Verifying the Japanese version of the Healthy Aging Brain Care Monitor self-report tool for evaluating post–intensive care syndrome

Abstract

BackgroundPost–intensive care syndrome (PICS) requires the use of multiple assessment tools because it affects multiple domains: Cognitive, Functional, and Behavioural/Psychological. Therefore, this study translated the self-report (SR) version of the Healthy Aging Brain Care Monitor (HABC-M), spanning multiple domains, into Japanese and analysed its reliability and validity in a post–intensive care setting. MethodsPatients aged 20 years or older and admitted to the adult intensive care unit from August 2019 to January 2021 were included and surveyed by questionnaire. The 21-item Dementia Assessment Sheet for the Regional Comprehensive Care System was used to validate cognitive and physical aspects, and the Patient Health Questionnaire-9, the Generalized Anxiety Disorder-7, and the Post Traumatic Stress Disorder Checklist for Diagnostic and Statistical Manual of Mental Disorders 5th edition were used to validate emotional aspects. Reliability was assessed by Cronbach's alpha, and congruent validity by correlation analysis. Multivariate linear regression models were used to identify potential factors for PICS. ResultsA total of 104 patients (mean age: 64 ± 14 years) with 3 median mechanical ventilation days (interquartile range: 2–5) were enrolled. The Cognitive domain of the HABC-M SR was highly correlated with memory and disorientation (r = 0.77 for each), while the Functional domain was highly correlated with Instrumental Activities of Daily Living Scale (r = 0.75–0.79). The Behavioural/Psychological domain highly correlated with the Patient Health Questionnaire-9, Generalized Anxiety Disorder-7, and Post Traumatic Stress Disorder Checklist for Diagnostic and Statistical Manual of Mental Disorders 5th edition (r = 0.75–0.76). Multivariate analysis revealed longer ICU stays associated with lower Cognitive and Functional (p = 0.03 for each) domains and longer mechanical ventilation days with a lower Behavioural/Psychological domain (p < 0.01). ConclusionThe translated Japanese HABC-M SR showed high validity for assessment of the Cognitive, Functional, and Behavioural/Psychological domains of PICS. Therefore, we recommend that the Japanese version of the HABC-M SR be routinely used in the assessment of PICS.
