Kostnadseffektivitet för ergonomiska interventioner - Utvärdering av en beräkningsmodell (Swedish)
Abstract [en]

Several studies have shown that the work environment affects company performance. The managers are seldom aware to which extent work environment problems affect productivity, quality of delivery and sick-leave in their organisation. The present literature study showed that improvements regarding physical ergonomics generally are shown to be cost-effective. The most beneficial way of working is through proactive measures interactively with employees. An efficient, systematic way of performing risk assessments and interventions reduce the need for a calculation method. This study identified propositions for properties of calculation methods. These propositions were : “Simplicity, high usability”, “Right content for the target group”, “High ability to measure risk”, “Focus on staff”, “Correct standardised values”, “Right focus” and “Optimal design”. Scania CV, a producer of trucks and buses, has developed a calculation model for cost-effectiveness of ergonomic interventions. Evaluation of this model with semi-structured interviews showed agreement regarding the need of a simplified calculation method, based on systematic risk assessments.

Abstract [sv]

Ett flertal studier har visat att arbetsmiljön påverkar företags effektivitet. Företagsledningen är sällan medveten om till vilken grad arbetsmiljö-problem påverkar produktivitet, kvalitet och sjukfrånvaro. Litteraturstudien i detta projekt visade att förbättringar inom ergonomi generellt sett är kostnadseffektiva. Det är mest gynnsamt att arbeta proaktivt samt participativt, det vill säga i samarbete med medarbetarna på den lokala avdelningen. Ett effektivt, systematiskt arbete med riskbedömningar och interventioner minskar behovet av att göra en beräkning av lönsamheten. Propositioner för egenskaper hos kostnadseffektiva beräkningsmetoder togs fram i denna studie. Dessa propositioner var; ” Enkelhet och god användbarhet”, ”rätt innehåll för målgruppen”, ”hög förmåga att bedöma risk”, ”personalfokus”, ”korrekta standardiserade värden”, ”rätt fokus” och ”optimal design”. Scania CV, producent av lastbilar och bussar, har tagit fram en beräkningsmodell för kostnadseffektivitet hos ergonomiska interventioner. Utvärderingen av denna modell med semistrukturerade intervjuer visar god samstämmighet i att det behövs enkla kalkylmetoder som grundar sig på systematiska riskbedömningar.
