Exploring the effectiveness of a screening measure to identify subtle cognitive and functional problems in a sample of acquired brain injury patients admitted to a neurological hospital in the UK: A feasibility study

Abstract

Patients considered asymptomatic after acquired brain injury (ABI) may be exhibiting undetected cognitive deficits which can lead to problems with everyday tasks. Current screening tools focus on cognitive deficits and not functional impact. This cross-sectional feasibility study aimed to explore the use of a bedside screening tool: Cognitive Functional Performance Measure (CFPM). Drawing on occupational therapy theory and principles, the CFPM offers the multi-disciplinary team a unique tool to trigger referral to occupational therapy. A sample of patients with ABI (n = 34) were recruited and their CFPM scores were compared with scores on the Montreal Cognitive Assessment (MoCA) and the Kettle Test. Spearman’s rank and Chi-square were used to analyse the data. A moderate correlation was found between the MoCA and CFPM. There was no significant association between the type of ABI and performance on the CFPM. The unique design of the CFPM offers an alternative to existing screening tools, placing emphasis on the identification of cognitive impairment and functional deficits with the ultimate goal to develop a tool that is ecologically valid. Further studies exploring the feasibility and validity of the CFPM is recommended.
