ABSTRACT

【Objective】 To retrospectively analyze the reasons of insufficient blood collected, to provide evidences for further taking targeted measures, to reduce the discard of insufficient whole blood and prevent the loss of blood donors. 【Methods】 Calculate the total number of whole blood donors and the number of whole blood donors donating insufficient blood during 2018~2020 annually in Guangzhou Blood Center Information System, and the data was analyzed in SPSS (22.0) software for χ2test and linear trend test. 【Results】 During 2018~2020, the incidence of insufficient blood collected was 0.066 4%(531/799 439), and the incidence of insufficient blood collected because of poor blood flow, needle-sickness and other reasons were 0.048 7%(389/799 439), 0.010 6%(85/799 439) and 0.007 1%(57/799 439). Furthermore, the incidence of insufficient blood collected of the three above reasons had statistically significant difference between the years respectively (P<0.05), meanwhile the incidence of insufficient blood collected because of poor blood flow was in a general rising trend significantly (0.036 3%<0.038 2%<0.072 7%, P<0.05). 【Conclusion】 The incidence of insufficient blood collected because of poor blood flow was in the rising trend and further precautions should be considered. Under the normalization of the novel corona-virus pneumonia (COVID-19), the professional knowledge of epidemic prevention and control should be learned and trained, in addition the puncture technique, the ability of offering psychological care and dealing with adverse events during blood collection should be also improved among nurses continually, so as to provide high quality services for blood donors.
