Objectives• Describe the players: the Centers for Disease Control and
Prevention, its interaction with emergency medicine, and opportunities for emergency physicians at CDC and NGOs
• Describe the need for cost-effectiveness analysis• Interpret cost-effectiveness figures in terms of QALYs and
DALYs• Describe applications of cost-effectiveness analysis to ED
and marginalized populations

CDC: Emergency Response & Recovery Branch (ERRB)• Originally the Communicable Disease Center• Now organized into Centers focused on Communicable &
Noncommunicable classes of disease• Center for Global Health at CDC covers diseases outside the
US• ERRB: Addresses needs of acutely displaced populations (refugees and
internally displaced persons)• Collaborates with WHO, UN High Commissioner for Refugees, and NGOs• Data Processor; invited in by partners

CDC: Epidemic Intelligence Service (EIS)• 2-year, post-residency training program for clinicians• Field epidemiology experience• EIS Officers are assigned to state-level positions or disease-level
positions• EM-relevant skillset: Quick decisions with limited information,
practical questions, at-risk populations [Ebola]• Challenges
• No clinical work

Fundamentals of Cost-Effectiveness Analysis

Why Should I Care About Cost-Effectiveness?• Resources are finite• Need to evaluate interventions on a common scale in order to
prioritize funding – globally or locally• Your paycheck will depend on showing the value of your work

Vocabulary• Life-Year: One year of life lived• Quality-Adjusted Life-Year (QALY): Years of life gained by an
intervention, multiplied by a quality of life multiplier (0 to 1)• Disability-Adjusted Life-Year (DALY): Years of life from an
intervention plus years of disabled life multiplied by a disability multiplier (0 to 1), weighted to favor younger age.

Example• In surveys, losing both legs has a DALY weight of 0.5 .
In other words, people think that losing your legs for 2 years is just as bad as dying 1 year earlier.
• Isn’t this ageist, ableist, and otherwise discriminatory?• YES.

QALYs vs DALYs• Very similar but not interchangeable• DALYs prioritize those interventions that save the lives
of youth more than those interventions that add a few years of life or health to an older person
• DALYs are usually favored

What determines if something is cost-effective?• It’s cost-effective if you can afford to pay for the years of life saved.• In other words: Cost per DALY saved < Your annual salary
• On a population scale: Cost per DALY saved < Country’s Gross Domestic Product per capita
• In the US, traditionally: Cost per DALY saved < $50,000

Application: Hepatitis B prevention in refugee camps• Hep B is vertically transmitted from mother to child• Administering Hep B vaccine within 24 hours of birth prevents
vertical transmission• Refugee camps have limited budget for food, water, etc• Question: Is it worthwhile to allocate $ from refugee camp budget to
pay for additional vaccination at birth, in addition to routine immunization?

Review Questions5. Jeremy called the ECMO team to save the life of a 50-year-old patient with STEMI and cardiac arrest. The patient was on ECMO for 3 days, had a completely successful cardiac cath, an additional 1-week stay in the ICU and 1-week floor stay. He is now disabled at home and gets around in a wheelchair. Is this cost-effective?
A. YesB. No
ECMO $30,000/day x 3 days + Cath $10,000 + ICU $10,000/day x 7 days + Floor $2,000/day x 7 days = $184,000
Patient may live to age 70. 20 years of life x quality adjustment of 0.5 = 10 QALYs
$184,000 / 10 = $18,400 per QALY
