Outcomes and impact

  • Improved health outcomes and reduced asthma triggers, exposure to allergens, use of urgent care, and related health care costs
  • Increased participant knowledge and awareness of environmental home-based hazards
  • Increased preventative measures against in-home hazards
  • Reduced school and work absences for asthmatic children and adults
  • Decreased health disparities, particularly when targeted at lower-income urban and rural populations

Keys to successful implementation

  • Note: This content is under review
  • Train community health workers to provide participants with mitigation strategies on environmentally-induced symptoms, including how to identify and eliminate triggers.
  • Provide community health workers conducting home visits with patient-friendly printed resources on best practices to manage home health risks, as well as information on additional health and social services available to them.
  • Encourage community health workers to use home visits not just for an inspection, but also to work with patients on developing and implementing a health risk reduction and mitigation plan.
  • Invest in enough community health workers to ensure they have the capacity for semi-regular visits (such as biweekly or monthly).
  • Recruit community health workers who can provide culturally appropriate services for the communities in which they are serving, including fluency in commonly-spoken languages.
  • Develop a clear set of referral criteria for potential program participants, including the type of home they live in, income, and community factors.
  • If funding allows, consider providing program participants with supplemental services, such as cleaning supplies, mattress covers, and mold remediation work.
