Paediatric early warning systems (PEWS) to reduce in-hospital mortality have been a laudable endeavour. Evaluation of their impact has rarely examined the internal validity of the components of PEWS in achieving desired outcomes. We highlight the assumptions made regarding the mode of action of PEWS and, as PEWS become more commonplace, this paper asks whether we really understand their function, process and outcome.
儿科预警系统（PEWS）旨在降低院内死亡率，这是一项值得称赞的努力。然而，对其影响的评估很少涉及 PEWS 各组成部分在实现预期结果方面的内部有效性。我们强调了对 PEWS 作用模式的假设，并随着 PEWS 的日益普及，本文提出了一个问题，即我们是否真正理解其功能、过程和结果。
