PRECISION-TBI - An Observational Study of Patients With Moderate to Severe Traumatic Brain Injury

Traumatic Brain Injury (TBI) is a devastating condition and a leading cause of long-term disability. Every patient with TBI has a different type of injury and is treated differently from hospital to hospital making it very difficult to identify the most effective treatments. The current study focuses on the most severe types of TBI that require hospital ICU care - moderate to severe TBI (m-sTBI). The overall aim of this study is to collect data about how different hospitals manage m-sTBI in Australia, and to quantify the variability that likely exists. Recovery at 6 months post-injury will be collected to allow a better understanding on how different injuries and treatments affect long term outcomes.

Traumatic Brain Injury (TBI) is a devastating condition and a leading cause of death and long-term disability, particularly in young adults. In Australia and New Zealand, severe TBI accounts for over 700 intensive care unit (ICU) admissions per year. Approximately half of these patients will die or be severely disabled six months after their injury. The lifetime costs for the disabled survivors of TBI reach an estimated $1 billion annually. There are strong ethical, medical, social and health economic reasons to improve treatment and reduce disability in TBI.

TBI is a broad term for many different types of injuries to the brain. This study focuses on the most severe types of TBI that require hospital management and ICU care - moderate to severe TBI (m-sTBI). The fact that every patient with m-sTBI is different, has a different type of injury and is treated differently from hospital to hospital makes it very difficult to study m-sTBI and identify the most effective treatments for improving patient outcomes. At the moment, there is only a small amount of data on how m-sTBI patients are treated in the different hospitals in Australia and whether there are differences in outcomes associated with different approaches to m-sTBI management. Currently there is no central database for m-sTBI patients in Australia that can be used to compare different hospitals and track progress over time.

The first aim of PRECISION-TBI is to collect data about how different hospitals manage m-sTBI in Australia, and to quantify the variability that likely exists. High quality data about the initial injury (cause, severity and presence of factors that may make the injury worse), the early management of the patient (e.g. time to arrival at hospital), the surgical management of the patient (surgeries undertaken and monitoring probes utilised), the clinical management in ICU and neurological outcome after the injury will be collected. The main focus will be on the ICU management of m-sTBI so participating sites will be provided with computers and specialist software to collect accurate minute to minute data from brain monitors used to guide patient management in the ICU. Recovery at 6 months post-injury will be collected for all enrolled participants to understand how different injuries and treatments have affected long term patient outcomes.

The participating hospitals will also be provided with feedback on the characteristics of their m-sTBI patient population, the treatments that they are using and the outcomes for their patients. It will be possible for participating hospitals to compare each of these parameters with other similar hospitals and this will allow the identification of any factors that are strongly associated with improved patient outcomes. This will be provided over the course of at least 2 years, which will allow hospitals to track progress over time and identify how changes to management protocols and care systems may result in better outcomes for patients in this highly vulnerable group.
