时间控制模式在血液分离机运行管理中的价值研究

Research on the value of time control mode in the operation management of blood separator

目的:构建血流分离机时间控制管理模型,探讨其在血液分离机运行管理中的应用价值。方法:分析成分血采集血液分离时间延迟原因,采用数据挖掘算法分析其影响因素与时间控制水平的关联性,在时间评估预测等多维度构建血液分离时间控制管理模型,制定时间控制管理对策。选取2019-2022年上海市徐汇区中心医院的600名献血者和采血期间临床在用的17台血液分离机,根据管理模式不同,将其分为对照组(300名献血者,14台血液分离机)和观察组(300名献血者,15台血液分离机,含对照组12台和新增加的3台),对照组血液分离机采用质量控制模式,观察组采用时间控制模式,对比两组成分血采集过程中的问题数、延迟比例、满意人数和参与采集成分血工作的相关医务人员考核成绩。结果:观察组成分血采集过程中发生设备、医用耗材、医务人员及献血者相关问题的献血者人数分别为11名(占3.7%)、17名(占5.7%)、7名(占2.3%)和18名(占6.0%),均少于对照组,其差异有统计学意义(x^(2)=7.192、6.822、8.153、11.405,P<0.05);观察组成分血采集过程中血液分离机运行正常、明显延迟和显著延迟的献血者人数分别为236名(占78.7%)、46名(占15.3%)和18名(占6.0%),运行正常人数占比高于对照组,明显延迟和显著延迟占比低于对照组,其差异有统计学意义(x^(2)=17.821、7.131、8.549,P<0.05);观察组献血者满意人数为284名(占94.7%),高于对照组,其差异有统计学意义(x^(2)=30.171,P<0.05);参与观察组献血者成分血采集工作的医务人员考核成绩为(91.14±4.86)分,高于对照组,其差异有统计学意义(t=4.587,P<0.05)。结论:时间控制模式能够控制血液分离机运行问题发生概率,缩短血液分离机运行延迟时间,改善献血者献血体验和采血服务质量,提高医务人员业务水平。

Objective:To establish a time control mode for component blood collection and to discuss its application value in the operation management of blood separator.Methods:The causes for delay in blood separation time in blood component collection were analyzed,the correlation between influencing factors and time control level was analyzed by using data mining algorithm,and time control management countermeasures were developed by running time prediction.A total of 600 blood donors and 17 blood separators in clinical use in Shanghai Xuhui District Central Hospital from 2019 to 2022 were selected and divided into a control group(300 blood donors,14 blood separators)and an observation group(300 blood donors,15 blood separators,including 12 of control groups and 3 newly added)according to different management modes.The control group adopted the quality control mode,the observation group adopted the time control mode.The number of problems,the proportion of delay,the number of satisfied people and the assessment results of relevant medical staff in the blood component collection process were compared between the two groups.Results:The number of blood donors with problems related to equipment,medical consumables,medical staff and blood donors during the blood component collection process in the observation group was 11(accounting for 3.7%),17(accounting for 5.7%),7(accounting for 2.3%)and 18(accounting for 6.0%),respectively,which were lower than those in the control group,the difference was statistically significant(x^(2)=7.192,6.822,8.153,11.405,P<0.05).The number of blood donors whose blood separators were in normal operation,apparent delay and significant delay in the observation group were 236(accounting for 78.7%),46(accounting for 15.3%)and 18(accounting for 6.0%),respectively,and the proportions of normal operation were higher than those in the control group,the proportions of apparent delay and significant delay were lower than those in the control group,the difference was statistically significant(x^(2)=17.821,7.131,8.549,P<0.05).The proportion of blood donors satisfied was 284(accounting for 94.7%)in the observation group,which was higher than that in the control group,the difference was statistically significant(x^(2)=30.171,P<0.05).The assessment score of medical staff involved in blood donors in the observation group was(91.14±4.86),which was higher than that in the control group,the difference was statistically significant(t=4.587,P<0.05).Conclusion:Time control mode can control the probability of the problems in the operation of blood separator,shorten the delay time of blood separator operation,improve blood donation experience of blood donors and blood collection service quality,and improve the professional level of medical staff.
