[New paths to interprofessional collaboration: collaboration between assistant practitioners and practice nurses in general and occupational health care]. / Nieuwe wegen naar arbocuratieve samenwerking: samen werken van praktijkondersteuners huis- en bedrijfsarts bij multiproblematiek.

Background: To this date, there is little to no interprofessional collaboration between professionals in general and occupational health care in the Netherlands. Where earlier initiatives for improvement focused on general practitioners (GPs) and occupational physicians (OPs), we examine the role that professionals working under task delegation of GPs and OPs can play in addressing problems on multiple life domains as well as in interprofessional collaboration.Methods: We conducted three focus group interviews with 7 assistant practitioners (APs) in general practice, 11 practice nurses (PNs) in general practice and 8 APs in occupational health practice.Results: All PNs and APs in our study are confronted with multi-domain problems and see a role for themselves in addressing these problems. Moreover, in case of multi-domain problems, they acknowledge the relevance of interprofessional collaboration to provide good care. At this moment, however, there is practically no collaboration at the level of PNs and APs. Challenges are found in the formal task delegation and role identity of the APs in occupational health practice, unfamiliarity and prejudices among especially general practice PNs and APs regarding occupational health care, and practical barriers as privacy laws and reachability.Conclusion: Interprofessional collaboration among PNs and APs in general and occupational health care is possible, provided that a solution is found for fundamental and practical challenges. Potential solutions are to shift the focus from sharing medical information to communicating about the needs of working patients to function healthily on multiple life domains, to address interprofessional collaboration in educations, to adapt consultation protocols to include work and to organize joint meetings between professionals in general and occupational health practice. Finally, addressing structural barriers such as privacy laws and financing requires political action.

Process evaluation of the 'Grip on Health' intervention in general and occupational health practice.

BACKGROUND: For working patients with a lower socioeconomic position, health complaints often result from a combination of problems on multiple life domains. To prevent long-term health complaints and absence from work, it is crucial for general and occupational health professionals to adopt a broad perspective on health and to collaborate when necessary. This study aimed to evaluate how the 'Grip on Health' intervention is implemented in general and occupational health practice to address multi-domain problems and to promote interprofessional collaboration. METHOD: A process evaluation was performed among 28 general and occupational health professionals, who were trained and implemented the Grip on Health intervention during a six-month period. The 'Measurement Instrument for Determinants of Innovations' was used to evaluate facilitators and barriers for implementing Grip on Health. Data included three group interviews with 17 professionals, a questionnaire and five individual interviews. RESULTS: While most health professionals were enthusiastic about the Grip on Health intervention, its implementation was hindered by contextual factors. Barriers in the socio-political context consisted of legal rules and regulations around sickness and disability, professional protocols for interprofessional collaboration, and the Covid-19 pandemic. On the organizational level, lack of consultation time was the main barrier. Facilitators were found on the level of the intervention and the health professional. For instance, professionals described how the intervention supports addressing multi-domain problems and has created awareness of work in each other's healthcare domain. They recognized the relevance of the intervention for a broad target group and experienced benefits of its use. The intervention period was, nevertheless, too short to determine the outcomes of Grip on Health. CONCLUSION: The Grip on Health intervention can be used to address problems on multiple life domains and to stimulate interprofessional collaboration. Visualizing multi-domain problems appeared especially helpful to guide patients with a lower socioeconomic position, and a joint training of general and occupational health professionals promoted their mutual awareness and familiarity. For a wider implementation, stakeholders on all levels, including the government and professional associations, should reflect on ways to address contextual barriers to promote a broad perspective on health as well as on collaborative work.

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

BACKGROUND: Many work-related items are not included in the current classification of environmental factors from the International Classification of Functioning, Disability and Health (ICF). Furthermore, personal factors are not classified and the ICF only provides a very limited list of examples. These facts make the ICF less useful for occupational health care and for research in the field of occupation and health. OBJECTIVE: The objective of this discussion paper is to introduce an elaboration of contextual factors, focussing on factors that influence work participation. METHODS: During the last 12 years, we developed two concept lists from the bottom up. These lists are based on our experiences in teaching and research, suggestions from students and other researchers, and factors found in the literature. In the fall of 2015 a scoping literature review was done to check for missing factors in these two concept lists. RESULTS: An elaboration of contextual factors, consisting of a list of work-related environmental factors and a list of personal factors. CONCLUSIONS: Important contextual factors that influence work participation are identified. Researchers, teachers, students, occupational and insurance physicians, allied health care professionals, employers, employees, and policy makers are invited to use the elaboration and to make suggestions for improvement. The elaboration and the suggestions received can be used in the ICF revision process. The development of an ICF ontology must be given priority, to give room to this elaboration, which will increase the applicability of the ICF and enable mapping with other terminologies and classifications.

Economic Evaluation of a Multifaceted Implementation Strategy for the Prevention of Hand Eczema Among Healthcare Workers in Comparison with a Control Group: The Hands4U Study.

The aim of this study was to evaluate the cost-effectiveness of a multifaceted implementation strategy for the prevention of hand eczema in comparison with a control group among healthcare workers. A total of 48 departments (n=1,649) were randomly allocated to the implementation strategy or the control group. Data on hand eczema and costs were collected at baseline and every 3 months. Cost-effectiveness analyses were performed using linear multilevel analyses. The probability of the implementation strategy being cost-effective gradually increased with an increasing willingness-to-pay, to 0.84 at a ceiling ratio of €590,000 per person with hand eczema prevented (societal perspective). The implementation strategy appeared to be not cost-effective in comparison with the control group (societal perspective), nor was it cost-beneficial to the employer. However, this study had some methodological problems which should be taken into account when interpreting the results.

Role models in a preventive program for hand eczema among healthcare workers: a qualitative exploration of their main tasks and associated barriers and facilitators.

BACKGROUND: Role models often play a role when implementing guidelines in healthcare. However, little is known about how role models perform their respective roles, or about which factors may hamper or enhance their functioning. The aim of the present study was therefore to investigate how role models perform there role as a part of a multifaceted implementation strategy on the prevention of hand eczema, and to identify barriers and facilitators for the performing of their role. METHODS: The role models were selected to become a role model and received a role model training. All role models worked at a hospital. In total, 19 role models, were interviewed. A topic list was used focussing on how the role models performed their role and what they experienced to be facilitators and barriers for their role. After coding the interviews, the codes were divided into themes. RESULTS: This study shows that the main tasks perceived by the role models were to raise awareness, to transfer information, to interact with colleagues about hand eczema, to provide material, and to perform coordinating tasks. Barriers and facilitators were whether the role suited the participant, affinity with the topic, and risk perception. CONCLUSIONS: Most role models performed only the tasks they learned during their training. They mentioned a wide range of barriers and facilitators for the performing of their role. To enhance the functioning of the role models, a suggestion would be to select role models by taking into account prior coaching experience. TRIAL REGISTRATION NUMBER: NTR2812.

Barriers and facilitators in the implementation of recommendations for hand eczema prevention among healthcare workers.

BACKGROUND: Evidence-based recommendations are available for the prevention of hand eczema among healthcare workers. However, the implementation of these recommendations is not always successful. OBJECTIVES: To identify barriers and facilitators in the implementation of recommendations for the prevention of hand eczema among healthcare workers alongside a randomized controlled trial. METHODS: A qualitative study was performed in which 19 healthcare workers were interviewed. The interview transcripts were open coded and also coded by means of a template by two researchers to identify relevant barriers and facilitators. RESULTS: Most barriers and facilitators reported for the recommendations were found at the level of the innovation (e.g. the recommendations), whereas for the guideline as a whole, multiple levels (socio-political, organization, user, and facilities) were identified. CONCLUSIONS: To enhance the implementation of recommendations for the prevention of hand eczema in a healthcare setting, having knowledge about these recommendations seems to be an important first step. In addition, maintaining the attention of the subject, testing the products beforehand and close collaboration with the infection control department might enhance implementation. Furthermore, it is important that the recommendations fit in with the work of the healthcare workers. When the implementation of the recommendations is prepared, these points should be taken into account.

Hands4U: the effects of a multifaceted implementation strategy on hand eczema prevalence in a healthcare setting. Results of a randomized controlled trial.

BACKGROUND: Healthcare workers have an increased risk of developing hand eczema. A multifaceted implementation strategy was developed to implement a guideline to prevent hand eczema among healthcare workers. OBJECTIVES: To investigate the effects of the implementation strategy on self-reported hand eczema and preventive behaviour. METHODS: A randomized controlled trial was performed. A total of 48 departments (n = 1649) were randomly allocated to the multifaceted implementation strategy or the control group. The strategy consisted of education, participatory working groups, and role models. Outcome measures were self-reported hand eczema and preventive behaviour. Data were collected at baseline, and 3, 6, 9 and 12 months of follow-up. RESULTS: Participants in the intervention group were significantly more likely to report hand eczema [odds ratio (OR) 1.45; 95% confidence interval (CI) 1.03-2.04], and they reported significantly less hand washing (B, - 0.38; 95%CI: - 0.48 to - 0.27), reported significantly more frequent use of a moisturizer (B, 0.30; 95%CI: 0.22-0.39) and were more likely to report wearing cotton undergloves (OR 6.33; 95%CI: 3.23-12.41) than participants in the control group 12 months after baseline. CONCLUSIONS: The strategy implemented can be used in practice, as it showed positive effects on preventive behaviour. More research is needed to investigate the unexpected effects on hand eczema.

Screening manual and office workers for risk of long-term sickness absence: cut-off points for the Work Ability Index.

OBJECTIVES: The aim of this study was to investigate the Work Ability Index (WAI) as a tool to screen for risk of different durations of long-term sickness absence (LTSA) among manual and office workers. METHODS: The prospective study comprised a cohort of 3049 (1710 manual and 1339 office) workers participating in occupational health surveys between 2010-2012. The survey date was set as baseline and incident LTSA episodes of different duration (>14, >28, >42, >60, and >90 days) were retrieved from an occupational health register in the year following the survey. Baseline WAI scores were associated with LTSA episodes occurring (no/yes) during one-year follow-up by logistic regression analysis in a random sample (N=1000) of the cohort. Predictions of LTSA risk were then validated among the workers not included in the random sample. RESULTS: The odds of LTSA episodes at follow-up decreased with increasing baseline WAI scores (ie, better work ability). The WAI accurately predicted the risk of future LTSA episodes >28, >42, >60 days, but over-predicted the risk of LTSA episodes >14 and >90 days. The WAI discriminated between workers at high and low risk of LTSA episodes of all durations. Office workers had higher WAI scores than manual workers. Consequently, false-negative rates were higher among office workers and false-positive rates were higher among manual workers at each WAI cut-off point. CONCLUSION: The WAI could be used to screen both manual and office workers for risk of LTSA episodes lasting >28, >42, >60 days. WAI cut-off points depend on the objectives of screening and may differ for manual and office workers.

Hands4U: the effectiveness of a multifaceted implementation strategy on behaviour related to the prevention of hand eczema-a randomised controlled trial among healthcare workers.

OBJECTIVES: To investigate the effects of a multifaceted implementation strategy on behaviour, behavioural determinants, knowledge and awareness of healthcare workers regarding the use of recommendations to prevent hand eczema. METHODS: The Hands4U study is a randomised controlled trial. A total of 48 departments (n=1649 workers) were randomly allocated to the multifaceted implementation strategy or the control group (minimal implementation strategy). Within the departments designated to the multifaceted implementation strategy, participatory working groups were set up to enhance the implementation of the recommendations for hand eczema. In addition, working group members were trained to become role models, and an education session was given within the department. Outcome measures were awareness, knowledge, receiving information, behaviour and behavioural determinants. Data were collected at baseline, with a 3- and 6-month follow-up. RESULTS: Statistically significant effects were found after 6 months for awareness (OR 6.30; 95% CI 3.41 to 11.63), knowledge (B 0.74; 95% CI 0.54 to 0.95), receiving information (OR 9.81; 95% CI 5.60 to 17.18), washing hands (B -0.40; 95% -0.51 to -0.29), use of moisturiser (B 0.29; 95% CI 0.20 to 0.38), cotton under gloves (OR 3.94; 95% CI 2.04 to 7.60) and the overall compliance measure (B 0.14; 95% CI 0.02 to 0.26), as a result of the multifaceted implementation strategy. No effects were found for behavioural determinants. CONCLUSIONS: The multifaceted implementation strategy can be used in healthcare settings to enhance the implementation of recommendations for the prevention of hand eczema. TRIAL REGISTRATION NUMBER: NTR2812.

Implementation of recommendations for hand eczema through a multifaceted strategy. A process evaluation among health care workers.

Process data give important insights into how an intervention is implemented. The aim of the present study is to conduct a process evaluation, alongside a randomised controlled trail, on the implementation of recommendations for the prevention of hand eczema. The intervention was carried out in healthcare workers' departments and consisted of working groups and role models. The role models were selected based on their representativeness, their influence on colleagues, and their motivation. The focus of the working group was to implement recommendations for hand eczema at the department by choosing solutions to overcome barriers for implementation. Out of the 104 solutions, 87 were realised. Solutions regarding moisturisers and use of cotton under gloves, were used by 90.9% and 30.8% of the employees, respectively. Of all participants, 58.2% actively engaged with the role models. This process evaluation showed that the intervention was executed according to protocol and that the solutions were implemented well. However, the role model component in the intervention should be improved.

Hand eczema among healthcare professionals in the Netherlands: prevalence, absenteeism, and presenteeism.

BACKGROUND: Healthcare professionals have a high risk of developing hand eczema. Hand eczema can interfere with their work. OBJECTIVES: To investigate the prevalence of self-reported hand eczema among healthcare professionals in the Netherlands, and to investigate absenteeism and presenteeism resulting from hand eczema. METHODS: A questionnaire-based observational study was performed. Participants were recruited from hospitals and nursing homes in the Netherlands. The study population consisted of 1232 healthcare professionals. We used the NOSQ-2002 to measure hand eczema and the PRODISQ for absenteeism and presenteeism. RESULTS: The 1-year prevalence of hand eczema among healthcare professionals was 12%. Among all participants, 47% reported symptoms related to hand eczema. Sick leave resulting from hand eczema was reported by 0.3% of healthcare professionals in general, and by 1.7% of healthcare professionals with hand eczema. In the group with hand eczema, 3.1% reported a large effect on presenteeism. CONCLUSIONS: The 1-year prevalence of hand eczema among healthcare professionals in the Netherlands is low, but the prevalence of symptoms related to hand eczema is quite high. Hand eczema seems to have little impact on work in terms of absenteeism and presenteeism.

Perceptions of mental workload in Dutch university employees of different ages: a focus group study.

BACKGROUND: As academic workload seems to be increasing, many studies examined factors that contribute to the mental workload of academics. Age-related differences in work motives and intellectual ability may lead to differences in experienced workload and in the way employees experience work features. This study aims to obtain a better understanding of age differences in sources of mental workload. 33 academics from one faculty discussed causes of workload during focus group interviews, stratified by age. FINDINGS: Among our participants, the influence of ageing seems most evident in employees' actions and reactions, while the causes of workload mentioned seemed largely similar. These individual reactions to workload may also be driven by differences in tenure. Most positively assessed work characteristics were: interaction with colleagues and students and autonomy. Aspects most often indicated as increasing the workload, were organisational aspects as obstacles for 'getting the best out of people' and the feeling that overtime seems unavoidable. Many employees indicated to feel stretched between the 'greediness' of the organisation and their own high working standards, and many fear to be assigned even less time for research if they do not meet the rigorous output criteria. Moreover, despite great efforts on their part, promotion opportunities seem limited. A more pronounced role for the supervisor seems appreciated by employees of all ages, although the specific interpretation varied between individuals and career stages. CONCLUSIONS: To preserve good working conditions and quality of work, it seems important to scrutinize the output requirements and tenure-based needs for employee supervision.

Age differences in the associations between sick leave and aspects of health, psychosocial workload and family life: a cross-sectional study.

OBJECTIVES: To investigate differences in associations between sick leave and aspects of health, psychosocial workload, family life and work-family interference between four age groups (<36, 36-45, 46-55 and 55+ years). DESIGN: A cross-sectional study; a questionnaire was sent to the home addresses of all employees of a university. SETTING: A Dutch university. PARTICIPANTS: 1843 employees returned the questionnaire (net response: 49.1%). The age distribution was as follows: <36: 32%; 36-45: 26%; 46-55: 27% and 55+: 12%. PRIMARY OUTCOMES: Frequent sick leave (FSL, ≥3 times in the past 12 months) and prolonged sick leave (PSL, >2 weeks in total in the past 12 months). Differences between the age groups in independent variables and outcomes were investigated. Logistic regression analysis was used to calculate associations between various variables and the sick leave outcomes. Interaction terms were included to detect differences between the age groups. RESULTS: Age differences were found for many work- and family-related characteristics but not in the mean scores for health-related aspects. Presence of chronic disease was reported more frequently with increasing age. The 55+ age group had almost two times less chance of FSL, but 1.6 times more chance of PSL than the <36 age group. Age moderates the associations between career opportunities, partner's contribution in domestic tasks and sex, and FSL. Job security and pay, support from supervisor, challenging work and being breadwinner have different associations with PSL. However, life events in private lives and perceived health complaints are important in all age groups. FSL and PSL have some determinants in common, but there are differences between the outcomes as well. CONCLUSIONS: Age should be treated as a variable of interest instead of a control variable. Employers and occupational physicians need to be aware that each phase in life has specific difficulties that can lead to FSL and PSL.

Using intervention mapping (IM) to develop a self-management programme for employees with a chronic disease in the Netherlands.

BACKGROUND: Employees with a chronic disease often encounter problems at work because of their chronic disease. The current paper describes the development of a self-management programme based on the Chronic Disease Self-Management programme (CDSMP) of Stanford University to help employees with a chronic somatic disease cope with these problems at work. The objective of this article is to present the systematic development and content of this programme. METHODS: The method of intervention mapping (Bartholomew 2006) was used to tailor the original CDSMP for employees with a chronic somatic disease. This paper describes the process of adjusting the CDSMP for this target group. A needs assessment has been carried out by a literature review and qualitative focus groups with employees with a chronic disease and involved health professionals. On the basis of the needs assessment, the relevant determinants of self-management behaviour at work have been identified for the target population and the objectives of the training have been formulated. Furthermore, techniques have been chosen to influence self-management and the determinants of behaviour and a programme plan has been developed. RESULTS: The intervention was designed to address general personal factors such as lifestyle, disease-related factors (for example coping with the disease) and work-related personal factors (such as self-efficacy at work). The course consists of six sessions of each two and a half hour and intents to increase the self management and empowerment of employees with a chronic somatic disease. CONCLUSION: Intervention mapping has been found to be a useful tool for tailoring in a systematic way the original CDSMP for employees with a chronic somatic disease. It might be valuable to use IM for the development or adjusting of interventions in occupational health care.

Work characteristics and determinants of job satisfaction in four age groups: university employees' point of view.

PURPOSE: To investigate (a) differences in work characteristics and (b) determinants of job satisfaction among employees in different age groups. METHODS: A cross-sectional questionnaire was filled in by 1,112 university employees, classified into four age groups. (a) Work characteristics were analysed with ANOVA while adjusting for sex and job classification. (b) Job satisfaction was regressed against job demands and job resources adapted from the Job Demands-Resources model. RESULTS: Statistically significant differences concerning work characteristics between age groups are present, but rather small. Regression analyses revealed that negative association of the job demands workload and conflicts at work with job satisfaction faded by adding job resources. Job resources were most correlated with more job satisfaction, especially more skill discretion and more relations with colleagues. CONCLUSIONS: Skill discretion and relations with colleagues are major determinants of job satisfaction. However, attention should also be given to conflicts at work, support from supervisor and opportunities for further education, because the mean scores of these work characteristics were disappointing in almost all age groups. The latter two characteristics were found to be associated significantly to job satisfaction in older workers.

Common prognostic factors of work disability among employees with a chronic somatic disease: a systematic review of cohort studies.

OBJECTIVE: Based on prospective and retrospective disease cohort studies, the aim of this review was to determine common prognostic factors for work disability among employees with rheumatoid arthritis, asthma, chronic obstructive pulmonary disease, diabetes mellitus, and ischemic heart disease (IHD). METHODS: A systematic literature search in Medline (1990-2008) and Embase (1990-2008) was carried out to identify relevant cohort studies using a well-defined list of inclusion and quality criteria. RESULTS: We identified 43 relevant cohort studies with sufficient methodological quality (20 for rheumatoid arthritis, 3 for asthma and 20 for IHD). The common prognostic factors for work disability found in all the diseases were: perceived health complaints, limitation in daily physical activities caused by the disease (high versus low), heavy manual work, and female gender. The common positive prognostic factors for rheumatoid arthritis and IHD were age (high versus low) and sickness absence. The common negative factors for rheumatoid arthritis and IHD were education (high versus low) and ethnic origin (white versus non-white). CONCLUSIONS: As many prognostic factors for work disability are similar for employees with various chronic diseases, it is possible to detect high risk groups. This information supports the development and implementation of a general disability management intervention for employees suffering from a chronic disease to overcome health-related limitations at work.

The role of illness perceptions in labor participation of the chronically ill.

OBJECTIVE: We aimed to investigate associations between work disability and illness perceptions, over and above medical assessment and self-reported health. METHODS: A representative sample of people aged 15-64 years with various chronic physical diseases was derived from the Panel of Patients with Chronic Diseases in the Netherlands. In this group, 189 patients were fully work-disabled and 363 were employed. In this cross-sectional study, associations between medical health status stated by the general practitioner, self-reported health, and illness perceptions about the consequences of the illness, the timeline (cyclical vs. chronical), control (treatment and personal), coherence and three causal dimensions (psychological, risk factors and immunity) and work disability were investigated. These associations were investigated in three separate steps using multivariate logistic regression analyses, with the employed patients as a reference group. All models were corrected for age, sex, and level of education. RESULTS: In the second multivariate model containing medical health status and self-perceived health, complete work disability was significantly associated with more fatigue (OR 2.42), more self-perceived functional limitations (OR 11.94), higher age, female sex, and lower education. Medical health status was not significantly associated with work disability. After adding illness perceptions to this model, the percentage of explained variance for work disability increased from 65 to 77%. In this final model, work disability was significantly associated with the patient's perception that the consequences of the disease were more severe (OR 5.34), and also with more self-perceived functional limitations (OR 14.27), lower education, being female, and a higher age. Illness perceptions and self-reported health status were significantly associated with work disability. CONCLUSION: We conclude that illness perceptions are significantly associated with work disability in the chronically ill. Self-reported health is more strongly associated with work disability than the assessment of health status by the physician.

Vocational and working career of asthmatic adolescents is only slightly affected.

INTRODUCTION: The aim of this study was to investigate whether teenagers and adolescents (10-22 years) with asthma or asymptomatic bronchial hyperresponsiveness, were more likely to experience vocational or professional career limitations in the future, as compared to non-asthmatic contemporaries. METHODS: Data were used from a 14-year follow-up study in general practice, investigating the relationship between respiratory health in childhood and adolescence. At follow-up, the respiratory health status and information about career limitations were obtained. RESULTS: There were no statistical significant differences between asthmatics (n=52) and non-asthmatics (n=154) in the proportion currently employed subjects, or contract type. Most examined career limitations were infrequently reported in both groups, but seemed to occur slightly more frequent among asthmatics. Asthmatics seemed to have an increased risk for limitations in daily activities both attributable to their respiratory health (OR=2.6, 95% CI [1.0; 7.0]) and all-cause (OR=1.8, 95% CI [0.9; 3.3]), and for absence from work all-cause (OR=1.7, 95% CI [0.9; 3.3]). However, the differences were in most cases in the magnitude of only a few days per year. Neither lung function nor bronchial hyperresponsiveness did predict absence from work, or limitations in daily activities. CONCLUSION: Asthmatic young adults seem to experience somewhat more limitations in their vocational and professional careers. Nonetheless, the majority of the young asthmatics seem to be only slightly limited in their careers. In non-asthmatic young adults the presence of asymptomatic bronchial hyperresponsiveness does not seem to lead to career limitations.

Knowledge about asthma and COPD: associations with sick leave, health complaints, functional limitations, adaptation, and perceived control.

We sought to investigate associations between knowledge about the disease and sick leave, health complaints, functional limitations, adaptation and perceived control. Patients with asthma (n = 101) and COPD (n = 64) underwent lung function tests and completed questionnaires. In addition, all were asked the question: 'what is the diagnosis of your disease?', with the response categories: 'asthma' and 'COPD (chronic bronchitis or emphysema)'. Thirty-five percent of the asthma patients and 30% of the COPD patients did not know their correct diagnosis. Sick leave was not associated with knowledge about the disease in asthma and COPD. In asthma, much knowledge about management of the disease was associated with better adaptation (P = 0.01) and less perceived control over health by external factors (P = 0.02). Knowing the correct diagnosis was associated with less control over health by powerful others (P = 0.02). For COPD, more knowledge about management of the disease was associated with better adaptation (P = 0.02) and less control over health by internal factors (P = 0.01). Knowing the correct diagnosis was associated with less control over dyspnea at work (P = 0.01).
