Abstract: Objective To study the biosafety protection of blood transfusion departments (blood banks) in all types of hospitals during the epidemic situation of Novel coronavirus pneumonia. Methods Through the "Internet + WeChat Questionnaire Star" platform, blood transfusion departments (blood banks) of 2 309 hospitals in all provinces and cities were surveyed except Hong Kong, Macao and Taiwan. Results 1 876 in 2 309 blood transfusion departments (blood bank)of hospitals had the function of external ventilation and lighting windows (81.25%), 1042 (45.13%) had secondary biosafety laboratories, 597(25.86%)equipped with biosafety cabinets and and 224 (9.7%) equipped with automatic centrifuges. 1 498(64.88%) in 2309 blood transfusion departments (blood bank) use materials with osmotic function in laboratory operating table. The employment rate of employees reaching Grade I biosafety protection products is 88.7%~95.8%, while the utilization rate of reaching Grade II biosafety protection products is only 23.45% -56.08%. After the test, 2 039 (88.31%)blood samples were covered with test tube covers and 2 000 (86.32%)sealed with two yellow garbage bags, and 1 229 (53.23%) of blood samples were stored for 7 days. Conclusion Through this Internet + investigation, we should realise that the work of biological safety protection in the blood transfusion department (blood bank) has a long way to go.
