Economic Evaluation / Methods and Source

Type:

• Cost-benefit analysis (CBA), Cost-effectiveness analysis (CEA)

Cost Measures:

• Reviewed publications that examined program costs (costs of resources required to implement intervention) which varied based on the following factors — home visitor type (e.g., nurse, sanitarian), number of home visits, remediation type (e.g., allergen impermeable pillow covers/mattresses, installation of air filters/dehumidifiers, pest management, repairs), and education content

Potential Cost Measures:

• Not available

Benefits Measures:

• Reviewed publications that examined benefits such as — symptom free asthma days
• averted healthcare utilization
• averted missed school and work days due to illness
• averted productivity losses

Potential Benefits Measures:

• Reduction of indirect costs such as costs related to quality of life and pain/suffering for asthma patients and caregivers

Location:

• Eleven studies in the United States
• two studies in the United Kingdom

Models Used:

• Not available

Models References:

• Not available

Methods Used:

• The authors systematically assessed the economic efficiency of home-based, multi-trigger, multi-component interventions with an environmental focus to improve asthma-related morbidity outcomes. The authors — 1) conducted a systematic literature review to retrieve relevant studies; 2) vetted the results using inclusion/exclusion criteria; and 3) analyzed program costs and changes in symptom free days.
