The effective implementation of curricular ideology should be vigorously promoted in the training process of postgraduate students in critical care medicine.The clinical practice of critical care medicine contains a large number of ideological elements.In the process of teaching,teachers need to explore the ideological and political elements closely related to critical care medicine,mainly including:correct value of life,self-supervision spirit,communication and collaboration ability,healer's benevolence,craftsmanship,honesty and integrity in medical practice,as well as the supremacy of the country and the people,and so on.In the process of implementing curriculum ideological and political teaching,teachers are required to continuously improve their professionalism and ethics,improve their teaching methods,and set a good example in their clinical work.In order to better implement the curriculum ideological and political education,it is necessary to establish a perfect teaching system and a unified curriculum ideological and political education material library.

Objective:To evaluate the performance of key performance indicator (KPI) lean teaching management system in clinical medical laboratory.Methods:Combining lean teaching management in universities with KPI system of enterprises, an innovative KPI lean teaching management system was developed and applied in Clinical Medical Laboratory of Guangdong Provincial People′s Hospital (GDPH). A total of 106 teachers, who had worked from January 2021 to December 2022 in GDPH, joined this study. Teachers were divided into 8 professional groups. Firstly, we quantified the teaching workload by class hours, evaluated the teaching outcomes base on national, provincial, school, and college levels to assign different teaching points, and linked the teaching KPI scores to the evaluation, salary, and professional title of teachers. Then, we analyzed the overall teaching points and teaching points for each professional group (2021-2022). Finally, we asked teaching managers, teachers, and colleagues to evaluate the KPI lean teaching management system and compared the effects before and after the implementation of this system.Results:Compared with 2021, the teaching scores of 106 teachers increased significantly from 1.0 (0.2, 2.7) to 3.8 (2.3, 6.0) in 2022 ( Z=8.1, P<0.01). The teaching scores of clinical molecules, clinical coagulation, clinical immunology, clinical microbiology, Huifu laboratory, and clinical biochemistry group were significantly higher in 2022 than the scores they got in 2021 (all P<0.05). Compared with 2021, there were 3 new set up of educational reform projects, 2 submitted teaching articles, 3 new competition awards, 7 outstanding teachers, and 5 outstanding students in 2022. After application of KPI lean teaching management, the evaluation scores of teaching work by teaching managers, teachers, and colleagues are all significantly improved ( P<0.05). Conclusion:KPI lean teaching management system could effectively enhance teachers′ work initiative, improve teaching efficiency and outcome, and promote the teaching quality. Therefore, based on the performance of KPI lean teaching management system in our study, it is possible to realize its potential in terms of lean management in clinical medical laboratory.
