Objective  To explore the application effect of in situ scenario simulation(ISS) method in advanced cardiac life support (ACLS) training for eight-year clinical medicine students.

  Methods  Eight-year clinical medicine students who underwent clinical internship in Peking Union Medical College Hospital from September 2021 to September 2022 were randomly divided into ISS group and traditional training group. After the training, assessment on the theoretical knowledge and practical operation was conducted. The training effect of the ISS group was evaluated by comparing and analyzing the results of theoretical knowledge and operation skill of ACLS.

  Results  A total of 89 trainees participated in ACLS training and completed the assessment, including 44 in the ISS group and 45 in the traditional training group, with no statistically significant difference in gender between the two groups (P=0.462). The theoretical and operation skill test scores of ISS group were better than those of the traditional training group (80.36±6.46) vs.(65.33±10.43), (67.84±11.27)vs.(46.33±18.75), both with significant statistical differences (both P=0.000). According to the students of the ISS group, through ISS training, the identification of critically ill patients, the mastery of ACLS process, and the awareness of teamwork significantly improved.

  Conclusion  The teaching method of ISS can effectively improve the skill operation ability of ACLS and crisis response, and enhance the quality of recovery to some extent.
