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The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.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

Description of intervention(s) / exposure
The purpose of this trial is to assess the agreement between different groups performing critical care echocardiography. The three participant groups are sonographers, junior clinicians and senior clinicians. From each participant group, 3 will be randomly selected (via a random number generator) to perform a focussed transthoracic echocardiogram on a consented intensive care patient. These studies are expected to take approximately 15 minutes in duration (scanning time). The studies will be performed sequentially, all within a limited time frame of each other (target of 4 hours [half a day]) to have all of the studies performed on any given patient.
The echocardiographic findings will not be used to guide patient care but are instead being used to assess agreement and reliability across the three participant groups.

Comparator / control treatment
There is no gold standard for this study however it is likely that the sonographers will have the highest agreement therefore they are the control group and the clinician groups will be the comparator groups.

Summary
Brief summary
This study aims to compare the agreement in echocardiographic findings between and within three defined groups: cardiac sonographers, junior clinicians and senior clinicians, when performing transthoracic echocardiography on critically unwell patients. This information is vital when comparing scans performed by different operators and making clinical decisions based on the differences between the two scans.
