BOOST-3 STUDY

The Stanford University is joining researchers at 45 other hospitals across the country to conduct a traumatic brain injury study called BOOST3. 

BOOST3 is a study involving patients who have had a severe traumatic brain injury. Traumatic brain injury, also known as TBI, is an injury to the brain caused by a blow to the head as may occur because of a fall or in a car accident. Patients with severe TBI are not conscious. A severe TBI is a life threatening medical emergency.

BOOST3 is a study to learn if either of two strategies for monitoring and treating patients with TBI in the intensive care unit (ICU) is more likely to help them get better. Both of these alternative strategies are used in standard care. It is unknown if one is more effective than the other. Patients usually must consent to be in a medical study. The patients in this study will be unconscious and unable to consent for themselves. If a family member or representative of the patient is not available to decide for the patient, a patient may be enrolled in this study without consent. Because of this we are asking community members to think about this research and let us know what you think about the study. 

A serious traumatic brain injury (TBI) can affect a person’s ability to think and remember things. It can prevent a person from returning to work or functioning independently. TBI can cause permanent brain damage or even death.

BOOST3 is a research study designed to learn if either of two alternative strategies for monitoring and treating patients with TBI in the intensive care unit (ICU) is more likely to help them get better. Participants in this study are put at random, that is by chance, in one of 2 groups. One group has medical care based on monitoring of pressure in the brain (intracranial pressure or ICP) alone. The other group has medical care based on both ICP and the amount of oxygen in the brain (brain tissue oxygen or PbtO2).

It is unknown if measuring and treating low brain oxygen is more effective, less effective, or the same as monitoring and treating high brain pressure alone. Treatment differs by group because doctors make decisions guided by ICP and PbtO2 goals. These decisions include the kinds and doses of medications given. They also include the amount of fluids given by vein.

Other treatments that may differ can also include changing ventilator (breathing machine) settings, blood transfusions, and other parts of medical care. ICP and PbtO2 are monitored by small sensors placed in the brain through one or two small holes made in the skull. Placing one or both of these monitors is standard care for people with severe TBI. They are placed within hours of arrival at the hospital. Those in the study will have both monitors placed.

Both of these alternative strategies are used in standard care at the study hospitals. In both strategies, doctors monitor the patient’s brain and modify the medical care provided in order to try to improve some measure of the brain’s health. However, it is not known which measure of the brain’s health, intracranial pressure or oxygen level, is more important. The results of this study will help doctors discover if one of these methods is more safe and effective.

Normally, researchers get permission (consent) before a person can be included in a study. A person with a severe TBI, however, will be comatose. Patients with severe TBI will not be able to give consent at the time of injury. When possible, consent to participate in the study is sought from the family member or legal representative of a patient with severe TBI before including the patient in a study. However, since emergency care for a patient with severe TBI must start quickly, there might not be enough time to locate and talk to the person’s family member or legal representative about the study. In this situation, a patient with severe TBI might be enrolled in this study without his/her family member or representative providing consent. This is called Exception from Informed Consent (EFIC) for emergency research. Once the family member or legal representative is located, they will be asked to give their permission for the patient with severe TBI to continue in the study.

The U.S. federal government has created a set of special rules for exception from informed consent for emergency research. EFIC can only be used when: 

  • The person’s life is at risk, AND, 
  • The best treatment is not known, AND 
  • The study might help the person, AND 
  • It is not possible to get permission: 
  • from the person because of his or her medical condition nor 
  • from the person’s guardian because there is a very short amount of time required to treat the medical problem
