Abstract

Abstract: Funding Acknowledgements: Type of funding sources: None. Background: Diabetes is a well-known risk factor for cardiovascular diseases and continues to be a global public health challenge. In Australia, prevalence rates of diabetes increase with age with almost 1 in 5 older people reported being diagnosed with diabetes. Older persons with diabetes are also more likely to have multiple comorbidities adding to their complexity. A better understanding of comorbidity patterns and their associated factors in older people with diabetes is instrumental to identify groups of individuals that differ in healthcare needs, resources utilized, and health trajectories. Purpose: To identify comorbidity patterns in community-dwelling older adults with type 2 diabetes attending general practice settings in Australia. Methods: This is a cross-sectional study based on the Bettering the Evaluation And Care of Health (BEACH) data. The BEACH program was a continuous, national study of the state of general practice clinical activity in Australia from 1998 to 2016. As part of the program, General Practitioners (GPs) would collect additional patient information during patient visits through structured paper-based recording sheets. For the purposes of this sub-study, a random sample of 1800 participating GPs were invited to record all diagnosed chronic conditions for 30 consecutive patients over twelve five-weeks recording periods between November 2012 and March 2016. The dataset was analyzed with descriptive analysis and exploratory factor analyses were applied to examine comorbidity patterns. Result: From the dataset, there were 14 042 patients aged ≥65 with recorded chronic conditions. Of these, 2688 reported to have other comorbidities in addition to the diagnosis of diabetes. Hypertension was present in 67.33% (95% CI: 64.62 – 70.04) of these participants, followed by hyperlipidemia, 44.85% (95% CI: 41.80 –47.90), ischemic heart disease, 22.81% (95% CI: 20.74 – 24.87), atrial fibrillation, 10.25% (95% CI: 8.86 – 11.63), congestive heart failure, 7.03% (95% CI: 5.99 – 8.09), stroke/cerebrovascular accident, 6.76% (95% CI:5.36 -8.16) and peripheral vascular disease 5.26% (4.36 – 6.15). Top non-cardiovascular co-morbidities included arthritis, 51.78% (95% CI: 48.80–54.77) and depression, 15.52% (95% CI 13.78 –17.27). We identified two comorbidity patterns among older people with diabetes. The first were primarily psychological and musculoskeletal (Depression, Anxiety, Insomnia, Chronic Back Pain, Arthritis, Gastroesophageal Reflux Disease, Osteoporosis) and the second were cardiovascular conditions (Congestive Heart Failure, Ischaemic Heart Disease, Atrial Fibrillation, Peripheral Vascular Disease) and Chronic Renal Failure. Conclusion: The prevalence of cardiovascular and non-cardiovascular comorbidities in older patients with diabetes was high. These findings highlight the need for elaborating primary care strategies to reduce cardiovascular risk and improve long-term care for this population.
