Enhancement of Quality of Work And Life

Work participation is essential for quality of life, providing purpose, social interaction, financial security, and shaping social status. Work participation is increasingly compromised in people with slowly progressive chronic disorders (hereafter referred to as progressive disorders). This negatively impacts their quality of life. Early work-related support, focused on sustainable work-retention, has the potential to enhance work participation in people with progressive disorders. Therefore, this study investigates the (cost)effectiveness of the Preventive Participatory Workplace Intervention (PPWI), a personalized work intervention to enhance sustainable work participation. The investigators perform an 18-month randomized controlled trial (RCT). In addition, the investigators perform a process evaluation and an economic evaluation alongside the RCT. 124 Dutch working persons with three types of movement disorders will be included: Parkinson's Disease (PD), cerebellar ataxia (CA) and hereditary spastic paraparesis (HSP) and with slowly progressive neuromuscular and mitochondrial disorders.

Work participation is essential for quality of life, providing purpose, social interaction, financial security, and shaping social status and personal identity. Work participation is increasingly compromised in people with progressive disorders. This negatively impacts their quality of life. People with slowly progressive chronic disorders (hereafter referred to as progressive disorders) lack (structural) work-related support. Early work-related support, focused on sustainable work-retention, has the potential to enhance work participation in people with progressive disorders. Therefore, the EQuAL-study (Enhancement of Quality of work And Life) investigates the (cost)effectiveness of the Preventive Participatory Workplace Intervention (PPWI), a personalized intervention to enhance sustainable work participation in people with progressive disorders. The aim of the study is to investigate study effects of the PPWI on need for recovery after work (primary endpoint), perceived self-efficacy at work, work-related well-being, quality of life and absenteeism (secondary outcomes). In addition, the PPWI's cost-effectiveness and cost-utility and its the process of implementation and mechanisms of impact will be explored (second and third aim, respectively). To address these aims, the investigators perform an 18 month randomized controlled trial (RCT). A cost and process evaluation will be performed alongside the RCT. 124 Dutch working persons with types of movement disorders will be included: Parkinson's Disease (PD), cerebellar ataxia (CA), and hereditary spastic paraparesis (HSP) and with slowly progressive neuromuscular and mitochondrial disorders. Participants will be recruited from approximately twelve regions across the Netherlands. Participants will be randomised to either the PPWI or an usual care control group in a 1:1 ratio. The PPWI is a process intervention in which a trained process facilitator guides an employee and their manager in identifying work-related obstacles or changes and finding solutions to overcome or manage these obstacles. Its primary goal is to achieve consensus between employee and manager with respect to the most obstructive obstacles for functioning at work and feasible solutions. There are no restrictions on usual care. The study will evaluate between-group differences from baseline to 18-month follow-up in need for recovery after work (primary endpoint) and self-efficacy at work and indicators of quality of life, work-related well-being, and productivity (i.e. absenteeism and presenteeism). For the second aim, the investigators will measure the costs associated with healthcare use, productivity loss, work-related adjustments, and the intervention. For the third aim, the investigators will evaluate the process in terms of implementation of the PPWI, its mechanisms of impact and the implementation context. The investigators envision the PPWI to support sustainable work retention while preserving work-life balance and quality of life for individuals with progressive disorders. Additionally, the trial will provide insights into which intervention components are effective and why. This will help potential future PPWI users in making informed decisions about whether the costs are justified by the anticipated value and benefits.
