Risk factors associated with complications that required the removal of peripherally inserted central venous catheters in a tertiary pediatric hospital

Abstract

Background

In pediatrics, complications of the peripherally inserted central venous catheters (PICC) are reported in 30-40% of the cases, being the age of the patient and the location of PICC the most frequent risk factors. This study aimed to describe the characteristics of PICCs and to identify factors related to their withdrawal due to complications.

Methods

A prospective cohort study was conducted. Patients from 2 months to 18 years of age were included and followed-up until PICC was withdrawn. Age, sex, medications administered, PICC location, caliber, the number of lumens, days PICC was on the patient, and the reason for withdrawal was recorded. Univariate and multivariate analyses were performed.

Results

Two hundred and twenty-five patients were included. In 33.02%, PICC was withdrawn due to complications. In the bivariate analysis, age and location were factors associated with complications. A Cox proportional hazards model was performed. Only the caliber thickness (hazard ratio (HR): 0.5, confidence interval (CI) 95%: 0.35-0.99) was associated with any complication, and age (HR: 1.02, CI95%: 1-1.04) to the withdrawal of PICC due to suspected phlebitis.

Conclusions

PICC withdrawal due to complications was performed in 33% of the patients. Risk factors related to complications were PICC caliber thickness and age.
