UNLABELLED
The Emergency Severity Index (ESI) is a five-level emergency department triage algorithm that provides stratification of patients on the basis of acuity and resource needs, being ESI-1 the highest acuity and ESI-5 the lesser. The ESI triage system was recently adopted at our Emergency Department. We suspect higher acuity patients are facing inappropriate stratification and thus waiting longer to be managed and stabilized.
METHODS
A retrospective review of 100 charts was performed to calculate ESI accuracy by triage nurses and the time waiting to be seen by a physician.
RESULTS
41% of the patients were assigned an ESI level of lesser acuity, while 31.6% received the same score as calculated retrospectively. Retrospective ESI-2 patients that were assigned an ESI-4 upon triage faced inappropriate high median waiting time of 58 minutes.
CONCLUSIONS
The ESI assigned upon arrival correlated with the median waiting time, exposing undertriaged patients to longer waiting times.
未标注
急诊严重程度指数（ESI）是一种五级急诊科分诊算法，它根据病情严重程度和资源需求对患者进行分层，ESI-1表示最高严重程度，ESI-5表示最低严重程度。我们急诊科最近采用了ESI分诊系统。我们怀疑病情较重的患者面临不恰当的分层，因此等待治疗和病情稳定的时间更长。
方法
对100份病历进行回顾性分析，以计算分诊护士判断ESI的准确性以及等待医生诊治的时间。
结果
41%的患者被分诊为较低严重程度级别，而31.6%的患者分诊结果与回顾性计算得分相同。分诊时被判定为ESI-4的回顾性ESI-2患者面临不恰当的较长中位等待时间，为58分钟。
结论
到达时的ESI分级与中位等待时间相关，提示分诊不足的患者等待时间更长。
