The 20th century witnessed the largest global increase in life expectancy in history.
Will the 21st century build on the successes of the last century, plateau, or will we see a retreat from the gains of the past?
7
Will this be the century of disease?
• HIV/AIDS• Cardiovascular disease• The persistence of high, but
preventable levels of malaria, TB, diarrhea, and pneumonia
• Avian flu/emerging infections/pandemics
Four challenges:

The Disease Control Priorities Project offers priorities for action that will lead to healthier and longer lives in developing countries.

What is the DCPP?
DCPP is an alliance of organizations/partners designed to review, generate and disseminate information on how to improve population health in developing countries.

• Fogarty International Center, US National Institutes of Health
• World Bank
• World Health Organization
• Population Reference Bureau
• Supported by the Bill & Melinda Gates Foundation
10
Objectives of DCPP (1)
Inform health sector decision-making in developing countries to decrease illness, disability, death, and economic burden by:
Developing an evidence base to inform decision-making by:
• Providing estimates of the cost-effectiveness and impact of single interventions and packages
• Collaborating in defining disease burdens globally and regionally
• Summarizing implementation experience in different regions and globally
4
11
Objectives of DCPP (2)
Communicating major findings
• Suggesting the “best buys” and the “worst buys” in any given setting
• Disseminating the results widely to multiple audiences
• Stimulating national priority setting and program implementation
5
12
The best health care solutions:
• Target major causes of death, disability and illness in developing countries;
• Are cost-effective; and• Are available.
13
How can DCPP improve health globally?
• Helps countries choose the best health care investments.
• Recommends 10 best health buys that are highly cost-effective in many settings.
• Identifies health policy priorities for developing countries.
• Suggests changes to infrastructure (health systems, financing, policies, R&D) to maximize results.
14
Burden of Disease (BOD)
BOD analysis provides a standardized framework for integrating all available information on mortality, causes of death, individual health status, and condition-specific epidemiology to provide an overview of the levels of population health and the causes of loss of health
Consistent, comprehensive descriptive epidemiology Common metric or summary measure (e.g. DALY), that allows for comparisons across diseases and interventions
15
The DALY:
• Combines years of life lost to premature mortality and years spent with a disability or illness
• Provides a metric of disease impact (“burden of disease”) reflecting both mortality and morbidity
• For example, diabetes in high income countries comprises 2.1% of deaths and 2.8% of DALYs

BOD and Comparative Risk Assessment (CRA)
• BOD reflects impact of illness and disability
• Risk factors tell us the causes behind disease and disability
• Comparative risk assessment shows potential gains in population health from reducing the risk exposures

messages

Objective: Improve Quality of Health Spending
• Provide information on the “price” of buying health through different interventions
• Policymakers can combine this information with other considerations to determine how best to improve health

22
Interventions Covered
• Cost effectiveness of 257 interventions in $/DALY averted (DCP1 had 68)
• Cost effectiveness of an additional 62 interventions using other metrics (26 in DCP1)
• Also provide information on• Cost-effectiveness by region• Target population• Personal versus population• Avertable burden• Quality of evidence
23
Reduce Fatal and Disabling Injuries
Injuries and violence caused more than 5 million deaths in 2001, with an especially
heavy toll on young men.
• Install speed bumps at dangerous intersections.
• Increase penalties for speeding; awareness through media; and law enforcement.

Stop the Spread of Tuberculosis
Tuberculosis (TB) is spreading into new populations and resisting treatment
• Treat active TB cases with short-course chemotherapy.
• Increase case detection.• Manage multidrug resistant TB with
new drugs and drug combinations.

Control Malaria
Malaria claims the lives of 1 million children yearly, and it threatens nearly one-half of the world’s population.
• Provide universal access to insecticide-treated nets in areas where malaria is endemic.
• Expand intermittent preventive treatment for pregnant women.
• Subsidize artemisinin combination therapy to ensure effective treatment.

Ensure Healthier Children
More than 13 million children (including stillbirths) die each year in developing countries.
• Keep newborns dry, warm and clean.• Vaccinate children against major childhood
killers.• Monitor children’s health to prevent and treat
childhood pneumonia, diarrhea, and malaria.

Combat Tobacco Use
Tobacco-related diseases are the fastest-growing cause of disease and disability in developing countries.
• Tax tobacco products to increase consumers’ costs by at least 33% to curb smoking.
• Restrict smoking in public places and workplaces.
• Provide nicotine replacement therapy and other cessation tools.
• Ban tobacco advertising.
36
Most smokers now live in low- and middle-income countries.

• Bypass surgery for less severe Very small (Very high) coronary artery disease
39
To get the best results:
• Choose interventions with low cost and high impact
• Strengthen health systems• Engage global partners and donors• Accelerate research and
development
