Aims: To determine the prevalence of recognised cognitive impairment amongst older adults attending a hospital-based diabetes clinic
Methods: This was a single centre retrospective cross-sectional study, in collaboration with the diabetes clinic of a tertiary metropolitan hospital. Stakeholder meetings identified a database of routinely collected patient information, wherein recognised cognitive impairment would be recorded. This data was obtained for all adults aged over 60 years old who attended the clinic from March 1 to August 1, 2020. Duplicate attendances were removed. Both an automated and manual search was undertaken to identify any record of cognitive impairment. Extracted data were analysed using simple descriptive statistics.
Results: Of 582 older adults, there were 6 (1.02%) patients with recognised cognitive impairment (table 1). The recorded diagnoses were: “dementia” (n=4), “cognitive impairment” (n=1), and Lewy Body Dementia (n=1). Concerns related to memory or cognition were noted in a further 8 patients, that did not constitute a recognised diagnosis (table 2). There were no recorded instances of mild cognitive impairment. Between-group comparisons were not possible due to the unexpectedly low prevalence of cognitive impairment identified.
Conclusions: Cognitive impairment was recognised less frequently than expected in older adults attending the diabetes clinic. Compared with the expected prevalence (between 29% and 74%[1-4]), this suggests a large pool of adults with unrecognised cognitive impairment. This presents a rich opportunity for quality improvement, and supports the case for routine screening for cognitive impairment amongst older adults attending the diabetes clinic. Based on evidence-based models of geriatrician-led collaboration in other specialty areas[5-11], a possible screening pathway is outlined (figure 1).
