ICU物联网智慧血液管理方案的构建及应用

Construction and application of the Internet of Things intelligent blood management scheme in ICU

目的探讨与评价ICU物联网智慧血液管理方案的应用效果。方法基于无线射频识别技术(radio frequency identification,RFID)开发智能血液冰箱及物联网血液转运箱,以及自动化智能血液(库)管理系统与闭环式输血信息管理系统,构建ICU物联网智慧血液管理方案,对重症患者输血管理实施全流程信息化监管和追溯管理,并进行动态调控与评价。将ICU物联网智慧血液管理方案应用前(2021年5月-10月)与应用后(2021年11月-2022年4月)的用血管理数据进行比较,评价该方案在ICU用血管理中的作用。结果ICU物联网智慧血液管理方案应用前180例患者累计用血2170例次,应用后158例重症患者累计用血3611例次;血袋暴露于非冷链时间由应用前8(5.5,15)min下降至应用后0.5(0.5,1)min,每份血制品平均配送时长由应用前的8(5.5,15)min下降至应用后的1(0.5,1)min,ICU预防备血率由应用前的12.0%(260/2170)上升至应用后的59.0%(2130/3611),病历检查对比情况合格率由应用前的68.3%上升至应用后的89.9%,差异均具有统计学意义(P<0.001)。结论ICU物联网智慧血液管理方案有助于实现ICU血制品的精准监管,提高ICU用血效率,确保ICU用血安全。

Objective To explore and evaluate the application effectiveness of Internet of Things(IoT)blood man-agement scheme.Methods Based on radio frequency identification technology(RFID),we developed intelligent blood refrigerators and IoT blood transfer boxes,automated intelligent blood(bank)management systems and closed-loop blood transfusion information management systems,an intelligent management system for ICU blood use was constructed to implement full-process informatization supervision and traceability management,and conduct dynamic regulation and evaluation for blood transfusion management of critically ill patients.We selected and compared the blood management data of critically ill patients before the application of intelligent blood management system(May 2021 to October 2021)and after the allocation(November 2021 to April 2022),and evaluated the role of this sys-tem in blood management in ICU.Results Before the application of IoT intelligent blood management scheme,a total of 2170 cases of blood use were used in 180 critically ill patients,and 3611 cases of blood use were used in 158 critically ill patients after the application.The non-cold chain time of blood bag decreased significantly from 8(5.5,15)min before implementation to 0.5(0.5,1)min after implementation.The average delivery time of each bag of blood decreased from 8(5.5,15)min before implementation to 1(0.5,1)min after implementation.The ICU pre-ventive blood preparation rate increased from 12.0%(260/2170)before the implementation to 59.0%(2130/3611).The qualified rate of medical record examination increased from 68.3%to 89.9%.The differences were statistically significant(P<0.001).Conclusion The IoT intelligent blood transfusion scheme was helpful for the precise blood management for critically ill patients,improving the efficiency of blood use,and ensuring the ICU blood safety.
