Efficacy and Tolerance of Telerobotic vs Standard Ultrasound Exam in Children

November 2, 2026 updated by: Centre Hospitalier Intercommunal Creteil

Crossover Comparison of the Efficacy and Tolerance of Telerobotic vs Standard Ultrasound Exam in Children

In children with Covid-19, the diagnosis of Kawasaki Disease (KD) and pneumonia should be made very quickly. However, the regional hospitals surrounding Paris don't have the required expertise. The use of MELODY allows the paediatric team to quickly carry out the necessary examinations while avoiding the movement of patients and the risk of contamination.

The MELODY remote system developed by the company AdEchoTech is a CE marking telemedicine technique, allowing an expert to perform an ultrasound scan on a distant patient (several hundred/thousands of kms). The Melody system makes it possible to optimize ultrasound expertise resources wherever they are located (all specialties combined) The feasibility of the clinical use of telerobotic sonography has been demonstrated in adults for abdominal, cardiac and prenatal exam. Thus, the aim of this study is to assess the feasibility of this system in children.

How is the study designed?

Design Details

  • Primary Purpose: Diagnostic
  • Allocation: N/A
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: standard and telerobotic ultrasound

Included patients will have both ultrasound examination: standard ultraosound (abdominal, cardiac or pulmonary depending on the prescription and telerobotic ultrasound

The children will first have a telerobotic ultrasound abdominal, pulmonary or cardiac followed by a classical ultrasound.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Agreement Between Telerobotic and Conventional Ultrasound Examinations Assessed by Cohen Kappa Coefficient
Time Frame: 1 day

Agreement between telerobotic and conventional ultrasound examinations was assessed using the Cohen kappa coefficient based on the overall examination conclusions (normal or abnormal) obtained by the two methods. Kappa values range from 0 to 1, where 0 indicates no agreement beyond chance and 1 indicates perfect agreement; higher values indicate better agreement between the two examination methods.

1 day

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Parent Acceptance of Telerobotic Ultrasound
Time Frame: Up to 4 hours

Parents completed a 5-point Likert questionnaire immediately after the telerobotic ultrasound examination. Responses were reported as the number of participants selecting each response category. Higher levels of agreement indicate greater acceptance.

Up to 4 hours
Patient Site Assistant Satisfaction
Time Frame: Up to 4 hours

Medical assistant satisfaction questioner for the telerobotic examination using a 5-point Liekert scale from 1: "strongly disagree" to 5: "strongly agree"

Up to 4 hours
Sonographer Satisfaction
Time Frame: Up to 4 hours

Sonographer satisfaction questioner for the telerobotic examination using a 5-point Liekert scale from 1: "strongly disagree" to 5: "strongly agree"

Up to 4 hours
Duration of Ultrasound Examination
Time Frame: Within 1 day (during the paired standard and telerobotic ultrasound examinations)

Duration of the ultrasound examination performed using the telerobotic and conventional ultrasound systems.

Within 1 day (during the paired standard and telerobotic ultrasound examinations)
