N1 - Funding Information:
The authors would like to thank our three co‐researching ACCHS partners who generously agreed to participate in this extra nested study as part of the Let's CHAT Dementia project. We would also like to acknowledge the contributions from the Let's CHAT Dementia Indigenous Reference Group, who guided data collection processes to ensure cultural appropriateness, the Let's CHAT Dementia project management group and Professor Ngaire Kerse for valuable advice on a draft version of the manuscript. The Let's CHAT Dementia project is funded by the National Health and Medical Research Council of Australia. This nested study about medications formed the first author's (MH) Master student thesis in the Faculty of Medicine, Dentistry and Health Sciences, The University of Melbourne.

N2 - Background: Aboriginal and Torres Strait Islander people are ageing with high rates of comorbidity, yet little is known about suboptimal prescribing in this population. Aim: The prevalence of potentially suboptimal prescribing and associated risk factors were investigated among older patients attending primary care through Aboriginal Community Controlled Health Services (ACCHSs). Methods: Medical records of 420 systematically selected patients aged ≥50 years attending urban, rural and remote health services were audited. Polypharmacy (≥ 5 prescribed medications), potentially inappropriate medications (PIMs) as per Beers Criteria and anticholinergic burden (ACB) were estimated and associated risk factors were explored with logistic regression. Results: The prevalence of polypharmacy, PIMs and ACB score ≥3 was 43%, 18% and 12% respectively. In multivariable logistic regression analyses, polypharmacy was less likely in rural (odds ratio (OR) = 0.43, 95% confidence interval (CI) = 0.24–0.77) compared to urban patients, and more likely in those with heart disease (OR = 2.62, 95% CI = 1.62–4.25), atrial fibrillation (OR = 4.25, 95% CI = 1.08–16.81), hypertension (OR = 2.14, 95% CI = 1.34–3.44), diabetes (OR = 2.72, 95% CI = 1.69–4.39) or depression (OR = 1.91, 95% CI = 1.19–3.06). PIMs were more frequent in females (OR = 1.88, 95% CI = 1.03–3.42) and less frequent in rural (OR = 0.41, 95% CI = 0.19–0.85) and remote (OR = 0.58, 95% CI = 0.29–1.18) patients. Factors associated with PIMs were kidney disease (OR = 2.60, 95% CI = 1.37–4.92), urinary incontinence (OR = 3.00, 95% CI = 1.02–8.83), depression (OR = 2.67, 95% CI = 1.50–4.77), heavy alcohol use (OR = 2.83, 95% CI = 1.39–5.75) and subjective cognitive concerns (OR = 2.69, 95% CI = 1.31–5.52). High ACB was less common in rural (OR = 0.10, 95% CI = 0.03–0.34) and remote (OR = 0.51, 95% CI = 0.25–1.04) patients and more common in those with kidney disease (OR = 3.07, 95% CI = 1.50–6.30) or depression (OR = 3.32, 95% CI = 1.70–6.47). Conclusion: Associations between potentially suboptimal prescribing and depression or cognitive concerns highlight the importance of considering medication review and deprescribing for these patients.
