For healthcare personnel, the work environment is already challenging, and when eHealth systems are introduced they are often considered to further add to the complexity. This paper investigates the impact of patients' access to their electronic health records on healthcare professionals' work environment in a primary care setting in Sweden. A work environment theory-driven analysis, focusing on perceived demands, control and support, was conducted on 14 semi-structured interviews of different primary care professionals. The professionals expressed a slight increase in demands, loss of control and some increase and decrease of support. This study discusses insights on how patients' access to health records can have an impact on healthcare professionals' work environment.
