PRACTICE
Pilot on Remote AutomatiC ulTrasound scan analysIs for hemophiliC patiEnts
Introduction to the pilot
Context
People with hemophilia may experience joint bleeding, which can result in permanent joint damage if not properly treated.
Problem
Presently, the diagnosis of joint bleeding relies on ultrasound imaging, necessitating a physical visit to a specialized center. This limitation poses a hindrance to early detection.
Solution
We are developing a solution that enables patients and caregivers to acquire ultrasound images at home. These images can then be remotely diagnosed by healthcare practitioners.
Overall Objective
To enable the remote diagnosis of joint bleeding, providing a faster and more convenient diagnostic process for patients while reducing costs for the healthcare system.
Objectives
Currently, hemophilic patients need to frequently visit specialized centers, but this is not always possible, for example due to the distance from the center. The project aims to offer a convenient diagnostic procedure that is user-friendly, enabling patients to receive prompt and accurate diagnoses without the necessity of physically attending specialized centers. This approach will help minimize the risks of under or over-treatment, thus providing an added advantage to patients’ overall well-being.
Enhanced monitoring of patients’ joint health status will significantly impact both direct costs, such as medication expenses, and indirect costs, such as follow-up visits. The system is being designed to minimize the burden on healthcare practitioners, allowing them to efficiently and accurately establish diagnosis with speed and reliability.
System components
The patient or caregiver can acquire ultrasound images at home using a portable ultrasound probe connected to a mobile PC. However, acquiring high-quality ultrasound images can be challenging and often requires extensive training. To simplify the process for patients or caregivers, we are developing the GAJA app, which leverages machine learning models to provide guidance during the image acquisition process.
Once the practitioners receive the acquired images, their role is to provide a diagnosis. To expedite the procedure and enhance diagnostic accuracy, we are developing CADET, a specialized computer-aided diagnosis tool. CADET leverages advanced machine learning models to prioritize interventions and intelligently reorganize the received images. Additionally, CADET autonomously identifies conditions like joint distention, providing valuable assistance to practitioners during the diagnostic process.
COD20 is a telemedicine platform. Our goal is to integrate the GAJA and CADET systems with COD20 to facilitate system scalability and provide functions such as visit bookings and diagnosis storage.
