摘要Background:Pediatric emergency rooms (PERs) in Chinese hospitals are perpetually full of sick and injured children because of the lack of sufficiently developed community hospitals and low access to family physicians.The aim of this study was to evaluate the clinical value of a new five-level Chinese pediatric emergency triage system (CPETS),modeled after the Canadian Triage System and Acuity Scale.Methods:In this study,we compared CPETS outcomes in our PER relative to those of the prior two-level system.Patients who visited our PER before (January 2013-June 2013) and after (January 2014-June 2014) the CPETS was implemented served as the control and experimental group,respectively.Patient flow,triage rates,triage accuracy,wait times (overall and for severe patients),and patient/family satisfaction were compared between the two groups.Results:Relative to the performance of the former system experienced by the control group,the CPETS experienced by the experimental group was associated with a reduced patient flow through the PER (Cox-Stuart test,t =0,P ＜ 0.05),a higher triage rate (93.40％ vs.90.75％;x2 =801.546,P ＜ 0.001),better triage accuracy (96.32％ vs.85.09％;x2 =710.904,P ＜ 0.001),shorter overall wait times (37.30 ± 13.80 min vs.41.60 ± 15.40 min;t =11.27,P ＜ 0.001),markedly shorter wait times for severe patients (2.07 [0.65,4.11] min vs.3.23 [1.90,4.36] min;z =-2.057,P =0.040),and higher family satisfaction rates (94.23％ vs.92.21％;x2 =321.528,P ＜ 0.001).Conclusions:Implementing the CPETS improved nurses' abilities to triage severe patients and,thus,to deliver the urgent treatments more quickly.The system shunted nonurgent patients to outpatient care effectively,resulting in improved efficiency of PER health-care delivery.
