Validation and Refinement of the Adult Difficult Intravenous Access Score: A Clinical Prediction Rule for Identifying Adult with Difficult Intravenous Access
The Adult-Difficult Intravenous Access (A-DIVA) score, a proportionally weighted five-variable (vein palpability, vein visibility, vein diameter <2mm, history of difficult IV access and emergency surgery) clinical rule, has been developed to predict failure of intravenous (IV) placement in adult. This study sought to externally validate and reﬁne the A-DIVA score.
