Comparison of Computerised and Pencil-and-Paper Neuropsychological Assessments in Older Culturally and Linguistically Diverse Australians.

OBJECTIVES: Computerised neuropsychological assessments (CNAs) are proposed as an alternative method of assessing cognition to traditional pencil-and-paper assessment (PnPA), which are considered the "gold standard" for diagnosing dementia. However, limited research has been conducted with culturally and linguistically diverse (CALD) individuals. This study investigated the suitability of PnPAs and CNAs for measuring cognitive performance in a heterogenous sample of older, Australian CALD English-speakers compared to a native English-speaking background (ESB) sample. METHODS: Participants were 1037 community-dwelling individuals aged 70-90 years without a dementia diagnosis from the Sydney Memory and Ageing Study (873 ESB, 164 CALD). Differences in the level and pattern of cognitive performance in the CALD group were compared to the ESB group on a newly developed CNA and a comprehensive PnPA in English, controlling for covariates. Multiple hierarchical regression was used to identify the extent to which linguistic and acculturation variables explained performance variance. RESULTS: CALD participants' performance was consistently poorer than ESB participants on both PnPA and CNA, and more so on PnPA than CNA, controlling for socio-demographic and health factors. Linguistic and acculturation variables together explained approximately 20% and 25% of CALD performance on PnPA and CNA respectively, above demographics and self-reported computer use. CONCLUSIONS: Performances of CALD and ESB groups differed more on PnPAs than CNAs, but caution is needed in concluding that CNAs are more culturally-appropriate for assessing cognitive decline in older CALD individuals. Our findings extend current literature by confirming the influence of linguistic and acculturation variables on cognitive assessment outcomes for older CALD Australians.

Communication support needs assessment in dementia (CoSNAT-D): An international content validation study.

The decline of language and communication abilities is common among people living with dementia and impacts on many areas of everyday life, including active participation in social activities and decision-making. Despite a growing body of supporting evidence for approaches that address language and communication decline in dementia, the concept of communication rehabilitation is largely neglected in this population. This paper reports on the content validation of a novel tool, the Communication Support Needs Assessment Tool for Dementia (CoSNAT-D). The tool has been developed to assist in the initial identification of communication difficulties and related support needs of people living with dementia. Importantly, the CoSNAT-D is the only available tool that takes a three-way informed approach, considering the view of the person living with dementia, their carer and an administering healthcare professional. Content validity was established between September and December 2018 using a modified Delphi approach. An international expert panel rated 32 items of a face-validated item pool regarding their importance and relevance through an iterative feedback process. Consensus was pre-determined at 70% of agreement for both importance and relevance of an item. Data were analysed using descriptive statistics and qualitative content analysis of comments provided in each round. Twenty-eight experts working in dementia, language and communication participated in the Delphi survey. Qualitative analysis resulted in the addition of five items, of which three reached the required consensus in Round 3. Consensus was established for 35/37 items in three rounds. The pilot version of the CoSNAT-D demonstrates adequate content validity and face validity. The use of the CoSNAT-D may assist a range of healthcare professionals in the decision-making process about appropriate next management steps, and thereby improve the care path for people with dementia and language and communication impairment. The establishment of further psychometric properties is warranted.

Development of a new tool for the early identification of communication-support needs in people living with dementia: An Australian face-validation study.

Language and communication difficulties are common in dementia but limited tools are available for a timely assessment of those individuals who experience these difficulties. The Communication-Support Needs Assessment Tool in Dementia (CoSNAT-D) was developed to assist in (a) the early identification of communication difficulties among people with dementia in the community context; and (b) determining the level of their communication support needs to guide appropriate service access. The CoSNAT-D was developed based on a literature review. The face validity was tested with end-users (people with dementia and support persons of people with dementia) regarding relevance, wording, syntax, appropriateness and comprehensiveness of the items of the tool. Data were collected using semi-structured phone interviews. Seven people with dementia and 15 carers participated in the study. Feedback regarding items' appropriateness was largely positive and minor changes were made to improve comprehensiveness. A new item was added to the original item pool. The interviews highlighted the importance of including people with dementia in the assessment processes and person-centered approaches in this context. The CoSNAT-D presents a first step for the early identification of individual support needs of people living with dementia and communication difficulties who live in the community. Items of the CoSNAT-D have been determined face-valid by end-users. The face-validated version of the tool is currently undergoing further testing to determine additional relevant psychometric properties.

Prevalence of vitamin D supplement use in Australian residential aged care facilities in November 2014.

OBJECTIVE: We sought to establish the prevalence and predictors of adequate vitamin D supplement use, as per current falls prevention guidelines in Australian aged care homes. De-identified medication chart data from November 2014 were collected from pharmacists. The proportion of residents prescribed vitamin D and associations between adequate vitamin D supplementation and state, calcium use and osteoporosis medication use were assessed. RESULTS: The prevalence of adequate vitamin D supplement use (≥800 IU) was 47.1% of residents (95% CI 41.4, 52.8%). There was no significant difference between states (p = 0.3), however there was large variation between individual facilities (15.9-85.0%). Residents were more likely to be prescribed an adequate dose of vitamin D if they were prescribed a calcium supplement (p = 0.0001) or an osteoporosis medication (p = 0.03).
