Objective To systematically evaluate the prevalence of sleep disorders and provide evidence for early prevention of sleep disorders in post-ICU patients. Methods PubMed，Embase，Web of Science，the Cochrane Library，CINAHL，CBM，CNKI，WanFang Data and VIP were searched from inception to June 2022. There were 2 researchers who independently screened the literature and assessed the quality of included studies using Critical Appraisal Tools published by Newcastle-Ottawa Quality Scale（NOS）. The meta-analysis was performed by StataSE.12 software. Results A total of 28 studies were included in this study with a total of 3 170 patients. The prevalence of subjective sleep disorders by random effects model was 51.84%[95%CI（45.17%~58.51%）]. The results of subgroup analysis showed that the prevalence of subjective sleep disorders within 1 month，1~3 months，>3~6 months and >6 months after ICU discharge was 50.51%[95%CI（40.97%~60.05%）]、53.34%[95%CI（44.86%~61.82%）]、49.44%[95%CI（32.71%~66.16%）]、29.55%[95%CI（13.28%~45.82%）]，respectively. Meta regression results of single covariate showed that sample size and country were related to heterogeneity（P<0.05）. Conclusion The prevalence of sleep disorders in post-ICU patients is high. Nursing staff should take relevant interventions，strengthen sleep health education and guidance for patients，and reduce the incidence.

Objective The aim of this study was to perform a meta-synthesis of findings of myocardial infarction（MI）patients’ experiences of recovery after returning to society. Methods We searched databases including the Cochrane Library,Joanna Briggs Institute Library,PubMed,Embase,Web of Science,PsycINFO,CINAHL,CBM,WanFang,CNKI and VIP. All of the qualitative research on the real experience of MI patients returning to society after being discharged from the hospital were collected. The search time limit is from the establishment of the databases to November 2021. The JBI critical appraisal tool for qualitative research in Australia was used to evaluate the quality of the included studies,and the results were summarized and integrated by integrating methods. Results A total of 13 original studies were included. 47 findings were collected,and then the similar results were grouped into 11 new categories,and finally these categories were integrated into 3 synthesis results. Integration result 1：living with psychological loads,and the patients were facing physical and mental challenges. Integration result 2：reflecting on the value of life and strive to change one selves. Integration result 3：recognition of the world,and desire for outside help. Conclusion Although MI patients have been treated to save lives,they are still living under different degrees of pressure after discharging from the hospital. The future life is full of uncertainty,and each person’s coping ability is different. Health care workers and members of the public society need to pay more attention to their feelings and needs after returning to society,and to provide necessary health care knowledge and living skills to help them learn to coexist with the disease and better adapt to social lives.

Objective To investigate the impact of a multi-component exercise program based on Wechat applet on improving exercise adherence and the frailty state. Methods 95 pre-frailty of the elderly in a community in Beijing were randomly divided into 2 groups. On the basis of explanation and demonstration，the Wechat applet group used the multi-component exercise course of Wechat applet. The health education group used the way of explanation and demonstration to carry out multi-component exercise health education. The exercise adherence，frailty state and physical function were compared between the 2 groups. All subjects received 3-month intervention. Results 89 participants completed the study. The implementation of the multi-component exercise programs，the improvement of frailty and the improvement of walking speed in the Wechat applet group were better than those in the health education group（P<0.05），but there was no significant difference on grip strength，SPPB and TUGT between 2 groups（P>0.05）. Conclusion The multi-component exercise intervention based on Wechat applet is helpful to enhance the exercise adherence and improve frailty state of the elderly.

Myocarditis is a highly lethal immune adverse reaction associated with immune checkpoint inhibitors （ICIs）,and its diagnosis,treatment and nursing are complicated. This paper summarizes the nursing care of a patient with low-differentiated lung adenocarcinoma complicated with fulminant myocarditis who was treated with ICIs. The key points of nursing care include：monitoring and pre-evaluation of the condition,nursing care supported by ECMO,reducing the risk of infection aggravation,prevention and nursing care of complications,rehabilitation guidance and disease education. After 25 days of active treatment and careful nursing care,the patient’s condition improved and he was discharged smoothly. Telephone follow-up for 6 months showed good condition.

Objective To carry out evidence-based nursing care of standardized oral hydration for prevention of contrast-induced nephropathy（CIN） in patients after emergency percutaneous coronary intervention,and to formulate nursing quality review indicators,and analyze the obstacle factors based on the current situation of clinical practice. Methods Guided by the evidence-based health care model of Joanna Brigga Institute,the problems of evidence-based nursing,team building,systematic retrieval,evaluation and summary of evidence were determined;the nursing indicators and methods were formulated. According to the baseline study results,the obstacle and promotion factors were analyzed,and the corresponding methods and countermeasures were developed. Results A total of 12 pieces of best evidence were included in the study,and 12 quality review indicators were formulated based on the best evidence. The main obstacle factors were the lack of standardized drinking water process,the lack of assessment tools for the risk of CIN,insufficient training of nurses on the knowledge of CIN,and insufficient cognition of patients and their families on contrast nephropathy. The main motivating factors are strong organizational leadership and medical team cooperation and etc. Conclusion Combined with the judgment of clinical professionals,the evidence-based nursing quality review index of oral hydration for prevention of CIN after emergency coronary intervention is scientific,operable and practical,which can lay the foundation for evidence-based nursing.

Objective To collect and summarize the latest relevant evidence of early muscle strength training for stroke patients at home and abroad,so as to provide a reference for the establishment of a scientific program of early muscle strength training after stroke. Methods We systematically searched in UpToDate,Joanna Briggs Institute evidence-based health care center database,National Guideline Clearinghouse,National Institute for Health and Care Excellence,Registered Nurses’ Association of Ontario,American Association of Critical-Care Nurses,National Stroke Foundation of Australia,Cochrane Library,PubMed,Web of Science,Dutch Medical Abstracts database,CNKI,Wanfang database,VIP database and Chinese biomedical literature database for all evidence on early muscle strength training for stroke patients,including guidelines,system reviews,best practice information booklets,evidence summaries,expert consensuses and original research. The retrieval time is from the establishment of the databases to October 30,2019. 2 researchers independently evaluated the quality of literature,and extracted the literature that met the standards with their professional judgment. Results A total of 18 pieces of literature were included,including 5 guidelines,1 evidence summary and 12 systematic reviews. The best evidence includes evaluation,intervention timing,intervention plan,muscle strength training interventions,quality control,effect evaluation and economic benefits. A total of 28 pieces of evidence are summarized. Conclusion We summarized the best evidence of early muscle strength training for stroke patients,and provided evidence-based references for clinical staff to carry out evidence application. It is suggested that the clinical staff should actively carry out the early muscle strength training for stroke patients in combination with the specific situation of the room,the willingness of patients and the evidence of promoting factors,obstacles and coping strategies. At the same time,the evidence should be updated dynamically to ensure the quality.

Objective To retrieve and analyze available evidence on prevention of ventilator-associated pneumonia（VAP） due to methicillin-resistant Staphylococcus aureus（MRSA） and summarize the best available evidence. Methods We searched the PubMed,Embase,Cochrane Library,BMJ-Clinical Evidence,BMJ-Best Practice,uptodate,Joanna Briggs Institute（JBI）,Registered Nurses’ Association of Ontario（RNAO）,National Guideline Clearinghouse（NGC）,National Institute for Health and Care Excellence（NICE）,and complementally searched CNKI,Wanfang Database,VIP Database and CBM published up until June 2018,to collect articles including guidelines,evidence summary（ES）,best practice information sheet（BPIS）,expert consensus,systematic review（SR） and original research. Three authors independently evaluated quality of literatures and extracted data. Results Nine articles were enrolled,including one Chinese language article and eight English articles;one experimental study,one cohort study,five SRs,one expert consensus,and one guideline. Best evidence included：mouth rinses with 15ml of 2% Chlorhexidine（CHX） digluconate for twice per day until discharge,bed bath with Chlorhexidine daily;active screening with nasal and pharyngeal swab culture for MRSA when admitted to ICU and within 24 hours,using mupirocin in the nostrils for MRSA colonized patients,protective isolation might be cancelled for hospitals with high levels of compliance with hand hygiene and standardized infection prevention strategy,cleaning and disinfection of hospital environment and medical equipments. Conclusion Health care providers should take strategies such as active screening for MRSA as patients admitted to ICU,decolonization,mouth rinses with CHX in early mechanical ventilation,and cleaning and disinfection of environment and equipments,to prevent MRSA-VAP.
