Arbetsmiljöekonomisk utvärdering av ergonomiförbättringar : Grundade i antaganden om sjukfrånvaro och förändring i arbetsbelastning efter intervention inom en avdelning i läkemedelsbranschen

Sammanfattning: The purpose of this study is to incrementally, through a combination of various methods, examine the assumptions about the working economic outcomes that can be made based on planned ergonomic intervention in a department at Pfizer Health AB in Strängnäs. The study contributes to knowledge about how assumptions on OSH financial results can be made, based on planned ergonomic interventions. These assumptions were based on biomechanical calculations made on the basis of ergonomics measurements with inclinometer. The study is important because previous research has shown that poor work environment have a bad impact on the economy of a company in different ways. It can for example be negative impact on the company's productivity and quality of the units produced or the services provided. Poor work environment can also contribute to increased absence due to illness. The study was conducted using three methods: 1) ergonomics measurement, 2) biomechanical calculations and 3) working economic analysis. To obtain documentation for the ergonomic measurements two inclinometers were used and attached to the arm and back at one long and one short test person. The biomechanical calculations were performed using a computer program called ALBA. The operations that were assumed to be most burdensome were calculated. Also an operation that remained unchanged after the intervention was calculated. That was made to give a better picture of how the workload would be after the intervention. The economic analysis was based largely from the assumption of sick leave due to heavy strenuous work. The calculation method used was "Remaining costs". The method helps to calculate the costs that the company had left when staff were absent from work. The study results showed that, through the assumption of one long-term illness every three years, it would be worth investing in ergonomic improvements for at least 4156 thousand kronor in C-Class (cost of occupational injuries + reduced product waste) with repayment in one year and four months. Compared to the cost of the planned interventions of 3150 thousand kronor it was assumed well worth implementing planned changes. The conclusion from the study was that the intervention could be recommended intended to reduce the workload and the repetitiveness of the employees.
