ABSTRACT
【Objective】 To investigate the establishment of a competitive performance evaluation management program for blood centers to ensure the blood supply. 【Methods】 A competitive performance evaluation system for Blood Donor Service Department of blood centers in eastern Shenzhen was established. The data concerning blood collection after (May to October 2021, the experiment group) and before (the corresponding period in 2020, the control) the launch of evaluation system was compared, including the proportion of total/novel blood donors in fixed donation sites, the donation rate of 400 mL and pre-collection deferral rate; collected units per shift, the average collection volume of staff, and the growth rate of per capita donation; the proportion of first-time/repeated/double-dose platelet apheresis donors; the proportion of transfer-in/transfer-out of red blood cells; the ratio of group to street blood donors. 【Results】 The proportion of total/novel blood donors in fixed donation sites(81.13% vs 75.87%), the donation rate of 400 mL(58.14% vs 57.91%) and pre-collection deferral rate(76.55% vs 65.92%) in the experimental group was higher than that of the control, while the proportion of pre-collection deferral was lower(18.87% vs 24.13%) (P<0.05). Compared by the control, the units collected per shift, the average collection volume of staff and the blood donation per capita at fixed sites in the experiment group increased by 54.29%, 52.21%, and 3.36% (P<0.05). The proportion of first-time platelet donors was greater than that in the control(43.90% vs 19.61%), while the proportion of repeated platelet donors was lower (56.10% vs 80.39%). The proportion of double-dose platelet donors was lower than that in the control(12.62% vs 22.19%) (P<0.05). The amount of red blood cells transfer-in was 0%, lower than 2.38% in the control group(P<0.05), while the amount of red blood cell transfer-out was 1.86%, higher than 0% in the control group (P<0.05). The proportion of group blood donors decreased from 24% to 15.19%, while street blood donors increased from 76% to 84.81% (P<0.05). 【Conclusion】 Proper competitive performance evaluation system can effectively mobilize employee motivation, improve the efficacy of blood collection and internal management, and ensure clinical blood supply.
ABSTRACT
【Objective】 To explore the development and changes of blood use in various hospitals through statistical analysis of clinical blood use data in Xi′an, so as to provide basis for the decision making of blood banks to formulate and adjust the blood donation recruitment, collection, preparation and supply plan. 【Methods】 The clinical blood supply data of Shaanxi Blood Center from 2015 to 2019 were collected, and statistical analysis was conducted in terms of red blood cells, plasma, platelets, and cryoprecipitate. 【Results】 The blood supply in Xi′an showed an upward trend from 2015 to 2019, and the blood supply in 2019 was the highest in history(737 852 U). Both tertiary hospitals and secondary hospitals had shown an increasing trend in blood consumption, and the average consumption of red blood cells and plasma per person in operation kept decreasing year by year. The consumption of red blood cells in municipal hospitals and private hospitals had increased greatly, and the average consumption of red blood cells per person in operation had shown a downward trend. The amount of platelet use in all kinds of hospitals increased significantly. The proportion of platelet supply in the total annual blood supply kept increasing year by year. The ratio of platelet consumption to red blood cells consumption (hereinafter referred to as platelet-to-red blood cells ratio) in tertiary hospitals was higher than that in secondary hospitals. The platelet-to-red blood cells ratio of all kinds of hospitals had increased year by year. 【Conclusion】 The increase in the number of clinical diagnosis and treatment is the main reason for the increasing demand for clinical blood supply year by year. On this basis, the government and blood banks can predict the clinical blood demand and adjust the plan of blood donation in time. There is still much room for improvement in the annual platelet collection in Xi′an. Hospitals with higher levels of clinical disciplines have relatively high plate-to-blood ratios.The ratio of plasma to red blood cells consumption in tertiary hospitals is abnormal, there might be unreasonable use of blood.
ABSTRACT
【Objective】 To investigate the availability and convenience of emergency blood transfusion in mainland China, and develop strategies for improvement. 【Methods】 The electronic questionnaire was self-made by the research team, and pushed to physicians and technicians related to emergency blood use and supply nationwide through the WeChat group of professional organizations such as the Chinese Medical Doctor Association′s Emergency Resuscitation and Disaster Medicine Professional Committee. The data was automatically aggregated by the internet survey platform named questionnaire star, and analyzed by statistics software SPSS 21.0. 【Results】 1) General information: A total of 3 151 questionnaires were collected, of which 85% (2 678 / 3 151), from 31 provinces, municipalities or autonomous regions in mainland China were valid, and 39%(1 044/2 678), 22%(577/2 678), 39%(1 057/2 678) were from the east, middle and west region, respectively; 78%(2 099/2 678) were from tertiary hospitals, and 22%(579/2 678) secondary hospitals and below; 60%(1 607/2 678), 16%(425/2 678), and 24%(646/2 678) were from Emergency Department(EM), Intensive Care Department (ICU) and other departments respectively. The respondents with senior position titles took up 34%(906/2 678) while those with intermediate and junior position titles took up 30% (798/2 678) and 36%(974/2 678) respectively. 2) Availability : 63%(1 680/2 678) of the respondents experienced untimely and insufficient blood supply at least once during June 2017 to May 2020, of which 75% (1 256/1 680) occurred in the past year. In the past half year, 51% (381/1 057) of respondents in the western region and 34% (713/2 099) in tertiary hospitals experienced more emergency blood shortages (P<0.05). The most prone to clinical blood supply shortage were red blood cells and whole blood, platelets and other plasma components, accounting for 43% (1151/2678), 42% (1125/2678) and 15% (402/2678), respectively. 48% (1 274/2 678) respondents believed that the insufficient blood supply for emergency use " has caused a significant adverse effect on the quality of rescue", and 40% (1 081/2 678) believed that it was " a potential medical safety threat" .3)Convenience: The waiting time for emergency blood transfusionwithin 0.5 h, 1 h and 2 h accounted for 28% (741/2 678), 71%(1 903/2 678) and 90% (2 547/2 678), respectively. The waiting time of emergency blood transfusion within 0.5 h accounted for 50% (286 / 577) in central region, which was significantly higher than that in eastern or western region (P < 0.05). 67% (889/2 678) of respondents experienced blood inventory depletion, of which 30%(792/2 678) had to wait for more than 8 hours for resuming blood supply. 80% (751/1 057) of the respondents in the western region experienced inventory depletion, significantly higher than that in the central region (P<0.05). 4)The influencing factors were mainly insufficient blood donation, growth of clinical demand in blood, blood waste due to expiration and clinical irrational use, accounted for 56% (1 485/2 678), 23% (619/2 678), 7% (183/2 678) and 6% (167/2 678) respectively. 60% (633/1 057) of the respondents in the western region considered insufficient blood donation as the influencing factors, statistically higher than that in the eastern and central regions (P<0.05).5)Suggestions for improvement included more voluntary blood donation, development of blood substitutes, standardization of clinical blood use and extension of blood storage shelf life, accounted for 49% (1 326/2 678), 24% (645/2 678), 19% (499/2 678), and 8% (208/2 678), respectively. 53% (561/1 057) of the respondents in the western region suggested strengthening voluntary blood donation (P<0.05), while 26% (268/1 044), 26% (152/577), 25% (553/2099) of respondents in the eastern, central region and tertiary hospitals respectively suggested strengthening the research and development of blood substitutes (P<0.05). 56% (504/906) of respondents with senior professional titles recommended strengthening voluntary blood donation, while 26% (453/1 772) and 0.9% (164/1 772) of those with intermediate and junior technical titles recommended research and development of blood substitutes and improvement of blood storage technology, respectively(P<0.05). 【Conclusion】 The whole blood reserve can not fully meet clinical emergency needs at present stage, especially in the western region and some tertiary hospitals,, showing the necessity to adopt comprehensive measures to further improve the availability and convenience of emergency blood transfusion, including strengthening voluntary blood donation, developing blood substitutes, prompting rational clinical blood use and improving blood storage technology.
