Chapter 4: Improvements in Health Flashcards
Reasons for decreased death rates
- Better control of infectious diseases, bacteria & viruses
- Improved hygiene, sanitation and nutrition
- Advancements in medical technology
- Better understanding of dehydration
Reasons for the decline in infant deaths
- Improved access and quality of neonatal care
- Reduced preventable disease due to immunisation
- Improved sanitation and hygiene
Public health
- Organised response by society to protect and promote health, and to prevent illness, injury or disability
- Actions to improve public health in Australia include:
- Improving and protecting water quality
- Improving immunisation levels of a population
- Implementing screening programs for diseases
- Implementing anti-smoking education campaigns
NOTE: Efforts to improve public health typically target the factors that cause illness rather than treating their consequences.
Public health intelligence, programs and infrastructure
- Intelligence – info that identifies trends of ill-health and health in the population and info about the factors
- Programs – development of policy and the planning of strategies that aim to prevent, protect and promote health
- Infrastructure – implemented by the workforce and administrative, legislative, research systems
‘Old’ public health
- Focus on disease treatment and improving infrastructure, shelter, water and sanitation
- Health was seen as the absence of illness
- Helped ↓ prevalence of communicable disease (e.g. malaria)
- Does not tend to consider broader determinants of health (e.g. lifestyle choices)
NOTE: The different eras are not examinable.
Biomedical approach to health
- Focus on physical aspects of disease and illness
- Diagnosis – identification via medical tests
- Cure & treatment – interventions to control illness
- E.g. blood tests, x-rays and chemotherapy
Strengths and limitations of the BMH
-
Strengths
- Provides treatment for many conditions (↑ LE)
- Helps us learn more about disease and illness
- Can reduce the time people spend in ill health
- Advances in medical technology
-
Limitations
- Incurs ongoing expenses which can be expensive
- Not every illness or disease can be cured/treated
- Views the body in isolation to the environment
- Does not always promote equity
Improvements in medical technology
BMH
-
Medical procedures e.g. organ transplants
- Transfer of human cells, tissues or organs from a donor to a recipient with the aim of restoring bodily function(s)
- Improves physical capacity to perform daily tasks
-
Diagnostic tools and equipment e.g. MRI scans
- Produce images of internal structures of the body, enabling the accurate diagnosis of illness and disease
- Allows appropriate treatment to be implemented, reducing the time people spend in poor health
-
Medication e.g. chemotherapy
- Cancer and CVD can be effectively treated in many cases, reducing mortality rates
New public health
- Focus on disease prevention, health promotion, social support, equity, behaviour and lifestyles
- Considers all threats to health e.g. sustainability & environment
- Individuals are encouraged to take responsibility for their health
- Involves the BMH, SMH and OCHP
Social model of health
- Directs effort toward the social, economic and environmental determinants of health
- Works alongside the biomedical model
- E.g. smoking education campaigns
Key principles of the social model of health
AREAS
-
Addressing the broad determinants of health
- Considering biological, sociocultural and environmental factors and how they influence the HWB of communities (not just individuals)
- Society is able to share responsibility for health and promote health among the most vulnerable
-
Reducing social inequities
- Providing all groups with the same access to resources
-
Empowering individuals and communities
- Providing resources and knowledge to give people the opportunity to improve their HWB
-
Access to healthcare
- Everybody having access to essential healthcare services
-
(S) Inter-sectorial collaboration
- Collaboration between public and private sectors of the economy to achieve health-related goals
- By combining efforts, determinants of health are better addressed
Strengths and limitations of the SMH
-
Strengths
- Aims to improve health by preventing, not treating illness
- Focus on populations rather than individuals
- Typically more cost-effective
- Promotes equity (focus on vulnerable groups)
-
Limitations
- Hereditary conditions cannot be prevented
- Health promotion campaigns are not always be successful
- Relies on individuals making good choices
Relationship between the BMH and the SMH
-
Biomedical model
- Research a disease and effective treatment options
- Accurate diagnosis of disease via medical tests
- Provision of appropriate treatment
- Improvements in chemotherapy
- Developing stem cells that can grow new organs for transplants
-
Social model
- Promote healthy lifestyles using the media and GPs
- Providing ads in various languages and forms
- Introducing compulsory wearing of seatbelts
- Increasing taxation of tobacco/alcohol
- Banning smoking in public spaces
- Legislations to fence swimming pools
NOTE: The two models can work concurrently to achieve a common goal.
Ottowa Charter for Health Promotion
Developed by the WHO
- Attempts to reduce inequalities in health
- Developed from the social model of health
- Defines health promotion as the process of enabling people to increase control over, and to improve, their health
OCHP’s three basic strategies for health promotion
EMA
-
Enable – supporting people with the info, opportunities, resources and skills they need to make health-promoing choices
- E.g. health promotion campaigns for vulnerable groups
-
Mediate – ensuring that diff sectors all share the
responsibility of delivering health promotion for optimal health- E.g. smoking cessation campaigns being delivered by the health sector, workplaces, media, etc.
-
Advocate – promoting initiatives that improve health and protecting health as a resource using health
- E.g. delivering health campaigns that demonstrate how exercise improves all dimensions of HWB
