Objective To retrieve,evaluate and integrate relevant evidence on the positioning management of preterm infants to provide clinical references. Methods We searched Guidelines International Network（GIN）,National institute for Health and Care Excellence（NICE）,Scottish Intercollegiate Guide Network（SIGN）,National Guideline Clearinghouse（NGC）,Registered Nurses’ Association of Ontario（RNAO）,Joanna Briggs Institute（JBI）,BMJ Best Practice,PubMed,Embase,OVID,Wanfang Database,CNKI,Yimaitong and other websites on all evidence on the positioning management of preterm infants,including guidelines,evidence summaries,best clinical practice manuals,clinical decision-making and systematic reviews,and the search time limit is from the establishment of the databases to August 31,2020. Results Totally 10 articles were involved,including 3 guidelines,5 systematic reviews,1 technical report and 1 clinical decision support. Finally,21 pieces of best evidence about positioning assessment,positioning the preterm infants,positioning equipment and positioning management of exceptional case were summarized. Conclusion This study summarizes the current best evidence on the positioning management of preterm infants and provides an evidence-based basis for standardizing the positioning management of preterm infants. It is recommended that medical staff should consider the clinical situation when applying the evidence,and selectively apply the best evidence to promote health of preterm infants.

The assessment of children’s eating behaviors helps healthcare professionals to identify their poor eating behaviors and develop targeted interventions to prevent problems such as obesity and malnutrition. This article reviews common eating behavior assessment tools for children at home and abroad,and provides a review of the content,characteristics,and applications of the assessment tools,with the aim of providing a reference for the application and development of eating behavior assessment tools for children.

Objective Applying the best evidence of peripheral venous catheter dressing fixation and replacement in clinical practice,to standardize the pediatric nursing care procedure for peripheral venous catheter dressing fixation and replacement,and to improve the specialist nursing care quality of intravenous therapy.Methods Computer decision support system,clinical practice guidelines,systematic reviews and original articles related to intravenous infusion were searched. Through literature quality appraisal,2 guidelines and 1 systematic review were included as references for evidence resources and 12 items of evidence were summarized. After feasibility,suitability and clinical significance evaluation,7 items of best evidence were generated,and finally 4 clinical review indicators were formed. Clinical application of evidence was conducted according to the standard procedures of JBI evidence-based nursing center’s clinical evidence practice application system （JBI-PACES）. Data were collected by questionnaire survey,field observation,interviews and nursing records reviewing. Effects of application were evaluated by nurse’s compliance of standard practice,incidence of phlebitis,incidence of unplanned extubation,and catheter indwelling time.Results Three items with poor compliance such as changing dressing for moisture,looseness and/or significant contamination during baseline assessment were significantly improved after the application of best evidence（P<0.001）. The length of catheter indwelling was significantly prolonged（P<0.001）. There was no significant difference in the incidence of phlebitis（P>0.05）. The incidence of unplanned extubation was significant reduced（P<0.001）.Conclusion Application of best evidence for pediatric peripheral venous catheter dressing fixation and replacement can standardize nursing care procedure,extend the indwelling time,reduce the incidence of unplanned extubation,and improve the quality of specialist nursing care for pediatric intravenous therapy.
