Objective:To explore the driving factors of health promotion behavior in elderly patients with acute myocardial infarction (AMI) who underwent percutaneous coronary intervention (PCI) after discharge, and to provide a basis for improving the health behavior of patients.Methods:This research adopted the method of phenomenological research in qualitative research. From November 2019 to January 2020, purpose sampling was used to select 12 elderly patients with AMI who underwent PCI after follow-up visits in the AMI Outpatient Clinic of a Class Ⅲ Grade A hospital in Guangzhou as the research objects. Semi-structured interview was used to conduct in-depth interviews with patients. The data was analyzed using the Colaizzi 7-step analysis method.Results:A total of two themes were refined: (1) endogenous driving forces, including four sub-themes of positive self-perception of aging, family responsibility perception, expectations for future social development, and health-related sense of control; (2) exogenous driving force, including three sub-themes of social support system, natural and social medical environment, and long-term medical economic costs.Conclusions:The driving forces for health promotion behaviors in elderly patients undergoing AMI after PCI are complex and diverse. Medical and nursing staff should mobilize the endogenous and exogenous driving forces of the patients according to the individual characteristics of elderly patients, urge them to adopt health promotion behaviors and develop a good healthy lifestyle.

Objective:To provide theoretical reference for the construction of effective prevention and control strategies. The study deeply investigates the impact of traumatic birth events on compassion fatigue and inner feelings of midwives.Methods:Fifteen midwives from five tertiary hospitals in Guangzhou were interviewed in depth by semi-structured interview method from April to June 2021. Colaizzi analysis and Nvivo12 plus software were used to analyze and integrate the data and extract themes.Results:Three main themes were extracted, including the characteristics of traumatic birth events (high incidence, sudden and dangerous, preventable and controllable); exacerbating compassion fatigue (reducing compassion satisfaction levels; exacerbating burnout; and aggravating traumatic stress responses); and exploring effective coping strategies (time required for adjustment, seeking stress release).Conclusions:As a strong stressor, traumatic birth events aggravate the symptoms of compassion fatigue in midwives. Managers should pay attention to the occupational exposure of traumatic childbirth events, actively guide midwives to make psychological adjustments. In addition, managers can increase social support and strengthen the ideological and political education of midwives, so that they have good stress tolerance and excellent professional psychological quality.

Objective To provide evidence-based references for the prevention of surgical site infection(SSI)by sum-marizing the best evidence for the prevention of SSI in adult inpatients.Methods The'6S'evidence resource pyramid model was used to systematically search the related evidence in domestic and foreign databases,guideline websites,and academic socie-ty websites from the inception of the database to September 30,2023.Four researchers evaluated the quality of the included guidelines,and two researchers independently evaluated the quality of other types of literature and rated the level of evidence.Results A total of 12 articles were included,including 6 clinical decision making and 6 clinical guidelines.Thirty best items of the evidence were summarized from 7 aspects:diagnosis,clinical symptoms,influencing factors,patient prevention strategies,preventive strategies for medical staff,intraoperative and postoperative treatment,and consultation and education.Conclusion Clinical staff should develop a standardized management plan for infection prevention based on corresponding evidence to reduce the incidence of SSI instead of taking a single measurement.Moreover,they need to formulate a standardized work process for preventing SSI based on the clinical practice and patients'preference.

Refeeding syndrome(RFS)has a high incidence among critically ill patients and significantly impacts the re-covery and prognosis of the patients.In this paper,we reviewed the literature on the risk factors and risk prediction models for RFS,finding the risk factors of RFS included patient-related,treatment-related factors and disease-related factors and the risk prediction models encompassed risk stratification model,risk score models and the Logistic regression models.It was concluded from the review that early assessment was crucial to preventing the occurrence of RFS.However,there was still a lack of reliable RFS risk prediction models with good predictive performance.It was found as well that it was crucial for the prevention of RFS to attach importance to nutritional and serological indicators and other factors.It was expected to be a necessity to conduct prospec-tive and multicenter studies to develop a risk prediction model for predicting RFS for ICU patients.Our review provides a refer-ence for early assessment and intervention for critically ill patients with RFS.

Objective To clarify and analyze the concept and connotation of the reflective practice in nurses.Methods CNKI,Wanfang,CBM,PubMed,Embase,Scopus,CIHNAL database were searched in relation to reflective practice in nurses.The retrieval period was from the inception to Dec.2022.Walker and Avant's concept analysis method was used to analyze the connotation.Results A total of 43 articles were retrieved.6 attributes of reflective practice in nurses were identified,including active engagement,critical thinking,openness and acceptance,making connections with previous knowledge or experiences,extemal support,dynamic and continuity.Antecedents included internal and extemal drivers.The reflective practice in nurses ultimately had a vital impact on themselves,patients and organizations.In recent years Reflective Practice Questionnaire has been one of the most commonly used data collection tools to measure the reflective practice in nurses.Conclusion The concept attributes of reflective practice in nurses were identified by concept analysis method,which provides references for nursing educators to cultivate reflective practice ability of nurses.In future research,researchers can combine the connotations of reflective practice for nurses to develop specific assessment tools for testing the level of reflective practice of nurses and construct the local reflective practice intervention scheme for nurses,so as to promote the development of reflective practice in nursing field in China.

Objective:To evaluate the quality of relevant practice guidelines for the prevention of surgical site infections in adult inpatients and provide a reference for formulating protocols to prevent surgical site infections in adults.Methods:Practice guidelines related to the prevention of surgical site infections in adults published up to June 2, 2020 were retrieved from domestic and foreign databases, guideline websites and the websites of professional societies. The Appraisal of Guidelines for Research and Evaluation Ⅱ (AGREE Ⅱ) was used to evaluate the methodological quality of the included guidelines, and the intra-group correlation coefficient was used to test the consistency between the reviewers.Results:A total of 6 clinical practice guidelines were included, and in terms of the quality, there were 4 grade A guidelines and 2 grade B guidelines. The average standardized scores of AGREE Ⅱ in 6 dimensions were: 87.04% for scope and purpose, 76.62% for stakeholder involvement, 76.56% for rigor of development, 89.58% for clarity of presentations, 81.60% for applicability, and 81.25% for independence.Conclusions:The existing clinical practice guidelines related to the prevention of surgical site infections in adults are relatively comprehensive with a relatively good quality. Nursing staff need to consider the applicability of evidence application, formulate practical infection prevention strategies, and reduce the incidence of surgical site infections in adults.
