Objective To investigate the effects of a multi-component exercise nursing intervention on frailty，activities of daily living and quality of life in elderly patients with chronic heart failure. Methods Through literature analysis and expert meeting，the multi-component exercise nursing intervention program was formed. A total of 71 elderly patients with chronic heart failure who admitted from January 2022 to September 2022 in a tertiary A hospital in Shandong Province were randomly divided into an intervention group（35 cases） and a control group（36 cases）. The control group received usual care，while the intervention group received an additional multi-component exercise nursing training. 2 groups were evaluated by Tilburg frailty indicator scale，modified Barthel index scale and 12-item short form health survey scale before the intervention，4 weeks and 12 weeks after the intervention. Results A total of 62 patients（31 in the experimental group and 31 in the control group） completed the study. Generalized estimation equation results showed that the inter-group effect，time effect and interaction effect of frailty，activities of daily living and quality of life in the 2 groups were statistically significant（P<0.05）. At 4 weeks and 12 weeks after the intervention，the Tilburg Frailty Indicator scale scores in the intervention group were lower than that in the control group（P<0.05），and the scores of the modified Barthel index scale and 12-item short form health survey scale were significantly higher than those in the control group（P<0.05）. Conclusion The multi-component exercise nursing intervention can effectively improve frailty，activities of daily living and quality of life in elderly patients with chronic heart failure.

Exercise rehabilitation is an important mean to promote early rehabilitation of patients with acute decompensated heart failure（ADHF） during hospitalization. This paper reviews the related research on exercise rehabilitation of patients with ADHF,summarizes the exercise styles,exercise methods,influencing factors and intervention effects,and enriches the intervention content for early rehabilitation of patients with ADHF.

Objective To collect and summarize the best evidence of bathing for premature infants. Methods We systematically searched the British Medical Journal best practice,UpToDate,the Agency for Healthcare Research and Quality（AHRQ）,Registered Nurses’ Association of Ontario（RNAO）,National Institute for Health and Care Excellence（NICE）,Canadian Medical Association（CMA）,Guidelines International Network（GIN）,WHO,American College of Physicians（ACP）,Joanna Briggs Institute（JBI）,Association of Women’s Health,Obstetric and Neonatal Nurses （AWHONN）,Cochrane Library,PubMed,CNKI and Wanfang database to collect the literature including best practice,evidence summaries,guidelines,systematic reviews,expert consensuses,etc. The retrieval period was from January,2011 to April,2021. 2 researchers independently evaluated the quality of the literature,combining with the judgment of professionals,to extract the data from the literature meeting the standards. Results A total of 5 articles were incorporated,including 3 guidelines,1 expert consensus,and 1 evidence summary. The best evidence included 27 pieces of evidence in 6 aspects,including bathing assessment,bathing supplies,bathing timing,bath management,rewarming after bath and vernix protection. Conclusion The research summarized the best evidence of bathing for premature infants. The best evidence should be selected based on the environment,conditions and patient’s willingness,in order to reduce complications and adverse events and to ensure bath safety.
