Traumatic Brain Injury

Traumatic Brain Injury (TBI): cerebral damage that occurs after birth, and is not directly related to a developmental disorder or a progressive damaging of the brain. Traumatic brain injury refers to a specific form of acquired brain injury that is the result of a sudden trauma.
Acquired Brain Injury (ABI): includes all types of traumatic brain injuries and also brain injuries caused after birth by cerebral vascular accidents (commonly known as stroke), and loss of oxygen to the brain (hypoxic brain injury).
Traumatic Brain Injury
Traumatic brain injuries are classified by severity into one of three categories: mild, moderate, or severe.
Classification into one of the three categories is usually based upon the following four criteria. Glasgow Coma scoreDuration of loss of consciousnessDuration of alteration of consciousnessSeverity of post-traumatic amnesia

Classification Guidelines
In 2003, approximately 1.5 million Americans experienced a traumatic brain injury.
Of those 1.5 million, 290,000 were hospitalized and 50,000 died.
62.3 per 100,000 adults age 15 and over
are living in the community with impairments due to brain injury.
Some Stats
Twice as many males are affected by TBI as females.
Ages 15-24 and >60 are at the highest risk.
Individuals in rural areas are more at risk.

Causes
Physical Causes
Bruising/Bleeding, Tearing, Swelling, Open/Closed injuries
Costs of traumatic brain injury in the U. S. have been estimated to be $48.3 billion annually.Survivors cost $31.7 billion.Fatalities cost $16.6 billion.
Lifetime cost per person is about $4 million.About 75% of patients with severe TBI do not
return to work.About 66% require assistance with daily living.90% report dissatisfaction with social
integration.
Costs
Prevalence rates for psychiatric disorders are high after TBI.Depression rates have been reported in 14 to 77% of patientsSubstance abuse 5 to 28%PTSD 3 to 27%Other anxiety disorders 3 to 28%
TBI and Mental Illness
Life satisfaction appears to steadily decline after an individual experiences a brain injury.
Injury severity has not been found to be significantly correlated with measures of life satisfaction.
TBI and Quality of Life
Many variables have been shown to correlate with life satisfaction in individuals who have suffered TBIs.Marital StatusEmploymentProblem Solving Executive Functioning

Goals of Rehabilitation
16
Purpose of Rehab
• The overall goal of Rehabilitation following a TBI is to improve the person’s served functioning at home.• This can be done by helping to restore a
client’s physical, sensory, psychological, or cognitive abilities, or by helping them develop compensatory strategies.
17
Cognitive: Cognitive Rehabilitation/Neuropsychology/Speech
Physical: Physical Therapy/Occupational Therapy
Emotional/Adjustment: NeuropsychologyParticipation: Entire team
Rehabilitation Focus
Immediate MemoryDigit SpanNot a Common Complaint
Short Term MemoryMost Common Deficit in TBI
Long Term MemoryMissing details due to STM loss
Memory (Cog and Neuropsych)
Aphasia CircumlocutionHand GesturesTip of the tongue
Common due to anatomy of skull
Language/Word Finding (Speech and Neuropsych
Ambulation/Motor (PT/OT)• Difficulties with balance/walking
• Impairments in fine motor skills
• Decreased strength and stamina
21
Headaches
Spinal Cord Injuries
Ineffectiveness of Pain Medication
Chronic Pain (PT/OT)
Brought on by large crowds, lots of noise, or information presented too quickly.Inability to process external environmentFatigue Rise in emotions
Overload (Neuropsych/OT)
Emotions can become flat or amplified. Lack of inhibitionTrouble analyzing social situations
Difficulty with facial expression or tone of voice
Emotions (Neuropsych)
Measuring Outcomes
25
Outcome Measures UsedWhat measures are used depends on
the setting (acute or long-term rehabilitation)
Acute settings frequently use:Functional Independence Measure (FIM): An 18-item scale used to
assess the patient's level of independence in mobility, self-care, and cognition
Glasgow Outcome Scale (GOS)Disability Rating Scale (DRS): Measures general functional changes
over the course of recovery after TBI
26
What about long-term?• No measures are universally agreed
upon
• Some measures frequently used include:• Mayo Portland Adaptability Inventory (MPAI)• Supervision Rating Scale (SRS)• Community Integration Questionnaire (CIQ)• Disability Rating Scale (DRS)• Independent Living Scale (ILS)And many more
27
Difficulties
• What outcomes are the most significant/important?• The goals of rehabilitation are individualized
making it difficult to identify a universal outcome
• The complexity of the cases makes it difficult to make causal references• Substance abuse, multiple treatment
modalities, social support, etc.
28

Questions about the accuracy of self-report
• Some researchers have found that in people who have suffered TBIs, self-report is not a reliable measure.• Language deficits • Awareness • Abstract Reasoning• Memory

Our Measures

Standardized MeasuresBancroft is a member of the Pennsylvania Association of Rehabilitation Facilities (PARF), a collaborative data collection and outcomes measurement project designed to:• Enhance clinical evaluation• Verify the treatment provided produces the desired outcomes• Allow providers to make better decisions regarding
program/service components• Provide aggregate data to funders to assist with evaluation of
needs and services
In conjunction with our PARF colleagues, we utilize three standardized outcome measures: Mayo-Portland Adaptability Inventory (MPAI-4, Malec, J., 2005); Supervision Rating Scale (SRS, Boake, C., 2001); and most recently the World Health Organization Quality of Life Index (WHOQOL-BREF, WHO, 2004). A project to develop standardized satisfaction surveys is in progress.
37
Outcomes Process
• Data is collected annually
• Data collection included an annual neuropsychological assessment
• Entire rehabilitation team is invloved
38
Supervision Rating Scale• Measures the level and type of
supervision that a patient/subject receives from caregivers
• The SRS rates level of supervision on a single 13-point ordinal scale
• SRS ratings have shown consistent relationships with type of living arrangement and with independence in self-care and instrumental ADL
39
40
WHOQOL-BREF• The WHOQOL-BREF instrument comprises 26
self-reported items, which measure the following broad domains: physical health, psychological health, social relationships, and environment
• Research has found that the WHOQOL-BREF has strong psychometric properties
• Raw scores on the measure can range from 24 to 120, with higher scores being indicative of a higher quality of life.

national database for MPAI-4 scores• Would allow different rehab centers to
combine data to study changes in outcomes over the course of post-acute rehabilitation

Difficulties and New Ideas
58
Challenges • Goals related to the abilities scale in the
MPAI-4 are difficult to obtain in a sub acute rehab population
• In general the MPAI-4 is useful for detecting significant long-term changes in functioning. Not as useful as an immediate measure of progress
• WHOQOL-BREF has robust findings, but still suffers from concerns over self-report.
59
Future Ideas
• Continue to explore how to measure satisfaction
• A specific measure of financial capacity
• Better measures of risk assessment
