Evaluation of A-DIVA Score Effectiveness at Admission for Preserving Venous Capital in Patients With Difficult Access

Randomized Controlled Clinical Trial Assessing the Effectiveness of a Venipuncture Strategy Adapted According to A-DIVA Score Results Compared to Standard Care in Reducing the Number of Punctures

In certain cases (e.g.: patient who are difficult to perfuse, thin veins, etc.), an increase in venipunctures performed by study nurses in healthcare services can lead to a loss of venous capital, repeated pain during punctures, discontinuous treatment follow-up and numerous requests for assistance from colleagues, including nurse anesthetists, but often too late.

The main objective of project is to reduce the number of punctures to access the venous system after evaluation of adult patients upon entering the hospitalization department using the A-DIVA tool. the A-DIVA score predicts the difficulty in infusing an adult patient

This research evaluates the importance of assessing the venous capital access of hospitalized patients prior to the placement of an intravenous infusion, in order to save time in initiating therapeutic treatment and to prevent or reduce the number of venipunctures and the associated inconveniences (pain, discontinuous treatment monitoring). This approach aims to preserve the patient's venous capital.

In the proposed study, investigators will evaluate the patients' venous capital using the Adult-Difficult IntraVenous Access (A-DIVA) tool upon hospital admission and during hospitalization before any peripheral intravenous (IV) catheter placement.

During the inclusion visit, after obtaining informed consent, patients will be randomized into one of two groups:

• Group A: Patients will undergo an evaluation of their venous capital by a study nurse using the Adult-Difficult IntraVenous Access (A-DIVA) tool prior to any peripheral IV catheter placement during hospitalization.
• Group B: Patients will not undergo an evaluation of their venous capital using the Adult-Difficult IntraVenous Access (A-DIVA) tool prior to peripheral IV catheter placement. They will receive standard care as routinely provided in the hospital ward.
