Objective A scoping review was performed to identify the effectiveness，characteristics，and behavior change techniques of intervention strategies for reducing sedentary behavior among older adults. Methods This study was guided by the scope review methodology framework proposed by Arksey and O’Malley. A comprehensive search of databases was conducted in PubMed，Embase，PsycINFO，Cochrane Library，CINAHL，and Sedentary Behavior Research Database to collect the literature on intervention strategies for reducing sedentary behavior among older adults. The search period was from the establishment of the databases to September 20，2022. The study selection and data extraction were performed independently by 2 reviewers. The resulting data were analyzed and arranged using the descriptive analysis and the social network analysis. Results A total of 31 separate studies published between 2011 and 2022 were included in this study. Most intervention strategies were developed based on the Social Cognitive Theory. Almost all sedentary behavior intervention strategies targeted the psychological and behavioral levels of the individual. The main contents of the intervention strategies included goals and plans，feedback and monitoring，natural consequences，social support，repetition and substitution. In the social network analysis，the behavior change techniques that ranked high in degree centrality included goal-setting（behavior），self-monitoring of behavior，action planning，information about health consequences，and feedback on behavior. These intervention strategies could reduce sedentary time from 23 to 151 min/day. Conclusion Domestic nursing researchers should pay attention to sedentary behavior in older adults，and develop intervention strategies for reducing sedentary behavior in local contexts based on the effectiveness，characteristics，and behavior change techniques of the existing sedentary behavior intervention strategies.

Objective To analyze the definition of de-implementation，and provide a theoretical basis for research and clinical practice. Methods Pubmed，ProQuest，CINAHL，CNKI，Wanfang，VIP，and China Biomedical Literature Service System databases were searched. The search time limit was from the establishment of the database to July 2022. As a result，40 articles were selected for analysis. Walker and Avant′s methods were used to perform concept analysis of de-implementation in terms of its definition，pre-factors，post-results. Results De-implementation can be classified into 4 defined attributes：low-value care as the subjects；strategies to apply；4 types of removing，replacing，reducing，restricting；complicated process. The pre-factors can be discussed from the aspects of low-value care，health care systems，patients，ethical and social factors. De-implementation can impact to patients and health care systems. Conclusions The research on de-implementation is still at an early stage. There is a lack of relevant measurement tools for the accurate determination of de-implementation. In the future，research and clinical practice should be carried out based on the concept of de-implementation.

Objective To comprehensively search the relevant research of Ottawa Decision Support Framework （ODSF） and to clarify the specific connotation of its constructs,understand the areas covered by its clinical application,and to analyze its specific role in the research.Methods Using the method of Arksey and O’Malley scoping review,we systematically searched CNKI,SINOMED,Wanfang,VIP,PubMed,Cochrane Library,CINAHL,Embase,Web of science,and screened the literature according to the inclusion and exclusion criteria. 2 researchers independently extracted the key information of the ODSF. Descriptive analysis and topic analysis were used to classify the extraction results.Results A total of 143 documents are included. There are 3 types of conceptual descriptions of ODSF in previous studies,which correspond to the 3 versions of ODSF. The framework covers a wide range of research areas,mainly including cancer,orthopedic diseases,cardiovascular diseases,etc. The guiding role of the framework in the research mainly has 7 categories,and there are obvious differences between domestic and foreign research.Conclusion This study summarizes the connotation and clinical application of ODSF in detail,which can provide guidance for future research.

Objective To analyze the definition of low-value care,and provide a theoretical basis to identify and eliminate low-value care. Methods Pubmed,ProQuest,CINAHL,CNKI,Wanfang,VIP,and China Biomedical Literature Service System databases were searched. As a result,35 articles were selected for analysis. Walker and Avant′s methods were used to perform concept analysis of low-value care in terms of its definition,pre-factors,post-results. Results Low-value care can be classified into 4 categories,including the intervention in which evidence confers no or very little benefit on patients,the intervention that harms outweigh benefits,the intervention without cost-effectiveness,and the care which hardly confirms to the values and preferences of patients. The pre-factors can be discussed from the aspects of knowledge belief,treatment relationship and resource economy. Low-value care adversely affects the physical and psychological conditions of patients,increases the economic burden of health care systems and occupies the time and resources from high-value care. Conclusion The research on low-value care is still at an early stage. There is a lack of relevant measurement tools for the accurate determination of low-value care. Further research on low-value care should be carried out from multi-perspectives in the future.

Objective To explore the research content,theoretical framework,adaptation process,the quality of the methodology and reporting of adaptation of guidelines in the nursing field in China. Methods The literature on the theme of the guidelines adaptation in clinical practice in China was systematically searched from PubMed,Cochrane Library,CINAHL,EMBASE,Scopus,Web of Science,CNKI,Wanfang,VIP database. 2 reviewers independently screened the literature,extracted the data and assessed the quality of the adaptation of guidelines by AGREEⅡ tool and RIGHT statement. Results A total of 23 studies were included. 69.6% of the studies were published in the last 3 years,and only 7 (30.4%) of the studies reported the funding support. In terms of research themes,65.2% of the studies focused on the care of diseases and their symptoms,and only 12 (52.2%) reported the methods used in the process of adaptation,among which 7 (30.4%) used ADAPTE methods. Methodological quality evaluation results showed that the area with an average score of more than 60% out of the 6 areas included scope and purpose,participants,and clarity of expression. The area with the lowest score was editorial independence. According to the quality evaluation results of the report,the areas with an average score of >4 among the 7 areas include basic information,background and recommendation,and the lowest score is funding and conflict of interest declaration and management. Conclusion The number of studies on adaptation of guidelines in the nursing field in China is increasing obviously,but the theoretical framework based on the adaptation of guidelines and the quality of the methodology and reporting of the adaptation guidelines are poor.

Objective To evaluate the evidence-based guidelines for the management of frail elderly at home and abroad,and analyze the characteristics of each guideline,so as to provide references for the management of frail elderly in China. Methods We conducted a systematic retrieval of the relevant guidelines on frailty management of the elderly published or updated since the database was established until October 2018（the deadline for retrieval）,in authoritative domestic and foreign guide websites,Chinese and English databases and the website of the professional society of gerontology and medicine. The 2017 updated version of the clinical research and evaluation tool for quality evaluation of guidelines meeting inclusion and exclusion criteria was used to analyze the characteristics of the guidelines. Results A total of 3 relevant evidence-based guidelines at home and abroad were retrieved. The average standardized scores of quality evaluation for the 6 areas were 97.5% for scope and purpose,68.5% for participants,65.3% for rigor,95.7% for clarity,68.7% for application,and 61.1% for independence. For overall quality,1 was Grade A and 2 were Grade B. Conclusion There is still a lack of evidence-based guidelines for the management of frail elderly at home and abroad,and the quality of developed guidelines needs to be improved,and contents need to be refined. Local evidence-based guidelines in China should be developed to guide the implementation of management of frail elderly.
