Objective To identify the determinants of direct cost caused by non-fatal occupational injury, and to provide evidence for the intervention strategy towards reducing the direct cost.
Methods A retrospective study of work-injured, suffered during the period between June 1st, 2004 and May 31st, 2008, in an electric locomotive enterprise in central China was employed. Employment information was retrieved from the company case reports, demographic and socio-economic data was interviewed by questionnaires, and medical information was retrieved from the affiliated hospital archival documents. Univariate analysis and multivariate liner regression model were used to examine the associations between potential determinants and direct cost.
Results Altogether 201 injured eventually entered the analysis, causing the total direct cost of 4 081 300 yuan Renminbi, in which the outpatient cost, inpatient cost and indirect medical cost were 41 100 yuan, 3 655 000 yuan, and 385 200 yuan Renminbi respectively. Injury nature, severity and locus affected direct cost in the univariate analyses. The multivariate analysis indicated that injury nature was significantly associated with outpatient cost, while hospital days, injury severity, marital status, injury nature and locus affected the inpatient cost directly or indirectly.
Conclusion Direct cost caused by non-fatal occupational injury was associated with multidimensional factors. Multi-sectional intervention strategy towards reducing direct cost should be developed.
