COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A 10 minute spontaneous breathing trial will be performed to assess patient respiratory drive prior to cessation of cardiorespiratory support. This will involve transferring patients from the ventilator to a T-piece device. If breathing rate falls below 10 breaths per minute or oxygen saturations drop by 10% the patient will be reconnected to the ventilator and a positive test result recorded. Otherwise, they will be reconnected to the ventilator after a 10 minute observation period and a negative result recorded
Intervention code [1] 298372 0
Diagnosis / Prognosis
Comparator / control treatment
Sensitivity and specificity of the DCD 10-10 test will be assessed by comparison with Staff Specialist opinion. Staff specialist opinion will be obtained following patient consent for the DCD process. It will be recorded onto the secure RedCap online data collection system and locked prior to the DCD 10-10 test being performed and the outcome of withdrawal of cardiorespiratory support recorded.
Control group
Active

Outcomes
Primary outcome [1] 305434 0
1. To assess the safety of performing a spontaneous breathing trial on a T-piece humidification system for 10 minutes in patients eligible for DCD. This will be done by looking for adverse outcomes in the time surrounding the DCD 10-10 test.
Adverse outcomes to be examined include: ventricular arrhythmia, cardiac arrest, prolonged desaturation (> 5 minutes taken to restore baseline ventilatory settings), severe hypotension (MAP < 60mmHg), failed donation opportunity (inability to continue organ retrieval). Outcomes will be assessed via monitoring at the bedside and documentation into an electronic database by the Organ Donor Coordinator. The rate of events will then be calculated.
Timepoint [1] 305434 0
For the 10 minute duration of the DCD 10-10 test, the 10 minute period following the DCD 10-10 test and the organ donation retrieval process (expected to occur within 1 hour of the DCD 10-10 test)
Primary outcome [2] 305519 0
2. The feasibility of performing the DCD 10-10 test, wit any failure to complete the test recorded.

The total amount of ionotrope and vasopressor medication administered in the hour prior to withdrawal of cardiorespiratory support and its ability to predict death within 90 minutes.

Eligibility
Key inclusion criteria
All patients who meet the GIVE trigger and have consented for DCD organ donation will be eligible for inclusion in the trial. Therefore, inclusion criteria will include patients whom are mechanically ventilated, with a Glasgow Coma Scale Score < 5, in whom end of life conversations have taken place.

Note: Patient’s receiving a high level of respiratory support (FiO2 > 60%, PEEP > 10) or haemodynamic support (combined vasopressor/ ionotrope requirement > 1microg/kg/min) will be eligible for enrolment in the study and will have all data collected, including Staff Specialist prediction of time to death. It will then be at the Staff Specialists discretion as to whether the DCD 10 – 10 test is necessary to perform.

Summary
Brief summary
This study aims to establish a simple, safe, bedside test to better determine which patients are most suitable for organ donation following circulatory death.

The DCD 10-10 test is a 10 minute spontaneous breathing trial which aims to determine respiratory drive in these patients, it is hypothesised that this test will be predictive of which patients will die within 90 minutes post withdrawal of cardiorespiratory support. This 90 minute time frame is essential for ensuring organ viability for donation.

The DCD 10-10 Pilot Study is a safety and feasibility trial on a small sample of patients, it aims to ensure the DCD 10-10 test is safe and can be easily performed in the organ donation setting. It will also test software used for data collection and gather some early descriptive statistics on the sensitivity and specificity of the test and patient factors that correlate to time of death.
