Videoconférence pour la gestion de la dyspnée pédiatrique dans un centre d'appels médicaux d'urgence: le protocole d'étude contrôlé randomisé Visiodys-PED
Dyspnoea is defined as the sensation of difficult or uncomfortable breathing experienced by a patient. It is a significant concern in emergency care, accounting for 8% of calls to the emergency medical call centre (EMCC) and 10% of Emergency department (ED) admissions. Among paediatric patients, dyspnoea accounts from 14-27% of ED admissions, exhibiting notable seasonal variation. Approximately 10% of these patients require hospitalisation, and 1-3% of cases progress to respiratory failure. All these patients require a comprehensive clinical examination to accurately identify signs of severity, ensuring the timely initiation of specialized and effective treatment.
In France, patients are encouraged to contact the local EMCC before visiting an ED. Medical dispatchers assess the clinical condition by phone, based on medical history, symptoms and current treatment. Based on this assessment, the medical dispatcher determines the appropriate decision which may include providing medical advice, directing the patient to an ED, or deploying a mobile intensive care unit (MICU). Seven percent of calls to an EMCC involve paediatric cases, with nearly half concerning children under six years of age with hyperthermia and dyspnoea as most complaints, particularly during epidemic periods. The medical assessment of paediatric dyspnoea by EMCC is particularly challenging. The inability of children to articulate their symptoms, coupled with parents difficulty in describing the situation - often exacerbated by anxiety - creates significant obstacles. Furthermore, the absence of a direct observation by the physician adds to the complexity and could lead to an inappropriate triage and management.
Telemedicine uses communication technologies for remote consultations, electronic record management, and document sharing. It enables real-time visual evaluation, thereby improving diagnostic accuracy and decision-making. While evidence supports its benefits in managing adult dyspnoeic patients, further research is essential to validate its efficacy in paediatric settings, particularly within EMCC.
This study will aim to evaluate the effectiveness of telemedicine within an EMCC and utilising real-time visualization in reducing inappropriate triage of children requiring care for acute dyspnoea.

Intervention / Traitement |
|---|---|
|
Aucune intervention: Standard medical dispatching process (Control group)
The emergency physician dispatcher conducts a standard medical dispatching process. |
|
|
Expérimental: Addition of telemedicine to standard medical dispatching process (Experimental Group)
The emergency physician dispatcher conducts a standard medical dispatching process with the addition of telemedicine using video calls. |
In the experimental group, the same approach is used, with the addition of telemedicine using video calls. Callers are invited to use their smartphone camera to enable real-time video assessment. The medical dispatcher sends a secure link (via a platform provided by Enovacom, Nomadeec, Bordeaux, France) to the caller's smartphone, allowing video streaming through a secure internet connection. Once the link is validated by the caller, the live video feed from the smartphone camera is transmitted directly to the dispatcher's computer screen, providing a visual evaluation to support clinical decision-making. |

Proportion of patients inaccurately managed

The primary endpoint is the proportion of patients inaccurately managed (over-triage or under-triage) Over-triage is defined as a situation where a patient is:
Under-triage is defined as a situation where a patient is kept at home with medical advice or directed to a family practitioner after the primary call AND later dispatched to hospital by a family practitioner or after a second call to an EMCC for dyspnoea, or hospitalised or dead within 24h following the primary call. |
