医疗机构血小板供应现状及影响因素分析OA

Objective To systematically analyze the current status and influencing factors of platelet supply in medical institutions across China,and to explore the problems and future development directions of the existing supply models.Methods From February 25 to March 5,2025,a web-based questionnaire survey was performed.A self-designed ques-tionnaire was distributed to staff in the blood transfusion departments of medical institutions nationwide in China.Data on the current status and influencing factors of platelet supply were collected and analyzed.Results A total of 2 268 responses were collected in this survey,with 1 366 valid questionnaires finally included,covering 33 provinces,autonomous regions,and municipalities directly under the central government across China.The survey revealed that platelet supply in Chinese medical institutions exhibited a pattern of"sufficient in the eastern region,stable in the central region,and scarce in the western region":adequate in East China;generally favorable in South China except Guangxi;centered on Beijing and Tian-jin in North China;basically met but with insufficient reserves in Central China;subject to seasonal fluctuations in Northeast China;only meeting the baseline supply in Yunnan,Guizhou,and Sichuan in Southwest China;and notably short in Qing-hai,Ningxia,and Xinjiang in Northwest China.Family donor mobilization was required in 81.2%(1 109/1 366)of institu-tions,whereas this proportion was only 12.7%(173/1 366)among institutions with sufficient supply.Tertiary hospitals constituted the main users,among which tertiary Class A hospitals had the highest sufficiency rate,and secondary Class B hospitals showed the most pronounced shortage.A total of 84%(1 147/1 366)of institutions lacked a professional manage-ment team;only 19%(266/1 366)had an inventory warning system,of which 88%(234/266)considered it effective.Platelet reservation required 3 days in 33%(458/1 366)of institutions.The mandatory transfusion rate was 30.55%(29/118)when the reservation lead time exceeded 3 days,representing an increase of 5.98%compared with 24.57%(55/180)in the same-day reservation group.For optimization,most institutions called for improved blood donation services,strength-ened education and incentives,establishment of regional coordination and policy collaboration,and supplementary sugges-tions focused on technologies for extending platelet shelf life.Conclusion Regional imbalance in platelet supply across China is prominent,with supply shortages in some provinces,reliance on family donor mobilization in most institutions,weak grassroots support capacity,imperfect management systems,and supply timeliness constraining clinical practice.Sys-tematic improvements are needed in optimizing blood donation services,strengthening regional coordination,improving rele-vant policies,and developing platelet preservation technologies,so as to enhance the level of supply security and patient safety.
