Changes in memory and attention during and after occupational rehabilitation: A longitudinal study.

BACKGROUND: There is need for more knowledge about the relationship between work and cognitive functioning in sick-listed individuals. OBJECTIVE: This study investigated whether the degree of work participation is relevant for recovery of cognitive functioning in sick-listed individuals. METHODS: 177 occupational rehabilitation participants and 70 controls participated in a non-randomised, longitudinal study. Participants completed computerised cognitive tests targeting sustained attention and working memory at start and end of rehabilitation and 3 and 12 months after rehabilitation. The change score performance in attention and memory between start and end, start and 3 months and 12 months was compared in individuals on sick leave 100-75%, 74-40% and 39-0% (three sick leave groups) of the time in the year after rehabilitation, and a control group not being on sick leave. Fixed effect analysis of covariance adjusting for education and work ability was used. RESULTS: The sick leave group 100-75% had significantly lower score on work ability compared to the other groups at baseline. The main findings indicated that the sick leave group 39-0% improved significantly more in sustained attention compared to the sick leave group 100-75% between start and end of rehabilitation and from start of rehabilitation to 3 and 12 months after. CONCLUSION: The degree of work participation seems relevant to recovery of the cognitive function sustained attention in sick-listed individuals. These findings encourage work rehabilitation clinicians, work consultants and employers to develop RTW plans which take into account that graded employment influence cognitive functioning.

Helpful elements in a brief work-oriented intervention targeting musculoskeletal and mental health literacy.

Musculoskeletal and mental health complaints are common in the general population and frequent reasons for healthcare utilization and work absence. Illness perceptions, coping expectancies, rumination and self-stigma are important factors in the management of these health complaints and factors closely linked to health literacy (HL). The aims of the study were to identify helpful elements in a brief intervention (BI) targeting HL regarding common musculoskeletal and mental health complaints and to identify patient perceptions of how the intervention was helpful and whether it affected their subsequent coping. Three focus group interviews with 14 patients were conducted. Systematic text condensation was used for the analysis, supported by the health literacy skill (HLS) framework to sharpen the focus on intervention elements related to the acquisition and utilization of HLSs. Results revealed the importance of receiving comprehensible health information and guidance, the use of metaphors to create recognizable narratives and the use of practical examples and exercises. Normalizing the experienced health complaints, together with a safe and accommodating clinical environment, facilitated the change process. The BI initiated processes that contributed to acceptance, resilience and empowerment, aiding work-life balance and return to work. The study presents authentic narratives of value for future focus in BI.

Workplace Inclusion of People With Health Issues, Immigrants, and Unemployed Youths-A Qualitative Study of Norwegian Leaders' Experiences.

Aim: To explore leaders' perceptions and experiences of facilitators and barriers for successful workplace inclusion of immigrants, unemployed youths, and people who are outside the labor market due to health issues. Methods: Semi-structured individual interviews with 16 leaders who actively engaged in inclusion work, representing different occupations, were conducted. Systematic Text Condensation was used to structure the analysis. Results: The participating leaders emphasized that job match, including their perception of workers' motivation, respect for workplace policies, and the availability of appropriate accommodation at the workplace, facilitated work inclusion. An active public support system providing professional and financial support to workers and leaders was also an important facilitating factor. The leaders emphasized that their perception of workers' lack of motivation for the job was the most important barrier in their own hiring and inclusion engagement. Successful inclusion depended on all workers acknowledging responsibility for and contributing to an inclusive work environment. Being open and willing to discuss challenges was an important part of making the inclusion work. In addition, leadership qualities, such as empathy, patience, and a non-judgmental attitude, appeared as a hallmark among these leaders who actively engaged in inclusion work. Conclusion: Workplace inclusion of this population of marginalized people was facilitated by job match, mutual respect, commitment, and trust, as well as financial and practical support from the public support system. Leaders' inclusion practices were furthermore affected by personal attitudes and perceptions of social responsibility. Even so, successful workplace inclusion was presented as a two-way street. Leaders have the main responsibility in initiating a respectful and trusting relationship, but both the worker and the leader needs to contribute to make the relationship thrive.

What is the effect of independent medical evaluation on days on sickness benefits for long-term sick listed employees in Norway? A pragmatic randomised controlled trial, the NIME-trial.

BACKGROUND: Independent medical evaluations are used to evaluate degree and reason for work disability, uncertainty around the functional status, and/or the employee's rehabilitation potential in several jurisdictions, but not in Norway. The main aim of this trial was to test the return to work effect of independent medical evaluation (IME) (summoning and consultation) compared to treatment as usual (TAU) in Norway, for workers who have been on continuous sick leave for 6 months. METHODS: This was a pragmatic randomised controlled trial including all employees aged 18-65 years, sick-listed by their general practitioner and on full or partial sick leave for the past 26 weeks in Hordaland County, Norway in 2015/16. Trial candidates were drawn from a central register at the Norwegian Labour and Welfare Administration at 22 weeks of sick leave. Pregnant women, individuals with cancer or dementia diagnoses, those with secret address, employed by NAV or sick listed by the specialist health services were excluded. Separate regression analyses were conducted to investigate the "intention-to-treat" and "treatment on the treated" effects, using the ordinary least squares and instrumental variable methods, respectively. RESULTS: After exemption based on predefined exclusion criteria, 5888 individuals were randomised to either IME (n = 2616) or TAU (n = 2599). The final intervention group constitutes 1698 individuals, of which 937 attended the IME consultation. No baseline differences were found between the IME and TAU group regarding gender, age, and previous sick leave. Individuals attending the IME were older than those who cancelled the appointment ((47/45), p = 0.006) and those who did not show up without cancelling ((47/42), p < 0.001). Mainly the IME physician agreed with the regular GP upon level of sick leave. In cases with different assessments, the difference tended to be towards a lower sick leave level. There were no intention to treat or treatment on the treated effect on days of sick leave after randomisation during follow up. CONCLUSIONS: Overall, the analyses showed no effect of IME on changes in sick leave for sick listed employees. This result was consistent for those who were offered an IME consultation (intention to treat) and those who undertook an IME consultation (treatment on the treated).

eHealth interventions to facilitate work participation: a scoping review.

OBJECTIVE: The objective of this scoping review was to identify studies combining the concepts of eHealth and work participation for sick-listed employees across diagnostic groups in health care and workplace contexts. INTRODUCTION: There is an increased demand for better health care services and technologies, and eHealth is proposed as a useful tool to improve efficiency and reduce costs. eHealth functions at the intersection of medical informatics, public health, and business, and may be a promising solution for managing the process of return to work among employees on sick leave. Assessment of work outcomes is essential in evaluating the effectiveness of health services, and there is a need to map the research literature on existing eHealth interventions to facilitate work participation. INCLUSION CRITERIA: This scoping review considered studies combining two core concepts: eHealth and work participation. It considered studies on eHealth interventions for employees (18 to 65 years of age) on sick leave due to any type of diagnosis or disability, conducted by any stakeholder in workplace or health care contexts and in any country. Empirical data from both quantitative and qualitative studies were included. METHODS: Published and unpublished studies from January 1, 2008, to August 21, 2020, written in English were included in this review. The search was conducted in MEDLINE, Scopus, Embase, PsycINFO, WHO clinical registry, and ClinicalTrials.gov. A three-step search strategy was followed. Data extraction was performed by two independent reviewers and undertaken using an extraction tool developed specifically for the scoping review objectives. RESULTS: This review identified 15 studies eligible for inclusion. Four studies delivered the eHealth intervention by telephone, while 10 interventions were web-based. Of the web-based interventions, five had a blended approach, such as website and email support, or website and social media platforms. One study used an app-based intervention. Only eight studies targeted employees sick-listed due to common sick leave diagnoses, such as common mental disorders and musculoskeletal disorders. The workplace context was the target of the eHealth intervention in seven studies, although the intervention was still delivered by health personnel such as therapists or occupational physicians. Collaboration on individual cases between the health professional, employer, and employee to facilitate work participation seemed to be rare. Four studies reported both a theoretical and an empirical base for the intervention used. CONCLUSIONS: This review demonstrated that the use of eHealth interventions to facilitate work participation is limited, and there is a need for future studies on the use of eHealth technology for this purpose. Developing eHealth interventions specifically for populations at risk of long-term sick leave, and encouraging collaboration between all relevant stakeholders, may help improve work participation.

Sustained Attention and Working Memory Predict the Number of Days on Health-Related Benefits in the Year Following Occupational Rehabilitation.

Purpose The objective of this study was to investigate the association between cognitive and emotional functioning and the number of days on health-related benefits such as sick leave, work assessment allowance and disability pension. We investigated whether cognitive and emotional functioning at the start of rehabilitation and the change from the start to the end of rehabilitation predicted the number of days on health-related benefits in the year after occupational rehabilitation. Methods A sample of 317 individuals (age 19-67 years), mainly diagnosed with a musculoskeletal or mental and behavioural ICD-10 disorder, participated. The sample was stratified depending on the benefit status in the year before rehabilitation. Those receiving health-related benefits for the full year comprised the work assessment allowance and disability pension (WAA) group and those receiving benefits for less than a year comprised the sick leave (SL) group. The participants were administered cognitive and emotional computerised tests and work and health questionnaires at the beginning and end of rehabilitation. The cumulative number of days on health-related benefits during 12 months after rehabilitation was the primary outcome variable and age, gender, educational level, subjective health complaints, anxiety, and depression were controlled for in multiple regression analyses. Results The WAA group (n = 179) was significantly impaired at baseline compared to the SL group (n = 135) in focused attention and executive function, and they also scored worse on work and health related variables. Higher baseline scores and change scores from the start to the end of rehabilitation, for sustained attention, were associated with fewer number of health-related benefit days in the WAA group, while higher baseline scores for working memory were associated with fewer number of health-related benefit days in the SL group. Conclusions New knowledge about attention and memory and return to work in individuals with different benefit status may pave the way for more targeted programme interventions. Rehabilitation programmes could benefit from designing interventions that respectively improve sustain attention and working memory related to working life in individuals on sick leave or work assessment allowance and disability pension.

Independent medical evaluation of general practitioners' follow-up of sick-listed patients: a cross-sectional study in Norway.

OBJECTIVES: The study was designed to examine the sufficiency of general practitioners' (GPs) follow-up of patients on sick leave, assessed by independent medical evaluators. DESIGN: Cross-sectional study SETTING: Primary health care in the Western part of Norway. The study reuses data from a randomised controlled trial-the Norwegian independent medical evaluation trial (NIME trial). PARTICIPANTS: The intervention group in the NIME trial: Sick-listed workers having undergone an independent medical evaluation by an experienced GP at 6 months of unremitting sick leave (n=937; 57% women). In the current study, the participants were distributed into six exposure groups defined by gender and main sick leave diagnoses (women/musculoskeletal, men/musculoskeletal, women/mental, men/mental, women/all other diagnoses and men/all other diagnoses). OUTCOME MEASURE: The independent medical evaluators assessment (yes/no) of the sufficiency of the regular GPs follow-up of their sick-listed patients. RESULTS: Estimates from generalised linear models demonstrate a robust association between men with mental sick leave diagnoses and insufficient follow-up by their regular GP first 6 months of sick leave (adjusted relative risk (RR)=1.8, 95% CI=1.15-1.68). Compared with the reference group, women with musculoskeletal sick leave diagnoses, this was the only significant finding. Men with musculoskeletal diagnoses (adjusted RR=1.4, 95% CI=0.92-2.09); men with other diagnoses (adjusted RR=1.0, 95% CI=0.58-1.73); women with mental diagnoses (adjusted RR=1.2, 95% CI=0.75-1.77) and women with other diagnoses (adjusted RR=1.3, 95% CI=0.58-1.73). CONCLUSIONS: Assessment by an independent medical evaluator showed that men with mental sick leave diagnoses may be at risk of insufficient follow-up by their GP. Efforts should be made to clarify unmet needs to initiate relevant actions in healthcare and work life. Avoiding marginalisation in work life is of the utmost importance.

Occupational Rehabilitation Is Associated With Improvements in Cognitive Functioning.

INTRODUCTION: Occupational rehabilitation may be offered to workers on long-term sick leave who often report problems with cognitive functioning, anxiety, depression, pain, and reduced work ability. The empirical knowledge is sparce on how occupational rehabilitation may influence cognitive and emotional functioning and patients have not previously been subjected to comprehensive objective testing. The main aim of this study was to assess possible changes in cognitive and emotional functioning such as memory, attention, executive function, and emotion recognition among patients in occupational rehabilitation. METHODS: A large sample of 280 sick-listed workers referred to inpatient and outpatient occupational rehabilitation was recruited. The rehabilitation programs had a mean duration of 28 days and comprised physical activity, cognitive behavior treatment components and collaboration with the workplace. A pre-post design was applied to investigate possible changes in cognitive and emotional functioning (primary outcomes) and work and health measures (secondary outcomes), comparing the rehabilitation group with a control group of 70 healthy workers. Individuals in the control group were tested at random time points with an approximately 28 day interval between pre- and post-test, thus coinciding with the duration of rehabilitation. Repeated measures analysis of variance was used for the main analyses. RESULTS: Compared to the control group, the rehabilitation group had greater gains from pre- to post-test in focused and sustained attention, as well as greater improvements in work ability and reduction in subjective health complaints (SHC), helplessness, pain, pain related to work, anxiety, and depression. In the rehabilitation group, exploratory correlational analysis indicated that improvements in focused and sustained attention were associated with improvements in return-to-work self-efficacy, work ability as well as a reduction in SHC. CONCLUSION: The sick-listed workers improved in focused and sustained attention and work and health measures after participating in occupational rehabilitation. This study is one of the first to systematically investigate changes in cognitive and emotional functioning during occupational rehabilitation. Clinical practice should benefit from increased knowledge about all cognitive functions and should be specifically aware of the improvements in focused and sustained attention, while memory, executive function and emotion recognition remained unchanged. The results can be used as a motivation to tailor specific interventions to gain further improvements in all cognitive and emotional functions.

A quality indicator set for use in rehabilitation team care of people with rheumatic and musculoskeletal diseases; development and pilot testing.

BACKGROUND: Systems for monitoring effectiveness and quality of rehabilitation services across health care levels are needed. The purpose of this study was to develop and pilot test a quality indicator set for rehabilitation of rheumatic and musculoskeletal diseases. METHODS: The set was developed according to the Rand/UCLA Appropriateness Method, which integrates evidence review, in-person multidisciplinary expert panel meetings and repeated anonymous ratings for consensus building. The quality indicators were pilot-tested for overall face validity and feasibility in 15 specialist and 14 primary care rehabilitation units. Pass rates (percentages of "yes") of the indicators were recorded in telephone interviews with 29 unit managers (structure indicators), and 164 patients (process and outcome indicators). Time use and participants' numeric rating of face validity (0-10, 10 = high validity) were recorded. RESULTS: Nineteen structure, 12 process and five outcome indicators were developed and piloted. Mean (range) sum pass rates for the structure, process and outcome indicators were 59%(84%), 66%(100%) and 84%(100%), respectively. Mean (range) face validity score for managers/patients was 8.3 (8)/7.9 (9), and mean answering time was 6.0/5.5 min. The final indicator set consists of 19 structure, 11 process and three outcome indicators. CONCLUSION: To our knowledge this is the first quality indicator set developed for rehabilitation of rheumatic and musculoskeletal diseases. Good overall face validity and a feasible format indicate a set suitable for monitoring quality in rehabilitation. The variation in pass rates between centers indicates a potential for quality improvement in rheumatic and musculoskeletal rehabilitation in Norway.

eHealth interventions to facilitate work participation: a scoping review protocol.

REVIEW QUESTION: The objective of this scoping review is to identify and synthesize existing literature on the different types of eHealth interventions used in workplaces and healthcare settings to facilitate work participation. The following questions will be examined: For which user groups, in which settings and by which stakeholders are eHealth interventions provided? Are eHealth interventions that are aimed at work participation theory-driven or based on empirical evidence?

Independent medical evaluation for sick-listed workers in Norway: A focus group study of the experience of IME doctors.

BACKGROUND: Norwegian politicians have proposed the use of an independent medical evaluation (IME) as a possible solution for reducing long-term sick leave. The use of an IME implies that a new doctor interferes in the relationship between sick-listed workers and their general practitioner (GP). The aim of the current study was to explore experiences of IME doctors from an ongoing randomized controlled trial (the NIME trial evaluating the effect of IME in Norway). METHODS: Two focus group interviews were conducted with eight of the nine IME doctors employed in the NIME trial. The discussions were audio-taped and transcribed. Systematic text condensation was used for analysis. RESULTS: The participants reported that the IME provides important second opinions, which they felt empowered the sick-listed workers and provided new insights into their condition. Beneficial IME working conditions and enhanced insight into different sick leave measures were crucial to this perceived usefulness. Some of the participants expressed disappointment with GPs acting as passive conductors and struggled to provide feedback politely. Some adjustments were proposed as necessary for the IME to be implemented nationwide. CONCLUSIONS: The participants seemed to have gained a different stakeholder identity by sometimes seeing GPs, their peers, as obstacles to return to work and welcomed the use of IME on a regular basis.

Cross-cultural adaptation of the Work Role Functioning Questionnaire 2.0 to Norwegian and Danish.

BACKGROUND: A healthy and productive working life has attracted attention owing to future employment and demographic challenges. OBJECTIVE: The aim was to translate and adapt the Work Role Functioning Questionnaire (WRFQ) 2.0 to Norwegian and Danish. METHODS: The WRFQ is a self-administered tool developed to identify health-related work limitations. Standardised cross-cultural adaptation procedures were followed in both countries' translation processes. Direct translation, synthesis, back translation and consolidation were carried out successfully. RESULTS: A pre-test among 78 employees who had returned to work after sickness absence found idiomatic issues requiring reformulation in the instructions, four items in the Norwegian version, and three items in the Danish version, respectively. In the final versions, seven items were adjusted in each country. Psychometric properties were analysed for the Norwegian sample (n = 40) and preliminary Cronbach's alpha coefficients were satisfactory. A final consensus process was performed to achieve similar titles and introductions. CONCLUSIONS: The WRFQ 2.0 cross-cultural adaptation to Norwegian and Danish was performed and consensus was obtained. Future validation studies will examine validity, reliability, responsiveness and differential item response. The WRFQ can be used to elucidate both individual and work environmental factors leading to a more holistic approach in work rehabilitation.

Protocol for the effect evaluation of independent medical evaluation after six months sick leave: a randomized controlled trial of independent medical evaluation versus treatment as usual in Norway.

BACKGROUND: It has been discussed whether the relationship between a patient on sick leave and his/her general practitioner (GP) is too close, as this may hinder the GP's objective evaluation of need for sick leave. Independent medical evaluation involves an independent physician consulting the patient. This could lead to new perspectives on sick leave and how to follow-up the patient. METHODS/DESIGN: The current study is a randomized controlled trial in a Norwegian primary care context, involving an effect evaluation, a cost/benefit analysis, and a qualitative evaluation. Independent medical evaluation will be compared to treatment as usual, i.e., the physicians' and social insurance agencies' current management of long-term sick-listed patients. Individuals aged 18-65 years, sick listed by their GP and on full or partial sick leave for the past 6 months in Hordaland county will be included. Exclusion criteria are pregnancy, cancer, dementia or an ICD-10 diagnosis. A total sample of 3800 will be randomly assigned to either independent medical evaluation or treatment as usual. Official register data will be used to measure the primary outcome; change in sickness benefits at 7, 9 and 12 months. Sick listed in other counties will serve as a second control group, if appropriate under the "common trend" assumption. DISCUSSION: The Norwegian effect evaluation of independent medical evaluation after 6 months sick leave is a large randomized controlled trial, and the first of its kind, to evaluate this type of intervention as a means of getting people back to work after long-term sickness absence. TRIAL REGISTRATION: ClinicalTrials.gov NCT02524392 . Registered June 23, 2015.

Subjective health complaints, functional ability, fear avoidance beliefs, and days on sickness benefits after work rehabilitation - a mediation model.

BACKGROUND: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

Changes in cognitive functioning in sick-listed participants in occupational rehabilitation: A feasibility study.

BACKGROUND: Individuals on long-term sick leave attending occupational rehabilitation often complain about impairments in cognitive functions such as memory and attention. Knowledge of cognitive functioning in these individuals is limited. Such knowledge is clinically relevant for improving occupational rehabilitation programmes. OBJECTIVE: The aims of this feasibility study were to assess the methodological design and to investigate changes in memory and attention on participants during occupational rehabilitation. METHODS: Individuals attending occupational rehabilitation (n = 28) and individuals working full time (n = 25) matched for age, gender, and education participated. The two groups were administered cognitive tests targeting memory and attention and self-reported questionnaires at pre-test and post-test. Outcome measures were speed and accuracy of responses on the cognitive tests and self-reported work ability, subjective health complaints, and symptoms of depression and anxiety. RESULTS: In total, 35% of all invited participants agreed to take part and 93% of these also completed the second test. The mean gain scores in the intervention group were significantly higher than in the control group in response latency on simple and choice reaction time and errors in spatial working memory. CONCLUSION: The results of this study indicate that the motivation of participants to complete testing was high. Improvements in memory and attention were evident in rehabilitation participants indicating that rehabilitation may have an effect on cognitive functions.

Causal inference in multi-state models-sickness absence and work for 1145 participants after work rehabilitation.

BACKGROUND: Multi-state models, as an extension of traditional models in survival analysis, have proved to be a flexible framework for analysing the transitions between various states of sickness absence and work over time. In this paper we study a cohort of work rehabilitation participants and analyse their subsequent sickness absence using Norwegian registry data on sickness benefits. Our aim is to study how detailed individual covariate information from questionnaires explain differences in sickness absence and work, and to use methods from causal inference to assess the effect of interventions to reduce sickness absence. Examples of the latter are to evaluate the use of partial versus full time sick leave and to estimate the effect of a cooperation agreement on a more inclusive working life. METHODS: Covariate adjusted transition intensities are estimated using Cox proportional hazards and Aalen additive hazards models, while the effect of interventions are assessed using methods of inverse probability weighting and G-computation. RESULTS: Results from covariate adjusted analyses show great differences in sickness absence and work for patients with assumed high risk and low risk covariate characteristics, for example based on age, type of work, income, health score and type of diagnosis. Causal analyses show small effects of partial versus full time sick leave and a positive effect of having a cooperation agreement, with about 5 percent points higher probability of returning to work. CONCLUSIONS: Detailed covariate information is important for explaining transitions between different states of sickness absence and work, also for patient specific cohorts. Methods for causal inference can provide the needed tools for going from covariate specific estimates to population average effects in multi-state models, and identify causal parameters with a straightforward interpretation based on interventions.

Functioning, coping and work status three years after participating in an interdisciplinary, occupational rehabilitation program.

AIM: The aim of this study was to explore how functional ability, coping and health were related to work and benefit status three years after participating in a four-week inpatient interdisciplinary occupational rehabilitation program. METHODS: The cohort consisted of 338 individuals (75% females, mean age 51 years (SD=8.6)) who three years earlier had participated in a comprehensive inpatient interdisciplinary occupational rehabilitation program, due to long-term sick leave. The participants answered standardised questionnaires about subjective health complaints, functional ability, coping, and current work and benefit status. The relationships between these variables were analysed using logistic regression analyses. RESULTS: At the time of the survey, 59% of the participants worked at least 50% of a full working day. Twenty-five percent received at least 50% disability pension and 16% received other benefits. Poor functional ability (OR 4.8; CI 3.0-7.6), poor general health (OR 3.8; CI 2.3-6.1), high level of subjective health complaints (OR 3.3; CI 2.1-5.2), low coping (OR 2.8; CI 1.7-4.4), poor physical fitness (OR 2.8; CI 1.7-4.6) and poor sleep quality (OR 2.4; CI 1.5-3.7) were associated with receiving allowances. In a fully adjusted model, only poor functional ability and low coping were associated with receiving allowances three years after occupational rehabilitation. CONCLUSIONS: Functional ability and coping were the variables most strongly associated with not having returned to work. More attention should therefore be paid to enhance these factors in occupational rehabilitation programs. Part-time work may be a feasible way to integrate individuals with reduced workability in working life, if the alternative is complete absence from work.

Prognostic factors for return to work, sickness benefits, and transitions between these states: a 4-year follow-up after work-related rehabilitation.

PURPOSE: The aim of this study was to examine if age, gender, medical diagnosis, occupation, and previous sick leave predicted different probabilities for being at work and for registered sickness benefits, and differences in the transitions between any of these states, for individuals that had participated in an interdisciplinary work-related rehabilitation program. METHODS: 584 individuals on long-term sickness benefits (mean 9.3 months, SD = 3.4) were followed with official register data over a 4-year period after a rehabilitation program. 66 % were female, and mean age was 44 years (SD = 9.3). The majority had a mental (47 %) or a musculoskeletal (46 %) diagnosis. 7 % had other diagnoses. Proportional hazards regression models were used to analyze prognostic factors for the probability of being on, and the intensity of transitions between, any of the following seven states during follow-up; working, partial sick leave, full sick leave, medical rehabilitation, vocational rehabilitation, partial disability pension (DP), and full DP. RESULTS: In a fully adjusted model; women, those with diagnoses other than mental and musculoskeletal, blue-collar workers, and those with previous long-term sick leave, had a lower probability for being at work and a higher probability for full DP during follow-up. DP was also associated with high age. Mental diagnoses gave higher probability for being on full sick leave, but not for transitions to full sick leave. Regression models based on transition intensities showed that risk factors for entering a given state (work or receiving sickness benefits) were slightly different from risk factors for leaving the same state. CONCLUSIONS: The probabilities for working and for receiving sickness benefits and DP were dependent on gender, diagnoses, type of work and previous history of sick leave, as expected. The use of novel statistical methods to analyze factors predicting transition intensities have improved our understanding of how the processes to and from work, and to and from sickness benefits may differ between groups. Further research is required to understand more about differences in prognosis for return to work after intensive work-related rehabilitation efforts.

Multiple transitions in sick leave, disability benefits, and return to work. - A 4-year follow-up of patients participating in a work-related rehabilitation program.

BACKGROUND: Return to work (RTW) after long-term sick leave can be a long-lasting process where the individual may shift between work and receiving different social security benefits, as well as between part-time and full-time work. This is a challenge in the assessment of RTW outcomes after rehabilitation interventions. The aim of this study was to analyse the probability for RTW, and the probabilities of transitions between different benefits during a 4-year follow-up, after participating in a work-related rehabilitation program. METHODS: The sample consisted of 584 patients (66% females), mean age 44 years (sd = 9.3). Mean duration on various types of sick leave benefits at entry to the rehabilitation program was 9.3 months (sd = 3.4)]. The patients had mental (47%), musculoskeletal (46%), or other diagnoses (7%). Official national register data over a 4-year follow-up period was analysed. Extended statistical tools for multistate models were used to calculate transition probabilities between the following eight states; working, partial sick leave, full-time sick leave, medical rehabilitation, vocational rehabilitation, and disability pension; (partial, permanent and time-limited). RESULTS: During the follow-up there was an increased probability for working, a decreased probability for being on sick leave, and an increased probability for being on disability pension. The probability of RTW was not related to the work and benefit status at departure from the rehabilitation clinic. The patients had an average of 3.7 (range 0-18) transitions between work and the different benefits. CONCLUSIONS: The process of RTW or of receiving disability pension was complex, and may take several years, with multiple transitions between work and different benefits. Access to reliable register data and the use of a multistate RTW model, makes it possible to describe the developmental nature and the different levels of the recovery and disability process.
