The Houston Home-Based Integrated Intervention Targeting Better Asthma Control (HIITBAC) for African Americans
The purpose of this study is to improve the health of African-American adults who have poorly
controlled asthma. The study compares a home-based exposure reduction and asthma control
intervention to enhanced in-clinic care that includes a standard clinical appointment as well
as information from a detailed exposure history, asthma education, assessment for allergies,
and a customized asthma self-management plan developed using motivational interviewing. The
interventional group receives enhanced in-clinic care, as well as a customized home-based
environmental exposure assessment and multicomponent exposure reduction and asthma control
intervention (five home visits over approximately 12 months).

interventional group receives enhanced in-clinic care, as well as a customized home-based
environmental exposure assessment and multicomponent exposure reduction and asthma control
intervention (five home visits over approximately 12 months).
The study hypothesis is that the addition of a holistic, home-based environmental exposure
reduction and asthma control intervention to enhanced in-clinic care will result in
statistically significant improvements in key measures of health and quality of life among
Houston-area African-American adults with poorly controlled asthma.
This is a pragmatic randomized controlled clinical trial that compares the effectiveness of a
customized, holistic, patient-centered, home-based environmental intervention for improving
asthma control (the "intervention") with enhanced clinic-based care. Both arms receive
identical in-clinic care, including collected self-report information from detailed health
and exposure questionnaires, asthma education, assessment for allergies, and a customized
asthma self-management plan developed using motivational interviewing. The intent of the
study is to assess-real-life effectiveness of a home-based intervention in African-American
adults with poorly controlled asthma.

INCLUSION CRITERIA:
- African-American
- 18 years of age or older
- Diagnosis of poorly controlled asthma*
- Fixed address within Harris County, Texas, with no intention of moving within the
following 12 months
- Working telephone number
- Verbally fluent in English
- Poorly controlled asthma was defined as (1) diagnosed by a physician as having
asthma in the past and currently has asthma, and (2) fulfills one or more of the
following criteria: (a) one or more emergency department (ED), urgent care visits
or hospitalizations for asthma in the preceding year; (b) meets the definition of
"very poorly controlled" asthma as defined by the National Asthma Education and
Prevention Program, Third Expert Panel on the Diagnosis and Management of Asthma
(definition includes daily asthma symptoms, nighttime awakenings two or more
times per week, extremely limited normal activity, and/or daily use of a
short-acting beta agonist for symptom control); and/or (c) an Asthma Control Test
score of 19 or lower.
EXCLUSION CRITERIA:
- Severe co-morbid conditions—such as a poorly controlled psychiatric illness or a
condition requiring intense medical treatment that could reasonably be expected to (1)
confound the effects of this study's intervention, (2) make it unlikely that a
participant could follow the treatment plan, or (3) pose a safety issue for the
home-visit team.
- A concurrent pulmonary study that could reasonably be expected to confound the effects
of the intervention.
- Living in a group living facility, such as a nursing home.
