Abstract

Background: Our aim was to make right and informative decision about choosing the most cost-effectiveness heter-ogeneous infectious waste treatment methods and devices. Methods: In this descriptive study, decision tree analysis, with 10-yr time horizon in bottom-up approach was used to estimate the costs and effectiveness criteria of the employed devices at provider perspective in Iranian hospitals. We used the one-way and scenario sensitivity analysis to measure the effects of variables with uncertainty. The resources of data were national Environmental and Occupational Health Center Survey (EOHCS) in 2012, field observation and completing questionnaire by relevant authorities in mentioned centers. Results: Devices called Saray 2, Autoclave based, and Newster 10, Hydroclave based, with 92032.4 () and 6786322.9 () Dollars had the lowest and highest costs respectively in studied time period and given the 5-10% discount rate. Depending on effectiveness factor type, Newster 10 with Ecodas products and Saray products re-spectively had the highest and lowest effectiveness. In most considered scenarios, Caspian-Alborz device was the most cost-effectiveness alternative, so for the treatment of each adjusted unit of volume and weight of infectious waste in a 10 year period and in different conditions, between 39.4 () to 915 () dollars must be spent. Conclusion: The findings indicate the inefficiency and waste of resources, so in order to efficient resource allocation and to encourage further cost containment in infectious waste management we introduce policy recommendation that be taken in three levels. © 2015 Iran J Public Health All Right reserved.
