About this study

Pleural infection is a potentially serious infection of the fluid normally found around the lung and current evidence suggests its incidence is increasing in both adult and paediatric populations.

Identification of bacterial pathogens causing pleural infection is of paramount importance in the clinical care of patients are currently, only 40% of patients have a laboratory confirmed microbiological diagnosis for their pleural infection. An unclear diagnosis can be due to various reasons such as a small sample volume therefore the aim of the AUDIO study is to ascertain the capacity of pleural biopsies in improving the microbiological yield of pleural infection.

Currently, there are no well validated methods for identifying patients presenting with pleural infection on the basis of initial ultrasound imaging. The AUDIO study will define the role of baseline thoracic ultrasound in predicting the radiographic, clinical and surgical outcomes of patients with pleural infection.

The AUDIO study aims to recruit 50 patients from 2 centres with specific pleural expertise and these patients will be followed up over a 12 month period. Investigators hope that through the information gathered from ultrasound imaging and pleural biopsies, it will aid physicians' clinical and therapeutic decision making when treating patients with pleural infection.

Pleural biopsy sampling, Ultrasound

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Pleural biopsy samplingProcedure or surgery

    6 - 8 pleural biopsy samples will be taken before the insertion of the chest drain. These samples will be sent to microbiology for examination.

  • UltrasoundOther

What is being measured

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

  1. To increase microbiological yield.

    Measured: Positive microbiological results on pleural biopsy at baseline compared with positive microbiological results on pleural fluid.

Secondary outcomes (5)
  1. Radiographic improvement in area of pleural collection measured by the percentage of the ipsilateral hemithorax occupied by effusion on chest radiography.

    Measured: Day 1 and Day 7

  2. Mortality from pleural infection

    Measured: 3 and 12 months

  3. Duration of hospital (in patient) stay

    Measured: From the date of initial hospital admission to the date of discharge assessed up to 2 weeks.

  4. Necessity for surgical fluid drainage documented in case report forms over study completion

    Measured: 3 and 12 months

  5. Pleural fluid drainage over 7 days

    Measured: First 7 days of trial involvement

Questions about this trial

What is this clinical trial studying?

A study testing Pleural biopsy sampling and Ultrasound in people with Pleural Infection, run by University of Oxford at 2 sites in United Kingdom.

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 8 inclusion and 5 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 16 May 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United Kingdom. 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?

To increase microbiological yield. (time frame: Positive microbiological results on pleural biopsy at baseline compared with positive microbiological results on pleural fluid.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 16 May 2017.
