Asthma symptoms can lead to less time in school and more trips to the doctor. While there isn't a cure, the right environment can minimize symptoms, prevent flare-ups, and greatly improve quality of life.

Reduces exposure to multiple indoor asthma triggers (allergens and irritants) through use of home visits by trained personnel to conduct two or more activities with an environmental focus. Activities can include education, assessment and remediation.

We modeled this program for low-income (less than 200% of the Federal Poverty Level) families with at least one child, age 0 to 17, who has been diagnosed with asthma.

There are approximately 40,000 low-income children with asthma in Philadelphia.

For a $81.2 million investment covering 39,672 low-income children with asthma ($2,046 per child) the following results could be expected.

We use a variety of data sources to tailor our analysis to the location and to make our estimates as accurate as possible. However, sometimes data is unavailable, either because it has not been collected, or because it is not shared publicly. We encourage government agencies and other organizations to share their de-identified data online and researchers to prioritize the following gaps in the data. 

Asthma rates: Baseline data for asthma rates among children by planning district was available, however we were unable to collect these rates for the low income population in Philadelphia. We estimated that rates for the low-income population in a planning district were 1.5 times higher than the general population.

Low-Income Children per Household: We developed a cost scaling methodology to adjust for instances where multiple children receiving benefits from a single home remediation. One factor we took into account is the average number of children in a low-income household, however we ended up using a national number since local data was unavailable.

Distribution of Outcomes by Age: Severe asthma are more prevalent among younger children. To account for this, we gathered information from a few studies that have examined these outcomes in the past, but ideally there would have been local baseline data available.
