Evaluation of Mobile App to Assist in Pediatric Triage (PEWSAPP)

Each ED manages a wide variety of pathologies ranging from a simple general consultation to a life-threatening emergency. Patients require prioritization and triaging as soon as they reach the ED and cannot be seen purely in the order of arrival. 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 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. 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 a pediatric emergency department using the mobile application Caducy® (i-Virtual)

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).

After patient registration, the patient will be installed in the nursing office with one of his parents . After screening a potential life-threatening patient for which treatment would be started first of all, the nurse will collect the signed parental consent for participating to the study. Explanations will be given to the parents regarding the use of the application and the way to calculate the PEWS through a very brief and standardized education. Parents should then proceed to the calculation of PEWS, as far as possible before the intervention of the nurse, using the Caducy® appl with a smartphone dedicated to the study .

After patient registration, the patient will be installed in the nursing office with one of his parents . After screening a potential life-threatening patient for which treatment would be started first of all, the nurse will collect the signed parental consent for participating to the study. the nurse proceed to the calculation of PEWS in blind of parents and to triage process by priorityzing patient in 5 level of gravity (from 1-vital emergency to 5-nonurgent patient). If the medical examination was not proceeded directly after the triage process, nurses were asked to proceed a new triage if the optimal delay of the medical examination was passed.

The Pediatric Early Warning System (PEWS) 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. the PEWS score is calculated by parent using smartphone app and According to the score, patients will be classified as follows: PEWS [0-2] = no risk PEWS[3-4] = moderate risk PEWS [5-9] = High risk

PEWS is calculated again by parent using smartphone app If the medical examination was not proceeded directly after the triage process, nurses were asked to proceed a new triage of the patient if the optimal delay of the medical examination was passed. The delays after which a new triage process should be performed by the nurse are defined according to the triage level given by the nurse using the triage tool as follows: Level 1: < 5 min Level 2: < 20 min Level 3: <60 min Level 4: <120 min Level 5: < 240 min
