Lage rugklachten zijn een groot probleem in de Westerse samenleving. Zij kunnen ziekteverzuim en arbeidsongeschiktheid veroorzaken en als gevolg daarvan grote kosten met zich meebrengen. Bedrijfsartsen adviseren vaak werkaanpassingen en oefenprogramma's om de werkhervatting van werknemers met lage rugklachten te bevorderen, maar er is weinig wetenschappelijk bewijs dat dit effectief is. Dit proefschrift besteedt, naar analogie van Canadees onderzoek, aandacht aan de effectiviteit van een methode voor werkaanpassing met actieve betrokkenheid van werknemer en werkgever en de effectiviteit van een fysiotherapeutisch oefenprogramma. De methode voor werkaanpassing blijkt werkhervatting te bespoedigen, hetgeen zowel gezondheidkundige als economische winst oplevert. Het fysiotherapeutische oefenprogramma blijkt in dit onderzoek geen meerwaarde te hebben. Verder is in dit proefschrift gekeken naar de oorzaken van een vertraging in de terugkeer naar werk.

We hypothesized that different factors affect the duration of the leave depending on the time away from work. Methods The review occurred in seven phases: (1) developing the central question, (2) conducting the literature search, (3) identifying relevant publications, (4) quality appraisal, (5) data extraction, (6) evidence synthesis, and (7) knowledge translation. We searched for studies that reported episodes of LBP and sick leave that lasted more than 6 weeks. All included studies reported at least one prognostic factor where return to work was the outcome. Results We identified twenty-two relevant publications. The impact of pain, functional status and radiating pain seems to change with duration of work disability. Workers' recovery expectations remain important after 6 weeks. Modified duties are rarely studied in later phases of work disability. Depression/mental health did not appear to be an important factor in later phases. Workplace physical factors remain important. There is insufficient evidence that pain catastrophising and fear avoidance are predictive factors in later phases. There was moderate evidence for age in the later phases. Functional capacity and claim related factors were supported by some evidence. Discusion Physical demands in the workplace are preventing workers from getting back to work in a timely fashion across phases. The psychosocial work environment is understudied in later phases. Overall, we cannot conclude that prognostic factors change over time.

The objective of this review is to determine the factors that predict RTW from the sub-acute and chronic stage of a low back pain related episode of time away from work. The current review is an expansion of a review published in 2005 that examined the acute stage. Methods A search of PubMed, EMBASE and PsycINFO from inception to February 2012 was conducted. Retrieved references will be screened for relevancy independently by two reviewers and when consensus cannot be reached a third reviewer will be consulted. Reviewers will not assess articles they are an author on. Quality appraisal and data extraction forms developed by the research team will be used. Analysis of the results will involve Levels of Evidence and, if possible, results will be pooled. Results Of the 5027 references that were retrieved 117 relevant prognosis studies and 72 relevant intervention studies were found. Prognosis studies will be used to identify prognostic factors for RTW and intervention studies will be referred to in final reports as possible ways to address identified prognostic factors. The findings from this review will be used to create a handbook for clinicians involved in the RTW process and will be shared in four different workshops to various stakeholder groups. Conclusions This review will provide insight into the factors that affect RTW among individuals at the sub-acute and chronic stages of time away from work due to low back pain.

Results showed satisfaction with both the questionnaire and the decision rules among the professionals. Also, points of improvement were identified. Conclusion This study indicates feasibility of the proposed triage tool, to effectively determine the necessary intensity of occupational health care interventions for sick-listed workers without an employment contract. To overcome important barriers and construct an optimal triage model, attention should be paid to further improve the questionnaire and decision rules.

Methods A dynamic cohort composed of all permanent civil servants hired from 2005 to 2011 by the Goiania municipality, in Brazil. Records of medically certified SA longer than three days were provided by the municipality. Incidence density (ID) was calculated per 1,000 person-years in each ICD-10 category. The costs were calculated by summing the benefits paid for work days lost during the follow up time. Results 18,450 workers, median age of 32 years, accumulated 14,909 SA episodes totaling 323,646 work days lost. The total cost of sickness absence was 8,963,217,592USD.ThemeanSAepisodewas22days,andthemeancostwas8,963,217,592 USD. The mean SA episode was 22 days, and the mean cost was 8,963,217,592USD.ThemeanSAepisodewas22days,andthemeancostwas601.1/episode. Overall the ID was 228.8 episodes per 1,000 person-years. Diagnostic groups with the highest SA ID were injuries (48.3 per 1,000 person-years), musculoskeletal diseases (31.0 per 1,000 person-years) and mental disorders (28.1 per 1,000 person-years). Highest episode costs were associated with mental disorder and injuries, and the lowest costs were for infectious diseases. Major cost peaks were observed among females (71.4%), aged 25 to 34 years (41.4%), married (51.2%), with high education (54.9%) and highest income (59.6%), among health professionals (30.9%), with multiple jobs (63.3%) and working part time (55.6%). Conclusions This study showed a substantial economic burden of SA among Brazilian newly employed workers. Our findings suggest the need of the implementation of preventive actions target to new workers, such as proper training, reduction of work-related stress, adequate supervisor support, and the surveillance of early symptoms.

An important demographic trend that will affect worker health and work disability is aging of the workforce. While the number of aging workers wanting or needing to return to work or stay at work after injury or chronic disease is increasing, knowledge on their specific needs and circumstances has not been summarized in a systematic way. The increasing aging working population will necessitate an understanding of efforts to prevent work disability among aging workers. Therefore, we have undertaken a review to synthesize the evidence on the effectiveness of interventions aimed at preventing poor outcome in aging workers and synthesize the literature on what determines risk of poor outcome in aging workers.
