Objective To explore the expert consensus on risk assessment and preventive nursing of venous thromboembolism（VTE） in general surgical patients. Methods This consensus was drafted through a systemic literature review on VTE prevention and the interviews of nursing experts. The draft was thereafter reviewed by a total of experts in related fields,and it was finalized after 2 rounds of expert consultation. Results 4 domains with 26 components were established through a modified Delphi method. The effective recovery of the ques-tionnaire was 100%;the expert judgment coefficient was 0.960;the familiarity was 0.912;the authority coefficient was 0.936. The Kendall coefficients of the first and second level topics in the 2 rounds were 0.149 and 0.261,and 0.122 and 0.203,respectively,with statistically significant differences（P<0.05）. The consensus includes risk factors for VTE in general surgical patients,risk assessment,risk response,education and quality control,and it is applicable to perioperative patients of general surgery. Conclusion The consensus was based on the recommendations of 25 clinical nursing experts. The results are scientific,rigorous and authoritative,and can provide guidance for clinical nursing staff in the prevention and control of VTE in general surgical patients.

This paper reviews the existing assessment tools，outlines the development process，main contents，and application status of universal and disease-specific health-related quality of life assessment tools for patients with DVT，analyzes the characteristics and limitations of existing tools，and aims to provide references for clinical selection of appropriate assessment tools and for the development of health-related quality of life assessment tools for patients with DVT in accordance with the cultural background of China.

Objective To comprehensively retrieve and analyze evidence related to deep vein thrombosis（DVT）prevention after joint replacement and to summarize the best evidence. Methods We systematically searched for evidence on DVT prevention after joint replacement in BMJ Best Practice,UpToDate,JBI,YiMaiTong,GIN,NGC,NZGG,NICE,SIGN,NHMRC,CPG Infobase,CINAHL,EMBASE,PubMed,WOS,Wanfang and CNKI databases to collect relevant clinical decisions,evidence summaries,clinical guidelines and expert consensuses. The timeframe of data search ran from January 2015 to November 2020. 2 researchers independently evaluated the quality of the articles,and classified the evidence according to the Joanna Briggs Institute evidence-based pre-grading system（2014 edition）. Results A total of 13 articles were included,including 3 clinical decisions,2 evidence summaries,4 guidelines and 4 expert consensuses. Combined with professional judgment,16 pieces of best evidence in 6 aspects were summarized,including risk assessment,health education,preventive measures of nursing care,mechanical prophylaxis,pharmacological prophylaxis,and promotion of clinical implementation of preventive measures. Conclusion The best evidence summarized on the prevention of DVT in patients after joint replacement can provide evidence for clinical nursing work.

Objective To understand the work content of deep vein thrombosis （DVT） preventive care after hip and knee replacement,and to clarify the gap between the current practice and the best evidence. Methods From June to October 2019,we used the field research methods to conduct a 5-month participatory observation about the nursing work in the joint surgery ward in a level A tertiary hospital in Beijing. We used the three-level coding method of qualitative research to conduct field notes analysis. Results Through the care experience of participating in 391 cases of preventing DVT after hip and knee replacement,this study clarified the work content of preventive care,and extracted 4 work content themes,namely Education,Enforcement,Evaluation and E-recording,which fit with the best evidence. However,there is a partial gap between the implementation effect and the best evidence,and it still needs further development in enhancing health education and early activities promotion. Conclusion Through the field research,we have learned about the nursing work content in preventing DVT after hip and knee replacement,and the gap between the present situation and the best evidence and the possible reasons. Carrying out evidence-based nursing research and constructing scientific,normative and clinically feasible standardized preventive nursing plans are the best ways to prevent DVT after hip and knee replacement.

Objective To analyze the situation and hot trend of venous thromboembolism（VTE） prevention abroad,in order to provide references for clinical guidelines and scientific research for nursing staff in China. Methods Core journal articles related to venous thromboembolism and prevention from Web of Science（WOS） from 2005 to 2020 were retrieved. CiteSpace software was used for the bibliometric and cluster analysis. Results The volume of papers issued in the research of VTE prevention is on the whole increasing trend. The research mainly focuses on drug prevention,physical prevention,complications observation,risk identification and VTE prevention in patients with different diseases. Among them,“precautionary duration” “intermittent pneumatic compression devices” “stroke”“anticoagulation” “clinical practice guidelines” and “oral anticoagulants” are the hot spots in the current research frontier. Conclusion The prevention of VTE is attracting the attention of scholars. It is recommended to promote the development of VTE prevention research in China and continuously improve the quality of clinical care by specifying the focus of VTE prevention research,broadening the range of VTE prevention populations,and formulating VTE preventive care guidelines.

Objective To establish an expert consensus on nursing prevention and control of venous thromboembolism（VTE） in adult patients with coronavirus disease 2019（COVID-19）. Methods This consensus was drafted through a systemic literature review on COVID-19 diagnosis and management plan,VTE prevention and control,and interviewing nursing experts from front-line epidemic control. The draft was thereafter reviewed by a total of 18 experts in related fields. This consensus was finalized after 2 rounds of discussions and modifications. Results The expert consensus covers the following 5 topics,namely VTE risk factors,VTE risk assessment,VTE nursing prevention and control,VTE prewarning and monitoring,and health care education of VTE prevention and control after discharge. Conclusion The consensus was drafted and finalized on a scientific and practical basis,which can provide guidance for clinical nurses in prevention and control of VTE in adult patients with COVID-19.
