WS / t313-2009 code for hand hygiene of medical personnel does not require the opening date of hand sanitizer after opening. It will undoubtedly increase the workload for nurses to indicate the opening time. However, from the perspective of management, it is not too bad to indicate the opening date. The hand sanitizer may be polluted in the use process, such as the pollution caused by the siphon effect after pressing; the improper position of the hand sanitizer, the liquid splashing pollution of the liquid outlet when washing hands; the medical staff are used to wipe the liquid outlet with their hands after taking the liquid; self adding or diluting the hand sanitizer, etc. Xiao Lihua and Chen Yuqin confirmed in the research that the antibacterial hand sanitizer used in medical institutions is seriously polluted by microorganisms, and the longer it is used, the more seriously it is polluted. The samples with the total number of bacteria more than 1000 CFU / g of antibacterial hand sanitizer are mostly from the outpatient department or auxiliary department after opening for more than 60 days. For some reasons, when the hand hygiene compliance is poor, it is beneficial to mark the opening date after the hand sanitizer is opened as a management method. It can not only indirectly understand the hand sanitizer compliance of medical personnel, but also find out the hand sanitizer that has not been used up for a long time, so as to change it in time.

 

Since the service life after opening has no reference basis in national standards, industry and local laws and regulations, as well as documentary evidences, the service life after opening needs further study. When the liquid appears discoloration, suspended matter or precipitation, stratification, turbidity and peculiar smell, it must be replaced.

 

In the Department with high hand washing compliance, there is usually no problem of too long opening time of hand sanitizer. There is no need to face the confusion of whether to indicate the opening date. For departments with low hand and hand compliance, strengthening hand and hand compliance is the fundamental way to solve the problem. In addition, for some hand sanitizers in places with small workload or infrequently used, small package products can be considered
