Healthy home environment assessments

Healthy home environment assessments engage home visitors, often community health workers (CHWs), similarly trained asthma outreach workers, other professionals, paraprofessionals, or volunteers to assess and remediate environmental health risks within the home (ALA-MHE, Kearney 2014). Programs typically focus on improving asthma management via low cost changes such as improved ventilation, integrated pest management (IPM), and other forms of allergen control. Programs may also provide low emission vacuums, allergen-impermeable bedding covers, air filters, cleaning supplies, and supplies for roach abatement (, ).

Expected Beneficial Outcomes (Rated)

  • Reduced exposure to allergens

  • Reduced hospital utilization

  • Improved health outcomes

Other Potential Beneficial Outcomes

  • Improved asthma management

  • Improved quality of life

  • Improved indoor air quality

Evidence of Effectiveness

There is strong evidence that healthy home environment assessments encourage household behaviors that reduce asthma triggers and exposure to allergens (, , LeCann 2017, ), decrease use of urgent care and related health care costs (, , , , , Kearney 2014), and improve health outcomes (, , , , ).

Healthy home environment assessments conducted by community health workers (CHWs) or trained asthma outreach workers reduce children’s allergy and asthma symptoms, use of asthma medications, and asthma-related hospital visits (), and may also reduce the number of asthma-related doctor’s appointments (Mankikar 2016). Programs have been shown to improve asthma self-management, increase the number of asthma symptom free days (, , Kearney 2014, , ), and can reduce activity restrictions for asthmatic children (). Programs improve quality of life (, , Kearney 2014, , ) and reduce school and work absences for asthmatic children and their caregivers ().

Healthy home environment assessment programs benefit adults and children with asthma in urban and rural areas () and reduce racial and ethnic disparities in health outcomes among children with asthma (). Such programs increase the use of air filters, improve allergy and asthma symptoms, and reduce exposure to secondhand smoke (SHS) for urban, minority children from low income families (), as well as for asthmatic adults and children in lower quality housing (, ). Programs have also been shown to improve home air quality and reduce urgent care admissions for minority and disadvantaged families in rural areas (Kearney 2014, Postma 2011).

Healthy home environment assessments improve user comfort, including temperature and humidity, and may reduce the presence of molds (LeCann 2017). Programs can increase knowledge of home hazards and reduce them, including basement, roof, and plumbing leaks, particularly if program methods and materials are sensitive to low literacy levels and cultural differences among participants (Mankikar 2016).

Economic evaluations indicate healthy home environment assessments achieve high cost savings largely due to averted urgent care clinic visits, emergency room visits, and hospitalizations (, , , Kearney 2014, ). Low-intensity, healthy home environment assessment programs for people with asthma show greater cost reductions when services are targeted to those with the worst controlled asthma, including children and adults in rural and urban settings ().

Impact on Disparities

Likely to decrease disparities

Implementation Examples

Healthy home environment assessments are in place throughout the country. For example, Seattle, Washington’s King County Asthma Program, Healthy Homes, engages community health workers (CHWs) to conduct home visits focused on controlling asthma (, Seattle-Asthma program). The Master Home Environmentalist Program (MHEP) launched by Washington’s American Lung Association, trains volunteers to identify health hazards in the home (e.g. dust, lead, household chemicals, mold, and other air pollutants), use low cost methods to reduce risks, and train families to improve their home environments (ALA-MHE).

The Eastern Carolina Asthma Prevention Program’s Asthma Case Managers (ACM) provide education and resources to control asthma and allergen triggers in the home, largely to low income families with children (ECAPP, Kearney 2014). The Minnesota Department of Health’s Asthma Program offers training, resources, and mentoring for local public health agencies interested in delivering asthma home-based services, including environmental assessments (MN DOH-Asthma toolkit).

Healthy Housing Solutions’ National Healthy Homes Training Center offers in-person and online training in healthy homes assessments and interventions, including specialized courses for CHWs (Solutions-Healthy homes training). The New England Healthy Homes Training Center at the University of Massachusetts Lowell is a training partner of the National Healthy Homes Training Center which provides on-site classes (NEHHTC).
