Trial summary

Totally implanted venous access ports allow a safe delivery of medication, mainly chemotherapy, but are also used for blood sampling. This last procedure is not always successful, as it appeared from a nurse's survey in different hospitals in Flanders, including the University Hospitals in Leuven, Belgium.

About this study

Official title: Functional Evaluation of Conventional Venous Access Port (Celsite®) Versus Venous Access Port With Tangential Outlet (Vortex®) : a Prospective Randomized Pilot Study

Totally implanted venous access ports allow a safe delivery of medication, mainly chemotherapy, but are also used for blood sampling. This last procedure is not always successful, as it appeared from a nurse's survey in different hospitals in Flanders, including the University Hospitals in Leuven, Belgium. In 3 to 29 percent of the attempts, blood withdrawal is impaired or not possible, as an intermittent or permanent fact. This is in line with international literature data where difficulty in blood draw was noted in 6 to 26% of port accessions. Partial or total occlusion leads to discomfort for the patient, delay in therapy, higher costs and extra nursing time.

A new port system with a tangential outlet (Vortex port) was designed and according to the manufacturer, this shape will allow to cleanse the entire reservoir of the port more efficiently and avoid the formation of precipitates of medication or blood that could lead to an obstruction of the device. These precipitates are also regarded as a potential risk factor for infection.

However, only one previously published small randomised study addressed the value of the Vortex port when compared to conventional access devices: Stevens et al. were able to show a reduction in obstruction incidence from 26% to 7% with the use of the Vortex port. The incidence of blood withdrawal problems in our experience with conventional ports in University hospitals Leuven was 8% thus lower than that reported by Stevens, but this remains the most frequent problem faced by care providers and patients.

With this study, the investigators aim to compare the performance of the tangential outlet ports and that of a "conventional" port in order to assess an eventual functional difference.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Evaluation of the difference in difficulty in blood drawing between the 2 types of ports when accessing the port under identical maintenance procedure according to the guidelines in the University Hospitals Leuven.

    Measured: up to a maximum of 6 months after insertion

  2. Evaluation of the difference in one-way or bidirectional occlusion incidence between these 2 types of ports, when accessing the port under identical maintenance procedure according to the guidelines in the University Hospitals Leuven.

    Measured: up to a maximum of 6 months after insertion

  3. Evaluation of the difference in filling time for blood sampling between these 2 types of ports when using a standard 10 ml vacuum blood tube and a 19 G Gripper® needle.

    Measured: immediately after insertion and up to a maximum of 6 months afterwards

Secondary outcomes (1)
  1. Evaluation of the ease of use (ease of access) between these 2 types of ports when accessing the port.

    Measured: up to a maximum of 6 months after insertion

Questions about this trial

What is this clinical trial studying?

A study testing Vortex port and Celsite port in people with Hematologic Disease, run by Universitaire Ziekenhuizen KU Leuven at 1 site in Belgium.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 26 Jan 2009. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Belgium. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Evaluation of the difference in difficulty in blood drawing between the 2 types of ports when accessing the port under identical maintenance procedure according to the guidelines in the University Hospitals Leuven. (time frame: up to a maximum of 6 months after insertion). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00484848, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Jan 2009.
