OBJECTIVES: This study applied a robust Machine Learning method to estimate the current economic burden of asthma at the state level by age group, sex, race and ethnic origin, and payer type.
METHODS: This analysis utilized data from the Medical Expenditure Panel Survey (2016-2021), U.S. Census Bureau projections, National Survey of Children’s Health (2021-2022), Behavioral Risk Factor Surveillance System (2018-2022), and Current Population Survey (2022). A two-part Random Forest model was used to estimate annual asthma-related medical costs. Costs were inflation-adjusted to 2021 USD using the U.S. Bureau of Economic Analysis’ Personal Consumption Expenditures Price Index. The study allowed us to compare per-patient costs, state totals, national estimates, and future projected costs at state and national levels.
RESULTS: Annual cost per patient for asthma-related medical costs ranged from $3,789 (Georgia) to $6,018 (Massachusetts for adults (18 years of age or older), medical costs ranged from $3,3324 (Maine) to $1,972 (Georgia) for children (17 years of age or younger). For the population of Hispanic origin, per patient asthma-related medical costs ranged from $3,980 (Louisiana) to $4,866 (Pennsylvania), which was lower compared to the range in the same states for non-Hispanic Blacks ($4,582 - $5,588) and non-Hispanic Whites ($5,053-$6,163). Missed workdays per patient for adults ranged from $284 (Alabama) to $550 (Massachusetts) and missed school days for children ranged from $98 (Ohio) to $102 (South Dakota). The annual per patient asthma-related medical costs are projected to grow from $5,168 in 2023 to $6,485 in 2035.
CONCLUSIONS: Asthma-related medical costs and indirect productivity costs exhibit strong geographic variation. Furthermore, per patient annual costs are lower for Hispanics compared to non-Hispanic Blacks and non-Hispanic Whites. These findings highlight opportunities for interventions targeting improved asthma control to reduce the economic burden of asthma.
