BACKGROUND: Pain is affected by pain psychological factors (PPFs), whereas relationship between PPFs and job stress are unclear. OBJECTIVE: This study aimed to elucidate the relationship between PPFs and job stress in workers. METHODS:The study participants were the staff of the rehabilitation department of a core hospital. After undergoing a preliminary survey (38/43, 88% response rate), the rehabilitation workers were divided into the chronic pain group (CPG, n = 18) and the nonpain group (NPG, n = 13). RESULTS: Depression, anxiety, and magnification in the CPG were significantly associated with depressed mood and total stress response. Anxiety in the NPG was also significantly associated with all stress responses, except irritability and feelings of anxiety. Furthermore, all subscales of the Pain Catastrophizing Scale in the NPG were significantly and negatively associated with the vigor of stress responses. CONCLUSIONS: Chronic pain in workers was associated with severe job stress, and increased job stress worsened the state of chronic pain. Pain catastrophizing may be associated with early job stress in a person with no pain. This finding revealed a difference between the CPG and NPG and may be important for managing workers with job stress or pain.

With the innovation of healthcare delivery systems, a need for early determination of patients' discharge outcomes arises after proximal femur fracture surgery, to reduce the burden on healthcare infrastructure. Several studies have examined the extent of walking ability early in the postoperative period to predict the outcome destination. In this study, as an additional validation of these studies, we examined the effect of walking ability on the hospital discharge prognosis of patients in the first week after proximal femur fracture surgery in Japan. [Participants and Methods] Medical records of 228 patients with proximal femur fractures, aged ≥75 years old, admitted between April 2015 and March 2019, were retrospectively analyzed. The objective variable was discharge destination. The main evaluation factor was walking ability one-week post-surgery. [Results] Good walking ability and the company of a relative living together one week post-surgery were significant determining factors of discharge destination. [Conclusion] The ability to walk and the presence of a co-resident one week after surgery increased the likelihood of proximal femur fracture patients to be discharged directly to home. Our findings may help rehabilitation professionals make better decisions regarding discharge destination.

Background and Objectives: Pain affects psychological stress and general health in the working population. However, the factors affecting psychological job stress related to chronic pain are unclear. This study aimed to clarify the structural differences among factors affecting psychological job stress in workers with chronic pain and those without pain. Materials and Methods: A stepwise multiple regression analysis revealed the differences in structure between the psychological stress of workers with chronic pain and those with no pain. Psychological job stress by the Brief Job Stress Questionnaire was used as the dependent variable, with psychological state (depression and anxiety), specifically that characteristic of chronic pain (pain catastrophizing); information on the nature of the pain (intensity and duration); and number of years of service as independent variables. Selected independent variables were evaluated for collinearity. Results: In the model with psychological stress as a dependent variable (chronic pain: r2 = 0.57, F = 41.7, p < 0.0001; no-pain: r2 = 0.63, F = 26.3, p < 0.0001), the difference between the experiences of workers with chronic pain and those with no pain was that chronic pain was associated with depression (Beta = 0.43, p < 0.0001) and no pain with anxiety (Beta = 0.34, p < 0.0001). In the model with chronic pain-related depression as a dependent variable (r2 = 0.62, F = 41.7, p < 0.0001), job-life satisfaction (Beta = −0.18, p = 0.0017) and magnification (a dimension of pain catastrophizing; Beta = 0.16, p < 0.0001) were significant. Conclusions: The results of this study suggest that the psychological characteristics of chronic pain, such as depression and magnification, should be considered when evaluating and intervening in the job stress of workers with chronic pain.
