specified life events was compared to control groups matched for gender, age, education and income. In 1993, people in each of the three groups exposed to major life events had more frequent and longer periods of absence than people in the control groups. This added sickness absence increased between 1993 and 2005. The changes in added sickness absence were at times significant, particularly for pregnant women. While sickness absence among pregnant women in 1993 was 15.4 percentage points higher than in the control group, the difference had increased to 24.8 percentage points in 2005. We find it improbable for the increase in added sickness absence to be caused by changes in the medical impact of life events or alterations in the workforce composition. We believe the increase is caused by changing attitudes among the working population and in the medical profession towards sickness absence on grounds that are not strictly medical, combined with improved social acceptance and diagnosis of mental health issues, and/or a medicalisation of natural health variations (pregnancy) and emotional distress (grief).

Work load, job control and risk of leaving work by sickness certification before delivery, Norway 1989.

Strand, K; Wergeland, E; Bjerkedal, T

1997-09-01

Sickness absence in pregnancy has been shown to be associated with strenuous working conditions and parity. So far, few studies have made adjustments for possible interaction and confounding. Such adjustments are needed to more precisely identify targets for preventive measures. We have, therefore, in a representative population of pregnant employees in Norway 1989, computed adjusted odds ratios for leaving work by sickness absence more than three (LSC > 3) and eight (LSC > 8) weeks before delivery according to working conditions identified as risk factors in earlier studies; adjusted for job control, domestic conditions and sickness absence the year prior to pregnancy. The cumulative percentage of LSC > 8 and LSC > 3 was 26.4 and 51.1. Ergonomically strenuous postures and heavy lifting increased the risk of both outcomes. In addition, shift work and hectic work pace increased the risk of LSC > 3. Influence on breaks reduced risk. Only para experienced reduced risk of LSC when working part-time. Sicklisting the year prior to pregnancy had no confounding effect, which suggest that pregnancy represents a new incompatibility with work. Preventive measures should address work postures and heavy lifting, as well as conditions influencing the woman's control with her time.

2011-01-01

Background Staying in work may benefit patients with chronic pain, but can be difficult for GPs to negotiate with patients and their employers. The new fit note is designed to help this process, but little is known of how it is operating. Aim To explore GPs' views on the fit note, with particular reference to sickness certification for patients with chronic pain. Design and setting Qualitative study using semi-structured interviews in eight primary care trusts in south-west England. Method In-depth interviews with 13 GPs. Results GPs reported that the rationale behind the fit note is sound and that it may help patients with chronic pain to return to work earlier. However, GPs also reported barriers to successful fit note use, including the need to preserve doctor–patient relationships, inconsistent engagement from employers, GPs' lack of specialist occupational health knowledge, issues with fit note training, and whether a new form can achieve cultural shift. Conclusion While doctors agree that good work improves health outcomes, they do not think that fit notes will greatly alter sickness-certification rates without more concerted initiatives to manage the tripartite negotiation between doctor, patient, and employer.

Modeling the cost of influenza: the impact of missing costs of unreported complications and sick leave

PubMed Central

2010-01-01

Background Estimating the economic impact of influenza is complicated because the disease may have non-specific symptoms, and many patients with influenza are registered with other diagnoses. Furthermore, in some countries like Norway, employees can be on paid sick leave for a specified number of days without a doctor's certificate ("self-reported sick leave") and these sick leaves are not registered. Both problems result in gaps in the existing literature: costs associated with influenza-related illness and self-reported sick leave are rarely included. The aim of this study was to improve estimates of total influenza-related health-care costs and productivity losses by estimating these missing costs. Methods Using Norwegian data, the weekly numbers of influenza-attributable hospital admissions and certified sick leaves registered with other diagnoses were estimated from influenza-like illness surveillance data using quasi-Poisson regression. The number of self-reported sick leaves was estimated using a Monte-Carlo simulation model of illness recovery curves based on the number of certified sick leaves. A probabilistic sensitivity analysis was conducted on the economic outcomes. Results During the 1998/99 through 2005/06 influenza seasons, the models estimated an annual average of 2700 excess influenza-associated hospitalizations in Norway, of which 16% were registered as influenza, 51% as pneumonia and 33% were registered with other diagnoses. The direct cost of seasonal influenza totaled US$22 million annually, including costs of pharmaceuticals and outpatient services. The annual average number of working days lost was predicted at 793 000, resulting in an estimated productivity loss of US$231 million. Self-reported sick leave accounted for approximately one-third of the total indirect cost. During a pandemic, the total cost could rise to over US$800 million. Conclusions Influenza places a considerable burden on patients and society with indirect costs greatly exceeding direct costs. The cost of influenza-attributable complications and the cost of self-reported sick leave represent a considerable part of the economic burden of influenza. PMID:21106057

Adjustment latitude and attendance requirements as determinants of sickness absence or attendance. Empirical tests of the illness flexibility model.

PubMed

Johansson, Gun; Lundberg, Ingvar

2004-05-01

This study investigates whether the two dimensions of illness flexibility at work, adjustment latitude and attendance requirements are associated to sickness absence and sickness attendance. Adjustment latitude describes the opportunities people have to reduce or in other ways change their work-effort when ill. Such opportunities can be to choose among work tasks or work at a slower pace. Attendance requirements describe negative consequences of being away from work that can affect either the subject, work mates or a third party. In a cross-sectional design data based on self-reports from a questionnaire from 4924 inhabitants in the county of Stockholm were analysed. The results showed that low adjustment latitude, as predicted, increased women's sickness absence. However, it did not show any relation to men's sickness absence and men's and women's sickness attendance. Attendance requirements were strongly associated to both men's and women's sickness absence and sickness attendance in the predicted way. Those more often required to attend were less likely to be absent and more likely to attend work at illness. As this is the first study of how illness flexibility at work affects behaviour at illness, it was concluded that more studies are needed.

2015-12-01

Simulator sickness is the occurrence of motion-sickness like symptoms that can occur during use of simulators and virtual reality technologies. This study investigated individual factors that contributed to simulator sickness and dropout while using a desktop driving simulator. Eighty-eight older adult drivers (mean age 72.82±5.42years) attempted a practice drive and two test drives. Participants also completed a battery of cognitive and visual assessments, provided information on their health and driving habits, and reported their experience of simulator sickness symptoms throughout the study. Fifty-two participants dropped out before completing the driving tasks. A time-dependent Cox Proportional Hazards model showed that female gender (HR=2.02), prior motion sickness history (HR=2.22), and Mini-SSQ score (HR=1.55) were associated with dropout. There were no differences between dropouts and completers on any of the cognitive abilities tests. Older adults are a high-risk group for simulator sickness. Within this group, female gender and prior motion sickness history are related to simulator dropout. Higher reported experience of symptoms of simulator sickness increased rates of dropout. The results highlight the importance of screening and monitoring of participants in driving simulation studies. Older adults, females, and those with a prior history of motion sickness may be especially at risk. Copyright © 2015 Elsevier Ltd and National Safety Council. All rights reserved.

Leading during change: the effects of leader behavior on sickness absence in a Norwegian health trust.

2012-09-17

Organizational change often leads to negative employee outcomes such as increased absence. Because change is also often inevitable, it is important to know how these negative outcomes could be reduced. This study investigates how the line manager's behavior relates to sickness absence in a Norwegian health trust during major restructuring. Leader behavior was measured by questionnaire, where employees assessed their line manager's behavior (N = 1008; response rate 40%). Data on sickness absence were provided at department level (N = 35) and were measured at two times. Analyses were primarily conducted using linear regression; leader behavior was aggregated and weighted by department size. The results show a relationship between several leader behaviors and sickness absence. The line managers' display of loyalty to their superiors was related to higher sickness absence; whereas task monitoring was related to lower absence. Social support was related to higher sickness absence. However, the effect of social support was no longer significant when the line manager also displayed high levels of problem confrontation. The findings clearly support the line manager's importance for employee sickness absence during organizational change. We conclude that more awareness concerning the manager's role in change processes is needed.

Sick but yet at work. An empirical study of sickness presenteeism.

2000-07-01

The study is an empirical investigation of sickness presenteeism in relation to occupation, irreplaceability, ill health, sickness absenteeism, personal income, and slimmed down organisation. Cross sectional design. Swedish workforce. The study group comprised a stratified subsample of 3801 employed persons working at the time of the survey, interviewed by telephone in conjunction with Statistics Sweden's labour market surveys of August and September 1997. The response rate was 87 per cent. A third of the persons in the total material reported that they had gone to work two or more times during the preceding year despite the feeling that, in the light of their perceived state of health, they should have taken sick leave. The highest presenteeism is largely to be found in the care and welfare and education sectors (nursing and midwifery professionals, registered nurses, nursing home aides, compulsory school teachers and preschool/primary educationalists. All these groups work in sectors that have faced personnel cutbacks during the 1990s). The risk ratio (odds ratio (OR)) for sickness presenteeism in the group that has to re-do work remaining after a period of absence through sickness is 2.29 (95% CI 1.79, 2.93). High proportions of persons with upper back/neck pain and fatigue/slightly depressed are among those with high presenteeism (p< 0.001). Occupational groups with high sickness presenteeism show high sickness absenteeism (rho = 0. 38; p<.01) and the hypothesis on level of pay and sickness presenteeism is also supported (rho = -0.22; p<0.01). Members of occupational groups whose everyday tasks are to provide care or welfare services, or teach or instruct, have a substantially increased risk of being at work when sick. The link between difficulties in replacement or finding a stand in and sickness presenteeism is confirmed by study results. The categories with high sickness presenteeism experience symptoms more often than those without presenteeism. The most common combination is low monthly income, high sickness absenteeism and high sickness presenteeism.

The purpose of this study was to assess the effects of early part-time sick leave on return to work (RTW) and sickness absence among patients with musculoskeletal disorders. A randomized controlled trial was conducted in six occupational health units of medium- and large-size enterprises. Patients aged 18-60 years with musculoskeletal disorders (N=63) unable to perform their regular work were randomly allocated to part- or full-time sick leave. In the former group, workload was reduced by restricting work time by about a half. Remaining work tasks were modified when necessary, as specified in a "fit note" from the physician. The main outcomes were time to return to regular work activities and sickness absence during 12-month follow-up. Time to RTW sustained for ≥4 weeks was shorter in the intervention group (median 12 versus 20 days, P=0.10). Hazard ratio of RTW adjusted for age was 1.60 [95% confidence interval (95% CI) 0.98-2.63] and 1.76 (95% CI 1.21-2.56) after further adjustment for pain interference with sleep and previous sickness absence at baseline. Total sickness absence during the 12-month follow-up was about 20% lower in the intervention than the control group. Compliance with the intervention was high with no discontinuations of part-time sick leave due to musculoskeletal reasons. Early part-time sick leave may provide a faster and more sustainable return to regular duties than full-time sick leave among patients with musculoskeletal disorders. This is the first study to show that work participation can be safely increased with early part-time sick leave.

Severe motion sickness is a huge obstacle for people conducting precise aviation, marine or emergency service tasks. The combination of scopolamine and d-amphetamine is most effective in preventing severe motion sickness. However, this combination is not included in any present pharmacopoeia due to the abuse liability of d-amphetamine. We wanted to find a combination to replace it for the treatment of severe motion sickness. We compared the efficacy of scopolamine, diphenhydramine, and granisetron (representing three classes of drugs) with different doses, and found that scopolamine was the most effective one. We also found scopolamine inhibited central nervous system at therapeutic doses and caused anxiety. Then, we combined it with different doses of psychostimulants (d-amphetamine, modafinil, caffeine) to find the best combination for motion sickness. The efficacy of scopolamine with modafinil (1 + 10 mg/kg) was equivalent to that of scopolamine with d-amphetamine (1 + 1 mg/kg); This combination also excited central nervous system and abolished the anxiety caused by scopolamine. The optimal dose ratio of scopolamine and modafinil is 1:10. This combination is beneficial for motion sickness and can abolish the side effects of scopolamine. So, it might be a good replacement of scopolamine and d-amphetamine for severe motion sickness. © 2016 John Wiley & Sons Ltd.

Methods Leader behavior was measured by questionnaire, where employees assessed their line manager’s behavior (N = 1008; response rate 40%). Data on sickness absence were provided at department level (N = 35) and were measured at two times. Analyses were primarily conducted using linear regression; leader behavior was aggregated and weighted by department size. Results The results show a relationship between several leader behaviors and sickness absence. The line managers’ display of loyalty to their superiors was related to higher sickness absence; whereas task monitoring was related to lower absence. Social support was related to higher sickness absence. However, the effect of social support was no longer significant when the line manager also displayed high levels of problem confrontation. Conclusions The findings clearly support the line manager’s importance for employee sickness absence during organizational change. We conclude that more awareness concerning the manager’s role in change processes is needed. PMID:22984817

A task force for the American Society for Surgery of the Hand (ASSH) recently investigated the practice patterns, board certification, subspecialty certification status, and ASSH membership of hand surgeons after completion of fellowship training. A total of 37% of the fellowship graduates from 2000 to 2006 had not attained subspecialty certification for a variety of reasons. A smaller group of fellowship graduates obtained the subspecialty certification but had not become Active Members of the ASSH. Efforts to strengthen the hand surgeon community and best serve our patients should focus on evolving patterns in post fellowship choices that reflect practice type choices and generational changes.

A heuristic mathematical model for the dynamics of sensory conflict and motion sickness

NASA Technical Reports Server (NTRS)

Oman, C. M.

1982-01-01

The etiology of motion sickness is now usually explained in terms of a qualitatively formulated sensory conflict hypothesis. By consideration of the information processing task faced by the central nervous system in estimating body spatial orientation and in controlling active body movement using an internal model referenced control strategy, a mathematical model for sensory conflict generation is developed. The model postulates a major dynamic functional role for sensory conflict signals in movement control, as well as in sensory motor adaptation. It accounts for the role of active movement in creating motion sickness symptoms in some experimental circumstances, and in alleviating them in others. The relationship between motion sickness produced by sensory rearrangement and that resulting from external motion disturbances is explicitly defined. A nonlinear conflict averaging model describes dynamic aspects of experimentally observed subjective discomfort sensation, and suggests resulting behavior.

Relation between sick leave and selected exposure variables among women semiconductor workers in Malaysia

PubMed Central

Chee, H; Rampal, K

2003-01-01

Aims: To determine the relation between sick leave and selected exposure variables among women semiconductor workers. Methods: This was a cross sectional survey of production workers from 18 semiconductor factories. Those selected had to be women, direct production operators up to the level of line leader, and Malaysian citizens. Sick leave and exposure to physical and chemical hazards were determined by self reporting. Three sick leave variables were used; number of sick leave days taken in the past year was the variable of interest in logistic regression models where the effects of age, marital status, work task, work schedule, work section, and duration of work in factory and work section were also explored. Results: Marital status was strongly linked to the taking of sick leave. Age, work schedule, and duration of work in the factory were significant confounders only in certain cases. After adjusting for these confounders, chemical and physical exposures, with the exception of poor ventilation and smelling chemicals, showed no significant relation to the taking of sick leave within the past year. Work section was a good predictor for taking sick leave, as wafer polishing workers faced higher odds of taking sick leave for each of the three cut off points of seven days, three days, and not at all, while parts assembly workers also faced significantly higher odds of taking sick leave. Conclusion: In Malaysia, the wafer fabrication factories only carry out a limited portion of the work processes, in particular, wafer polishing and the processes immediately prior to and following it. This study, in showing higher illness rates for workers in wafer polishing compared to semiconductor assembly, has implications for the governmental policy of encouraging the setting up of wafer fabrication plants with the full range of work processes.

2010-01-01

To compare the length of nonwork-related sick leave among cases managed by an insurance company versus those managed by the National Institute of Social Security (NISS). We performed a retrospective cohort study of 289,686 cases of sick leave lasting for more than 15 days that began in 2005 after certification by a primary care physician in Catalonia, were reported to the Catalonian Institute of Medical Evaluations, and were followed to term. Of the total, 156,676 cases were managed by the NISS. To account for repeat episodes (approximately 25% of the total), the Wang-Chang estimator was used to calculate the median duration and percentiles; comparisons were made using log-logistic regression with shared gamma frailty models, with calculation of time ratios (TR) and their corresponding 95% confidence intervals (95% CI). The median duration of sick leave was 43 days for cases managed by the NISS and 39 days for those managed by the insurance company. This difference was statistically significant both for men employed under contract (TR=0.87; 95% CI: 0.85-0.88) and for those who were self-employed (TR=0.78; 95% CI: 0.75-0.80) as well as for women under contract (TR=0.85; 95% CI: 0.84-0.87) and self-employed women (TR=0.84; 95% CI: 0.81-0.88). These differences persisted after adjustment was performed for age and health region. For sick leave lasting more than 15 days, these results confirm that cases managed by an insurance company ended earlier than for those managed by the NISS, both for contract and self-employed workers. Further research is needed to explore the reasons for these differences. Copyright 2009 SESPAS. Published by Elsevier Espana. All rights reserved.

Perceptions of health professionals towards the management of back pain in the context of work: a qualitative study

PubMed Central

2014-01-01

Background Musculoskeletal complaints have a significant impact on work in terms of reduced productivity, sickness absence and long term incapacity for work. This study sought to explore GPs’ and physiotherapists’ perceptions of sickness certification in patients with musculoskeletal problems. Methods Eleven (11) GPs were sampled from an existing general practice survey, and six (6) physiotherapists were selected randomly using ‘snowball’ sampling techniques, through established contacts in local physiotherapy departments. Semi-structured qualitative interviews were conducted with respondents lasting up to 30 minutes. The interviews were audio recorded and transcribed verbatim, following which they were coded using N-Vivo qualitative software and analysed thematically using the constant comparative methodology, where themes were identified and contrasted between and within both groups of respondents. Results Three themes were identified from the analysis: 1) Approaches to evaluating patients’ work problems 2) Perceived ability to manage ‘work and pain’, and 3) Policies and penalties in the work-place. First, physiotherapists routinely asked patients about their job and work difficulties using a structured (protocol-driven) approach, whilst GPs rarely used such structured measures and were less likely to enquire about patients’ work situation. Second, return to work assessments revealed a tension between GPs’ gatekeeper and patient advocacy roles, often resolved in favour of patients’ concerns and needs. Some physiotherapists perceived that GPs’ decisions could be influenced by patients’ demand for a sick certificate and their close relationship with patients made them vulnerable to manipulation. Third, the workplace was considered to be a specific source of strain for patients acting as a barrier to work resumption, and over which GPs and physiotherapists could exercise only limited control. Conclusion We conclude that healthcare professionals need to take account of patients’ work difficulties, their own perceived ability to offer effective guidance, and consider the ‘receptivity’ of employment contexts to patients’ work problems, in order to ensure a smooth transition back to work.

2016-02-01

The successful enactment of mandatory pharmacy technician certification in Kansas is described. In 2004, Kansas began requiring registration of all pharmacy technicians with the state board of pharmacy. Registration identified individuals working as pharmacy technicians but did not require any specific education or certification. In September 2012, the Kansas Board of Pharmacy created a task force of key stakeholders including pharmacists from multiple areas of practice, the University of Kansas School of Pharmacy, organizational leaders from the Kansas Council of Health-System Pharmacists (KCHP) and Kansas Pharmacists Association, and professional lobbyists. The goals of this task force were to research practices of technician certification in other states and to make recommendations to the state board of pharmacy on how Kansas could accomplish mandatory technician certification. The task force outlined the steps needed to achieve legislation that could be supported by the members. These topics included the creation of a technician trainee category, grandfathering certain technicians who had been practicing for a designated period of time, state board-approved exemptions, training requirements, age and education requirements, continuing-education requirements, and pharmacist:technician ratio. The recommendations were finalized at the August 2013 Kansas Pharmacy Summit, and the proposed legislation was introduced and passed during the 2014 legislative session. KCHP members learned many valuable lessons about advocacy and the legislative process with this initiative, including building relationships, working with legislators, and working with other professional organizations. The formation of a task force led to the successful passage of a bill granting the Kansas Board of Pharmacy the authority to issue regulations regarding mandatory pharmacy technician certification.

Increase in sickness absence with psychiatric diagnosis in Norway: a general population-based epidemiologic study of age, gender and regional distribution

PubMed Central

Hensing, Gunnel; Andersson, Lena; Brage, Sören

2006-01-01

Background The aim of this study was to assess the incidence of sickness absence with psychiatric diagnoses from 1994–2000, and the distribution across gender, age groups, diagnostic groups and regions in a general population. Methods The population at risk was defined as all individuals aged 16–66 years who were entitled to sickness benefits in 1994, 1996, 1998 and 2000 (n = 2,282,761 in 2000). All individuals with a full-time disability pension were excluded. The study included approximately 77% of the Norwegian population aged 16–66 years. For each year, the study base started on 1 January and ended on 31 December. Individuals that were sick-listed for more than 14/16 consecutive days with a psychiatric diagnosis on their medical certificate were selected as cases. Included in this study were data for Norway, the capital city Oslo and five regions in the southeast of the country. Results Sickness absence with psychiatric diagnoses increased in all age groups, in women and men, and in all regions. At the national level, the cumulative incidence increased in women from 1.7% in 1994 to 4.6% in 2000, and in men from 0.8% in 1994 to 2.2% in 2000. The highest cumulative incidence was found in middle-aged women and men (30–59 years). Women had a higher incidence than men in all stratification groups. The cumulative incidences in 2000 varied between 4.6% to 5.6% in women in the different regions, and for men the corresponding figures were 2.1% to 3.2%. Throughout the four years studied, women in Oslo had more than twice as high incidence levels of sickness absence with alcohol and drug diagnoses as the country as a whole. There were some differences between regions in sickness absence with specific psychiatric diagnoses, but they were small and most comparisons were non-significant. Conclusion Sickness absence with psychiatric diagnoses increased between 1994 and 2000 in Norway. The increase was highest in the middle-aged, and in women. Few regional differences were found. That the increase pervaded all stratification groups supports general explanations of the increase, such as changes in attitudes to psychiatric disorders in both patients and doctors, and increased mental distress probably associated with societal changes at a more structural level.

Self-driving carsickness.

PubMed

Diels, Cyriel; Bos, Jelte E

2016-03-01

This paper discusses the predicted increase in the occurrence and severity of motion sickness in self-driving cars. Self-driving cars have the potential to lead to significant benefits. From the driver's perspective, the direct benefits of this technology are considered increased comfort and productivity. However, we here show that the envisaged scenarios all lead to an increased risk of motion sickness. As such, the benefits this technology is assumed to bring may not be capitalised on, in particular by those already susceptible to motion sickness. This can negatively affect user acceptance and uptake and, in turn, limit the potential socioeconomic benefits that this emerging technology may provide. Following a discussion on the causes of motion sickness in the context of self-driving cars, we present guidelines to steer the design and development of automated vehicle technologies. The aim is to limit or avoid the impact of motion sickness and ultimately promote the uptake of self-driving cars. Attention is also given to less well known consequences of motion sickness, in particular negative aftereffects such as postural instability, and detrimental effects on task performance and how this may impact the use and design of self-driving cars. We conclude that basic perceptual mechanisms need to be considered in the design process whereby self-driving cars cannot simply be thought of as living rooms, offices, or entertainment venues on wheels.

Jones, Sherrie; Kennedy, Robert; Harm, Deborah

1992-01-01

When independent stimuli are available for accommodation, as in the dark or under low contrast conditions, the lens seeks its resting position. Individual differences in resting positions are reliable, under autonomic control, and can change with visual task demands. We hypothesized that motion sickness in a flight simulator might result in dark focus changes. Method: Subjects received training flights in three different Navy flight simulators. Two were helicopter simulators entailed CRT presentation using infinity optics, one involved a dome presentation of a computer graphic visual projection system. Results: In all three experiments there were significant differences between dark focus activity before and after simulator exposure when comparisons were made between sick and not-sick pilot subjects. In two of these experiments, the average shift in dark focus for the sick subjects was toward increased myopia when each subject was compared to his own baseline. In the third experiment, the group showed an average shift outward of small amount and the subjects who were sick showed significantly less outward movement than those who were symptom free. Conclusions: Although the relationship is not a simple one, dark focus changes in simulator sickness imply parasympathetic activity. Because changes can occur in relation to endogenous and exogenous events, such measurement may have useful applications as dependent measures in studies of visually coupled systems, virtual reality systems, and space adaptation syndrome.

Sickness absence among health workers in belo horizonte, brazil.

To describe the prevalence of sickness absence and to analyze factors associated with the outcome according to gender in a sample of healthcare workers at the Belo Horizonte Health Department. This study was based on a Belo Horizonte Health Department survey carried out between September 2008 and January 2009. From a randomly selected sample of 2,205 workers, 1,808 agreed to participate. Workers were classified into Health Staff or Health Care. Other explanatory variables were social and demographic data, work characteristics, and personal health. The Poisson regression was applied to analyze factors associated with sickness absence by the prevalence ratio (PR). The overall prevalence of sickness absence was 31.5% (23.8% for men and 34.6% for women). In the final model, we found higher rates of sickness absence in both male and female workers involved in tasks with high psychosocial demands (PR=1.86 men; PR=1.38 women) and in those that reported using medication for treating chronic diseases (PR=1.96 men; PR=1.50 women). Women having a permanent job contract had a higher prevalence of sickness absence than those having a temporary job contract (PR=1.71). Our findings suggest a paradox in how healthcare is organized: good results in terms of its global objective of providing healthcare for citizens contrast with lack of effective measures for protecting healthcare workers.

Due to low employment rates associated to chronic conditions in Europe, it is essential to foster effective integration and re-integration into work strategies. The objective of this systematic review is to summarize the evidence on the effectiveness of strategies for integration and re-integration to work for persons with chronic diseases or with musculoskeletal disorders, implemented in Europe in the past five years. A systematic search was conducted in MedLine, PsycINFO, CDR-HTA, CDR-DARE and Cochrane Systematic Reviews. Overall, 32 relevant publications were identified. Of these, 21 were considered eligible after a methodological assessment and included. Positive changes in employment status, return to work and sick leave outcomes were achieved with graded sickness-absence certificates, part-time sick leave, early ergonomic interventions for back pain, disability evaluation followed by information and advice, and with multidisciplinary, coordinated and tailored return to work interventions. Additionally, a positive association between the co-existence of active labour market policies to promote employment and passive support measures (e.g., pensions or benefits) and the probability of finding a job was observed. Research on the evaluation of the effectiveness of strategies targeting integration and re-integration into work for persons with chronic health conditions needs, however, to be improved and strengthened.

The Growing Costs and Burden of Family Caregiving of Older Adults: A Review of Paid Sick Leave and Family Leave Policies.

PubMed

Chen, Mei-Lan

2016-06-01

Many family caregivers of older adults suffer from a high burden of care and struggle with the balance of jobs and caregiving tasks. However, the United States is the only developed country without paid sick leave policies for all workers and their families. The purpose of this article is to review the federal Family and Medical Leave Act (FMLA) and empirical studies about paid sick policy, propose policy recommendations, and provide a starting point for future research. The result has shown that the FMLA only applies to certain employees and the provided leave is unpaid under the act. Working women, Latinos, low-wage workers, and less-educated employees are less likely to access paid sick leave and family leave. Obviously, social injustice exists in the FMLA and paid sick leave policies. This article proposes that the Family and Medical Leave Act coverage should be expanded to protect all workers, especially for primary family caregivers of older adults, regardless of family relationships. Also, paid sick and family leave laws should be passed, and requirements to contribute to a family-friendly workplace added to relieve the growing burden of family caregiving of older adults. Policy recommendations including the exemplar of the San Francisco Paid Sick Leave Ordinance, and suggestions for more comprehensive policies are proposed for federal, state, or/and city legislation. © The Author 2014.

Job mismatching, unequal opportunities and long-term sickness absence in female white-collar workers in Sweden.

PubMed

Sandmark, Hélène

2009-01-01

To investigate associations between long-term sick-listing and factors at work and in family life. Associations were investigated in a cross-sectional case-referent study. The study base included women in white-collar jobs, aged 30-55 years, living in three urban areas in Sweden between February 2004 and October 2004. A postal questionnaire was constructed with questions on occupational and family circumstances, and sent to 513 randomly selected female white-collar workers, of whom 233 had ongoing sick-leave of 90 days or more. The response rate was 81% (n = 413). Most of the women in this study were in managerial positions. The unadjusted associations showed that sick-listed women with children showed the highest estimates regarding reported long working hours, bullying, high mental strain, low control and low influence at work, and work-family imbalance. In a regression model, the strongest associations were: experiencing too high mental strain in work tasks (odds ratio (OR) = 2.57, 95% confidence interval (CI) = 2.09-3.15) and low control and influence at work (OR=2.17, 95% CI= 1.60-2.94). Sick-listed women reported an overall higher dissatisfaction with their workplace and working life. There seems to be a greater tendency for the sick-listed women in this study to experience low control and too high mental strain at work and to live in traditional family relationships with unequal opportunities. The women who were sick-listed were probably less able to cope with work stress and to find a balance between work and family life.

Huber, Tobias; Paschold, Markus; Hansen, Christian; Wunderling, Tom; Lang, Hauke; Kneist, Werner

2017-11-01

Virtual reality (VR) and head mount displays (HMDs) have been advanced for multimedia and information technologies but have scarcely been used in surgical training. Motion sickness and individual psychological changes have been associated with VR. The goal was to observe first experiences and performance scores using a new combined highly immersive virtual reality (IVR) laparoscopy setup. During the study, 10 members of the surgical department performed three tasks (fine dissection, peg transfer, and cholecystectomy) on a VR simulator. We then combined a VR HMD with the VR laparoscopic simulator and displayed the simulation on a 360° video of a laparoscopic operation to create an IVR laparoscopic simulation. The tasks were then repeated. Validated questionnaires on immersion and motion sickness were used for the study. Participants' times for fine dissection were significantly longer during the IVR session (regular: 86.51 s [62.57 s; 119.62 s] vs. IVR: 112.35 s [82.08 s; 179.40 s]; p = 0.022). The cholecystectomy task had higher error rates during IVR. Motion sickness did not occur at any time for any participant. Participants experienced a high level of exhilaration, rarely thought about others in the room, and had a high impression of presence in the generated IVR world. This is the first clinical and technical feasibility study using the full IVR laparoscopy setup combined with the latest laparoscopic simulator in a 360° surrounding. Participants were exhilarated by the high level of immersion. The setup enables a completely new generation of surgical training.

A theoretical framework to describe communication processes during medical disability assessment interviews

PubMed Central

van Rijssen, H Jolanda; Schellart, Antonius JM; Anema, Johannes R; van der Beek, Allard J

2009-01-01

Background Research in different fields of medicine suggests that communication is important in physician-patient encounters and influences satisfaction with these encounters. It is argued that this also applies to the non-curative tasks that physicians perform, such as sickness certification and medical disability assessments. However, there is no conceptualised theoretical framework that can be used to describe intentions with regard to communication behaviour, communication behaviour itself, and satisfaction with communication behaviour in a medical disability assessment context. Objective The objective of this paper is to describe the conceptualisation of a model for the communication behaviour of physicians performing medical disability assessments in a social insurance context and of their claimants, in face-to-face encounters during medical disability assessment interviews and the preparation thereof. Conceptualisation The behavioural model, based on the Theory of Planned Behaviour (TPB), is conceptualised for the communication behaviour of social insurance physicians and claimants separately, but also combined during the assessment interview. Other important concepts in the model are the evaluation of communication behaviour (satisfaction), intentions, attitudes, skills, and barriers for communication. Conclusion The conceptualisation of the TPB-based behavioural model will help to provide insight into the communication behaviour of social insurance physicians and claimants during disability assessment interviews. After empirical testing of the relationships in the model, it can be used in other studies to obtain more insight into communication behaviour in non-curative medicine, and it could help social insurance physicians to adapt their communication behaviour to their task when performing disability assessments.

[Sick leave among workers employed in restructured enterprise].

PubMed

Szubert, Zuzanna; Sobala, Wojciech

2003-01-01

Ownership and restructuring transformations that are taking now place in Poland, as well as the situation on the labor market have their impact on the indicators, which illustrate the workers' health situation, including temporary work disability preceding the issue of the certification granting the disability pension. The aim of this analysis was to identify the changes in the extent and causes of sickness absence among workers after restructuring. The study was carried out in one of the largest transport industry enterprises during the years of its restructuring (1984-1994), covering 8588 workers, and after its restructuring (1997-1999), covering 2702 workers. Following the restructuring, the enterprise's staff was rejuvenated so that the number of workers aged over 50 years decreased by almost fifty percent. The analysis was based on the sickness absence rate calculated as the ratio between the number of days of work disability in a given period of time and the number of person-days in the same period. In 1997-1999, a 33% decrease in sickness absence among women and a 25% decrease among men were observed in the study enterprise as compared with the period of 1989-1994. However, the enhanced absence was also found due to the following diseases: mental disorders (a threefold increase in men); diseases of the musculoskeletal system (by 54% in men and by 43% in women); endocrine, nutritional and metabolic diseases and immunity disorders (a threefold increase in women). Following the restructuring, considerable changes in the sickness absence structure, by causes of diseases, were revealed. A substantial decrease in the share of male and female absence due to diseases of the respiratory and circulatory systems and almost threefold decrease in complications of pregnancy, childbirth and the puerperium in women were noted. In addition, over twofold increase in male and female sickness absence due to diseases of the musculoskeletal system, and lower but significant increase due to mental pathologies (from 3 to 12% in males and from 4 to 7% in women) were recorded. The changes observed in sickness absence result mainly from the changes in the magnitude and structure of employment in the restructured enterprise and related organizational modifications, which arise stressogenic situations among workers, more intensified at risk of unemployment.

NASA Technical Reports Server (NTRS)

Oman, C. M.

1982-01-01

By consideration of the information processing task faced by the central nervous system in estimating body spatial orientation and in controlling active body movement using an internal model referenced control strategy, a mathematical model for sensory conflict generation is developed. The model postulates a major dynamic functional role for sensory conflict signals in movement control, as well as in sensory-motor adaptation. It accounts for the role of active movement in creating motion sickness symptoms in some experimental circumstance, and in alleviating them in others. The relationship between motion sickness produced by sensory rearrangement and that resulting from external motion disturbances is explicitly defined. A nonlinear conflict averaging model is proposed which describes dynamic aspects of experimentally observed subjective discomfort sensation, and suggests resulting behaviours. The model admits several possibilities for adaptive mechanisms which do not involve internal model updating. Further systematic efforts to experimentally refine and validate the model are indicated.

Ratino, D. A.; Repperger, D. W.; Goodyear, C.; Potor, G.; Rodriguez, L. E.

1988-01-01

A microprocessor-based test battery containing simple reaction time, choice reaction time, and time perception tasks was flown aboard a 1985 Space Shuttle flight. Data were obtained from four crew members. Individual subject means indicate a correlation between change in reaction time during the flight and the presence of space motion sickness symptoms. The time perception task results indicate that the shortest duration task time (2 s) is progressively overestimated as the mission proceeds and is statistically significant when comparing preflight and postflight baselines. The tasks that required longer periods of time to estimate (8, 12, and 16 s) are less affected.

In 2011, an oncology nurse navigator (ONN) role delineation survey (RDS) was conducted by the Oncology Nursing Society (ONS) when the role was relatively new to oncology. Results did not demonstrate a unique skill set for the ONN; however, since then, the role has expanded. ONS and the Oncology Nursing Certification Corporation partnered in 2016 to complete an RDS of ONNs to redefine the role and determine the need for an ONN certification examination. A structured RDS was conducted using a formal consensus-building process. A survey was developed and released to examine the specific tasks, knowledge, and skills for the ONN as well as to determine which role possesses more responsibility for the tasks. The ONN role is evolving, and more was learned about its key tasks, including differences in the responsibilities of the ONN and the clinical or staff nurse. However, the RDS did not find an adequate difference in the knowledge required by the ONN and the clinical or staff nurse to support the need for a separate ONN certification.

Using a multilevel mediation model to examine the effects of National Board Certified Teachers on high school science students' cognitive engagement

NASA Astrophysics Data System (ADS)

Zaleski, Diana Janet

2011-12-01

The National Board for Professional Teaching Standards claims to identify effective educators through their certification process. However, research concerning National Board Certified Teachers (NBCT) is inconclusive. The purpose of this study was to examine the direct and indirect effects of NBCT on the cognitive engagement of high school science students. Multilevel mediation modeling was used to examine the direct and indirect effects of teacher certification on students' cognitive engagement in science and whether students' expectancies for success and perceptions of task value mediate these effects. Students of NBCT were found to be more cognitively engaged in science than students of non-NBCT; however, students' expectancies for success and perceptions of task value did not mediate this relationship. In addition, students with more positive expectancies for success and perceptions of task value were more cognitively engaged in science. These findings support the proposition that the National Board certification process at least identifies effective educators.

1992-08-01

Sustained exposure to high terrestrial altitudes is associated with cognitive decrement, mood changes, and acute mountain sickness (AMS). Such impairment in aviators could be a safety hazard. Thirteen male soldiers, ages 19-24, ascended in 10 min from sea level to 4,300 m (simulated), and remained there 2.5 d. Four times per day, subjects completed a test battery consisting of nine cognitive tests, a mood scale, and an AMS questionnaire. During one test session per day, subjects breathed 35% oxygen instead of ambient air. Analysis revealed transient deficits on altitude day 1 for three cognitive tasks. Most tasks displayed a persistent training effect. Sick subjects' moods were more negative and their performance improvement less. On altitude day 1, oxygen administration improved performance on two cognitive tests and one mood subscale. Following rapid ascent to 4,300 m, performance is most affected during the first 8 h. Individuals affected by AMS tend to improve more slowly in performance and have more negative moods than those who feel well.

To quantify the variation in rates of absence due to musculoskeletal pain across 47 occupational groups (mostly nurses and office workers) from 18 countries, and to explore personal and group-level risk factors that might explain observed differences. A standardised questionnaire was used to obtain information about musculoskeletal pain, sickness absence and possible risk factors in a cross-sectional survey of 12 416 workers (92-1017 per occupational group). Additionally, group-level data on socioeconomic variables, such as sick pay and unemployment rates, were assembled by members of the study team in each country. Associations of sickness absence with risk factors were examined by Poisson regression. Overall, there were more than 30-fold differences between occupational groups in the 12-month prevalence of prolonged musculoskeletal sickness absence, and even among office workers carrying out similar occupational tasks, the variation was more than tenfold. Personal risk factors included older age, lower educational level, tendency to somatise, physical loading at work and prolonged absence for non-musculoskeletal illness. However, these explained little of the variation between occupational groups. After adjustment for individual characteristics, prolonged musculoskeletal sickness absence was more frequent in groups with greater time pressure at work, lower job control and more adverse beliefs about the work-relatedness of musculoskeletal disorders. Musculoskeletal sickness absence might be reduced by eliminating excessive time pressures in work, maximising employees' responsibility and control and providing flexibility of duties for those with disabling symptoms. Care should be taken not to overstate work as a cause of musculoskeletal injury.

An Empirical Evaluation of Automated Theorem Provers in Software Certification

2004-01-01

We describe a system for the automated certification of safety properties of NASA software. The system uses Hoare-style program verification technology to generate proof obligations which are then processed by an automated first-order theorem prover (ATP). We discuss the unique requirements this application places on the ATPs, focusing on automation, proof checking, and usability. For full automation, however, the obligations must be aggressively preprocessed and simplified, and we demonstrate how the individual simplification stages, which are implemented by rewriting, influence the ability of the ATPs to solve the proof tasks. Our results are based on 13 certification experiments that lead to more than 25,000 proof tasks which have each been attempted by Vampire, Spass, e-setheo, and Otter. The proofs found by Otter have been proof-checked by IVY.

Use of promethazine to hasten adaptation to provocative motion

NASA Technical Reports Server (NTRS)

Lackner, J. R.; Graybiel, A.

1994-01-01

In an earlier study, the authors found that severely motion sick individuals could be greatly relieved of their symptoms by intramuscular injections of promethazine (50 mg) or scopolamine (.5 mg). Comparable 50-mg injections of promethazine also have been found effective in alleviating symptoms of space motion sickness. The concern has risen, however, that such drugs may delay or retard the acquisition of adaptation to stressful environments. In the current study, we controlled arousal using a mental arithmetic task and precisely equated the exposure history (number of head movements during rotation) of a placebo, control group and an experimental group who had received promethazine. No differences in total adaptation or in rates of adaptation were present between the two groups. Another experimental group also received promethazine and was allowed to make as many head movements as they could, before reaching nausea, up to 800. This group showed a greater level of adaptation than the placebo group. These results suggest a strategy for dealing with space motion sickness that is described.

Preflight Adaptation Training for Spatial Orientation and Space Motion Sickness

Harm, Deborah L.; Parker, Donald E.

1994-01-01

Two part-task preflight adaptation trainers (PATs) are being developed at the NASA Johnson Space Center to preadapt astronauts to novel sensory stimulus conditions similar to those present in microgravity to facilitate adaptation to microgravity and readaptation to Earth. This activity is a major component of a general effort to develop countermeasures aimed at minimizing sensory and sensorimotor disturbances and Space Motion Sickness (SMS) associated with adaptation to microgravity and readaptation to Earth. Design principles for the development of the two trainers are discussed, along with a detailed description of both devices. In addition, a summary of four ground-based investigations using one of the trainers to determine the extent to which various novel sensory stimulus conditions produce changes in compensatory eye movement responses, postural equilibrium, motion sickness symptoms, and electrogastric responses are presented. Finally, a brief description of the general concept of dual-adopted states that underly the development of the PATs, and ongoing and future operational and basic research activities are presented.

Do patients with psychogenic nonepileptic seizures have positive covert attitudes toward sickness?

PubMed

Testa, S Marc; Brandt, Jason

2010-11-01

Some individuals with psychogenic nonepileptic seizures (PNES) are seen as having adopted a "sick role" that relinquishes them of responsibility for meeting stressful life demands. Thus, patients with PNES may have positive, albeit unrecognized, attitudes toward seizures, or perhaps illness in general. Because such covert attitudes may not be amendable to self-report, the current study used the Implicit Association Test (IAT), a methodology by which attitudes toward illness and disability can be inferred from performance on an ostensibly neutral task. Individuals with PNES did not have a reduced interference effect when responding to sickness-related and pleasant words on the same response key. Exploratory analyses revealed that a pronounced somatic focus and higher extraversion were associated with more neutral attitudes toward illness among patients with PNES. This IAT methodology found little support for the notion that patients with PNES harbor positive attitudes toward illness. Limitations of the IAT methodology are reviewed and recommendations are provided. Published by Elsevier Inc.

Influence of bone-conducted vibration on simulator sickness in virtual reality

PubMed Central

Moon, Jae; Troje, Nikolaus F.

2018-01-01

Use of virtual reality (VR) technology is often accompanied by a series of unwanted symptoms, including nausea and headache, which are characterised as ‘simulator sickness’. Sensory mismatch has been thought to lie at the heart of the problem and recent studies have shown that reducing cue mismatch in VR can have a therapeutic effect. Specifically, electrical stimulation of vestibular afferent nerves (galvanic vestibular stimulation; GVS) can reduce simulator sickness in VR. However, GVS poses a risk to certain populations and can also result in negative symptoms in normal, healthy individuals. Here, we tested whether noisy vestibular stimulation through bone-vibration can also reduce symptoms of simulator sickness. We carried out two experiments in which participants performed a spatial navigation task in VR and completed the Simulator Sickness Questionnaire over a series of trials. Experiment 1 was conducted using a high-end projection-based VR display, whereas Experiment 2 involved the use of a consumer head mounted display. During each trial, vestibular stimulation was either: 1) absent; 2) coupled with large angular accelerations of the projection camera; or 3) applied randomly throughout each trial. In half of the trials, participants actively navigated using a motion controller, and in the other half they were moved passively through the environment along pre-recorded motion trajectories. In both experiments we obtained lower simulator sickness scores when vestibular stimulation was coupled with angular accelerations of the camera. This effect was obtained for both active and passive movement control conditions, which did not differ. The results suggest that noisy vestibular stimulation can reduce simulator sickness, and that this effect appears to generalize across VR conditions. We propose further examination of this stimulation technique. PMID:29590147

2011-01-01

Virtual environments (VE) offer unique training opportunities, including training astronauts to preadapt them to the novel sensory conditions of microgravity. However, one unresolved issue with VE use is the occurrence of cybersickness during and following exposure to VE systems. Most individuals adapt and become less ill with repeated interaction with VEs. The goal of this investigation was to compare motion sickness symptoms (MSS) produced by dome and head-mounted (HMD) displays and to examine the effects of repeated exposures on MSS. Sixty-one subjects participated in the study. Three experimental sessions were performed each separated by one day. The subjects performed a navigation and pick and place task in either a dome or HMD VE. MSS were measured using a Simulator Sickness Questionnaire before, immediately after, and at 1, 2, 4 and 6 hours following exposure to the VEs. MSS data were normalized by calculating the natural log of each score and an analysis of variance was performed. We observed significant main effects for day and time and a significant day by time interaction for total sickness and for each of the subscales, nausea, oculomotor and disorientation. However, there was no significant main effect for device. In conclusion, subjects reported a large increase in MSS immediately following exposure to both the HMD and dome, followed by a rapid recovery across time. Sickness severity also decreased over days, which suggests that subjects become dual-adapted over time making VE training a viable pre-flight countermeasure for space motion sickness.

Reversing prisms are known to produce symptoms of motion sickness, and have been used to provide a chronic stimulus for training subjects on symptom recognition and regulation. However, testing procedures with reversing prisms have not been standardized. A set of procedures were evaluated which could be standardized using prisms for provocation and to compare the results between Right/Left Reversing Prisms (R/L-RP) and Up/Down Reversing Prisms (U/D-RP). Fifteen subjects were tested with both types of prisms using a self paced walking course throughout the laboratory with work stations established at specified intervals. The work stations provided tasks requiring eye-hand-foot coordination and various head movements. Comparisons were also made between these prism tests and two other standardized susceptibility tests, the KC-135 parabolic static chair test and the Staircase Velocity Motion Test (SVMT). Two different types of subjective symptom reports were compared. The R/L-RP were significantly more provocative than the U/D-RP. The incidence of motion sickness symptoms for the R/L-RP was similar to the KC-135 parabolic static chair test. Poor correlations were found between the prism tests and the other standardized susceptibility tests, which might indicate that different mechanisms are involved in provoking motion sickness for these different tests.

Autogenic-Feedback Training Exercise (AFTE) Mitigates the Effects of Spatial Disorientation to Simulated Orion Spacecraft Re-Entry: Individual Differences

2017-01-01

NASA has identified a potential risk of spatial disorientation to future astronauts during re-entry of the proposed Orion spacecraft. The purpose of this study was to determine if a 6-hour physiological training procedure, Autogenic-Feedback Training Exercise (AFTE), can mitigate these effects. Twenty subjects were assigned to two groups (AFTE and Control) matched for motion sickness susceptibility and gender. All subjects received a standard rotating chair test to determine motion sickness susceptibility; three training sessions on a manual performance task; and four exposures to a simulated Orion re-entry test in the rotating chair. Treatment subjects were given two hours of AFTE training before each Orion test. A diagnostic scale was used to evaluate motion sickness symptom severity. Results showed that 2 hours of AFTE significantly reduced motion sickness symptoms during the second Orion test. AFTE subjects were able to maintain lower heart rates and skin conductance levels and other responses than the control group subjects during subsequent tests. Trends show that performance was less degraded for AFTE subjects. The results of this study indicate that astronauts could benefit from receiving at least 2 hours of preflight AFTE. In addition, flight crews could benefit further by practicing physiologic self-regulation using mobile devices.

Objectives Sickness absence due to mental disease in the workplace has become a global public health problem. Previous studies report that sickness presenteeism is associated with sickness absence. We aimed to determine optimal cutoff scores for presenteeism in the screening of the future absences due to mental disease. Methods A prospective study of 2195 Japanese employees from all areas of Japan was conducted. Presenteeism and depression were measured by the validated Japanese version of the World Health Organization Health and Work Performance Questionnaire (WHO-HPQ) and K6 scale, respectively. Absence due to mental disease across a 2-year follow-up was surveyed using medical certificates obtained for work absence. Socioeconomic status was measured via a self-administered questionnaire. Receiver operating curve (ROC) analysis was used to determine optimal cutoff scores for absolute and relative presenteeism in relation to the area under the curve (AUC), sensitivity, and specificity. Results The AUC values for absolute and relative presenteeism were 0.708 (95% CI, 0.618–0.797) and 0.646 (95% CI, 0.546–0.746), respectively. Optimal cutoff scores of absolute and relative presenteeism were 40 and 0.8, respectively. With multivariate adjustment, cohort participants with our proposal cutoff scores for absolute and relative presenteeism were significantly more likely to be absent due to mental disease (OR = 4.85, 95% CI: 2.20–10.73 and OR = 5.37, 95% CI: 2.42–11.93, respectively). The inclusion or exclusion of depressive symptoms (K6≥13) at baseline in the multivariate adjustment did not influence the results. Conclusions Our proposed optimal cutoff scores of absolute and relative presenteeism are 40 and 0.8, respectively. Participants who scored worse than the cutoff scores for presenteeism were significantly more likely to be absent in future because of mental disease. Our findings suggest that the utility of presenteeism in the screening of sickness absence due to mental disease would help prevent such an absence. PMID:25340520

2017-01-01

The aim of the present study was to explore the potential differences between female and male professional divers with regards to demographics, diving certificates, areas of diving, diving activity and health effects. The Norwegian Labour Inspection Authority's Diving certificate register contains data on all professional inshore divers who have held a certificate at any time since 1980. Forty nine per cent of these divers responded to the "Norwegian diver 2011" questionnaire. Of these divers 64 female and 1327 male divers completed the questionnaire about their professional diving career, certificate, year of onset and the year they stopped diving professionally if they were not still active in the diving industry. The level of general education was higher among female divers. More males than females were fully certified in diving. The mean age was lower among female than male fully certified divers. Fully certified female divers reported a lower total number of dives, shallower dives and diving for a shorter period of time than the male divers. They also had a lower percentage of work within the quay/construction sector and more often worked as teachers/instructors. A lower percentage of fully certified females than males had experienced decompression sickness (16.7% vs. 26.9%). Life-threatening events and psychologically challenging events were less common among females, as were adverse health effects. No such gender differences were seen for divers with a restricted certificate. The fully certified, female professional divers in our study had a very short diving career, reported fewer and shallower dives, and chose less physically demanding jobs than their male counterparts. They also had a higher level of education, reported less health problems and a better quality of life. The health effects seem to be related to the type of work rather than to gender.

Non-Pharmacological Countermeasure to Decrease Landing Sickness and Improve Functional Performance

Upon return from long-duration spaceflight, 100% of crewmembers experience motion sickness (MS) symptoms. The interactions between crewmembers' adaptation to a gravitational transition, the performance decrements resulting from MS and/or use of promethazine (PMZ), and the constraints imposed by mission task demands could significantly challenge and limit an astronaut's ability to perform functional tasks during gravitational transitions. Stochastic resonance (SR) is "noise benefit": adding noise to a system might increase the information (examples to the left and above). Stochastic vestibular stimulation (SVS), or low levels of noise applied to the vestibular system, improves balance and locomotor performance (Goel et al. 2015, Mulavara et al. 2011, 2015). In hemi-lesioned rat models, Samoudi et al. 2012 found that SVS increased GABA release on the lesioned, but not the intact side. Activation of the GABA pathway is important in modulating MS and promoting adaptability (Cohen 2008) and was seen to reverse MS symptoms in rats after unilateral labyrinthectomy (Magnusson et al. 2000). Thus, SVS could be used to promote GABA pathways to reduce MS and promote adaptability, eliminate the need for PMZ or other performance-inhibiting drugs.

There are clear exemptions in Islam from fasting in Ramadan during sickness, pregnancy, and breastfeeding. Yet, some Muslim women still elect to fast while sick, pregnant, or breastfeeding because of a confluence of social, religious, and cultural factors. Little is known about the physiological effects of fasting during Ramadan on the mother or her unborn baby, and thus nurses and other healthcare providers are faced with the difficult task of providing appropriate medical advice to Muslim women regarding the safety and impact of their fasting. This article describes what is known about this topic and suggests that healthcare professionals learn as much as possible about the multicultural best practices and research-driven information about fasting in order to help Muslim women make informed decisions.

Construct validity of virtual laparoscopic simulators for basic laparoscopic skills has been proposed; however, it is not yet clear whether the simulators can identify the actual experience of surgeons in more complex procedures such as laparoscopic Roux-en-Y gastric bypass. This study tested the ability of the Lap Mentor simulator to recognize the experience in advanced laparoscopic procedures and to assess its role in the certification of bariatric surgeons. Twenty surgeons were divided into two groups according to their experience in laparoscopic and bariatric surgery. The general group included 10 general surgeons performing between 75 and 100 nonbariatric laparoscopic procedures. The bariatric group included 10 bariatric surgeons performing between 50 and 100 laparoscopic bariatric procedures. Participants were tested on the simulator in one basic task (task 1: eye-hand coordination) and in two tasks of the gastric bypass module (task 2: creation of the gastric pouch; task 3: gastrojejunal anastomosis). Comparing the groups, no significant differences were found in task 1. Analyzing the results from the gastric bypass module (bariatric vs. general), in task 2, significant differences (p < 0.05) were found in the median volume of the gastric pouch (21 vs. 48 cm(3)), in the percentage of fundus included in the pouch (8.4 vs. 29.4 %), in the complete dissection at the angle of His (10 vs. 3), and in safety parameters. In task 3, significant differences were found in the size and position of enterotomies. The Lap Mentor may be proposed as a certification tool for bariatric surgeons because it also recognizes their specific skills in the technical details of the procedure that affect long-term results. Furthermore, the possibility of analyzing the performance in detail can help define areas where the surgeon is lacking. These findings indicate a potential role of the Lap Mentor in tailoring the training to maximize improvement.

The need for standard endovascular neurosurgical (ENS) training programs and certification in Korea cannot be overlooked due to the increasing number of ENS specialists and the expanding ENS field. The Society of Korean Endovascular Neurosurgeons (SKEN) Certification Committee has prepared training programs and certification since 2010, and the first certificates were issued in 2013. A task force team (TFT) was organized in August 2010 to develop training programs and certification. TFT members researched programs and systems in other countries to develop a program that best suited Korea. After 2 years, a rough draft of the ENS training and certification regulations were prepared, and the standard training program title was decided. The SKEN Certification Committee made an official announcement about the certification program in March 2013. The final certification regulations comprised three major parts: certified endovascular neurosurgeons (EN), certified ENS institutions, and certified ENS training institutions. Applications have been evaluated and the results were announced in June 2013 as follows: 126 members received EN certification and 55 hospitals became ENS-certified institutions. The SKEN has established standard ENS training programs together with a certification system, and it is expected that they will advance the field of ENS to enhance public health and safety in Korea.

During the past 40 years, health education has taken significant steps toward improving quality assurance in professional preparation through individual certification and program approval and accreditation. Although the profession has begun to embrace individual certification, program accreditation in health education has been neither uniformly available nor universally accepted by institutions of higher education. To further strengthen professional preparation in health education, the Society for Public Health Education (SOPHE) and the American Association for Health Education (AAHE) established the National Task Force on Accreditation in Health Education in 2001. The 3-year Task Force was charged with developing a detailed plan for a coordinated accreditation system for undergraduate and graduate programs in health education. This article summarizes the Task Force's findings and recommendations, which have been approved by the SOPHE and AAHE boards, and, if implemented, promise to lay the foundation for the highest quality professional preparation and practice in health education.

Background The proportion of Japanese workers experiencing intense worry or stress during working life is in excess of 60%, and the incidence of psychiatric disorders and suicide due to psychological burden from work duties is increasing. To confirm whether the stress response measured by the Brief Job Stress Questionnaire (BJSQ) can identify risk for depression, a cohort study was conducted to evaluate whether the stress response measured by BJSQ was associated with the onset of depression. Methods A total of 1,810 participants aged 20–70 years in 2005 completed the stress response of the BJSQ and were followed-up until August, 2007 by examining sick pay records. Depression was defined by a description in sick pay records that included “depression” or “depressive symptoms” as a reason for sick leave according to a physician's medical certificate. The participants were divided into quartiles (Ql, Q2, Q3, and Q4) according to the total stress response score of BJSQ at baseline. Furthermore, the participants were divided into a higher score category (Q4) and a lower score category (Q1–Q3). Risk ratios of the stress response of the BJSQ for onset of depression were calculated using a multivariable Cox proportional hazard model. Results Among 1,810 participants, 14 developed depression during a mean of 1.8 years of follow-up. The risk ratio was 2.96 (95% confidence interval [CI], 1.04–8.42, p for trend = 0.002) when the higher stress response score category of BJSQ was compared with the low stress response score category for sick leave due to depression. After adjusting for gender, age, marital status, and having children, the risk ratios were similar to no adjustment. Conclusions These findings suggest that the stress response measured by the BJSQ can demonstrate risk for the onset of depression. PMID:23424656

Ground-based training for the stimulus rearrangement encountered during spaceflight

1988-01-01

Approximately 65-70% of the crew members now experience motion sickness of some degree during the first 72 h of orbital flight on the Space Shuttle. Lack of congruence among signals from spatial orientation systems leads to sensory conflict, which appears to be the basic cause of space motion sickness. A project to develop training devices and procedures to preadapt astronauts to the stimulus rearrangements of microgravity is currently being pursued. The preflight adaptation trainers (PATs) are intended to: demonstrate sensory phenomena likely to be experienced in flight, allow astronauts to train preflight in an altered sensory environment, alter sensory-motor reflexes, and alleviate or shorten the duration of space motion sickness. Four part-task PATs are anticipated. The trainers are designed to evoke two adaptation processes, sensory compensation and sensory reinterpretation, which are necessary to maintain spatial orientation in a weightless environment. Recent investigations using one of the trainers indicate that self-motion perception of linear translation is enhanced when body tilt is combined with visual surround translation, and that a 270 degrees phase angle relationship between tilt and surround motion produces maximum translation perception.

Virtual reality body motion induced navigational controllers and their effects on simulator sickness and pathfinding.

PubMed

Aldaba, Cassandra N; White, Paul J; Byagowi, Ahmad; Moussavi, Zahra

2017-07-01

Virtual reality (VR) navigation is usually constrained by plausible simulator sickness (SS) and intuitive user interaction. The paper reports on the use of four different degrees of body motion induced navigational VR controllers, a TiltChair, omni-directional treadmill, a manual wheelchair joystick (VRNChair), and a joystick in relation to a participant's SS occurrence and a controller's intuitive utilization. Twenty young adult participants utilized all controllers to navigate through the same VR task environment in separate sessions. Throughout the sessions, SS occurrence was measured from a severity score by a standard SS questionnaire and from body sway by a center of pressure path length with eyes opened and closed. SS occurrence did not significantly differ among the controllers. However, time spent in VR significantly contributed to SS occurrence; hence, a few breaks to minimize SS should be interjected throughout a VR task. For all task trials, we recorded the participant's travel trajectories to investigate each controller's intuitive utilization from a computed traversed distance. Shorter traversed distances indicated that participants intuitively utilized the TiltChair with a slower speed; while longer traversed distances indicated participants struggled to utilize the omni-directional treadmill with a unnaturalistic stimulation of gait. Therefore, VR navigation should use technologies best suited for the intended age group that minimizes SS, and produces intuitive interactions for the participants.

The brain networks supporting nausea not yet understood. We previously found that while visual stimulation activated primary (V1) and extrastriate visual cortices (MT+/V5, coding for visual motion), increasing nausea was associated with increasing sustained activation in several brain areas, with significant co-activation for anterior insula (aIns) and mid-cingulate (MCC) cortices. Here, we hypothesized that motion sickness also alters functional connectivity between visual motion and previously identified nausea-processing brain regions. Subjects prone to motion sickness and controls completed a motion sickness provocation task during fMRI/ECG acquisition. We studied changes in connectivity between visual processing areas activated by the stimulus (MT+/V5, V1), right aIns and MCC when comparing rest (BASELINE) to peak nausea state (NAUSEA). Compared to BASELINE, NAUSEA reduced connectivity between right and left V1 and increased connectivity between right MT+/V5 and aIns and between left MT+/V5 and MCC. Additionally, the change in MT+/V5 to insula connectivity was significantly associated with a change in sympathovagal balance, assessed by heart rate variability analysis. No state-related connectivity changes were noted for the control group. Increased connectivity between a visual motion processing region and nausea/salience brain regions may reflect increased transfer of visual/vestibular mismatch information to brain regions supporting nausea perception and autonomic processing. We conclude that vection-induced nausea increases connectivity between nausea-processing regions and those activated by the nauseogenic stimulus. This enhanced low-frequency coupling may support continual, slowly evolving nausea perception and shifts toward sympathetic dominance. Disengaging this coupling may be a target for biobehavioral interventions aimed at reducing motion sickness severity. Copyright © 2016 Elsevier B.V. All rights reserved.

Virtual reality (VR) opens up a vast number of possibilities in many domains of therapy. The primary objective of the present study was to evaluate the acceptability for elderly subjects of a VR experience using the image-based rendering virtual environment (IBVE) approach and secondly to test the hypothesis that visual cues using VR may enhance the generation of autobiographical memories. Eighteen healthy volunteers (mean age 68.2 years) presenting memory complaints with a Mini-Mental State Examination score higher than 27 and no history of neuropsychiatric disease were included. Participants were asked to perform an autobiographical fluency task in four conditions. The first condition was a baseline grey screen, the second was a photograph of a well-known location in the participant's home city (FamPhoto), and the last two conditions displayed VR, ie, a familiar image-based virtual environment (FamIBVE) consisting of an image-based representation of a known landmark square in the center of the city of experimentation (Nice) and an unknown image-based virtual environment (UnknoIBVE), which was captured in a public housing neighborhood containing unrecognizable building fronts. After each of the four experimental conditions, participants filled in self-report questionnaires to assess the task acceptability (levels of emotion, motivation, security, fatigue, and familiarity). CyberSickness and Presence questionnaires were also assessed after the two VR conditions. Autobiographical memory was assessed using a verbal fluency task and quality of the recollection was assessed using the "remember/know" procedure. All subjects completed the experiment. Sense of security and fatigue were not significantly different between the conditions with and without VR. The FamPhoto condition yielded a higher emotion score than the other conditions (P<0.05). The CyberSickness questionnaire showed that participants did not experience sickness during the experiment across the VR conditions. VR stimulates autobiographical memory, as demonstrated by the increased total number of responses on the autobiographical fluency task and the increased number of conscious recollections of memories for familiar versus unknown scenes (P<0.01). The study indicates that VR using the FamIBVE system is well tolerated by the elderly. VR can also stimulate recollections of autobiographical memory and convey familiarity of a given scene, which is an essential requirement for use of VR during reminiscence therapy.

Slaughtering sick poultry is a risk factor for human infection with highly pathogenic avian influenza and is a common practice in Bangladesh. This paper describes human exposures to poultry during slaughtering process and the customs and rituals influencing these practices in two Bangladeshi rural communities. In 2009, we conducted 30 observations to observe slaughtering practices and 110 in-depth and short interviews and 36 group discussions to explore reasons behind those practices. The villagers reported slaughtering 103 poultry, including 20 sick poultry during 2 months. During different stages of slaughtering, humans, the environment, healthy poultry, and other animals were exposed to poultry blood and body parts. Women performed most of the slaughtering tasks, including evisceration. Defeathering required the most time and involved several persons. During festivals, ceremonies, and rituals, many people gathered and participated in the slaughtering of poultry. Exposure to poultry slaughtering created numerous opportunities for potential avian influenza transmission. Strategies that can be further tested to determine if they reduce the risk of transmission include skinning the carcasses of sick poultry, using hot water for defeathering and cleaning, using a bucket to contain slaughtering blood and carcass, burying the offal and encouraging handwashing.

How do general practitioners contribute to preventing long-term work disability of their patients suffering from depressive disorders? A qualitative study.

Depression is a major cause of work absenteeism that general practitioners (GPs) face directly since they are responsible for sickness certification and for supervising the return to work (RTW). These activities give GPs a key role in preventing long-term work disability, yet their practices in this regard remain poorly documented. The objectives of this study were therefore to describe GPs' practices with people experiencing work disability due to depressive disorders and explore how GPs' work context may impact on their practices. We conducted semi-structured individual interviews with 13 GPs and six mental healthcare professionals in two sub-regions of Quebec. The sub-regions differed in terms of availability of specialized resources offering public mental health services. Data were anonymized and transcribed verbatim. Thematic analysis was performed to identify patterns in the GPs' practices and highlight impacting factors in their work context. Our results identified a set of practices common to all the GPs and other practices that differentiated them. Two profiles were defined on the basis of the various practices documented. The first is characterized by the integration of the RTW goal into the treatment goal right from sickness certification and by interventions that include the workplace, albeit indirectly. The second is characterized by a lack of early RTW-oriented action and by interventions that include little workplace involvement. Regardless of the practice profile, actions intended to improve collaboration with key stakeholders remain the exception. However, two characteristics of the work context appear to have an impact: the availability of a dedicated mental health nurse and the regular provision of clinical information by psychotherapists. These conditions are rarely present but tend to make a significant difference for the GPs. Our results highlight the significant role of GPs in the prevention of long-term work disability and their need for support through the organization of mental health services at the primary care level.

Aims: To examine the association between components of organisational justice (that is, justice of decision making procedures and interpersonal treatment) and health of employees. Methods: The Poisson regression analyses of recorded all-cause sickness absences with medical certificate and the logistic regression analyses of minor psychiatric morbidity, as assessed by the General Health Questionnaire, and poor self rated health status were based on a cohort of 416 male and 3357 female employees working during 1998–2000 in 10 hospitals in Finland. Results: Low versus high justice of decision making procedures was associated with a 41% higher risk of sickness absence in men (rate ratio (RR) 1.4, 95% confidence interval (CI) 1.1 to 1.8), and a 12% higher risk in women (RR 1.1, 95% CI 1.0 to 1.2) after adjustment for baseline characteristics. The corresponding odds ratios (OR) for minor psychiatric morbidity were 1.6 (95% CI 1.0 to 2.6) in men and 1.4 (95% CI 1.2 to 1.7) in women, and for self rated health 1.4 in both sexes. In interpersonal treatment, low justice increased the risk of sickness absence (RR 1.3 (95% CI 1.0 to 1.6) and RR 1.2 (95% CI 1.2 to 1.3) in men and women respectively), and minor psychiatric morbidity (OR 1.2 in both sexes). These figures largely persisted after control for other risk factors (for example, job control, workload, social support, and hostility) and they were replicated in initially healthy subcohorts. No evidence was found to support the hypothesis that organisational justice would represent a consequence of health (reversed causality). Conclusions: This is the first longitudinal study to show that the extent to which people are treated with justice in workplaces independently predicts their health. PMID:12499453

The influence of ship motion of manual control skills

NASA Technical Reports Server (NTRS)

Mcleod, P.; Poulton, C.; Duross, H.; Lewis, W.

1981-01-01

The effects of ship motion on a range of typical manual control skills were examined on the Warren Spring ship motion simulator driven in heave, pitch, and roll by signals taken from the frigate HMS Avenger at 13 m/s (25 knots) into a force 4 wind. The motion produced a vertical r.m.s. acceleration of 0.024g, mostly between 0.1 and 0.3 Hz, with comparatively little pitch or roll. A task involving unsupported arm movements was seriously affected by the motion; a pursuit tracking task showed a reliable decrement although it was still performed reasonably well (pressure and free moving tracking controls were affected equally by the motion); a digit keying task requiring ballistic hand movements was unaffected. There was no evidence that these effects were caused by sea sickness. The differing response to motion of the different tasks, from virtual destruction to no effect, suggests that a major benefit could come from an attempt to design the man/control interface onboard ship around motion resistant tasks.

Involvement and structure: A qualitative study of organizational change and sickness absence among women in the public sector in Sweden

PubMed Central

2011-01-01

Background Organizational changes in modern corporate life have become increasingly common and there are indications that they often fail to achieve their ends. An earlier study of 24,036 employees showed that those who had repeatedly been exposed to large increases in staffing during 1991-1996 had an excess risk of both long-term sickness absence and hospital admission during 1997-1999, while moderate expansion appeared to be protective. The former was most salient among female public sector employees. We used qualitative interviews to explore work environment factors underlying the impact of organizational changes (moderate and large expansions in staffing) on sickness absence from an employee perspective. Method We interviewed 21 strategically selected women from the earlier study using semi-structured telephone interviews focusing on working conditions during the organizational changes. We identified 22 themes which could explain the association between organizational changes and sickness absence. We then used Qualitative Comparative Analysis (QCA) to reduce the number of themes and discover patterns of possible causation. Results The themes that most readily explained the outcomes were Well Planned Process of Change (a clear structure for involvement of the employees in the changes), Agent of Change (an active role in the implementation of the changes), Unregulated Work (a lack of clear limits and guidelines regarding work tasks from the management and among the employees), and Humiliating Position (feelings of low status or of not being wanted at the workplace), which had been salient throughout the analytic process, in combination with Multiple Contexts (working in several teams in parallel) and Already Ill (having already had a debilitating illness at the beginning of 1991), which may indicate degree of individual exposure and vulnerability. Well Planned Process of Change, Agent of Change and Multiple Contexts are themes that were associated with low sickness absence. Unregulated Work, Humiliating Position and Already Ill were associated with high sickness absence. Conclusions These findings suggest that promising areas for future research and improvement in change management could be the structured involvement of the employees in the planning of organizational changes, and the development of methods to avoid highly unregulated working conditions.

Respiratory diseases are a cause of long-term sickness absence, and even of partial or complete inability to work. This paper presents the first in Poland description of principles of good practice in occupational health service provided for people with respiratory diseases. The issues concerning the certification of the ability to work in this group of patients are discussed. The key-principles of preventive care of workers with obstructive and interstitial lung diseases with particular attention paid to the control of major risk factors are also presented. The importance of possible contraindications for job performance by workers affected by these diseases, as well as the responsibilities of occupational health physicians were highlighted. M

This paper depicts the solution proposed by INFN to allow users, not owning a personal digital certificate and therefore not belonging to any specific Virtual Organization (VO), to access Grid infrastructures via the GENIUS Grid portal enabled with robot certificates. Robot certificates, also known as portal certificates, are associated with a specific application that the user wants to share with the whole Grid community and have recently been introduced by the EUGridPMA (European Policy Management Authority for Grid Authentication) to perform automated tasks on Grids on behalf of users. They are proven to be extremely useful to automate grid service monitoring, data processing production, distributed data collection systems, etc. In this paper, robot certificates have been used to allow bioinformaticians involved in the Italian LIBI project to perform large scale phylogenetic analyses. The distributed environment set up in this work strongly simplify the grid access of occasional users and represents a valuable step forward to wide the communities of users.

2004-10-21

Musculoskeletal disorders are important causes of sick leave and disability among Norwegian offshore petroleum workers. More knowledge and interventions are needed in order to prevent this. In this review we consider prevalence and risk factors among offshore petroleum workers and point to the need for more research. Literature searches on ISI Web of Science and PubMed were supplemented by reports from Norwegian offshore industry companies and the Norwegian Petroleum Directorate. Few studies were found on musculoskeletal disorders among offshore petroleum workers. The disorders are widespread, particularly among catering, construction and drilling personnel. It is not clear whether the prevalence is different from that among onshore workers. Risk factors are physical stressors and fast pace of work. Among catering personnel, these disorders are important causes of loss of the required health certificate but we could not identify any review of causes in the offshore industry generally. More scientific studies are needed on musculoskeletal disorders as comparisons of prevalence and risk factors for offshore and onshore workers may point to more effective interventions. Better knowledge of the causes of loss of the health certificate may contribute to preventing early retirement. Interventions to prevent these disorders should be evaluated by controlled intervention studies.

Tolerance to extended galvanic vestibular stimulation: optimal exposure for astronaut training.

PubMed

Dilda, Valentina; MacDougall, Hamish G; Moore, Steven T

2011-08-01

We have developed an analogue of postflight sensorimotor dysfunction in astronauts using pseudorandom galvanic vestibular stimulation (GVS). To date there has been no study of the effects of extended GVS on human subjects and our aim was to determine optimal exposure for astronaut training based on tolerance to intermittent and continuous galvanic stimulation. There were 60 subjects who were exposed to a total of 10.5 min of intermittent GVS at a peak current of 3.5 mA or 5 mA. A subset of 24 subjects who tolerated the intermittent stimulus were subsequently exposed to 20-min continuous stimulation at 3.5 mA or 5 mA. During intermittent GVS the large majority of subjects (78.3%) reported no or at most mild motion sickness symptoms, 13.3% reported moderate symptoms, and 8.3% experienced severe nausea and requested termination of the stimulus. During 20-min continuous exposure, 83.3% of subjects reported no or at most mild motion sickness symptoms and 16.7% (all in the 5-mA group) experienced severe nausea. Based on these results, we propose two basic modes of GVS application to minimize the incidence of motion sickness: intermittent high (5 mA) amplitude, suited to simulation of intensive operator tasks requiring a high-fidelity analogue of postflight sensorimotor dysfunction such as landing or docking maneuvers; and continuous low (3.5 mA) amplitude stimulation, for longer simulation scenarios such as extra vehicular activity. Our results suggest that neither mode of stimulation would induce motion sickness in the large majority of subjects for up to 20 min exposure.

Analysis of Counterfactual Quantum Certificate Authorization

2016-12-01

A counterfactual quantum certificate authorization protocol was proposed recently (Shenoy et al., Phys. Rev. A 89, 052307 (20)), in which a trusted third party, Alice, authenticates an entity Bob (e.g., a bank) that a client Charlie wishes to securely transact with. However, this protocol requires a classical authenticated channel between Bob and Charlie to prevent possible attacks from the third party Alice, which is in conflict with the task of certificate authorization in the sense that Bob and Charlie can establish an unconditionally-secure key by a quantum key distribution protocol if there is a classical authenticated channel between them and hence securely transact with each other even without the assistance of the third party Alice.

Age differences in the associations between sick leave and aspects of health, psychosocial workload and family life: a cross-sectional study

Objectives To investigate differences in associations between sick leave and aspects of health, psychosocial workload, family life and work–family interference between four age groups (<36, 36–45, 46–55 and 55+ years). Design A cross-sectional study; a questionnaire was sent to the home addresses of all employees of a university. Setting A Dutch university. Participants 1843 employees returned the questionnaire (net response: 49.1%). The age distribution was as follows: <36: 32%; 36–45: 26%; 46–55: 27% and 55+: 12%. Primary outcomes Frequent sick leave (FSL, ≥3 times in the past 12 months) and prolonged sick leave (PSL, >2 weeks in total in the past 12 months). Differences between the age groups in independent variables and outcomes were investigated. Logistic regression analysis was used to calculate associations between various variables and the sick leave outcomes. Interaction terms were included to detect differences between the age groups. Results Age differences were found for many work- and family-related characteristics but not in the mean scores for health-related aspects. Presence of chronic disease was reported more frequently with increasing age. The 55+ age group had almost two times less chance of FSL, but 1.6 times more chance of PSL than the <36 age group. Age moderates the associations between career opportunities, partner's contribution in domestic tasks and sex, and FSL. Job security and pay, support from supervisor, challenging work and being breadwinner have different associations with PSL. However, life events in private lives and perceived health complaints are important in all age groups. FSL and PSL have some determinants in common, but there are differences between the outcomes as well. Conclusions Age should be treated as a variable of interest instead of a control variable. Employers and occupational physicians need to be aware that each phase in life has specific difficulties that can lead to FSL and PSL. PMID:22855622

Edelman, David A; Mattos, Mark A; Bouwman, David L

2011-09-01

Fundamentals of Laparoscopic Surgery (FLS) certification is a high stakes examination. The best training methods to enable successful certification are undetermined. We hypothesized that first year surgical residents (R01s) who had been pretrained as medical students would perform better during skills training than previously un-trained R01s. This is an IRB-approved, retrospective review of FLS training data generated from a single surgical skills laboratory from July 2007 through June 2010. During the study period, there were 24 R01s with no previous FLS exposure (NOVICE group) and seven R01s who had undergone FLS task training while medical students (MS4 group). All R01s practiced the FLS skill tasks weekly for portions of the training sessions with informal feedback and teaching. Performance goals were proposed for each task based on local and national proficiency figures. The performance outcome measure was task completion time (TCT). Pretraining performance was designated iTCT and post-training fTCT. The MS4 group began with iTCTs for all four tasks that were significantly lower than the NOVICE iTCTs. At completion of the 16-wk training period, the MS4 group continued to demonstrate mean fTCTs that were lower for all four FLS skill tasks but only significantly for PEG, CIRCLE, and INTRA skill tasks. Both NOVICE and MS4 groups showed significant improvement for all four skill tasks (P < 0.05). In the current milieu of work-hour limitations, the integration of FLS skill training into medical school curriculum provided a durable advantage to the pretrained R01s, which was associated with higher levels of final performance.

Work-related respiratory disease in employees leaving an electronics factory.

Perks, W H; Burge, P S; Rehahn, M; Green, M

Examination of the records of employees leaving an electronics factory over three-and-a-half years showed that a significantly greater proportion left the shop floor (where soldering took place) because of ill health than left the stores and office areas. This difference was largely due to work-related respiratory disease in those whose job was soldering. Shop floor workers leaving for health reasons also had increased sickness certification due to respiratory illness compared to stores and office workers. These findings suggest that work-related respiratory illness is a significant cause of morbidity and loss of employment in solderers working at the factory and that this has been a longstanding problem with its onset before the first recorded cases of occupational asthma caused by solder flux containing colophony.

When rational men fall sick: an inquiry into some assumptions made by medical anthropologists.

PubMed

Young, A

1981-12-01

Medical anthropologist spend most of their time eliciting and interpreting people's statements about sickness and health. For this task, they make certain assumptions about the importance of language and reason. In this paper I argue that their assumptions are tailored to fit an hypothetical Rational Man rather than real people. The concept of 'explanatory models of sickness' is used to illustrate this point. My critique begins by drawing attention to two non-cognitive determinants of people's statements: their degree of emotional arousal and their capacities for discoursing on medical subjects. These determinants are briefly discussed and then set aside, to make room for the paper's argument proper. This starts with the observation that medical anthropologists tend to overlook the fact that they have established a cognitive no man's land stretching between their informants' statements and the cognitive structures which are supposed to generate these statements. I survey this void, using a five-fold model of medical knowledge. People use one kind of knowledge to organize their medical experiences and perceptions. In Rational Man writing, this form of knowledge is considered equivalent to cognitive structures (e.g., causal models, classificatory schemes), but I argue that is also includes knowledge of prototypical sickness events and knowledge that is embedded in actions, social relations, and material equipment. The theoretical implications of the five-fold model are outlined. This is followed by an analysis of the reasoning processes in which people use medical knowledge to produce the statements whose meaning we wish to learn. I demonstrate the importance of being able to distinguish operational and monothetic forms of reasoning from pre-operational and polythetic ones. Rational Man writers are described as ignoring the latter pair. The concept of 'prototypes' is reintroduced to illustrate these points.

Inflammation-induced sickness is associated with a large set of behavioral alterations; however, its motivational aspects remain poorly explored in humans. The present study assessed the effect of lipopolysaccharide (LPS) administration at a dose of 2 ng/kg of body weight on motivation in 21 healthy human subjects in a double-blinded, placebo (saline)-controlled, cross-over design. Incentive motivation and reward sensitivity were measured using the Effort Expenditure for Rewards Task (EEfRT), in which motivation for high-effort/high-reward trials vs low-effort/low-reward trials are manipulated by variations in reward magnitude and probability to win. Because of the strong interactions between sleepiness and motivation, the role of sleepiness was also determined. As expected, the probability to win predicted the choice to engage in high-effort/high-reward trials; however, this occurred at a greater extent after LPS than after saline administration. This effect was related to the level of sleepiness. Sleepiness increased motivation to choose the high-effort/high-reward mode of response, but only when the probability to win was the highest. LPS had no effect on reward sensitivity either directly or via sleepiness. These results indicate that systemic inflammation induced by LPS administration causes motivational changes in young healthy subjects, which are associated with sleepiness. Thus, despite its association with energy-saving behaviors, sickness allows increased incentive motivation when the effort is deemed worthwhile.

We present a multipartite protocol in a counterfactual paradigm. In counterfactual quantum cryptography, secure information is transmitted between two spatially separated parties even when there is no physical travel of particles transferring the information between them. We propose here a tripartite counterfactual quantum protocol for the task of certificate authorization. Here a trusted third party, Alice, authenticates an entity Bob (e.g., a bank) that a client Charlie wishes to securely transact with. The protocol is counterfactual with respect to either Bob or Charlie. We prove its security against a general incoherent attack, where Eve attacks single particles.

Immigrants’ use of emergency primary health care in Norway: a registry-based observational study

PubMed Central

2012-01-01

Background Emigrants are often a selected sample and in good health, but migration can have deleterious effects on health. Many immigrant groups report poor health and increased use of health services, and it is often claimed that they tend to use emergency primary health care (EPHC) services for non-urgent purposes. The aim of the present study was to analyse immigrants’ use of EPHC, and to analyse variations according to country of origin, reason for immigration, and length of stay in Norway. Methods We conducted a registry based study of all immigrants to Norway, and a subsample of immigrants from Poland, Germany, Iraq and Somalia, and compared them with native Norwegians. The material comprised all electronic compensation claims for EPHC in Norway during 2008. We calculated total contact rates, contact rates for selected diagnostic groups and for services given during consultations. Adjustments for a series of socio-demographic and socio-economic variables were done by multiple logistic regression analyses. Results Immigrants as a whole had a lower contact rate than native Norwegians (23.7% versus 27.4%). Total contact rates for Polish and German immigrants (mostly work immigrants) were 11.9% and 7.0%, but for Somalis and Iraqis (mostly asylum seekers) 31.8% and 33.6%. Half of all contacts for Somalis and Iraqis were for non-specific pain, and they had relatively more of their contacts during night than other groups. Immigrants’ rates of psychiatric diagnoses were low, but increased with length of stay in Norway. Work immigrants suffered less from respiratory and gastrointestinal infections, but had more injuries and higher need for sickness certification. All immigrant groups, except Germans, were more often given a sickness certificate than native Norwegians. Use of interpreter was reduced with increasing length of stay. All immigrant groups had an increased need for long consultations, while laboratory tests were most often used for Somalis and Iraqis. Conclusions Immigrants use EPHC services less than native Norwegians, but there are large variations among immigrant groups. Work immigrants from Germany and Poland use EPHC considerably less, while asylum seekers from Somalia and Iraq use these services more than native Norwegians. PMID:22958343

Effect of stratified care for low back pain in family practice (IMPaCT Back): a prospective population-based sequential comparison.

2014-01-01

We aimed to determine the effects of implementing risk-stratified care for low back pain in family practice on physician's clinical behavior, patient outcomes, and costs. The IMPaCT Back Study (IMplementation to improve Patient Care through Targeted treatment) prospectively compared separate patient cohorts in a preintervention phase (6 months of usual care) and a postintervention phase (12 months of stratified care) in family practice, involving 64 family physicians and linked physical therapy services. A total of 1,647 adults with low back pain were invited to participate. Stratified care entailed use of a risk stratification tool to classify patients into groups at low, medium, or high risk for persistent disability and provision of risk-matched treatment. The primary outcome was 6-month change in disability as assessed with the Roland-Morris Disability Questionnaire. Process outcomes captured physician behavior change in risk-appropriate referral to physical therapy, diagnostic tests, medication prescriptions, and sickness certifications. A cost-utility analysis estimated incremental quality-adjusted life-years and back-related health care costs. Analysis was by intention to treat. The 922 patients studied (368 in the preintervention phase and 554 in the postintervention phase) had comparable baseline characteristics. At 6 months follow-up, stratified care had a small but significant benefit relative to usual care as seen from a mean difference in Roland-Morris Disability Questionnaire scores of 0.7 (95% CI, 0.1-1.4), with a large, clinically important difference in the high risk group of 2.3 (95% CI, 0.8-3.9). Mean time off work was 50% shorter (4 vs 8 days, P = .03) and the proportion of patients given sickness certifications was 30% lower (9% vs 15%, P = .03) in the postintervention cohort. Health care cost savings were also observed. Stratified care for back pain implemented in family practice leads to significant improvements in patient disability outcomes and a halving in time off work, without increasing health care costs. Wider implementation is recommended.

Stereoscopic 3D entertainment and its effect on viewing comfort: comparison of children and adults.

PubMed

Pölönen, Monika; Järvenpää, Toni; Bilcu, Beatrice

2013-01-01

Children's and adults' viewing comfort during stereoscopic three-dimensional film viewing and computer game playing was studied. Certain mild changes in visual function, heterophoria and near point of accommodation values, as well as eyestrain and visually induced motion sickness levels were found when single setups were compared. The viewing system had an influence on viewing comfort, in particular for eyestrain levels, but no clear difference between two- and three-dimensional systems was found. Additionally, certain mild changes in visual functions and visually induced motion sickness levels between adults and children were found. In general, all of the system-task combinations caused mild eyestrain and possible changes in visual functions, but these changes in magnitude were small. According to subjective opinions that further support these measurements, using a stereoscopic three-dimensional system for up to 2 h was acceptable for most of the users regardless of their age.

Thirty years of public health research have demonstrated that improved indoor environmental quality is associated with better health outcomes. Recent research has demonstrated an impact of the indoor environment on cognitive function. We recruited 109 participants from 10 high-performing buildings (i.e. buildings surpassing the ASHRAE Standard 62.1-2010 ventilation requirement and with low total volatile organic compound concentrations) in five U.S. cities. In each city, buildings were matched by week of assessment, tenant, type of worker and work functions. A key distinction between the matched buildings was whether they had achieved green certification. Workers were administered a cognitive function test of higher order decision-making performance twice during the same week while indoor environmental quality parameters were monitored. Workers in green certified buildings scored 26.4% (95% CI: [12.8%, 39.7%]) higher on cognitive function tests, controlling for annual earnings, job category and level of schooling, and had 30% fewer sick building symptoms than those in non-certified buildings. These outcomes may be partially explained by IEQ factors, including thermal conditions and lighting, but the findings suggest that the benefits of green certification standards go beyond measureable IEQ factors. We describe a holistic "buildingomics" approach for examining the complexity of factors in a building that influence human health.

Validation of sick leave measures: self-reported sick leave and sickness benefit data from a Danish national register compared to multiple workplace-registered sick leave spells in a Danish municipality

PubMed Central

2012-01-01

Background Previous validation studies of sick leave measures have focused on self-reports. Register-based sick leave data are considered to be valid; however methodological problems may be associated with such data. A Danish national register on sickness benefit (DREAM) has been widely used in sick leave research. On the basis of sick leave records from 3,554 and 2,311 eldercare workers in 14 different workplaces, the aim of this study was to: 1) validate registered sickness benefit data from DREAM against workplace-registered sick leave spells of at least 15 days; 2) validate self-reported sick leave days during one year against workplace-registered sick leave. Methods Agreement between workplace-registered sick leave and DREAM-registered sickness benefit was reported as sensitivities, specificities and positive predictive values. A receiver-operating characteristic curve and a Bland-Altman plot were used to study the concordance with sick leave duration of the first spell. By means of an analysis of agreement between self-reported and workplace-registered sick leave sensitivity and specificity was calculated. Ninety-five percent confidence intervals (95% CI) were used. Results The probability that registered DREAM data on sickness benefit agrees with workplace-registered sick leave of at least 15 days was 96.7% (95% CI: 95.6-97.6). Specificity was close to 100% (95% CI: 98.3-100). The registered DREAM data on sickness benefit overestimated the duration of sick leave spells by an average of 1.4 (SD: 3.9) weeks. Separate analysis on pregnancy-related sick leave revealed a maximum sensitivity of 20% (95% CI: 4.3-48.1). The sensitivity of self-reporting at least one or at least 56 sick leave day/s was 94.5 (95% CI: 93.4 – 95.5) % and 58.5 (95% CI: 51.1 – 65.6) % respectively. The corresponding specificities were 85.3 (95% CI: 81.4 – 88.6) % and 98.9 (95% CI: 98.3 – 99.3) %. Conclusions The DREAM register offered valid measures of sick leave spells of at least 15 days among eldercare employees. Pregnancy-related sick leave should be excluded in studies planning to use DREAM data on sickness benefit. Self-reported sick leave became more imprecise when number of absence days increased, but the sensitivity and specificity were acceptable for lengths not exceeding one week. PMID:22894644

A Countermeasure for Space Motion Sickness

2006-01-01

Overall, the results obtained in both the U.S. and the Russian space programs indicate that most space crews will experience some symptoms of motion sickness (MS) causing significant impact on the operational objectives that must be accomplished to assure mission success. At this time the primary countermeasure for MS requires the administration of Promethazine. Promethazine is not a benign drug, and is most frequently administered just prior to the sleep cycle to prevent its side effects from further compromising mission objectives. Clearly other countermeasures for SMS must be developed. Currently the primary focus is on two different technologies: (1) developing new and different pharmacological compounds with less significant side effects, (2) preflight training. The primary problem with all of these methods for controlling MS is time. New drugs that may be beneficial are years from testing and development, and preflight training requires a significant investment of crew time during an already intensive pre-launch schedule. Granted, motion sickness symptoms can be minimized with either of the two methods detailed above, however, it may be possible to develop a countermeasure that does not require either extensive adaptation time or exposure to motion sickness. Approximately 25 years ago Professor Geoffrey Melvill Jones presented his work on adaptation of the vestibuloocular reflex (VOR) using optically reversed vision (left-right prisms) during head rotations in the horizontal plane. It was of no surprise that most subjects experienced motion sickness while wearing the optically reversing prisms. However, a serendipitous finding emerged during this research showing that the same subjects did not experience motion sickness symptoms when wearing the reversing prisms under stroboscopic illumination. The mechanism, by which this side-effect was believed to have occurred, is not clearly understood. However, the fact that no motion sickness was ever noted, suggests the possibility of producing functionally useful adaptation during space flight without the penalty of disabling motion sickness by controlling the rate of the adaptive process by means of an appropriate stroboscopically presented environment. After several recent meetings with Professor Melvill Jones, we were encouraged to repeat the motion sickness portions of his and Mandl's 1981 stroboscopic experiment. In conducting this experiment we used a randomized cross-over design where subjects were randomly assigned to either a stroboscopic flash or no strobe for their first exposure in the experimental design. Twenty subjects (19 subjects completed the study) read a short passage from Treasure Island mounted on the wall approximately 1 m from their eyes while wearing left-right reversing prisms. The strobe on time of 3 microseconds and flash frequency of 4 Hz was set to equal that used in the original study. Motion sickness was scored using a modified Miller and Graybiel scale that we constructed to include symptoms that may be elicited under conditions where reversing prisms are worn. On this scale a score of 5 represented Malaise IIa (mild motion sickness) and a score of 8 or above is approaching frank sickness. Symptoms were tracked and recorded every 5 min during the task. Testing was limited to 30 min unless the subject had reached the MIIa score, at which time the test was terminated. Performance under stroboscopic illumination was significantly better than when the subjects read under normal room illumination while wearing the left-right reversing prisms. Based on these results we developed a goggle system using LCD material that can be strobed. To evaluate the effectiveness of stroboscopic goggles we tested an additional 9 subjects in addition to retesting 10 used in the stroboscopic pilot study described above. These 19 subjects wore a pair of strobing LCD goggles that could be cycled at 4 Hz. These subjects wore the goggles while also wearing left-right reversg prisms. Results while wearing the goggles showed that none of the 19 subjects scored at the MIIa level on the motion sickness rating scale. When the goggles did not flash (no strobe), 11 of the 19 developed symptoms above the MIIa criteria. As a countermeasure the goggles seem to be effective, even with an on time of 10 msec (time the goggles are clear). We have also collected anecdotal data, from our personnel in the Neuroscience Laboratory at the Johnson Space Center, suggesting that the goggles may effective in preventing carsickness.

Associations between partial sickness benefit and disability pensions: initial findings of a Finnish nationwide register study.

Timely return to work after longterm sickness absence and the increased use of flexible work arrangements together with partial health-related benefits are tools intended to increase participation in work life. Although partial sickness benefit and partial disability pension are used in many countries, prospective studies on their use are largely lacking. Partial sickness benefit was introduced in Finland in 2007. This register study aimed to investigate the use of health-related benefits by subjects with prolonged sickness absence, initially on either partial or full sick leave. Representative population data (13 375 men and 16 052 women either on partial or full sick leave in 2007) were drawn from national registers and followed over an average of 18 months. The registers provided information on the study outcomes: diagnoses and days of payment for compensated sick leaves, and the occurrence of disability pension. Survival analysis and multinomial regression were carried out using sociodemographic variables and prior sickness absence as covariates. Approximately 60% of subjects on partial sick leave and 30% of those on full sick leave had at least one recurrent sick leave over the follow up. A larger proportion of those on partial sick leave (16%) compared to those on full sick leave (1%) had their first recurrent sick leave during the first month of follow up. The adjusted risks of the first recurrent sick leave were 1.8 and 1.7 for men and women, respectively, when subjects on partial sick leave were compared with those on full sick leave. There was no increased risk when those with their first recurrent sick leave in the first month were excluded from the analyses. The risks of a full disability pension were smaller and risks of a partial disability pension approximately two-fold among men and women initially on partial sick leave, compared to subjects on full sick leave. This is the first follow up study of the newly adopted partial sickness benefit in Finland. The results show that compared to full sick leave, partial sick leave - when not followed by lasting return to work - is more typically followed by partial disability pension and less frequently by full disability pension. It is anticipated that the use of partial benefits in connection with part-time participation in work life will have favourable effects on future disability pension rates in Finland.

Part-time sick leave as a treatment method for individuals with musculoskeletal disorders.

PubMed

Andrén, Daniela; Svensson, Mikael

2012-09-01

There is increasing evidence that staying active is an important part of a recovery process for individuals on sick leave due to musculoskeletal disorders (MSDs). It has been suggested that using part-time sick-leave rather than full-time sick leave will enhance the possibility of full recovery to the workforce, and several countries actively favor this policy. The aim of this paper is to examine if it is beneficial for individuals on sick leave due to MSDs to be on part-time sick leave compared to full-time sick leave. A sample of 1,170 employees from the RFV-LS (register) database of the Social Insurance Agency of Sweden is used. The effect of being on part-time sick leave compared to full-time sick leave is estimated for the probability of returning to work with full recovery of lost work capacity. A two-stage recursive bivariate probit model is used to deal with the endogeneity problem. The results indicate that employees assigned to part-time sick leave do recover to full work capacity with a higher probability than those assigned to full-time sick leave. The average treatment effect of part-time sick leave is 25 percentage points. Considering that part-time sick leave may also be less expensive than assigning individuals to full-time sick leave, this would imply efficiency improvements from assigning individuals, when possible, to part-time sick leave.

Accounting for charity care on a systemwide basis.

Peck, T

1988-06-01

The Daughters of Charity National Health System (DCNHS), St. Louis, has developed a systemwide model which formally sets a policy statement, goals, and procedures that enable the 42 DCNHS health-care ministries to effectively serve the poor in their communities on a daily basis, while addressing the long-term challenges of providing charity care for the sick poor. One of the first steps was forming a task force known as the Working Group on Care of the Poor. Its goal was to set the stage for the expansion and accountability of charity care at every level within the new national system. The group outlined these objectives: To identify and recommend several advocacy models. To recommend test models of healthcare delivery for the poor. To recommend strategies for involving the private sector. To develop a method of documenting charity care. To recommend linkage models to jointly provide charity care with related organizations. To gain a firm knowledge of charity care actually provided by the Daughters of Charity After hours of discussions and research, the task force developed a cohesive, workable set of goals and policies that today is helping individual health-care ministries nationwide meet local needs for care of the sick poor. By identifying specific programs and determining how to report charity care in terms of money and services, individual health-care institutions gain insights into their annual operational planning and reporting for the present and the future. This approach ensures that charity care remains in the forefront at every level of planning.

Positive welfare state dynamics? Sickness benefits and sickness absence in Europe 1997-2011.

PubMed

Sjöberg, Ola

2017-03-01

Sickness absence is associated with great costs for individuals, companies and society at large. Influenced by neo-classical economic theory, policy advice has emphasized the role of sickness benefit programs for reducing sickness absence rates: too generous benefits without proper control will increase the number of recipients and prolong absence spells as well as possibly cause negative dynamic effects in the long term. This study provides an alternative interpretation of the relationship between sickness benefits and sickness absence. By combining an epidemiological approach to sickness absence and a resource-based approach to welfare, we argue that sickness benefits might be viewed as a "collective resource" that, by providing economic support during times of ill-health, might have positive health effects. Statistical analysis of short-term sickness absence using innovative methodological approaches and combined micro- and macro-level data for 21 EU countries over the period of 1992-2011 indicates that the long run effects of relatively generous sickness benefits is rather to reduce sickness absence. This result also has implications for sickness benefit reform: whereas benefit cuts to some extent may reduce absence in the short run, in the longer run such reforms may actually increase sickness absence rates.

Spacelab experiments on space motion sickness

1987-01-01

Recent research results from ground and flight experiments on motion sickness and space sickness conducted by the Man Vehicle Laboratory are reviewed. New tools developed include a mathematical model for motion sickness, a method for quantitative measurements of skin pallor and blush in ambulatory subjects, and a magnitude estimation technique for ratio scaling of nausea or discomfort. These have been used to experimentally study the time course of skin pallor and subjective symptoms in laboratory motion sickness. In prolonged sickness, subjects become hypersensitive to nauseogenic stimuli. Results of a Spacelab-1 flight experiment are described in which four observers documented the stimulus factors for and the symptoms/signs of space sickness. The clinical character of space sickness differs somewhat from acute laboratory motion sickness. However SL-1 findings support the view that space sickness is fundamentally a motion sickness. Symptoms were subjectively alleviated by head movement restriction, maintenance of a familiar orientation with respect to the visual environment, and wedging between or strapping onto surfaces which provided broad contact cues confirming the absence of body motion.

Betwixt and between: workplace perspectives on work reintegration in the eldercare sector in Denmark.

Contemporary return-to-work (RTW) policies in Denmark and other welfare nations recommend employees on long-term sick leave, due to physical or mental health problems, to RTW gradually. Factors that influence the process of work reintegration (WR) is well documented, however, co-workers experiences of this process are a rather new research topic. Moreover, in the context of the present research, no studies have so far explored the workplace as an arena for social interaction. The aim of this study was to explore co-workers' experiences of the reintegration process and how these experiences are related to social positions at the workplace. Ethnographic fieldwork was conducted at two nursing homes that were in a process WR after long-term sick leave. The data consist of field notes, policy documents, individual interviews, and focus group interviews. Data were organized by use of NVivo. A theoretical framework was adopted which enabled us to approach and interpret the reintegration process as one that changed the social position of the returning employee. The dataset demonstrates how the returnee is in a state of being betwixt and between the social positions of a co-worker and a non-co-worker. This is illustrated in three cases which show that this state prevents the returnee from taking on the role as a co-worker, excludes the returnee from the workplace, and creates uncertainty for all workplace actors. The study highlighted that WR creates a social position for the returnee that complicates the working routine and causes uncertainty in social interactions. Implications for Rehabilitation Work reintegration (WR) after long-term sick leave is commonly characterized by reduced working hours and modified working tasks. The WR process influences the whole work place including co-workers' everyday working life and complicates work situations where work tasks and roles are negotiated between the returning worker and co-workers. Future WR policies and guidelines could benefit from integrating co-workers' perspective to ensure that the returning worker is not socially excluded as well as ensuring that co-workers are not overburdened in the process.

[Income reduction due to sickness benefits--when does sickness make you poor?].

PubMed

Mielck, A; Huber, C A

2005-01-01

When absent from work due to sickness, most employees in Germany receive continued pay from their employer for six weeks. After this period, sick employees receive sickness benefits from their Statutory Sickness Fund. These sickness benefits are calculated in a rather complicated way as a percentage of gross and net salary. The paper focuses on two questions that have rarely been studied: which income groups show a particularly large difference between net salary and net sickness benefits? Which income groups move below the poverty line after receiving sickness benefits? We calculated how much sickness benefit is actually paid to the insured, for different income and tax groups. The definition for the poverty line is outlined as well. Due to methodological difficulties, the comparison between sickness benefits and poverty must be confined to single-person households. In the income groups chosen here (gross salary up to 4000 Euro per month), net sickness benefits amount to about 77 % of net salary, for all insured. Financial problems can mainly be expected for the lower and the upper income groups. Expressed in absolute terms, the upper income groups experience a large reduction in net income. The lower income groups come close to the poverty line or fall below it. Sickness benefits provide income in case of sickness; this is an important achievement of social policy. However, we should study the financial burden which sickness benefits could have for the insured. More in-depth analyses would require data that are not yet available (e. g. on the number of insured per income group and the income of other household members). The analyses presented here already show that sickness benefits could lead to severe financial problems for at least some insured. They point to the need for more studies in this neglected field.

Sickness absence at a young age and later sickness absence, disability pension, death, unemployment and income in native Swedes and immigrants.

Sickness absence with cash benefits from the sickness insurance gives an opportunity to be relieved from work without losing financial security. There are, however, downsides to taking sickness absence. Periods of sickness absence, even short ones, can increase the risk for future spells of sickness absence and unemployment. The sickness period may in itself have a detrimental effect on health. The aim of the study was to investigate if there is an association between exposure to sickness absence at a young age and later sickness absence, disability pension, death, unemployment and income from work. Our cohort consisted of all immigrants aged 21-25 years in Sweden in 1993 (N = 38 207) and a control group of native Swedes in the same age group (N = 225 977). We measured exposure to sickness absence in 1993 with a follow-up period of 15 years. We conducted separate analyses for men and women, and for immigrants and native Swedes. Exposure to ≥60 days of sickness absence in 1993 increased the risk of sickness absence [hazard ratio (HR) 1.6-11.4], unemployment (HR 1.1-1.2), disability pension (HR 1.2-5.3) and death (HR 1.2-3.5). The income from work, during the follow-up period, among individuals with spells of sick leave for ≥60 days in 1993 was around two-thirds of that of the working population who did not take sick leave. Individuals on sickness absence had an increased risk for work absence, death and lower future income. © The Author 2015.

The Unified Dyskinesia Rating Scale (UDysRS) has been introduced as a comprehensive rating tool for the evaluation of dyskinesias in Parkinson's disease (PD). To enhance a uniform application, we developed a DVD-based training program with instructions, patient examples, and a certification exercise. For training on the objective assessment of dyskinesia, seventy PD patients spanning the gamut of dyskinesias (none to severe) were videotaped during four tasks of daily living (speaking, drinking from a cup, putting on a coat, and walking). Dyskinesia severity in seven body parts was rated by 20 international movement disorder specialists using the UDysRS for impairment. Each task was also rated for disability. Inter-rater reliability was assessed with generalized weighted kappa and intraclass correlation coefficients. For the teaching program, examples of each severity level and each body part were selected based on the criterion that they received a uniform rating (+/- 1 point) by at least 75% of the raters. For the certification exercise, four cases were selected to represent the four quartiles of overall objective UDysRS scores to reflect slight, mild, moderate, and severe dyskinesia. Each selection was based on the highest inter-rater reliability score for that quartile (minimum kappa or intraclass correlation coefficient = 0.6). UDysRS ranges for certification were calculated based on the 95% confidence interval. The teaching program lasts 41 min, and the certification exercise requires 10 min (total 51 min). This training program, based on visual examples of dyskinesia and anchored in scores generated by movement disorder experts is aimed at increasing homogeneity of ratings among and within raters and centers. Large-scale multicenter randomized clinical trials of dyskinesia treatment are strengthened by a uniform standard of scale application. 2009 Movement Disorder Society.

Background and objective A comparison of sick leave in pregnancy between countries is difficult as most studies have been conducted in single countries in Scandinavia. The objective of this study was to explore patterns of and reasons for sick leave during pregnancy on a multinational level, focusing on medication use but also differences in sick leave policies. Design and setting Cross-sectional, web-based study in 12 European countries from October 2011 to February 2012. Data were collected via an electronic questionnaire. Participants Pregnant women and mothers of children under the age of 1 year. Primary outcome measure Sick leave prevalence in pregnancy. Results Of 6686 women included, 3385 (50.6%) had been on sick leave during pregnancy. The rates of sick leave varied across countries, ranging from 31.7%–34.8% in Sweden and the UK to 62.4%–71.3% in Norway, Serbia, Croatia and Poland. The most common reasons for being on sick leave were pregnancy complications (26.5%); pain in the neck, back or pelvic girdle (16.2%); and nausea and vomiting (NVP, 16.0%). Women using medications for acute illnesses were more likely to be on sick leave than their non-medicated counterparts, while an opposite trend was observed for women with chronic disorders, where non-medicated women were more likely to be on sick leave. Women from countries with ‘low’ sick leave policies were less likely to have extensions of sick leaves compared with women from countries with ‘medium’ policies (adjusted OR 0.63, 95% CI 0.49 to 0.82). Conclusion The rates of sick leave in pregnancy vary greatly across European countries. Women using medications were more likely to be on sick leave, especially for acute illnesses. The differences in sick leave patterns across countries only partially reflected differences in sick leave policies, which implies that sick leave in pregnancy is also affected by other national differences.

Depression is associated with work absenteeism, reduced productivity, and significant personal and societal economic burden. We describe patterns and determinants of sick leave among working Danish antidepressant users. Persons starting antidepressant treatment (January 1, 2004 through December 31, 2005) were identified from a representative 25% sample of the Danish population by linking Danish national registries. Inclusion criteria were age 18-64 years, being in the workforce the week prior to the first antidepressant prescription (index prescription, IP), and no antidepressant prescription in the year prior to the IP. Only sick leaves >2 weeks are centrally registered in Denmark and could be assessed. Cox regression analyses identified predictors of sick leave during the year following the IP, based on previous history of sick leave and clinical and socio-demographic baseline characteristics. In the cohort of 25,908 (59.7% women), sick leave prevalence increased from 37.5% (year prior to IP) to 45.3% (year after the IP); 30.7% were on sick leave for >8 weeks. Incidence peaked (35.5% of individuals) the week after the IP. Of persons with sick leave in the year before the IP, 62.7% were on sick leave the first week after the IP, vs 5.7% of those without previous sick leave. Predictors associated with increased risk of sick leave among those without previous sick leave were unemployment, female gender, age 25-54 years, couples with children, and vocational and higher intermediate education (including e.g. teachers and nurses). Reasons for sick leave, sick leaves of less than 14 days and the indications for antidepressant treatment were unknown. Sick leave was prevalent in persons starting new antidepressant use, often lasting >8 weeks. Previous sick leave was the strongest predictor of subsequent sick leave. © 2013 Elsevier B.V.

To assess quality of the national Integrated Management of Childhood Illness (IMCI) program services provided for sick children at primary health facilities in Afghanistan. Mixed methods including cross-sectional study. Thirteen (of thirty-four) provinces in Afghanistan. Observation of case management and re-examination of 177 sick children, exit interviews with caretakers and review of equipment/supplies at 44 health facilities. Introduction and scale up of Integrated Management of Childhood Illnesses at primary health care facilities. Care of sick children according to IMCI guidelines, health worker skills and essential health system elements. Thirty-two (71%) of the health workers were trained in IMCI and five (11%) received supervision in clinical case management during the past 6 months. On average, 5.4 out of 10 main assessment tasks were performed during cases observed, the index being higher in children seen by trained providers than untrained (6.3 vs 3.5, 95% CI 5.8-6.8 vs 2.9-4.1). In all, 74% of the 104 children who needed oral antibiotics received prescriptions, while 30% received complete and correct advice and 30% were overprescribed, and more so by untrained providers. Home care counseling was associated with provider training status (41.3% by trained and 24.5% by untrained). Essential oral and pre-referral injectable medicine and equipment/supplies were available in 66%, 23%, and 45% of health facilities, respectively. IMCI training improved assessment, rational use of antibiotics and counseling; further investment in IMCI in Afghanistan, continuing provider capacity building and supportive supervision for improved quality of care and counseling for sick children is needed, especially given high burden treatable childhood illness. © The Author 2016.

KENNEDY SPACE CENTER, FLA. - Jack Wilcox (at the microphone) answers questions from the media during a reunion with his rescuers at the Hangar AF docks, Cape Canaveral Air Force Station. At right is his wife, Patty. Wilcox reunited with the men aboard KSC's Freedom Star SRB retrieval ship that was in the vicinity when Wilcox suffered decompression sickness on a diving expedition 20 miles off shore in the Atlantic Ocean. When the Freedom Star team heard the call for help, they asked the Coast Guard if they could assist. The ship was out on a crane certification exercise and coincidentally had a diver medical technician and other divers training on the crane. The ship's divers were trained for the hyperbaric chamber on board. Upon reaching the Army dock, KSC Occupational Health physician Skip Beeler entered the chamber and continued the process of helping to stabilize Wilcox. After several hours in the chamber, Wilcox, who lives in Orlando, was airlifted to Florida Hospital Orlando.

Exposure to shift work has been associated with negative health consequences, although the association between shift work and sickness absence remains unclear. The aim of this study is to investigate associations between cumulative exposure to shift work and sickness absence among ground staff employees of an airline company. This study used data from the MORE (Monitoring Occupational Health Risks in Employees) cohort, which is a 5-year historic cohort. The population of the present study consisted of 7562 ground staff employees. For each employee, work schedules and sickness absence days between 2005 and 2009 were obtained from company records. For the exposure to different shift schedule types and to the cumulative number of night shifts, the association with long-term sickness absence (>7 consecutive sickness absence days) and the number of sickness absence episodes during 2009, was calculated using logistic and Poisson regression analyses. Socio-demographic variables, work-related variables, job classification variables, and previous sickness absence days were regarded as confounders. After adjusting for previous sickness absence and job classification variables, only the group of employees that switched into working in a three-shift schedule, showed a significantly increased risk for long-term sickness absence (OR = 1.31, 95%CI 1.02-1.69). Night shift exposure was not significantly associated with long-term sickness absence. Exposure to shift work was negatively associated with more sickness absence episodes. Employees who were exposed to more than 46 night shifts also showed a lower risk for more sickness absence episodes. Subgroup analyses showed that single employees and employees without children had an increased risk for long-term sickness absence when exposed to a three-shift schedule, and when they had changed between shift schedule types. Cumulative exposure to shift work proved to be negatively associated with more sickness absence episodes, and was not associated with more long-term sickness absence, although selection bias could not be ruled out. Future research should explore the influence of household composition, and take into account both previous sickness absence and psychosocial and physical work factors to obtain a better estimation of the association between shift work and sickness absence.

Implementing and Evaluating a National Certification Technical Skills Examination: The Colorectal Objective Structured Assessment of Technical Skill.

2016-07-01

To implement the Colorectal Objective Structured Assessment of Technical skill (COSATS) into American Board of Colon and Rectal Surgery (ABCRS) certification and build evidence of validity for the interpretation of the scores of this high stakes assessment tool. Currently, technical skill assessment is not a formal component of board certification. With the technical demands of surgical specialties, documenting competence in technical skill at the time of certification with a valid tool is ideal. In September 2014, the COSATS was a mandatory component of ABCRS certification. Seventy candidates took the examination, with their performance evaluated by expert colorectal surgeons using a task-specific checklist, global rating scale, and overall performance scale. Passing scores were set and compared using 2 standard setting methodologies, using a compensatory and conjunctive model. Inter-rater reliability and the reliability of the pass/fail decision were calculated using Cronbach alpha and Subkoviak methodology, respectively. Overall COSATS scores and pass/fail status were compared with results on the ABCRS oral examination. The pass rate ranged from 85.7% to 90%. Inter-rater reliability (0.85) and reliability of the pass/fail decision (0.87 and 0.84) were high. A low positive correlation (r= 0.25) was seen between the COSATS and oral examination. All individuals who failed the COSATS passed the ABCRS oral examination. COSATS is the first technical skill examination used in national surgical board certification. This study suggests that the current certification process may be failing to identify individuals who have demonstrated technical deficiencies on this standardized assessment tool.

Suborbital Safety Technical Committee- Summary of Proposed Standards & Guidelines

2013-09-01

There are currently no international safety standards and guidelines to assist designers, operators and authorities in the suborbital domain. There is a launch licensing regime in the United States (US) to assist the forerunners of the suborbital domain however this does not provide a safety approval for the vehicle against set standards or does not have an acceptable level of safety to achieve in terms of design or operation. In Europe a certification framework may be implemented however this (or any regulatory framework) is not in place as yet. This paper summarises the 5 tasks thus far completed by the International Association for the Advancement of Space Safety (IAASS) Suborbital Safety Technical Committee (SS TC) in terms of deriving standards and guidelines for the suborbital domain. The SS TC comprises members from the suborbital industry (US and European vehicle designers), safety experts, legal experts, medical/training experts, prospective spaceport operators and members from the US and European authorities (though these members cannot directly steer the standards and guidelines - they can merely review them for interest and comment on non-policy aspects). The SS TC has been divided into three working groups (WG): Regulatory WG, Technical WG and Operations WG. The 5 tasks that are summarised in this paper include: Regulatory WG - (Task 1) Clarify and promote regulatory framework for suborbital flights (including discussions on Space Law 'v' Air Law for suborbital domain); Technical WG - (Task 1) Defining & Alignment (globally) of Safety Criteria for Suborbital domain using industry best practices, (Task 2) Software/complex hardware certification for suborbital flights; Operations WG - (Task 1) Flight Crew and Spaceflight Participant Medical and Training Standards & Guidelines for suborbital flight, (Task 2) Spaceport Safety Management System. This paper also details the next set of standards and guidelines that will be derived by the SS TC. The paper concludes that these and future IAASS suborbital safety standards and guidelines are needed now and should beconsidered by the industry players before the first commercial flights expected late 2013/early 2014.

2010-05-01

To meet the increasing demand for healthcare providers, it is crucial to recruit and retain more nurse anaesthetists (NAs). The majority of NAs in the Netherlands are >45 years old, and retaining them in their jobs is very important. This study investigates the relationships among burnout, physical health and job satisfaction among Dutch NAs. Two thousand NAs working in Dutch hospitals were invited to participate in this online questionnaire. We tested the relationships among burnout, psychosomatic symptoms, sickness absence, perceived general health and job satisfaction. Nine hundred and twenty-three questionnaires were completed and analysed (46% response rate). Burnout and psychosomatic symptoms were negatively associated with job satisfaction, and predicted 27% of job satisfaction. Perceived general health was positively and sickness absence was negatively related to job satisfaction. Older NAs had a higher incidence of burnout than their younger counterparts. The results confirmed the importance of a healthy psychosocial work environment for promoting job satisfaction. To prevent burnout, further research is necessary to determine the factors causing stress. These findings may also apply to anaesthesiologists who share many tasks and work in close cooperation with NAs.

To examine the relation between work-family conflict and sickness absence. The BELSTRESS III study comprised 2983 middle-aged workers. Strain-based work-home interference (WHI) and home-work interference (HWI) were assessed by means of self-administered questionnaires. Prospective data of registered sickness absence during 12-months follow-up were collected. Multiple logistic regression analysis was conducted. HWI was positively and significantly related to high sickness absence duration (at least 10 sick leave days) and high sickness absence frequency (at least 3 sick leave episodes) in men and women, also after adjustments were made for sociodemographic variables, health indicators, and environmental psychosocial factors. In multivariate analysis, no association between WHI and sickness absence was found. HWI was positively and significantly related to high sickness absence duration and frequency during 12-months follow-up in male and female workers.

Are environmental characteristics in the municipal eldercare, more closely associated with frequent short sick leave spells among employees than with total sick leave: a cross-sectional study.

It has been suggested that frequent-, short-term sick leave is associated with work environment factors, whereas long-term sick leave is associated mainly with health factors. However, studies of the hypothesis of an association between a poor working environment and frequent short spells of sick leave are few and results are inconsistent. Therefore, we aimed to explore associations between self-reported psychosocial work factors and workplace-registered frequency and length of sick leave in the eldercare sector. Employees from the municipal eldercare in Aarhus (N = 2,534) were included. In 2005, they responded to a work environment questionnaire. Sick leave records from 2005 were dichotomised into total sick leave days (0-14 and above 14 days) and into spell patterns (0-2 short, 3-9 short, and mixed spells and 1-3 long spells). Logistic regression models were used to analyse associations; adjusted for age, gender, occupation, and number of spells or sick leave length. The response rate was 76%; 96% of the respondents were women. Unfavourable mean scores in work pace, demands for hiding emotions, poor quality of leadership and bullying were best indicated by more than 14 sick leave days compared with 0-14 sick leave days. For work pace, the best indicator was a long-term sick leave pattern compared with a non-frequent short-term pattern. A frequent short-term sick leave pattern was a better indicator of emotional demands (1.62; 95% CI: 1.1-2.5) and role conflict (1.50; 95% CI: 1.2-1.9) than a short-term non-frequent pattern.Age (= < 40 / >40 years) statistically significantly modified the association between the 1-3 long-term sick leave spell pattern and commitment to the workplace compared with the 3-9 frequent short-term pattern. Total sick leave length and a long-term sick leave spell pattern were just as good or even better indicators of unfavourable work factor scores than a frequent short-term sick leave pattern. Scores in commitment to the workplace and quality of leadership varied with sick leave pattern and age. Thus, different sick leave measures seem to be associated with different work environment factors. Further studies on these associations may inform interventions to improve occupational health care.

Motion sickness incidence during a round-the-world yacht race.

PubMed

Turner, M; Griffin, M J

1995-09-01

Motion sickness experiences were obtained from participants in a 9 month, round the world yacht race. Race participants completed questionnaires on their motion sickness experience 1 week prior to the start of the race, during the race, and following the race. Yacht headings, sea states, and wind directions were recorded throughout the race. Illness and the occurrence of vomiting were related to the duration at sea and yacht encounter directions relative to the prevailing wind. Individual crewmember characteristics, the use of anti-motion sickness drugs, activity while at sea, and after-effects of yacht motion were also examined with respect to sickness occurrence. Sickness was greatest among females and younger crewmembers, and among crewmembers who used anti-motion sickness drugs. Sickness varied as a function of drug type and activity while at sea. Crewmembers who reported after-effects of yacht motion also reported greater sickness while at sea. The primary determinants of motion sickness were the duration of time spent at sea and yacht encounter direction to the prevailing wind.

2015-06-01

Socioeconomic differences in sickness absence are well established among middle-aged employees but poorly known among younger employees, in particular for shorter spells. We examined trends in occupational class differences in short sickness absence among young women. The data were obtained from the registers of the City of Helsinki, Finland, and included female employees aged 18-34 years from 2002 to 2013. Self-certified (1-3 days) sickness absence spells were examined. Occupational class was classified into four hierarchical categories. Joinpoint regression models were used to identify major changes in sickness absence trends. Short sickness absence increased until 2008, after which it decreased in all occupational classes except manual workers. Differences in sickness absence between occupational classes remained over time. Routine non-manuals had the highest amount of short sickness absence, while managers and professionals had the smallest amount. Manual workers had somewhat less short sickness absence than routine non-manuals and semi-professionals. The socioeconomic differences in short sickness absence were clear among young women but not fully consistent as routine non-manuals tended to have more sickness absence than manual workers. Preventive measures are needed to narrow socioeconomic differences in young women's sickness absence especially among routine non-manuals. © 2015 the Nordic Societies of Public Health.

Hand surgeons are faced with the impossible task of mastering a rapidly expanding pool of knowledge and surgical techniques. Dedication to lifelong learning is, therefore, an essential component of delivering the best, most up-to-date care for patients. Board certification, participation in continuing medical education and maintenance of certification activities, and attendance at national meetings are essential mechanisms by which hand surgeons may foster the acquisition of essential knowledge and clinical skills, This article highlights the history, current status, and emerging needs in continuing medical education for the hand surgeon.

Training complexity is not decisive factor for improving adaptation to visual sensory conflict.

2012-01-01

Ground-based preflight training utilizing unusual visual stimuli is useful for decreasing the susceptibility to space motion sickness (SMS). The effectiveness of the sensorimotor adaptation training is affected by the training tasks, but what kind of task is more effective remains unknown. Whether the complexity is the decisive factor to consider for designing the training and if other factors are more important need to be analyzed. The results from the analysis can help to optimize the preflight training tasks for astronauts. Twenty right-handed subjects were asked to draw the right path of 45° rotated maze before and after 30 min training. Subjects wore an up-down reversing prism spectacle in test and training sessions. Two training tasks were performed: drawing the right path of the horizontal maze (complex task but with different orientation feature) and drawing the L-shape lines (easy task with same orientation feature). The error rate and the executing time were measured during the test. Paired samples t test was used to compare the effects of the two training tasks. After each training, the error rate and the executing time were significantly decreased. However, the training effectiveness of the easy task was better as the test was finished more quickly and accurately. The complexity is not always the decisive factor for designing the adaptation training task, e.g. the orientation feature is more important in this study. In order to accelerate the adaptation and to counter SMS, the task for astronauts preflight adaptation training could be simple activities with the key features.

Quality assurance and risk management: Perspectives on Human Factors Certification of Advanced Aviation Systems

NASA Technical Reports Server (NTRS)

Taylor, Robert M.; Macleod, Iain S.

1994-01-01

This paper is based on the experience of engineering psychologists advising the U.K. Ministry of Defense (MoD) on the procurement of advanced aviation systems that conform to good human engineering (HE) practice. Traditional approaches to HE in systems procurement focus on the physical nature of the human-machine interface. Advanced aviation systems present increasingly complex design requirements for human functional integration, information processing, and cognitive task performance effectiveness. These developing requirements present new challenges for HE quality assurance (QA) and risk management, requiring focus on design processes as well as on design content or product. A new approach to the application of HE, recently adopted by NATO, provides more systematic ordering and control of HE processes and activities to meet the challenges of advanced aircrew systems design. This systematic approach to HE has been applied by MoD to the procurement of mission systems for the Royal Navy Merlin helicopter. In MoD procurement, certification is a judicial function, essentially independent of the service customer and industry contractor. Certification decisions are based on advice from MoD's appointed Acceptance Agency. Test and evaluation (T&E) conducted by the contractor and by the Acceptance Agency provide evidence for certification. Certification identifies limitations of systems upon release to the service. Evidence of compliance with HE standards traditionally forms the main basis of HE certification and significant non-compliance could restrict release. The systems HE approach shows concern for the quality of processes as well as for the content of the product. Human factors certification should be concerned with the quality of HE processes as well as products. Certification should require proof of process as well as proof of content and performance. QA criteria such as completeness, consistency, timeliness, and compatibility provide generic guidelines for progressive acceptance and certification of HE processes. Threats to the validity of certification arise from problems and assumptions in T&E methods. T&E should seek to reduce the risk of specification non-compliance and certification failure.

Background Grid technology is the computing model which allows users to share a wide pletora of distributed computational resources regardless of their geographical location. Up to now, the high security policy requested in order to access distributed computing resources has been a rather big limiting factor when trying to broaden the usage of Grids into a wide community of users. Grid security is indeed based on the Public Key Infrastructure (PKI) of X.509 certificates and the procedure to get and manage those certificates is unfortunately not straightforward. A first step to make Grids more appealing for new users has recently been achieved with the adoption of robot certificates. Methods Robot certificates have recently been introduced to perform automated tasks on Grids on behalf of users. They are extremely useful for instance to automate grid service monitoring, data processing production, distributed data collection systems. Basically these certificates can be used to identify a person responsible for an unattended service or process acting as client and/or server. Robot certificates can be installed on a smart card and used behind a portal by everyone interested in running the related applications in a Grid environment using a user-friendly graphic interface. In this work, the GENIUS Grid Portal, powered by EnginFrame, has been extended in order to support the new authentication based on the adoption of these robot certificates. Results The work carried out and reported in this manuscript is particularly relevant for all users who are not familiar with personal digital certificates and the technical aspects of the Grid Security Infrastructure (GSI). The valuable benefits introduced by robot certificates in e-Science can so be extended to users belonging to several scientific domains, providing an asset in raising Grid awareness to a wide number of potential users. Conclusion The adoption of Grid portals extended with robot certificates, can really contribute to creating transparent access to computational resources of Grid Infrastructures, enhancing the spread of this new paradigm in researchers' working life to address new global scientific challenges. The evaluated solution can of course be extended to other portals, applications and scientific communities. PMID:19534747

Autogenic feedback training experiment: A preventative method for space motion sickness

NASA Technical Reports Server (NTRS)

Cowings, Patricia S.

1993-01-01

Space motion sickness is a disorder which produces symptoms similar to those of motion sickness on Earth. This syndrome has affected approximately 50 percent of all astronauts and cosmonauts exposed to microgravity in space, but it differs from what is commonly known as motion sickness in a number of critical ways. There is currently no ground-based method for predicting susceptibility to motion sickness in space. Antimotion sickness drugs have had limited success in preventing or counteracting symptoms in space, and frequently caused debilitating side effects. The objectives were: (1) to evaluate the effectiveness of Autogenic-Feedback Training as a countermeasure for space motion sickness; (2) to compare physiological data and in-flight symptom reports to ground-based motion sickness data; and (3) to predict susceptibility to space motion sickness based on pre-flight data of each treatment group crew member.

An adequate approach to sickness absence can reduce school dropout which is a major problem in Intermediate Vocational Education (IVE). This practice-based study explores the sickness absence reasons and factors influencing reporting the sickness, from a student's perspective. Semistructured interviews were held until saturation. Data were collected and analysed by a multidisciplinary research team including youth health care physicians working with IVE students. The results show that, according to the students, reasons for sickness reporting were health-related or related to problems at home or in school. Students view their sickness absence as necessity, as asking for understanding, or as pardonable. Their views depended on (1) the perception of medical legitimacy, (2) feeling able to take their own responsibility, (3) feeling being taken seriously at school, and (4) the perception that the sickness reporting procedure at school is anonymous and easy. In conclusion, reporting sickness seems more a reaction to a necessity or opportunity than the result of a conscious decision-making process. Personalizing the sickness reporting procedures and demonstrating interest rather than control while discussing the sickness absence with the individual IVE student might very well affect their sickness absence levels.

To determine the demographic and work characteristics of healthcare workers who were more likely to take sickness absences from work in British Columbia, Canada. Payroll data were analyzed for three health regions. Sickness absence rates were determined per person-year and then compared across demographic and work characteristics using multivariate Poisson regression models. The direct costs to the employer due to sickness absences were also estimated. Female, older, full-time workers, long-term care workers and those with a lower hourly wage were more likely to take sickness absences and had similar trends with respect to the costs due to sickness absence. For occupations, licensed practical nurses, care aides and facility support workers had higher rates of sickness absence. Registered nurses, and those workers paid high hourly wages were associated with highest sickness related costs. It is important to understand the demographic and work characteristics of those workers who are more likely to take sickness absences in order to make sure that they are not experiencing additional hazards at work or facing detrimental workplace conditions. Policy makers need to establish healthy, safe and in turn more productive workplaces. Further research is needed on how interventions can reduce sickness absence.

Little is known regarding incidence and recurrence of sickness absence in self-employed. The primary aim of this study was to evaluate the influence of the number of prior episodes of sickness absence on the risk of subsequent periods of sickness absence in higher educated self-employed. In a historic register study based on the files of a Dutch private disability insurance company all sickness absence periods of 30 days or more were analysed. A total of 15,868 insured persons contributed 141,188 person years to the study. In total, 5608 periods of sickness absence occurred during follow-up. The hazard of experiencing a new period of sickness absence increased with every previous period, ranging from a hazard ratio of 2.83 in case of one previous period of sickness absence to a hazard ratio of 6.72 in case of four previous periods. This effect was found for both men and women and for all diagnostic categories of the first period of sickness absence. Our study shows that for all diagnostic categories the hazard of experiencing a recurrence of sickness absence is appreciably higher than for experiencing a first episode. This suggests that this increased hazard may be related to the occurrence of sickness absence itself rather than related to characteristics of the insured person or of the medical condition. These findings could indicate that sickness absence periods may have a scarring effect on the self-employed person experiencing the sickness absence.

This study examined factors associated with being paid for sick leave after implementation of the New York City (NYC) paid sick leave law. A random sample of NYC residents was surveyed by telephone multiple times over a 2-year period. Participants (n = 1195) reported socio-demographics, awareness of the law, income, work hours per week, and payment for sick time off work. In the year after implementation of the law, part-time workers were significantly more likely to attend work while sick than full-time workers (relative risk = 1.25, 95% CI = 1.1, 1.4). Seventy percent of workers who missed work due to illness (n = 249) were paid for sick leave. Part-time workers, respondents not aware of the benefit (30% of workers), and workers without a college degree were the least likely to be paid for sick days. More than one third (37%) of persons not paid for sick leave worked in retail, food service, or health care. Although 70% of respondents were paid for sick leave after implementation of the law, part-time workers and workers with low education were least likely to access the benefit and more likely to work while sick. The disparity in paid sick leave may have public health consequences as many persons not paid for sick leave had occupations that carry a high risk of disease transmission to others.

A comparison of sick leave in pregnancy between countries is difficult as most studies have been conducted in single countries in Scandinavia. The objective of this study was to explore patterns of and reasons for sick leave during pregnancy on a multinational level, focusing on medication use but also differences in sick leave policies. Cross-sectional, web-based study in 12 European countries from October 2011 to February 2012. Data were collected via an electronic questionnaire. Pregnant women and mothers of children under the age of 1 year. Sick leave prevalence in pregnancy. Of 6686 women included, 3385 (50.6%) had been on sick leave during pregnancy. The rates of sick leave varied across countries, ranging from 31.7%-34.8% in Sweden and the UK to 62.4%-71.3% in Norway, Serbia, Croatia and Poland. The most common reasons for being on sick leave were pregnancy complications (26.5%); pain in the neck, back or pelvic girdle (16.2%); and nausea and vomiting (NVP, 16.0%). Women using medications for acute illnesses were more likely to be on sick leave than their non-medicated counterparts, while an opposite trend was observed for women with chronic disorders, where non-medicated women were more likely to be on sick leave. Women from countries with 'low' sick leave policies were less likely to have extensions of sick leaves compared with women from countries with 'medium' policies (adjusted OR 0.63, 95% CI 0.49 to 0.82). The rates of sick leave in pregnancy vary greatly across European countries. Women using medications were more likely to be on sick leave, especially for acute illnesses. The differences in sick leave patterns across countries only partially reflected differences in sick leave policies, which implies that sick leave in pregnancy is also affected by other national differences. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

The Department of General physics and nuclear fusion, National Research University “Moscow Power Engineering Institute”, developed a set of tests (over 1000 questions) for the current control of knowledge of students in the section “Electricity and magnetism” of the General physics course using the internet distance learning system “Prometheus” (fourth generation). Under this section of the proposed test tasks are divided into sections corresponding to the topics section. These tasks include quality issues, design tasks, tasks with a choice of answers (one of many, many of many), the job with the selection region in the figure, tasks with detailed answer. The variety of tasks allows the teacher not only to objectively assess the student acquired knowledge but also to develop his problem-solving skills, to learn to be fluent in theory. The results of testing conducted for several years, show the high interest of students in the repeated independent execution of tasks and correlate well with the results of intermediate certification (exams).

Feasibility of a walking virtual reality system for rehabilitation: objective and subjective parameters.

2016-08-09

Even though virtual reality (VR) is increasingly used in rehabilitation, the implementation of walking navigation in VR still poses a technological challenge for current motion tracking systems. Different metaphors simulate locomotion without involving real gait kinematics, which can affect presence, orientation, spatial memory and cognition, and even performance. All these factors can dissuade their use in rehabilitation. We hypothesize that a marker-based head tracking solution would allow walking in VR with high sense of presence and without causing sickness. The objectives of this study were to determine the accuracy, the jitter, and the lag of the tracking system and its elicited sickness and presence in comparison of a CAVE system. The accuracy and the jitter around the working area at three different heights and the lag of the head tracking system were analyzed. In addition, 47 healthy subjects completed a search task that involved navigation in the walking VR system and in the CAVE system. Navigation was enabled by natural locomotion in the walking VR system and through a specific device in the CAVE system. An HMD was used as display in the walking VR system. After interacting with each system, subjects rated their sickness in a seven-point scale and their presence in the Slater-Usoh-Steed Questionnaire and a modified version of the Presence Questionnaire. Better performance was registered at higher heights, where accuracy was less than 0.6 cm and the jitter was about 6 mm. The lag of the system was 120 ms. Participants reported that both systems caused similar low levels of sickness (about 2.4 over 7). However, ratings showed that the walking VR system elicited higher sense of presence than the CAVE system in both the Slater-Usoh-Steed Questionnaire (17.6 ± 0.3 vs 14.6 ± 0.6 over 21, respectively) and the modified Presence Questionnaire (107.4 ± 2.0 vs 93.5 ± 3.2 over 147, respectively). The marker-based solution provided accurate, robust, and fast head tracking to allow navigation in the VR system by walking without causing relevant sickness and promoting higher sense of presence than CAVE systems, thus enabling natural walking in full-scale environments, which can enhance the ecological validity of VR-based rehabilitation applications.

In Poland conditions related to or aggravated by the pregnancy, childbirth or the puerperium are one of the common causes of sickness absence. The aim of the study was to analyze the occupational activity pattern during pregnancy and to evaluate the determinants of pregnancy-related temporary work disability confirmed by medical certificate. The presented analysis is based on data collected under the Polish Mother and Child Cohort Study. The study population consisted of 954 women who reported occupational activity during pregnancy. All women participating in the study were interviewed 3 times during pregnancy. Detail information on occupational activity during pregnancy and occupational stress, based on the Subjective Work Characteristics Questionnaire, was collected from all women. The pregnant women had been issued medical certificate of temporary work disability because of conditions related to or aggravated by the pregnancy, childbirth or by the puerperium at 16 week of gestation on average and did not continue their activities until the end of pregnancy. The statistically significant determinants of receiving such medical certificate in the first trimester of pregnancy (< or = 12 weeks of pregnancy) comprised poor health condition and complications during pregnancy (OR = 1.4; p = 0.01), lower education (OR = 2.4; p <0.001), socio-economic status (OR = 9.6; p = 0.03), use of public transport to commute to work (OR = 2.7; p <0.001), a longer work commute (OR = 1.4; p = 0.008) and a higher level of occupational stress (OR = 3.0; p < 0.01). Waitresses, nurses and saleswomen received medical certificate of temporary work disability in the first trimester of pregnancy more frequently than office workers (OR = 4.2; p = 0.005; OR = 3.3; p = 0.02; OR = 2.3; p < 0.001 respectively). It is crucial to develop the model of cooperation between occupational medicine physicians and gynecologists and a greater involvement of the former in the prophylactic care of occupationally active pregnant women. It is also important to increase the employers' awareness of potential risks and arduousness at work to assure working conditions safe for the pregnancy outcome and health of both women and their babies.

Does postponement of first pregnancy increase gender differences in sickness absence? A register based analysis of Norwegian employees in 1993-2007.

From 1970-2012, the average age at first delivery increased from 23.2-28.5 in Norway. Postponement of first pregnancy increases risks of medical complications both during and after pregnancy. Sickness absence during pregnancy has over the last two decades increased considerably more than in non-pregnant women. The aim of this paper is twofold: Firstly to investigate if postponement of pregnancy is related to increased sickness absence and thus contributing to the increased gender difference in sickness absence; and secondly, to estimate how much of the increased gender difference in sickness absence that can be accounted for by increased sickness absence amongst pregnant women. We employed registry-data to analyse sickness absence among all Norwegian employees with income equivalent to full-time work in the period 1993-2007. After control for age, education, and income, pregnant women's sickness absence (age 20-44) increased on average 0.94 percentage points each year, compared to 0.29 in non-pregnant women and 0.14 in men. In pregnant women aged 20-24, sickness absence during pregnancy increased by 0.96 percent points per calendar year, compared to 0.60 in age-group 30-34. Sickness absence during pregnancy accounted for 25% of the increased gender gap in sickness absence, accounting for changes in education, income and age. Postponement of first pregnancy does not explain the increase in pregnant women's sickness absence during the period 1993-2007 as both the highest level and increase in sickness absence is seen in the younger women. Reasons are poorly understood, but still important as it accounts for 25% of the increased gender gap in sickness absence.

Long-term sick leave and withdrawal from working life is a concern in western countries. In Norway, comprehensive inpatient work rehabilitation may be offered to sick listed individuals at risk of long-term absence from work. Knowledge about prognostic factors for work outcomes after long-term sick leave and work rehabilitation is still limited. The aim of this study was to test a mediation model for various hypothesized biopsychosocial predictors of continued sick leave after inpatient work rehabilitation. One thousand one hundred fifty-five participants on long-term sick leave from eight different work rehabilitation clinics answered comprehensive questionnaires at arrival to the clinic, and were followed with official register data on sickness benefits for 3 years. Structural equation models were conducted, with days on sickness benefits after work rehabilitation as the outcome. Fear avoidance beliefs for work mediated the relation between both musculoskeletal complaints and education on days on sickness benefits after work rehabilitation. The relation between musculoskeletal complaints and fear avoidance beliefs for work was furthermore fully mediated by poor physical function. Previous sick leave had a strong independent effect on continued sick leave after work rehabilitation. Fear avoidance beliefs for work did not mediate the small effect of pseudoneurological complaints on continued sick leave. Poor coping/interaction ability was neither related to continued sick leave nor fear avoidance beliefs for work. The mediation model was partly supported by the data, and provides some possible new insight into how fear avoidance beliefs for work and functional ability may intervene with subjective health complaints and days on sickness benefits after work rehabilitation.

A method for structured functional assessments of persons with long-term sick leave was implemented in a cluster randomised controlled trial in general practice. The aim was to analyse intervention effects on general practitioner (GP) sick-listing practice and patient sick leave. 57 GPs were randomly assigned to an intervention or a control group. The intervention group GPs learned the method at a 1-day workshop including teamwork and role-playing. The control group GPs were requested to assess functional ability as usual during the 8 months intervention period in 2005. Outcome measures included duration of patient sick leave episodes, GP prescription of part-time sick leave, active sick leave, and vocational rehabilitation. This data was extracted from a national register. The GPs in the intervention group prescribed part-time sick leave more often (p < 0.01) and active sick leave less often (p = 0.04) than the control group GPs during the intervention period. There was no intervention effect on duration of patient sick leave episodes or on GP prescription of vocational rehabilitation. Implementing structured functional assessments in general practice made the GPs capable to assess functional ability of persons with long-term sick leave in a standardised and explicit manner. The intervention GPs' sick-listing practice was changed as they prescribed more part-time and less active sick leave compared to the control group GPs. As a result, more intervention GP patients returned to part-time work compared to control GP patients. No intervention effect was seen on duration of patient sick leave episodes or on prescription of vocational rehabilitation.

Are environmental characteristics in the municipal eldercare, more closely associated with frequent short sick leave spells among employees than with total sick leave: a cross-sectional study

PubMed Central

2013-01-01

Background It has been suggested that frequent-, short-term sick leave is associated with work environment factors, whereas long-term sick leave is associated mainly with health factors. However, studies of the hypothesis of an association between a poor working environment and frequent short spells of sick leave are few and results are inconsistent. Therefore, we aimed to explore associations between self-reported psychosocial work factors and workplace-registered frequency and length of sick leave in the eldercare sector. Methods Employees from the municipal eldercare in Aarhus (N = 2,534) were included. In 2005, they responded to a work environment questionnaire. Sick leave records from 2005 were dichotomised into total sick leave days (0–14 and above 14 days) and into spell patterns (0–2 short, 3–9 short, and mixed spells and 1–3 long spells). Logistic regression models were used to analyse associations; adjusted for age, gender, occupation, and number of spells or sick leave length. Results The response rate was 76%; 96% of the respondents were women. Unfavourable mean scores in work pace, demands for hiding emotions, poor quality of leadership and bullying were best indicated by more than 14 sick leave days compared with 0–14 sick leave days. For work pace, the best indicator was a long-term sick leave pattern compared with a non-frequent short-term pattern. A frequent short-term sick leave pattern was a better indicator of emotional demands (1.62; 95% CI: 1.1-2.5) and role conflict (1.50; 95% CI: 1.2-1.9) than a short-term non-frequent pattern. Age (= < 40 / >40 years) statistically significantly modified the association between the 1–3 long-term sick leave spell pattern and commitment to the workplace compared with the 3–9 frequent short-term pattern. Conclusions Total sick leave length and a long-term sick leave spell pattern were just as good or even better indicators of unfavourable work factor scores than a frequent short-term sick leave pattern. Scores in commitment to the workplace and quality of leadership varied with sick leave pattern and age. Thus, different sick leave measures seem to be associated with different work environment factors. Further studies on these associations may inform interventions to improve occupational health care.

Considering the emerging advantages related to virtual reality implementation in clinical rehabilitation, the aim of the present study was to discover possible (i) improvements achievable in unilateral vestibular hypofunction patients using a self-assessed head-mounted device (HMD)-based gaming procedure when combined with a classical vestibular rehabilitation protocol (HMD group) as compared with a group undergoing only vestibular rehabilitation and (ii) HMD procedure-related side effects. Therefore, 24 vestibular rehabilitation and 23-matched HMD unilateral vestibular hypofunction individuals simultaneously underwent a 4-week rehabilitation protocol. Both otoneurological measures (vestibulo-ocular reflex gain and postural arrangement by studying both posturography parameters and spectral values of body oscillation) and performance and self-report measures (Italian Dizziness Handicap Inventory; Activities-specific Balance Confidence scale; Zung Instrument for Anxiety Disorders, Dynamic Gait Index; and Simulator Sickness Questionnaire) were analyzed by means of a between-group/within-subject analysis of variance model. A significant post-treatment between-effect was found, and the HMD group demonstrated an overall improvement in vestibulo-ocular reflex gain on the lesional side, in posturography parameters, in low-frequency spectral domain, as well as in Italian Dizziness Handicap Inventory and Activities-specific Balance Confidence scale scores. Meanwhile, Simulator Sickness Questionnaire scores demonstrated a significant reduction in symptoms related to experimental home-based gaming tasks during the HMD procedure. Our findings revealed the possible advantages of HMD implementation in vestibular rehabilitation, suggesting it as an innovative, self-assessed, low-cost, and compliant tool useful in maximizing vestibular rehabilitation outcomes.

The durations of past sickness absences predict future absence episodes.

Laaksonen, Mikko; He, Liang; Pitkäniemi, Janne

To determine whether preceding absence episodes increase the risk of future sickness absence, we examined recurrence of short (1 to 3 days), intermediate (4 to 14 days), and long (>2 weeks) sickness-absence episodes. Data from 6934 municipal employees of the City of Helsinki were analyzed using proportional hazards models. Preceding sickness absence increased the risk of new sickness-absence episodes. The association was stronger for longer sickness absence spells and for men. Shorter absence spells also predicted longer absence spells. Working conditions and health behaviors did not modify the associations. The risk of recurrent sickness absences is higher for longer sickness-absence spells, which are often recurrent in nature. In addition, short absence spells predict future longer spells, suggesting that short absences are not trivial for health.

The association between workplace bullying and sickness absence remains unclear. This paper presents a systematic review and meta-analysis of research on the association. We conducted a systematic review and meta-analysis of published primary studies on workplace bullying and sickness absence. Studies based on prospective design or registry data on sickness absence were included. Cross-sectional studies with self-reported sickness absence were excluded. Seventeen primary studies were included in the review, sixteen originated from the Nordic countries and fifteen included registry data on sickness absence. All but one study found that exposure to workplace bullying was associated with increased risk of sickness absence. A meta-analysis of ten independent studies showed that exposure to bullying increased the risk of sickness absence (odds ratio 1.58, 95% CI 1.39-1.79). Five studies included variables that moderated the association between bullying and absenteeism. None of the studies included mediating variables. No studies examined sickness absence as a risk factor for later exposure to bullying. Following the GRADE guidelines, the evidence for an association between bullying and sickness absence is moderate. Workplace bullying is a risk factor for sickness absence, but the mechanisms to explain this relationship are not sufficiently described. It is unclear whether sickness absence predicts later exposure to bullying. While, the methodological quality of the reviewed studies was high, the knowledge base is small. There is a need for more research on how and when bullying is related to sickness absence and the possible bidirectional relationships involved.

Little is known about the prevalence of sick leave due to atopic dermatitis (AD). The current literature on factors influencing sick leave is mostly derived from other chronic inflammatory diseases. This study aimed to determine the prevalence of sick leave due to AD and to identify influencing factors. A cross-sectional study was carried out in adult patients with AD. sick leave during the two-week and one-year periods, socio-demographic characteristics, disease severity, quality of life and socio-occupational factors. Logistic regression analyses were used to determine influencing factors on sick leave over the two-week period. In total, 253 patients were included; 12% of the patients had to take sick leave in the last two weeks due to AD and 42% in the past year. A higher level of symptom interference (OR 1.26; 95% CI 1.13-1.40) or perfectionism/diligence (OR 0.90; 95% CI 0.83-0.96) may respectively increase or decrease the number of sick leave days. Sick leave in patients with AD is a common problem and symptom interference and perfectionism/diligence appeared to influence it. Novel approaches are needed to deal with symptoms at work or school to reduce the amount of sick leave due to AD.

Increased sickness absence in recent years has been a trouble making issue in industrial society. Identify the causes of sickness absence and its influencing factors, is an important step to control and reduce its associated complications and costs. The aim of this study was to evaluate main factors associated with the incidence of sickness absence. In 2012, a cross-sectional study on 758 employees of a car accessories producing company was applied and relevant information about the number of days and episodes of sickness absence, Disease resulting in absence from work, personal features, occupational factors and physical exposures were collected. To determine risk factors associated with sickness absence, Logistic regression analysis was used. The most common diseases leading to sickness absence in order of frequency were Respiratory diseases, musculoskeletal disorders, gastrointestinal diseases and injuries at work. Musculoskeletal disorders increased the danger of long term absence by 4/33 times. Blue collar and shift works were the most important occupational factors associated with the incidence of sickness absence. The main physical factors that affect incidence of sickness absence were frequent bending-twisting and heavy lifting. Identifying controllable factors of sickness absence and trying to prevent and modify them such as compliance of ergonomic principals to decrease physical can be effective in reducing sickness absence.

Parents have always played a critical role in the care of sick children. Although parents' roles remain crucial to children's health, parental availability has declined during the past half century. The percentage of women with preschool children who work has risen almost fivefold in 45 years from 12% in 1947 to 58% in 1992. The percentage of women in the paid work force with school-aged children has almost tripled in the same period, from 27.3% to 75.9%. Research has examined the effects of a variety of parental work conditions on children. However, past research has not examined how working conditions affect the ability of parents to care for their sick children. In this article, we examine how often the children of working parents get sick and whether parents receive enough paid leave to care for their sick children. This analysis makes use of two national surveys, which provide complementary information regarding the care of sick children. The National Longitudinal Survey of Youth is a longitudinal survey of a nationally representative probability sample of 12,686 men and women; the National Medical Expenditure Survey is a panel survey of 34,459 people. First, we estimated the family illness burden. Second, we looked in detail at the number of days of sick leave mothers had. Third, we examined whether mothers who had sick leave had it consistently during a 5-year period. Finally, we conducted a logistic regression to determine what factors were significant predictors of both lacking sick leave. More than one in three families faced a family illness burden of 2 weeks or more each year. Yet, 28% of mothers had sick leave none of the time they were employed between 1985 and 1990. Employed mothers of children with chronic conditions had less sick leave than other employed mothers. Thirty-six percent of mothers whose children had chronic conditions had sick leave none of the time they were employed. Although 20% of working parents who did not live in poverty lacked sick leave, 38% of parents who did live in poverty lacked sick leave. The problem is also more marked for nonwhite parents. Although 23% of working white parents lacked paid sick leave, 31% of nonwhite parents lacked sick leave. One in six families that lacked sick leave had to cover for more than 4 weeks of family illness during the year. In 1993, the US Congress passed the Family and Medical Leave Act (FMLA). However, by limiting the medical leave to the care of major illnesses, primarily those requiring hospitalization, the FMLA does not address the majority of children's sick care needs. For the common childhood illnesses that are not covered by the FMLA, employed parents often must rely on their sick leave if they are to care for their sick children themselves. Yet, we found that many employed parents lack sick leave. This is particularly true of parents of children with chronic conditions and poor and minority families.

Motion sickness and postural sway in console video games.

We tested the hypotheses that (a) participants might develop motion sickness while playing "off-the-shelf" console video games and (b) postural motion would differ between sick and well participants, prior to the onset of motion sickness. There have been many anecdotal reports of motion sickness among people who play console video games (e.g., Xbox, PlayStation). Participants (40 undergraduate students) played a game continuously for up to 50 min while standing or sitting. We varied the distance to the display screen (and, consequently, the visual angle of the display). Across conditions, the incidence of motion sickness ranged from 42% to 56%; incidence did not differ across conditions. During game play, head and torso motion differed between sick and well participants prior to the onset of subjective symptoms of motion sickness. The results indicate that console video games carry a significant risk of motion sickness. Potential applications of this research include changes in the design of console video games and recommendations for how such systems should be used.

Secreted proteases of Trypanosoma brucei gambiense: possible targets for sleeping sickness control?

PubMed

Bossard, Géraldine; Cuny, Gérard; Geiger, Anne

2013-01-01

Human African trypanosomiasis (HAT) is caused by trypanosomes of the species Trypanosoma brucei and belongs to the neglected tropical diseases. Presently, WHO has listed 36 countries as being endemic for sleeping sickness. No vaccine is available, and disease treatment is difficult and has life-threatening side effects. Therefore, there is a crucial need to search for new therapeutic targets against the parasite. Trypanosome excreted-secreted proteins could be promising targets, as the total secretome was shown to inhibit, in vitro, host dendritic cell maturation and their ability to induce lymphocytic allogenic responses. The secretome was found surprisingly rich in various proteins and unexpectedly rich in diverse peptidases, covering more than ten peptidase families or subfamilies. Given their abundance, one may speculate that they would play a genuine role not only in classical "housekeeping" tasks but also in pathogenesis. The paper reviews the deleterious role of proteases from trypanosomes, owing to their capacity to degrade host circulating or structural proteins, as well as proteic hormones, causing severe damage and preventing host immune response. In addition, proteases account for a number of drug targets, such drugs being used to treat severe diseases such AIDS. This review underlines the importance of secreted proteins and especially of secreted proteases as potential targets in HAT-fighting strategies. It points out the need to conduct further investigations on the specific role of each of these various proteases in order to identify those playing a central role in sleeping sickness and would be suitable for drug targeting.

The aims of this study were to observe the sick leave rates of cancer survivors for five consecutive years following a first lifetime diagnosis of invasive cancer and to identify socio-demographic and clinical predictors of sick leave taken in the fifth year after diagnosis. This registry study comprised 2,008 Norwegian individuals (18-61 years old) with their first lifetime diagnosis of invasive cancer in 1999 and alive in 2004 and a cancer-free control group (n = 3,240) matched by sex, age, educational level, and employment status in 1998. Sick leave was defined as at least one sick leave period >16 days within the year in question. A total of 75 % of the long-term cancer survivors (LTCSs) took sick leave within the first 12 months after their diagnosis. The sick leave rate stabilized at a slightly higher level in the following 4 years compared to the year before diagnosis, with approximately 23 % of the male and 31 % of the female LTCSs taking sick leave. Being single with children, having low education, working in health and social work sector, or having taken sick leave the year before diagnosis (1998) predicted the sick leave taken 5 years after diagnosis (2004) among LTCSs. Compared to the controls, LTCSs with rectal, lymphogenic, breast, or "other" types of cancer had significantly higher sick leave rates 5 years after diagnosis. Socio-demographic factors explained more of the variance in sick leave than did clinical factors. Employed LTCSs struggle with their ability to work 5 years after diagnosis. More research is needed to identify factors that would promote LTCSs' health and ability. A socioeconomic and work environmental perspective seems necessary for achieving effective occupational rehabilitation and preventing sick leave among LTCSs.

Hearing difficulties are a large public health problem. Knowledge is scarce regarding risk of disability pension among people who have been sickness absent due to these difficulties. A cohort including all 4,687,756 individuals living in Sweden in 2005, aged 20-64, and not on disability or old-age pension, was followed through 2009. Incidence rate ratios (RR) of disability pension with 95% confidence intervals (CI) were estimated using Cox proportional hazard models. In multivariable models, individuals who had a sick-leave spell due to otoaudiological diagnoses in 2005 had a 1.52-fold (95% CI: 1.43-1.62) increased risk of being granted a disability pension compared to individuals on sick leave due to other diagnoses. Hearing and tinnitus sick-leave diagnoses were associated with risk of disability pension: RR 3.38, 95% CI: 3.04-3.75, and 3.30, 95% CI: 2.95-3.68, respectively. No association was observed between sick leave due to vertigo diagnoses and disability pension whereas otological diagnoses and no sick leave were inversely associated with risk of disability pension compared to non-otoaudiological sick-leave diagnoses. Sick leave due to otoaudiological diagnoses was positively associated with risk of disability pension due to otoaudiological diagnoses and sick leave due to a tinnitus diagnosis was also associated with risk of disability pension due to mental diagnoses. The risk of disability pension among individuals with hearing or tinnitus sick-leave diagnoses was highest in the age group 35-44. Moreover, men had a slightly higher risk. This large cohort study suggests an increased risk of disability pension among those with sickness absence due to otoaudiological diagnoses, particularly hearing and tinnitus diagnoses, compared to those with sickness absence due to non-otoaudiological diagnoses.

Theory of antimotion sickness drug mechanisms.

NASA Technical Reports Server (NTRS)

Wood, D. C.; Graybiel, A.

1972-01-01

The results of a series of antimotion sickness drug evaluations indicates that drugs with central anticholinergic actions and drugs that increase central sympathetic activity are effective against motion sickness. The combination of these actions produces a synergistic effect against motion sickness. The effect of these medications on central acetylcholine or on norepinephrine could alter a balance between the neurons in the vestibular and reticular areas which influence motion sickness and also sympathetic and parasympathetic reactions. It is suggested that this could be their mechanism of action in preventing motion sickness.

EEG-based learning system for online motion sickness level estimation in a dynamic vehicle environment.

PubMed

Lin, Chin-Teng; Tsai, Shu-Fang; Ko, Li-Wei

2013-10-01

Motion sickness is a common experience for many people. Several previous researches indicated that motion sickness has a negative effect on driving performance and sometimes leads to serious traffic accidents because of a decline in a person's ability to maintain self-control. This safety issue has motivated us to find a way to prevent vehicle accidents. Our target was to determine a set of valid motion sickness indicators that would predict the occurrence of a person's motion sickness as soon as possible. A successful method for the early detection of motion sickness will help us to construct a cognitive monitoring system. Such a monitoring system can alert people before they become sick and prevent them from being distracted by various motion sickness symptoms while driving or riding in a car. In our past researches, we investigated the physiological changes that occur during the transition of a passenger's cognitive state using electroencephalography (EEG) power spectrum analysis, and we found that the EEG power responses in the left and right motors, parietal, lateral occipital, and occipital midline brain areas were more highly correlated to subjective sickness levels than other brain areas. In this paper, we propose the use of a self-organizing neural fuzzy inference network (SONFIN) to estimate a driver's/passenger's sickness level based on EEG features that have been extracted online from five motion sickness-related brain areas, while either in real or virtual vehicle environments. The results show that our proposed learning system is capable of extracting a set of valid motion sickness indicators that originated from EEG dynamics, and through SONFIN, a neuro-fuzzy prediction model, we successfully translated the set of motion sickness indicators into motion sickness levels. The overall performance of this proposed EEG-based learning system can achieve an average prediction accuracy of ~82%.

Sick-leave decisions for patients with severe subjective health complaints presenting in primary care: A cross-sectional study in Norway, Sweden, and Denmark

PubMed Central

2013-01-01

Abstract Objectives The primary objective of this study was to explore whether general practitioners (GPs) in Norway, Sweden, and Denmark make similar or different decisions regarding sick leave for patients with severe subjective health complaints (SHC). The secondary objective was to investigate if patient diagnoses, the reasons attributed for patient complaints, and GP demographics could explain variations in sick leave decisions. Design A cross-sectional study. Method Video vignettes of GP consultations with nine different patients. Subjects 126 GPs in Norway, Sweden, and Denmark. Setting Primary care in Norway, Sweden, and Denmark. Main outcome measure Sick leave decisions made by GPs. Results “Psychological” diagnoses in Sweden were related to lower odds ratio (OR) of granting sick leave than in Norway (OR = 0.07; 95% CI = 0.01–0.83) Assessments of patient health, the risk of deterioration, and their ability to work predicted sick leave decisions. Specialists in general medicine grant significantly fewer sick leaves than non-specialists. Conclusion Sick-leave decisions made by GPs in the three countries were relatively similar. However, Swedish GPs were more reluctant to grant sick leave for patients with “psychological” diagnoses. Assessments regarding health-related factors were more important than diagnoses in sick-leave decisions. Specialist training may be of importance for sick-leave decisions. PMID:24164371

The effect of occupational and workplace gender composition on sickness absence.

Laaksonen, Mikko; Martikainen, Pekka; Rahkonen, Ossi; Lahelma, Eero

2012-02-01

To examine whether gender composition of the occupation or the workplace is associated with sickness absence, whether the gender composition accounts for the observed female excess in sickness absence, and whether gender composition explains variation in sickness absence rates between occupations and workplaces. Random effects models conducted among Helsinki employees (N = 36,395). Women and men working in women-dominated occupations and workplaces had more short-term (1 to 3 days') sickness absence. Gender composition of the occupation and the workplace partly explained gender differences in short-term but not in intermediate (4 to 14 days') and long-term (>2 weeks') absence. Gender composition also explained variation in short-term sickness absence among occupations and workplaces, but this was partly accounted for by social class, income, and job contract type. The results are consistent with the assumption that short-term sickness absence reflects cultures and norms shaping sickness absence behavior.

Workplace stressors, such as bullying, are strongly related to subsequent long-term sickness absence, but little is known of the possible physiological mechanisms linking workplace stressors and sickness absence. The primary aim of this study was to investigate to what extent cortisol levels were associated with subsequent sickness absence and if cortisol mediated the association between workplace bullying and sickness absence. We additionally investigated possible bidirectional associations between bullying, cortisol, and long-term sickness absence. Participants came from two Danish cohort studies, the "Psychosocial RIsk factors for Stress and MEntal disease" (PRISME) cohort and the "Workplace Bullying and Harassment" (WBH) cohort (n = 5418). Information about exposure to workplace bullying and morning and evening salivary cortisol was collected at three time points with approximately two years in between. After each data collection, all participants were followed for two years in registers, and cases with long-term sickness absence lasting 30 or more consecutive days were identified. The association between cortisol levels and subsequent sickness absence was assessed by logistic regression, while the extent to which the association between bullying and sickness absence was mediated by cortisol was quantified through natural direct and indirect effects. High evening cortisol was associated with a decreased risk of sickness absence (OR = 0.82, 95% CI = 0.68-0.99), but we did not find that high morning cortisol levels (OR = 0.98, 95% CI = 0.81-1.18) or high morning-to-evening slope (OR = 0.99, 95% CI = 0.82-1.18) were associated with subsequent sickness absence. We also tested for reverse causation and found that long-term sickness absence, but not salivary cortisol, was a strong risk factor for subsequent workplace bullying. There was no indication that cortisol mediated the association between workplace bullying and sickness absence. We found no straightforward and simple association between cortisol and long-term sickness absence. Furthermore, the association between workplace bullying and long-term sickness absence was not mediated by cortisol.

Blood flow changes and inactivity associated with motion sickness appear to exacerbate the rate of core temperature decrease during subsequent body cooling. We investigated the effects of various classes of anti-motion sickness drugs on core temperature changes. There were 12 healthy male and female subjects (20-35 yr old) who were given selected classes of anti-motion sickness drugs prior to vestibular Coriolis cross coupling induced by graded yaw rotation and periodic pitch-forward head movements in the sagittal plane. All subjects were then immersed in water at 18 degrees C for a maximum of 90 min or until their core temperature reached 35 degrees C. Double-blind randomized trials were administered, including a placebo, a non-immersion control with no drug, and six anti-motion sickness drugs: meclizine, dimenhydrinate, chlorpheniramine, promethazine + dexamphetamine, promethazine + caffeine, and scopolamine + dexamphetamine. A 7-d washout period was observed between trials. Core temperature and the severity of sickness were monitored throughout each trial. A repeated measures design was performed on the severity of sickness and core temperature changes prior to motion provocation, immediately after the motion sickness end point, and throughout the period of cold-water immersion. The most effective anti-motion sickness drugs, promethazine + dexamphetamine (with a sickness score/duration of 0.65 +/- 0.17) and scopolamine + dexamphetamine (with a sickness score/duration of 0.79 +/- 0.17), significantly attenuated the decrease in core temperature. The effect of this attenuation was lower in less effective drugs. Our results suggest that the two most effective anti-motion sickness drugs are also the most effective in attenuating the rate of core temperature decrease.

Low socioeconomic position is consistently associated with higher rates of sickness absence. We aimed to examine whether working conditions, health-related behaviours and family-related factors explain occupational class differences in medically certified sickness absence. The study included 5470 women and 1464 men employees of the City of Helsinki, surveyed in 2000-2002. These data were prospectively linked to sickness absence records until the end of 2005, providing a mean follow-up time of 3.9 years. Poisson regression was used to examine the occurrence of medically certified sickness absence episodes lasting 4 days or more. Medically certified sickness absence was roughly three times more common among manual workers than among managers and professionals in both women and men. Physical working conditions were the strongest explanatory factors for occupational class differences in sickness absence, followed by smoking and relative weight. Work arrangements and family-related factors had very small effects only. The effects of psychosocial working conditions were heterogeneous: job control narrowed occupational class differences in sickness absence while mental strain and job demands tended to widened them. Overall, the findings were quite similar in women and men. Physical working conditions provided strongest explanations for occupational class differences in sickness absence. Smoking and relative weight, which are well-known determinants of health, also explained part of the excess sickness absence in lower occupational classes. Applying tailored work arrangements to employees on sick leave, reducing physically heavy working conditions and promoting healthy behaviours provide potential routes to narrow occupational class differences in sickness absence.

To study future general and diagnoses-specific sickness absence and disability pension among young adults who were initially on long-term sick-leave due to back, neck, or shoulder diagnoses. Eleven-year prospective cohort study. All 213 adults in a Swedish municipality who, in 1985, were in the age range 25-34 years and had begun a spell of sick-leave lasting > or = 28 days with low back, neck, or shoulder diagnoses. For the time-period 1985-96, data regarding the dates and diagnoses for all periods of sick-leave, and the dates of disability pension, emigration, and death were obtained. Numbers of days of sick-leave and disability pension were analysed separately for each of the 11 years in relation to the number of days at risk for such benefits. The cohort members were on sick-leave or disability pension for 25% of all days at risk during the 11 years of follow-up. A large difference in the number of sick-leave days between the 22% of subjects who were later granted disability pension and the others was already apparent during the first 2 years. During the entire period, up to 21% of the sick-leave days for women and 24% for men entailed psychiatric diagnoses. This cohort of young adults, initially off sick for 4 weeks due to back, neck, or shoulder diagnoses, also had a high level of sickness absence in the subsequent 11 years with other diagnoses.

Sick-visit immunizations and delayed well-baby visits.

Robison, Steve G

2013-07-01

Giving recommended immunizations during sick visits for minor and acute illness such as acute otitis media has long been an American Academy of Pediatrics/Advisory Committee on Immunization Practice recommendation. An addition to the American Academy of Pediatrics policy in 2010 advised considering whether giving immunizations at the sick visit would discourage making up missed well-baby visits. This study quantifies the potential tradeoff between sick-visit immunizations and well-baby visits. This study was a retrospective cohort analysis with a case-control component of sick visits for acute otitis media that supplanted normal well-baby visits at age 2, 4, or 6 months. Infants were stratified for sick-visit immunization, no sick-visit immunization but quick makeup well-baby visits, or no sick-visit immunizations or quick makeup visits. Immunization rates and well-baby visit rates were assessed through 24 months of age. For 1060 study cases, no significant difference was detected in immunization rates or well-baby visits through 24 months of age between those with or without sick-visit immunizations. Thirty-nine percent of infants without a sick-visit shot failed to return for a quick makeup well-baby visit; this delayed group was significantly less likely to be up-to-date for immunizations (relative risk: 0.66) and had fewer well-baby visits (mean: 3.8) from 2 through 24 months of age compared with those with sick-visit shots (mean: 4.7). The substantial risk that infants will not return for a timely makeup well-baby visit after a sick visit should be included in any consideration of whether to delay immunizations.

The purpose of this investigation is to evaluate a methodology designed to accurately trace the temporal progression of motion sickness and space motion sickness symptoms. With this method, subjects continuously monitor their own motion sickness symptoms during exposure to a provocative stimulus as symptoms occur, in contrast to previous methods during which subjects report symptoms verbally at discrete time intervals. This method not only is comparable to previous methods in the type of symptoms that subjects report, but subjects report symptoms more frequently. Frequent reporting of motion sickness symptoms allows researchers to detail the waxing and waning of motion sickness symptoms for each individual. Previous research has shown that physiological responses to motion sickness stimuli are characterized by unique individual differences in response patterns. By improving our assessment of motion sickness symptoms with continuous monitoring of symptoms, the relationship between specific physiological responses and sickness levels can be more accurately determined for each individual. Results from this study show significant positive relationships between skin conductance levels and symptom levels for ten individuals; a significant positive relationship between temperature and symptom levels for 5 of 10 individuals; and both positive and negative relationships between respiration, heart rate, blood volume pulse and symptom levels. Continuous monitoring of motion sickness symptoms can be used to more accurately assess motion sickness to aid in the evaluation of countermeasures. In addition, recognition of the onset of symptoms that are strongly related to specific physiological responses could be used as cues to initiate procedures (e.g., Autogenic Feedback Training) to prevent the development of severe motion sickness symptoms.

Colla, Carrie H.; Dow, William H.; Dube, Arindrajit; Lovell, Vicky

2014-01-01

Objectives. We examined employers’ responses to San Francisco, California’s 2007 Paid Sick Leave Ordinance. Methods. We used the 2009 Bay Area Employer Health Benefits Survey to describe sick leave policy changes and the policy’s effects on firm (n = 699) operations. Results. The proportion of firms offering paid sick leave in San Francisco grew from 73% in 2006 to 91% in 2009, with large firms (99%) more likely to offer sick leave than are small firms (86%) in 2009. Most firms (57%) did not make any changes to their sick leave policy, although 17% made a major change to sick leave policy to comply with the law. Firms beginning to offer sick leave reported reductions in other benefits (39%), worse profitability (32%), and increases in prices (18%) but better employee morale (17%) and high support for the policy (71%). Many employers (58%) reported some difficulty understanding legal requirements, complying administratively, or reassigning work responsibilities. Conclusions. There was a substantial increase in paid sick leave coverage after the mandate. Employers reported some difficulties in complying with the law but supported the policy overall. PMID:24432927

Increasing accuracy in the assessment of motion sickness: A construct methodology

Stout, Cynthia S.; Cowings, Patricia S.

1993-01-01

The purpose is to introduce a new methodology that should improve the accuracy of the assessment of motion sickness. This construct methodology utilizes both subjective reports of motion sickness and objective measures of physiological correlates to assess motion sickness. Current techniques and methods used in the framework of a construct methodology are inadequate. Current assessment techniques for diagnosing motion sickness and space motion sickness are reviewed, and attention is called to the problems with the current methods. Further, principles of psychophysiology that when applied will probably resolve some of these problems are described in detail.

Sickness absence is a considerable economic and social problem. Short-term sickness absence is known to be associated with behavioural attitudes. The correlation between sickness absence and job satisfaction has been studied infrequently and with contradictory results. This study investigated the correlation between short-term sickness absence and both global and specific job satisfaction. We defined short-term sickness absence as spells of up to 42 days. A random sample of 898 Dutch workers from a variety of economic sectors and companies received a self-report questionnaire on their first day of sick leave. The questionnaire measured global and specific job satisfaction. In our regression analysis, we controlled for the confounding factors of age, gender, educational level, perceived workload, job autonomy and decision latitude. The duration of an absence spell was defined as the amount of calendar days between sick leave and return to work. Global job satisfaction did not correlate significantly with the duration of short-term sickness absence. While increasing physical job demands predicted longer absence, increasing job autonomy and educational level predicted shorter absence. Satisfaction with colleagues predicted longer duration absence. Global job satisfaction did not correlate with the duration of short-term absence spells, but specific satisfaction with colleagues was associated with longer sickness spells.

The effect of office type on sickness absence among office employees was studied prospectively in 1852 employees working in (1) cell-offices; (2) shared-room offices; (3) small, (4) medium-sized and (5) large open-plan offices; (6) flex-offices and (7) combi-offices. Sick leaves were self-reported two years later as number of (a) short and (b) long (medically certified) sick leave spells as well as (c) total number of sick leave days. Multivariate logistic regression analysis was used, with adjustment for background factors. A significant excess risk for sickness absence was found only in terms of short sick leave spells in the three open-plan offices. In the gender separate analysis, this remained for women, whereas men had a significantly increased risk in flex-offices. For long sick leave spells, a significantly higher risk was found among women in large open-plan offices and for total number of sick days among men in flex-offices. A prospective study of the office environment's effect on employees is motivated by the high rates of sick leaves in the workforce. The results indicate differences between office types, depending on the number of people sharing workspace and the opportunity to exert personal control as influenced by the features that define the office types.

To investigate whether family obligations influence the risk of sickness absence among female municipal employees in Sweden. A 1-year prospective cohort study of 1464 female municipal employees <50 years of age in Sweden in 2000 was conducted using questionnaire responses and absence data from the employers' personnel records. The relative risk of having children <16 years of age in the home, marital status, household work, financial situation, working hours and work-family conflicts for repeated sick-leave spells (>or=4 spells) and long-term sickness absence (>or=28 days) were calculated by applying Poisson regression models. Women reporting financial strain or work-family conflicts were at elevated risk for long-term sickness absence. Having children was not a risk factor for repeated sick-leave spells or long-term sickness absence among married/cohabiting women. Single women with children had a two-fold greater risk of repeated sick-leave spells than single women without children. The findings suggest that the combination of gainful employment and children does not influence the risk of repeated sick-leave spells or long-term sickness absence among married/cohabiting publicly employed women. However, this was not true for single women with children, which indicates that their circumstances are particularly strained.

Gender differences in motion sickness history and susceptibility to optokinetic rotation-induced motion sickness.

The present study investigated gender differences in motion sickness history and susceptibility to optokinetic rotation-induced motion sickness. The study included two phases. In Phase 1, 485 subjects filled out a survey of previous incidence of motion sickness. Results indicated that women reported significantly greater incidence of feeling motion sickness than did men on buses, on trains, on planes, in cars, and on amusement rides before the age of 12 yr; and on buses, on trains, on planes, in boats, on ships, in cars, on amusement rides, and on swings between the ages of 12 and 25 yr. Women also reported significantly higher incidence of being actually sick than did men on buses before the age of 12 yr and on buses, on ships, and in cars between the ages of 12 and 25 yr. In Phase 2, each of the 47 subjects viewed an optokinetic rotating-drum for 16 min. Subjects' subjective symptoms of motion sickness (SSMS) were obtained during drum rotation. The results showed that there were no significant differences on SSMS scores between men and women. Although women reported greater incidence in motion sickness history, women did not differ from men in severity of symptoms of motion sickness while viewing a rotating optokinetic drum.

Obesity is an increasing public health problem. A small number of studies have examined the relationship between obesity and sickness absence, with mixed results, particularly regarding short-term sickness absence. To determine if obesity is associated with short- and long-term sickness absence and to investigate the mechanisms that may underlie any association. Cross-sectional (n = 1489) and prospective (n = 625) analyses were conducted on staff from London Underground Ltd. All participants underwent regular clinical examinations that involved their height and weight being measured, obesity-related medical problems being diagnosed and psychiatric disorders being identified. The number of days taken for short- (<10 days in an episode) and long-term sickness absence were recorded by managers on an electronic database. There was a positive linear association between employees' body mass index (BMI) and the number of days' work missed due to sickness absence on both cross-sectional and prospective analyses (P < 0.001). Obesity was a risk factor for both short- and long-term sickness absence. Obese individuals typically took an extra 4 days sick leave every year. The majority of the increased risk for long-term sickness absence appeared to be mediated via co-morbid chronic medical conditions. The excess short-term sickness absence was not explained by obesity-related medical problems, psychiatric disorders or workplace factors. Obese employees take significantly more short- and long-term sickness absence than workers of a healthy weight. There is growing evidence to support employers becoming more involved in tackling obesity.

Sickness presenteeism: The prevalence of coming to work while ill among paediatric resident physicians in Canada.

Sickness presenteeism is defined as the act of attending one's job despite ill-health. Recently, physicians and other health care workers have become the focus of sickness presenteeism research, because presenteeism in this population can put patients at risk of infection. There are currently no data on this topic among physicians in Canada. The aim of this study was to investigate sickness presenteeism in paediatric resident physicians in Canada. We conducted an anonymous, online, cross-sectional survey study in which all paediatric residents in Canada were eligible. Outcomes of interest included prevalences of sickness presenteeism, sickness during the study period and voluntary self-appointed personal protective equipment use when engaging in sickness presenteeism. Response rate was 56.5% (N=323). During the previous 2 months, 61% (95% confidence interval [CI] 55.7 to 66.3) of respondents reported having experienced an illness and 59% (95% CI 53.7 to 64.5) of respondents had come to work sick. Of those who reported becoming ill during the study period, 97.0% (95% CI 94.6 to 99.4) reported coming to work while sick. There was no difference in prevalence when comparing across post-graduate year training levels. Extra personal protective equipment was used by 86% (95% CI 82.1 to 91.7) when engaging in sickness presenteeism. Sickness presenteeism is a common phenomenon among paediatric resident physicians. Our results should influence residents and supervising staff physicians to encourage appropriate self-care at home, rather than presenteeism.

Precarious employment is a major social determinant of health and health inequalities with effects beyond the health of workers. To investigate the association between precarious employment and sickness absence in 4 Nordic countries, Denmark, Finland, Norway, and Sweden. Logistic regression analyses were conducted separately for each country on data from 4186 respondents aged 15-65 years in Denmark, Finland, Norway, and Sweden derived from the 2010 European Working Conditions Survey. Sickness absence was based on self-reports and defined as absence of seven or more day per year. Precarious employment was operationalized as a multidimensional construct of indicators. Analyses were also conducted separately for men and women. The prevalence of sickness absence was lowest in Sweden (18%), and highest in Finland (28%). 3 precarious employment indicators were positively associated with sickness absence; the pattern being largely similar in the total sample. In the sex-disaggregated sample, 5 precarious employment indicators increased the likelihood of sickness absence; the pattern was heterogeneous, with women generally having significantly higher odds of sickness absence than men. "Low household income" and "sickness presenteeism" were strong predictors of sickness absence among both sexes in most of the 4 studied countries. Sickness absence varied between the Nordic countries in the sex-disaggregated analyses. Precarious employment indicators predicted sickness absence in the Nordic countries. Findings emphasize the need to prioritize informed and monitored collective bargaining for all workers, increase working time flexibility, and improving work conditions.

Determinants of sick-leave duration: a tool for managers?

PubMed

Flach, Peter A; Krol, Boudien; Groothoff, Johan W

2008-09-01

To provide managers with tools to manage episodes of sick-leave of their employees, the influence of factors such as age, gender, duration of tenure, working full-time or part-time, cause and history of sick-leave, salary and education on sick-leave duration was studied. In a cross-sectional study, data derived from the 2005 sick-leave files of a Dutch university were examined. Odds ratios of the single risk factors were calculated for short spells (or=91 days) of sick-leave. Next, these factors were studied in multiple regression models. Age, gender, duration of employment, cause and history of sick-leave, salary and membership of scientific staff, studied as single factors, have a significant influence on sick-leave duration. In multiple models, this influence remains for gender, salary, age, and history and cause of sick-leave. Only in medium or long spells and regarding the risk for a long or an extended spell do the predictive values of models consisting of psychological factors, work-related factors, salary and gender become reasonable. The predictive value of the risk factors used in this study is limited, and varies with the duration of the sick-leave spell. Only the risk for an extended spell of sick-leave as compared to a medium or long spell is reasonably predicted. Factors contributing to this risk may be used as tools in decision-making.

Relationship between motion sickness, migraine and menstruation in crew members of a "round the world" yacht race.

The similarities between the symptoms reported by patients with migraine and those experienced by severely motion sick individuals raises the question of whether the two conditions involve common mechanisms. In women, attacks of migraine may follow the menstrual cycle, and anecdote suggests this may also be true of motion sickness. The aim of this study was to determine whether there was a cyclical pattern in the occurrence of migraine/headache and motion sickness among crew members of a "round the world" yacht race. The participants were asked to complete pre- and postrace questionnaires that related to their susceptibility to motion sickness and headache/migraine; additionally, the female subjects were asked for details about their menstrual cycle. During the race the subjects completed a logbook to record the occurrence of motion sickness (using a four-point scale), migraine/headache (including the type of headache), menstruation, medication consumption and duties aboard the yacht. Female sailors were found to be more prone to motion sickness than the males. Motion sickness was also found to be linked to time at sea, and subjects who suffered migraine during the race were also more susceptible to motion sickness. A distinct pattern was found in the occurrence of motion sickness and headache that related to the menstrual cycle, although motion sickness and headache did not generally occur together in most of the subjects. A cyclical pattern was not obvious for the male subjects.

(1) Determine the relationship between emotional dissonance and medically certified sickness absence among employees working with clients and (2) compare the impact of emotional dissonance on medically certified sickness absence with the impact of other psychological and social work factors. A sample of 7758 employees was recruited from 96 Norwegian organizations in the period 2004 to 2014, all working with clients. The study design was prospective with emotional dissonance measured at baseline and then linked to official registry data of medically certified sickness absence for the year following the survey assessment. Quantitative demands, decision demands, role clarity, role conflict, control over work intensity, and decision control were included as additional work exposures. The impact of the study variables on the presence and duration of medically certified sickness absence was investigated with a negative binomial hurdle model. In the fully adjusted model, emotional dissonance and role conflict significantly predicted the presence of medically certified sickness absence. Control over work intensity and decision control were negatively related to presence of sickness absence. Only role conflict was a risk factor for the duration of sickness absence when all factors were analysed simultaneously. Emotional dissonance is a risk factor for the presence of medically certified sickness absence in client-driven work environments. Theoretical models of sickness absence, as well as interventions aiming to prevent sickness absence in such environments, should be aware of the effect emotional dissonance may have on employees.

Motion sickness: Can it be controlled

NASA is one of the few research centers concerned with motion sickness. Since the physiology of man has been developed in the one-gravity field Earth, the changes experienced by man in space are unique, and often result in symptoms that resemble motion sickness on Earth. NASA is concerned with motion sickness because it is very uncomfortable for the astronauts. Another concern of NASA is the possibility of a motion sickness astronaut regurgitating while he or she is sealed in an airtight space suit. This could be fatal. Motivated by these reasons, NASA spent thousands of dollars in research and development for a drug or technique for combating motion sickness. Several different treatments were developed for this disorder. Three of the most effective ways of combatting motion sickness are discussed.

To describe the prevalence of, reasons given for, and factors associated with sick leave during pregnancy. Longitudinal, population-based descriptive study. Akershus University Hospital, Norway. All women scheduled to give birth at the hospital (November 2008 to April 2010). Consenting women were handed a questionnaire at the routine ultrasound check at 17 weeks of gestation. Women returning this questionnaire received a second questionnaire at 32 weeks of gestation. Multiple logistic regression analyses were performed to examine associations with somatic, psychiatric and social factors. Rates and duration of sick leave. By 32 weeks of gestation, 63.2% of the 2918 women included were on sick leave, and 75.3% had been on sick leave at some point during their pregnancy. Pelvic girdle pain and fatigue/sleep problems were the main reasons given for sick leave. Being on sick leave in all trimesters was strongly associated with hyperemesis, exercising less than weekly, chronic pain before or during pregnancy, infertility treatment (all P < 0.001); younger maternal age, conflicts in the workplace (both P < 0.01); multiparity, previous depression, insomnia and lower education (all P < 0.05). Sick leave was associated with elective caesarean section and higher infant birthweight (P < 0.01). Adjustment of the work situation was associated with 1 week shorter duration of sick leave. Most women receive sick leave during pregnancy, but sick leave might not be caused by pregnancy alone. Previous medical and psychiatric history, work conditions and socio-economic factors need to be addressed to understand sick leave during pregnancy. © 2012 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2012 RCOG.

Age, occupational class and sickness absence during pregnancy: a retrospective analysis study of the Norwegian population registry

Ariansen, Anja M S

2014-01-01

Objective Western women increasingly delay having children to advance their career, and pregnancy is considered to be riskier among older women. In Norway, this development surprisingly coincides with increased sickness absence among young pregnant women, rather than their older counterparts. This paper tests the hypothesis that young pregnant women have a higher number of sick days because this age group includes a higher proportion of working class women, who are more prone to sickness absence. Design A zero-inflated Poisson regression was conducted on the Norwegian population registry. Participants All pregnant employees giving birth in 2004–2008 were included in the study. A total number of 216 541 pregnancies were observed among 180 483 women. Outcome measure Number of sick days. Results Although the association between age and number of sick days was U-shaped, pregnant women in their early 20s had a higher number of sick days than those in their mid-40s. This was particularly the case for pregnant women with previous births. In this group, 20-year-olds had 12.6 more sick days than 45-year-olds; this age difference was reduced to 6.3 after control for class. Among women undergoing their first pregnancy, 20-year-olds initially had 1.2 more sick days than 45-year-olds, but control for class altered this age difference. After control for class, 45-year-old first-time pregnant women had 2.9 more sick days than 20-year-olds with corresponding characteristics. Conclusions The negative association between age and sickness absence was partly due to younger age groups including more working class women, who were more prone to sickness absence. Young pregnant women's needs for job adjustments should not be underestimated. PMID:24793246

To analyze the duration of non-work-related sick leave due to anxiety disorders and to identify demographic, occupational and clinical variables that may contribute to its prediction. We performed a prospective cohort study of 1,161 workers with an episode of non-work-related sick leave due to an anxiety disorder, belonging to the insured population of a mutual insurance company. We assessed the duration of non-work-related sick leave episodes and the main potentially related demographic, occupational and clinical variables. All non-work-related sick leave processes were followed-up until discharge. Cox regression analyses were conducted to establish the predictors of non-work-related sick leave duration. The median duration of non-work-related sick leave due to anxiety disorders was 83 days. In a multivariate analysis, the following factors were identified as being significantly associated with increases in the duration of sick leave (p <0.05): age of over 35 years, lower educational level (primary school studies, secondary school studies or high-school diploma vs. university degree), and the existence of comorbidity and unemployment occurring during the sick leave. In contrast, being separated or divorced was associated with an earlier return to work (p <0.05). Anxiety disorders are associated with long periods of non-work-related sick leave compared with other disorders and standard time duration. Demographic, occupational and clinical variables collected at the initial assessment of the sick leave episode would help to identify groups with an increased risk of prolonged sick leave, requiring strategies to facilitate return to work.

The cat is proposed as a model for the study of motion and space sickness. Development of a scale for rating the motion sickness severity in the cat is described. The scale is used to evaluate an antimotion sickness drug, d-amphetamine plus scopolamine, and to determine whether it is possible to predict sickness susceptibility during parabolic flight, including zero-G maneuvers, from scores obtained during ground based trials.

Sickness absence patterns and trends in the health care sector: 5-year monitoring of female municipal employees in the health and care sectors in Norway and Denmark

PubMed Central

2014-01-01

Background Sickness absence is a growing public health problem in Norway and Denmark, with the highest absence rates being registered in Norway. We compared time trends in sickness absence patterns of municipal employees in the health and care sectors in Norway and Denmark. Methods Data from 2004 to 2008 were extracted from the personnel registers of the municipalities of Kristiansand, Norway, and Aarhus, Denmark, for 3,181 and 8,545 female employees, respectively. Age-specific comparative statistics on sickness absence rates (number of calendar days of sickness absence/possible working days) and number of sick leave episodes were calculated for each year of the study period. Results There was an overall increasing trend in sickness absence rates in Denmark (P = 0.002), where rates were highest in the 20–29- (P = 0.01) and 50–59-year-old age groups (P = 0.03). Sickness absence rates in Norway were stable, except for an increase in the 20–29-year-old age group (P = 0.004). In both Norway and Denmark, the mean number of sick leave episodes increased (P <0.0001 and P <0.0001, respectively) in all age groups except for the 30–39- and 60–67-year-old age groups. The proportion of employees without sickness absence was higher in Norway than in Denmark. Both short-term and long-term absence increased in Denmark (P = 0.003 and P <0.0001, respectively), while in Norway, only short-term absence increased (P = 0.09). Conclusions We found an overall increase in sickness absence rates in Denmark, while the largest overall increase in sick leave episodes was found in Norway. In both countries, the largest increases were observed among young employees. The results indicate that the two countries are converging in regard to sickness absence measured as rates and episodes.

Zero-G parabolic flight reproduces the weightlessness of space for short periods. However, motion sickness may affect some fliers. The aim was to assess the extent of this problem and to find possible predictors and modifying factors. Airbus zero-G flights consist of 31 parabolas performed in blocks. Each parabola consisted of 20 s of 0 g sandwiched by 20 s of hypergravity of 1.5-1.8 g. The survey covered N = 246 person-flights (193 men, 53 women), ages (M ± SD) 36.0 ± 11.3 yr. An anonymous questionnaire included motion sickness rating (1 = OK to 6 = vomiting), Motion Sickness Susceptibility Questionnaire (MSSQ), antimotion sickness medication, prior zero-G experience, anxiety level, and other characteristics. Participants had lower MSSQ percentile scores (27.4 ± 28.0) than the population norm of 50. Motion sickness was experienced by 33% and 12% vomited. Less motion sickness was predicted by older age, greater prior zero-G flight experience, medication with scopolamine, lower MSSQ scores, but not gender or anxiety. Sickness ratings in fliers pretreated with scopolamine (1.81 ± 1.58) were lower than for nonmedicated fliers (2.93 ± 2.16), and incidence of vomiting in fliers using scopolamine treatment was reduced by half to a third. Possible confounding factors including age, sex, flight experience, and MSSQ could not account for this. Motion sickness affected one-third of zero-G fliers despite being intrinsically less motion sickness susceptible compared to the general population. Susceptible individuals probably try to avoid such a provocative environment. Risk factors for motion sickness included younger age and higher MSSQ scores. Protective factors included prior zero-G flight experience (habituation) and antimotion sickness medication.Golding JF, Paillard AC, Normand H, Besnard S, Denise P.

The scientific evidence on the causes for sick leave attributed to back and neck disorders was reviewed. Categories were established for acute, recurring, and chronic problems based on the duration of the sick leave period. Forty-eight articles were found to be relevant, whereof two were of high quality and 26 were of medium or low quality. Quality was assessed exclusively in relation to the aim of this systematic review. The results reveal limited published research on causes for sick leave from back and neck disorders. The generalisability of the findings is also limited since most of the subjects were men and employees in manufacturing industries. Women, white-collar workers, employees in the public sector (care, social services, schools, etc) were underrepresented in the studies. Hence, these groups and areas should be studied further to verify conclusions and enhance knowledge about the causes for sick leave from back and neck disorders. The following factors were found to have consistent, but limited, support as regards their influence on the risk for sick leave due to back and neck disorders: (a) heavy physical workload, bent or twisted working position, and low work satisfaction increases the risk for short-term and long-term sick leave; (b) specific back diagnoses and previous sick leave due to back disorders increases the risk for short-term and long-term sick leave; (c) female gender, smoking, exposure to vibration, and deficient social support were not found to significantly increase the risk for short-term and long-term sick leave; (d) self-reported pain and functional impairments were associated with a high risk for long-term sick leave; (e) longer employment periods reduced the risk for short-term sick leave; (f) perceived demands at work did not influence short-term sick leave; (g) female gender and higher age increases the risk for disability pension.

To investigate whether burnout predicts sickness absence days and sickness absence spells in human service workers. A total of 824 participants from an ongoing prospective study in different human service sector organisations were eligible for the three year follow up analysis. Burnout was measured with the work related burnout scale of the Copenhagen Burnout Inventory. Sickness absence was measured with self-reported number of days and spells during the last 12 months before the baseline and the follow up survey. A Poisson regression model with a scale parameter was used to account for over dispersion. A linear regression model was used for analysing changes in burnout and absence between baseline and follow up. Burnout was prospectively associated with both sickness absence days and sickness absence spells per year. Differences in sickness absence days varied from a mean of 5.4 days per year in the lowest quartile of the work related burnout scale to a mean of 13.6 in the highest quartile. An increase of one standard deviation on the work related burnout scale predicted an increase of 21% in sickness absence days per year (rate ratio 1.21, 95% CI 1.11 to 1.32) after adjusting for gender, age, organisation, socioeconomic status, lifestyle factors, family status, having children under 7 years of age, and prevalence of diseases. Regarding sickness absence spells, an increase of one standard deviation on the work related burnout scale predicted an increase of 9% per year (rate ratio 1.09, 95% CI 1.02 to 1.17). Changes in burnout level from baseline to follow up were positively associated with changes in sickness absence days (estimate 1.94 days/year, SE 0.63) and sickness absence spell (estimate 0.34 spells/year, SE 0.08). The findings indicate that burnout predicts sickness absence. Reducing burnout is likely to reduce sickness absence.

An appraisal of the value of vitamin B 12 in the prevention of motion sickness

NASA Astrophysics Data System (ADS)

Kohl, Randall L.; Lacey, Carol L.; Homick, Jerry L.

Unpublished reports have suggested that hydroxycobalamin (B 12, i.m.) prevents motion sickness. Some biomedical evidence supports this contention in that B 12 influences the metabolism of histidine and choline; dietary precursors to neurotransmitters with established roles in motion sickness. Susceptibility to motion sickness was evaluated after B 12 (1000 μg, i.m.). Subjects initially completed vestibular function and motion sickness susceptibility tests to establish normal vestibular function. The experimental motion stressor was a modified coriolis sickness susceptibility test. Subjects executed standardized head movements at successively higher RPM until a malaise III endpoint was reached. Following two baseline tests with this motion stressor, subjects received a B 12 injection, a second injection two weeks later, and a final motion sickness test three weeks later. No significant differences in susceptibility were noted after B 12. Hematological parameters revealed no B 12 deficiency before injection. The possibility that patients with B 12 deficiencies are more susceptible to motion sickness cannot be ruled out.

The U.S. Office of Personnel Management is issuing final regulations on the use of sick leave and advanced sick leave for serious communicable diseases, including pandemic influenza when appropriate. We are also permitting employees to substitute up to 26 weeks of accrued or accumulated sick leave for unpaid Family and Medical Leave Act (FMLA) leave to care for a seriously injured or ill covered servicemember, as authorized under the National Defense Authorization Act for Fiscal Year 2008, including up to 30 days of advanced sick leave for this purpose. Finally, we are reorganizing the existing sick leave regulations to enhance reader understanding and administration of the program.

Self-Motion Perception and Motion Sickness

NASA Technical Reports Server (NTRS)

Fox, Robert A.

1991-01-01

Motion sickness typically is considered a bothersome artifact of exposure to passive motion in vehicles of conveyance. This condition seldom has significant impact on the health of individuals because it is of brief duration, it usually can be prevented by simply avoiding the eliciting condition and, when the conditions that produce it are unavoidable, sickness dissipates with continued exposure. The studies conducted examined several aspects of motion sickness in animal models. A principle objective of these studies was to investigate the neuroanatomy that is important in motion sickness with the objectives of examining both the utility of putative models and defining neural mechanisms that are important in motion sickness.

2013-02-01

The aim of this study was to analyse the impact of the effort-reward imbalance and learning motivation on sickness absence duration and sickness absence frequency among beginning teachers in Flanders (Belgium). A total of 603 teachers, who recently graduated, participated in this study. Effort-reward imbalance and learning motivation were assessed by means of self-administered questionnaires. Prospective data of registered sickness absence during 12 months follow-up were collected. Multivariate logistic regression analyses were performed. An imbalance between high efforts and low rewards (extrinsic hypothesis) was associated with longer sickness absence duration and more frequent absences. A low level of learning motivation (intrinsic hypothesis) was not associated with longer sickness absence duration but was significantly positively associated with sickness absence frequency. No significant results were obtained for the interaction hypothesis between imbalance and learning motivation. Further research is needed to deepen our understanding of the impact of psychosocial work conditions and personal resources on both sickness absence duration and frequency. Specifically, attention could be given to optimizing or reducing efforts spent at work, increasing rewards and stimulating learning motivation to influence sickness absence.

The postural instability theory of motion sickness predicts that subjective symptoms of motion sickness will be preceded by unstable control of posture. In previous studies, this prediction has been confirmed with measures of the spatial magnitude and the temporal dynamics of postural activity. In the present study, we examine whether precursors of visually induced motion sickness might exist in postural time-to-contact, a measure of postural activity that is related to the risk of falling. Standing participants were exposed to oscillating visual motion stimuli in a standard laboratory protocol. Both before and during exposure to visual motion stimuli, we monitored the kinematics of the body's center of pressure. We predicted that postural activity would differ between participants who reported motion sickness and those who did not, and that these differences would exist before participants experienced subjective symptoms of motion sickness. During exposure to visual motion stimuli, the multifractality of sway differed between the Well and Sick groups. Postural time-to-contact differed between the Well and Sick groups during exposure to visual motion stimuli, but also before exposure to any motion stimuli. The results provide a qualitatively new type of support for the postural instability theory of motion sickness.

Approximately 3% of employees are absent from work due to illness daily in Europe, while in some countries sickness absence exceeds 20 days per year. Based on a limited body of reliable studies, Greek employees in the private sector seem to be absent far less frequently (<5 days/year) compared to most of the industrialized world. The aim of this study was to estimate the levels of sickness absence in the private sector in Greece, using shipyard and national insurance data. Detailed data on absenteeism of employees in a large shipyard company during the period 1999-2006 were utilized. National data on compensated days due to sickness absence concerning all employees (around 2 million) insured by the Social Insurance Institute (IKA, the largest insurance scheme in Greece) were retrieved from the Institute's annual statistical reports for the period 1987-2006. Sick-leave days per employee and sick-leave rate (%) were calculated, among other indicators. In the shipyard cohort, the employment time loss due to sick leave was 1%. The mean number of sick-leave days per employee in shipyards ranged between 4.6 and 8.7 and sick-leave rate (sickness absenteeism rate) varied among 2% and 3.7%. The corresponding indicators for IKA were estimated between 5 and 6.3 sick-leave days per insured employee (median 5.8), and 2.14-2.72% (median 2.49%), respectively. Short sick-leave spells (<4 days) may account at least for the 25% of the total number of sick-leave days, currently not recorded in national statistics. The level of sickness absence in the private sector in Greece was found to be higher than the suggested by previous reports and international comparative studies, but still remains one of the lowest in the industrialized world. In the 20-years national data, the results also showed a 7-year wave in sickness absence indexes (a decrease during the period 1991-1997 and an increase in 1998-2004) combined with a small yet significant decline as a general trend. These observations deserve detailed monitoring and could only partly be attributed to the compensation and unemployment rates in Greece so other possible reasons should be explored.

Assessing fitness for work: GPs judgment making.

Foley, Michelle; Thorley, Kevan; Van Hout, Marie-Claire

2013-12-01

The complexity of a fitness for work consultation is well documented. General practitioners (GPs) find that such consultations often create conflict and they feel ill-prepared for the task. We aimed to examine the consultation process in the fitness for work consultation and to report on the response of GPs to two hypothetical consultations of work related sickness absence, one of a psychological and one of a physical nature. Three areas of the consultation were examined; social/family circumstances, workplace history and information required assessing the severity of the condition. We used a randomized design using an online questionnaire completed by 62 GPs located in the Republic of Ireland. Analysis was conducted in NVivo 8 qualitative software using thematic and content analysis techniques. GPs may be expected to collect and consider information relating to social, domestic, financial, lifestyle and workplace factors, including workload, job satisfaction, job strain, work ethic, inter staff relationships and employee support mechanisms. The mode of presentation may trigger specific information seeking in the consultation. GPs may evaluate fitness for work in a variety of ways depending on medical and non-medical factors. Further research should further examine the factors that may influence the GPs decision to prescribe sickness leave.

Adaptive Changes In Postural Equilibrium And Motion Sickness Following Repeated Exposures To Virtual Environments

NASA Technical Reports Server (NTRS)

Harm, D. L.; Taylor, L. C.

2006-01-01

Virtual environments offer unique training opportunities, particularly for training astronauts and preadapting them to the novel sensory conditions of microgravity. Two unresolved human factors issues in virtual reality (VR) systems are: 1) potential "cybersickness", and 2) maladaptive sensorimotor performance following exposure to VR systems. Interestingly, these aftereffects are often quite similar to adaptive sensorimotor responses observed in astronauts during and/or following space flight. Changes in the environmental sensory stimulus conditions and the way we interact with the new stimuli may result in motion sickness, and perceptual, spatial orientation and sensorimotor disturbances. Initial interpretation of novel sensory information may be inappropriate and result in perceptual errors. Active exploratory behavior in a new environment, with resulting feedback and the formation of new associations between sensory inputs and response outputs, promotes appropriate perception and motor control in the new environment. Thus, people adapt to consistent, sustained alterations of sensory input such as those produced by microgravity, unilateral labyrinthectomy and experimentally produced stimulus rearrangements. Adaptation is revealed by aftereffects including perceptual disturbances and sensorimotor control disturbances. The purpose of the current study was to compare disturbances in postural control produced by dome and head-mounted virtual environment displays, and to examine the effects of exposure duration, and repeated exposures to VR systems. Forty-one subjects (21 men, 20 women) participated in the study with an age range of 21-49 years old. One training session was completed in order to achieve stable performance on the posture and VR tasks before participating in the experimental sessions. Three experimental sessions were performed each separated by one day. The subjects performed a navigation and pick and place task in either a dome or head-mounted display (HMD) VR system for either 30 or 60 min. The environment was a square room with 15 pedestals on two opposite walls. The objects appeared on one set of pedestals and the subject s objective was to move the objects to the other set of pedestals. After the subject picked up an object, a pathway appeared and they were required to follow the pathway to the other side of the room. The subject was instructed to perform the task as quickly and accurately as possible, avoiding hitting walls and other any obstacles and placing the object on the center of the pedestal. Postural equilibrium was measured (using the Equitest CDP balance system, Neurocom, International) before, immediately after, and at 1 hr, 2 hr, 4 hr and 6 hr following exposure to VR. Postural equilibrium was measured during quiet stance with eyes open, eyes closed and vision and/or ankle proprioceptive inputs selectively altered by servo-controlling the visual surround and/or support surface to the subject s center of mass sway. Posture data was normalized using a log transformation and motion sickness data were normalized using the square root. In general, we found that exposure to VR resulted in decrements in postural stability. The largest decrements were observed in the tests performed immediately following exposure to VR and showed a fairly rapid recovery across the remaining test sessions. In addition, subjects generally showed improvement across days. We found significant main effects for day and time for the composite equilibrium score and for sensory organization tests (SOT) 1, 2 and 6. Significant main effects were observed for day for SOT 3 and 5. Although we found no significant main effects for gender (when center of gravity was used as a covariate), we did observe significant gender X time interaction effects for composite equilibrium and for SOT 1, 3, 4 and 5. Women appeared to show larger decrements in postural stability immediately after exposure to VR than men, but recover more quickly than n. Finally, we found no significant main effects for type of VR device or for exposure duration, however, these factors did interact with other factors during some of the SOTs. Subjects exhibited rapid recovery of motion sickness symptoms across time following exposure to VR and significantly less severe symptoms across days. We did not observe main effects for gender, type of device or duration of exposure. Individuals recovered from the detrimental effects of exposure to virtual reality on postural control and motion sickness within one hour. Sickness severity and initial decrements in postural equilibrium decreases over days, which suggests that subjects become dual-adapted over time. These findings provide some direction for developing training schedules for VR users that facilitate adaptation, and support the idea that preflight training of astronauts may serve as useful countermeasure for the sensorimotor effects of space flight.

We describe a system for the automated certification of safety properties of NASA software. The system uses Hoare-style program verification technology to generate proof obligations which are then processed by an automated first-order theorem prover (ATP). For full automation, however, the obligations must be aggressively preprocessed and simplified We describe the unique requirements this places on the ATP and demonstrate how the individual simplification stages, which are implemented by rewriting, influence the ability of the ATP to solve the proof tasks. Experiments on more than 25,000 tasks were carried out using Vampire, Spass, and e-setheo.

Motion sickness symptoms, stimuli, and drug therapy are discussed. Autogenic feedback training (AFT) methods of preventing motion sickness are explained. Research with AFT indicates that participants who had AFT could withstand longer periods of Coriolis acceleration, participants with high or low susceptibility to motion sickness could control their symptoms with AFT, AFT for Coriolis acceleration is transferable to other motion sickness stimuli, and most people can learn AFT, though with varying rates of learning.

Motion sickness can be a limiting factor for sea and air missions. We report the experience of a Pararescue (PJ) team on a Pacific Ocean rescue mission in which motion sickness was prevalent. Cinnarizine, an antagonist of H1-histamine receptors, was used to treat affected PJs. We also report findings of a survey of PJs regarding motion sickness. A family of four on a disabled sailboat 900 miles off the coast of Mexico sent out a distress call because their 1-year-old daughter became severely ill with fever and diarrhea. Four PJs were deployed on a C-130, performed a free-fall parachute insertion into the ocean, and boarded the sailboat. All four PJs experienced onset of motion sickness at some point during the early part of the mission and symptoms persisted through the first 24 hours. Three PJs experienced ongoing nausea, vomiting, dizziness, and sensory imbalances. The captain of the sailboat offered the three sick PJs approximately 18mg of cinnarizine two or three times a day with relief of symptoms and improvement on operational effectiveness. A new, anonymous, voluntary survey of Air National Guard PJs and combat rescue officers revealed that 78.4% of Operators have experienced motion sickness at sea. We discuss the current theories on motion sickness, the effect of motion sickness on operational effectiveness, and research on treatment of motion sickness, including the medication cinnarizine. 2015.

Objective With pressure for older people to remain in work, research is needed on how people aged over 65 years fare in the labour market. However, few studies have focused on sick leave among older workers, especially those over the standard retirement age. This study investigated changes in sick-leave patterns among people aged over 65 years still in work. Methods All individuals in Sweden who turned 65 years old in 2000 or 2005 were followed from 1995 to 2010. The mean number of sick-leave days per year was measured for those who remained in paid work past the age of 65 years. Results Those over 65 years still working had fewer sick-leave days before the age of 65 years than those who retired. They also had fewer sick-leave days after 65 years than before. There were fewer socioeconomic differences after 65 years than before, but these differences were greater for workers over 65 years in the 2005 cohort. Conclusions Although there were more people over 65 years in paid work in 2005, sick-leave days and socioeconomic differences in sick leave were lower in this age group. Sick-leave days and socioeconomic differences in sick leave were greater in the 2005 cohort.

A study was undertaken to investigate knowledge, attitudes and practices about sleeping sickness (human African trypanosomiasis) among communities living in and around Serengeti National Park (SENAPA). Structured questionnaires were administered to a total of 1490 consenting participants. Of the respondents, 924 (62%) knew sleeping sickness, and 807 (87.3%) knew the right place to seek healthcare. Of 924 who knew sleeping sickness, 386 (42%) said the disease was present in the areas they live. Most respondents (85.4%) knew that sleeping sickness infections were acquired in the bush and forest. The most common (69.3%) sources of information about sleeping sickness were relatives and friends. Symptoms of sleeping sickness mentioned included abnormal sleep (45.2%), fever (35.3%), body malaise (14.5%), headache (7.6%) and lymph node enlargement (6.1%). Of 1490 people interviewed 90.4% knew tsetse flies and 89.8% had been bitten by tsetse flies. The majority (86.6%) of the respondents knew that sleeping sickness is transmitted through a tsetse bite. Activities that exposed people to tsetse bites included working in tsetse infested bushes/forests, grazing livestock in tsetse infested areas and hunting game animals. In conclusion, communities living in and around SENAPA were knowledgeable about tsetse and sleeping sickness. The communities can thus understand and support community based tsetse and sleeping sickness control programmes to ensure success.

To assess the influence of loss control management programs applied in an oil and gas company to sickness absence trends. After the implementation of loss control management programs in 1990, sickness absence records in 1991, 1992 and 1993 were studied. International Safety Rating System (ISRS) management elements were audited each year. Absence parameter used were sickness frequency, mean sickness days examined by employee group age, length of service, work schedule and work location. Although frequency of sickness absences remain unchanged, there was a marked decrease of mean days per absence for certain worker groups. The effects were true among agemore » group 40-49 years, service group 15-19 years, service group 20-24 years and office workers.

The identification of job opportunities for severely disabled sick-listed employees

PubMed Central

2012-01-01

Background Work disability is a major problem for both the worker and society. To explore the work opportunities in regular jobs of persons low in functional abilities, we tried to identify occupations low in task demands. Because of the variety of functional abilities and of the corresponding work demands, the disabled persons need to be classified by type of disability in a limited number of subgroups. Within each subgroup, occupations judged suitable for the most seriously disabled will be selected as having a very low level of the corresponding task demands. These occupations can be applied as reference occupations to assess the presence or absence of work capacity of sick-listed employees in regular jobs, and as job opportunities for people with a specific type of functional disability. Methods Registered data from 50,931 disability assessments within the Dutch social security system were used in a second order factor analysis to identify types of disabilities in claimants for a disability pension. Threshold values were chosen to classify claimants according to the severity of the disability. In the disability assessment procedure, a labour expert needs to select jobs with task demands not exceeding the functional abilities of the claimant. For each type of disability, the accessible jobs for the subgroup of the most severely disabled claimants were identified as lowest in the corresponding demand. Results The factor analysis resulted in four types of disabilities: general physical ability; autonomy; psychological ability; and manual skills. For each of these types of disablement, a set of four to six occupations low in task demands were selected for the subgroup of most severely disabled claimants. Because of an overlap of the sets of occupations, 13 occupations were selected in total. The percentage of claimants with at least one of the occupations of the corresponding set (the coverage), ranged from 84% to 93%. An alternative selection of six occupations for all subgroups with even less overlap had a coverage ranging from 84% to 89% per subgroup. Conclusion This study resulted in two proposals for a set of reference occupations. Further research will be needed to compare the results of the new method of disability assessment to the results of the method presently used in practice. PMID:22394686

[Greenhouse gardeners and sickness absence. A questionnaire study among greenhouse gardeners in Aarhus region].

PubMed

Pallesen, Ellen; Nielsen, Claus Vinther; Drews, Birgit Mammen

2007-02-26

The aim of the study was to examine sickness absence and risk factors for sickness absence in a population of greenhouse gardeners in the county of Arhus. The study was cross sectional and based on data from questionnaires sent to all employees and greenhouse gardens in the county. Greenhouse gardeners had an average of four days of sickness absence a year. Self-rated health was poorer than average of the Danish population in general. Female gender, age below 40 years, troublesome relationships to family and friends, "poor" physical working environment and job insecurity were all predictors for increased risk of sickness absence lasting more than two weeks a year. Sickness absence was low compared to the average of the Danish labour market. Considering poorer self-rated health and frequent occurrence of some of the above-mentioned predictors for increased risk of sickness absence--female gender, age below 40 years and for women, high exposure to "poor" physical working environment--an average sickness absence of only four days was a puzzle. The data from the study were not sufficient to explain this paradox. It might be due to compensating factors at work or at a personal level. It might be due to information bias, as sickness absence could be underestimated, but agreement between reported sickness absence from employees and greenhouse gardens diminished that probability. It might have been a consequence of selection bias, the "healthy workers'" effect. Employees with considerable sickness absence might have been dismissed for long-term absence or might have quit the job because they were not able to cope with it.

2004-01-01

The authors sought to describe risk indicators of long-term sick leave during pregnancy among hospital employees. A register-based study was undertaken of 4,852 female hospital employees aged 20-45 years from the second largest hospital in Denmark during 1995-99 based on job titles, working time, sick leave, and births combined with a survey among a total of 773 women who had been pregnant during their employment (response rate 85%). Altogether 236 (31%) were on sick leave for at least 10% of their scheduled work time during their latest pregnancy and 169 (22%) had been absent at least 20% of the time. The pregnant women had an average sickness absence of 6.1 days per month, non-pregnant women 0.95 days per month. Sick leave was more frequent in late than in early gestation. Women employed as nursing aides or hospital orderlies, launderers, and nurses had more sick leave days than other hospital employees. Part-time work, previous sickness absence not related to pregnancy, and previous chronic back pain were risk factors for long-term sick leave as were much walking or standing, long working days, high work level, little practical support from supervisors and colleagues, low job control, much lifting and night or shift work. Sick leave was unrelated to family size, support from the family and number of working years. Long-term sick leave during pregnancy was frequent and to some extent predictable. Efforts should be made to organize work for pregnant women in a manner that optimizes their health and well-being.

Sickness presenteeism: The prevalence of coming to work while ill among paediatric resident physicians in Canada

2017-01-01

Abstract Background: Sickness presenteeism is defined as the act of attending one’s job despite ill-health. Recently, physicians and other health care workers have become the focus of sickness presenteeism research, because presenteeism in this population can put patients at risk of infection. There are currently no data on this topic among physicians in Canada. The aim of this study was to investigate sickness presenteeism in paediatric resident physicians in Canada. Methods: We conducted an anonymous, online, cross-sectional survey study in which all paediatric residents in Canada were eligible. Outcomes of interest included prevalences of sickness presenteeism, sickness during the study period and voluntary self-appointed personal protective equipment use when engaging in sickness presenteeism. Results: Response rate was 56.5% (N=323). During the previous 2 months, 61% (95% confidence interval [CI] 55.7 to 66.3) of respondents reported having experienced an illness and 59% (95% CI 53.7 to 64.5) of respondents had come to work sick. Of those who reported becoming ill during the study period, 97.0% (95% CI 94.6 to 99.4) reported coming to work while sick. There was no difference in prevalence when comparing across post-graduate year training levels. Extra personal protective equipment was used by 86% (95% CI 82.1 to 91.7) when engaging in sickness presenteeism. Conclusion: Sickness presenteeism is a common phenomenon among paediatric resident physicians. Our results should influence residents and supervising staff physicians to encourage appropriate self-care at home, rather than presenteeism. PMID:29479187

Although adjustment disorder is frequently reported in clinical settings, scientific evidence is scarce regarding its impact on sickness absence and the variables associated with sickness absence duration. To report sickness absence duration and to identify predictors of long-term sickness absence in patients with adjustment disorder. This observational, prospective study included subjects with non-work-related sickness absence (>15 days) after a diagnosis of adjustment disorder. A stepwise logistic regression analysis was conducted to identify the best predictors of long-term sickness absence (≥ 6 months). There were 1182 subjects in the final analysis. The median duration of sickness absence due to adjustment disorder was 91 days. Twenty-two per cent of the subjects reported long-term sickness absence. After multivariate analysis, comorbidity (OR = 2.23, 95% CI 1.43-3.49), age (25-34 years old versus <25 years old: OR = 2.78, 95% CI 1.27-6.07; 35-44 years old versus <25 years old: OR = 3.70, 95% CI 1.71-7.99; 45-54 years old versus <25 years old: OR = 3.58, 95% CI 1.60-8.02; ≥ 55 years old versus <25 years old: OR = 6.35, 95% CI 2.64-15.31) and occupational level (blue collar versus white collar: OR = 1.52, 95% CI 1.10-2.09) remained significantly associated with long-term sickness absence. Comorbidity was the strongest predictor. It is possible to predict long-term sickness absence due to adjustment disorder on the basis of demographic, work-related and clinical information available during the basic assessment of the patient.

Examining paid sickness absence by shift workers.

Catano, V M; Bissonnette, A B

2014-06-01

Shift workers are at greater risk than day workers with respect to psychological and physical health, yet little research has linked shift work to increased sickness absence. To investigate the relationship between shift work and sickness absence while controlling for organizational and individual characteristics and shift work attributes that have confounded previous research. The study used archive data collected from three national surveys in Canada, each involving over 20000 employees and 6000 private-sector firms in 14 different occupational groups. The employees reported the number of paid sickness absence days in the past 12 months. Data were analysed using both chi-squared statistics and hierarchical regressions. Contrary to previous research, shift workers took less paid sickness absence than day workers. There were no differences in the length of the sickness absence between both groups or in sickness absence taken by female and male workers whether working days or shifts. Only job tenure, the presence of a union in the workplace and working rotating shifts predicted sickness absence in shift workers. The results were consistent across all three samples. In general, shift work does not seem to be linked to increased sickness absence. However, such associations may be true for specific industries. Male and female workers did not differ in the amount of sickness absence taken. Rotating shifts, regardless of industry, predicted sickness absence among shift workers. Consideration should be given to implementing scheduled time off between shift changes. © The Author 2014. Published by Oxford University Press on behalf of the Society of Occupational Medicine.

Approaches for predicting long-term sickness absence. Re: Schouten et al. "Screening manual and office workers for risk of long-term sickness absence: cut-off points for the Work Ability Index".

PubMed

van Amelsvoort, Ludovic Gpm; Jansen, Nicole W H; Kant, I Jmert

2015-05-01

We read with much interest the article of Schouten et al (1) on identifying workers with a high risk for future long-term sickness absence using the Work Ability Index (WAI). The ability to identify high-risk workers might facilitate targeted interventions for such workers and, consequently, can reduce sickness absence levels and improve workers' health. Earlier studies by both Tamela et al (2), Kant et al (3), and Lexis et al (4) have demonstrated that such an approach, based on the identification of high-risk workers and a subsequent intervention, can be effectively applied in practice to reduce sickness absence significantly. The reason for our letter on Schouten et al's article is twofold. First, by including workers already on sick leave in a study predicting long-term sick leave will result in an overestimation of the predictive properties of the instrument and biased predictors, especially when also the outcome of interest is included as a factor in the prediction model. Second, we object to the use of the term "screening" when subjects with the condition screened for are included in the study. Reinforced by the inclusion of sickness absence in the prediction model, including workers already on sick leave will shift the focus of the study findings towards the prediction of (re)current sickness absence and workers with a below-average return-to-work rate, rather than the identification of workers at high risk for the onset of future long-term sickness absence. The possibilities for prevention will shift from pure secondary prevention to a mix of secondary and tertiary prevention. As a consequence, the predictors of the model presented in the Schouten et al article can be used as a basis for tailoring neither preventive measures nor interventions. Moreover, including the outcome (sickness absence) as a predictor in the model, especially in a mixed population including workers with and without the condition (on sick leave), will result in biased predictors and an overestimation of the predictive value. A methodological approach of related issues is provided in the works of Glymour et al (5) and Hamilton et al (6). This phenomenon is even more clearly illustrated by the predictive properties of the workability index, as described by Alavinia et al (7, page 328), which reported that "when adjusted for individual characteristics, lifestyle factors, and work characteristics, two dimensions of the WAI were significant predictors for both moderate and long durations of sickness absence: (i) the presence of sickness absence in the past 12 months prior to the medical examination and (ii) experienced limitations due to health problems." So, when applied to the study by Schouten et al (1), this means that most of the predictive value would be related to the factors "sickness absence in the past 12 months". In addition, we object to the use of the term "screening" in the Schouten et al study as it includes workers with the intended outcome (long-term sickness absence). One can identify three separate aims to study the longitudinal association between risk factors and subsequent long-term sickness absence: (i) to establish causal risk factors for long-term sickness absence, often to find clues for primary preventive strategies (beyond the scope here); (ii) to identify high-risk workers who are still at work and might benefit from an intervention before sickness absence occurs (secondary prevention); and (iii) to identify workers on sick leave who might suffer a below-average return-to-work rate or have a high risk for the recurrence of (long-term) sickness absence and might benefit from intensification or optimization of the return-to-work process (tertiary prevention). In this light, one needs to separate screening instruments from predictive instruments and reserve the term "screening" for the situation as defined by Wilson and Junger (8, page 7): "The object of screening for disease is to discover those among the apparently well who are in fact suffering from disease" (ie, situations of secondary prevention). This means that, when applying this definition on long-term sickness absence under the precondition that the individuals are still at work, screening enables the identification of high-risk individuals in the early "stages" of a "disease" that can progress into long-term sickness absence. In the case of the Schouten et al study, the population at risk, as derived from their predictive instrument, consists of workers with and without sickness absence, and as such excludes the use of the term "screening" in this case. To conclude, we have substantiated that, in addition to correct usage of the term "screening", careful selection of the study population, predictors and most importantly the aim of the predictive model are essential in the process of developing predictive instruments aimed at identifying workers at high risk of long-term sickness absence. Two fundamentally different approaches are possible. One approach aims at identifying workers on sick leave with either a below-average chance to return to work an/or a high risk for a successive episode of long-term sickness absence. From a methodological and practical point of view, such an instrument should be developed and validated among workers already on sick leave. A second approach aims at identifying workers who are still at work but at high risk for future long-term sickness absence. To develop and validate such an instrument, a study sample where workers already on sick leave are excluded is a prerequisite. Such instruments fit in a pro-active approach of preventing future sickness absence, where an early intervention can be offered to those workers with an increased risk for future sickness absence.

Monitoring cognitive function and need with the automated neuropsychological assessment metrics in Decompression Sickness (DCS) research

Nesthus, Thomas E.; Schiflett, Sammuel G.

Hypobaric decompression sickness (DCS) research presents the medical monitor with the difficult task of assessing the onset and progression of DCS largely on the basis of subjective symptoms. Even with the introduction of precordial Doppler ultrasound techniques for the detection of venous gas emboli (VGE), correct prediction of DCS can be made only about 65 percent of the time according to data from the Armstrong Laboratory's (AL's) hypobaric DCS database. An AL research protocol concerned with exercise and its effects on denitrogenation efficiency includes implementation of a performance assessment test battery to evaluate cognitive functioning during a 4-h simulated 30,000 ft (9144 m) exposure. Information gained from such a test battery may assist the medical monitor in identifying early signs of DCS and subtle neurologic dysfunction related to cases of asymptomatic, but advanced, DCS. This presentation concerns the selection and integration of a test battery and the timely graphic display of subject test results for the principal investigator and medical monitor. A subset of the Automated Neuropsychological Assessment Metrics (ANAM) developed through the Office of Military Performance Assessment Technology (OMPAT) was selected. The ANAM software provides a library of simple tests designed for precise measurement of processing efficiency in a variety of cognitive domains. For our application and time constraints, two tests requiring high levels of cognitive processing and memory were chosen along with one test requiring fine psychomotor performance. Accuracy, speed, and processing throughout variables as well as RMS error were collected. An automated mood survey provided 'state' information on six scales including anger, happiness, fear, depression, activity, and fatigue. An integrated and interactive LOTUS 1-2-3 macro was developed to import and display past and present task performance and mood-change information.

Task shifting for the delivery of pediatric antiretroviral treatment: a systematic review.

2014-04-01

Pediatric antiretroviral treatment coverage in resource-limited settings continues to lag behind adults. Task shifting is an effective approach broadly used for adults, which some countries have also adopted for children, but implementation is limited by lack of confidence and skills among nonspecialist staff. A systematic review was conducted by combining key terms for task shifting, antiretroviral therapy (ART), and children. Five databases and two conferences were searched from inception till August 01, 2013. Eight observational studies provided outcome data for 11,828 children who received ART from nonphysician providers across 10 countries in sub-Saharan Africa. The cumulative pooled proportion of deaths was 3.2% [95% confidence interval (CI): 2.0 to 4.5] at 6 months, 4.6% (95% CI: 2.1 to 7.1) at 12 months, 6.2% (95% CI: 3.7 to 8.8) at 24 months, and 5.9% (95% CI: 3.5 to 8.3) at 36 months. Mortality and loss to follow-up in task-shifting programs were comparable to those reported by programs providing doctor- or specialist-led care. Our review suggests that task shifting of ART care can result in outcomes comparable to routine physician care, and this approach should be considered as part of a strategy to scale-up pediatric treatment. Specialist care will remain important for management of sick patients and complicated cases. Further qualitative research is needed to inform optimal implementation of task shifting for pediatric patients.

MS Non-Pharmacological Countermeasure to Decrease Landing Sickness and Improve Functional Performance While Disorientad

Upon return from spaceflight, a majority of crewmembers experience motion sickness (MS) symptoms. The interactions between crewmembers' adaptation to a gravitational transition, the performance decrements resulting from MS and/or use of promethazine (PMZ), and the constraints imposed by mission task demands could significantly challenge and limit an astronaut's ability to perform functional tasks during gravitational transitions. No operational countermeasure currently exists to mitigate the risks associated with these sensorimotor disturbances. Stochastic resonance (SR) can be thought of simply as "noise benefit" or an increase in information transfer by a system when in the presence of a non-zero level of noise. We have shown that low levels of stochastic vestibular stimulation (SVS) improve balance and locomotor performance due to SR (Goel et al. 2015, Mulavara et al. 2011, 2015). Additionally, a study in a 6-hydroxydopamine (6-OHDA) hemi-lesioned rat model of Parkinson's disease demonstrated improvements in locomotor activity after low-level SVS delivery possibly due to an increase in nigral gamma-aminobutyric acid (GABA) release in a dopamine independent way (Samoudi et al. 2012). SVS specifically increased GABA release on the lesioned, but not the intact side. These results suggest that SVS can cause targeted alterations of GABA release to affect performance of functional tasks. Activation of the GABA pathway is important in modulating MS and promoting adaptability (Cohen 2008). Magnusson et al. (2000) supported this finding by showing that the administration of a GABAB agonist caused a reversal of the symptoms that is normally seen after unilateral labyrinthectomy. Thus, GABA could play a significant role in reducing MS and promoting adaptability. We have taken advantage of the SR mechanism as a modulator of neurotransmitters to develop a unique SVS countermeasure system to mitigate MS symptoms and improve functional performance after landing. Healthy subjects (n=20) participated in two test sessions, one in which they received +/-400 microA of SVS and one where they received no stimulation (0 microA); the study design was counterbalanced. Subjects began by performing a series of four functional tasks 3-5 times as baseline measurements of task performance. Then, to induce MS, subjects walked an obstacle course with up-down reversing prisms. If they completed the course before achieving our pre-determined level of MS, they were asked to read a poster while making large up-down head movements to a metronome while still wearing the reversing prism goggles. Subjects were stopped every two minutes and asked to report their MS symptoms. Using the Pensacola Scale for motion sickness, test operators evaluated the level of MS of each subject. Once a subject reached an 8 on this scale, which is equivalent to mild malaise, or 30 minutes had passed since the start of the MS induction, this protocol was stopped. Finally, immediately after MS induction, subjects were asked to complete the four functional tasks again. Although, 100% of our subjects experienced at least one MS symptom, only 55% of our subjects experienced stomach awareness to any degree. Without SVS, only 40% of subjects lasted the full 30-minute MS induction protocol, while 65% of subjects lasted the full 30 minutes with SVS, which is nearly a significant increase (p=0.056). In addition, subjects showed significant improvement from baseline when performing a tandem walk and a prone-to-stand test immediately after the MS induction protocol was stopped but the stimulation level was continued. The results are promising and future work includes comparing MS progression between PMZ and SVS directly in subjects that are provoked to a minimum of nausea. Low levels of SVS stimulation may serve as a non-pharmacological countermeasure to replace or reduce the PMZ dosage requirements and concurrently improve functional performance during transitions to new gravitational environments after spaceflight.

Preventing recurrence of severe morning sickness.

Koren, Gideon; Maltepe, Caroline

2006-12-01

A recent Motherisk article showed that initiating antinauseants even before symptoms start could prevent recurrence of severe morning sickness. In the study described, however, different physicians used different drugs. How can one be sure which drugs work? The study of 26 women who had had severe morning sickness during previous pregnancies showed that using antiemetics before symptoms of morning sickness started appeared to prevent recurrence of severe morning sickness in subsequent pregnancies. Physicians in the United States used various antinauseant drugs. Physicians in Canada administered only one drug, the combination of doxylamine-pyridoxine (Diclectin), to 12 women. Subanalysis of these 12 women revealed that pre-emptive use of doxylamine-pyridoxine significantly decreased the likelihood that severe morning sickness would recur.

To describe the types of intervention offered, to investigate the relationship between the type of intervention given, patient-reported usefulness of interventions and the effect on self-reported work ability in a cohort of sick-listed patients with musculoskeletal disorders (MSD) or mental disorders (MD). A prospective cohort study was performed including 810 newly sick-listed patients (MSD 62 % and MD 38 %). The baseline questionnaire included sociodemographic characteristics and measures of work ability. The 3-month follow-up questionnaire included measures of work ability, type of intervention received, and judgment of usefulness. Twenty-five percent received medical intervention modalities (MI) only, 45 % received a combination of medical and rehabilitative intervention modalities (CRI) and 31 % received work-related interventions combined with medical or rehabilitative intervention modalities (WI). Behavioural treatments were more common for patients with MD compared with MSD and exercise therapy were more common for patients with MSD. The most prevalent workplace interventions were adjustment of work tasks or the work environment. Among patients with MD, WI was found to be useful and improved work ability significantly more compared with only MI or CRI. For patients with MSD, no significant differences in improved work ability were found between interventions. Patients with MD who received a combination of work-related and clinical interventions reported best usefulness and best improvement in work ability. There was no difference in improvements in work ability between rehabilitation methods in the MSD group. There seems to be a gap between scientific evidence and praxis behaviour in the rehabilitation process. Unimodal rehabilitation was widely applied in the early rehabilitation process, a multimodal treatment approach was rare and only one-third received work-related interventions. It remains a challenge to understand who needs what type of intervention.

2014 Decompression Sickness/Extravehicular Activity Risks Standing Review Panel

2014-01-01

The 2014 Decompression Sickness (DCS)/Extravehicular Activity (EVA) Risks Standing Review Panel (from here on referred to as the SRP) met for a site visit in Houston, TX on November 4 - 5, 2014. The SRP reviewed the Research Plans for The Risk of Decompression Sickness and the Risk of Injury and Compromised Performance due to EVA Operations, as well as the Evidence Reports for both of these Risks. The SRP found that the NASA DCS/EVA team did an excellent job of presenting their research plans. The SRP considers it critical that NASA proceeds with the high priority tasks identified in this report (DCS1, DCS3, DCS5). The highest priority is to determine the acceptable DCS and hypoxia risk associated with the planned human exploration beyond low Earth orbit. The risk of DCS is highly dependent upon the pressure within the exploration vehicle. If slightly more hypoxia is permitted then (even with the same percentage of oxygen) the pressure within the exploration vehicle can be lowered thus further mitigating the risk of DCS. The second highest priority is to test and validate the recommended 8.2psi/34% O2 atmosphere. Development of procedures and equipment for human exploration missions are very limited until the results of this testing are completed. The SRP also suggests that DCS7 be separated into two Gaps. Gap DCS7 should deal with DCS treatment while a new Gap should be created to deal with the long-term effects of DCS. The SRP also encourages NASA to increase collaboration with other organizations and pool resources where possible. The current NASA DCS/EVA team has the extensive expertise and a wealth of knowledge in this area. The SRP suggests that increased manpower for this team would be highly productive.

Leisure-time physical activity and direct cost of short-term sickness absence among Finnish municipal employees.

We aimed to examine the direct costs of short-term (1-14 days) sickness absence and the effect of employees' physical activity on the costs. The Finnish Helsinki Health Study survey (2007) was used in the analysis (n = 3,935). Physical activity was classified into inactive, moderately active, and vigorously active. Sickness absence (3 years follow-up) and salary data were derived from the employer's registers. On average, an employee was absent 6 days a year due to short-term sickness absence, with a production loss of 2,350 EUR during the 3 years. The vigorously active had less sickness absence than those less active. The direct cost of sickness absence of a vigorously active employee was 404 EUR less than that of an inactive employee. Promoting physical activity among employees may decrease direct cost of short-term sickness absence.

To examine the associations between psychosocial working conditions and sickness absence. Data for 21,834 employed adults from the Nord-Trøndelag Health Study (HUNT) were linked to the sickness benefit register and sickness absence during 1 year after survey participation was analyzed with logistic regression. A one unit change on a 0 to 3 self-reported job demand scale was associated with a fully adjusted 24% and 25% increased odds of sickness absence in men and women, respectively. A one unit change on a 0 to 3 scale for self-reported support at work was associated with a fully adjusted 13% and 17% reduced odds of sickness absence in men and women, respectively. The results of this study indicate that demands, and to some extent support, at work might influence sickness absence-also when adjusting for a detailed categorization of occupations.

To assess the prospective associations between self-reported physical capacity and risk of long-term sickness absence among female health care workers. Female health care workers answered a questionnaire about physical capacity and were followed in a national register of sickness absence lasting for two or more consecutive weeks during 1-year follow-up. Using Cox regression hazard ratio analyses adjusted for age, smoking, body mass index, physical workload, job seniority, psychosocial work conditions, and previous sickness absence, we modeled risk estimates for sickness absence from low and medium physical capacity. Low and medium aerobic fitness, low muscle strength, low flexibility, and low overall physical capacity significantly increased the risk for sickness absence with 20% to 34% compared with health care workers with high capacity. Low physical capacity increases the risk of long-term sickness absence among female health care workers.

The association between body mass index status and sick leave and the role of emotional exhaustion-a mediation analysis among a representative sample of dutch employees.

To investigate the associations between body mass index (BMI) and sick leave, and the mediating role of emotional exhaustion. Data were collected from a large survey among Dutch employees (n = 35,022). The causal pathway approach consisting of four regression analyses was applied. In women, moderate overweight and obesity were associated with higher sick leave; in men, obesity, but not moderate overweight, was associated with higher sick leave. Obese workers were at increased risk for emotional exhaustion. Emotional exhaustion was also associated with higher sick leave rates. Adjustment for emotional exhaustion in the association between BMI and sick leave hardly changed the effect size and significance remained. The association between BMI status and sick leave can be explained partially by the presence of emotional exhaustion. Workplace health promotion initiatives should take this into account.

Motion sickness, console video games, and head-mounted displays.

2007-10-01

We evaluated the nauseogenic properties of commercial console video games (i.e., games that are sold to the public) when presented through a head-mounted display. Anecdotal reports suggest that motion sickness may occur among players of contemporary commercial console video games. Participants played standard console video games using an Xbox game system. We varied the participants' posture (standing vs. sitting) and the game (two Xbox games). Participants played for up to 50 min and were asked to discontinue if they experienced any symptoms of motion sickness. Sickness occurred in all conditions, but it was more common during standing. During seated play there were significant differences in head motion between sick and well participants before the onset of motion sickness. The results indicate that commercial console video game systems can induce motion sickness when presented via a head-mounted display and support the hypothesis that motion sickness is preceded by instability in the control of seated posture. Potential applications of this research include changes in the design of console video games and recommendations for how such systems should be used.

[Motion sickness in motion: from carsickness to cybersickness].

- Motion sickness is not a disorder, but a normal response to a non-normal situation in which movement plays a central role, such as car travel, sailing, flying, or virtual reality.- Almost anyone can suffer from motion sickness, as long as at least one of the organs of balance functions. If neither of the organs of balance functions the individual will not suffer from carsickness, seasickness, airsickness, nor from cybersickness. - 'Cybersickness' is a form of motion sickness that is stimulated by artificial moving images such as in videogames. Because we are now exposed more often and for longer periods of time to increasingly realistic artificial images, doctors will also encounter cases of motion sickness more often. - The basis for motion sickness is the vestibular system, which can be modulated by visual-vestibular conflicts, i.e. when the movements seen by the eyes are not the same as those experienced by the organs of balance.- Antihistamines can be effective against motion sickness in everyday situations such as car travel if taken before departure, but the effectiveness of medication for motion sickness is limited.

The impact of physical activity on sickness absence.

Lahti, J; Laaksonen, M; Lahelma, E; Rahkonen, O

2010-04-01

The aim of this study was to examine whether the volume and intensity of physical activity are associated with subsequent sickness absence spells of different lengths, and how much of these associations can be explained by socioeconomic position, body mass index (BMI) and physical health functioning. Baseline data were collected by questionnaire surveys in 2000-2002 among 40-60-year-old employees of Helsinki City (n=6465, 79% women). Sickness absence data were derived from the employer's registers (mean follow-up time 3.9 years). Associations of physical activity with shorter (< or =14 days) and longer (>14 days) sickness absence spells were examined, using Poisson's regression analysis. The volume of physical activity was weakly and somewhat inconsistently associated with sickness absence. However, men and women who were vigorously active systematically had reduced risk of sickness absence, whereas the same volume of moderately intensive physical activity did not reduce the risk of sickness absence. Adjusting for BMI and in particular physical health functioning attenuated these associations, after which the associations lost statistical significance. The results suggest that vigorous physical activity is associated with sickness absence and may contribute to better work ability.

Implementation of standardized time limits in sickness insurance and return-to-work: experiences of four actors.

PubMed

Ståhl, Christian; Müssener, Ulrika; Svensson, Tommy

2012-01-01

In 2008, time limits were introduced in Swedish sickness insurance, comprising a pre-defined schedule for return-to-work. The purpose of this study was to explore experienced consequences of these time limits. Sick-listed persons, physicians, insurance officials and employers were interviewed regarding the process of sick-listing, rehabilitation and return-to-work in relation to the reform. The study comprises qualitative interviews with 11 sick-listed persons, 4 insurance officials, 5 employers and 4 physicians (n = 24). Physicians, employers, and sick-listed persons described insurance officials as increasingly passive, and that responsibility for the process was placed on the sick-listed. Several ethical dilemmas were identified, where officials were forced to act against their ethical principles. Insurance officials' principle of care often clashed with the standardization of the process, that is based on principles of egalitarianism and equal treatment. The cases reported in this study suggest that a policy for activation and early return-to-work in some cases has had the opposite effect: central actors remain passive and the responsibility is placed on the sick-listed, who lacks the strength and knowledge to understand and navigate through the system. The standardized insurance system here promoted experiences of procedural injustice, for both officials and sick-listed persons.

Job satisfaction and sickness absence: a questionnaire survey.

2008-12-01

When dissatisfaction with work precedes sickness absence, screening for satisfaction levels might usefully detect workers at risk of sickness absence. To investigate whether job satisfaction was associated with subsequent sickness absence days or episodes. A sample of workers was randomly drawn from a population of employees who had an episode of absence between January and April 2003. Job satisfaction was measured using a validated single question with a Likert-type scale ranging from 1 (very dissatisfied) to 7 (very satisfied). Job satisfaction levels were linked to the number of recorded sickness absence days and episodes in 2003, distinguishing between short (1-7 days) episodes and long (>7 days) episodes. Of 898 questionnaires distributed, 518 (58%) were returned. The mean+/-standard deviation job satisfaction level was 5.1+/-1.4 and negatively related to the number of sickness absence days. Job satisfaction was also negatively related to the number of short episodes and long episodes of absence, but these associations were not significant. Job satisfaction was significantly related to total sickness absence duration. The association with the number of sickness absence episodes was weak and just below the level of statistical significance. Assessing work satisfaction levels might usefully identify those workers most likely to have the greatest sickness absence duration.

Predicting motion sickness during parabolic flight

NASA Technical Reports Server (NTRS)

Harm, Deborah L.; Schlegel, Todd T.

2002-01-01

BACKGROUND: There are large individual differences in susceptibility to motion sickness. Attempts to predict who will become motion sick have had limited success. In the present study, we examined gender differences in resting levels of salivary amylase and total protein, cardiac interbeat intervals (R-R intervals), and a sympathovagal index and evaluated their potential to correctly classify individuals into two motion sickness severity groups. METHODS: Sixteen subjects (10 men and 6 women) flew four sets of 10 parabolas aboard NASA's KC-135 aircraft. Saliva samples for amylase and total protein were collected preflight on the day of the flight and motion sickness symptoms were recorded during each parabola. Cardiovascular parameters were collected in the supine position 1-5 days before the flight. RESULTS: There were no significant gender differences in sickness severity or any of the other variables mentioned above. Discriminant analysis using salivary amylase, R-R intervals and the sympathovagal index produced a significant Wilks' lambda coefficient of 0.36, p=0.006. The analysis correctly classified 87% of the subjects into the none-mild sickness or the moderate-severe sickness group. CONCLUSIONS: The linear combination of resting levels of salivary amylase, high-frequency R-R interval levels, and a sympathovagal index may be useful in predicting motion sickness severity.

Doctor-certified sick leave differs substantially across sectors, and among health and social workers, in particular, there is an increased risk. Previous studies have shown that work environmental factors contribute to sick leave. Hence, the identification of specific organizational and psychosocial risk factors for long- term sick leave, taking into account potential confounding related to mechanical risk factors such as lifting and awkward body postures, will be of importance in the work of prevention. A randomly drawn population sample of Norwegian residents was interviewed about working conditions in 2009 (n = 12,255; response rate 60.9%). Female health and social care workers (n = 925) were followed in a national registry for subsequent sickness absence during 2010. The outcome of interest was doctor-certified sick leave of 21 days or more (long-term sick leave). Eleven work-related psychosocial and organizational factors were evaluated. In total, 186 persons (20.1%) were classified with subsequent long-term sick leave. After thoroughly adjusting for competing explanatory variables, the most consistent predictors for long-term sick leave were violence and threats of violence (OR = 1.67; 95% CI 1.14-2.45). The estimated population attributable risk for violence and threats of violence was 13%. The present study among female health and social care workers revealed a substantial relationship between self-reported violence and threats of violence and subsequent long- term sick leave.

Optometric measurements predict performance but not comfort on a virtual object placement task with a stereoscopic three-dimensional display

Twelve participants were tested on a simple virtual object precision placement task while viewing a stereoscopic three-dimensional (S3-D) display. Inclusion criteria included uncorrected or best corrected vision of 20/20 or better in each eye and stereopsis of at least 40 arc sec using the Titmus stereotest. Additionally, binocular function was assessed, including measurements of distant and near phoria (horizontal and vertical) and distant and near horizontal fusion ranges using standard optometric clinical techniques. Before each of six 30 min experimental sessions, measurements of phoria and fusion ranges were repeated using a Keystone View Telebinocular and an S3-D display, respectively. All participants completed experimental sessions in which the task required the precision placement of a virtual object in depth at the same location as a target object. Subjective discomfort was assessed using the simulator sickness questionnaire. Individual placement accuracy in S3-D trials was significantly correlated with several of the binocular screening outcomes: viewers with larger convergent fusion ranges (measured at near distance), larger total fusion ranges (convergent plus divergent ranges, measured at near distance), and/or lower (better) stereoscopic acuity thresholds were more accurate on the placement task. No screening measures were predictive of subjective discomfort, perhaps due to the low levels of discomfort induced.

Labour market trajectories following sickness absence due to self-reported all cause morbidity--a longitudinal study.

To investigate differences in return to work (RTW) and employment trajectories in individuals on sick leave for either mental health reasons or other health related reasons. This study was based on 2036 new sickness absence cases who completed a questionnaire on social characteristics, expectations for RTW and reasons for sickness absence. They were divided into two exposure groups according to their self-reported sickness absence reason: mental health reasons or other health reasons. The outcome was employment status during the following 51 weeks and was measured both as time-to-event analysis and with sequence analysis. Individuals with mental health reasons for sickness absence had a higher risk of not having returned to work (RR 0.87 (0.80;0.93)). Adjusting for gender, age, education and employment did not change the estimate, however, after adding RTW expectations to the model, the excess risk was no longer present (RR 1.01 (0.95;1.08)). In relation to the sequence analysis, individuals with mental health related absence had significantly higher odds of being in the sickness absence cluster and significantly lower odds for being in the fast RTW cluster, but when adjusting for RTW expectations, the odds were somewhat attenuated and no longer significant. Employees on sick leave due to self-reported mental health problems spent more weeks in sickness absence and temporary benefits and had a higher risk of not having returned to work within a year compared to employees on sick leave due to other health reasons. The difference could be explained by their lower RTW expectations at baseline. This emphasises the need to develop suitable and specific interventions to facilitate RTW for this group of sickness absentees.

Driving simulator sickness: Impact on driving performance, influence of blood alcohol concentration, and effect of repeated simulator exposures.

Simulator sickness is a major obstacle to the use of driving simulators for research, training and driver assessment purposes. The purpose of the present study was to investigate the possible influence of simulator sickness on driving performance measures such as standard deviation of lateral position (SDLP), and the effect of alcohol or repeated simulator exposure on the degree of simulator sickness. Twenty healthy male volunteers underwent three simulated driving trials of 1h's duration with a curvy rural road scenario, and rated their degree of simulator sickness after each trial. Subjects drove sober and with blood alcohol concentrations (BAC) of approx. 0.5g/L and 0.9g/L in a randomized order. Simulator sickness score (SSS) did not influence the primary outcome measure SDLP. Higher SSS significantly predicted lower average speed and frequency of steering wheel reversals. These effects seemed to be mitigated by alcohol. Higher BAC significantly predicted lower SSS, suggesting that alcohol inebriation alleviates simulator sickness. The negative relation between the number of previous exposures to the simulator and SSS was not statistically significant, but is consistent with habituation to the sickness-inducing effects, as shown in other studies. Overall, the results suggest no influence of simulator sickness on SDLP or several other driving performance measures. However, simulator sickness seems to cause test subjects to drive more carefully, with lower average speed and fewer steering wheel reversals, hampering the interpretation of these outcomes as measures of driving impairment and safety. BAC and repeated simulator exposures may act as confounding variables by influencing the degree of simulator sickness in experimental studies. Copyright © 2016 Elsevier Ltd. All rights reserved.

Long-term sickness absence is one of the main risk factors for permanent exit out of the labour market. Early identification of the condition is essential to facilitate return to work. The aim of this study was to analyse possible determinants of return to work and their relative impact. All 943 subjects aged 18 to 63 years, sickness certified at a Primary Health Care Centre in Sweden from 1 January until 31 August 2004, were followed up for three years. Baseline information on sex, age, sick leave diagnosis, employment status, extent of sick leave, and sickness absence during the year before baseline was obtained, as was information on all compensated days of sick leave, disability pension and death during follow-up. Slightly more than half the subjects were women, mean age was 39 years. Half of the study population returned to work within 14 days after baseline, and after three years only 15 subjects were still on sick leave. In multivariate proportional hazards regression analysis the extent of previous sick leave, age, being on part-time sick leave, and having a psychiatric, musculoskeletal, cardiovascular, nervous disease, digestive system, or injury or poisoning diagnosis decreased the return to work rate, while being employed increased it. Marital status, sex, being born in Sweden, citizenship, and annual salary had no influence. In logistic regression analyses across follow-up time these variables altogether explained 88-90% of return to work variation. Return to work was positively or negatively associated by a number of variables easily accessible in the GP's office. Track record data in the form of previous sick leave was the most influential variable.

Work-related psychosocial events as triggers of sick leave--results from a Swedish case-crossover study.

Although illness is an important cause of sick leave, it has also been suggested that non-medical risk factors may influence this association. If such factors impact on the period of decision making, they should be considered as triggers. Yet, there is no empirical support available.The aim was to investigate whether recent exposure to work-related psychosocial events can trigger the decision to report sick when ill. A case-crossover design was applied to 546 sick-leave spells, extracted from a Swedish cohort of 1430 employees with a 3-12 month follow-up of new sick-leave spells. Exposure in a case period corresponding to an induction period of one or two days was compared with exposure during control periods sampled from workdays during a two-week period prior to sick leave for the same individual. This was done according to the matched-pair interval and the usual frequency approaches. Results are presented as odds ratios (OR) with 95% confidence intervals (CI). Most sick-leave spells happened in relation to acute, minor illnesses that substantially reduced work ability. The risk of taking sick leave was increased when individuals had recently been exposed to problems in their relationship with a superior (OR 3.63; CI 1.44-9.14) or colleagues (OR 4.68; CI 1.43-15.29). Individuals were also more inclined to report sick on days when they expected a very stressful work situation than on a day when they were not under such stress (OR 2.27; CI 1.40-3.70). Exposure to problems in workplace relationships or a stressful work situation seems to be able to trigger reporting sick. Psychosocial work-environmental factors appear to have a short-term effect on individuals when deciding to report sick.

Sickness and sickness absence of remaining employees in a time of economic crisis: a study among employees of municipalities in Iceland.

Sigursteinsdóttir, Hjördís; Rafnsdóttir, Gudbjörg Linda

2015-05-01

This article focuses on sickness and sickness absence among employees of 20 municipalities in Iceland who remained at work after the economic crisis in October 2008. The aim was to examine the impact of economic crisis on sickness and sickness absence of "survivors" working within the educational system (primary school teachers and kindergarten teachers) and the care services (elderly care and care of disabled people) operated by the municipalities. The study was based on mixed methods research comprising a balanced panel data set and focus groups. An online survey conducted three times among 2356 employees of 20 municipalities and seven focus group interviews in two municipalities (39 participants). The generalized estimating equations (GEE) were used to analyze the quantitative data, and focused coding was used to analyze the qualitative data. The main finding showed that the economic crisis had negative health implications for the municipal employees. The negative effects grew stronger over time. Employee sickness and sickness absence increased substantially in both downsized and non-downsized workplaces. However, employees of downsized workplaces were more likely to be sick. Sickness and sickness absence were more common among younger than older employees, but no gender differences were observed. The study demonstrates the importance of protecting the health and well-being of all employees in the wake of an economic crisis, not only those who lose their jobs or work in downsized workplaces. This is important in the immediate aftermath of a crisis, but also for a significant time thereafter. This is of practical relevance for those responsible for occupational health and safety, as most Western countries periodically go through economic crises, resulting in strains on employees.

Occupational stress and incidence of sick leave in the Belgian workforce: the Belstress study

PubMed Central

Moreau, M; Valente, F; Mak, R; Pelfrene, E; de Smet, P; De Backer, G; Kornitzer, M

2004-01-01

Context: Sick leave is a major problem in public health. The Karasek demands/control/social support/strain (JDCS) model has been largely used to predict a wide range of health outcomes and to a lesser extent sickness absence. Study objective: The aim of the study was to test the predictive power of the JDCS model in relation with one year incidence of sick leave in a large cohort of workers. Design and setting: Cohort study conducted between 1994 and 1998 in 25 companies across Belgium. Participants: A total of 20 463 workers aged 35 to 59 years were followed up for sick leave during one year after the baseline survey. Outcomes: The outcomes were a high sick leave incidence, short spells (⩾7 days), long spells (⩾28 days), and repetitive spells of sickness absence (⩾3 spells/year). Main results: Independently from baseline confounding variables, a significant association between high strained jobs with low social support and repetitive spells of sickness absence was observed in both sexes with odds ratios of 1.32 (99% CI, 1.04 to 1.68) in men and 1.61 (99% CI, 1.13 to 2.33) in women. In men, high strained jobs with low social support was also significantly associated with high sick leave incidence, and short spells of sick leave with odds ratios of 1.38 (99% CI, 1.16 to 1.64) and 1.22 (99% CI, 1.05 to 1.44) respectively. Conclusions: Perceived high strain at work especially combined with low social support is predictive of sick leave in both sexes of a large cohort of the Belgian workforce. PMID:15143121

Work outcomes of sickness absence related to mental disorders: a systematic literature review

Objectives The purpose of this systematic literature review is to examine the current state of knowledge regarding the return-to-work outcomes of sickness absences related to mental disorders that increase costs borne by employers. We address two questions: (1) Based on the existing literature, from the employer's perspective, what are the relevant economic return-to-work outcomes for sickness absences related to mental disorders? and (2) From the employer's economic perspective, are there gaps in knowledge about the relevant return-to-work outcomes for sickness absences related to mental disorders? Setting The included studies used administrative data from either an employer, insurer or occupational healthcare provider. Participants Studies included working adults between 18 and 65 years old who had a sickness absence related to a mental disorder. Primary and secondary outcome measures The studies considered two general return-to-work outcome categories: (1) outcomes focusing on return-to-work and (2) outcomes focusing on sickness absence recurrence. Results A total of 3820 unique citations were identified. Of these, 10 studies were identified whose quality ranged from good to excellent. Half of the identified studies came from one country. The studies considered two characteristics of sickness absence: (1) whether and how long it took for a worker to return-to-work and (2) sickness absence recurrence. None of the studies examined return-to-work outcomes related to work reintegration. Conclusions The existing literature suggests that along with the incidence of sickness absence related to mental disorders, the length of sickness absence episodes and sickness absence recurrence (ie, number and time between) should be areas of concern. However, there also seems to be gaps in the literature regarding the work reintegration process and its associated costs. PMID:25023133

This register-based cohort study contains 2202 discordant twin pairs 18-64 years old, where one twin had sick leave due to a mental disorder 2005-2006. The end of the sick-leave spell was the start of follow-up for both twins. The twins were followed up for reoccurring sick-leave, disability pension and unemployment (> 180 days in a year), until December 2012. Analyses were censored for disability pension, death, emigration and old-age pension. Cox proportional hazards models with time-varying covariates were used to calculate hazard ratios with 95% confidence intervals (CI). Those with sick leave due to mental disorders had a 3.64 (CI: 3.24-4.08) times higher risk of reoccurring sick-leave within the first two years; after that, hazard ratios were attenuated and explained by genetic factors. The first year, they had 12.24 (CI: 8.11-18.46) times the risk of disability pension. The risk was attenuated but remained at 2.75 (CI: 2.07-3.65) after one year. The risk of unemployment was 1.99 (CI: 1.72-2.31) during the whole follow-up period. The risk of unemployment and disability pension was lower for those with stress-related than other mental disorders, this was less clear for recurrent reoccuring sick-leave. Sick leave due to mental disorders increased the risk of reoccurring sick-leave within two years, disability pension and unemployment, independent of genetics and shared environment.

To analyse the impact of sick-pay cuts on the use of sickness absence by employees of different socioeconomic groups. In 2009 cuts in sick pay were implemented in reaction to an economic crisis in Estonia. Nationwide health survey data from the years 2004, 2006, 2008, and 2010 were used to evaluate sickness absence among blue-collar and white-collar workers. The dataset comprised 7,449 employees of 20-64 years of age. Difference in prevalence of absentees before and after the reform was assessed using the chi-squared test. Odds ratios (OR) for sickness absence were calculated in a multivariate logistic regression model. After the reform, the proportion of blue-collar workers who had been on sick leave decreased from 51% to 40% (p<0.001) and among white-collar employees from 45% to 41% (p=0.026). This reduction had a similar pattern in all the subgroups of blue-collar employees as stratified according to gender, age, self-rated health, and presence of chronic disease, especially among those with low incomes; in white-collar employees it reached statistical significance only in those with good self-rated health (p=0.033). In a multivariate model the odds of having lower sickness absence were highly significant only in blue-collar employees (OR 0.63; 95% confidence interval 0.51-0.77, p<0.001). The cuts in sickness benefits had a major impact on the use of sickness absence by blue-collar employees with low salaries. This indicates that lower income was a major factor hindering the use of sick leave as these employees are most vulnerable to the loss of income. © 2014 the Nordic Societies of Public Health.

The Certification Board of Infection Control and Epidemiology, Inc (CBIC) is a voluntary autonomous multidisciplinary board that provides direction and administers the certification process for professionals who are responsible for the infection prevention and control program in a health care facility. The CBIC performs a practice analysis approximately every 4-5 years. The practice analysis is an integral part of the certification examination development process and serves as the backbone of the test content outline. In 2013, the CBIC determined that a practice analysis was required and contracted with Prometric to facilitate the process. The practice analysis was carried out in 2014 by a diverse group of subject matter experts from the United States and Canada. The practice analysis results showed a significant change in the number of tasks and associated knowledge required for the competent practice of infection prevention. As authorized by the CBIC, the test committee is currently reclassifying the bank of examination questions as required and is writing and reviewing questions based on the updated test specifications and content outline. The new content outline will be reflected in examinations that are taken beginning in July 2015. This iterative process of assessing and updating the certification examination ensures not only a valid competency tool but a true reflection of current practices.

Sickness absence has been shown to be a risk marker for severe future health outcomes, such as disability retirement and premature death. However, it is poorly understood how all-cause and diagnosis-specific sickness absence is reflected in subsequent physical and mental health functioning over time. The aim of this study was to examine the association of all-cause and diagnosis-specific sickness absence with subsequent changes in physical and mental health functioning among ageing municipal employees. Prospective survey and register data from the Finnish Helsinki Health Study and the Social Insurance Institution of Finland were used. Register based records for medically certified all-cause and diagnostic-specific sickness absence spells (>14 consecutive calendar days) in 2004-2007 were examined in relation to subsequent physical and mental health functioning measured by Short-Form 36 questionnaire in 2007 and 2012. In total, 3079 respondents who were continuously employed over the sickness absence follow-up were included in the analyses. Repeated-measures analysis was used to examine the associations. During the 3-year follow-up, 30% of the participants had at least one spell of medically certified sickness absence. All-cause sickness absence was associated with lower subsequent physical and mental health functioning in a stepwise manner: the more absence days, the poorer the subsequent physical and mental health functioning. These differences remained but narrowed slightly during the follow-up. Furthermore, the adverse association for physical health functioning was strongest among those with sickness absence due to diseases of musculoskeletal or respiratory systems, and on mental functioning among those with sickness absence due to mental disorders. Sickness absence showed a persistent adverse stepwise association with subsequent physical and mental health functioning. Evidence on health-related outcomes after long-term sickness absence may provide useful information for targeted interventions to promote health and workability.

The work ability index (WAI) is a frequently used tool in occupational health to identify workers at risk for a reduced work performance and for work-related disability. However, information about the prognostic value of the WAI to identify workers at risk for sickness absence is scarce. To investigate the prognostic value of the WAI for sickness absence, and whether the discriminative ability differs across demographic subgroups. At baseline, the WAI (score 7-49) was assessed among 1,331 office workers from a Dutch financial service company.

Objectives To support sustainability of the welfare society enhanced work retention is needed among those with impaired work ability. Partial health-related benefits have been introduced for this target. The aim was to estimate the effects of partial sick leave on transition to disability pension applying propensity score methods. Design Register-based cohort study. Setting Sample from the national sickness insurance registers representative of the Finnish working population (full-time workers) with long-term sickness absence due to musculoskeletal disorders, mental disorders, traumas or tumours. Participants All recipients of partial or full sickness benefit whose sick leave period had ended between 1 May and 31 December 2007 were included. The sample was limited to four most prevalent diagnostic groups—mental and musculoskeletal disorders, traumas and tumours. The total sample consisted of 1047 subjects on partial sick leave (treatment group) and 28 380 subjects on full sick leave (control group). A subsample (1017 and 25 249 subjects, respectively) was formed to improve the comparability of the two groups. Outcome measures A three-category measure and a binary measure for the occurrence of disability pension on the last day of 2008 were computed. Results Partial sickness benefit reduced the risk (change in absolute risk) of full disability pension by 6% and increased the risk of partial disability pension by 8% compared with full sick leave. The effects did not differ markedly for the two main diagnostic groups of musculoskeletal and mental disorders. In men, the use of full disability pension was reduced by 10% with a 5% increase in the use of partial disability pension, while in women the effects were close to those of the total sample. Conclusions Our findings suggest that combining work with partial sick leave may provide one means to increase work retention at population level. The use of partial sick leave could be encouraged among men. PMID:23144260

Objectives The aim of this study is to examine the role of coping styles in sickness absence. In line with findings that contrast the reactive–passive focused strategies, problem-solving strategies are generally associated with positive results in terms of well-being and overall health outcomes; our hypothesis is that such strategies are positively related to a low frequency of sickness absence and with short lengths (total number of days absent) and durations (mean duration per spell). Methods Using a prospective design, employees’ (N = 3,628) responses on a self-report coping inventory are used to predict future registered sickness absence (i.e. frequency, length, duration, and median time before the onset of a new sick leave period). Results and conclusions In accordance with our hypothesis, and after adjustment for potential confounders, employees with an active problem-solving coping strategy are less likely to drop out because of sickness absence in terms of frequency, length (longer than 14 days), and duration (more than 7 days) of sickness absence. This positive effect is observed in the case of seeking social support only for the duration of sickness absence and in the case of palliative reaction only for the length and frequency of absence. In contrast, an avoidant coping style, representing a reactive–passive strategy, increases the likelihood of frequent absences significantly, as well as the length and duration of sickness absence. Expression of emotions, representing another reactive–passive strategy, has no effect on future sickness absenteeism. The median time before the onset of a new episode of absenteeism is significantly extended for active problem-solving and reduced for avoidance and for a palliative response. The results of the present study support the notion that problem-solving coping and reactive–passive strategies are inextricably connected to frequency, duration, length and onset of sickness absence. Especially, active problem-solving decreases the chance of future sickness absence. PMID:17701200

The effect of social deprivation on local authority sickness absence rates.

There is an extensive body of research relating to the association between ergonomic and psychosocial factors on sickness absence rates. The impact of deprivation on health indices has also been extensively investigated. However, published research has not investigated the extent of any association between standard measures of deprivation and sickness absence and ill-health retirement rates. To establish if a relationship exists between standard measures of deprivation, used by the UK central government to determine regional health and social welfare funding, and sickness absence and ill-health early retirement rates in English local government employers. Local authority sickness absence rates for 2001-02 were regressed against the 2004 Indices of Multiple Deprivation in a multiple regression model that also included size and type of organization as independent variables. A second model using ill-health retirement as the dependent variable was also estimated. In the full regression models, organization size was not significant and reduced models with deprivation and organization type (depending on whether teachers were employed by the organization or not) were estimated. For the sickness absence model, the adjusted R(2) was 0.20, with 17% of the variation in sickness absence rates being explained by deprivation rank. Ill-health retirement showed a similar relationship with deprivation. In both models, the deprivation coefficients were highly significant: for sickness absence [t = -7.85 (P = 0.00)] and for ill-health retirement [t = -4.79 (P = 0.00)]. A significant proportion of variation in sickness absence and ill-health retirement rates in local government in England are associated with local measures of deprivation. Recognition of the impact of deprivation on sickness absence has implications for a number of different areas of work. These include target setting for Local Government Best Value Performance Indicators, history taking in sickness absence consultations and the role of deprivation as a confounding factor in sickness absence intervention studies.

Absences from work have considerable social and economic impact. In the education sector, the phenomenon is particularly worrying since teacher sick leave has an impact on the overall performance of the education system. Yet, available data are scarce. In April-June 2013, 2653 teachers responded to a population-based postal survey on their quality of life (enquête Qualité de vie des enseignants, MGEN Foundation/Ministry of education, response rate 53 %). Besides questions on work environment and health, teachers were asked to describe their eventual sick leave(s) since the beginning of the school year: duration, type and medical reasons. Self-reported information was reinforced by administrative data from ministerial databases and weighted to be extrapolated to all French teachers. Tobit models adjusted for individual factors of a private nature were used to investigate different occupational risk factors of teacher sick leave, taking into account both the estimated effect on the probability of sick leave and the length of it. More than one in three teachers (36 %) reported having had at least one day of sick leave since the beginning of the school year. Respiratory/ENT diseases were the leading reason for sick leave (37 %). However, and because sick leave duration depended on the underlying health problem, such diseases came in third place among justifications of sick leave days (14 %), far behind musculoskeletal problems (27 %) and neurological and psychological disorders (25 %). Tobit models suggested that some occupational factors significantly associated with the risk of sick leave may represent promising preventive targets, including high psychological demand, workplace violence and unfavorable socio-environmental context. Our study provides objective evidence about the issue of sick leave among French teachers, highlighting the usefulness of implementing actions to minimize its weight. To this end, the study findings point-out the importance of considering not only the probability of sick leave, but also its duration. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

Objectives The aim was to study whether a workplace-registered frequent short-term sick leave spell pattern was an early indicator of future disability pension or future long-term sick leave among municipal eldercare workers. Setting The municipal healthcare sector in the city of Aarhus, which is the second largest city in Denmark. Participants All elder care employees who worked the entire year of 2004 in the municipality of Aarhus, Denmark (N=2774). The employees’ sick leave days during 2004 were categorised into: 0–2 and 3–17 short (1–7 days) spells, 2–13 mixed short and long (8+ days) spells and long spells only. Student workers (n=180), employees who were absent due to maternal/paternal leave (n=536) and employees who did not work the entire year of 2004 (n=1218) were not included. Primary outcome Disability pension and long-term sick leave (≥8 weeks) were subsequently identified in a National register. The cumulative incidence proportion as a function of follow-up weeks was estimated using the Kaplan-Meier curve. The relative cumulative incidence (RR) of experiencing events within 352 weeks was analysed in a generalised linear regression model using the pseudo values method adjusted for age, occupation, unfavourable work factors and sick leave length. Results A frequent short-term and a mixed sick leave pattern showed RRs of being granted a disability pension of 2.08 (95% CI 1.00 to 4.35) and 2.61 (95% CI 1.33 to 5.12) compared with 0–2 short spells. The risk of long-term sick leave was significantly increased for all sick leave patterns compared with 0–2 short spells. Adding sick leave length to the models attenuated all RRs and they became non-significant. Conclusions Sick leave length was a better indicator of future workability than spell frequency. Preventive actions should target employees engaged in homecare. The more sick leave days the greater the preventive potential seems, irrespective of spell frequency. PMID:24508850

The incidence of pelvic girdle pain (PGP) in pregnancy is wide ranged depending on definition, the utilised diagnostic means, and the design of the studies. PGP during pregnancy has negative effects on activities of daily living and causes long sick leave, which makes it a major public health issue. Our objectives were to explore the frequency of sick leave in pregnancy due to PGP, assess the relationship between different types of pain-related activities of daily living, examine physical workload, type of work in relation to sick leave, and to explore factors that make women less likely to take sick leave for PGP. All women giving birth at the maternity ward of Stavanger University Hospital, Norway, were asked to participate and complete a questionnaire on demographic features, PGP, pain-related activities of daily living, sick leave in general and for PGP, frequency of exercising before and during pregnancy. Drawings of pelvic girdle and low back area were used for the localization of pain. PGP intensity was then rated retrospectively on a numerical rating scale. Non-parametric tests, multinomial logistic regression and sequential linear regression analysis were used in the statistical analysis. PGP is a frequent and major cause of sick leave during pregnancy among Norwegian women, which is also reflected in activities of daily living as measured with scores on all Oswestry disability index items. In the multivariate analysis of factors related to sick leave and PGP we found that work satisfaction, problems with lifting and sleeping, and pain intensity were risk factors for sick leave. In addition, women with longer education, higher work satisfaction and fewer problems with sitting, walking and standing, were less likely to take sick leave in pregnancy, despite the same pain intensity as women being on sick leave. A coping factor in pregnant women with PGP was discovered, most likely dependant on education, associated with work situation and/or work posture, which decreases sick leave. We recommend these issues to be further examined in a prospective longitudinal study since it may have important implications for sick leave frequency during pregnancy.

Traditional healers formalised?

PubMed

Van Niekerk, Jp

2012-02-23

Traditional healers are the first to be called for help when illness strikes the majority of South Africans. Their communities have faith in their ability to cure or alleviate conditions managed by doctors, and much more. A visit to such practitioners' websites (they are up with the latest advertising technology!) shows that they promise help with providing more power, love, security or money, protection from evil people and spirits, enhancing one's sex life with penis enlargement and vagina tightening spells, etc. Contemplating such claims, it is easy to be dismissive of traditional healers. But in this issue of the SAMJ Nompumelelo Mbatha and colleagues1 argue that the traditional healers' regulatory council, promised by an Act of Parliament, should be established, followed by (or preferably preceded by) formal recognition by employers of sick certificates issued by traditional healers. Can matters be so simply resolved? What does this mean for doctors and other formally recognised healthcare professionals, and how to respond to such claims and social pressures?

Women have higher sickness absence rate than men, but less is known of changes in this difference over time. We examined gender differences in sickness absence trends focusing on gender segregation in the labour market. We used large nationwide register data on Finnish wage earners aged 25-59 and generalized estimation equations based on repeated logistic regression to estimate the annual risk of sickness absence lasting at least 2 weeks. Between 2005 and 2013, the age-adjusted proportion (%) of employees with all-cause sickness absence decreased from the initial levels of 10.6 among men and 15.1 among women by 16.7 and 13.6%, respectively. Among both genders, the largest decrease in sickness absence coincided with the peak of the economic recession in 2009. In sickness absence due to all causes and musculoskeletal diseases, also the excess decrease among men mainly occurred in 2009, and in sickness absence due to mental disorders 2 years later. In sickness absence due to all causes and musculoskeletal diseases, the increasing gender difference was mainly attributable to a larger decrease in sickness absence at the time of the recession in male-dominated groups, such as in manual and manufacturing work, than in other sectors and occupational classes. In mental disorders, the increasing gender difference was partly attributable to a later smaller decrease in sickness absence among female-dominated lower non-manual and lower income employment groups. The increasing gender differences did not result from differential distributional changes in employment or sociodemographic factors among the employed male and female populations. In fact, widening of the gender gap in sickness absence due to all causes and musculoskeletal diseases would have been even larger without faster increase among women in the educational level and in non-manual employment. Sickness absence decreased especially in male-dominated employment groups, resulting in a larger decrease in absences among men compared with women. More research is needed to ascertain whether these differential changes are attributable, for example, to reduced willingness to seek medical advice or increased presenteeism in male-dominated groups, or to increased work pressures in female-dominated groups. Selection mechanisms, i.e. men's increased ill-health-related exit from work through other routes than sickness absence, also cannot be ruled out.

The importance of staying active instead of bed rest has been acknowledged in the management of musculoskeletal disorders (MSDs). This emphasizes the potential benefits of adjusting work to fit the employee's remaining work ability. Despite part-time sick leave being an official option in many countries, its effectiveness has not been studied yet. We have designed a randomized controlled study to assess the health effects of early part-time sick leave compared to conventional full-day sick leave. Our hypothesis is that if work time is temporarily reduced and work load adjusted at the early stages of disability, employees with MSDs will have less disability days and faster return to regular work duties than employees on a conventional sick leave. The study population will consist of 600 employees, who seek medical advice from an occupational physician due to musculoskeletal pain. The inclusion requires that they have not been on a sick leave for longer than 14 days prior to the visit. Based on the physician's judgement, the severity of the symptoms must indicate a need for conventional sick leave, but the employee is considered to be able to work part-time without any additional risk. Half of the employees are randomly allocated to part-time sick leave group and their work time is reduced by 40-60%, whereas in the control group work load is totally eliminated with conventional sick leave. The main outcomes are the number of days from the initial visit to return to regular work activities, and the total number of sick leave days during 12 and 24 months of follow-up. The costs and benefits as well as the feasibility of early part-time sick leave will also be evaluated. This is the first randomised trial to our knowledge on the effectiveness of early part-time sick leave compared to conventional full-time sick leave in the management of MSDs. The data collection continues until 2011, but preliminary results on the feasibility of part-time sick leave will be available already in 2008. The increased knowledge will assist in better decision making process regarding the management of disability related to MSDs.

To identify risk factors for absenteeism among workers with sick leave in an oil company. A case-control study (120 cases and 656 controls) nested in a retrospective cohort study following up all employees of an oil company in the North-Northeast of Brazil from 2007 to 2009. The response variable used to represent absenteeism with sick leave was the average incidence of sick leave, defined as the ratio between total sick days and potential working days in the period. Logistic regression techniques were used to investigate the association between average incidence of sick leave > 5.0% over the period and the variables sex, position, age, time at work, shift work, smoking, arterial hypertension, body mass index, physical activity, coronary risk, sleep, glycemia, non-managed diabetes, cardiovascular, digestive, musculoskeletal, neurological and neoplastic diseases, straining body positioning during work, satisfaction at work, relationship with management, and concentrated attention at work. Average incidence of sick leave higher than 5.0% in the cohort period was 15.5%. The logistic model revealed that workers with average incidence of sick leave higher than 5.0% were 2.6 times more likely to be female; 2.0 time more likely to be smokers; 1.8 time more likely to be former smokers; 2.2 times more likely to report abnormal sleep and 10.5 times more likely to report dissatisfaction with their than workers with average incidence of sick leave ≤ 5.0% in the period. In this population, female gender, being a smoker or a former smoker, reporting dissatisfaction with the job and reporting abnormal sleep are good predictors of occupational absenteeism with sick leave.

Medical physics educational programs (graduate education and residency education) are accredited by the Commission on Accreditation of Medical Physics Education Programs (CAMPEP), whereas medical physicists are certified by several organizations, the most familiar of which is the American Board of Radiology (ABR). In order for an educational program to become accredited or a medical physicist to become certified, the applicant must meet certain specified standards set by the appropriate organization.more » In this Symposium, representatives from both CAMPEP and the ABR will describe the process by which standards are established as well as the process by which qualifications of candidates for accreditation or certification are shown to be compliant with these standards. The Symposium will conclude with a panel discussion. Learning Objectives: Recognize the difference between accreditation of an educational program and certification of an individual Identify the two organizations primarily responsible for these tasks Describe the development of educational standards Describe the process by which examination questions are developed GS is Executive Secretary of CAMPEP.« less

Netchain coordinator services in pork supply chains including inspections according to the AMOR principle.

O'Hagan, Juliane; Ellebrecht, Susanne; Petersen, Brigitte

2013-11-01

This paper presents a mutual inspection concept between livestock production and processing, coordinated by a netchain coordinator acting as the service provider. The concept is based on an analysis of demand and offer with respect to the coordination of livestock health status certificates. Surveys have been conducted amongst piglet producers and pig fatteners (nfarmers=206) to reflect the demand for coordination services. Another survey amongst service providers (nproviders=21) determines the availability of these services. The results show a clear demand amongst farmers for the netchain coordinator services of livestock health status certificates. It has also been found that some service providers offer audit and monitoring procedures to enable certification with highly varying degrees of service quality. Based on the surveys, the joint organisation of livestock health status certificates between producer, fattener and service provider will be presented. It will be shown that for greater efficiency, coordination should be based on the principles of Alliances for the Mutual Organisation of Risk oriented inspection strategies (AMOR). To enable the mutual organisation of inspections, four key steps have been identified to develop and test AMOR as an innovative form of cooperation: (i) inspection design, (ii) responsibilities and tasks, (iii) information and communication structures, and (iv) shared cost and benefit model.

Daunton, Nancy G.

1990-01-01

Practical information on candidate animal models for motion sickness research and on methods used to elicit and detect motion sickness in these models is provided. Four good potential models for use in motion sickness experiments include the dog, cat, squirrel monkey, and rat. It is concluded that the appropriate use of the animal models, combined with exploitation of state-of-the-art biomedical techniques, should generate a great step forward in the understanding of motion sickness mechanisms and in the development of efficient and effective approaches to its prevention and treatment in humans.

Preventing recurrence of severe morning sickness

QUESTION A recent Motherisk article showed that initiating antinauseants even before symptoms start could prevent recurrence of severe morning sickness. In the study described, however, different physicians used different drugs. How can one be sure which drugs work? ANSWER The study of 26 women who had had severe morning sickness during previous pregnancies showed that using antiemetics before symptoms of morning sickness started appeared to prevent recurrence of severe morning sickness in subsequent pregnancies. Physicians in the United States used various antinauseant drugs. Physicians in Canada administered only one drug, the combination of doxylamine-pyridoxine (Diclectin®), to 12 women. Subanalysis of these 12 women revealed that pre-emptive use of doxylamine-pyridoxine significantly decreased the likelihood that severe morning sickness would recur. PMID:17279232

The tracking and communication division computer aided design/computer aided engineering system is now operational. The system is utilized in an effort to automate certain tasks that were previously performed manually. These tasks include detailed test configuration diagrams of systems under certification test in the ESTL, floorplan layouts of future planned laboratory reconfigurations, and other graphical documentation of division activities. The significant time savings achieved with this CAD/CAE system are examined: (1) input of drawings and diagrams; (2) editing of initial drawings; (3) accessibility of the data; and (4) added versatility. It is shown that the Applicon CAD/CAE system, with its ease of input and editing, the accessibility of data, and its added versatility, has made more efficient many of the necessary but often time-consuming tasks associated with engineering design and testing.

Purpose Transfer from on-site rehabilitation to the participant's daily environment is considered a weak link in the rehabilitation chain. The main objective of this study is to see if adding boosted telephone follow-up directly after completing an occupational rehabilitation program effects work participation. Methods A randomized controlled study included participants with chronic pain, chronic fatigue or common mental disorders on long-term sick leave. After completing 3½ weeks of acceptance and commitment therapy based occupational rehabilitation, participants were randomized to boosted follow-up or a control group before returning to their daily environment. The intervention was delivered over 6 months by on-site RTW coordinators mainly via telephone. Primary outcome was RTW categorized as participation in competitive work ≥1 day per week on average over 8 weeks. Results There were 213 participants of mean age 42 years old. Main diagnoses of sick leave certification were mental disorders (38%) and musculoskeletal disorders (30%). One year after discharge the intervention group had 87% increased odds (OR 1.87, 95% confidence interval 1.06-3.31, p = 0.031), of (re)entry to competitive work ≥1 day per week compared with the controls, with similar positive results for sensitivity analysis of participation half time (≥2.5 days per week). The cost of boosted follow-up was 390.5 EUR per participant. Conclusion Participants receiving boosted RTW follow-up had higher (re)entry to competitive work ≥1 day per week at 1 year when compared to the control group. Adding low-cost boosted follow-up by telephone after completing an occupational rehabilitation program augmented the effect on return-to-work.

Although sleep disturbances and fatigue are common conditions, frequently shown to be associated with sickness absence, only a few studies have prospectively investigated their independent effects on sickness absence, while adjusting for depressive symptoms. This study aims (i) to examine whether sleep disturbances and fatigue are independently related to the onset of register-based sickness absence of ≥ 3 weeks during a 1-year follow-up in a representative sample of the Danish workforce and (ii) to determine if possible associations are gender-specific. Data were used from the Danish Work Environment Cohort Study and linked with sickness absence data from the Danish National Register of Social Transfer Payments. A total of 6538 employees, 3178 men and 3360 women, were included in the analyses. Sleep disturbances predicted risk of sickness absence after adjustment for covariates, but lost statistical significance after further adjustment for depressive symptoms. Fatigue among men predicted risk of sickness absence [Hazard ratio (HR) = 1.25, 95% confidence intervals (CI) 1.00-1.56] after adjustment for covariates, depressive symptoms and sleep disturbances. Sleep disturbances in both genders and fatigue in women did not predict sickness absence after depressive symptoms were taken into account. In men, fatigue was significantly related to future sickness absence, also when adjusted for depressive symptoms and sleep disturbances. Further prospective studies are needed to explore the pathways from fatigue to sickness absence in more detail. The study suggests that early detection and treatment of fatigue in men should be high on the stakeholder's agenda.

Demonstrating the Potential for Dynamic Auditory Stimulation to Contribute to Motion Sickness

2014-01-01

Auditory cues can create the illusion of self-motion (vection) in the absence of visual or physical stimulation. The present study aimed to determine whether auditory cues alone can also elicit motion sickness and how auditory cues contribute to motion sickness when added to visual motion stimuli. Twenty participants were seated in front of a curved projection display and were exposed to a virtual scene that constantly rotated around the participant's vertical axis. The virtual scene contained either visual-only, auditory-only, or a combination of corresponding visual and auditory cues. All participants performed all three conditions in a counterbalanced order. Participants tilted their heads alternately towards the right or left shoulder in all conditions during stimulus exposure in order to create pseudo-Coriolis effects and to maximize the likelihood for motion sickness. Measurements of motion sickness (onset, severity), vection (latency, strength, duration), and postural steadiness (center of pressure) were recorded. Results showed that adding auditory cues to the visual stimuli did not, on average, affect motion sickness and postural steadiness, but it did reduce vection onset times and increased vection strength compared to pure visual or pure auditory stimulation. Eighteen of the 20 participants reported at least slight motion sickness in the two conditions including visual stimuli. More interestingly, six participants also reported slight motion sickness during pure auditory stimulation and two of the six participants stopped the pure auditory test session due to motion sickness. The present study is the first to demonstrate that motion sickness may be caused by pure auditory stimulation, which we refer to as “auditorily induced motion sickness”. PMID:24983752

Low back pain predict sickness absence among power plant workers

PubMed Central

Murtezani, Ardiana; Hundozi, Hajrije; Orovcanec, Nikola; Berisha, Merita; Meka, Vjollca

2010-01-01

Background: Low back pain (LBP) remains the predominant occupational health problem in most industrialized countries and low-income countries. Both work characteristics and individual factors have been identified as risk factors. More knowledge about the predictors of sickness absence from LBP in the industry will be valuable in determining strategies for prevention. Objectives: The aim of this longitudinal study was to investigate whether individual, work-related physical risk factors were involved in the occurrence of LBP sickness absence. Methods: A follow-up study was conducted among 489 workers, aged 18–65 years, at Kosovo Energetic Corporation in Kosovo. This cross-sectional study used a self-administered questionnaire to collect data on individual and work-related risk factors and the occurrence of LBP sickness absence. Logistic regression models were used to determine associations between risk factors and the occurrence of sickness absence due to LBP. Results: Individual factors did not influence sickness absence, whereas work-related physical factors showed strong associations with sickness absence. The main risk factors for sickness absence due to LBP among production workers were extreme trunk flexion (OR = 1.71, 95% CI = 1.05–2.78) as well as very extreme trunk flexion (OR = 6.04, 95% CI = 1.12–32.49) and exposure to whole-body vibration (OR = 1.75, 95% CI = 1.04–2.95). Conclusion: Reducing sickness absence from LBP among power plant workers requires focusing on the working conditions of blue-collar workers and risk factors for LBP. Increasing social support in the work environment may have effects in reducing sickness absence from LBP. PMID:21120081

Effect of passengers' active head tilt and opening/closure of eyes on motion sickness in lateral acceleration environment of cars.

PubMed

Wada, Takahiro; Yoshida, Keigo

2016-08-01

This study examined the effect of passengers' active head-tilt and eyes-open/eyes-closed conditions on the severity of motion sickness in the lateral acceleration environment of cars. In the centrifugal head-tilt condition, participants intentionally tilted their heads towards the centrifugal force, whereas in the centripetal head-tilt condition, the participants tilted their heads against the centrifugal acceleration. The eyes-open and eyes-closed cases were investigated for each head-tilt condition. In the experimental runs, the sickness rating in the centripetal head-tilt condition was significantly lower than that in the centrifugal head-tilt condition. Moreover, the sickness rating in the eyes-open condition was significantly lower than that in the eyes-closed condition. The results suggest that an active head-tilt motion against the centrifugal acceleration reduces the severity of motion sickness both in the eyes-open and eyes-closed conditions. They also demonstrate that the eyes-open condition significantly reduces the motion sickness even when the head-tilt strategy is used. Practitioner Summary: Little is known about the effect of head-tilt strategies on motion sickness. This study investigated the effects of head-tilt direction and eyes-open/eyes-closed conditions on motion sickness during slalom automobile driving. Passengers' active head tilt towards the centripetal direction and the eyes-open condition greatly reduce the severity of motion sickness.

Pana-Cryan, Regina; Rosa, Roger

2012-01-01

Objectives. We examined the association between US workers’ access to paid sick leave and the incidence of nonfatal occupational injuries from the employer’s perspective. We also examined this association in different industries and occupations. Methods. We developed a theoretical framework to examine the business value of offering paid sick leave. Data from the National Health Interview Survey were used to test the hypothesis that offering paid sick leave is associated with a reduced incidence of occupational injuries. We used data on approximately 38 000 working adults to estimate a multivariate model. Results. With all other variables held constant, workers with access to paid sick leave were 28% (95% confidence interval = 0.52, 0.99) less likely than workers without access to paid sick leave to be injured. The association between the availability of paid sick leave and the incidence of occupational injuries varied across sectors and occupations, with the greatest differences occurring in high-risk sectors and occupations. Conclusions. Our findings suggest that, similar to other investments in worker safety and health, introducing or expanding paid sick leave programs might help businesses reduce the incidence of nonfatal occupational injuries, particularly in high-risk sectors and occupations.

To assess the relationship between workplace bullying and sickness absenteeism in a large sample of Italian workers. A cross-sectional study conducted by means of questionnaires. In all, 8,992 subjects filled in a questionnaire to detect workplace bullying, the presence of work stress factors and days of sickness absence in the last year. Workplace bullying and psychosocial stressor were measured by the means of the CDL 2.0 questionnaire. Days of sickness absence reported by the subjects. On average, days of sickness absence were 7.4, and 7.2% of the respondents were defined as bullied. Results from logistic regression analyses showed that a workplace bullying was associated with more days of sickness absence after controlling for gender, age, professional qualification, company sector and juridical nature and other psychosocial factors (men: OR =1.62; women: OR =2.15). The present study confirms that workers exposed to a workplace bullying reported higher sickness absenteeism as compared with non-exposed subjects, also when a potentially highly stressful work environment is considered. The results of the present study support that workplace bullying may be viewed as an extreme stressful condition. Interventions to avoid workplace bullying not only favoure workers' health, but also avoid the company costs associated with workers' sickness absenteeism.

A narrative review on the similarities and dissimilarities between myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and sickness behavior.

Morris, Gerwyn; Anderson, George; Galecki, Piotr; Berk, Michael; Maes, Michael

2013-03-08

It is of importance whether myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a variant of sickness behavior. The latter is induced by acute infections/injury being principally mediated through proinflammatory cytokines. Sickness is a beneficial behavioral response that serves to enhance recovery, conserves energy and plays a role in the resolution of inflammation. There are behavioral/symptomatic similarities (for example, fatigue, malaise, hyperalgesia) and dissimilarities (gastrointestinal symptoms, anorexia and weight loss) between sickness and ME/CFS. While sickness is an adaptive response induced by proinflammatory cytokines, ME/CFS is a chronic, disabling disorder, where the pathophysiology is related to activation of immunoinflammatory and oxidative pathways and autoimmune responses. While sickness behavior is a state of energy conservation, which plays a role in combating pathogens, ME/CFS is a chronic disease underpinned by a state of energy depletion. While sickness is an acute response to infection/injury, the trigger factors in ME/CFS are less well defined and encompass acute and chronic infections, as well as inflammatory or autoimmune diseases. It is concluded that sickness behavior and ME/CFS are two different conditions.

To compare sickness absence and disability pension in a population-based cohort of women with breast cancer (n = 463) from 1 year pre-diagnosis until 3 years post-diagnosis with a matched control group (n = 2310), and to investigate predictors of sickness absence during the 2nd and 3rd year post-diagnosis. Following breast cancer, the proportion of disease-free women with sickness absence decreased post-diagnosis (1st-3rd year; 78%-31%-19%), but did not reach the pre-diagnostic level (14%; P < 0.05). Post-diagnosis, patients were more likely than controls to be sickness absent (1st-3rd year; P < 0.001). No between-group differences were observed for disability pension post-diagnosis (P > 0.05). Among patients, chemotherapy, baseline fatigue and pre-diagnosis sick days predicted sickness absence during the 2nd, 3rd, and 2nd and 3rd year post-diagnosis, respectively (P < 0.05). Breast cancer is associated with increased sickness absence 3 years post-diagnosis. In a clinical setting, prevention and treatment of side effects are important in reducing long-term consequences.

Doctors' sickness absence reduces the quality and continuity of patient care and is financially costly. Doctors have lower rates of sickness absence than other healthcare workers. To compare self-reported with recorded sickness absence in doctors in a UK National Health Service hospital trust. A retrospective questionnaire study. The main outcome measures were self-reported and trust-recorded sickness absence episodes of 4 days or more in two consecutive 6-month periods. The response rate was 82% (607/736). Self-reported sickness absence rates were 1.2% compared with a rate of 0.6% from trust-recorded data. There were 38 matched pairs of self-reported (mean duration: 18 days, standard deviation: 22 days) and trust-recorded (mean duration: 10 days, standard deviation: 17 days) sickness absence episodes of 4 days or more in the 12 months studied. A matched pairs t-test determined that the difference between the two means was significant (t = 2.57, P < 0.05). Doctors' sickness absence was significantly under-recorded in this study population. © The Author 2014. Published by Oxford University Press on behalf of the Society of Occupational Medicine.

Cabin location and the likelihood of motion sickness in cruise ship passengers.

PubMed

Gahlinger , P M

2000-01-01

The prevalence of motion sickness approaches 100% on rough seas. Some previous studies have reported a strong association between location on a ship and the risk of motion sickness, whereas other studies found no association. This study was undertaken to determine if there is a statistical association between the location of the passenger cabin on a ship and the risk of motion sickness in unadapted passengers. Data were collected on 260 passengers on an expedition ship traversing the Drake Passage between South America and Antarctica, during rough sea conditions. A standard scale was employed to record motion sickness severity. The risk of motion sickness was found to be statistically associated with age and sex. However, no association was found with the location of the passenger cabin. Previous research reporting a strong association of motion sickness and passenger location on a ship, studied passengers in the seated position. Passengers who are able to lie in a supine position are at considerably reduced risk of motion sickness. Expedition or cruise ships that provide ready access to berths, allow passengers to avoid the most nauseogenic positions. The location of the passenger cabin does not appear to be related to the likelihood of seasickness.

The aim of this qualitative study was to identify manageable organizational factors that could explain why some companies have low levels of sickness absence. There may be factors at company level that can be managed to influence levels of sickness absence, and promote health and a prosperous organization. 38 representative Swedish companies. The study included a total of 204 semi-structured interviews at 38 representative Swedish companies. Qualitative thematic analysis was applied to the interviews, primarily with managers, to indicate the organizational factors that characterize companies with low levels of sickness absence. The factors that were found to characterize companies with low levels of sickness absence concerned strategies and procedures for managing leadership, employee development, communication, employee participation and involvement, corporate values and visions, and employee health. The results may be useful in finding strategies and procedures to reduce levels of sickness absence and promote health. There is research at individual level on the reasons for sickness absence. This study tries to elevate the issue to an organizational level. The findings suggest that explicit strategies for managing certain organizational factors can reduce sickness absence and help companies to develop more health-promoting strategies.

Motion sickness history, food neophobia, and sensation seeking.

PubMed

Alley, Thomas R; Willet, Kathleen A; Muth, Eric R

2006-06-01

Motion sickness is believed to be caused by conflicting sensory signals, a situation that mimics the effects of ingesting certain toxins. Thus, one might suspect that individuals who have experienced a relatively high frequency of motion sickness may be particularly vigilant about avoiding anything that produces nausea, induding potentially nauseating toxins. Consequently, they may be more resistant to trying new foods, i.e., be more food neophobic, since unfamiliar foods can have unexpected adverse effects due to toxins or allergens. Likewise, many highly stimulating experiences can trigger motion sickness, so individuals who are more susceptible may be more prone to avoid such experiences, i.e., be less sensation seeking. Finally, it was expected that food neophobia would be more frequent in individuals low on sensation seeking tendencies. Self-reported motion sickness history in 308 adults (M= 18.8 yr.; SD = 1.6) was correlated with scores on the Arnett Inventory of Sensation Seeking and the Food Neophobia Scale. As predicted, greater history of motion sickness was associated with lower Sensation Seeking scores. Food Neophobia was not correlated with motion sickness history but, as expected, was negatively correlated (r = -.42) with scores on Sensation Seeking. Further research is recommended that measures actual sensitivity to motion sickness.

2011-03-01

Based on comprehensive administrative register data from Norway, we examine the determinants of sickness absence behavior; in terms of employee characteristics, workplace characteristics, panel doctor characteristics, and economic conditions. The analysis is based on a novel concept of a worker's steady state sickness absence propensity, computed from a multivariate hazard rate model designed to predict the incidence and duration of sickness absence for all workers. Key conclusions are that (i) most of the cross-sectional variation in absenteeism is caused by genuine employee heterogeneity; (ii) the identity of a person's panel doctor has a significant impact on absence propensity; (iii) sickness absence insurance is frequently certified for reasons other than sickness; and (iv) the recovery rate rises enormously just prior to the exhaustion of sickness insurance benefits.

Gordeeva, K.V.

1963-11-01

A study was made of the concentration of blood plasma fibrinogen in relation to the changes of fibrinogenase activity. Dogs with radiation sickness (severe, moderately severe, and mild) served as experimental animals. A rise of the blood plasma fibrinogen content was observed in dogs with severe and moderately severe radiation sickness. This phenomenon is especially pronounced at the height of radiation sickness. The activity of fibrinogenase in severe radiation sickness was considerably decreased at the initial period and at the height of the disease. The rise of fibrinogen content in severe and moderately severe radiation sickness should be regarded asmore » an adaptive reaction directed to control hemorrhages, not as the sequence of raduced fibrinogenase activity.

Emergency medical services (EMS) professionals often work long hours at multiple jobs and endure frequent exposure to traumatic events. The stressors inherent to the prehospital setting may increase the likelihood of experiencing burnout and lead providers to exit the profession, representing a serious workforce and public health concern. Our objectives were to estimate the prevalence of burnout, identify characteristics associated with experiencing burnout, and quantify its relationship with factors that negatively impact EMS workforce stability, namely sickness absence and turnover intentions. A random sample of 10,620 emergency medical technicians (EMTs) and 10,540 paramedics was selected from the National EMS Certification database to receive an electronic questionnaire between October, 2015 and November, 2015. Using the validated Copenhagen Burnout Inventory (CBI), we assessed burnout across three dimensions: personal, work-related, and patient-related. We used multivariable logistic regression modeling to identify burnout predictors and quantify the association between burnout and our workforce-related outcomes: reporting ten or more days of work absence due to personal illness in the past 12 months, and intending to leave an EMS job or the profession within the next 12 months. Burnout was more prevalent among paramedics than EMTs (personal: 38.3% vs. 24.9%, work-related: 30.1% vs. 19.1%, and patient-related: 14.4% vs. 5.5%). Variables associated with increased burnout in all dimensions included certification at the paramedic level, having between five and 15 years of EMS experience, and increased weekly call volume. After adjustment, burnout was associated with over a two-fold increase in odds of reporting ten or more days of sickness absence in the past year. Burnout was associated with greater odds of intending to leave an EMS job (personal OR:2.45, 95% CI:1.95-3.06, work-related OR:3.37, 95% CI:2.67-4.26, patient-related OR: 2.38, 95% CI:1.74-3.26) or the EMS profession (personal OR:2.70, 95% CI:1.94-3.74, work-related OR:3.43, 95% CI:2.47-4.75, patient-related OR:3.69, 95% CI:2.42-5.63). The high estimated prevalence of burnout among EMS professionals represents a significant concern for the physical and mental well-being of this critical healthcare workforce. Further, the strong association between burnout and variables that negatively impact the number of available EMS professionals signals an important workforce concern that warrants further prospective investigation.

Swedish parents are entitled to government paid benefits to take care of sick children. In this paper we show that the gender distribution of paid care for sick children is a good proxy for the gender division of household work. Using two examples we show that registry data on care for sick children is a useful data source for studies on gender…

Most workers with musculoskeletal disorders on sick leave often consult with regular health care before entering a specific work rehabilitation program. However, it remains unclear to what extent regular healthcare contributes to the timely return to work (RTW). Moreover, several studies have indicated that it might postpone RTW. There is a need to establish the influence of regular healthcare on RTW as outcome; "Does visiting a regular healthcare provider influence the duration of sickness absence and recurrent sick leave due to musculoskeletal disorders?". A cohort of workers on sick leave for 2-6 weeks due to a-specific musculoskeletal disorders was followed for 12 months. The main outcomes for the present analysis were: duration of sickness absence till 100% return to work and recurrent sick leave after initial RTW. Cox regression analyses were conducted with visiting a general health practitioner, physical therapist, or medical specialist during the sick leave period as independent variables. Each regression model was adjusted for variables known to influence health care utilization like age, sex, diagnostic group, pain intensity, functional disability, general health perception, severity of complaints, job control, and physical load at work. Patients visiting a medical specialist reported higher pain intensity and more functional limitations and also had a worse health perception at start of the sick leave period compared with those not visiting a specialist. Visiting a medical specialist delayed return to work significantly (HR = 2.10; 95%CI 1.43-3.07). After approximately 8 weeks on sick leave workers visiting a physical therapist returned to work faster than other workers. A recurrent episode of sick leave during the follow up quick was initiated by higher pain intensity and more functional limitations at the moment of fully return to work. Visiting a primary healthcare provider during the sickness absence period did not influence the occurrence of a new sick leave period. Despite the adjustment for severity of the musculoskeletal disorder, visiting a medical specialist was associated with a delayed full return to work. More attention to the factor 'labor' in the regular healthcare is warranted, especially for those patients experiencing substantial functional limitations due to musculoskeletal disorders.

Purpose To explore future diagnosis-specific sickness absence and disability pension among women with breast cancer compared with women without breast cancer. Also, to examine associations with disease-related and sociodemographic factors among those with breast cancer. Methods Longitudinal register data on 3,547 women living in Sweden (age 20 to 65 years) who were first diagnosed with breast cancer in 2005, and a matched comparison cohort (n = 14,188), were analyzed for the annual prevalence of diagnosis-specific sickness absence and disability pension over 5 years. Logistic regressions were used to explore associations of disease-related and sociodemographic factors with future sickness absence and disability pension among women with breast cancer. Results Immediately after being diagnosed with breast cancer, the proportion of women with sickness absence was high but decreased continuously from the 1st through 5th year after diagnosis (71%, 40%, 30%, 22%, and 19%, respectively). In comparison, the range for women without breast cancer was 17% to 11%, respectively. The higher prevalence of sickness absence after breast cancer was mainly a result of breast cancer diagnosis, not a mental diagnosis, or other somatic diagnoses. Advanced cancer at diagnosis, > 90 days sickness absence before diagnosis, low education, and being born outside Sweden were associated with higher odds ratios for sickness absence and disability pension (odds ratio range, 1.40 to 6.45). Conclusion The level of sickness absence increased substantially in women with breast cancer during the first year after diagnosis and approached the level of breast cancer-free women in the following years; however, even in the first year, most women were not on sickness absence for a substantial time, and even in high-risk groups, many were not on sickness absence or disability pension in the following years. Information about relatively low future sickness absence and disability pension levels can be used by patients when planning their work, by health care professionals, and by social insurance officers. Employers and Occupational Health Services need this information to adequately handle workplace adjustments.

In this longitudinal study the complex interplay between both job strain and bullying in relation to sickness absence was investigated. Following the "work environment hypothesis", which establishes several work characteristics as antecedents of bullying, we assumed that job strain, conceptualized by the Job-Demand-Control model, has an indirect relation with long-term sickness absence through bullying. The sample consisted of 2983 Belgian workers, aged 30 to 55 years, who participated in the Belstress III study. They completed a survey, including the Job Content Questionnaire and a bullying inventory, at baseline. Their sickness absence figures were registered during 1 year follow-up. Long-term sickness absence was defined as at least 15 consecutive days. A mediation analysis, using structural equation modeling, was performed to examine the indirect association of job strain through bullying with long-term sickness absence. The full structural model was adjusted for several possible confounders: age, gender, occupational group, educational level, company, smoking habits, alcohol use, body mass index, self-rated health, baseline long-term sickness absence and neuroticism. The results support the hypothesis: a significant indirect association of job strain with long-term sickness absence through bullying was observed, suggesting that bullying is an intermediate variable between job strain and long-term sickness absence. No evidence for the reversed pathway of an indirect association of bullying through job strain was found. Bullying was observed as a mediating variable in the relation between job strain and sickness absence. The results suggest that exposure to job strain may create circumstances in which a worker risks to become a target of bullying. Our findings are generally in line with the work environment hypothesis, which emphasizes the importance of organizational work factors in the origin of bullying. This study highlights that remodeling jobs to reduce job strain may be important in the prevention of bullying and subsequent sickness absence.

Differences in sickness absence between self-employed and employed doctors: a cross-sectional study on national sample of Norwegian doctors in 2010

Background Doctors have a low prevalence of sickness absence. Employment status is a determinant in the multifactorial background of sickness absence. The effect of doctors’ employment status on sickness absence is unexplored. The study compares the number of sickness absence days during the last 12 months and the impact of employment status, psychosocial work stress, self-rated health and demographics on sickness absence between self-employed practitioners and employed hospital doctors in Norway. Methods The study population consisted of a representative sample of 521 employed interns and consultants and 313 self-employed GPs and private practice specialists in Norway, who received postal questionnaires in 2010. The questionnaires contained items on sickness absence days during the last 12 months, employment status, demographics, self-rated health, professional autonomy and psychosocial work stress. Results 84% (95% CI 80 to 88%) of self-employed and 60% (95% CI 55 to 64%) of employed doctors reported no absence at all last year. In three multivariate logistic regression models with sickness absence as response variable, employment category was a highly significant predictor for absence vs. no absence, 1 to 3 days of absence vs. no absence and 4 to 99 days of absence vs. no absence), while in a model with 100 or more days of absence vs. no absence, there was no difference between employment categories, suggesting that serious chronic disease or injury is less dependent on employment category. Average or poor self-rated health and low professional autonomy, were also significant predictors of sickness absence, while psychosocial work stress, age and gender were not. Conclusion Self-employed GPs and private practice specialist reported lower sickness absence than employed hospital doctors. Differences in sickness compensation, and organisational and individual factors may to a certain extent explain this finding. PMID:24885230

Background The prevalence of musculoskeletal disorders (MSD) in the aluminium industry is high, and there is a considerable work-related fraction. More knowledge about the predictors of sickness absence from MSD in this industry will be valuable in determining strategies for prevention. The aim of this study was to analyse the relative impact of body parts, psychosocial and individual factors as predictors for short- and long-term sickness absence from MSD among industrial workers. Methods A follow-up study was conducted among all the workers at eight aluminium plants in Norway. A questionnaire was completed by 5654 workers at baseline in 1998. A total of 3320 of these participated in the follow-up study in 2000. Cox regression analysis was applied to investigate the relative impact of MSD in various parts of the body and of psychosocial and individual factors reported in 1998 on short-term and long-term sickness absence from MSD reported in 2000. Results MSD accounted for 45% of all working days lost the year prior to follow-up in 2000. Blue-collar workers had significantly higher risk than white-collar workers for both short- and long-term sickness absence from MSD (long-term sickness absence: RR = 3.04, 95% CI 2.08–4.45). Widespread and low back pain in 1998 significantly predicted both short- and long-term sickness absence in 2000. In addition, shoulder pain predicted long-term sickness absence. Low social support predicted short-term sickness absence (RR = 1.28, 95% CI 1.11–1.49). Conclusions Reducing sickness absence from MSD among industrial workers requires focusing on the working conditions of blue-collar workers and risk factors for low back pain and widespread pain. Increasing social support in the work environment may have effects in reducing short-term sickness absence from MSD. PMID:12956891

Work-related psychosocial events as triggers of sick leave - results from a Swedish case-crossover study

PubMed Central

2011-01-01

Background Although illness is an important cause of sick leave, it has also been suggested that non-medical risk factors may influence this association. If such factors impact on the period of decision making, they should be considered as triggers. Yet, there is no empirical support available. The aim was to investigate whether recent exposure to work-related psychosocial events can trigger the decision to report sick when ill. Methods A case-crossover design was applied to 546 sick-leave spells, extracted from a Swedish cohort of 1 430 employees with a 3-12 month follow-up of new sick-leave spells. Exposure in a case period corresponding to an induction period of one or two days was compared with exposure during control periods sampled from workdays during a two-week period prior to sick leave for the same individual. This was done according to the matched-pair interval and the usual frequency approaches. Results are presented as odds ratios (OR) with 95% confidence intervals (CI). Results Most sick-leave spells happened in relation to acute, minor illnesses that substantially reduced work ability. The risk of taking sick leave was increased when individuals had recently been exposed to problems in their relationship with a superior (OR 3.63; CI 1.44-9.14) or colleagues (OR 4.68; CI 1.43-15.29). Individuals were also more inclined to report sick on days when they expected a very stressful work situation than on a day when they were not under such stress (OR 2.27; CI 1.40-3.70). Conclusions Exposure to problems in workplace relationships or a stressful work situation seems to be able to trigger reporting sick. Psychosocial work-environmental factors appear to have a short-term effect on individuals when deciding to report sick. PMID:21429193

Objective Common mental disorders (CMDs) are among the leading causes of sick leave, and more knowledge on factors related to work participation and return-to-work (RTW) in CMDs is needed. The aim of this study was to investigate RTW-expectations and illness perceptions as predictors of benefit recipiency in CMDs. Design Study participants were enrolled in a randomised controlled trial and reported CMDs as a main obstacle for work participation. Three prespecified subgroups were included: people at risk of going on sick leave, people on sick leave (>3 weeks) or people on long-term benefits. Baseline questionnaire data and registry data at baseline and 6 months were used to investigate predictors of benefit recipiency at 6-month follow-up. Benefit recipiency included sickness benefits, disability pension, work assessment allowance and unemployment benefits. Results In this study, uncertain and negative RTW-expectations were strong predictors of benefit recipiency at 6 months follow-up. Illness perceptions predicted benefit recipiency in the unadjusted model, but not in the fully adjusted model. In the subgroup on sick leave, uncertain and negative RTW-expectations predicted benefit recipiency, while in the subgroup of people at risk of going on sick leave, negative RTW-expectations predicted benefit recipiency. In the subgroup on long-term benefits, only female gender predicted benefit recipiency. Conclusions For people with CMDs, uncertain and negative RTW-expectations predict later benefit recipiency, and expectations seem particularly important for those at risk of or on sick leave. For those at risk of sick leave, benefit recipiency at follow-up denoted a transition onto sick leave or long-term benefit, while those on sick leave had remained so or were receiving long-term benefits. Addressing RTW-expectations in occupational healthcare services or vocational rehabilitation might be beneficial in early stages or even prior to a sick leave episode.

During the last decades mortality has declined in patients with coronary heart disease due to improvements in treatments and changes in life style, resulting in more people living with chronic heart disease. This implies that focus on rehabilitation and re-integration to the work-force becomes increasingly important. Previous studies among healthy workers suggest that the psychosocial working environment is associated with sickness absence. Whether the psychosocial working environment plays a role for patients with existing cardiovascular disease on return to work and sickness absence is less studied. A cohort of patients under 67 years and treated with percutaneous coronary intervention (PCI) was established in 2006. Three months after the procedure the patients (n = 625) answered a questionnaire about their psychosocial working environment. Patients were followed in registers for the following year. We examined the association between psychosocial working environment and sickness absence at 3 months, 1 year and new sick-listings during the first year with logistic regression. A total of 528 patients had returned to work 3 months after the PCI, while 97 was still sick-listed. After 1 year one was dead, 465 were working and 85 were receiving health related benefits, while 74 had left the workforce permanently. A number of 106 patients were sick-listed during the whole first year or had left the workforce permanently. After the initial return to work, 90 experienced a new sickness absence during the first year while the remaining 429 did not. High work pace, low commitment to the workplace, low recognition (rewards) and low job control were associated with sickness absence at 3 months, but not after 1 year. Low job control as well as job strain (combination of high demands and low control) was associated with new sick-listings. The psychosocial working environment was associated with sickness absence 3 months after the PCI, but not 1 year after.

Four-year prospective cohort study. To find the incidence of sick leave because of neck and shoulder pain (NSP) in industrial workers, and its association with work and lifestyle risk factors. Longitudinal studies to investigate NSP incidence and risk factors are rare, and even fewer have been conducted in middle- and low-income countries. After inviting all full-time employees of an Iranian car manufacturing company with 18,031 employees to participate in a baseline study, they were followed for 4 years. New episodes of sick leave because of NSP have been calculated based on sickness absence registration between the years 2003 and 2007. The incidence was compared for participants and nonparticipants. The association between sick leave, physical, and psychosocial risk factors at work, and previous self-reported NSP, was calculated for the remaining population of baseline participants (12,184 employees) during a 4-year follow-up. During a 4-year follow-up of study subjects for the remaining participants of the baseline study, the incidence of sick leave was 0.8% (98 sick leave cases in 12,184 employees). For nonparticipants this incidence was 4.2% (130 cases in 3127 employees). In the final regression model for sick leave cases, the remaining factors for potential physical risk factors were repetitive work and sitting positions at work; for psychosocial factors unattractive work was the only significant remaining factor. The incidence of NSP based on sick leave is definitely very low compared with previous studies in high-income countries. This incidence varies between participants and nonparticipants. Risk factors for sick leave differ from risk factors for self-reported pain. A young population, job security, the insurance system, different health behaviors, and healthy worker bias, are all factors that may affect the results, and sick-leave as an outcome must be interpreted with more caution in middle- and low-income countries.

Background A number of previous studies have investigated various predictors for being granted a disability pension. The aim of this study was to test the efficacy of sick-leave track record as a predictor of being granted a disability pension in a large dataset based on subjects sampled from the general population and followed for a long time. Methods Data from five ongoing population-based Swedish studies was used, supplemented with data on all compensated sick leave periods, disability pensions granted, and vital status, obtained from official registers. The data set included 8,218 men and women followed for 16 years, generated 109,369 person years of observation and 97,160 sickness spells. Various measures of days of sick leave during follow up were used as independent variables and disability pension grant was used as outcome. Results There was a strong relationship between individual sickness spell duration and annual cumulative days of sick leave on the one hand and being granted a disability pension on the other, among both men and women, after adjustment for the effects of marital status, education, household size, smoking habits, geographical area and calendar time period, a proxy for position in the business cycle. The interval between sickness spells showed a corresponding inverse relationship. Of all the variables studied, the number of days of sick leave per year was the most powerful predictor of a disability pension. For both men and women 245 annual sick leave days were needed to reach a 50% probability of transition to disability. The independent variables, taken together, explained 96% of the variation in disability pension grantings. Conclusion The sick-leave track record was the most important predictor of the probability of being granted a disability pension in this study, even when the influences of other variables affecting the outcome were taken into account.

Objectives To examine the effect of the new legislation on partial sickness benefit on subsequent work participation of Finns with long-term sickness absence. Additionally, we investigated whether the effect differed by sex, age or diagnostic category. Design A register-based quasi-experimental study compared the intervention (partial sick leave) group with the comparison (full sick leave) group regarding their pre-post differences in the outcome. The preintervention and postintervention period each consisted of 365 days. Setting Nationwide, individual-level data on the beneficiaries of partial or full sickness benefit in 2008 were obtained from national sickness insurance, pension and earnings registers. Participants 1738 persons in the intervention and 56 754 persons in the comparison group. Outcome Work participation, measured as the proportion (%) of time within 365 days when participants were gainfully employed and did not receive either partial or full ill-health-related or unemployment benefits. Results Although work participation declined in both groups, the decline was 5% (absolute difference-in-differences) smaller in the intervention than in the comparison group, with a minor sex difference. The beneficial effect of partial sick leave was seen especially among those aged 45–54 (5%) and 55–65 (6%) and in mental disorders (13%). When the groups were rendered more exchangeable (propensity score matching on age, sex, diagnostic category, income, occupation, insurance district, work participation, sickness absence, rehabilitation periods and unemployment, prior to intervention and their interaction terms), the effects on work participation were doubled and seen in all age groups and in other diagnostic categories than traumas. Conclusions The results suggest that the new legislation has potential to increase work participation of the population with long-term sickness absence in Finland. If applied in a larger scale, partial sick leave may turn out to be a useful tool in reducing withdrawal of workers from the labour market due to health reasons. PMID:25539780

Profile analysis of after-effects experienced during exposure to several virtual reality environments

Motion sickness symptoms are an unwanted by-product of exposure to virtual environments. This problem is not new and was reported in the early flight simulators and experiments on ego motions and vection. The cardinal symptom of motion sickness is, of course, vomiting, but this symptom is ordinarily preceded by a variety of other symptoms. In his classic studies of motion sickness conducted before and during World War II, G. R. Wendt introduced a three point scale to score motion sickness beyond a vomit/no vomit dichotomy. Later, Navy scientists developed a Motion Sickness Questionnaire (MSQ), originally for use in a slowly rotating room. In the last 20 years the MSQ has been used in a series of studies of air, sea, and space sickness. Only recently, however, has it been appreciated that symptom patterns in the MSQ are not uniform but vary with the way sickness is induced. In seasickness, for example, nausea is the most prominent symptom. In Navy simulators, however, the most common symptom is eye strain, especially when cathode ray tubes are employed in the simulation. The latter result was obtained in a survey of over 1,500 pilot exposures. Using this database, Essex scientists conducted a factor analysis of the MSQ. We found that signs and symptoms of motion sickness fell mainly into three clusters: 1) oculomotor disturbance, 2) nausea and related neurovegetative problems, and 3) disorientation, ataxia, and vertigo. We have since rescored the MSQ results obtained in Navy simulators in terms of these three components. We have also compared these and other profiles obtained from three different vitual reality systems to profiles obtained in sea sickness, space sickness, and alcohol intoxication. We will show examples of these various profiles and point out simularities and differences among them which indicate aspects of what might be called 'virtual-reality sickness'.

Long-term sick-leave is a major public health problem, but data on its incidence in Japan are scarce. We aimed to present reference data for long-term sick-leave among private sector employees in Japan. The study population comprised employees of 12 companies that participated in the Japan Epidemiology Collaboration on Occupational Health Study. Details on medically certified sick-leave lasting ≥30 days were collected from each company. Age- and sex-specific incidence rate of sick-leave was calculated for the period of April 2012 to March 2014. A total of 1422 spells in men and 289 in women occurred during 162,989 and 30,645 person-years of observation, respectively. The three leading causes of sick-leave (percentage of total spells) were mental disorders (52%), neoplasms (12%), and injury (8%) for men; and mental disorders (35%), neoplasms (20%), and pregnancy-related disease (14%) for women. Incidence rate of sick-leave due to mental disorders was relatively high among men in their 20s-40s but tended to decrease with age among women. Incidence rate of sick-leave due to neoplasms started to increase after age 50 in men and after age 40 in women, making neoplasms the leading cause of sick-leave after age 50 for women and after age 60 for men and the second leading cause after age 40 for women and after age 50 for men. Pregnancy-related disease was the second leading cause of sick-leave among women aged 20-39 years. These results suggest that mental disorder, neoplasms, and pregnancy-related disease are the major causes of long-term sick-leave among private sector employees in Japan.

The objective of the study was to examine diagnosis-specific sickness absences of different lengths as predictors of disability retirement in different occupational classes. Register-based prospective cohort study up to 8 years of follow-up. A 70% random sample of the non-retired Finnish population aged 25-62 at the end of 2006 was included (n=1 727 644) and linked to data on sickness absences in 2005 and data on disability retirement in 2007-2014. Cox proportional hazards regression was utilised to analyse the association of sickness absence with the risk of all-cause disability retirement during an 8-year follow-up. The risk of disability retirement increased with increasing lengths of sickness absence in all occupational classes. A long sickness absence was a particularly strong predictor of disability retirement in upper non-manual employees as among those with over 180 sickness absence days the HR was 9.19 (95% CI 7.40 to 11.40), but in manual employees the HR was 3.51 (95% CI 3.23 to 3.81) in men. Among women, the corresponding HRs were 7.26 (95% CI 6.16 to 8.57) and 3.94 (95% CI 3.60 to 4.30), respectively. Adjusting for the diagnosis of sickness absence partly attenuated the association between the length of sickness absence and the risk of disability retirement in all employed groups. A long sickness absence is a strong predictor of disability retirement in all occupational classes. Preventing the accumulation of sickness absence days and designing more efficient policies for different occupational classes may be crucial to reduce the number of transitions to early retirement due to disability. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Extending working life into older age groups is discussed in many countries. However, there is no knowledge about how this affects rates of sick leave. The aim of this work was to investigate rates of sick leave among people in paid work after retirement age and if such rates have changed over time. Swedish nationwide register data on people aged >65 years and living in Sweden in 1995, 2000, 2005 and 2010 were analysed. All people with a sufficiently high work income to be eligible for public sick leave benefits were included. The proportions in paid work and compensated rates of sick leave for people aged 66-70 and ≥71 were analysed by sex, educational level, country of birth, living area, and employment type and sector. The percentage of people in paid work at ages 66-70 years increased from <10% in 1995 to 24% in 2010 and among those aged ≥71 years from 2.7% in 1995 to 3.5% in 2010. The rates of sick leave among working people aged 66-70 years were 3.3% in 1995 and 2.4% in 2010 and for people aged ≥71 years the rates of sick leave were 2.2% in 1995 and 0.2% in 2010. Women had higher rates of sick leave than men in 2005 and 2010, but lower in 1995 and 2000. In 2010, the rates of sick leave were similar between employees and the self-employed, and higher among employees in the public sector than among employees in the private sector. Rates of sick leave among workers aged >65 years were lower in 2010 than in 1995, despite much higher rates of labour market participation in 2010.

OBJECTIVE To identify risk factors for absenteeism among workers with sick leave in an oil company. METHODS A case-control study (120 cases and 656 controls) nested in a retrospective cohort study following up all employees of an oil company in the North-Northeast of Brazil from 2007 to 2009. The response variable used to represent absenteeism with sick leave was the average incidence of sick leave, defined as the ratio between total sick days and potential working days in the period. Logistic regression techniques were used to investigate the association between average incidence of sick leave > 5.0% over the period and the variables sex, position, age, time at work, shift work, smoking, arterial hypertension, body mass index, physical activity, coronary risk, sleep, glycemia, non-managed diabetes, cardiovascular, digestive, musculoskeletal, neurological and neoplastic diseases, straining body positioning during work, satisfaction at work, relationship with management, and concentrated attention at work. RESULTS Average incidence of sick leave higher than 5.0% in the cohort period was 15.5%. The logistic model revealed that workers with average incidence of sick leave higher than 5.0% were 2.6 times more likely to be female; 2.0 time more likely to be smokers; 1.8 time more likely to be former smokers; 2.2 times more likely to report abnormal sleep and 10.5 times more likely to report dissatisfaction with their than workers with average incidence of sick leave ≤ 5.0% in the period. CONCLUSIONS In this population, female gender, being a smoker or a former smoker, reporting dissatisfaction with the job and reporting abnormal sleep are good predictors of occupational absenteeism with sick leave.

Background and purpose - Little is know about patterns of sick leave in connection with total hip and knee joint replacement (THR and TKR) in patients with osteoarthritis (OA). Patients and methods - Using registers from southern Sweden, we identified hip and knee OA patients aged 40-59 years who had a THR or TKR in the period 2004-2012. Patients who died or started on disability pension were excluded. We included 1,307 patients with THR (46% women) and 996 patients with TKR (56% women). For the period 1 year before until 2 years after the surgery, we linked individual-level data on sick leave from the Swedish Social Insurance Agency. We created a matched reference cohort from the general population by age, birth year, and area of residence (THR: n = 4,604; TKR: n = 3,425). The mean number of days on sick leave and the proportion (%) on sick leave 12 and 24 months before and after surgery were calculated. Results - The month after surgery, about 90% of patients in both cohorts were on sick leave. At the two-year follow-up, sick leave was lower for both cohorts than 1 year before surgery, except for men with THR, but about 9% of the THR patients and 12-17% of the TKR patients were still sick-listed. In the matched reference cohorts, sick leave was constant at around 4-7% during the entire study period. Interpretation - A long period of sick leave is common after total joint replacement, especially after TKR. There is a need for better knowledge on how workplace adjustments and rehabilitation can facilitate the return to work and can postpone surgery.

Leptin mediates seasonal variation in some but not all symptoms of sickness in Siberian hamsters

Many seasonally breeding species, including Siberian hamsters (Phodopus sungorus), exhibit seasonal variation in sickness responses. One hypothesis regarding the mechanism of this variation is that sickness intensity tracks an animal's energetic state, such that sickness is attenuated in the season that an animal has the lowest fat stores. Energetic state may be signaled via leptin, an adipose hormone that provides a signal of fat stores. Siberian hamsters respond to extended housing in short, winter-like days by reducing fat stores and leptin levels, relative to those housed in long, summer-like days. Sickness responses are also attenuated in short-day hamsters as compared to long-day hamsters. We hypothesized that leptin provides a physiological signal by which seasonally breeding animals modulate sickness responses, such that animals with higher leptin levels show increased sickness intensity. To test this, we provided short-day hamsters with a long-day-like leptin signal and assessed their responses to lipopolysaccharide (LPS), a sickness-inducing antigen. We compared these responses to short-day vehicle-, long-day vehicle-, and long-day leptin-treated hamsters. Unexpectedly, LPS induced a hypothermic response (rather than fever) in all groups. Short-day vehicle-treated hamsters exhibited the greatest LPS-induced hypothermia, and leptin treatment attenuated this response, making hypothermia more long-day-like. Contrary to our hypothesis, short-day leptin-treated hamsters showed the least pronounced LPS-induced anorexia among all groups. These results suggest that leptin may mediate some but not all aspects of seasonal sickness variation in this species. Future studies should be targeted at determining roles of other energetic hormones in regulating seasonal sickness response variation. PMID:25461974

To investigate associations between psychosocial job demands, job resources and cases of registered long-term sickness absence among nursing staff in the eldercare services. Research has shown that psychosocial work environment exposures predict sickness absence in healthcare settings. However, only few studies have longitudinally investigated associations between specific job demands and job resources and risk of long-term sickness absence. Questionnaire data were collected in 2004 and 2005 among all employees in the eldercare services in 35 Danish municipalities and were followed in a National register on payment of sickness absence compensation for a 1-year follow-up period (N = 7921). Three psychosocial job demands - emotional demands, quantitative demands and role conflicts - and three job resources - influence, quality of leadership and team climate - were investigated to predict risk of sickness absence for eight or more consecutive weeks in the follow-up period. Data were analysed using Cox proportional hazards model. A percentage of 6·5 of the respondents were absent for eight or more consecutive weeks during follow-up. The analyses showed that emotional demands, role conflicts, influence, quality of leadership and team climate were significantly associated with risk of long-term sickness absence. In an analysis with mutual adjustment for all job demands and job resources, influence constituted the strongest predictor of long-term sickness absence (negative association). Job demands and job resources are significantly associated with risk of long-term sickness absence. Interventions aimed at improving the psychosocial work environment may, therefore, contribute towards preventing long-term sickness absence in the eldercare services. © 2011 Blackwell Publishing Ltd.

Considering the costs incurred by sickness absence and the implications for the workers' quality of life, a fast return to work (RTW) is important. Self-efficacy (SE) seems to be an important predictor of RTW for employees with mental health problems. The predictive value of return-to-work self-efficacy (RTW-SE) has not been examined in employees on long-term sickness absence due to any cause. The aim of this study is to investigate whether RTW-SE is a predictor of time to RTW in long-term sick-listed employees with all-cause sickness absence. Furthermore, the relative contribution of RTW-SE in predicting RTW will be examined compared to health-related, job-related and personal factors. In a longitudinal study, sick-listed employees who were currently on sick leave for more than 4 weeks filled out a self-report questionnaire. Demographics, health-related, personal, and job-related factors, and RTW-SE were measured. Employees were followed for 2 years to determine the duration until full RTW. Cox proportional hazards regression analyses were used to identify factors associated with time to RTW. Data were collected from 493 sick-listed employees. RTW-SE was a significant predictor of RTW. In a multivariate model, low RTW-SE, the thought of not being able to work while having symptoms (illness behaviour) and having chronic medical conditions were predictors of a longer duration until RTW. When guiding long-term sick-listed employees, it is important to focus on factors such as SE and illness behaviour, instead of just focusing on the symptoms of the sick-listed employee.

This study investigated the association between the work ability index (WAI) and the single-item question on work ability among women working in human service organizations (HSO) currently on long-term sick leave. It also examined the association between the WAI and the single-item question in relation to sick leave, symptoms, and health. Predictive values of the WAI, the changed WAI, the single-item question and the changed single-item question were investigated for degree of sick leave, symptoms, and health. This cohort study comprised 324 HSO female workers on long-term (>60 days) sick leave, with follow-ups at 6 and 12 months. Participants responded to questionnaires. Data on work ability, sick leave, health, and symptoms were analyzed with regard to associations and predictability. Spearman correlation and mixed-model analysis were performed for repeated measurements over time. The study showed a very strong association between the WAI and the single-item question among all participants. Both the WAI and the single-item question showed similar patterns of associations with sick leave, health, and symptoms. The predictive value for the degree of sick leave and health-related quality of life (HRQoL) was strong for both the WAI and the single-item question, and slightly less strong for vitality, neck pain, both self-rated general and mental health, and behavioral and current stress. This study suggests that the single-item question on work ability could be used as a simple indicator for assessing the status and progress of work ability among women on long-term sick leave.

The purpose of this study was to use objective registry data to prospectively investigate the effects of quick returns (QR, <11 hours of rest between shifts) and night shifts on sick leave. A total of 1538 nurses (response rate =41.5%) answered questionnaires on demographics and personality and provided consent to link this information to registry data on shift work and sick leave from employers' records. A multilevel negative binomial model was used to investigate the predictive effect of exposure to night shifts and QR every month for 1 year, on sick leave the following month. Exposure to QR the previous month increased the risk for sick leave days (incidence rate ratio (IRR)=1.066, 95% CI 1.022 to 1.108, p<0.01) and sick leave spells (IRR=1.059, 95% CI 1.025 to 1.097, p<0.001) the following month, whereas night shifts did not. 83% per cent of the nurses experienced QR within a year, and on average they were exposed to 3.0 QR per month (SD=1.6). Personality characteristics associated with shift work tolerance (low on morningness, low on languidity and high on flexibility) were not associated with sick leave, and did not moderate the relationship between QR and sick leave. We found a positive linear relationship between QR and sick leave. Avoiding QR may help reduce workers' sick leave. The restricted recovery opportunity associated with QR may give little room for beneficial effects of individual characteristics usually associated with shift work tolerance.

Pain and emotional exhaustion are prevalent conditions with consequences for sickness absence. Although they often co-occur, their combined associations with sickness absence are poorly understood. This study aimed to examine the separate and combined associations of pain and emotional exhaustion with subsequent sickness absence. The data were derived from a cross-sectional questionnaire survey sent to 40 to 60-year-old employees of the City of Helsinki in 2000 to 2002 (n = 6457) linked with the City of Helsinki personnel register information on sickness absence (3 years on from the survey). Self-certified (1-3 days) and medically certified sickness absence spells (4-14 days, more than 14 days) were used as outcomes. Acute and chronic pain and emotional exhaustion were measured in a questionnaire survey. For the purposes of this study, sickness absence and pain variables were merged to form a new variable with 6 mutually exclusive categories. The main statistical method was negative binomial regression analysis. The synergy index was used to estimate the interaction. Among women, acute and chronic pain with and without emotional exhaustion predicted sickness absence, particularly absence lasting for more than 2 weeks, whereas emotional exhaustion alone did not. The associations persisted when further adjusted for socioeconomic and sociodemographic factors, health-related behaviors, and somatic and mental health. A synergistic interaction effect was found for co-occurring pain and emotional exhaustion on medically certified sickness absence. The results for men were mainly similar, but less stable. In order to tackle sickness absence, special attention should be paid to the prevention and treatment of employees with co-occurring pain and emotional exhaustion.

Human factors issues in performing life science experiments in a 0-G environment

NASA Technical Reports Server (NTRS)

Gonzalez, Wayne

1989-01-01

An overview of the environmental conditions within the Spacelab and the planned Space Station Freedom is presented. How this environment causes specific Human Factors problems and the nature of design solutions are described. The impact of these problems and solutions on the performance of life science activities onboard Spacelab (SL) and Space Station Freedom (SSF) is discussed. The first area highlighted is contamination. The permanence of SSF in contrast to the two-week mission of SL has significant impacts on crew and specimen protection requirements and, thus, resource utilization. These requirements, in turn impose restrictions on working volumes, scheduling, training, and scope of experimental procedures. A second area is microgravity. This means that all specimens, materials, and apparatus must be restrained and carefully controlled. Because so much of the scientific activity must occur within restricted enclosures (gloveboxes), the provisions for restraint and control are made more complex. The third topic is crewmember biomechanics and the problems of movement and task performance in microgravity. In addition to the need to stabilize the body for the performance of tasks, performance of very sensitive tasks such as dissection is difficult. The issue of space sickness and adaption is considered in this context.

An appraisal of the value of vitamin B12 in the prevention of motion sickness

NASA Technical Reports Server (NTRS)

Kohl, R. L.; Lacey, C. L.; Homick, J. L.

1983-01-01

It has been suggested that vitamin B12 given by intramuscular injection can significantly reduce the occurrence of motion sickness in susceptible individuals (Banks, 1980). Since it is known that B12 influences the metabolism of histidine and choline, dietary precursors to neurotransmitters with established roles in motion sickness, an experimental evaluation has been undertaken of the efficacy of B12 in the prevention of motion sickness induced by controlled coriolis simulation. Subjects executed standardized head movements at successively higher rpm until a malaise III endpoint was reached. Following two baseline tests with this motion stressor, subjects received a B12 injection, a second injection two weeks later, and a final motion sickness test three weeks later. No significant differences in the susceptibility to motion sickness were noted after B12.

The impact of downsizing on remaining workers' sickness absence.

PubMed

Østhus, Ståle; Mastekaasa, Arne

2010-10-01

It is generally assumed that organizational downsizing has considerable negative consequences, not only for workers that are laid off, but also for those who remain employed. The empirical evidence with regard to effects on sickness absence is, however, inconsistent. This study employs register data covering a major part of the total workforce in Norway over the period 2000-2003. The number of sickness absence episodes and the number of sickness absence days are analysed by means of Poisson regression. To control for both observed and unobserved stable individual characteristics, we use conditional (fixed effects) estimation. The analyses provide some weak indications that downsizing may lead to slightly less sickness absence, but the overall impression is that downsizing has few if any effects on the sickness absence of the remaining employees.

To investigate the associations between demographic variables and sick leave use. We analyzed sick leave use among civil servants at a federal agency (FA) from 2004 to 2012 by demographic and FA-specific variables. We used a mixed methods approach and type III analysis to build a descriptive model of sick leave proportions and demographic variables. Sick absenteeism usage varied significantly (variation of greater than one sick day per year) by sex, Emergency Operations Center response tier, length of service at the FA, age, and general schedule pay grade level. Our final descriptive model contained age, sex, response tier and an interaction term between age and sex. Future studies should examine these associations on smaller time scales, perhaps breaking the data down by month or day of the week.

Sickness absence is of considerable concern in both Norway and Denmark. Labour Force Surveys indicate that absence in Norway is about twice that in Denmark and twice that of the mean reported by the Organisation for Economic Co-operation and Development. This study compares absence patterns according to age, percentage of employment, and occupation between municipal employees in the health and care sectors in two municipalities in Norway and Denmark. Data recorded in the personnel registers of the municipalities of Kristiansand, Norway and Aarhus, Denmark were extracted for the years 2004 and 2008, revealing 3498 and 7751 employee-years, respectively. We calculated absence rates together with number of sick leave episodes, and their association with the above-mentioned covariates. Gender-specific comparative descriptive statistics and negative binomial regression analysis were performed. The sickness absence rate in women was 11.3% in Norway (95% confidence interval [CI] 11.2-11.4) and 7.0% in Denmark (95% CI 7.0-7.1) whereas mean number of sick leave episodes among women was 2.4 in Denmark, compared to 2.3 in Norway (p = 0.02). Young employees in Denmark had more sick leave episodes than in Norway. Proportion of absentees was higher in Denmark compared to Norway (p < 0.0001). The finding of that more employees in Denmark have more frequent, but shorter sick leave episodes compared to Norway, for whatever reasons, may indicate that more frequent sick leaves episodes prevent higher sick leaves rates.

A series of studies has demonstrated that sick children fare better when their parents are present. To examine working conditions that determine whether parents can spend time with and become involved in the care of their children when they are sick. Survey with a multivariate analysis of factors influencing parental care of sick children. Mixed-income urban working parents aged 26 to 29 years participating in the Baltimore Parenthood Study. Only 42% of working parents in our sample cared for their young children when they became sick. A multivariate logistic regression analysis was conducted to predict which parents stayed at home when their children were sick. Those parents who had either paid sick or vacation leave were 5.2 times as likely to care for their children themselves when they were sick. Of parents with less than a high school education, 17% received paid leave, compared with 57% of parents with a general equivalency diploma, 76% of parents with a high school diploma, and 92% of parents with more than a high school education (P<.001). The finding that many parents were unable to care for their sick children themselves is important for pediatric care. While low-income children are more likely to face marked health problems and to be in need of parental care, they are more likely to live in households in which parents lack paid leave and cannot afford to take unpaid leave.

Prediction of helicopter simulator sickness

Machine learning methods from artificial intelligence are used to identify information in sampled accelerometer signals and associative behavioral patterns which correlates pilot simulator sickness with helicopter simulator dynamics. These simulators are used to train pilots in fundamental procedures, tactics, and response to emergency conditions. Simulator sickness induced by these systems represents a risk factor to both the pilot and manufacturer. Simulator sickness symptoms are closely aligned with those of motion sickness. Previous studies have been performed by behavioral psychologists using information gathered with surveys and motor skills performance measures; however, the results are constrained by the limited information which ismore » accessible in this manner. In this work, accelerometers were installed in the simulator cab, enabling a complete record of flight dynamics and the pilot's control response as a function of time. Given the results of performance measures administered to detect simulator sickness symptoms, the problem was then to find functions of the recorded data which could be used to help predict the simulator sickness level and susceptibility. Methods based upon inductive inference were used, which yield decision trees whose leaves indicate the degree of simulator-induced sickness. The long-term goal is to develop a gauge'' which can provide an on-line prediction of simulator sickness level, given a pilot's associative behavioral patterns (learned expectations). This will allow informed decisions to be made on when to terminate a hop and provide an effective basis for determining training and flight restrictions placed upon the pilot after simulator use. 6 refs., 6 figs.« less

The aim of this study was to investigate whether a multidimensional public-private partnership intervention, focussing on improving the quality and efficiency of sickness benefit case management, reduced the sickness benefit duration and the duration until self-support. We used a difference-in-difference (DID) design with six intervention municipalities and 12 matched control municipalities in Denmark. The study sample comprised 282,103 sickness benefit spells exceeding four weeks. The intervention group with 110,291 spells received the intervention, and the control group with 171,812 spells received ordinary sickness benefit case management. Using register data, we fitted Cox proportional hazard ratio models, estimating hazard ratios (HR) and confidence intervals (CI). We found no joint effect of the intervention on the sickness benefit duration (HR 1.02, CI 0.97-1.07) or the duration until self-support (HR 0.99, CI 0.96-1.02). The effect varied among the six municipalities, with sickness benefit HRs ranging from 0.96 (CI 0.93-1.00) to 1.13 (CI 1.08-1.18) and self-support HRs ranging from 0.91 (CI 0.82-1.00) to 1.11 (CI 1.06-1.17). Compared to receiving ordinary sickness benefit management the intervention had on average no effect on the sickness benefit duration or duration until self-support. However, the effect varied considerably among the six municipalities possibly due to differences in the implementation or the complexity of the intervention.

The objective of this study was to analyze the variation of pregnancy-related sickness absence among employed women according to age, occupation, and degree of male-female domination within occupations. Data from a prospective study of all new sick-leave spells exceeding 7 d in 1985 and 1986 in the county of Ostergötland, Sweden, were related to the population at risk, through the Swedish Medical Birth Register. The subjects included in the analysis were all 7000 employed women that gave birth in 1985 and 1986, of which some 3000 were sick-listed at least once with pregnancy-related diagnoses. There was little difference in the pregnancy-related sickness absence between the age groups. The age-standardized rate for sick leaves involving pregnancy-related diagnoses differed substantially between occupations. Women in the metal industry had the highest rates; those employed in administration, banking, and insurance had the lowest. White-collar occupations generally had lower rates and blue-collar occupations higher rates, with some exceptions (eg, in saw mills, farming, and the chemical industry). Gender-integrated occupations had the lowest sick-leave rate, while extremely male-dominated jobs had the highest. The latter association remained after adjustment for occupational area. There were considerable differences between occupational groups in the rates of sick leaves involving pregnancy-related diagnoses. Some differences were related to physical load of the jobs being done, but not all. It seems important to consider also male-female domination within a job with respect to such sick leaves.

Associations between psychosocial work factors and sickness absence were investigated in a cross-sectional study of 833 daytime workers. Participants completed a questionnaire regarding psychosocial work factors using the US National Institute for Occupational Safety and Health Generic Job Stress Questionnaire (job control, quantitative workload, cognitive demands, variance in workload, intragroup conflict, intergroup conflict, supervisor support, coworker support, family support, job satisfaction and depressive symptoms) and the number of days of sickness absence within the previous year. Multivariate analyses of covariance with age and occupation as covariates (MANCOVA) were used to test the relationships between psychosocial work factors and sickness absence stratified by sex. In men, the age-adjusted MANCOVA showed that, quantitative workload was highest in the 0.5-4.5 d of sickness absence group (p<0.001). However, the levels of stress reactions (job satisfaction and depressive symptoms) in this group were almost identical to the levels recorded in the no sickness absence group. In contrast, low levels of job control (p<0.01), supervisor support (p<0.05), and job satisfaction (p<0.01) and higher symptoms of depression (p<0.001) were associated with 5 d or more sickness absence. In women, only high job satisfaction was associated with 5 d or more sickness absence (p<0.10). This study suggests that appropriate use of sickness absence at times of being exposed to high quantitative workload may help male workers to recover from stressful situations.

Motion sickness in ancient China: Seasickness and cart-sickness.

2016-07-19

To find and analyze descriptions of motion sickness in Chinese historical sources. Databases and dictionaries were searched for various terms for seasickness and travel sickness, which were then entered into databases of full texts allowing selection of relevant passages from about the third to the 19th century ad. Already in 300 ad the Chinese differentiated cart-sickness, particularly experienced by persons from the arid north of China, from a ship-illness experienced by persons from the south, where rivers were important for transportation and travel. In the Middle Ages, a third form of motion sickness was called litter-influence experienced by persons transported in a bed suspended between 2 long poles. The ancient Chinese recognized the particular susceptibility of children to motion sickness. Therapeutic recommendations include drinking the urine of young boys, swallowing white sand-syrup, collecting water drops from a bamboo stick, or hiding some earth from the middle of the kitchen hearth under the hair. The Chinese medical classics distinguished several forms of travel sickness, all of which had their own written characters. The pathophysiologic mechanism was explained by the medicine of correspondences, which was based on malfunctions within the body, its invasion by external pathogens like wind, or the deficit or surfeit of certain bodily substances such as the life force Qi. The concept of motion as the trigger of sickness initially appeared in a chapter on warding off the influence of demons and corpses, e.g., ancient magic and beliefs. © 2016 American Academy of Neurology.

The objective of this study was to investigate the relationship between managerial leadership and self-reported sickness absence/presenteeism among Swedish men and women. Five thousand one hundred and forty-one Swedish employees, 56% of the participants in a nationally representative sample of the Swedish working population, were included in this cross-sectional questionnaire study. The leadership dimensions measured were five subscales of a standardized leadership questionnaire (Global Leadership and Organizational Behaviour Effectiveness Programme): Integrity, Team integration, Inspirational leadership, Autocratic leadership, and Self-centred leadership. Multiple logistic regression analyses were conducted, adjusting for factors in private life, employment category, labour-market sector, working conditions, self-reported general health, and satisfaction with life in general. Inspirational leadership was associated with a lower rate of short spells of sickness absence (<1 week) for both men and women. Autocratic leadership was related to a greater amount of total sick days taken by men. Sometimes showing integrity was associated with higher rate of sickness absence >1 week among men, and seldom showing integrity was associated with more sickness presenteeism among women. Managers performing Team integration were sometimes associated with women taking fewer short (<1 week) and long (>1 week) spells of sickness absence. Adjustment for self-reported general health did not alter these associations for men, but did so to some extent for women. Managerial leadership was found to be relevant for the understanding of sickness absence in the Swedish working population. There were distinctive gender differences.

The nine variables are serum uric acid, red cell count, environmental temperature at the launch site, serum phosphate, urine osmolality, serum thyroxine, sitting systolic blood pressure, calculated blood volume, and serum chloride. Using two methods of cross-validation on the original samples (jackknife and a stratefied random subsample), these variables enable the prediction of space sickness incidence (NONE or SICK) with 80 percent sickness and space severity (NONE, MILD, MODERATE, of SEVERE) with 59 percent success by one method of cross-validation and 67 percent by another method. Addition of a tenth variable, hours spent in the Weightlessness Environment Training Facility (WETF) did not improve the prediction of space sickness incidences but did improve the prediction of space sickness severity to 66 percent success by the first method of cross-validation of original samples and to 71 percent by the second method. Results to date suggest the presence of predisposing physiologic factors to space sickness that implicate fluid shift etiology. The data also suggest that prior exposure to fluid shift during WETF training may produce some circulatory pre-adaption to fluid shifts in weightlessness that results in a reduction of space sickness severity.

Research investigating frequent sickness absence (3 or more episodes per year) is scarce and qualitative research from the perspective of frequent absentees themselves is lacking. The aim of the current study is to explore awareness, determinants of and solutions to frequent sickness absence from the perspective of frequent absentees themselves. We performed a qualitative study of 3 focus group discussions involving a total of 15 frequent absentees. Focus group discussions were audiotaped and transcribed verbatim. Results were analyzed with the Graneheim method using the Job Demands Resources (JD-R) model as theoretical framework. Many participants were not aware of their frequent sickness absence and the risk of future long-term sickness absence. As determinants, participants mentioned job demands, job resources, home demands, poor health, chronic illness, unhealthy lifestyles, and diminished feeling of responsibility to attend work in cases of low job resources. Managing these factors and improving communication (skills) were regarded as solutions to reduce frequent sickness absence. The JD-R model provided a framework for determinants of and solutions to frequent sickness absence. Additional determinants were poor health, chronic illness, unhealthy lifestyles, and diminished feeling of responsibility to attend work in cases of low job resources. Frequent sickness absence should be regarded as a signal that something is wrong. Managers, supervisors, and occupational health care providers should advise and support frequent absentees to accommodate job demands, increase both job and personal resources, and improve health rather than express disapproval of frequent sickness absence and apply pressure regarding work attendance.

Although teaching is considered a high-stress profession, research on stress-related outcomes among teachers, such as absence from work due to illness (i.e. sickness absence), remains scarce. It is possible that teachers are not a homogeneous group but include subgroups with particularly high risk of sickness absence, such as special education teachers. To examine differences in sickness absence rates between special and general education teachers in a large cohort of 2291 Finnish lower secondary school teachers. Register data on teachers' job titles, sociodemographic characteristics and sickness absence were obtained from 10 municipal employers' registers. Indices of sickness absence included rates of short-term (1-3 days) and long-term (>3 days) absence spells during 2003-05. With multi-level models adjusted for individual- and school-level covariates, we found that although the absolute level of sickness absence was higher among women than among men, male special education teachers were at a 1.36-fold (95% CI: 1.15-1.61) increased risk of short-term and a 1.33-fold (95% CI: 1.01-1.76) increased risk of long-term sickness absence compared with male teachers in general education. Among women, there were no differences in sickness absence between special and general education teachers. Compared to male teachers in general education, male teachers in special education appear to have an excess risk of absence from work due to illness. Future studies should examine the causes for this excess risk and determine the need for preventive interventions.

The workplace is used as a setting for interventions to prevent and reduce sickness absence, regardless of the specific medical conditions and diagnoses. To give an overview of the general effectiveness of active workplace interventions aimed at preventing and reducing sickness absence. We systematically searched PubMed, Embase, Psych-info, and ISI web of knowledge on 27 December 2011. Inclusion criteria were (i) participants over 18 years old with an active role in the intervention, (ii) intervention done partly or fully at the workplace or at the initiative of the workplace and (iii) sickness absence reported. Two reviewers independently screened articles, extracted data and assessed risk of bias. A narrative synthesis was used. We identified 2036 articles of which, 93 were assessed in full text. Seventeen articles were included (2 with low and 15 with medium risk of bias), with a total of 24 comparisons. Five interventions from four articles significantly reduced sickness absence. We found moderate evidence that graded activity reduced sickness absence and limited evidence that the Sheerbrooke model (a comprehensive multidisciplinary intervention) and cognitive behavioural therapy (CBT) reduced sickness absence. There was moderate evidence that workplace education and physical exercise did not reduce sickness absence. For other interventions, the evidence was insufficient to draw conclusions. The review found limited evidence that active workplace interventions were not generally effective in reducing sickness absence, but there was moderate evidence of effect for graded activity and limited evidence for the effectiveness of the Sheerbrooke model and CBT.

The association between sickness presenteeism, defined as going to work despite illness, and different health outcomes is increasingly being recognized as a significant and relevant area of research. However, the long term effects on future employee health are less well understood, and to date there has been no review of the empirical evidence. The aim of this systematic review was to present a summary of the sickness presenteeism evidence so far in relation to health and wellbeing over time. Eight databases were searched for longitudinal studies that investigated the consequences of workplace sickness presenteeism, had a baseline and at least one follow-up point, and included at least one specific measure of sickness presenteeism. Of the 453 papers identified, 12 studies met the eligibility criteria and were included in the review. We adopted a thematic approach to the analysis because of the heterogeneous nature of the sickness presenteeism research. The majority of studies found that sickness presenteeism at baseline is a risk factor for future sickness absence and decreased self-rated health. However, our findings highlight that a consensus has not yet been reached in terms of physical and mental health. This is because the longitudinal studies included in this review adopt a wide variety of approaches including the definition of sickness presenteeism, recall periods, measures used and different statistical approaches which is problematic if this research area is to advance. Future research directions are discussed. Copyright © 2016 Elsevier Ltd. All rights reserved.

Objectives The aim of the article is to investigate the differences in sickness present and non-sickness present in the group of disabled health care professionals. Methods Data were gathered from all disabled health care professionals suffering from invalidity of category II or III who were identified in the research among all health care professionals at the University Medical Centre Ljubljana and who were employed there in the period between 1 January 2010 and 31 December 2010. Each employee obtained a questionnaire composed of three standardized international questionnaires. Results There were 248 disabled workers of the II. and III. category of invalidity among the participants. Disabled sickness present reported to have more chronic diseases than disabled non-sickness present (OR = 57.0; 95% CI = 24.4–133.2), lower salary when on sick leave (OR = 13.1; 95% CI = 5.7–30.2) and poor self-rated health (OR = 5.8; 95% CI = 2.7–12.3). Conclusions The prerequisite for sickness presence among disabled workers is their chronic bad health. It is also formally recognized with the degree of disability. Economic factors are among the most important to direct disabled workers towards sickness presence. The results indicate that workplaces are not adapted to disabled workers in regard to their limitations. PMID:27669513

Motion sickness: a negative reinforcement model.

PubMed

Bowins, Brad

Theories pertaining to the "why" of motion sickness are in short supply relative to those detailing the "how." Considering the profoundly disturbing and dysfunctional symptoms of motion sickness, it is difficult to conceive of why this condition is so strongly biologically based in humans and most other mammalian and primate species. It is posited that motion sickness evolved as a potent negative reinforcement system designed to terminate motion involving sensory conflict or postural instability. During our evolution and that of many other species, motion of this type would have impaired evolutionary fitness via injury and/or signaling weakness and vulnerability to predators. The symptoms of motion sickness strongly motivate the individual to terminate the offending motion by early avoidance, cessation of movement, or removal of oneself from the source. The motion sickness negative reinforcement mechanism functions much like pain to strongly motivate evolutionary fitness preserving behavior. Alternative why theories focusing on the elimination of neurotoxins and the discouragement of motion programs yielding vestibular conflict suffer from several problems, foremost that neither can account for the rarity of motion sickness in infants and toddlers. The negative reinforcement model proposed here readily accounts for the absence of motion sickness in infants and toddlers, in that providing strong motivation to terminate aberrant motion does not make sense until a child is old enough to act on this motivation.

To test an interactional model on the associations between work stressors, perceived stress, alcohol consumption and sickness absence. Cross-sectional survey. The study was part of a Worksite Health Project including an Employee Assistance Programme and a Health Promotion Programme in the Netherlands. Participants were blue-collar workers from two Municipal Garbage Collecting Departments and white-collar workers from a Pharmaceutical Company (N = 471). Measurements included socio-demographic characteristics (gender, age, education, marital status), work stressors, perceived stress, alcohol consumption and sickness absence. Type of work-site (blue- or white-collar) and smoking behaviour were used as covariates. Regression analyses resulted in three major findings. First, in the presence of stress, abstinence increased the risk of sickness absence compared with moderate drinking. We failed to find a significant relationship between excessive drinking and sickness absence. Secondly, stress mediated the associations between stressor and alcohol consumption, and between stressor and sickness absence, although stressors also directly predicted sickness absence. The association between abstinence and sickness absence could reflect medical problems of abstainers or a lack of skills for coping with stress. The failure to find a significant detrimental effect of excessive drinking may have been due to use of a low threshold for excessive drinking and/or low power. Prospective studies are needed to gain insight in causal relationships between the variables concerned.

To evaluate the effect of a weight-gain restriction programme for obese pregnant women on sickness absence days and pregnancy benefit days during pregnancy and postpartum. A prospective, controlled intervention study. The Swedish Social Security Agency's records were utilized to compile sickness absence and pregnancy benefit information. Antenatal care clinics in the south-east of Sweden. One hundred fifty-five obese pregnant women who participated in a weight restriction program with weekly structured motivational and behavioural talks combined with aqua-aerobics during pregnancy. A total of 193 obese pregnant women with no intervention served as controls. Sickness absence benefits and pregnancy benefits expressed as a percentage. On average women in the intervention group had 76.68 total full days of sickness absence benefit compared with 53.09 days in the control group. Total full days of pregnancy benefits were 39.66% days and 41.41% for the intervention and control groups respectively. For the women who were on sick leave there were no differences between the groups in the amount of days taken. Given the complexity of factors that have an influence on sickness absence leave, it is possible that programmes that do not address the influence of social aspects and attitudes towards sickness absence have limited effect.

Little is known about the factors that control individual differences in susceptible to motion sickness. A serendipitous observation in our laboratory that most Chinese subjects become motion sick prompted this study. We used a rotating optokinetic drum to provoke motion sickness and compared gastric responses and symptom reports of Chinese, European-American, and African-American subjects. There was no difference in the responses of European-American and African-American subjects; however, Chinese subjects showed significantly greater disturbances in gastric activity and reported significantly more severe symptoms. We suggest that this hypersusceptibility presents a natural model for the study of physiological mechanisms of nausea and other symptoms of motion sickness.
