Risk Assessment of Physical Hazards in Greek Hospitals Combining Staff's Perception, Experts ' Evaluation and Objective Measurements

Objectives: The promotion of health and safety (H&S) awareness among hospital staff can be applied through various methods. The aim of this study was to assess the risk level of physical hazards in the hospital sector by combining workers ’ perception, ex-perts ’ evaluation and objective measurements. Methods: A crosssectional study was designed using multiple triangulation. Hospital staff (n = 447) filled in an H&S question-naire in a general hospital in Athens and an oncology one in Thessaloniki. Experts observed and filled in a checklist on H&S in the various departments of the two hospitals. Lighting, noise and microclimate measurements were performed. Results: The staff’s perception of risk was higher than that of the experts in many cases. The measured risk levels were low to medium. In cases of highrisk noise and lighting, staff and experts agreed. Staff’s perception of risk was influenced by hospital’s department, hospital’s service, years of working experience and level of education. Therefore, these factors should be taken into account in future studies aimed at increasing the participation of hospital workers. Conclusion: This study confirmed the usefulness of staff participation in the risk assessment process, despite the tendency for staff to overestimate the risk level of physical hazards. The combination of combining staff perception, experts ’ evaluation an
