Objective To retrospectively investigate the quality control indexes of clinical blood in Ningbo hospitals from 2019 to 2021.Methods The Questionnaire of Blood Quality Control Indicators for Clinical Use in Ningbo Hospitals was designed by ourselves, and the relevant data of blood use in 88 hospitals were collected, including blood use in hospitals and blood quality control indicators for clinical use, etc. SPSS 22.0 software was used for statistical analysis.Results From 2019 to 2021, the clinical use of red blood cells was 424 928.00 U, frozen plasma 385 804.10 U and platelets 45 200.70 U in Ningbo Hospitals. The qualified rate of clinical blood transfusion application form was 97.79%, the blood type review rate of blood samples was 95.66%, the indoor quality control rate of blood transfusion compatibility test project was 91.05%, the participation rate of interquality assessment project of blood transfusion compatibility test room was 94.08%, the rate of autologous blood transfusion of surgical patients was 48.93%, and the rate of blood transfusion of discharged patients was 4.38%. There were 1.16 professional and technical personnel for blood transfusion per 1 000 units, and 4.74 cases of adverse blood transfusion reactions were reported per 1 000 blood transfusions. The blood use volume of the first and second operating tables was 0.03 U, the blood use volume of the third and fourth operating tables was 0.16 U, the blood use volume of the operating tables was 0.07 U, and the per capita blood use volume of discharged patients was 0.12 U. The per capita blood use volume of patients undergoing transfusion was 2.38 U, and the per time blood use volume patients undergoing transfusion was 1.35 U. The proportions of graduates, undergraduates, junior college and below in the blood transfusion department was 5.80%, 60.78% and 33.42%, respectively(χ²=55.85, P<0.01), and there were statistically  significant differences among different levels of hospitals concerning-academic-qualifications. The proportions of senior title, intermediate title, primary title and below were 19.61%, 39.88% and  40.61%,respectively, and there were statistically significant differences among different levels of hospitals concerning professional titles (χ²=10.69, P<0.01). The proportions of doctors, technicians and nurses were 3.59%, 94.48% and 1.93%, respectively, and there were statistically significant differences among different levels of hospitals concerning specialties (χ²=16.12, P<0.01).Conclusion The average blood use volume per operating table and the average blood use volume of discharged patients in Ningbo are lower than those in the whole country. There are some problems in the blood transfusion department such as the shortage of licensed doctors and transfusion talents. It is necessary to strengthen the construction of talent team and improve the blood quality of clinical use.
