Design and Evaluation of an Interactive Individual Ergonomic Report for Surgeons

Abstract: Surgeons have been identified as one of the highest risk groups in healthcare to develop work-related musculoskeletal disorders (WMSDs). Especially the neck and shoulders are found to be at high musculoskeletal risk due to surgeons commonly operating in a static and awkward posture for a prolonged time. Raising ergonomic awareness has been found to favour postural improvement among healthcare professionals. This thesis therefore aimed to design and evaluate an individual ergonomic report as means for risk assessment and ergonomic education for surgeons. Hereby, two surgeons and two ergonomists were included in the design process for early user feedback. Thematic analysis was applied to analyse the user feedback and potential improvements were identified and performed. The final individual ergonomic report was evaluated as a material used in an individual educational session (i.e., the intervention group) and compared against the use of an ergonomic guideline (i.e., the control group). Each group consisted of two surgeons. Both questionnaire and semi-structured interview were used to evaluate the session. The results from the questionnaire showed similarly positive ratings on the user experience of both groups, but higher ratings were given on the perceived impact by the intervention group. The interview results also showed more positive responses by the intervention group in terms of the usability. Furthermore, facilitators and barriers for adopting ergonomic principles were collected from the surgeons. Multiple ways to improve surgical ergonomics as perceived by the surgeons were also identified, e.g., the use of ergonomic equipment, and implementation of stretch breaks in the OR. The results show the potential of an individual ergonomic assessment report as ergonomic intervention for surgeons to raise their awareness and knowledge about ergonomic principles which can contribute to decreasing their risk of developing WMSDs as well as improved surgical performance and patient safety. Future studies can regard further ergonomic risk parameters and incorporate practical instructions on ergonomic principles into educational ergonomic intervention.
