Abstract:
Introduction: Multiple punctures during peripheral venous catheter (PVC) placement increase the risk of complications. Scoring for adult difficult intravenous access (A-DIVA Scale) exists but has never been assessed in the framework of a care algorithm (scoring associated with a new decision-making tree for puncture conditions, the A-DIVA Tree). We seek to implement an catheter placement algorithm to decrease the mean number of punctures per patient. The algorithm will be adjusted based on obstacles and levers revealed by the analysis of clinical data. The benefits of the algorithm will be assessed using a step-by-step implementation of the approach.
Methods and analysis: 794 PVC placements will be recorded in two inclusion centres (50%/50%). In phase I, 297 PVC placements will be collected, and 16 individual semistructured interviews will be conducted to evaluate the centres’ practices. In phase II, 200 PVC placements will be recorded to assess the impact of the A-DIVA Scale alone. The interphase will allow preliminary results based development of the A-DIVA Tree. In phase III, 297 PVC placements will be recorded to assess the impact of the algorithm on the mean number of punctures per patient.
Ethics and dissemination: The study and related consent forms were approved by an institutional review board (Comité de Protection des Personnes Sud-Méditerranée I) on 25 April 2023 under reference number 2023-A00223-42. The results will be disseminated in the form of original articles, presentations and guidelines.
Trial registration number: NCT05935228.
