Trends associated with a number of risk factors for chronic conditions among the Australian population continue to put a large number of people at risk of developing chronic conditions: among people aged 18 and over levels of inadequate physical inactivity and fruit or vegetable consumption have remained high since 2007–08, while levels of overweight and obesity have increased (ABS 2018). If left unchecked, trends in chronic condition risk factors, combined with a growing and ageing population and better treatment and management of chronic conditions, will lead to increasing numbers of people living with multiple chronic conditions.
In contrast, smoking rates have consistently declined in Australia over the past two decades, with 11% of Australians aged 14 and over smoking daily in 2019 compared with 24% in 1991 (AIHW 2020). Helping people to make good lifestyle choices and actively self-manage existing chronic conditions, including by accessing available treatments and services and adhering to long-term therapies, can help to keep people in good health and prevent illness. Having an accessible and integrated health care system is also important.
Most care for chronic conditions is provided in the primary health care setting by general practitioners (GPs) and allied health practitioners, with the number of GP visits increasing with increasing number of chronic conditions (Dobson et al. 2020). Mental and behavioural conditions (including anxiety, depression and mood disorders), musculoskeletal (including arthritis), respiratory (including asthma) and endocrine and metabolic conditions (including diabetes) were the most common health concerns managed by GPs in 2019 (RACGP 2019). Effective primary health care can help prevent unnecessary hospitalisations and improve health outcomes (AMA 2017; OECD 2017).
Multiple medications and therapies are often needed to manage multiple conditions, which requires extra attention from clinicians to reduce the risk of overprescribing and treatment conflicts such as dangerous drug interactions (AIHW 2014; Harrison & Siriwardena 2018; Starfield 2006). For example, the presence of coronary heart disease in people with COPD requires more careful management of certain medications such as beta-blockers (Albouaini et al. 2007). And, detailed clinical guidelines advise clinicians on the treatment of asthma when co-existing with COPD, due to the impact of treatment on the individual conditions (National Asthma Council of Australia 2019). More detailed information on the treatment and management of specific chronic conditions can be found on the Chronic disease web pages.
People with chronic conditions can also be more vulnerable to the effects of certain communicable diseases, including Influenza and Coronavirus disease (COVID-19). While most people will only experience relatively mild/moderate symptoms after contracting these diseases, people with chronic conditions including cardiovascular disease, diabetes, chronic respiratory disease and cancer can develop more serious illness (NSW Health 2018; WHO 2020). Vaccination against Influenza (having a ‘flu’ shot) is strongly recommended each year for people with these conditions to reduce the risk associated with contracting Influenza (NSW Health 2018). Likewise, vaccination against COVID-19 is recommended for all Australians but those with an underlying medical condition, including a disability, have been prioritised in Australia’s COVID-19 Vaccine and Treatment Strategy (Department of Health, 2021). To reduce the risk of transmitting or contracting Influenza or COVID-19, hand washing/sanitising, practising appropriate cough/sneeze etiquette, physical distancing and self-isolating (if necessary) is recommended (Department of Health 2020a; NSW Health 2018; WHO 2020).
Within Australia, it is recognised that multimorbidity increases the complexity of patient care (Harrison & Siriwardena 2018), yet it is accepted that, historically, there has been a lack of coordination and communication between different parts of the Australian health care system (Department of Health 2020b).
The Australian Government has implemented a number of approaches with the aim of improving coordination and care for people with chronic conditions, including:
In 2017, all Australian health ministers endorsed the National Strategic Framework for Chronic Conditions (the Framework; AHMAC 2017). The Framework provides guidance for the development and implementation of policies, strategies, actions and services to tackle chronic conditions. It moves away from a disease-specific approach and better caters for shared health determinants, risk factors and multimorbidities across a broad range of chronic conditions.
The Framework outlines 3 objectives that focus on: preventing chronic conditions, and thus minimising multimorbidities; providing efficient, effective and appropriate care to manage them; and targeting priority populations (AHMAC 2017). The Framework will be complemented by the development of a 10-year National Preventive Health Strategy announced by the Minister for Health in June 2019 (Department of Health 2020c).
