Overview
The aim is to determine the prevalence of catheter-related thrombosis (CRT) in hospitalized patients carrying PICC, FICC, CICC, and midline catheters through a multicenter, standardized prevalence study. To achieve this, a cross-sectional study with prospective data collection will be conducted, including, through consecutive sampling to minimize selection bias, all hospitalized patients over 18 years of age from both general wards and critical care units who have had one of these catheters in place for at least 7 days. During data collection, an ultrasound examination of the catheter insertion site will be performed in order to rule out the presence of thrombotic complications.
Primary outcome measures
- Overall prevalence of catheter-related thrombosis [Time frame: From the beginning of the cutoff to the end of the cutoff at 4 weeks]
Secondary outcome measures (7)
- Symptomatic CRT [Time frame: From the beginning of the cutoff to the end of the cutoff at 4 weeks]
- Asymptomatic CRT [Time frame: From the beginning of the cutoff to the end of the cutoff at 4 weeks]
- Superficial CRT [Time frame: From the beginning of the cutoff to the end of the cutoff at 4 weeks]
- Deep CRT [Time frame: From the beginning of the cutoff to the end of the cutoff at 4 weeks]
- Prevalence by responsible service [Time frame: From the beginning of the cutoff to the end of the cutoff at 4 weeks]
- Time from implantation to CRT diagnosis [Time frame: From the beginning of the cutoff to the end of the cutoff at 4 weeks]
- Distribution by implanting operator [Time frame: From the beginning of the cutoff to the end of the cutoff at 4 weeks]
