Summary
This cost-analysis estimated full economic costs attributable to dampness and mold from indoor air in homes in the US using available cost of illness (COI) and willingness to pay (WTP) methods. The authors designed the cost estimates to be more inclusive of costs that might be excluded or undervalued with tradition COI estimates. The authors calculated that 15–20% of asthma, acute bronchitis, and allergic rhinitis costs can be attributed to an indoor dampness and mold prevalence of 35%. The authors estimated total annual costs to society attributable to dampness and mold to be $3.7 billion for allergic rhinitis, $1.9 billion for acute bronchitis, $15.1 billion for asthma morbidity, and $1.7 billion for asthma mortality.

Methods Used:

  • The authors estimated the economic costs of allergic rhinitis, acute bronchitis, and asthma from indoor dampness and mold exposures. The authors: — 1) reviewed published meta-analyses to define the odds ratios for risk of disease, disease prevalence rates, and attributable fraction for each of the three health outcomes as related to dampness and mold exposures; 2) reviewed published studies that reported cost of illness (COI) and willingness to pay (WTP) values for the health outcomes studied, and discussed details including assumptions regarding numerous cost values obtained from those studies; 3) used estimates from those studies to calculate base case COI estimates and WTP estimates when available for each health outcome for patients and for family and friends; and 4) performed limited sensitivity analysis of alternative methods and assumptions to calculate a potential range of cost estimates.
