Patient-centred care and multidisciplinary issues - assessment of older patients with English as a second language

The problem

Assessing older patients who are not fluent in English (or with limited health literacy) requires adaptation of standard geriatric assessment tools and processes, since many cognitive and functional screening instruments are language- and culturally-dependent
A substantial proportion of older Australians were born overseas, and language barriers increase with age as English fluency (particularly for those who learned it as a second language) can decline alongside general cognitive changes, sometimes with earlier and more pronounced loss of a second language than a first

Cognitive screening tools (e.g. MMSE, MoCA) were largely developed and validated in English-speaking populations - direct translation does not preserve validity, since item difficulty and cultural relevance differ; culturally and linguistically appropriate normed tools (e.g. the Rowland Universal Dementia Assessment Scale, RUDAS, designed to be less culturally/language-biased) are preferred where available

Professional interpreters (not family members) should be used for clinical assessment wherever possible - family interpretation risks inaccurate translation, withheld information (embarrassment, protecting the family member), and blurred consent/capacity assessment
Assessment should account for educational background and health literacy, not language alone - low literacy in any language affects performance on many standard tools independent of true cognitive status

Allow additional time for interpreter-mediated assessment; where possible, use validated tools with established cross-cultural norms rather than translating a standard English-language tool on the spot
Engage culturally appropriate community supports/liaison services where available, particularly for ongoing care planning and family communication

Dementia diagnosis in culturally/linguistically diverse populations, health literacy, capacity assessment across a language barrier
Misdiagnosis (both under- and over-diagnosis of cognitive impairment) is a recognised risk when standard English-normed tools are applied without adaptation - the assessment method itself needs to be chosen deliberately, not simply performed through an interpreter using a standard instrument
