Sampling method: NON_PROBABILITY_SAMPLE
Study population: During the study period, 1,588 consultations were recorded in the unit for VAD cannulation, originating from various hospitalisation units.A non-probabilistic convenience sampling method was employed, and all patients over the age of 18 who were admitted to a hospitalisation unit and required VAD cannulation for intravenous treatment or due to poor venous access were included in the study, in accordance with the hospital's insertion criteria protocol. Patients who underwent the initial assessment but for whom cannulation was not attempted were excluded from the study.Cannulations were performed according to a checklist and with the assistance of ultrasound as a guiding technique.The VAST was created within an IVR service, with specific characteristics and the possibility of being able to channel the VADs in a room with a laminar ventilation system and a fluoroscope arch.

Brief summary: A study will be carried out to observe catheters (polyurethane tubes inserted into veins) over a period of five years. The study will look at any problems related to these devices, especially those put in at a specific hospital unit (vascular interventional radiology service) of the Arnau de Vilanova hospital in Lleida (Catalonia, Spain).

Detailed description: Introduction: Vascular Access Specialist Teams (VAST) have been implemented in numerous hospitals worldwide with excellent results. Although these vary in structure and function the purpose is the same in all of them, the improvement in cannulation and comprehensive cures of vascular access devices (VADs) based on the best scientific evidence.

Hypothesis: The creation of a VAST within an Interventional Vascular Radiology (IVR) service reduces the main complications related to VADs and contributes to improving the quality and safety standards necessary in the implantation and treatment of these devices Objective: To describe the creation of a VAST within an IVR service in a second level hospital. In addition, it is expected to analyze the prevalence of VADs placement and success rate, to determine the number of catheter-related bacteremia's and to know the number of failures of VADs cannulated in the EIAV in acute hospitalized patients.

Methodology: Retrospective observational study. A description will be made of the characteristics of the VAST, the implanted VADs and the main associated complications.

Expected results: We expect to describe the structure of a VAST within an IVR service and to analyze the prevalence of VADs placement and success rate, to determine the number of catheter-related bacteremia's and to know the number of failures of VADs cannulated in the VAST in acute hospitalized patients.

Clinical implication: The study will help to improve current VAST and to reduce the difficulties in the creation of future VAST, as well as to clarify the need for these specialized teams, which aim to improve the quality and safety standards necessary for VADs implantation and treatment.

Eligibility criteria: Inclusion Criteria:

* Patients over 18 years of age
* Admitted to a hospitalisation unit
* Requiring VAD cannulation for intravenous treatment or due to poor venous access, in accordance with the protocol of insertion criteria of the hospital.

Exclusion Criteria:

- Patients who underwent initial evaluation and cannulation was not attempted are excluded.

Primary outcomes:
measure: Incidence of complications that result in the malfunction of venous catheters cannulated using the ultrasound-guided technique in an interventional vascular radiology unit, necessitating their removal or replacement.
timeFrame: From date of study entry (day of catheter insertion) to the day of withdrawal from any cause, evaluated up to 111 weeks.
Secondary outcomes:
measure: Number of catheter-related bloodstream infections (CRBSI)
timeFrame: From date of study entry (day of catheter insertion) to the day of withdrawal from any cause, evaluated up to 111 weeks.
measure: Provide the success rate of ultrasound-guided cannulation of vascular access team.
timeFrame: From date of study entry (day of catheter insertion) to the day of withdrawal from any cause, evaluated up to 111 weeks.
