Brief Summary

In Sweden mental disorders have the highest proportion of sickness absence and sickness spells. One cause for this is proposed as the lack of knowledge on which activity limitations that have an impact on the ability to return to work. Further, there is a knowledge gap concerning the effect of which early measures from the health system, assessments and early rehabilitation interventions, that enables return to work. Such early measures have been proposed to have a more multidimensional perspective, than to solely focus on specific tasks during a work situation.

The aim of the current project is to examine the effect of an early assessment of activity limitations, made by occupational therapists within specialized psychiatric care, at the time for the next prolonged sickness certification. The assessment will be included in the sickness certificate, and results will be compared between the intervention group and a control group. The results are calculated for differences on treatment measures, prevalence of questions from the Social Insurance Agency and changes in the patterns for sick leave spells. Further, the prevalence of activity limitations and the sick listed participants assessments of the effect of the intervention will be presented.

The results are expected to lead to more adequate interventions for the individual regarding support to return to work, better routines for assessment and rehabilitation within the health care system, which in turn can facilitate decisions for sickness benefits and further have an impact on the long sick leave spells concerning mental disorders.

Detailed Description

Several individuals diagnosed with mental health disorders get sick-listed, and further, stay within the sick-leave process for a prolonged period. More research has been warranted both concerning how to assess activity limitations and future work capacity when having a psychiatric diagnose, but also when it comes to find suitable measures for supporting individuals to return to work. Such supportive and rehabilitative measures could be situated within the healthcare system, such as specialized psychiatric care. To conduct these measures, both early assessments as well as investigation of the effect of taken measures are needed. The present study concerns an expanded assessment of activity limitations as a basis for possible interventions with a focus on the individuals sick-leave process.

The understanding of work capacity has been proposed as a complex phenomenon, where several perspectives are needed. The contribution from occupational therapist in the teamwork implies being focussed on activity limitations or facilitators in contrast to solely focussing on body functions or symptoms. In the professional vocabular, activities are named occupations, meaning that the actual performance is influenced both by individual experiences and influenced by factors in the environment. Another assumption is that all everyday life occupations are interacting, and thus could have an impact on work capacity.

The purpose with this randomized, controlled trial is to evaluate if an early and expanded assessment made by occupational therapist, and with the use of two validated instruments A Dialogue About Ability Related to Work (DOA) and Satisfaction with Daily Occupations (SDO), can have an impact on choice of interventions, changes in the patterns for sick leave spells as well as prevalence of questions from the Social Insurance Agency (SIA) and the participators evaluation of effects from being part of the project. The chosen instruments are described as complementing each other, where DOA examines an overall summary of prerequisites for work capacity, and SDO adds a broader understanding of a person's occupations in everyday life, including satisfaction and balance between different occupational arenas such as work, un-paid work, leisure etc.

The project will be carried out in specialized, psychiatric teams within the Region Västra Götaland. The aim is to recruit 150 participants (75 to the intervention group and 75 to the control group). The participants will be randomly and consecutively divided into intervention or control group. Inclusion criteria are all patients registered at the chosen psychiatric care centres, in need for their second sickness certificate within the unit. Exclusion criteria are patients with specific diagnosis belonging to another unit within the psychiatric organization, and if the patient is assessed as being in an acute vulnerable situation where the planned intervention could negatively influence the situation. Register follow-ups on health care treatment, sick-leave spells, questions from SIA will be made 6 and 12 months later. The participant questionnaire will be sent 6 months after the intervention. Four studies are planned to evaluate the intervention.

The study is a collaborative project involving Region Västra Götaland. The research team comprise researchers from Göteborg University (C Andersson and K Holmgren) and from Region Västra Götaland (C Melin). The study has been submitted to the Regional Ethical Review Board.

Study Groups

Assessment of activity limitation

Assessment and analysis of activity limitation by occupational therapist using 2 registered instruments (SDO and DOA).

Group Type: EXPERIMENTAL

Assessment of activity limitations, SDO and DOA

Intervention Type: OTHER

The assessment is made with two instruments (DOA, SDO), and finally the occupational therapist includes the analysis and summary of activity limitations to the sickness certificate. For comparative reasons the participant will answer to a sociodemographic questionnaire focusing on work situation and sick leave

Control group: treatment as usual

Assessment of activity limitations according to usual routines

Group Type: ACTIVE_COMPARATOR

Control group

Intervention Type: OTHER

All assessments concerning activity limitations are made using usual routines, primarily by the sick-listing physician. For comparative reasons the participant will answer to a sociodemographic questionnaire focusing on work situation and sick leave

Eligibility Criteria

Inclusion Criteria

• All patients registered at the chosen psychiatric care centers, in need for their second or third sickness certificate within the unit.

Exclusion Criteria

• Patients with specific diagnosis belonging to another unit within the psychiatric organization.
• Patients assessed as being in an acute vulnerable situation where the planned intervention could negatively influence the situation e.g. having suicidal thoughts, or having such language difficulties that an interpreter is needed (which could complicate the understanding of the meaning of the intervention and cause unnecessary worries).
