There is a range of risk factors that can lead to peripheral intravenous (IV) cannula failure, and several failed cannulation attempts can result in the patient experiencing increased pain, discomfort and delays in receiving IV therapy. The Vessel Health and Preservation (VHP) framework is a tool that can be used to improve clinical decision-making and the patient experience in relation to vascular access and IV therapy. Use of the VHP framework can ensure the right vein and right vascular access device (VAD) is selected at the right time for each patient. This article describes how healthcare practitioners can use the VHP framework to support and enhance vein assessment and VAD selection. It outlines the various types of VAD available, focusing on short-term peripheral IV cannulae, which are the most commonly used devices. It also explores the potential benefits of implementing the VHP framework in clinical areas.
