Impact of Implementing the Modified A-DIVA Scale on Successful Access to a Venous Line on the First Attempt

Condition(s) studied

Investigational drug(s) / intervention(s)

Training in the A-DIVA scale and its failure prediction score: Nurses are trained in the A-DIVA scale and its predictive failure score. This score enables them to adapt their approach to peripheral venous line insertion.

Study summary

Peripheral venous access (PVA), although commonly used, can be a difficult procedure for patients with precarious venous capital. The difficulty of insertion can lead to multiple attempts, with the consequences of pain, anxiety, delayed management and worsening of the potentially already precarious venous capital. One study assessed the risk of failure according to a score based on venous status criteria. This study first established a link between venous status criteria and the risk of failure. The criteria defined as determinants were used to establish a venous status score. The data were then repeated by analyzing the success rate as a function of the scale score. A clear link between score and risk of failure was established. It seems worthwhile to evaluate the impact of implementing this scale prior to the placement of a peripheral venous line.

The hypothesis is that obtaining a score predictive of failure would modify the therapeutic attitude of the registered nurse. They would opt for techniques that would increase their chances of success. This in turn would lead to a reduction in unsuccessful attempts, which generate pain and anxiety for the patient. Preserving venous capital by increasing first-attempt success is both a health issue for the patient and a guarantee of quality of care.

Eligibility

Primary outcome measure(s)

• Success rate of peripheral venous vein placement — 1 year
  Success rate of peripheral venous vein insertion on the first attempt in the 2 groups (group in which VVP insertion will be performed by nurses not trained in the A-DIVA score and group in which VVP insertion will be performed after score assessment by nurses trained in the A-DIVA score) expressed by the number of attempts equal to 1.
