What is the primary role of the IRF-PAI in TBI assessment?

• A. It assesses patient functional abilities and goals
• B. It measures only cognitive test scores
• C. It replaces all other neuropsychological assessments
• D. It is used to prescribe medications

Answer: (A)

The primary role of the IRF-PAI in TBI assessment is to capture how functionally independent a patient is and what rehab goals are being pursued, to guide treatment planning, intensity, and outcome measurement. It goes beyond cognitive testing by assessing everyday activities across domains like self-care, mobility, communication, and social functioning, translating those abilities into a functional score that informs how aggressively rehab should proceed and what outcomes to target. It does not replace other neuropsychological assessments, which explore cognitive processes in more depth, and it is not used to prescribe medications. In practice, the IRF-PAI data support admission and discharge planning and influence payment considerations within inpatient rehabilitation programs.
