Study Notes
Measuring Health
- Gapminder.org: A platform showcasing data visualizations for understanding global health trends.
- Hans Rosling: Founder of Gapminder, a strong proponent of using data visualization for better global understanding.
- Association between wealth and health: There is a strong association between wealth and health.
- Data Visualization: This is an effective method to understand the world.
-
Key global health metrics:
- Life expectancy at birth
- Child mortality (death rates)
- Maternal mortality (death rates)
- Central Statistics Office, Cork: This is a primary source for national data in Ireland.
- Health Protection Surveillance Service: This organization monitors health issues at a national level.
Global Burden of Disease (GBD)
- Measures health, disease, mortality, morbidity, and health outcomes.
- DALY (Disability-Adjusted Life Year): A measure of overall disease burden, encompassing both mortality and morbidity.
- Institute for Health Metrics and Evaluation (IHME): This organization compiles and analyzes GBD data.
Measuring Death
-
Uses of mortality data:
- Allocation of scarce resources
- Cross-country comparisons
- Disease analysis
- Tracking health over time
- Death certificates: Primary source for mortality data.
- Limitations of mortality data: Most accurate in well-organized health systems and may not capture all deaths.
Measuring Illness and Disability
- Quality of life questions: Used to gather information on individuals' perceived well-being.
- Activity of daily living (ADL): Assessing an individual's ability to perform basic tasks.
- Age at death: A factor in life expectancy calculations.
- Life expectancy: Average lifespan of a population.
- Happiness: A subjective measure of well-being.
Using Data to Compare Health Across Countries
- Examples of comparisons: Road accidents, diabetes, low back pain, drug use, comparing countries like Ireland, Bahrain, Malaysia, Sierra Leone, and the USA.
Predicting Future Health Burdens
- Factors influencing future health burdens: Conflict, climate change, and improved access to sanitation.
Case Study: Severe COVID-19
- Presenting Symptoms: Cough, shortness of breath, fever, tiredness, and inability to get out of bed.
-
Relevant Data:
- Patient's age: 45 years old
- Patient's weight: 140 kg
- Peripheral oxygen saturation: 85% (low)
- Arterial blood gases indicated Type 1 respiratory failure.
-
Treatment Escalation:
- Nasal oxygen
- Continuous Positive Airway Pressure (CPAP)
- Mechanical ventilation (intubation)
Measuring Health
- Global Burden of Disease (GBD) uses lost years of life due to early death and partial years of life lost due to disability and morbidity as measures
GBD - Health Measurement
- Mortality is measured by death certificates.
- Morbidity and Disability are measured by self-reported quality of life questionnaires, ability to do activities of daily living, and age at death.
GBD - Strengths and Weaknesses
-
Strengths:
- Useful for allocating scarce resources
- Enables comparison across countries, diseases, groups of people, and over time.
- Useful for understanding health and disease associations with wealth and education.
- Helps measure social and economic impact of health and disease.
-
Weaknesses:
- Recollection bias
- Restricted to regions with organised health systems.
Key Data Sources
- Gapminder.org: Multidimensional visual display of data for understanding the world.
- Our World in Data: Provides data on life expectancy at birth, child mortality, and maternal mortality ratio.
- Central Statistics Office (Ireland): National agency providing Irish health data.
- Health Protection Surveillance Service (Ireland): National agency providing health data.
- Euromomo: Measures all deaths in Europe
Global Burden of Disease (GBD) Study Data
- The Lancet: Has published studies on GBD.
- Institute for Health Metrics and Evaluation: Provides data and resources related to GBD, including a link to their website.
Clinical Features of Severe Covid-19
- A 45-year-old man, weighing 140kg, presented with cough, shortness of breath, fever, tiredness, and inability to get out of bed in March 2020.
- Peripheral oxygen saturation on room air was 85%.
- Nasal oxygen was administered.
- Arterial blood gases showed Type 1 respiratory failure.
- Oxygen therapy was escalated.
- Continuous Positive Airway Pressure (CPAP) was used.
- Mechanical ventilation was required via intubation.
Measuring Health
-
Measuring health outcomes is crucial for resource allocation, comparing across countries, understanding health and disease trends, and assessing the social and economic impacts of health.
-
Methods of measuring health:
- Life Expectancy at Birth: The average number of years a newborn is expected to live.
- Child Mortality: Measured as deaths of children under 5 years old per 1000 live births.
- Maternal Mortality Ratio: The number of maternal deaths per 100,000 live births.
- Quality of Life: Measured using questionnaires to assess an individual's perceived quality of life.
-
Data Sources:
- Gapminder.org: A website that uses visual displays of data to help understand the world.
- Our World in Data: A collaborative project that provides free access to high-quality data on various topics, including health.
- Euromomo: A European mortality monitoring system providing data on all deaths.
Global Burden of Disease
-
Global Burden of Disease (GBD) Study: A comprehensive research effort to assess global health, disease, mortality, and morbidity.
-
DALY: Disability-Adjusted Life Year, a metric used in the GBD study that measures the total years lost due to premature death and years lived with disability.
-
Disability: Measured using partial years of life lost, reflecting the impact of disability on quality of life.
Comparing Disease Burden Across Countries
- Examples of diseases to compare: Road accidents, diabetes, low back pain, and drug use.
- Countries to compare: Ireland, Bahrain, Malaysia, Sierra Leone, and the USA.
The Future of Global Health
-
Factors shaping the global burden of disease over the next century:
- Conflict and instability
- Climate change
- Improved access to sanitation
COVID-19 Case Study
-
A 45-year-old male with a BMI of 40 presented to a hospital in March 2020 with symptoms of COVID-19. These symptoms included cough, shortness of breath, fever, tiredness, and inability to get out of bed.
-
Clinical features of severe COVID-19:
- Oxygen saturation of 85% on room air
- Type 1 respiratory failure
-
Management of severe COVID-19:
- Oxygen therapy
- Continuous Positive Airway Pressure (CPAP)
- Mechanical ventilation
