Objective　To study the optimal management of the closed-loop management in safe practice of nursing teaching in private hospitals. Method　Through analyzing the causes and prob-lems during the teaching of nursing adverse events

the closed-loop management in safe practice of nursing teaching was investigated

including the closed-loop management team

implementation cycle and range

etc. Totally 100 teachers and 220 students were chosen in 27 clinical teaching departments of our hospital during January 2013 and March 2014. The teachers were divided into experimental group (n=50) and the control group （n=50). The closed-loop management model was applied in experi-mental group while routing management was applied in control group. At the same time

220 students' behavior in experimental group was compared before and after the closed-loop management. Through the evaluation of nursing teaching' safe hidden trouble and questionnaire survey

the nursing teaching of both groups were safe. SAS 9.2 was applied to do statistical analysis and non-parametric Wilcoxon Fisher exact test and ?字2 test were used． Results　The number of teachers' operating key points in ex-perimental group was significantly higher than the control group

with statistically significant differ-ences (46 vs. 15) (P=0.000). The safety hazard times of nursing teaching were 38 and 8 respectively before and after the closed loop management

and the difference was statistically significant (P=0.000).In addition，the comparison before the students' implementing the check system

hospital safety index patients and regulation for technical operations and hospital infection was significant after the closed-loop management (P＜0.01 for all). Conclusion　The full implementation of the closed-loop manage-ment

effective tracking and prevention in place

can optimize the safety management of nursing teach-ing.
