Objective To systematically analyze influencing factors of migration stress of patients'families transferred out of intensive care unit(ICU)in China,and provide evidence-based guidance for alleviating migration stress level of families of transferred patients.Methods Computer searches were conducted on China National Knowledge Infrastructure,Wanfang Data Knowledge Service Platform,VIP,China Biomedical Literature Database,Web of Science,PubMed,the Cochrane Library and Embase for observational studies such as cohort studies,case-control studies and cross-sectional studies on factors influencing migration stress among family members of ICU patients.Search deadline was from database establishment to October 2023.Literature screening,quality assessment and data extraction were conducted independently by two researchers in accordance with the inclusion and exclusion criteria.RevMan5.4 software was used to conduct a Meta-analysis of the data results.Results Fifteen studies were finally included,with a total sample size of 2558 and 12 influencing factors were extracted.Fifteen articles were divided into positive scoring group(higher scores,higher levels of migration stress,nine articles)and negative scoring group(higher scores,lower levels of migration stress,six articles)based on instruments used to measure outcome indicators.When analyzing each group,only factors mentioned in the group more than twice were included in Meta analysis.Meta analysis showed that within positive scoring group,family member education level,family member gender,patient awareness,ICU treatment time and family member uncertainty about the disease were factors affecting migration stress of ICU transfer patients'families(P<0.05);In reverse calculation group,educational level of family member,gender of family member,age of patient and ICU treatment time were influencing factors of migration stress of family members of ICU transfer patients(P<0.05).Sensitivity analysis result showed that result of each factor was relatively stable.Conclusion Educational level of family member,gender of family member,age of patient,ICU treatment time,uncertainty of family member's illness are influencing factors of migration stress of family members of patients transferred out of ICU in China.Influence of family member's religious beliefs and patient's consciousness needs further demonstration.

In recent years,with the frequent occurrence of disasters and the rapid development of the urban rescue system,aviation medical rescue can reach the scene of an accident in a short time because of the use of aircraft,with a wide coverage. Helicopters and fixed-wing aircraft can fly over obstacles and directly reach the disaster or accident area,reducing the rescue time;at the same time,because of its Equipped with relatively complete medical equipment,medical personnel can carry out emergency medical treatment on the aircraft,which improves the survival rate of patients;and aviation medical rescue has strong mobility,which can quickly adjust the rescue route and plan according to the specific situation,quickly transmit on-site information,and improve rescue efficiency. Therefore,air medical rescue has become a crucial part of modern medical rescue. In aviation medical rescue,the two most important components are medical staff and medical equipment. Among them,the professional literacy of aviation medical rescue by medical staff often directly determines the quality of aviation medical rescue received by patients. As the largest group of medical personnel,nurses play an important role in aviation medical rescue,expand the popularization of flight nurse training,do a good job in aviation medical rescue reserve,and play an important role in the quality of aviation medical rescue. Through virtual reality (VR) technology,the actual scene of aircraft and aviation medical rescue is simulated by computer,so that nurses can practice through the simulation of equipment and computer,and realistically feel the scenario of aviation medical rescue when a disaster occurs,which also ensures nurses' practical effect. The implementation of this training can not only greatly improve the number of flight nurse training,but also improve the quality of disaster rescue and aviation medical rescue in China. Therefore,the training of virtual reality technology aviation medical rescue nurses is crucial to the training of disaster rescue and aviation medical rescue personnel and the improvement of rescue quality.
