Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

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
digital chest drain system for use in traumatic pneumonia/haemthorax. This drain will be connected directly to the intercostal catheter (ICC) in the same way as the current analogue drain is. Members of the trauma team (RNs or doctors) connect this train as part of the procedure when inserting an ICC. The duration of the ICC insertion / drain is dependent upon the lung reinflating, but is usually 2-3 days.
Review of electronic medical records will be used to determine this. All data will be available from the EMR. Although the digital drain offers further data (e.g. air leak) it will not be used as part of the study as comparable data can not be collected for analogue drains.

Statistical methods / analysis
The sample size calculation for the primary outcome (the total time in minutes of thoracic catheterization) has conservatively chosen the larger standard deviation value of 2.73 days observed in Pompili19. Based on the mean time of insertion of 3 days, and the standard deviation of 2.73 days, with significance level at 5% and power at 80%, a sample size of 118 participants per treatment arm is required to detect a clinically meaningful effect size of 1 day. Accounting for possible dropout rate of 10% a target total sample size of 262 participants will be required.
The distribution of baseline data will be presented by intervention arm. Continuous baseline data that is normally distributed (e.g. age) will be presented as mean ± standard deviation (SD), and non-normally distributed data (e.g. pre-hospital times) as median and interquartile range (IQR). Categorical data (e.g. sex of patient) will be presented as frequency and proportions.
The primary outcome will be analysed using the two-sample t-test and presented as the mean difference in total minutes of ICC insertion when the Thopaz drain was used compared to the Atrium. The 95% confidence interval and p-value for this difference will be presented.
Although it is expected that most patients will survive until removal of the ICC and to leave hospital, a secondary analysis will be performed on survivors.
The length of stay in hospital and in ICU will be compared between the intervention and control groups. This is expected to be positively skewed and will be presented as median (inter-quartile range) and compared using quantile regression. The number of ICCs, CXRs, and adverse events in each intervention group will be presented as frequency and proportions.
