Knowledge for unintentional injury and risky behavior among the school-age children in Changsha city of China / 中南大学学报(医学版)

OBJECTIVE@#To investigate the current status on knowledge for unintentional injury and risky behavior among school-age children in Changsha, China, and to provide scientific evidence for the preventive strategies.
@*METHODS@#A cross-sectional study was conducted on 866 students who were between 6 and 12 years old in Changsha. Two primary schools were selected by stratified cluster random sampling from all primary schools of Changsha city to collect the information regarding knowledge for unintentional injury and risky behavior occurring in the 6-month period before the survey.
@*RESULTS@#The mean score for knowledge of unintentional injury was 11.83±2.38. The levels of knowledge for unintentional injury differed significantly in child's age, parents' education background and child's injury history (P0.05).
@*CONCLUSION@#It is a common phenomenon in school-age children who are lack of the knowledge for unintentional injury and risky behavior. This study provides useful information on the risk factors for unintentional injury and risky behavior, which would be significant for prevention program.

Value of triage early warning score for trauma patients in an emergency department / 中南大学学报(医学版)

OBJECTIVE@#To evaluate the predictive accuracy of the triage early warning score (TEWS) in the prognosis and emergency treatment for trauma patients admitted to the emergency department (ED).@*METHODS@#A total of 456 trauma patients (>12 years old) admitted to ED at an education and research hospital in approximately 4 months were prospectively studied. Th e TEWS was recorded in all patients. Th e primary end-point was during 28 days and the emergency responses (such as cardiopulmonary resuscitation/electrical defibrillation, mechanical ventilation) in the ED.@*RESULTS@#Patients with TEWS less than or equal to 9, from 10 to 13, or greater or equal to 14 had mortality rates of 0.98%, 52.63%, or 80%, respectively. An increase in 1 point within the range of 17-point TEWS would be associated with an odds ratio (OR) of 2.14 for death [95% confidence interval (CI): 1.759 to 2.604]. In predicting mortality rates during 28 days, the cut-point was greater than 8, the sensitivity was 87.10% (95% CI: 70.2% to 96.4%), the specificity was 92.47% (95% CI: 89.5% to 94.8%), and the areas under the receiver operating characteristic curves (AUCROC) was 0.929 (95% CI: 0.902 to 0.951). Th e AUCROC of TEWS in predicting the emergency responses for CPR/electrical defibrillation application or mechanical ventilation was 0.969 (95% CI: 0.949 to 0.983) or 0.897 (95% CI: 0.865 to 0.923), respectively.@*CONCLUSION@#TEWS is effective in predicting the prognosis and emergency treatment for trauma patients admitted to ED.
