Evaluating the fit of operating theatre tables – using basic ergonomics to help improve procurement of medical technology.

Abstract

This paper discusses an appraisal of the fit of operating theatre tables to the surgical staff who have to use them. In total 55 tables were evaluated in 70 configurations. By identifying the ethnic profile of the surgical population, appropriate anthropometric data was obtained which provided a user-centred focus for the evaluation. Using basic dimensional data the range of adjustment of the height of each table was scrutinised to see if it was appropriate to accommodate the needs of the user in terms of reach for open and laparoscopic surgery as well as sight lines. It was found that the majority of tables failed to provide adequate adjustment to accommodate the needs of the users, with smaller users suffering the poorest fit. By converting the data comparison to a simple star rating scheme, a relatively complex ergonomic investigation could be made readily available to procurement professionals and help guide them into appropriate choices to enable them to secure best value in equipment selection and help prevent ongoing occupational ill health.
