Objective To investigate the influencing factors of compassion fatigue（CF） among nurses in maternity hospitals,and then to further explore the impact path of factors. Methods 715 nurses in maternity hospitals from Jiangsu were investigated by the cross-sectional survey. A self-developed questionnaire,the Five-Factor Inventory,the Social Support Rate Scale,the Psychological Capital Questionnaire-Revision,and the Compassion Fatigue Scale were adopted to collect data. Results The number of children,personality of neuroticism and agreeableness,social support,and psychological capital are the influencing factors of CF（P<0.05）,while professional titles,length of services,labor relations,personality of extraversion and openness,social support and psychological capital influence compassion satisfaction（CS）（P<0.05）. In structural equation model,the indirect effects of neuroticism on CF or CS existed（ES=0.062,-0.420）. Social support and psychological capital play a partially mediating role in neuroticism and CF（ES=0.017）,accounting for 27.42% of the total indirect effects. They also play a completely mediating role in neuroticism and CS（ES=-0.112）,accounting for 26.67%. Positive personality had a significant indirect effect on CF or CS（ES=-0.158,0.623）,and social support and psychological capital serve as a completely mediating role between them （ES=-0.028,0.102）,accounting for 17.72% or 16.37% of the total indirect effects. Conclusion Nursing managers should take effective measures tailored to personality traits to help nurses meet high levels of social support and psychological capital,so as to promote CS and reduce CF.

Objective To retrieve，evaluate and summarize the best evidence of non-pharmacological interventions for maternal postpartum depression and to provide references for clinical practice. Methods According to the top-down principle of the evidence-based resource 6S model，a systematic search of domestic and foreign databases and websites was conducted on the intervention of postpartum depression，including relevant clinical decision reports，best practices，guidelines，evidence summaries，systematic reviews，and expert consensuses. The search time limit was from the establishment of the databases to March 2022. A supplementary search was performed for randomized controlled trials published between September 2019 and March 2022. There were 2 researchers who evaluated the quality of the literature，extracted and summarized the evidence according to the subject. Results Totally 15 articles were involved，including 1 best practice，3 guidelines，2 expert consensuses and 9 systematic reviews. Finally，28 pieces of best evidence about iatrophysics，psychological interventions，exercise interventions，other interventions，and intervention implementation and monitoring were summarized. Conclusion Non-pharmacological interventions for maternal postpartum depression have various forms and rich contents. Appropriate intervention plans should be made according to the actual situation and the willingness of parturients，and the process of interventions should be well monitored.

Objective To implement evidence-based practice of oral intake management during labor,develop review indicators,analyze obstacles and facilitators during implementation,and formulate reform strategies. Methods With the Joanna Briggs Institute evidence-based health care model as the guiding framework,an evidence-based practice team was formed after the clinical nursing problem was identified to search,evaluate and summarize the evidence,and to develop review indicators as well as review methods. Obstacles and facilitators were analyzed according to the baseline review results,and reform strategies were formulated. Results Totally 18 pieces of best evidence were included and 13 review indicators were formulated. There were 9 indicators with accurate execution rate of <60% and 5 of them were 0. The main obstacles were the lack of attention and relevant knowledge of midwives,the lack of assessment tools for risk factors of restricting oral intake during labor,specific dietary recommendations,management procedures as well as educational materials for different groups. The main facilitators were strong organizational leadership,multi-disciplinary team support,and high maternal and family participation and etc. Accordingly,corresponding reform strategies were formulated. Conclusion The review indicators constructed based on best evidence and combined with professional judgment were scientific,effective,appropriate and feasible. The analysis of obstacles and facilitators and the formulation of reform strategies can provide a guarantee for promoting the clinical practice of oral intake management during labor.
