    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.

    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.
