Plain English Summary
Background and study aims
Musculoskeletal disorders and common mental disorders are the main reasons for long-term sickness absence and disability. Many of these conditions have no or few medical explanations, and many patients are suffering from two or more disorders/ailments at the same time (co-morbidity). The main aim of occupational rehabilitation programs is to help people with such disabilities to return to work (RTW). However, knowledge regarding how well these programs work is very limited, and we know even less about which programs are best suited for which patients.
In this study, we want to compare the performance of two occupational rehabilitation programs in Norway. The main outcome is stable return to work. We will also examine if some groups of patients will benefit more from the one or the other program, and if there are any differences in costs to society in general. Several secondary outcomes will also be evaluated.
We will use a combination of methods in our data collection and analysis in order to increase our understanding of some of the mechanisms through which occupational rehabilitation programs might bring about change that support RTW. What may hinder or promote RTW among the participants during and after the occupational rehabilitation program?
The specific aims of the study are to evaluate the effectiveness of two occupational rehabilitation programs in Norway with regard to any differences in:
1. Stable return to work (work for a minimum of 4 weeks after return to work) (main outcome)
2. Sub-groups of patients that benefit more from a specific type of intervention, e.g. differences by gender, age, education, health complexity
3 The participants’ trajectories in and out of work during a 5-year follow-up
4. Cost-effectiveness/utility/benefit
5. The participants’ experienced quality of life
6. The participants’ experienced health and work ability
7. The participants’ experienced readiness for return to work
8. The participants’ experienced return to work self-efficacy
9. The participants’ experienced return to work fear avoidance
10. To compare return to work outcomes for the clinics with the results of a group drawn from the register of the Norwegian Labor and Welfare Service
By use of process evaluation, we will investigate possible underlying mechanisms pertaining to inpatient and outpatient occupational rehabilitation program outcomes. Our aim is also to explain barriers and facilitators for a return to work as program providers, key stakeholders and users experience them.
Who can participate?
Employed or self-employed adults aged 18-55 who are referred to occupational rehabilitation by a physician because of musculoskeletal disorders and/or common mental health disorders, such as stress, anxiety, and depression. In addition, they must have been sick-listed for a minimum of six weeks last year.
What does the study involve?
In the first part of the study, 2014-2018, participants are randomly allocated into one of two groups. Those in group 1 receive treatment in an outpatient occupational rehabilitation clinic at Sykehuset Telemark in Porsgrunn. Those in group 2 receive treatment in an inpatient occupational rehabilitation clinic in Rauland.
In the second part of the study, 2018-2021, the participants get their treatment at the clinic they are referred to by their general practitioners without randomisation.
The programs at both clinics are comprehensive and are provided by interdisciplinary teams. The teams consist of a physician, a physiotherapist, a psychologist or a specialized nurse, and an occupational counselor/work consultant. The inpatient intervention has, in addition, a physical education teacher, a nutrition counselor, a riding instructor, and a recreation instructor.
The span of the inpatient intervention is four weeks. Each week is approximately 35 hours. The span of the outpatient intervention is three months, but the number of days and hours per week varies according to the need of the participant.
Both clinics use cognitive, behavioral, and educational approaches to increase the participants’ abilities and readiness for returning to work. Interaction with relevant stakeholders is part of the rehabilitation process (e.g. the participant’s employer, general practitioner, family, or NAV-consultant). The inpatient intervention is more group-based and intensive than the outpatient intervention. The outpatient intervention, on the other hand, is more individually tailored and has closer collaboration with the workplace. If the participants need follow-up after the program, the clinics collaborate with local services.
What are the possible benefits and risks of participating?
There are no risks involved in participating in the study. The participants will get a comprehensive occupational rehabilitation service whether they get the inpatient or outpatient intervention. We are not able to tell whether they would benefit more from the one or the other intervention.

| Scientific title | Comparing effects of two interdisciplinary occupational rehabilitation programs for people with musculoskeletal disorders, common mental disorders, or both: a nonrandomized clinical trial with a concurrent process evaluation |
| Study acronym | STAiR |
| Study hypothesis | Added 06/03/2019: Several earlier studies have shown that complex occupational rehabilitation programs are more effective in helping people returning to work than single interventions. However, since we compare two complex programs in this study, we do not expect to find any overall differences in return to work between the programs. We do expect that there might be some groups of patients that will benefit more from the one or the other program.

Return to work fear avoidance, Fear-Avoidance Belief Questionnaire Survey data collected at baseline, 4 weeks, 3, 6, 12 and 24 months. The participants are followed with register data until 5 years after inclusion in the project. Added 07/03/2019: Non-randomised groups: Survey data are collected at baseline, end of program and at 6 and 12 months. Only SF-6D and WAI are used at 6 and 12 months. 7. The themes from 1.2 to 1.6 are also covered in interviews with participants. They are also interviewed regarding their expectations and evaluation of the rehabilitation program they have participated in; collaboration between key stakeholders in their RTW process; and their experiences of barriers and facilitators in their RTW process. The participants are interviewed at baseline, end of the intervention, and about 6 and 12 months after inclusion in the project. |
