The aim of this project is to evaluate, in a prospective cohort of PICC line patients, adherence to the project and understanding of the messages.

The transmission of knowledge and the acquisition of skills by patients with this type of invasive device will enable them to play an active role in their own care, and could help to reduce the frequency of risks.

This project is part of a collaborative approach that includes the creation of a mobile application for therapeutic education and monitoring (application under development). The evaluation of the device will be the subject of a national PHRC with national structures (SPIADI and PRIMO). The aim is to create a city-hospital collaboration to improve risk management.

The ever-increasing use of central venous lines, including PICC lines, and the shift in medical practice towards ambulatory care, are making it increasingly complex to prevent the infectious and non-infectious risks associated with their use.

The involvement of numerous healthcare professionals within and outside the hospital, with varying levels of training, exposes patients to numerous complications, the incidence of which, depending on the device, ranges from 6 to 16%, and occur at the time of insertion (hematoma, pneumothorax, necrosis) or during use (infection, thrombosis, extravasation).

The transmission of knowledge and the acquisition of skills by patients wearing this type of invasive device helps to make the patient a player in his or her own care, and could help to reduce the frequency of risks. As part of a therapeutic education program, we aim to validate the communication tools and messages identified by a panel of French experts. These messages, together with the article published by Petit et al, have enabled us to draw up a skills reference framework for patients with a PICC line.

The aim of this project is to evaluate adherence to the project and understanding of the messages on a prospective cohort of patients.
