The number of visits to emergency departments (ED) has been rising steadily for both adult and pediatric patients over the past decades. resulting in an increase in waiting and care times. Each ED manages a wide variety of pathologies ranging from a simple general consultation to a life-threatening emergency. However, overcrowding in the ED as well as difficulties in monitoring patients waiting for clinical examination, can endanger patient safety. Patients require prioritization and triaging as soon as they reach the ED and cannot be seen purely in the order of arrival. An ideal triage system should be able to identify those who require immediate care (high-level emergency) from those who can wait or those who will not require emergency care (intermediate- to low-level emergency). This triage is mostly carried out by a nurse at the triage zone who must quickly identify high-emergency patients requiring immediate care and organize their care pathway. The triage nurse uses a decision support tool known as a triage tool.~In France, there is no gold standard in pediatric triage and each hospital uses their own home-made triage system. In 2000, the PED of the University Hospital of Nice (France) created a 5-level pediatric triage tool - the pediaTRI - based on clinical items of inspection, interview, and analysis of vital signs. In a pediatric ED (PED) setting, a high-level emergency corresponds to a child presenting an immediate life-threatening risk that could lead to cardio-respiratory arrest or a related emergency, and thus requires rapid intervention. These patients, for whom a Level 1 or 2 is usually assigned by commonly used pediatric triage tools, can also be screened using warning scores that are predictive of clinical deterioration within 24 hours after visiting the PED. Among them, the Pediatric Early Warning System (PEWS) system, created in 2001, is considered to be efficient, easy to use, and reliable. The PEWS system is based on three main components each given a 3-point rating as follows: (a) behavior and early signs of shock, recognizable and assessable by the parents; (b) skin tone and capillary refill time to assess the cardiovascular system; (c) and respiratory rate and oxygen dependence to assess the respiratory system. According to the literature, the optimal cutoff level to calculate the sensitivity and specificity for admission to an ICU, defined as a high-level emergency, is ≥ 4/9. Vitals signs used to calculate the PEWS are usually collected by the nurse at the triage zone. However, new technology such as mobile application may be also used to capture those vital signs (i-Virtual).~Since the parameters of the PEWS system may be evaluate by parents using the application, the investigators want to analyze their ability to assess the level of severity of their children by scoring PEWS in our pediatric emergency department using the mobile application Caducy® (i-Virtual).
