Measuring & Interpreting Health Status
Explain why life expectancy alone does not provide a complete picture of a population’s health.Explain why life expectancy alone does not provide a complete picture of a population’s health.
Life expectancy does not show quality of life, disability-free years, prevalence of chronic disease, or inequities within subgroups.
Why do ATSI Australians experience lower life expectancy?
Due to determinants such as lower SES, geographic isolation, intergenerational trauma, and limited access to culturally safe care.
How does Medicare improve equity?
Provides free/subsidised GP and hospital care, reducing financial barriers.
How do wearable technologies improve outcomes?
Monitor real-time data (e.g., glucose, heart rate) → early detection and self-management.
Two reasons for Australia’s ageing population?
Increased life expectancy and declining birth rates.
Differentiate between morbidity and mortality using a named chronic disease.
Morbidity refers to the prevalence/incidence of disease (e.g., number living with CVD), while mortality refers to deaths caused by that disease.
How does geographic isolation affect health outcomes?
Reduced access to specialists, higher costs, fewer services → delayed treatment and higher mortality.
Compare public and private hospitals.
Public: Medicare funded, accessible. Private: faster access, more choice, requires insurance/payment.
How does telehealth improve and limit equity?
Improves rural access but limited by digital literacy and internet availability.
How does ageing increase healthcare pressure?
Higher chronic disease prevalence, increased hospitalisations, aged care demand.
Australia’s infant mortality rate is ~3 per 1,000 live births. What does this indicate?
It indicates strong maternal/child healthcare, good hospital access, and effective public health systems.
How does socioeconomic disadvantage increase chronic disease risk?
Lower income limits access to healthy food, education, health services → higher smoking, obesity, inactivity.
Why is healthcare high quality but not fully equitable?
Strong services overall, but inequities persist in ATSI, RAR and low SES populations.
How do Electronic Health Records improve efficiency?
Reduce duplicate tests, improve communication, centralise patient data.
How does healthy ageing reduce costs?
Prevents chronic disease, reduces hospital admissions, promotes independence.
How does epidemiological data identify priority groups?
By identifying patterns in prevalence, incidence, mortality and burden of disease across subgroups (e.g., ATSI, RAR).
How does colonisation continue to impact ATSI health?
Intergenerational trauma, loss of land/culture, discrimination → poorer mental and physical health outcomes.
Implications of rising healthcare expenditure?
Challenges sustainability due to ageing population, technology costs, chronic disease rates.
How does big data inform policy?
Identifies disease trends, guides funding allocation, supports prevention programs.
How is SDG 3 linked to SDG 4 or 10?
Health is improved through education (SDG 4) and reducing inequalities (SDG 10).
Evaluate strengths and limitations of epidemiology
Strengths: identifies trends, supports policy decisions. Limitations: does not explain causes, lacks qualitative context.
Assess effectiveness of Close the Gap.
Has improved some education and health targets, but life expectancy gap and chronic disease inequities remain.
Should prevention receive greater funding? why
Yes – prevention reduces long-term chronic disease costs and healthcare burden.
Do benefits of digital health outweigh privacy risks?
Generally yes for improved care and efficiency, but strong cybersecurity and regulation are essential.
Is Australia prepared for ageing demands?
Partially prepared – strong system, but workforce shortages and rising costs remain challenges.
