Estimating the "avoidable" burden of disease by Disability Adjusted Life Years (DALYs)

Area of Science:

• Public Health
• Epidemiology
• Health Economics

Background:

• The World Bank's Global Burden of Disease Study introduced Disability Adjusted Life Years (DALYs) as a key metric.
• Understanding disease burden is crucial for effective public health interventions and resource allocation.

Purpose of the Study:

• To distinguish between the total and "avoidable" disease burden.
• To clarify the appropriate use of incidence-based versus prevalence-based DALYs.
• To apply these DALY measurement methods to specific health issues in a defined region.

Main Methods:

• Differentiating between total and avoidable disease burden.
• Defining and explaining incidence-based DALYs for disease prevention.
• Defining and explaining prevalence-based DALYs for disease treatment.
• Applying these DALY estimation methods to seven causes of death and disability.

Main Results:

• Established clear criteria for using incidence-based DALYs when prevention is possible.
• Established clear criteria for using prevalence-based DALYs when treatment is the primary intervention.
• Demonstrated the application of these methods to analyze health burdens in the South and West Region.

Conclusions:

• The distinction between total and avoidable disease burden, using appropriate DALY measures, is vital for health monitoring.
• This framework aids in making informed decisions about resource allocation to improve population health.
• The study provides a practical approach for regional health authorities to assess and manage disease burdens.
