ABSTRACT
Objective:To construct the prognostic prediction model and scoring tool by using severe trauma patients’ physiological indicators on admission, and to verify the clinical application effect and provide a reference for the early evaluation of severe trauma patients.Methods:This study was a retrospective study which adopted cluster sampling. Patients who met the inclusion and exclusion criteria in the emergency department of the First Affiliated Hospital of Soochow University from September 2019 to November 2020 were included. Patients were randomly assigned into the modeling group and the validation group in a ratio of 7:3 based on their outcome in the emergency department. Logistic regression analysis was performed to construct a prediction model, which was simplified as a scoring tool. The model was verified by using validation group and two months’ prospective validation. The efficiency of the simplified scoring tool was compared with that of the revised trauma score (RTS) and the injury severity score (ISS).Results:Totally 863 patients were included in this study, including 604 patients in the modeling group and 259 patients in the validation group. The model included systolic blood, SpO 2 and AVPU score. The AUC for predicting the death of severe trauma patients was 0.938. The AUC of the prediction model was 0.933, the best cut-off point was 5, the sensitivity was 86.7%, the specificity was 94.2%; the AUC of the validation was 0.885, the sensitivity was 83.3%, the specificity was 93.7%; and the AUC of prospective validation was 0.919, the sensitivity was 100%, and the specificity was 76.7%. The AUC of the RTS and ISS were 0.800 and 0.833, respectively. The AUC of RTS was lower than that of the simplified scoring tool constructed in this research. Conclusions:The prediction model and simplified scoring tool are better than RTS in predicting the outcome of emergency severe trauma patients, which are convenient for emergency medical staff to evaluate the severity of trauma patients.
ABSTRACT
Objective To explore the feeling and experience of the nursing undergraduate students in the simulation training for the doctor-nurse cooperation emergency before their internship,in order to provide reference for making excellent teaching and practical plan of emergency nursing.Methods Using phenomenology method,the experience records of thirty-six nursing students were collected.The experience was recorded by Colaizzi method.Results Five themes were summarized by Colaizzi method:preliminary acquaintance of doctor-nurse cooperation; reflection on division of labor cooperation; scan self-ability; focus on interpersonal communication;comprehension of emergency characteristics.Conclusions Simulation training for doctor-nurse cooperation emergency can give nursing students' opportunity of cooperative learning; Simulation training for doctor-nurse cooperation emergency can arouse nursing students' interest of active learning; Simulation training for doctor-nurse cooperation emergency can develop nursing students'habit of reflective learning;Simulation training for doctor-nurse cooperation emergency can improve nursing students' ability of integrative learnng.
ABSTRACT
Objective To analyze the feeling of nursing undergraduates after one semester of earlyclinical placement.Methods School of Nursing at Soochow University initiated Early Clinical PlacementI for the undergraduates recruited from poverty-stricken areas in 2013.Results Each student hadgained a profound understanding of nursing.Conclusions Early clinical placement is helpful for under-graduate to cultivate interest towards nursing and broaden thinking.
ABSTRACT
Objective To develop a deep vein thrombosis health belief questionnaire(DVTHBQ)for patients undergoing major orthopedic operation,and investigate the reliability and validity of the DVTHBQ.Methods The establishment of DVTHBQ was based on the framework of Health Belief Model (HBM) combining theories and experience,and step-by-step through the preliminary experiment,data collection,evaluation of its validity and reliability,etc.Results The items of this questionnaire had a good discriminability.The total internal consistency reliability of the questionnaire was 0.88.The content validity of the questionnaire was 0.95.Factor analysis,which could explain more than 50％ variance,showed that the questionnaire had good construct validity.Conclusions The questionnaire was tested to be of good reliability and validity.The DVTHBQ could be an effective instrument to explain and predict the possibility of taking DVT preventive measures for patients undergoing major orthopedic operation.
