Home Visits Can Improve Asthma Control for Low-Income Adults

TUESDAY, Nov. 25, 2014 (HealthDay News) -- For low-income adults with uncontrolled asthma, home visitation by community health workers is associated with improvements in asthma control and quality of life, according to a study published online Nov. 24 in JAMA Internal Medicine.

James Krieger, M.D., M.P.H., from the Public Health-Seattle and King County, and colleagues conducted a parallel group study with one-year follow-up at homes of low-income adults (aged 18 to 65 years) with uncontrolled asthma. Participants were randomized to the intervention (mean of 4.9 home visits by community health workers during a one-year period; 177 participants) and control groups (usual care; 189 participants).

The researchers observed significantly greater increases in mean symptom-free days per two weeks and in quality of life in the intervention versus control group (both P < 0.001), after adjustment for age, sex, race/ethnicity, and education level. To increase symptom-free days by two days per two weeks and improve quality of life by 0.5 points, the number needed to treat was 7.4 and 2.6, respectively. There were significant and similar decreases in both groups in the mean urgent health care use episodes in the past 12 months (mean change: −1.47 in the intervention group and −1.34 in the control group; P = 0.83)

"Additional studies are needed to confirm these findings and determine the value of wider implementation of this approach," the authors write.
