Cost-effectiveness analysis of o-phthalaldehyde and glutaraldehyde as endoscope disinfectors / 中华消化内镜杂志

ABSTRACT

Objective To compare the durability and economic value of o-phthalaldehyde(OPA)and glutaraldehyde as endoscope disinfectors in continuous use of cleaning machine.Methods Compare the maximal number of endoseopes which could be disinfected by the two disinfectors at its minimal effective concentration,as well as the corresponding costs.The cost-effectiveness of two disinfectors were evaluated with Revenue-Incremental Cost Analysis.Results The number of endoscopes disinfected by OPA were 1.56 times as compared with glutaraldehyde,and an additional 2.95 yuan could be gained with OPA at the cost of 1 yuan.Conclusion When cleaning machine is full loaded,OPA is more durable than glutaraldehyde,and Can gain more benefit at the same cost.
