Objective By optimizing the in-hospital process of extracorporeal cardiopulmonary resuscitation,the rescue time is shortened and the occurrence of adverse events is reduced. Methods In October 2018,our hospital established a medical failure mode and effect analysis management team. The healthcare failure mode and effect analysis model was applied to analyze the shortcomings of extracorporeal cardiopulmonary resuscitation emergency process,and the emergency process was optimized through literature reviews,expert discussions and consultations,so as to construct standardized extracorporeal cardiopulmonary resuscitation in-hospital emergency process and apply it to the clinic in January 2019. After 2 years of clinical application,we analyzed and compared the risk priority index before and after the optimization process,the time spent in each link and the occurrence of adverse events. Results After the optimization of the emergency process,the risk priority index dropped from（217.63±20.60） points to（102.73±39.95） points;the time spent in each link was shortened;the incidence of various adverse events decreased,and the differences were statistically significant（P<0.05）. Conclusion The application of healthcare failure mode and effect analysis to optimize the in-hospital emergency process of extracorporeal cardiopulmonary resuscitation can effectively improve the delay of first aid and reduce the occurrence of adverse events.

Objective To explore the core competence of ECMO specialist nurses in China and to provide standards for training ECMO specialist nurses. Methods With qualitative research methods,semi-structured interviews were conducted among 10 nurses who managed ECMO independently,3 ICU physicians,2 perfusionists and 3 head nurses. Content analysis was used to summarize and extract the theme. Results 7 themes were extracted,including professional knowledge,clinical practice ability,critical thinking ability,professional development ability,communication and coordination ability,management ability,and personal traits. Conclusion The core competences of ECMO specialist nurses are comprehensive. It is necessary to pay attention to and strengthen these 7 core competences of ECMO specialist nurses,so as to meet the needs of ECMO specialized nursing development.

Objective To translate the Essentials of Magnetism Scale(EOM) into Chinese，and test the reliability and validity of the scale for initially establishing a Chinese version of the Essentials of Magnetism Scale. Methods A total of 1 389 clinical nurses were tested from a tertiary comprehensive hospital in Qingdao using the Chinese version of EOM which was developed through the process of translation，back-translation and cultural adaptation to verify its reliability and validity according to Brislin model. Results The Chinese version scale was extracted for 7 factors and 45 items by the factor analysis using the maximum orthogonal rotation，the cumulative contribution rate was 72.328%. Cronbach’s alpha coefficient for the overall scale was 0.980, the split-half reliability coefficient was 0.919 and the test-retest reliability coefficient was 0.889. Conclusion The Chinese version of the Essentials of Magnetism Scale has been proved to be reliable and valid which can be used to objectively evaluate the magnetic level and health status of nursing work environment in China.
