National Study on the Prevalence of Catheter-Related Venous Thrombosis

NCT07643246 | Not Yet Recruiting

• 1 other identifier: TROMBO2025.109
• Study Type: observational
• Target: 500
• Locations: 0 countries
• Sites: N/A

Brief Summary

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.

Conditions

Thrombosis; Venous Catheterization

Outcome Measures

Primary Outcomes (1)

• Overall prevalence of catheter-related thrombosis

  Number of patients with CRT / total number of patients evaluated) × 100

  From the beginning of the cutoff to the end of the cutoff at 4 weeks

Secondary Outcomes (7)

• Symptomatic CRT

  From the beginning of the cutoff to the end of the cutoff at 4 weeks

• Asymptomatic CRT

  From the beginning of the cutoff to the end of the cutoff at 4 weeks

• Superficial CRT

  From the beginning of the cutoff to the end of the cutoff at 4 weeks

• Deep CRT

  From the beginning of the cutoff to the end of the cutoff at 4 weeks

• Prevalence by responsible service

  From the beginning of the cutoff to the end of the cutoff at 4 weeks

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

The study will be conducted across the following centers: Complejo Hospitalario Universitario Nuestra Señora de Candelaria, Hospital del Mar, Hospital Sant Joan de Déu-Althaia, Hospital Universitari Joan XXIII, Hospital Universitario de Navarra, Hospital Universitario Doctor Josep Trueta, Hospital Universitario Donostia, Hospital Universitario Mutua Terrassa, Hospital Universitario Son Espases, Policlínica Gipuzkoa, and Hospital de Navarra. Participation will include hospital institutions with an Infusion and Vascular Access Unit (IVAU) that has institutionally recognized expertise in the detection of catheter-related thrombosis (CRT).

You may qualify if:

• All hospitalized patients aged ≥18 years from all hospital wards, including critical care units, who are carriers of a midline, FICC, PICC, or CICC catheter with a dwell time of at least 7 days will be included.

You may not qualify if:

• Patients who do not provide informed consent for the ultrasound assessment.
