An interventional study of Functional Capacity Evaluation in Sick Leave, Absenteeism and Return to Work, sponsored by KU Leuven. Recruiting at 8 sites in Belgium. Open to participants aged 18 Years to 65 Years. Per ClinicalTrials.gov, last updated 2024-01-29.
Sponsored by KU Leuven · Not applicable, Interventional, and Treatment
The goal of this clinical trial is to evaluate Functional Capacity Evaluations in persons on sick leave or work disability. The main questions it aims to answer are:
This is a randomized controlled trial (RCT). Participants in the control group will receive care-as-usual by the medical advisor. Participants in the intervention group will receive an FCE on top of care-as-usual. This is performed by an occupational therapist in their region, and a report of the FCE is delivered to the medical advisor. Both groups are asked to complete questionnaires at baseline, and after 3,6, and 9 months.
Researchers will compare questionnaire results from participants in the control and intervention group, to see if their workability (primary outcome), steps to return to work, expectations to return to work, return to work beliefs, time until (partial) reintegration, self-efficacy in return to work, pain scale, and illness perception (secondary outcomes) are affected differently.
This research project on the use of Functional Capacity Evaluations (FCE) within the context of benefit insurance in Belgium falls under the joint control of the National Institute for Sickness and Disability Insurance (RIZIV), the Haute École de Leonard Vinci and KU Leuven . KU Leuven hereby acts as the study's principal, but together with RIZIV and Haute École determines the objectives of the study as joint controllers.
An FCE consists of the evaluation of functional capacities based on medical reporting, observations and/or a series of standardised tests performed by an occupational therapist. This evaluation can give socially insured persons and medical advisors of the mutualities more insight into the participation possibilities of the socially insured person in function of the previous or next job. To date, the advisory doctor does not yet have the opportunity to have these evaluations carried out in Belgium. The aim of this study is therefore to examine the impact of these FCEs with regard to people on incapacity for work who meet the following conditions:
In this RCT, 10 consulting physicians, 30 occupational therapists, and 200 persons on incapacity will be recruited. Then, persons on sick leave/work disability are randomly divided into two groups: 1) Persons in the control group receive the usual counselling by the medical advisor. 2) Persons in the intervention group receive usual care and an FCE. In the latter group, the person on sick leave is matched by the researchers to an occupational therapist in his region, and is invited to a FCE. After the evaluation, the person reviews the results with the occupational therapist, and a report of the FCE is provided to the medical advisor. Finally, the person is contacted by the medical advisor if they wish to take certain actions as a result of the FCE report. To measure the impact of the FCE, the intervention and control groups thereby complete a questionnaire at four points in time: at baseline, after 3 months, after 6 months, and after 9 months. This questionnaire is composed of validated instruments, and in addition to background characteristics, it questions work ability, self-efficacy, expectations of returning to work, any (steps taken to) return to work, pain intensity, illness perception, and beliefs regarding returning to work.
As a second objective, the impact on the medical advisors' (and other parties') decision-making process will be investigated through qualitative interviews and focus groups. To this end, a process evaluation will be conducted. This includes an examination of the implementation of the study, the usability, feasibility and quality of FCEs and their reporting, and the underlying causal mechanisms of the intervention. Using interviews and focus groups with medical advisors the impact of the FCE on the decision-making process will be investigated. Using interviews with occupational therapists, return-to-work coordinators and mediators of the regional services the usability, feasibility and quality of the FCE will be investigated.
KU Leuven is the lead sponsor of 359 studies on the registry; 63 are open to participants now.

Exclusion Criteria:
In standard care, persons on sick leave/work disability are invited by the medical advisor for a consultation. If the patient is allocated to the control group (or if the patient did not agree to participate in the study), the medical advisor takes decisions based on the information at his disposal, e.g. start a return-to-work trajectory, to temporarily prolong sickness absence and disability, or to confirm definitive work disability. If they agree to participate, they are asked to complete four questionnaires: at baseline, at 3 months, 6 months, and 9 months.
In the intervention group, participants are referred to an occupational therapist to receive an FCE. Afterwards, the occupational therapist completes a standardized FCE-template, and conveys these recommendations to the medical advisor. This template includes a list of ICF categories important to the work context. The conclusion of the FCE includes: 1) The facilitators and barriers related to work-related physical, cognitive or psychological functioning, or related to environmental and/or psychosocial factors. 2) A recommendation on the current or last occupation or a reference occupation with or without adaptation and/or on reorientation, training, coaching. Based on the FCE results, the medical advisor can adapt his advice and communicate to the person on sick leave/work disability to advise him/her, or refer the person on sick leave/work disability to other partners (such as VDAB, FOREM, Actiris, or the RTW-coordinator).
Other: Functional Capacity Evaluation
In a FCE, an occupational therapist will evaluate a patient's ability to perform work-related tasks, using a battery of tests. Depending on the circumstances, he/she will for instance test fatigue, ask the patient to kneel, lift objects, or assess concentration. This assessment lasts ± 4 hours and includes physical tests and tests related to the (previous or reference) profession of the client. This means that an explicit match is made between the functional capacities of the patient (what is he/she capable of) and the demands of a certain job (what is he/she expected to do). Following this assessment, the occupational therapist will explain the results of this assessment to the patient. The evaluation will therefore take place during one or two visits.
Workability
The single-item first WAI (Work Ability Index) question is a self-report question in which the person rates his "current work ability compared with the lifetime best", with a score of 0 ("completely unable to work") up to 10 ("work ability at its lifetime best").
Time frame: measured at baseline, and 3, 6 and 9 months post baseline
Self-efficacy in the context of return-to-work
The self-efficacy return to work scale is a 10 item self-report questionnaire consisting of three subdomains of self-efficacy: (1) ability to cope with pain, (2) ability to obtain help from supervisor, and (3) ability to obtain help from co-workers. (Brouwer et al., 2009, 2010). There are five response options; for each item the person is asked to rate his/her confidence on a five-point scale (0 = not at all certain, 4 = completely certain). Subscores and an overall score (i.e., summative score) can be obtained, with higher scores indicating better return-to-work self-efficacy.
Time frame: measured at baseline, and 3, 6 and 9 months post baseline
Expectations to return-to-work
A single-item question "To what extent do you think you will return to work?" with the 4 response options: 1 (to a low degree); 2 (to a certain degree); 3 (to a high degree); 4 (do not know)
Time frame: measured at baseline, and 3, 6 and 9 months post baseline
Steps to return-to-work
The participants indicate which steps they have undertaken in their return-to-work, multiple answers are possible. Answers range from following training programmes, looking for jobs, undergoing work-oriented rehabilitation, to returning to work at a new or former employee.
Time frame: measured at baseline, and 3, 6 and 9 months post baseline
Pain scale
The Graded Chronic Pain Scale Revised (GCPS-R) is a 5-item self-report questionnaire assessing (1) current pain, (2) limitations in life or work abilities, (3) general pain, (4) enjoyment of life, (5) interference with general activity. For items 1 and 2, responses options are Never/Some days/Most days/Everyday, for items 3 responses options are the following: from 0 (No pain) to 10 (Pain as bad as you can imagine) while for items 4 and 5 responses options are the following : from 0 (does not interfere) to 10 (completely interferes).
Time frame: measured at baseline, and 3, 6 and 9 months post baseline
Illness perception
The Brief IPQ has nine items, it is designed to measure patients' cognitive and emotional representations of their illness including consequences (item 1), timeline (item 2), personal control (item 3), treatment control (item 4), identity (item 5), coherence (item 6), concern (item 7), emotional response (item 8), and causes (item 9) (Broadbent et al., 2006). All of the items except the causal question are rated using a 0-to 10 response scale. Increases in item scores represent linear increases in the dimension measured.
Time frame: measured at baseline, and 3, 6 and 9 months post baseline
Return-to-work beliefs
The RTW Beliefs questionnaire is composed of 12 items divided into four subscale of general direct measures: intention (i.e., "I expect to/want to/intend to ..."), attitude (i.e., "RTW is for me: harmful-beneficial/ good-bad/pleasant-unpleasant/worthless-useful"), subjective norms (i.e., "It is expected of me that I should ... /I feel under social pressure to ... /People who are important to me want me to ..." ) , and perceived behavioural control (i.e., "I'm confident that I could ... / for me RTW is (easy-difficult).
Time frame: measured at baseline, and 3, 6 and 9 months post baseline
Plan to share: Yes — Apart from the researchers, the National Institute for Health and Disability Insurance (NIHDI) will have access to the pseudonymised questionnaire data, as specified in a GDPR-contract. Selected questionnaire data as well as the FCE-results will be available to the occupational therapists, the medical advisor, the return-to-work coordinator, and the mediator of the regional services.
