Objectives: Increasing sickness absence (SA) has been reported among healthcare workers in Sweden. Our aim was to analyse the impact of work environment factors on short-term and long-term SA based on musculoskeletal and psychiatric diagnoses among healthcare workers.
Methods: The study sample consisted of healthcare workers (n=12 452) drawn from representative samples of workers aged 16 to 64, who participated in the Swedish Work Environment Surveys (SWES) between 1993 and 2013. The outcomes were either short-term (≤28 days) or long-term (>104 days) SA between 1994 and 2016. HRs and 95% CIs were calculated for the impact of physical and psychosocial working conditions on risk of subsequent short-term or long-term SA for 3 years after participation in SWES.
Results: Heavy physical work and strenuous work postures showed elevated HRs for short-term and long-term SA compared with those without these work exposures. Similarly, high job demands and low job control each increased the risk for both short-term and long-term SA compared with employees with low job demands and high job control. Low job support increased the risk for short-term SA compared with those with high job support. Working conditions were strongly related to short-term SA due to musculoskeletal diagnoses but not to short-term SA due to psychiatric diagnoses. None of the work characteristics, except strenuous postures, elevated the risk for long-term SA due to psychiatric diagnosis compared with employees without these characteristics.
Conclusions: Ergonomic improvements and stress reduction among healthcare workers are likely to reduce the prevalence of SA foremost due to musculoskeletal diagnoses.
