Estimating the Cost of Pediatric Asthma Attributable to the Environment Michigan, 2013
SLIDE 6 Background
- Previous studies
- Landrigan, 2002
- States, 2003-present
- Trasande, 2012
SLIDE 7 Components of ‘Cost’
- Direct costs
- Medical (inpt, outpt, ED, dr visits, Rx med)
- Indirect costs
- Premature death
- Parents’ lost workdays
SLIDE 8 Key Concepts
- Medical Expenditure Panel Survey
- Incremental Cost
- Environmentally Attributable Fraction
SLIDE 9 Methods
- Environmentally Attributable Fraction (EAF)
- Pediatric Asthma
- Acute exacerbations
- Outdoor pollutants (e.g., excludes pets, tobacco smoke, mold, insects)
- Best estimate: 30%
- Lower bound: 10%
- Upper bound: 35%
SLIDE 10 Methods
- Adjusting for inflation
- Consumer Price Index
- Overall
- Medical Care
SLIDE 11 Methods
- CDC’s Chronic Disease Cost Calculator
- Calculates
- Direct costs
- Indirect costs for missed workdays only
- Costs based on Medical Expenditure Panel Survey (MEPS)
SLIDE 12 Methods
- Target year: 2013
- Triangulation
- Method 1
- Use CDC’s Chronic Disease Cost Calculator
- Adjust for inflation
- Calculate costs for premature deaths separately
- Method 2
- 2008 U.S. results
- Adjust to 2013 dollars
- Apply to MI population

SLIDE 34 Assumptions
- 1. MI = US for direct & indirect costs per person
- 2. Medical Care CPI accurate for asthma
- 3. EAF of 30% applicable to MI
SLIDE 35 Discussion
- Direct costs very similar ($50.1 v. $48.9)
- Cost calculator easy to use
- Difference in indirect costs – Method 1 v. Method 2
- Other MI study (2010): $88.4 million
- Direct + Indirect
SLIDE 36 Discussion
- For full impact of environment on medical care costs
- Use all ages
- Look at other health conditions (e.g., cancer, lead poisoning)
SLIDE 37 Next Steps
- Develop paper
- Develop fact sheet
