Characteristics of asthma programs with positive health outcomes.

  1. 1. 2634 Characteristics of Asthma Programs with Positive Health Outcomes Friedman AR MPH; Lachance L PhD; Stoll S MPH; Awad D MA; Clark N PhD Center For Managing Chronic Disease, University of Michigan School of Public Health Rationale: To better understand successful asthma programs, the Asthma Health Outcomes Project (AHOP) identified national and international asthma programs (n=500). Programs that included an environmental component and reported a positive impact on asthma-related health outcomes (n=223) were examined to identify factors associated with success. Methods: Through telephone interviews, program documents and published literature, data were gathered on program background, design, and administration, and evaluation design and findings. Descriptive frequencies provided an overall picture of work in the field, and bivariate relationships between programmatic factors and health outcomes were analyzed using X2 statistics and Fisher's exact tests (p<0.05), and unconditional logistic regression. Results: Descriptive data present a snapshot of the current field of asthma programs. For example, strategies most commonly used by surveyed programs included asthma education (96%), home visits (43%), systems change (42%), and clinical quality improvement (37%). Initial findings from bivariate analyses of 111 programs that had evaluation results reported in peer-reviewed publications were grouped into programmatic categories. These findings suggest that programs are more likely to report a positive impact on health outcomes if they: Work with health care providers; Have close ties to communities; Collaborate with others; Follow established steps of program development in order to meet the needs of the community; and are tailored to meet the needs of individual participants, particularly with regard to environmental trigger sensitivity . Conclusions: Preliminary analyses suggest that particular program processes are associated with improving health outcomes. Key descriptors of successful programs are: community centered, clinically connected, and continuously collaborative . Descriptive frequencies were drawn from the 223 surveyed programs that met the inclusion criteria: (1) focused on asthma; (2) included an environmental component (e.g., education about triggers, policy action to reduce trigger exposure); (3) completed an evaluation that showed a positive impact on at least one health outcome. Initial analyses found significant variation in program evaluations. A focused analysis was conducted on programs that reported using randomized controlled trials with evaluation results reported in peer-reviewed publications (n=65). Bivariate relationships between programmatic factors and health outcomes were analyzed with  2 statistics using Fisher's exact tests (p<0.05).
