Objective To form an expert consensus on the implementation and removal of psychiatric protective restraints,and to standardize the related contents of the implementation and removal of psychiatric protective restraints. Methods According to the level of evidence,the evidence-based method was used to retrieve,evaluate and summarize the evidence in the field. The recommendations and research conclusions for the implementation and removal of the psychiatric medical protective restraints were extracted,and the rough consensus was formed. Through 2 rounds of enquiry and 2 experts discussion meetings,the final version of the consensus was formed by combining with the expert opinions,adjusting,modifying and perfecting the first draft. Results The positive coefficients of experts in the 2 rounds of correspondence consultation were 100%;the degree of authority of experts was 0.90;the mean value of importance of each index was>3.5,and the coefficient of variation was less than 0.25,and the expert Kendall harmony coefficient was 0.146 and 0.166,respectively （all P<0.01）. Finally,a consensus was reached on the recommendation of 10 parts,including the application group of psychiatric restraints,premise and principle,objective,key points of assessment,basic requirements,record sheet,flow chart,intervention strategies in the implementation process,ethical issues and risks,and suggestions. Conclusion The consensus provides guidance for the practice of psychiatric protective restraints and makes psychiatric restraints more standardized.

Objective To construct a scientific and systematic core competence evaluation index system for nurses participating in ECMO technology,in order to provide references for the training,assessment and competence evaluation of nurses. Methods Through literature review and semi-structured interviews,the preliminary draft of the core competence evaluation index system for nurses participating in ECMO technology was formed in this study. From February to April 2021,25 experts from 6 provinces in China were consulted by Delphi method,and the weight of indexes at all levels was determined by analytic hierarchy process. Results The effective recovery rates of the 2 rounds of expert consultations were 90.00% and 92.59%,respectively;the expert authority coefficient was 0.886,and the Kendall harmony coefficient was 0.205（P<0.001） in the second round. The final core competence evaluation index system for nurses participating in ECMO technology includes 7 first-level indexes,19 second-level indexes and 70 third-level indexes. The first-level indexes include professional knowledge,clinical practice ability,critical thinking ability,professional development ability,communication and coordination ability,management ability,and personal traits. Conclusion The core competence evaluation index system for nurses participating in ECMO technology in this study was scientific and reliable,which can provide valuable references for the training,assessment and competence evaluation of nurses.

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 build a scientific and systematic evaluation index system of hospital-community continuous nursing quality after percutaneous coronary intervention（PCI） to provide a reference for nursing managers and clinical nurses to objectively evaluate the quality of hospital-community continuous nursing after PCI. Methods This study was conducted from November 2019 to April 2020 based on the three-dimensional quality structure model of“structure-process-result”,using literature review,semi-structured interviews,expert consultations and analytic hierarchy process to determine the content of the hospital-community linkage continuous nursing quality after PCI evaluation index system and the weight of each index. Results The effective recovery rates of the 2 rounds of expert consultations were 95% and 100% respectively;the expert authority coefficients were 0.933 and 0.937 res-pectively;the Kendall harmony coefficients were 0.201 and 0.226 respectively（P<0.001）. The final evaluation index system includes 3 first-level indicators,14 second-level indicators and 62 third-level indicators,among which the structural quality includes 4 second-level indicators and 16 third-level indicators;the process quality includes 3 second-level indicators and 18 third-level indicators;the result quality includes 7 second-level indicators and 28 third-level indicators. Conclusion The hospital-community continuous nursing quality evaluation index system constructed after PCI is scientific and reliable,which can provide a basis for continuous nursing quality evaluation and continuous improvement.
