Objective:To explore the current situation of evidence-based practice competence of nurses with master's degree at Class Ⅲ hospitals in Henan Province and its influencing factors so as to provide a reference for managers to formulate the targeted continuing education plan.Methods:From March 2019 to April 2019, we selected 133 nurses with master's degree of 6 ClassⅢ hospitals in Zhengzhou City of Henan Province as subjects by purposive sampling. All of nurses were investigated with the Chinese version of Evidence Based Practice Evaluation Competence Questionnaire (EBP-COQ) and the Barriers to Research Utilization Scale. Multiple linear regression was used to analyze the influencing factors.Results:Among 133 nurses with master's degree, the total scores of the EBP-COQ and the Barriers to Research Utilization Scale were (98.57±11.01) and (79.66±20.46) respectively. Multiple linear regression analysis showed that the influencing factors of evidence-based practice competence of nurses with master's degree included the working lives, positional titles, attending evidence-based nursing training, awareness to evidence-based practice, accessibility of research funding and resource conditions of evidence-based nursing ( P<0.05) . Conclusions:Nurses with master's degree in Henan Province have the intermediate level of evidence-based practice competence and positive attitudes to evidence-based practice, but their evidence-based knowledge and skills need to be improved. Nursing managers should pay more attention to evidence-based practice competence training of nurses with master's degree, provide many supportive resources and environments, promote evidence-based practice skills training so as to boost the development of specialist nursing practice.

Objective To investigate the symptom clusters of gastric cancer patients before chemotherapy,so as to provide a theoretical basis for the development of targeted management strategies.Methods A total of 228 gastric cancer patients who were treated in the General Surgery Department and Oncology Department of the Second Affiliated Hospital of Zhengzhou University from September 2016 to August 2017 were selected as the survey subjects by convenience sampling method.A cross-sectional survey was used to conduct a questionnaire survey.The Chinese Version Memorial Symptom Assessment Scale(MSAS)was used to evaluate the patients' symptoms before chemotherapy.Correspondence analysis was used to extract symptom clusters.Results A total of 228 questionnaires were distributed,and 224 were effective.The effective recovery rate was 98.2％.Before chemotherapy,the 5 most prevalent symptoms of gastric cancer patients were weight loss(97.8％),dry mouth(95.1％),pain(90.6％),sweating(84.4％)and lack of vitality/fatigue(79.5％).The top 5 symptoms of severity were lack of vitality/fatigue,difficult to focus,body swelling/bloating,swelling of the arms or legs and anxiety.Using the correspondence analysis to get 5 symptom clusters,the 5 symptom clusters were the energy deficiency symptom cluster,digestive tract symptom cluster,physical and mental symptom cluster,surgical related symptom cluster and neurological symptom cluster.The Cronbach's α coefficient was 0.95,0.89,0.92,0.93 and 0.87 respectively.Conclusions This study clarified the pre-chemotherapy symptom clusters of gastric cancer patients,and provided a scientific basis for exploring practical and effective methods of symptom management.At the same time,this research can also provide reference for the applicationof correspondence analysis method in the study of cancer symptom clusters.
