Estimating the Cost of Pediatric Asthma Attributable to the Environment Michigan, 2013

Background • Previous studies • Landrigan, 2002 • States, 2003-present • Trasande, 2012

Components of ‘Cost’ • Direct costs • Medical (inpt, outpt, ED, dr visits, R x med) • Indirect costs • Premature death • Parents’ lost workdays

Key Concepts • M edical E xpenditure P anel S urvey • Incremental Cost • E nvironmentally A ttributable F raction

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%

Methods • Adjusting for inflation • Consumer Price Index • Overall • Medical Care

Methods • CDC’s Chronic Disease Cost Calculator • Calculates • Direct costs • Indirect costs for missed workdays only • Costs based on Medical Expenditure Panel Survey (MEPS)

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

Assumptions 1. MI = US for direct & indirect costs per person 2. Medical Care CPI accurate for asthma 3. EAF of 30% applicable to MI

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

Discussion • For full impact of environment on medical care costs • Use all ages • Look at other health conditions (e.g., cancer, lead poisoning)

Next Steps • Develop paper • Develop fact sheet
