Effort-reward imbalance and its association with sociocultural diversity factors at work: findings from a cross-sectional survey among physicians and nurses in Germany.

Objective: Due to staff shortages and reports of high work stress, work conditions of hospital physicians and nurses receive wide attention. Additionally, sociocultural diversity of the workforce and patient population is increasing. Our study aim is to analyze how individual and organizational diversity-related factors are associated with the experience of staff's work stress.

Methods: A cross-sectional online survey was conducted with healthcare staff from 22 acute hospitals operated by two healthcare organizations in Germany in 2018. Sociodemographic, occupational and organizational factors were surveyed. Participants further reported work conditions related to the sociocultural diversity of colleagues and patients. Effort-reward imbalance (ERI) was measured with the German short version. Multivariable regression models were calculated with ER ratio as an outcome.

Results: N = 800 healthcare staff were included. Variables associated with higher ERI were longer work experience (β = 0.092, p < 0.05), not holding a leading position (0.122, < 0.01), being a witness (0.149, < 0.001) or victim (0.099, < 0.05) of discrimination at one's own ward, reporting frequent burden due to language barriers with patients (0.102, < 0.01) and colleagues (0.127, < 0.001), and having restricted access to translators at work (0.175, < 0.001). Factors associated with lower ERI were having a first generation migration background (- 0.095, < 0.05) and being a physician (- 0.112, < 0.05).

Conclusions: Catering to the needs of healthcare personnel in dealing with the additional effort related to language barriers at work, e.g., readily available translator services, and creating non-discriminatory work environments might be one cornerstone for the prevention of work-related ill health and retention of qualified hospital staff.
