Empowering employees with chronic diseases: process evaluation of an intervention aimed at job retention

Purpose Employees with a chronic disease may experience work-related problems that contribute to the risk of job loss. We developed a group-based intervention programme aimed at clarifying problems, making these a subject of discussion at work, and realizing solutions. This process evaluation investigates the intervention's feasibility and the satisfaction of 64 participants in eight groups. Methods Data were collected through process evaluation forms and self-report questionnaires. Results The recruitment of participants was time-consuming. Highly educated women working in the service sector were overrepresented. The programme was administered as planned, although components were sometimes only discussed briefly, due to lack of time. Satisfaction with the overall programme among participants was high; it was perceived as effective and there were only three dropouts. In particular, the focus on feelings and thoughts about having a chronic disease was highly valued, as were the exchange of experiences and role-playing directed at more assertive communication. Conclusions A vocational rehabilitation programme aimed at job retention is feasible and is perceived to be effective. Such a programme should address psychosocial aspects of working with a chronic disease beside practical problems. The recruitment of participants is time-consuming. Cooperation with outpatient clinics is necessary in order to reach all groups of employees with a chronic disease that might benefit from job retention programmes. Trial registration: ISRCTN77240155

Behavioral determinants as predictors of return to work after long-term sickness absence: an application of the theory of planned behavior

Background The aim of this prospective, longitudinal cohort study was to analyze the association between the three behavioral determinants of the theory of planned behavior (TPB) model-attitude, subjective norm and self-efficacy-and the time to return-to-work (RTW) in employees on long-term sick leave. Methods The study was based on a sample of 926 employees on sickness absence (maximum duration of 12 weeks). The employees filled out a baseline questionnaire and were subsequently followed until the tenth month after listing sick. The TPB-determinants were measured at baseline. Work attitude was measured with a Dutch language version of the Work Involvement Scale. Subjective norm was measured with a self-structured scale reflecting a person's perception of social support and social pressure. Self-efficacy was measured with the three subscales of a standardised Dutch version of the general self-efficacy scale (ALCOS): willingness to expend effort in completing the behavior, persistence in the face of adversity, and willingness to initiate behavior. Cox proportional hazards regression analyses were used to identify behavioral determinants of the time to RTW. Results Median time to RTW was 160 days. In the univariate analysis, all potential prognostic factors were significantly associated (P < 0.15) with time to RTW: work attitude, social support, and the three subscales of self-efficacy. The final multivariate model with time to RTW as the predicted outcome included work attitude, social support and willingness to expend effort in completing the behavior as significant predictive factors. Conclusions This prospective, longitudinal cohort-study showed that work attitude, social support and willingness to expend effort in completing the behavior are significantly associated with a shorter time to RTW in employees on long-term sickness absence. This provides suggestive evidence for the relevance of behavioral characteristics in the prediction of duration of sickness absence. It may be a promising approach to address the behavioral determinants in the development of interventions focusing on RTW in employees on long-term sick leave

Reliability and Validity of the Disability Assessment Structured Interview (DASI): A Tool for Assessing Functional Limitations in Claimants

Objective The aim of this study is to investigate the reliability and validity of the Disability Assessment Structured Interview (DASI). The DASI is a semi-structured interview for assessing long-term functional limitations concerning the work disability assessment of claimants. Methods A randomized controlled trial was conducted. Patients applying for a work-disability pension after 21 months of sick leave were independently interviewed and examined either by two physicians who had completed a DASI training period (n = 32) or by two physicians from a control group (n = 30) without any DASI training. Agreement percentages within both groups of physicians, eligibility for a disability benefit, and differences between the groups in terms of the scores given on the work-limitation items from the Functional Ability List (FAL) were measured to investigate reliability and concurrent validity. To determine the content validity, the insurance physicians who completed DASI training (n = 8) were asked to fill out a questionnaire concerning their opinion of the DASI. Additionally, patients filled out a questionnaire to measure their satisfaction as to the behavioral aspects of the physicians. Results The groups showed no important differences in agreement percentages (mean percentage about 80%) and eligibility for a disability benefit. In 9 out of 21 items the physicians of the control group indicated fewer work limitations compared to physicians using the DASI. All physicians agreed on the fact that the DASI was an acceptable tool in daily practice, one that provided a realistic picture of the patient and provided sufficient information to assess functional limitations. In addition, between the two groups, no differences were found as to the satisfaction of patients concerning the behavioral aspects of the physicians. Conclusion The DASI is a tool with a reasonable to good inter-rater reliability and content validity, and it appears to be acceptable to both patients and physicians. It did not improve inter-observer agreement beyond that of usual interview procedures used in the Netherlands. The DASI would seem to be a worthwhile tool for collecting self-reported information in order to assess functional limitations in claimants

Sick-listed employees with severe medically unexplained physical symptoms: burden or routine for the occupational health physician? A cross sectional study

Background: The two primary objectives of this study were to the assess consultation load of occupational health physicians (OHPs), and their difficulties and needs with regard to their sickness certification tasks in sick-listed employees with severe medical unexplained physical symptoms (MUPS). Third objective was to determine which disease-, patient-, doctor- and practice-related factors are associated with the difficulties and needs of the OHPs. Methods: In this cross-sectional study, 43 participating OHPs from 5 group practices assessed 489 sick-listed employees with and without severe MUPS. The OHPs filled in a questionnaire about difficulties concerning sickness certification tasks, consultation time, their needs with regard to consultation with or referral to a psychiatrist or psychologist, and communication with GPs. The OHPs also completed a questionnaire about their personal characteristics. Results: OHPs only experienced task difficulties in employees with severe MUPS in relation to their communication with the treating physician. This only occured in cases in which the OHP attributed the physical symptoms to somatoform causes. If they attributed the physical symptoms to mental causes, the OHPs reported a need to consultate a psychiatrist about the diagnosis and treatment. Conclusions: OHPs experience few difficulties with their sickness certification tasks and consultation load concerning employees with severe MUPS. However, they encounter problems if the diagnostic uncertainties of the treating physician interfere with the return to work process. OHPs have a need for psychiatric expertise whenever they are uncertain about the psychiatric causes of a delayed return to work process. We recommend further training programs for OHPs. They should also have more opportunity for consultation and referral to a psychiatrist, and their communication with treating physicians should be improved

The Contribution of High Levels of Somatic Symptom Severity to Sickness Absence Duration, Disability and Discharge

Introduction: The primary objectives were to compare the duration of sickness absence in employees with high levels of somatic symptom severity (HLSSS) with employees with lower levels of somatic symptom severity, and to establish the long-term outcomes concerning return to work (RTW), disability and discharge. Secondary objective was to evaluate determinants of the duration of sickness absence in employees with HLSSS. Methods: 489 sick-listed employees registered with five Occupational Health Physician (OHP) group practices were included in this study. We measured their baseline scores for somatic symptoms severity, depressive disorders, anxiety disorders, health anxiety, distress and functional impairment. The OHPs filled in a questionnaire on their diagnosis. A prospective 2-year follow-up was carried out to assess the long-term outcomes concerning sickness absence, and retrospective information was gathered with regard to sickness absence during the 12 months before the employees were sick-listed. Results: The median duration of sickness absence was 78 days longer for employees with HLSSS. They more often remained disabled and were discharged more often, especially due to problems in the relationship between the employer and the employee. HLSSS, health anxiety and older age contributed to a longer duration of sickness absence of employees. Conclusion: High levels of somatic symptom severity are a determinant of prolonged sickness absence, enduring disabilities and health-related job loss. Occupational health physicians should identify employees who are at risk and adhere to guidelines for medically unexplained somatic symptoms

Severe MUPS in a sick-listed population: a cross-sectional study on prevalence, recognition, psychiatric co-morbidity and impairment

Background: Medically unexplained physical symptoms (MUPS) have a high prevalence in the general population and are associated with psychiatric morbidity. There are indications that MUPS are an important determinant of frequent and long-term disability. The primary objective was to assess the prevalence of MUPS in sick-listed-employees and its associations with depressive disorders, anxiety disorders, health anxiety, distress and functional impairment. Secondary objectives were to investigate the classification of the occupational health physicians (OHPs), their opinions about the causes as well as the attributions of the employee. Methods: In a cross- sectional study of 489 sick-listed employees from 5 OHP group practices, MUPS, depressive disorders, anxiety disorders, health anxiety, distress and functional impairment were assessed with the Patient Health Questionnaire (PHQ), the Whitely Index (WI), the Four-Dimensional Symptom Questionnaire (4DSQ) and the Short-Form 36 Health Survey (SF-36). We used a cut off score of 15 on the PHQ for the categorisation of severe MUPS. The opinions of the OHPs were evaluated by means of a separate questionnaire with regard to the presence of employees physical symptoms, and the symptoms attributions, and the diagnoses of the OHPs. Results: Severe MUPS had a prevalence of 15.1% in this population of sick-listed employees. These employees had 4-6 times more depressive and anxiety disorders, and were more impaired. Female gender and PHQ-9 scores were determinants of severe MUPS. Most of the time the OHPs diagnosed employees with severe MUPS as having a mental disorder. The employees attributed their physical symptoms in 66% to mental or to both mental and physical causes. Conclusion: The prevalence of severe MUPS is higher in long-term sick-listed employees than in the non-sick-listed working population and at least equals the prevalence in the general practice population. Severe MUPS are associated with psychiatric morbidity and functional impairment and must therefore be specifically recognised as such. Validated questionnaires, such as the PHQ-15, are useful instruments in order to help OHPs to recognise severe MUPS
