Frequency of Peripheral Intravenous Catheter-Related Complications and Influencing Factors in Hospitalized Adult Patients.

Aim: The aim of this study was to determine the incidence and influencing factors of complications associated with peripheral intravenous catheterization in adult patients.Material and Method: This descriptive, cross-sectional, and observational study was conducted with 303 patients who agreed to participate in the research between December 2025 and February 2026. Data were collected using the “Sociodemographic Data Form” and the “PIVC Application and Potential Complication Monitoring Form”. Analyses included means, standard deviations, percentages, chi-square for intergroup comparisons, and Pearson correlation analysis to determine relationships between peripheral intravenous catheter-related complications and influencing factors.Results: In this study, the mean age of the patients was 59. Thrombophlebitis was found in 16.5% of patients who underwent peripheral intravenous catheterization. While a low-level positive correlation was found between catheter care and pain and thrombophlebitis development, a strong positive correlation was found between pain and thrombophlebitis development (p
