Abstract:

OBJECTIVES: To determine (1) if more than 50% of patients with moderate to severe traumatic brain injury (TBI) who met study criteria can complete a battery of neuropsychologic tests in less than 75 minutes 2 to 6 weeks after injury regardless of posttraumatic amnesia (PTA) status; (2) which tests are most likely to be completed; and (3) range of scores obtained. DESIGN: Prospective multicenter observational study. SETTING: Acute inpatient neurorehabilitation hospitals. PARTICIPANTS: Screened 543 Traumatic Brain Injury Model System patients with moderate to severe TBI; 354 were tested at 2 to 6 weeks postinjury. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Percentage of patients able to complete the neuropsychologic tests in less than 75 minutes. RESULTS: Two hundred eighteen (62%) patients completed the battery in 66 minutes on average. Mean interval from injury to testing was 28.3+/-7.1 days. Tests completed with the highest frequency were California Verbal Learning Test-II, FAS, and animal naming. Performance was less impaired (P<.001 on="" all="" measures="" for="" patients="" who="" had="" emerged="" from="" pta.="" conclusions:="" approximately="" two="" thirds="" of="" screened="" were="" able="" to="" complete="" a="" brief="" neuropsychologic="" test="" battery="" at="" weeks="" postinjury="" regardless="" pta="" status.="" although="" out="" less="" impaired="" confusion="" did="" not="" preclude="" participation="" in="" the="" or="" prohibit="" assignment="" scores.="" early="" assessment="" after="" tbi="" is="" feasible="" even="" many="" are="" still="">
