Analysis of complications associated with peripherally inserted central venous catheters. Prospective observational study.

INTRODUCTION

Vascular access teams often use guidelines or algorithms to determine the most appropriate vascular access device based on the patient's condition and the substance to be infused. These guidelines are intended to help identify the most qualified personnel for device insertion, but few studies collect information on the performance of these units.

OBJECTIVE

This study aims to identify the evolution and complication rate of peripherally inserted central catheters (PICCs) in patients requiring vascular access.

MATERIALS AND

METHODS

A prospective observational study was conducted over three years. Continuous variables with normal distribution were compared using Student's t-test. Nonparametrically distributed variables were analyzed with the Mann-Whitney U test. For categorical variables, the two-tailed chi-square or Fisher's exact test was used. Regression analysis was performed for the dependent variable of complications.

RESULTS

Of the PICCs inserted, 61.99% (566) were in patients receiving oncologic treatment, with a mean dwell time of 136±127.51 days. PICCs inserted in hematologic patients had a mean dwell time of 144±141.3 days (p=0.438). The most frequent complications were accidental removal (3.50%, 32, OR 0.581), thrombosis (3%, 27, OR 0.752), and central line-associated bloodstream infection (CLABSI) (2.10%, 19, OR, 0.113).

DISCUSSION: Complications related to PICCs were infrequent, with thrombosis being the most prevalent. Accidental removal was also frequent, a complication not thoroughly analyzed in other studies.

CONCLUSIONS

PICC insertion and management by vascular access teams enables units to achieve a low complication rate in onco-hematological patients.
