Cost benefits of ergonomic intervention in a hospital: a preliminary study using Oxenburgh's productivity model

This case study of absenteeism amongst nurses was carried out using the productivity model of Oxenburgh (1991). Data on absenteeism amongst nurses were collected from one private hospital. Areas of high risk of injury were identified and the presence of ergonomic risk factors determined. The productivity model was used to calculate the costs of absenteeism in terms of actual rates of pay and loss of productivity. Potential benefits resulting from ergonomic improvements to the work environment were estimated using the productivity model. The model predicted that even modest reductions in injury would justify the additional expenditure in a relatively short period of time. Further investigations of injuries to nurses in both State and Private Sector Hospitals seem to be justified.
