Global Trends Globalization: –Increased migration and travel –Increased rapid communication –Convergence of: Markets; Technology; Policy Population: –Exponential growth –Population aging –Some declines in life expectancy –Urbanization

Global Trends Epidemiologic Transition: Shift from population dynamic of high fertility and high mortality primarily from infectious disease to lower fertility and lower mortality, primarily from chronic disease and injury/violence Different countries experience transition in different ways

Serious Challenges Escalating costs of health care Health system infrastructure Health system financing Health services workforce shortages Leadership

Serious Challenges Social disparities in health status Social disparities in access to services Political threats to health Environmental threats to health Food security threats to health HIV/AIDS Pandemic influenza

Public Health Innovations— Focus on Prevention Primary Prevention –Prevention of incidence of disease or injury –Examples: Immunizations; smoking prevention Secondary Prevention –Identify or control disease processes in their early stages, before signs/symptoms are apparent –Examples: Mammography screening; smoking cessation

Public Health Innovations— Focus on Prevention Tertiary Prevention –Prevent disability by restoration to optimal level of functioning or prevent further progression of disease –Examples: Rehabilitation after stroke; diabetes management; antiretroviral therapy for HIV

Public Health Innovations Tobacco Control –Primary prevention –Secondary prevention HPV Vaccination

Public Health Innovations Chronic Disease Management –Diabetes –Asthma Economic Incentives: –Pay for Performance (Providers) –Value-Based Insurance Design –Incentives for Patients: Positive Negative

Public Health Innovations Focus on essential medicines Barriers to existing medicines –Inadequate national commitment –Inadequate human resources –Inadequate finance from international community –Lack of coordination of aid –TRIPS agreement –Disincentives for R & D
