Predicting the future for patients with severe traumatic brain injury
A multidisciplinary team from the MUHC emphasizes better predictive tools and defines major trends in patient progress.
"How will our loved one come out of this?" After an accident that results in severe traumatic brain injury (sTBI), the answer to this simple question can change everything for a family.
The latest study carried out by Dr. Elaine deGuise, Joanne
Leblanc, Mitra Feyz and all the clinicians of the Traumatic Brain
Injury Program for Adults at the McGill University Health Centre
(MUHC) describes the tools that are most effective at providing an
objective answer to this question almost as soon as patients leave
intensive care. The study was published recently in the Journal of
Head Trauma Rehabilitation.
Better advice and more structured follow-up
"This study is unique as it involved a multidisciplinary team. We
could therefore assess the patient from many angles and establish
an overall picture," stated Dr. deGuise. "Our findings are
important because, in addition to the advice that we can give to
families, we can now implement a comprehensive program in the
continuum of care that is based on more objective and scientific
principles."
Powerful predictive tools
When patients with a sTBI leave acute care hospitals (generally
between 20 to 29 days after the accident), they undergo standard
tests to assess their overall level of functioning and to orientate
them to appropriate resources to optimize their recovery.
This study proves that their results can also be used to predict
the future development of the patient's general condition. The
tests used in this study include the GOS-E (Extended Glasgow
Outcome Scale), the NRS-R (Neurobehavioral Rating Scale-Revised),
and the FIM (Functional Independence Measure).
"The tests that are regularly performed on all our patients with a
sTBI are very effective tools as, based on their results, we can
give families an idea of the patient's incapacities and progress
after the trauma," J. Leblanc explained. "There are many factors
that influence post-traumatic recovery, but the measurement scales
are complex enough that we can make realistic predictions about
patients' future physical, cognitive or emotional states."
Persistent cognitive and emotional
deficiencies
The study was based on the follow-up of 46 patients from 2 to 5
years after an accident that led to a sTBI. The patients took the
GOS-E, NRS-R and FIM tests again for the study. The researchers
then compared their results with those from the same tests
performed when the patients were discharged from acute care
hospital.
The researchers found that these patients' physical function and
ability to perform daily tasks had improved over time. However,
their cognitive and emotional faculties, meaning their ability to
perform more complex tasks and to cope in society, did not develop
to the same extent.
"These cognitive and emotional deficiencies can have major
consequences: most of our patients could not keep the same job
after their accidents," said Feyz. "This leads to other
psycho-social problems that often result in psychological
vulnerability. Out of all the patients observed in this study, 52%
presented depressive or anxiety disorders two to five years after
the trauma."
The effects of a serious accident that leads to a sTBI are not
limited to patients alone: their friends and family members, as
well as the entire health care system, are also affected, which has
emotional and financial consequences. Prevention is still the best
way to manage these kinds of events.
