The Value of Asthma Home Visits
Home visits create the opportunity to provide care while also educating and supporting people with asthma to better manage their disease. Evidence shows that in-home asthma education combined with environmental trigger remediation can significantly improve health outcomes and the costs of asthma care.
When pursuing financing for in-home asthma care, it is important to let funders, partners and stakeholders know about the proven value of asthma home visits as well as your program's specific value proposition.
Evidence of the Cost/Benefits of In-Home Care & Program Models
In-Home Asthma Intervention Improves Asthma Control, Quality of Life in Adults
Dr. James Krieger, The HomeBASE Trial Randomized Clinical Trial. JAMA Intern Med, 2015;175(1):109-117.
From 2008 – 2001, in order to test the hypothesis that community health worker (CHW) home visits for adults with uncontrolled asthma improve outcomes relative to usual care, this study randomized parallel group study with 1-year follow-up at homes of low-income adults aged 18 to 65 years with uncontrolled asthma living in King County, Washington. CHWs provided a mean of 4.9 home visits during a 1-year period to assess asthma control, self-management, and home environment and to support asthma self-management practices.
Of 463 individuals who completed eligibility screening, 443 were eligible, 366 participated (177 in intervention and 189 in control groups), and 333 completed the study (91%). The intervention group had significantly greater increases in mean symptom-free days per 2 weeks (2.02 [95% CI, 0.94-3.09]; P < .001) and quality of life (0.50 [95% CI, 0.28-0.71] points; P < .001) relative to the control group, adjusted for age, sex, race/ethnicity, and education level. The number needed to treat to increase symptom-free days by 2 days per 2 weeks was 7.4 and to improve quality of life by 0.5 points was 2.6. Mean urgent health care use episodes in the past 12 months decreased significantly and similarly in both groups, from a mean of 3.46 to 1.99 episodes in the intervention group (mean change, −1.47 [95% CI, −2.28 to −0.67]; P < .001) and from a mean of 3.30 to 1.96 episodes in the control group (mean change, −1.34 [95% CI, −2.00 to −0.72]; P < .001) (P = .83 comparing groups).
Conclusions and Relevance: The provision of in-home asthma self-management support by CHWs to low-income adults with uncontrolled asthma improves asthma control and quality of life but not unscheduled health care use. Additional studies are needed to confirm these findings and determine the value of wider implementation of this approach.
