Clinical Trial Summary

Deepcath is the first step to the introduction of artificial intelligence in catheter care. A better use of visualisation of catheter exit site should be used not only by the HCWs but also by the patients and their family.

A deep learning system able to detect visual abnormalities of the catheter exit site will be an helpful tools to develop a continuous follow-up of intravascular catheters.

Recruitment information / eligibility

• Enrollment: 1000
• Est. completion date: December 31, 2023
• Est. primary completion date: December 31, 2023

• Gender: All
• Age group: 18 Years and older

Eligibility

Inclusion Criteria:

Patients over 18 years of age Patients with one or more implanted central venous, midline, piCCline, arterial, or peripheral catheters.

Patient and/or trusted person and/or family who have verbally stated their non-objection to the study Patient affiliated or beneficiary of a social security plan

Exclusion Criteria:

Patients presenting a peripheral identification sign close to the catheter insertion point cannot be masked when the photograph is taken. Thus, jewelry, clothing, tattoos, scars, and birthmarks are identifying features.

Patients whose catheter insertion point is not visible.

• Infections

Intervention

Diagnostic Test:
• Photographs collection phase
Three medical experts have been selected to review the photo collected. Each expert medical assesses the presence of local signs of infection on the photographs by annotating them directly via a dedicated software. They will annotate local signs: redness, perfusion extravasation, necrosis, hematoma, edema, non-purulent discharge, and purulent discharge. A convolutional neural network model will determine the probability of local sign presence. Each picture will be annotated to determine the main characteristics of the catheter. A dataset preparation with photo cropping will be performed for modelling.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The number of correct predictions for redness divided by the total number of predictions	Overall classification accuracy of the learning model compared to the assessment of three independent medical experts on the detection of the presence of redness greater than or equal to 5 mm at the catheter insertion site.	through study completion, an average of 1 year
Secondary	The ratio of true positives and total positives predicted:	The precision metric focuses on Type-I errors(FP). A Type-I error occurs when we reject a true null Hypothesis.	through study completion, an average of 1 year
Secondary	The number of correct predictions for indurated venous cord divided by the total number of predictions	Evaluate, on the basis of images of peripheral catheter insertion sites, the reliability of the learning model on the assessment of the presence of indurated venous cord.	through study completion, an average of 1 year
Secondary	The link between presence of local signs and infection	Measure the correlation between the appearance of the catheter puncture site and the presence of signs consistent with local and systemic infection.	through study completion, an average of 1 year
