BACKGROUND: Serious complications can develop from erroneous insertion of a peripheral intravenous catheter (PIVC). Successful PIVC insertion has a great place in the continuation of IV treatment without causing complications that may require the removal of the PIVC. METHODS: The population for this prospective observational study included patients who had undergone PIVC insertion in the surgical, intensive care, and inpatient units of a large teaching and research hospital in Istanbul. Data were collected via a patient information form, a PIVC and treatment information form, the Visual Infusion Phlebitis (VIP) scale, and a PIVC nurse observation form. The SPSS 24 software package was used to analyze the data. RESULTS: Of the 168 patients enrolled, 64.9% ( CONCLUSIONS: It was determined that PIVC dwell time could be increased by routine surveillance to monitor for phlebitis regularly. It is recommended that education programs for nurses be developed to prevent PIVC-related complications.
