Abstract
Background: workers are at high risk for developing mental health complaints due to frequent exposure to risk factors such as high work demands, low work control and high emotional demands. Aim: To be able to plan a job-specific workers’ health surveillance (WHS) program properly, knowledge about the number of workers that could be expected to be the target for interventions should be known. Therefore we studied the prevalence of stress and common mental health complaints among Dutch healthcare workers for the disabled who voluntarily participated in WHS in a large healthcare organization.
Methods: In total, 615 workers positively responded to the invitation for the surveillance program; 449 workers were willing to participate in the research study by giving informed consent. We used validated scales to assess general stress, work-related fatigue, distress, burnout, and posttraumatic stress. The prevalence rate of each mental health complaint was calculated.
Results: Information from 402 workers was eligible for analysis (response rate 65%). The mental health prevalence rates were: general 22%, work-related fatigue 17%, distress 12%, burnout 6%, post-traumatic stress complaints 8%.
Conclusions: Common mental health complaints among healthcare workers of the disabled is common (one in every five workers) for general stress and work-related fatigue. Distress was found in about 10% of the workers. Burnout and post-traumatic stress was less common (1 in 19-20 workers). This study suggests that to ensure future workers’ health and quality of care, employers of healthcare workers of the disabled should be offered WHS with adequate intervention strategies periodically.

Healthcare workers are at high risk for developing occupational mental health complaints due to frequent exposure to risk factors such as high work demands, low work control and high emotional demands [1]. Exposure to these risk factors may increase the chance of experiencing stress complaints and other mental health complaints. Mental health complaints can affect work performance. This was shown in a study on hospital physicians [2]. These complaints also influence other aspects such as the quality of interaction with patients and colleagues [3]. To keep healthcare availability at the desired level, it is important to keep workers healthy in their job and to prevent ill health or absenteeism. It is known that moderate and high psychological distress increases the odds for workplace failure and decreases the odds for workplace success [4]. Efforts to prevent workrelated health problems usually target employees who already show a certain degree of impairment of health or work functioning. With a Workers’ Health Surveillance (WHS) program we can focus more on early detection of impaired health to prevent a loss in work functioning. To be able to plan a job-specific WHS properly, knowledge about the number of workers that could be expected to be target for interventions should be known. We therefore studied the prevalence of stress and common mental health complaints among Dutch healthcare workers for the disabled from a large healthcare organization during a pilot WHS.
Method
A cross-sectional study was performed in 2015 in a Dutch healthcare organization for the disabled of 7,600 employees. Study subjects were recruited by opportunity (voluntary response) sampling. About one third of the total population was invited to participate in a voluntary WHS. Workers who were interested in WHS (N=615) were contacted. This is the source population for the study. The employees worked either as an attendant, assistant-attendant or domestic worker. Official approval by the Medical Ethics Review Committee of the AMC was not required. General stress complaints and work-related fatigue were assessed by the Need for Recovery after Work scale and the Depression Anxiety Stress Scale (DASS). The Need for Recovery after work scale is the work-related fatigue scale and part of the Dutch Experience and Evaluation of Work Questionnaire (Dutch: VBBA) [5,6]. The scale measures the extent to which employees experience problems in recovery efforts from work. The scale score is calculated by adding the individual's scores on the eleven (recoded) yes/no items. This scale score is transformed into a scale ranging from 0 to 100. Higher scores (>54.4) indicate a high degree of need for recovery after work. Stress was assessed by the Depression Anxiety Stress Scale (DASS-21) [7]. This scale contains 13 theses about stress with the response categories “never (0),” “sometimes (1),” “often (2),” “mostly (3),” and “always (4)”. A scale score of 10 points or higher can be regarded as a high level of general stress. The first of the specific mental health screeners was the distress-screener [8]. This scale has three items about the worker’s feeling in previous week with a four point Likert scale of “no (0),” “sometimes (1),” “regular (2)” and “often (2)” A summed score of 4 points or more means an indication for adjustment disorder. Burnout was assessed through its two key dimensions: emotional exhaustion and cynicism [9,10]. Emotional exhaustion (5 items) is marked by a general feeling of extreme chronic fatigue caused by continuous or prolonged exposure to harsh working conditions. Cynicism (4 items) is defined as a hardened and cynical attitude to the work and/or persons with whom one works. Both scales consist of items with the response categories “never”(0), “almost never” (1), “sometimes” (2), “regular” (3), “often” (4), “very often” (5) and “always” (6). A summed mean score of 2,2 on emotional exhaustion and 2,0 on cynicism was used as indication for burnout. The last screener is the Dutch version of the “Impact of Event” scale, a screener of Post-Traumatic Stress. It consists of 15 theses with the response categories “not at all (0),” “rarely (1),” “sometimes (3),” and “often (5).” A scale score over 26 points means an indication of PTSD [11].
Results
In total, 615 workers positively responded to the invitation for the WHS program; A total of 449 workers were willing to participate in the research study by giving informed consent. Of these, 402 participants (65% of all positive responders) completed the questionnaires completely. A flowchart is presented in Figure 1.

Discussion
Mental health complaints among healthcare workers of the disabled that participated in a WHS program are common (about one in every five workers) for general stress and work-related fatigue. Distress was found in 12% and burnout and post-traumatic stress was less common (1 in 19-20 workers). In the Mental Vitality @ Work study, Ketelaar et al. [12] studied in a randomized controlled trial the effects of an Emental health intervention in a WHS program on mental health of hospital nurses and allied health professionals of a large hospital. By using the same questionnaires and cut-off points, they found slightly higher prevalence of mental health complaints among WHS participants in their baseline population: distress 24%, work-related fatigue 34% and PTSS 12%. The authors in that study aimed for high sensitivity, since they did not want to miss participants who might need help. In a cross-sectional study among professionals (most nurses) linked to the primary healthcare network in the city of Aracaju, Brasil, the prevalence of high risk of burnout (7%) showed findings comparable with our results [13]. However, study participants in that study were merely restricted to higher education professionals and the sampling was not related to WHS.
Mental health complaints seem to be a prevalent problem in healthcare workers of the disabled which can be seen as an opportunity to start a preventive program. The more so because screening on health issues with a higher prevalence theoretically increases the positive predictive value of the outcome. This enables an effective referral to adequate interventions in this population. Moreover, knowing the prevalence estimates gives an indication how many mental health interventions should be planned for. We did not perform a nonresponse study among the 35% of the workers that did not respond (completely) after they had indicated their interest in the WHS program. Analysis showed no differences in sexes and age between responders and non-responders. However, taking into account the low response rate to the initial invitation for WHS, future strategies to increase the attendance rate are needed. When we compare the response to the invitation for a voluntary WHS with other WHS programs in healthcare employees, our response is substantially lower [14-16]. A reason for this might be the reorganization that took place in the healthcare organization with a job loss of 10 percent of all employees.
