Abstract:
Objective To retrospectively analyze the centralized detection data of 1 unit of leukoreduced suspended red blood cells from blood collection and supply institutions in the Chongqing area from 2021 to 2023, investigate the key processes of blood collection and preparation, and evaluate the quality of regional blood products, so as to provide a basis for establishing unified regional blood quality homogenization.Methods Centralized detection was conducted on leukoreduced suspended red blood cells from six blood collection and supply institutions in Chongqing from 2021 to 2023. The detection data trends were statistically analyzed, and the Kruskal-Wallis H test was used to analyze the quality control items of the six institutions over the three years. The centralized detection results were fed back on-site, and paper survey forms were distributed to understand the quality control situation of each institution.Results The compliance rate of each quality control item of leukoreduced suspended red blood cells from the six institutions was > 85%. The Kruskal-Wallis H test revealed statistically significant differences among the institutions in each item, with H of 44. 86 to 246. 96 and P < 0. 001. Over the three years,the volume and haemoglobin(Hb) results of institutions B and C were more dispersed, while those of institution F were more concentrated. The red blood cell hematocrit(HCT) data of institution B were more dispersed, while those of institutions A, D,and F were more concentrated. The residual leukocyte count data of institution C were more dispersed, while those of institutions A and F were more concentrated. The hemolysis rate at the end of storage fluctuated significantly for institution A.Conclusion Since the implementation of centralized detection, improvements have been made in all links of the blood chain for each institution. However, data analysis still reveals that blood product homogenization needs to be further strengthened.
