Abstract:
Introduction: Phlebitis due to peripheral intravenous cannulation is a common issue in hospitalized patients which leading to serious complications such as deep vein and pulmonary thromboembolism, and septicemia. Understanding the time to phlebitis onset and its predictors is of clinical importance. However, data on its incidence, contributing factors, and time of onset remain limited in Ethiopia. Given the scarcity of compressive studies conducted in Ethiopia and the critical knowledge gap on the incidence, predictors, and timing of phlebitis onset, this study is significant in advancing clinical practice by identifying the time to onset of phlebitis and its predictors among hospitalized patients with peripheral intravenous cannulation.
Method: A prospective follow-up study design was conducted on a sample size of 372 participants using structured interviews and observational checklists. Time to phlebitis onset was determined with the Kaplan-Meier method and log-log plots, while predictors were identified using Cox proportional hazards regression.
Result: The cumulative incidence of phlebitis was 39.25% (95% CI: 34.25%-44.41%), with a median onset time of 5 days (IQR 4-6 days). Whereas, the significant predictors were female sex (AHR = 1.58, 95% CI: 1.11-2.25), use of an 18-gauge cannula (AHR = 2.02, 95% CI: 1.20-3.41), receipt of a blood transfusion (AHR = 2.11, 95% CI: 1.14-3.91), and administration of potassium chloride (AHR = 1.93, 95% CI: 1.17-3.19) and vancomycin (AHR = 2.89, 95% CI: 1.73-4.83).
Conclusion: In this study, the incidence of peripheral intravenous cannula-induced phlebitis was high, with a lower median time of phlebitis onset. The key predictors were female sex, large cannula, receipt of a blood transfusion, and administration of potassium chloride and vancomycin.
