In 2019, an article in a pharmaceutical journal reported that patients were being put at risk by most adult patients not having their intravenous (IV)-giving sets flushed. This had been brought to light through a patient safety forum and was quite the scandal. As chair of the National Infusion and Vascular Access Society (NIVAS), and a nurse practitioner for IV therapy at the time, I was a little confused about this. Although my formal IV therapy training had been nearly 20 years ago, I had no recollection of being taught to flush the IV-giving set after the infusion bag was empty. I asked around and confirmed that, apart from oncology and paediatrics, this was certainly not common practice in adult nursing in the UK.
