Abstract：Objective To explore the application effect of"three-step hand-washing method"in process of blood collection in department of clinical laboratory.Methods Forty medical staff from department of clinical laboratory of a tertiary hospital in Longyan from September 2023 to April 2024 were selected as research subjects.Taking the implementation time of"three-step hand-washing method"(January 2024)as time node,"six-step hand-washing method"was implemented in medical staff before implementation(September to December 2023),and"three-step hand-washing method"was adopted after implementation(January to April 2024).The disinfection effect,compliance and accuracy of hand hygiene methods in medical staff before and after implementation of"three-step hand-washing method"were compared.Results There was no significant difference in the disinfection pass rate before and after implementation(87.50%vs.92.50%,P>0.05).At four hand hygiene moments such as before contacting patients,before cleaning/aseptic operations,after contacting patients and after contacting patient environments,the hand hygiene compliance after implementation was significantly higher than that before implementation(before contacting patients:62.79%vs.43.19%;before cleaning/aseptic operations:60.74%vs.39.38%;after contacting patients:70.07%vs.60.09%;after contacting patient environments:73.70%vs.27.74%;all P<0.05).However,there was no significant difference in hand hygiene compliance after liquid contact before and after implementation(81.48%vs.66.67%,P>0.05).The hand hygiene accuracy after implementation was significantly higher than that before implementation(95.20%vs.79.66%,P<0.05).Conclusion Compared with"six-step hand-washing method","three-step hand-washing method"could improve hand hygiene compliance and accuracy in the blood collection process while ensuring disinfection effectiveness.
