Purpose: People with a work disability pension receive vocational rehabilitation (VR) services from the Dutch Social Security Institute (SSI) in order to facilitate return-to-work (RTW). The SSI offers tailored VR existing of two trajectories (aimed at getting fit for work or aimed at returning to work). The purpose of this study is to describe the current practice of VR. This includes a description of client characteristics, RTW barriers and the intensity, duration, content and the outcomes of the offered trajectories., Materials and Methods: We analyzed data from 197 clients that were randomly selected from clients who attended a VR trajectory between 1 January t 2017 and 31 December 2018. Data were obtained from the SSI registration databases and client files., Results: Both VR trajectories at the SSI have a different aim, but in practice the content of the VR interventions often overlaps. Around half of both trajectories reached their goal. Reasons for unsuccessful trajectories were that the client did not find work or barriers were more complex than initially assessed., Conclusions: The SSI delivers tailored VR to the specific needs of the client, however substantiations for why a certain VR intervention is offered are limited. Guidelines are needed to support professionals.

Purpose: This feasibility study focusses on the implementation and use of a decision aid, which supports vocational rehabilitation (VR) professionals in helping clients with a disability pension return to work in practice. The decision aid shows an overview of the clients' return to work barriers and suggests suitable VR interventions based on these barriers., Methods: The study population consisted of VR professionals working at the Dutch Social Security Institute and their clients receiving a (partial) work disability pension. The feasibility was measured with concepts of the Linnan and Steckler framework and the attitude, social norm and self-efficacy model. Data were collected using questionnaires, checklists and qualitative interviews., Results: Ten professionals participated in this study. Fifty-four clients were asked to fill in the questionnaire of the decision aid and 32 clients received VR care based on the decision aid. In general, VR professionals and clients were satisfied with the decision aid and perceived a few barriers for using the decision aid., Conclusions: This study showed that it is feasible to implement and use the decision aid. To improve the implementation of this decision aid, it should be implemented in digital systems used by professionals to improve efficiency of working with the decision aid., (© 2023.

Background: The consequences of restrictive measures during the COVID-19 outbreak have potentially been enormous, especially for those in a vulnerable position in the labour market. This study aims to describe the impact of the COVID-19 crisis on work status, working conditions and health among people with (partial) work disabilities-with and in search of work-during the COVID-19 pandemic in the Netherlands., Methods: A mixed methods design was used, combining a cross-sectional online survey and ten semi-structured interviews with people with a (partial) work disability. The quantitative data included responses to job-related questions, self-reported health, and demographics. The qualitative data consisted of participants' perceptions about work, vocational rehabilitation, and health. We used descriptive statistics to summarize the responses, conducted logistic and linear regression and integrated our qualitative findings with the quantitative findings, aiming at complementarity., Results: Five hundred and eighty-four participants (response rate 30.2%) completed the online survey. The majority of participants experienced no change in work status: 39 percent remained employed, 45 percent remained unemployed, six percent of respondents lost their job, and ten percent became employed during the COVID-19 crisis. In general, the results showed a deterioration in self-rated health during the COVID-19 outbreak, both for participants at work and in search of work. Participants who lost their job during the COVID-19 crisis reported the highest deterioration in self-rated health. Interview findings revealed that loneliness and social isolation were persistent during the COVID-19 crisis, especially among those in search of work. Additionally, employed participants identified a safe work environment and the possibility to work at the office as important factors for overall health., Conclusions: The vast majority of study participants (84.2%) experienced no change in work status during the COVID-19 crisis. Nonetheless, people at work and in search of work encountered barriers to maintaining or (re)gaining employment. People with a (partial) work disability who lost their job during the crisis appeared to be most affected in terms of health. Employment and health protections could be strengthened for persons with (partial) work disabilities in order to build resilience in times of crisis., (© 2023. The Author(s).)

Background: Long-term disability has a great impact on both society and workers with disabilities. Little is known about the barriers which prohibit workers with long-term disabilities from returning to work and which interventions are best suited to counteract these barriers. The main purpose of this study was to obtain consensus among professionals on important return to work (RTW) factors and effective vocational rehabilitation (VR) interventions for long-term (> 2 years), partially disabled workers. Our three research questions were: (1) which factors are associated with RTW for long-term disabled workers?; (2) which factors associated with RTW can be targeted by VR interventions?; and (3) which VR interventions are the most effective to target these factors?, Methods: A modified Delphi Study was conducted using a panel of 22 labour experts, caseworkers, and insurance physicians. The study consisted of several rounds of questionnaires and one online meeting., Results: The multidisciplinary panel reached consensus that 58 out of 67 factors were important for RTW and that 35 of these factors could be targeted using VR interventions. In five rounds, the expert panel reached consensus that 11 out of 22 VR interventions were effective for at least one of the eight most important RTW factors., Conclusions: Consensus was reached among the expert panel that many factors that are important for the RTW of short-term disabled workers are also important for the RTW of long-term partially disabled workers and that a substantial number of these factors could effectively be targeted using VR interventions. The results of this study will be used to develop a decision aid that supports vocational rehabilitation professionals in profiling clients and in choosing suitable VR interventions., (© 2022.

Purpose Assessment of prognosis of work disability is a challenging task for occupational health professionals. An evidence-based decision support tool, based on a prediction model, could aid professionals in the decision-making process. This study aimed to evaluate the efficacy of such a tool on Dutch insurance physicians' (IPs) prognosis of work ability and their prognostic confidence, and assess IPs' attitudes towards use of the tool. Methods We conducted an experimental study including six case vignettes among 29 IPs. For each vignette, IPs first specified their own prognosis of future work ability and prognostic confidence. Next, IPs were informed about the outcome of the prediction model and asked whether this changed their initial prognosis and prognostic confidence. Finally, respondents reported their attitude towards use of the tool in real practice. Results The concordance between IPs' prognosis and the outcome of the prediction model was low: IPs' prognosis was more positive in 72 (41%) and more negative in 20 (11%) cases. Using the decision support tool, IPs changed their prognosis in only 13% of the cases. IPs prognostic confidence decreased when prognosis was discordant, and remained unchanged when it was concordant. Concerning attitudes towards use, the wish to know more about the tool was considered as the main barrier. Conclusion The efficacy of the tool on IPs' prognosis of work ability and their prognostic confidence was low. Although the perceived barriers were overall limited, only a minority of the IPs indicated that they would be willing to use the tool in practice.

Objectives Weighted regression procedures can be an efficient solution for cohort studies that involve rare events or diseases, which can be difficult to predict, allowing for more accurate prediction of cases of interest. The aims of this study were to (i) predict changes in work ability at one year after approval of the work disability benefit and (ii) explore whether weighted regression procedures could improve the accuracy of predicting claimants with the highest probability of experiencing a relevant change in work ability. Methods The study population consisted of 944 individuals who were granted a work disability benefit. Self-reported questionnaire data measured at baseline were linked with administrative data from Dutch Social Security Institute databases. Standard and weighted multinomial logit models were fitted to predict changes in the work ability score (WAS) at one-year follow-up. McNemar's test was used to assess the difference between these models. Results A total of 208 (22%) claimants experienced an improvement in WAS. The standard multinomial logit model predicted a relevant improvement in WAS for only 9% of the claimants [positive predictive value (PPV) 62%]. The weighted model predicted significantly more cases, 14% (PPV 63%). Predictive variables were several physical and mental functioning factors, work status, wage loss, and WAS at baseline. Conclusion This study showed that there are indications that weighted regression procedures can correctly identify more individuals who experience a relevant change in WAS compared to standard multinomial logit models. Our findings suggest that weighted analysis could be an effective method in epidemiology when predicting rare events or diseases.

Background: Today, work disability is one of the greatest social and labour market challenges for policy makers in most OECD countries, where on average, about 6% of the working-age population relies on disability benefits. Understanding of factors associated with long-term work disability may be helpful to identify groups of individuals at risk for disability benefit entitlement or continuing eligibility, and to develop effective interventions for these groups. The purpose of this study is to provide insight into the main diagnoses of workers who qualify for disability benefits and how these diagnoses differ in age, gender and education. Using a five-year follow-up, we examined the duration of disability benefits and how durations differ among individuals with various characteristics., Methods: We performed a cohort study of 31,733 individuals receiving disability benefits from the Dutch Social Security Institute (SSI) with a five-year follow-up. Data were collected from SSI databases. Information about disorders was assessed by an insurance physician upon benefit application. These data were used to test for significant relationships among socio-demographics, main diagnoses and comorbidity, and disability benefit entitlement and continuing eligibility., Results: Mental disorders were the most frequent diagnosis for individuals claiming work disability. Diagnoses differed among age groups and education categories. Mental disorders were the main diagnosis for work disability for younger and more highly educated individuals, and physical disorders (generally musculoskeletal, cardiovascular and cancer) were the main diagnosis for older and less educated individuals. In 82% of the claims, the duration of disability benefit was five years or more after approval. Outflow was lowest for individuals with (multiple) mental disorders and those with comorbidity of mental and physical disorders, and highest for individuals with (multiple) physical disorders., Conclusions: The main diagnosis for persons entitled to disability benefits was mental health problems, especially for young women. In a five-year follow-up, claim duration for disability benefits was long lasting for most claimants.
