Prediction of Cognitive Abilities 1 Year Following Traumatic Brain Injury From Inpatient Rehabilitation Cognitive Screening.

Abstract

To evaluate the ability of the Cognitive Log (Cog-Log) to predict neuropsychological outcome at 1 year after traumatic brain injury (TBI). Study Design: The Orientation Log (O-Log) and Cog-Log were administered during morning rounds, and a battery of neuropsychological tests was administered at 1 year postinjury. Setting: Acute rehabilitation hospital. Participants: Fifty rehabilitation inpatients.Main Outcome Measures: Composite scores for processing speed, attention, language, memory, executive functioning, and visuospatial abilities. Results: The Cog-Log was found to significantly predict 1-year outcome in attention, executive functioning, and visuospatial abilities. The O-Log contributed significantly to memory outcome. The Disability Rating Scale was not a significant predictor. Conclusions: The Cog-Log has utility as a predictor of neuropsychological outcome, particularly when used with its companion instrument, the O-Log.

An Effort Index for the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS)

“…Examples include when abbreviated bedside evaluations are needed, serial tracking of global cognitive status, when quantification of global cognitive status is sufficient to address the referral question, to screen for brain dysfunction in at-risk populations, or to inform the need for and composition of a larger-scale battery. As such, they are frequently used in settings such as correctional facilities (Iverson, Franzen, Demarest, & Hammond, 1993), HIV clinics (Carey et al, 2004), substance abuse treatment programs (Grohman & Fals-Stewart, 2004), general hospital consultation-liaison psychiatric services (Serper & Allen, 2002), and inpatient rehabilitation centers (e.g., Lee, LoGalbo, Bañ nos, & Novack, 2004). Reflecting this need, a variety of population-specific and general-purpose screening batteries have been developed.…”

Cognitive Log performance among individuals without brain injury in an inpatient rehabilitation setting.

“…It is comprised of items measuring functions including orientation, verbal memory, attention, working memory, motor sequencing, time estimation, and response inhibition (Penna & Novack, 2007). The instrument was designed to provide information regarding the daily recovery process of cognitive abilities during inpatient rehabilitation among individuals with a recent brain injury, and it has also been shown to be predictive of 1-year outcomes following traumatic brain injury (TBI) in domains including attention, executive functioning, and visuospatial abilities (Lee, LoGalbo, Baños, & Novack, 2004). This is unique from other brief screening instruments because it is designed to be used serially to track progression of cognitive recovery.…”

A review of the use and psychometric properties of the Cognitive Log (Cog-Log) amongst adults with acquired brain injury.

“…Interrater reliability ranges from adequate to excellent, with Spearman’s rho coefficients between .749 and 1.0 1 . The Cog-Log has also been shown to have adequate internal consistency (Cronbach’s alpha = .778), 1 with excellent criterion validity, significantly correlating with the Mini-Mental State Examination ( r = .75) and O-Log ( r = .75) 3 . The Cog-Log has been shown to be significantly associated with other neuropsychological measures of memory, language, attention, and reasoning ( p = <.001–.004) 1 .…”

“…Due to the nature of the rehabilitation hospital setting, as well as the severe deficits in attention and concentration commonly seen in acutely brain-injured patients, brief bedside evaluation instruments that allow clinicians to quickly assess multiple cognitive domains are crucial. The Cognitive Log (Cog-Log) is a bedside screening measure for patients with acquired brain injury designed to assess orientation, verbal learning and recall, attention, working memory, motor sequencing, time estimation, and response inhibition 3 . Of note, the Cog-Log was intended to evaluate cognitive domains that heavily impact rehabilitation participation and outcome, as well as skills that may reflect early changes in cognitive functioning secondary to metabolic, pharmacologic, or neurologic sequelae 1 …”
