Elaboration of the contextual factors of the ICF for Occupational Health Care

Development of an ontology to characterize mental functioning

PURPOSE OF THE ARTICLE

This article describes a conceptual and methodological approach to integrating functional information into an ontology to categorize mental functioning, which to date is an under-developed area of classification, and supports our work with the United States (U.S.) Social Security Administration (SSA).

DESIGN AND METHODOLOGICAL PROCEDURES

Conceptualizing and defining mental functioning was paramount to develop natural language processing (NLP) tools to support our use case. The International Classification of Functioning, Disability, and Health (ICF) was the framework used to conceptualize mental functioning at the activities and participation level in clinical records. To address challenges that arose when applying the ICF as to what should or should not be classified as mental functioning, a mental functioning domain ontology was developed that rearranged, reclassified and incorporated all ICF key components, concepts, classifications, and their definitions.

CONCLUSIONS

Challenges emerged in the extent to which we could directly align components in the ICF into an applied ontology of mental functioning. These conceptual challenges required rearrangement of ICF components to adequately support our use case within the social security disability determination process. Findings also have implications to support future NLP efforts for behavioral health outcomes and policy research.

Systematic review and tools appraisal of prognostic factors of return to work in workers on sick leave due to musculoskeletal and common mental disorders

With the overall objective of providing implication for clinical and research practices regarding the identification and measurement of modifiable predicting factors for return to work (RTW) in people with musculoskeletal disorders (MSDs) and common mental disorders (CMDs), this study 1) systematically examined and synthetized the research evidence available in the literature on the topic, and 2) critically evaluated the tools used to measure each identified factor. A systematic search of prognostic studies was conducted, considering four groups of keywords: 1) population (i.e., MSDs or CMDs), 2) study design (prospective), 3) modifiable factors, 4) outcomes of interest (i.e., RTW). Studies showing high risk of bias were eliminated. Tools used to measure prognostic factors were assessed using psychometric and usability criteria. From the 78 studies that met inclusion criteria, 19 (for MSDs) and 5 (for CMDs) factors reaching moderate or strong evidence were extracted. These factors included work accommodations, RTW expectations, job demands (physical), job demands (psychological), job strain, work ability, RTW self-efficacy, expectations of recovery, locus of control, referred pain (back pain), activities as assessed with disability questionnaires, pain catastrophizing, coping strategies, fears, illness behaviours, mental vitality, a positive health change, sleep quality, and participation. Measurement tools ranged from single-item tools to multi-item standardized questionnaires or subscales. The former generally showed low psychometric properties but excellent usability, whereas the later showed good to excellent psychometric properties and variable usability. The rigorous approach to the selection of eligible studies allowed the identification of a relatively small set of prognostic factors, but with a higher level of certainty. For each factor, the present tool assessment allows an informed choice to balance psychometric and usability criteria.

Health status and ergonomics education: A comparison between student nurses and first-year nursing staff

AIMS

To (a) compare student nurses' health status and levels of ergonomics knowledge and awareness to those of first-year nursing staff and (b) investigate the association between nurses' ergonomic compliance and health status with their educational preparedness.

DESIGN

This cohort study compared ergonomics awareness and knowledge, and health status of nurses when they were students and after their first-year working in medical facilities.

METHODS

In total, 133 4th-year student nurses completed a survey; 45 of them completed a second survey after working 1 year in a medical facility. Their health status was compared over time using repeated-measures ANOVA. Correlation tests were used to analyse associations between ergonomics knowledge and awareness, health status, demographic variables and educational preparedness.

RESULTS

Respondents in both surveys displayed weak knowledge of ergonomic principles significantly associated with increased pain intensity and educational preparedness.

PATIENT CONTRIBUTION

Ergonomics training should be expanded during nursing studies and first-year training to prevent long-term health disorders.

The dizzying cycle: a qualitative study showing the effects of vestibular disorders and stress on work experience

OBJECTIVE

Quantitative studies have explored the work abilities of persons with specific vestibular-related symptoms, but there seems to be a dearth of research that has explored the work experience of persons-with- vestibular- disorders, so this qualitative study explored this phenomenon.

DESIGN

Audio-recorded semi-structured interviews were conducted online. Thematic analysis was used to analyse the transcripts. Together, two researchers coded the transcripts and deductively identified the main themes on the main components of the expanded International Classification of Functioning, Disability, and Health scheme, and thereafter generated the sub-themes inductively.

STUDY SAMPLE

Fourteen people with various vestibular disorders and occupations in South Africa participated in the study.

RESULTS

Participants reported having difficulty performing work-related tasks requiring attention to detail and ambulation, and work environmental conditions triggered their vestibular-related symptoms. Some participants received time off from work and support from their supervisors and colleagues, while others did not. Seeking mental services allowed them to overcome their negative feelings, medication suppressed their vestibular-related symptoms, and vestibular rehabilitation allowed them to focus on their work.

CONCLUSION

Vestibular-related symptoms may hinder persons- with- vestibular- disorders from completing and participating in work-related activities, which may result in them experiencing negative feelings. The nature of some of the work-related tasks that they need to complete and experiencing negative feelings may trigger their vestibular-related symptoms. Together, the work-related activity limitations, participation restrictions, and environmental and personal factors may cause persons- with- vestibular- disorders to experience disability in their workplaces. To prevent this potential disability, persons with vestibular disorders should be supported by and receive workplace accommodations. Furthermore, they should be enrolled into work rehabilitation programmes that include, vestibular rehabilitation, medication regimens, and mental health services.

Developing a Training in Motivational Counselling to Promote Return to Work: An Intervention Mapping Approach

PURPOSE

Due to the Belgian health insurance system's controlling nature, work-disabled claimants can feel forced to return to work (RTW), increasing their risk of relapse. RTW out of interest or importance is considered more sustainable. Such autonomous motivation for RTW can be promoted through 'motivational counselling', an integration of self-determination theory and motivational interviewing. To adopt this, health insurance practitioners need training, which can be designed through intervention mapping as an evidence-based planning tool. This paper reports on the development of a motivational counselling training for health insurance practitioners.

METHODS

Intervention mapping's six steps guided the formulation of programme goals and learning outcomes, matching the context. We then identified change methods which were translated into practical components. Together with the health insurances' input, this resulted in a concrete training programme with an implementation and evaluation plan.

RESULTS

The training was designed to increase practitioners' knowledge, skills, and beliefs relevant for learning motivational counselling, which also requires solution-focused strategies. Methods like guided practice were translated into built-in exercises, feedback, and information, which were implemented through an online training format of five sessions including one follow-up.

CONCLUSION

Reporting about training development increases understanding of its effectiveness and implementation, which will be evaluated via pre- and post-training data collection amongst practitioners. Future trainings can benefit from this by accounting for health insurances' organizational barriers or building on the training's evidence-based backbone whilst only requiring specific adaptations for other stakeholders and contexts. Further research should evaluate motivational counselling's impact on claimants' RTW trajectories.

Machine Learning Based Linking of Patient Reported Outcome Measures to WHO International Classification of Functioning, Disability, and Health Activity/Participation Categories

BACKGROUND

In the primary and secondary medical health sector, patient reported outcome measures (PROMs) are widely used to assess a patient's disease-related functional health state. However, the World Health Organization (WHO), in its recently adopted resolution on "strengthening rehabilitation in all health systems", encourages that all health sectors, not only the rehabilitation sector, classify a patient's functioning and health state according to the International Classification of Functioning, Disability and Health (ICF).

AIM

This research sought to optimize machine learning (ML) methods that fully and automatically link information collected from PROMs in persons with unspecific chronic low back pain (cLBP) to limitations in activities and restrictions in participation that are listed in the WHO core set categories for LBP. The study also aimed to identify the minimal set of PROMs necessary for linking without compromising performance.

METHODS

A total of 806 patients with cLBP completed a comprehensive set of validated PROMs and were interviewed by clinical psychologists who assessed patients' performance in activity limitations and restrictions in participation according to the ICF brief core set for low back pain (LBP). The information collected was then utilized to further develop random forest (RF) methods that classified the presence or absence of a problem within each of the activity participation ICF categories of the ICF core set for LBP. Further analyses identified those PROM items relevant to the linking process and validated the respective linking performance that utilized a minimal subset of items.

RESULTS

Compared to a recently developed ML linking method, receiver operating characteristic curve (ROC-AUC) values for the novel RF methods showed overall improved performance, with AUC values ranging from 0.73 for the ICF category d850 to 0.81 for the ICF category d540. Variable importance measurements revealed that minimal subsets of either 24 or 15 important PROM variables (out of 80 items included in full set of PROMs) would show similar linking performance.

CONCLUSIONS

Findings suggest that our optimized ML based methods more accurately predict the presence or absence of limitations and restrictions listed in ICF core categories for cLBP. In addition, this accurate performance would not suffer if the list of PROM items was reduced to a minimum of 15 out of 80 items assessed.

Functioning of People with Lipoedema According to All Domains of the International Classification of Functioning, Disability and Health: A Scoping Review

Lipoedema is a painful non-pitting diffuse "fatty" swelling, usually confined to the legs, that occurs mainly in women. This scoping review aimed to provide an overview of the available research on the functioning of people with lipoedema, according to the International Classification of Functioning, Disability and Health (ICF) framework. Relevant publications and gray literature were retrieved until October 2022. The results sections of each publication were organized using a thematic framework approach. All included studies reported at least one outcome fitting within the domains of body functions and body structures, with most studies focusing on the categories of "sensation of pain", "immunological system functions", and "weight maintenance functions". The ICF domains of activities and participation and environmental factors were mentioned in a small number of the included studies (17 and 13%, respectively), while the domain of personal factors was studied in half of the included studies. In conclusion, the emphasis of lipoedema research is on its description from a disorder-oriented point of view in the form of body functions and body structures, with a lack of information about the other domains of functioning.

IMBA-ICF linking by integrating consensus methods: How group consensus of experts can contribute to in-depth linking of instruments to the ICF

BACKGROUND

A frame of reference is needed to increase the comparability of vocational rehabilitation assessment instruments and the interpretation of their results. The International Classification of Functioning, Disability and Health (ICF) is a relevant framework, and when linking rules are used, items from existing assessment instruments can be linked to the appropriate categories as described in the ICF.

OBJECTIVE

To develop an adapted linking methodology in which experts are involved by means of the application of consensus methods and to transfer this result in a step-by-step set of guidelines, supporting researchers and professionals, linking complex instruments to the ICF.

METHODS

The main researcher developed the initial linking of the Integration von Menschen mit Behinderungen in die Arbeitswelt (IMBA) to the ICF by rigorously applying the refined ICF linking rules. To validate this linking, the Delphi and nominal group technique was integrated through different steps, and experts were involved in the process. The method section describes the linking process chronologically with focuses on the used approach, the involvement of experts, and the processing of the output.

RESULTS

The results are presented in a 7-step set of guidelines describing the chronological process from the initial to the validated linking. These guidelines describe the core elements in the application of the linking rules and consensus methods in a manual for researchers who are interested in linking complex instruments to the ICF by involving experts.

CONCLUSIONS

The Delphi and nominal group technique can be successfully integrated in the linking process, making it possible to involve experts in linking complex instruments to the ICF. A homogeneous composition of the expert panel in terms of knowledge, a heterogeneous composition in terms of setting, a rigorous and repeated application of the linking rules, and structured processing of the output are essential to achieve a valid linking.

Applying the ICF codes, flag model and C-OAR-SE in the development of return-to-work assessment scale for stroke survivors

BACKGROUND

The Return-to-Work Assessment Scale (RAS) was developed in 2021 by Ibikunle et al. to assess return-to-work among post-stroke survivors.

OBJECTIVE

The aim of this study was to describe how the conceptual (flag model and ICF) and theoretical framework (C-OAR-SE) were used in developing the RAS.

METHOD

The development of the RAS consisted of three phases: (i) Initial item generation (ii) Face and content validity (iii) Psychometric testing. With each phase embracing the flag model, international classification of functioning, disability and health (ICF) and the C-OAR-SE an acronym for the six aspects of the theory: 'C' [construct definition], 'OAR' [object representation, attribute classification, and rater entity identification], and 'SE' [selection of item type and answer scale, as well as, enumeration].

RESULTS

A triangulated approach drawn on three separate theories and models. Phase one was developed by using the flag model which provided the semi-structured open ended questions that materialized into the draft instrument while phases two and three were developed using the ICF and the C-OAR-SE. The scale consists of two sections, A and B. Section A comprises general information about post-stroke survivors, which would not be scored, while section B includes three parts that are important to consider when deciding to return-to-work.

CONCLUSION

An instrument called RAS was developed, an excellent, internally consistent, as well as reliable tool that has demonstrated good group and structural validity.

Development of the core of an ICF-based instrument for the assessment of work capacity and guidance in return to work of employees on sick leave: a multidisciplinary modified Delphi study

BACKGROUND

Several occupational health disciplines are involved in return to work guidance, implying that good interdisciplinary collaboration is important. A shared conceptual framework and a common language for the assessment of work capacity and guidance in return to work is expected to be at the benefit of appropriate and sustainable employability of sick employees. The International Classification of Functioning, Disability and Health (ICF) can be considered a shared conceptual framework and is also promising in terms of a common language. The purpose of the current study is to reach multidisciplinary consensus among occupational health professionals on the content of an ICF-based instrument for the assessment of work capacity and guidance in return to work.

METHODS

To obtain multidisciplinary consensus we conducted a modified Delphi study among twelve occupational health experts, including four occupational physicians, four insurance physicians and four labour experts. The study included two e-mail rounds and two virtual meetings. In the consecutive rounds the experts assessed ICF items as well as a list of non-ICF-based work-related environmental factors on their relevance for the assessment of the work capacity and guidance in return to work together with their interpretability.

RESULTS

The four consecutive Delphi rounds resulted in 20 items that are minimally needed for the assessment of the work capacity and return to work possibilities of employees on sick leave. The final list included six items on personal functioning, seven items on social functioning and seven items on physical functioning.

CONCLUSIONS

This set of items forms the core of an ICF-based instrument, which is expected to facilitate interdisciplinary and intradisciplinary communication because of the use of a shared conceptual framework. As such, it should be of help in the guidance in return to work of employees on sick leave and contribute to appropriate and sustainable employability.

Perceptions of medical advisers on ICF core-sets’ use for evaluating work incapacity related to back pain in French-speaking Belgium

BACKGROUND: There is willingness in Europe to implement the use of a biopsychosocial model such as the International Classification of Functioning, Disability and Health (ICF) for assessing work incapacity. OBJECTIVE: A preliminary study was conducted to investigate the perceptions of medical advisers on the value of structuring clients’ biopsychosocial information in an ICF-based report. METHOD: A sample (n = 101) received a perception questionnaire after watching two comparative videos based on a clinical case. Questions relating to work incapacity were also asked. The data was analysed using quantitative methods. Comments were also collected. RESULTS: Before knowing the ICF-based report, 61.96% of the respondents believed a return to work seems possible by providing adapted work or a different job. There is an increase of 8.69 pp (p-value: 0.077) after reading the report. Opening up the initial sample to more insurance physicians (n = 119), the difference is more significant (p-value: 0.012). Also, 71.9% of respondents believe they have a better view of the client’s biopsychosocial situation after reading the report. Respondents recognise the clinical and diagnostic relevance of ICF but say it cannot be used at the moment for various reasons, such as the time required or the need for a multidisciplinary team and effective coordination. Older respondents are less enthusiastic about the appropriateness of using ICF. CONCLUSION: The respondents identify an added value in having a biopsychosocial based-report. After learning about the report, more physicians see opportunities for professional re-integration than before. The medical advisers and their team must be strengthened and receive a clear role in order to empower them.

Opportunities, barriers and facilitators of an indicated prevention strategy to prevent future long-term sickness absence in SMEs: A qualitative study

BACKGROUND

The efficacy of an indicated prevention strategy for long-term absence due to sickness has been demonstrated and is implemented in multinational companies. Such a strategy may also be beneficial for small and medium-sized enterprises (SMEs). However, due to the different contexts, adoption, and implementation of this strategy in SMEs may be quite different.

OBJECTIVE

This study aims to investigate the opportunities, barriers, and facilitators for adoption and implementation of this preventive strategy, as anticipated by employers and employees of SMEs.

METHODS

A qualitative needs assessment was conducted using semi-structured interviews with higher managers (n = 15) and a focus group with employees (n = 8). Purposive sampling was used, and data were analyzed using content analysis.

RESULTS

Employers had positive expectations concerning the gains of the preventive strategy, whereas employees had more reservations. Anticipated gains and intentions to implement the preventive strategy were rooted in underlying conceptions of the causes of sickness absence and the responsibilities of stakeholders. One key barrier shared across employers and employees concerned the potential lack of confidentiality. For employees, the role of the occupational health professional in the prevention of sickness absence was perceived as uncommon. Employers stressed lack of capacity and resources as a barrier, whereas employees stressed lack of follow-up by the employer as a barrier.

CONCLUSIONS

SMEs are considerably receptive to the implementation of an indicated prevention strategy for long-term absence. Insight into the barriers and facilitators gives clues for wider and optimal implementation across a wider range of organizational settings.

Communication partner perspectives of aphasia self-management and the role of technology: an in-depth qualitative exploration

PURPOSE

"Self-management" empowers individuals to take responsibility for their healthcare through skill-building, personal growth, and self-efficacy related to chronic health condition management. Self-management approaches may benefit people with aphasia (PwA); however, PwA are often excluded from stroke self-management research and there is no published research reporting on aphasia-specific self-management programs. Communication partners (CPs) are involved in the rehabilitation and day-to-day lives of PwA, thus giving them unique insights and knowledge of PwA needs. The present study aimed to investigate CP experiences and perspectives regarding aphasia self-management and to explore CP perceptions of the use of technology in aphasia self-management.

METHODS

In-depth, semi-structured interviews with 14 CPs living in Australia. Interview data was analysed using qualitative content analysis.

RESULTS

Analysis revealed six core themes: (1) aphasia self-management is embedded into everyday life, (2) CPs provide comprehensive self-management support, (3) speech-language pathologists (SLPs) provide tools and support to enable PwA to self-manage, (4) aphasia self-management can be enhanced by technological supports, (5) potential positive outcomes of aphasia self-management, and (6) factors influencing successful aphasia self-management.

CONCLUSIONS

Aphasia self-management programs should focus on individual needs, functional communication in daily life, and social interaction. PwA and CPs are central to these programs, assisted by SLPs. Technology should be explored to augment aphasia self-management.Implications for RehabilitationCommunication partners suggest that people with aphasia are already engaging in aspects of self-management and that more formal aphasia-specific self-management approaches may be beneficial.Dedicated aphasia self-management programs should be situated in daily life with a focus on functional communication, life participation, confidence, and independence.Communication partners, speech-language pathologists, and technology are key support sources for aphasia self-management.Further input should be sought from communication partners in the development of aphasia self-management programs.

Linking of the ‘Integration von Menschen mit Behinderungen in die Arbeitswelt’ (IMBA) to the ‘International Classification of Functioning, Disability and Health’ (ICF)

BACKGROUND: The assessment of work capacity, workable work and the need for a common language is challenging in labour market policy. Being a specific instrument to facilitate Return To Work (RTW), the Integration von Menschen mit Behinderungen in die Arbeitswelt (IMBA) might facilitate the documentation of the individual’s work capacity, the job-related workload and the match between these two elements. Since the International Classification of Functioning, Disability and Health (ICF) is worldwide recognized as frame of reference in RTW, this paper presents the linking of IMBA to the ICF, since this is assumed to be beneficial to support RTW. OBJECTIVE: The establishment of the IMBA-ICF linking in order to study 1) the relationship between IMBA and ICF; 2) the content comparison of IMBA with work-related ICF core sets; and 3) the extent to which the linking addresses the challenges in RTW policy. METHODS: A content comparison of IMBA and ICF was conducted, using a 7- step linking methodology in which the Delphi and Nominal Group Technique are integrated in the implementation of the ICF linking rules. An explorative conversion of the scoring systems of IMBA and ICF was established based on expert opinions. RESULTS: In the main 70 IMBA items, 107 concepts have been identified of which 94 were linked to 87 different ICF categories. Body functions and activities and participation are the most presented ICF components in contrast to the environmental factors. IMBA items regarding occupational safety and work organization are respectively ‘not covered’ and ‘not defined’ in ICF. CONCLUSIONS: An integration of IMBA and ICF addresses the challenges in RTW policy in the assessment of work capacity, workable work and the need for a common language. In order to do so, extension of ICF terminology regarding ‘occupational safety’ and ‘work organization’ is priority. In depth quantitative research is necessary to support the conversion of both scoring systems.

Factors relevant to work participation from the perspective of adults with developmental dyslexia: a systematic review of qualitative studies

Background

This review is focused on workers with developmental dyslexia (DD). In this review DD is considered an expression of neurodiversity, a consequence of a natural variant of the brain. Evidence was synthesized to explore which factors workers with DD consider relevant for their participation in work and whether these factors reflect shifts in the concepts of health and sustainable employability. The factors were classified according to the International Classification of Functioning, Disability and Health (ICF), adapted for occupational health.

Methods

A systematic review of qualitative studies was performed. Two search strings were used to determine the population and the context of work. The factors were classified using a recently proposed rearrangement of the ICF scheme that places participation in a central position and incorporates preliminary lists of work-related environmental factors and personal factors.

Results

Fifty-one factors were found that appeared in 35% or more of the included studies and that were relevant to work participation according to the workers themselves. These factors were dispersed over all ICF categories. In the category Functions and Structures (11 factors), most of the factors had negative connotations. In the category Activities (9 factors), all the factors cause difficulties, except speaking (which is ambiguous). In the category Participation (4 factors), the formal relationships are important for the degree of participation. Overall, more than half of the factors are environmental (18) or personal (9) and they both hinder and facilitate work participation.

Conclusions

The results of this review give an indication for the importance of the biopsychosocial model as a relevant approach for people with a disability in the world of work. This review also adds data for the usefulness of the proposals for the reconsideration of the ICF scheme. The data has not (yet) returned any visible trends revealing that the concept of neurodiversity is common in organizations.

How to Facilitate Adherence to Cardiac Rehabilitation in Primary Health Settings for Ischaemic Heart Disease Patients. The Perspectives of Health Professionals

Background

Cardiac rehabilitation (CR) is a class 1A recommendation and an integrated part of standard treatment for patients with cardiac disease. In Denmark, CR adheres to European guidelines, it is group-based and partly conducted in primary health settings. Despite high evidence for the benefits of CR, it remains underutilized. How to facilitate CR adherence in primary health settings is poorly understood.

Aim

This study explores health professional's perspectives on how to facilitate CR adherence for patients with ischaemic heart disease in primary health settings.

Methods

Data were collected through focus group discussions. Respondents were health professionals specialized in and working with CR in primary health settings. Data were analyzed using thematic analysis.

Results

Eleven health professionals participated in two focus group discussions. Five themes emerged as facilitators of CR; (1) placing the person at the center, (2) coherent programme, (3) flow of information, (4) contextual factors, and (5) feeling of belonging.

Conclusion

This study illuminates the complexity of facilitating adherence to CR in primary health settings and provides ways in which health professionals may facilitate adherence. Placing the person at the center is pivotal and may be done by adapting CR offers to patients' social context, culture and life circumstances and ensuring a feeling of belonging. The rhetoric related to CR should be positive and throughout the entire course of treatment health professionals should possess a generic and collective approach to and view of CR. Perceiving these elements as potential facilitators is of vital importance and addressing them may facilitate adherence.

'Work is a motivator in life' Strategies in managing work participation among highly educated employees with depression

BACKGROUND

Work participation among employees with depression is hampered due to cognitive impairments. Although studies show higher levels of work disability among people with a lower education, highly educated employees may encounter specific challenges in fulfilling their work role due to the cognitive impairments of depression, as they often perform cognitively demanding jobs. There is little knowledge about their challenges and opportunities with regard to work participation.

OBJECTIVE

To investigate how highly educated employees with depression manage work participation by focusing on their views on opportunities and challenges in fulfilling their work role.

METHODS

Eight individual interviews with highly educated employees with depression were conducted. Transcripts were analysed using qualitative content analysis.

RESULTS

The analysis revealed four categories: struggling with acknowledging depression and disclosure; fear of being stigmatised at work; work is a motivator in life; and striving to fulfil the work role at the expense of private life activities.

CONCLUSIONS

Highly educated employees with depression need guidance regarding the disclosure of information about health issues and work ability. To successfully manage their work role, they need a clear plan with outlined tasks, demands and goals. Healthcare professionals and workplaces should support them in setting limits with regard to work tasks and working hours.

Viewpoint: An Information Extraction Framework for Disability Determination Using a Mental Functioning Use-Case (Preprint)

Natural language processing (NLP) in health care enables transformation of complex narrative information into high value products such as clinical decision support and adverse event monitoring in real time via the electronic health record (EHR). However, information technologies for mental health have consistently lagged because of the complexity of measuring and modeling mental health and illness. The use of NLP to support management of mental health conditions is a viable topic that has not been explored in depth. This paper provides a framework for the advanced application of NLP methods to identify, extract, and organize information on mental health and functioning to inform the decision-making process applied to assessing mental health. We present a use-case related to work disability, guided by the disability determination process of the US Social Security Administration (SSA). From this perspective, the following questions must be addressed about each problem that leads to a disability benefits claim: When did the problem occur and how long has it existed? How severe is it? Does it affect the person’s ability to work? and What is the source of the evidence about the problem? Our framework includes 4 dimensions of medical information that are central to assessing disability—temporal sequence and duration, severity, context, and information source. We describe key aspects of each dimension and promising approaches for application in mental functioning. For example, to address temporality, a complete functional timeline must be created with all relevant aspects of functioning such as intermittence, persistence, and recurrence. Severity of mental health symptoms can be successfully identified and extracted on a 4-level ordinal scale from absent to severe. Some NLP work has been reported on the extraction of context for specific cases of wheelchair use in clinical settings. We discuss the links between the task of information source assessment and work on source attribution, coreference resolution, event extraction, and rule-based methods. Gaps were identified in NLP applications that directly applied to the framework and in existing relevant annotated data sets. We highlighted NLP methods with the potential for advanced application in the field of mental functioning. Findings of this work will inform the development of instruments for supporting SSA adjudicators in their disability determination process. The 4 dimensions of medical information may have relevance for a broad array of individuals and organizations responsible for assessing mental health function and ability. Further, our framework with 4 specific dimensions presents significant opportunity for the application of NLP in the realm of mental health and functioning beyond the SSA setting, and it may support the development of robust tools and methods for decision-making related to clinical care, program implementation, and other outcomes.

Needs for occupational assistance among young adults with ADHD to deal with executive impairments and promote occupational participation - a qualitative study

PURPOSE

To examine perceived aspects of importance among young adults with ADHD to participate and engage in occupational activities, and to explain how support from occupational specialists can assist them to deal with executive impairments.

MATERIALS AND METHODS

Individual interviews with eight young adults with attention-deficit/hyperactivity disorder. The interview guide was based on assumptions derived from the literature regarding executive functioning and issues related to participation in occupational activities, alongside the needs for social support. Interview transcripts were analysed using qualitative content analysis.

RESULTS

Four categories emerged from the analysed interviews: (1) Being involved in an occupational environment fulfils a need for social contact, (2) Occupational activities must be clear and within interest (3) Self-confidence and daily routines are prerequisites for occupational participation (4) Having a lifeline providing continuous support is important.

CONCLUSIONS

Routines, interest and structure in everyday life are important to engage in occupational activities. There is a need for continuous support from a trusted person to establish and maintain healthy daily routines. Occupational specialists can be a vital resource, as they possess specific knowledge on the possibilities for occupation, and additionally, they can fulfil the young adults' needs for continuous support. There is a need for studies questioning how some young adults with ADHD fulfil their work role despite executive impairments. Focusing on executive functioning can be a valuable supplement to the focus on specific diagnoses in research and practice.

Evaluation of a profile comparison system for the inclusion of people with disabilities in horticulture: A case study in Austria

BACKGROUND

To promote the successful and sustainable inclusion of people with disabilities in different activities such as work, more precise job matching efforts may be of value, especially because people with disabilities are employed at a lower rate than people without disabilities. Requirement profiles as well as profile comparisons have not yet been recorded for horticultural work processes.

OBJECTIVE

The aim of this study was to document precisely the work process of the cuttings production of the flower tradescantia and to compare the capabilities of people with disabilities with the requirements for this work process for the purpose of verifying that the tool employed was usable.

METHODS

A skilled worker performed the cuttings production of tradescantias according to good horticultural practice. Additionally, five people with disabilities participated in this study. On the one hand, a structured questionnaire was used to collect the data. On the other hand, the work processes were documented with video recordings and described related to REFA (Association for Work Design, Business Organization and Corporate Development) and evaluated according to IMBA (Integration of People with Disabilities into the Working Environment).

RESULTS

Apart from the too long working hours, the work in the cuttings production was feasible for the five subjects who had different types of disabilities. There were situations of underchallenges of different degrees, but no overchallenges. It was necessary to assess each subject individually for the risk of accident.

CONCLUSIONS

IMBA proved to be an effective tool to evaluate and analyse work activities for the purpose of including people with disabilities into horticultural work processes. Thus, it has the potential to facilitate a socially sustainable and skill-oriented work participation for persons with disabilities.

Barriers to and Facilitators of Sustained Employment: A Qualitative Study of Experiences in Dutch Patients With CKD

RATIONALE & OBJECTIVE

Although patients with chronic kidney disease (CKD) are at risk for work disability and loss of employment, not all experience work disruption. We aimed to describe the barriers to and facilitators of sustained employment experienced by Dutch patients with CKD.

STUDY DESIGN

Qualitative study using semistructured interviews.

SETTING & PARTICIPANTS

27 patients with CKD glomerular filtration rate categories 3b-5 (G3b-G5) from 4 nephrology outpatient clinics in The Netherlands.

ANALYTICAL APPROACH

Content analyses with constant comparison of interview data based on the International Classification of Functioning, Disability and Health framework.

RESULTS

Participants were 6 patients with CKD G3b-G4, 8 patients receiving maintenance dialysis, and 13 patients with functioning kidney transplants. We identified health-related barriers (symptoms, physical toll of dialysis/transplantation, limited work capacity) and facilitators (few physical symptoms, successful posttransplantation recovery, absence of comorbidities, good physical condition), personal barriers (psychological impact, limited work experience) and facilitators (positive disposition, job satisfaction, work attitude, person-job fit), and environmental barriers and facilitators. Environmental barriers were related to nephrology care (waiting time, use of a hemodialysis catheter) and work context (reorganization, temporary contract, working hours, physical demands); environmental facilitators were related to nephrology care (personalized dialysis, preemptive transplant), work context (large employer, social climate, job requiring mental rather than physical labor, flexible working hours, adjustment of work tasks, reduced hours, remote working, support at work, peritoneal dialysis exchange facility), and support at home. Occupational health services and social security could be barriers or facilitators.

LIMITATIONS

The study sample of Dutch patients may limit the transferability of these findings to other countries.

CONCLUSIONS

The wide range of barriers and facilitators in all International Classification of Functioning, Disability and Health components suggests great diversity among patients and their circumstances. These findings underline the importance of personalized nephrology and occupational health care as well as the importance of individually tailored workplace accommodations to promote sustained employment for patients with CKD.

Content Validation of a Practice-Based Work Capacity Assessment Instrument Using ICF Core Sets

PURPOSE

A shift from providing long-term disability benefits to promoting work reintegration of people with remaining work capacity in many countries requires new instruments for work capacity assessments. Recently, a practice-based instrument addressing biopsychosocial aspects of functioning, the Social Medical Work Capacity instrument (SMWC), was developed. Our aim was to examine the content validity of the SMWC using ICF core sets.

METHODS

First, we conducted a systematic search to identify relevant ICF core sets for the working age population. Second the content of these core sets were mapped to assess the relevance and comprehensiveness of the SMWC. Next, we compared the content of the SMWC with the ICF-core sets.

RESULTS

Two work-related core sets and 31 disease-specific core sets were identified. The SMWC and the two work-related core sets overlap on 47 categories. Compared to the work-related core sets, the Body Functions and Activities and Participation are well represented in the new instrument, while the component Environmental factors is under-represented. Compared to the disease-specific core sets, items related to the social and domestic environmental factors are under-represented, while the SMWC included work-related factors complementary to the ICF.

CONCLUSION

The SMWC content seems relevant, but could be more comprehensive for the purpose of individual work capacity assessments. To improve assessing relevant biopsychosocial aspects, it is recommended to extend the instrument by adding personal and environmental (work- and social-related) factors as well as a more tailored use of the SMWC for assessing work capacity of persons with specific diseases or underlying illness.

Automated Coding of Under-Studied Medical Concept Domains: Linking Physical Activity Reports to the International Classification of Functioning, Disability, and Health

Linking clinical narratives to standardized vocabularies and coding systems is a key component of unlocking the information in medical text for analysis. However, many domains of medical concepts, such as functional outcomes and social determinants of health, lack well-developed terminologies that can support effective coding of medical text. We present a framework for developing natural language processing (NLP) technologies for automated coding of medical information in under-studied domains, and demonstrate its applicability through a case study on physical mobility function. Mobility function is a component of many health measures, from post-acute care and surgical outcomes to chronic frailty and disability, and is represented as one domain of human activity in the International Classification of Functioning, Disability, and Health (ICF). However, mobility and other types of functional activity remain under-studied in the medical informatics literature, and neither the ICF nor commonly-used medical terminologies capture functional status terminology in practice. We investigated two data-driven paradigms, classification and candidate selection, to link narrative observations of mobility status to standardized ICF codes, using a dataset of clinical narratives from physical therapy encounters. Recent advances in language modeling and word embedding were used as features for established machine learning models and a novel deep learning approach, achieving a macro-averaged F-1 score of 84% on linking mobility activity reports to ICF codes. Both classification and candidate selection approaches present distinct strengths for automated coding in under-studied domains, and we highlight that the combination of (i) a small annotated data set; (ii) expert definitions of codes of interest; and (iii) a representative text corpus is sufficient to produce high-performing automated coding systems. This research has implications for continued development of language technologies to analyze functional status information, and the ongoing growth of NLP tools for a variety of specialized applications in clinical care and research.

Remodeling of the ICF: A commentary

Since its publication in 2001 the International Classification of Functioning, Disability and Health (ICF) has attracted debate about the content and the model presented. After almost 20 years use, regular updating since 2008 and with the prospect of a new edition in 2020 there is increasing interest in the ICF as a tool to meet contemporary information requirements. Information on functioning is important across not only health systems, but all areas where change in functioning is important: education, employment, and social welfare for example. This commentary responds to the issues raised in a commentary by Mitra & Shakespeare in 2019 and supports review of the ICF in the current context by informing users and providers of data on human functioning how they might engage in the maintenance, updating, and modernisation of the ICF.

Issues facing employability assessment in total and permanent disability insurance claims: A rehabilitation perspective

BACKGROUND

Expert employment information helps life insurers to decide total and permanent disability claims. The employability assessment model was developed a decade ago by rehabilitation counselors and has not been critically examined.

OBJECTIVE

This exploratory descriptive study aims to elicit key issues of employability assessment within Australian life insurance.

METHODS

Ten rehabilitation advisors with knowledge of employability assessment in the total and permanent disability sector participated in a single focus group. They each nominated issues of concern about employability assessment. These issues were collated then discussed within the group. Qualitative thematic analysis was used to identify key issues.

RESULTS

The predominant theme was the forensic nature of employment evidence. There were three categories of key issues. First, assessment providers- their training, qualifications, experience, and role. Second, methodology- approaches that provide most realistic information about a claimant's likelihood of work. Third, policy definitions that illustrate reliance on legal interpretation of employability.

CONCLUSIONS

To withstand legal scrutiny, the credentials of providers, assessment methodology, and quality of forensic reports are key issues which need to be addressed. This foundational study will contribute to broader research on this topic, with implications particularly for rehabilitation, life insurance, and claimants.

Return to work and associations with psychosocial well-being and health-related quality of life in coronary heart disease patients: Results from EUROASPIRE IV

Background

Coronary heart disease (CHD) can lead to loss of workability and early retirement. We aimed to investigate return to work (RTW) and its relationship towards psychosocial well-being and health-related quality of life (HRQoL).

Design

Secondary analyses were applied to cross-sectional data from the EUROASPIRE IV survey (European Action on Secondary and Primary prevention through Intervention to Reduce Events).

Methods

Participants were examined and interviewed at 6–36 months following the recruiting event. Psychosocial well-being and HRQoL were evaluated by completing the ‘Hospital Anxiety and Depression Scale’ and ‘HeartQoL’ questionnaire. Using generalised mixed models, we calculated the odds ratios for RTW. Depression, anxiety and adjusted means of HeartQoL were estimated accounting for RTW.

Results

Out of 3291 employed patients, the majority (76.0%) returned to work, of which 85.6% were men, but there was a general underrepresentation of women. Young ( p < 0.001), high-educated ( p < 0.001) patients without prior cardiovascular events ( p < 0.05) were better off regarding RTW. No significant associations with CHD risk factors and cardiac rehabilitation were established. Those that rejoined the workforce were less susceptible to psychosocial distress (anxiety/depression, p < 0.001) and experienced a better quality of life ( p < 0.001).

Conclusion

These findings provide evidence that non-modifiable factors (sociodemographic factors, cardiovascular history), more than classical risk factors, are associated with RTW, and that patients who resume work display better psychosocial well-being and HRQoL. Our results illustrate a need for tailored cardiac rehabilitation with a focus on work-related aspects, mental health and HRQoL indicators to reach sustainable RTW, especially in vulnerable groups like less educated and elderly patients.

Functional Capacity Evaluation in Different Societal Contexts: Results of a Multicountry Study

Purpose To examine factors associated with Functional Capacity Evaluation (FCE) results in patients with painful musculoskeletal conditions, with focus on social factors across multiple countries. Methods International cross-sectional study was performed within care as usual. Simple and multiple multilevel linear regression analyses which considered measurement's dependency within clinicians and country were conducted: FCE characteristics and biopsychosocial variables from patients and clinicians as independent variables; and FCE results (floor-to-waist lift, six-minute walk, and handgrip strength) as dependent variables. Results Data were collected for 372 patients, 54 clinicians, 18 facilities and 8 countries. Patients' height and reported pain intensity were consistently associated with every FCE result. Patients' sex, height, reported pain intensity, effort during FCE, social isolation, and disability, clinician's observed physical effort, and whether FCE test was prematurely ended were associated with lift. Patient's height, Body Mass Index, post-test heart-rate, reported pain intensity and effort during FCE, days off work, and whether FCE test was prematurely ended were associated with walk. Patient's age, sex, height, affected body area, reported pain intensity and catastrophizing, and physical work demands were associated with handgrip. Final regression models explained 38‒65% of total variance. Clinician and country random effects composed 1-39% of total residual variance in these models. Conclusion Biopsychosocial factors were associated with every FCE result across multiple countries; specifically, patients' height, reported pain intensity, clinician, and measurement country. Social factors, which had been under-researched, were consistently associated with FCE performances. Patients' FCE results should be considered from a biopsychosocial perspective, including different social contexts.

Implementing the ICF in Occupational Health; building a curriculum as an exemplary case

BACKGROUND

This paper addresses the need for a paradigm shift from post-diagnosis tertiary care towards maintenance and promotion of health across the lifespan, for healthcare in general and in occupational healthcare specifically. It is based on the assumption that the realization of this paradigm shift may be facilitated by teaching (future) occupational health professionals to use the International Classification of Functioning, Disability and Health (ICF).

OBJECTIVE

Describing the development of a an ICF based occupational health curriculum.

METHODS

Grafting a training trajectory in the ICF for educating the biopsychosocial health paradigm, onto a training trajectory in the Critical Appraisal of a Topic (CAT), a method for teaching evidence based practice skills.

RESULTS

The development process of the training trajectories in the master program Work, Health, and Career at Maastricht University is described as an example of an intervention for shifting the paradigm in healthcare curricula. The expected results are a shift from the biomedical towards the biopsychosocial paradigm, a reductionist approach towards a more holistic view on cases, a reactive way of working towards a more proactive work style, and from using a merely quantifiable evidence base towards using a broad evidence base.

CONCLUSIONS

Incorporating the biopsychosocial paradigm into the assessment and scientific reasoning skills of students is not only valuable in occupational healthcare but might be a valuable approach for all disciplines in healthcare for which contextual factors are important e.g. rehabilitation, psychiatry and nutritional science.

Fostering functioning of workers: A new challenge for prevention in occupational health

Given large changes in working conditions and society, occupational health care has to prioritize its efforts towards fostering health and functioning of workers and as such promote work participation. This requires that more emphasis is given on the application of biopsychological models in the care of workers. Although a biopsychological approach is often mentioned as essential part of occupational health care, it's application is often hampered in practice, by practical barriers and lack of practical knowledge. This is illustrated by a study that uncovered facilitating and hindering factors in the implementation process of a preventive strategy, proven effective in reducing the risk of long term sickness absence. To facilitate the use of biopsychological models in occupational health care, it is shown that setting up a training curriculum is possible, based on the International Classification of Functioning, Disability and Health (ICF) grafted on available training in evidence based practice skills is possible. Furthermore, there is a need for elaboration of the personal factors relevant for workers and the relevant work-related environmental factors to support practical application of ICF in occupational health care. A paradigm shift in occupational health care can facilitate widespread implementation of the biopsychosocial approach in occupational health and may stimulate occupational health professionals to further integrate this approach in their daily practice.

Experiences of occupational physicians with the implementation of indicated prevention for long term sickness absence

BACKGROUND

Functioning including work participation, is an emerging challenge in occupational health. The prevention of long term sickness absence (LTSA) through a strategy involving screening and structured early consultation (preventive strategy) was proven effective and can address participation issues. Implementation of this strategy has proven difficult.

OBJECTIVE

The aim of this study is to investigate the experiences of occupational physicians (OPs) delivering a structured early consultation to office workers, in order to enhance implementation of the strategy.

METHODS

In this case study, a mixed method design was used. Interviews and surveys were conducted to obtain an in-depth picture of OPs experiences.

RESULTS

Factors hindering implementation in relation to the OPs were difficulties in communicating the risk of future sick leave, prioritization of other tasks, maintaining a reactive approach due to work pressure, preference for prevention on the level of the work environment, privacy issues related to labeling workers to have mental or psychosocial issues, and the biomedical model being the mental model in use.

CONCLUSIONS

Implementation of the preventive strategy seems to require a more profound focus on the biopsychosocial approach. Training of relevant skills is important to achieve a focus on prevention and fostering health over the lifespan.
