Measuring The Impact Of Air Pollution On Health Care Costs

Area of Science:

• Environmental health science
• Health economics
• Public health policy

Background:

• Air pollution is a significant contributor to adverse human health outcomes.
• The Environmental Protection Agency's BenMAP-CE tool is crucial for estimating air pollution's health care costs and informing policy.
• Current BenMAP-CE estimations primarily include hospital and emergency department costs, omitting other essential care categories.

Purpose of the Study:

• To incorporate ambulatory and other care costs into air pollution health care cost estimations.
• To provide a more comprehensive accounting of the economic burden of air pollution-related illnesses.
• To re-evaluate the estimated health care benefits of air pollution reduction strategies.

Main Methods:

• Utilized employer health insurance claims data to identify costs beyond hospitalizations.
• Inferred additional health care expenditures associated with respiratory and cardiovascular conditions.
• Compared these comprehensive cost estimates with existing BenMAP-CE default values.

Main Results:

• Including ambulatory and other care costs increased BenMAP-CE estimates by approximately 40% for respiratory and cardiovascular patients.
• This suggests a significant underestimation of total health care costs associated with air pollution.
• For every dollar captured by BenMAP-CE, an additional 40 cents in health care costs were identified.

Conclusions:

• Existing air pollution health care cost estimates are likely underestimated.
• The health care benefits of air pollution mitigation may be substantially larger than previously calculated.
• Policy decisions and regulations should consider these broader economic impacts for more effective public health interventions.
