In the Paediatric emergency department scenario there were considerable efforts developing indicators over the past decade, specially referring to process, e.g. timeliness. Nevertheless, to fully characterize quality in Paediatric emergency department, indicators are developed but require further assessment and a more complete validation. This paper's aim is to emphasise the importance of data quality, data cleaning and the indicator choice in indicator production. The dataset provided for this analysis is from the São João Hospital Centre's information system and is composed by records of all the visits to the paediatrics emergency department from the 1st of January of 2014 to the 31st of December 2016. Only the variables time from admission to triage, admission to physician and length of stay were selected from the dataset to be analysed. Summary statistics and plots of each variable through the hours of the day were produced. Considering waiting time from admission till being seen by a physician, the variability of the arithmetic mean and median through the hours of the day range from 18 to 73 and 14 to 49 minutes of waiting time respectively. The maximum difference between indicators at a specific time happens at 0 a.m. and is 24 minutes. When considering waiting time from admission to triage the arithmetic mean is 15.2 however 75% of the children i.e. 3rd quartile waited 12 minutes or less. The choice of indicator is essential, it should accurately reflect what is being measured, taking into account the action that might be taken with the information.
在儿科急诊科的情况下，过去十年为制定指标付出了巨大努力，特别是在流程方面，例如及时性。然而，为了全面描述儿科急诊科的质量，指标已经制定出来，但还需要进一步评估和更全面的验证。本文的目的是强调数据质量、数据清理以及指标生产中指标选择的重要性。本次分析所提供的数据集来自圣若昂医院中心的信息系统，由2014年1月1日至2016年12月31日期间儿科急诊科所有就诊记录组成。仅从数据集中选取了从入院到分诊的时间、入院到见医生的时间以及住院时间这几个变量进行分析。针对每个变量，通过一天中的各个小时生成了汇总统计数据和图表。考虑从入院到被医生诊治的等待时间，一天中各小时的算术平均值和中位数的变化范围分别为18至73分钟和14至49分钟的等待时间。特定时间指标之间的最大差异出现在凌晨0点，为24分钟。当考虑从入院到分诊的等待时间时，算术平均值为15.2分钟，然而75%的儿童（即第三四分位数）等待时间为12分钟或更短。指标的选择至关重要，它应准确反映所测量的内容，同时要考虑到利用这些信息可能采取的行动。
