Servis sektöründe grup karar analizi yaklaşımı ile ergonomik risk değerlendirmesinin uygulaması

Risk assessment is important for prevention of occupational musculoskeletal system disorders (OMSD). Using of existing risk assessment methods in literature alone are not sufficient to identify work's risk level. Determining risk level of work using methods assessing one type risk doesn't give accurate and reliable results. The physical and psychosocial ergonomic risks are key factor in formation of OMSD. However, there isn't any research that integrates physical and psychosocial risks to assess them. Physical ergonomic risk assessment methods alone or psychosocial ergonomic risk assessment methods alone do not provide sufficient information on hazard dimensions of ergonomic risks. To determine risk level of work, firstly all risks affecting that work should be determined. It is very important to establish common evaluation according to identified risks and to determine risk level of work in terms of reliability of evaluation. The purpose of this study is to propose an integrated ergonomic risk assessment methodology (IERAMCA) by using outcomes of physical ergonomic risk assessment methods and psychosocial ergonomic risk assessment methods. These outcomes are weighted with multi-criteria decision analysis methods. Providing an integrated assessment and applying IERAMCA to obtain main causes of OMSD of laboratory staff in the blood center of a university hospital is aimed. The laboratory staff is likely to experience work-related musculoskeletal disorders due to the frequent occurrence of ergonomic risks in laboratory. According to results of study, works in laboratory is in medium risk group. According to this result, intervention recommendations have been developed.
