Introduction: Today, the infectious wastes of hospitals are considered as a public health problem. Considering the huge amounts of hazardous wastes and the disadvantages of incinerators, we need to investigate the non-combustible devices involved in biochemical treatment. This study was carried out with the aim of evaluating the cost-effectiveness of infectious wastes devices.
Materials and Methods: This descriptive-analytical study was conducted to evaluate the cost-effectiveness and economic efficiency of the infectious waste devices in Yazd and Isfahan hospitals.  In this study, the total cost of infectious waste treatment systems in hospitals, the Incremental Cost Effectiveness Ratio (ICER), as well as the sensitivity rate for the reduction of infectious wastes were calculated using Treeage software version 2011. In order to calculate the cost effectiveness using the total cost and the amount of produced waste, we applied the discount rate of five percent and the useful life of 10 years for each device.
Results: Based on the results, devices A and F had the highest and the lowest total cost, respectively. In addition, autoclave D with an ICER of 257.20 was more cost effective than other devices. So, device D, with a discount rate of ±5 and a range of 244.244 - 270.06 was chosen as the best option for infectious waste disposal.
Conclusion: The results can be used to explore and outline the future prospects for choosing the best technology for treatment of infectious waste in hospitals. In other words, we have different options on different circumstances and occasions.
