Coalitions develop in and recycle through stages. At each stage (formation, implementation, maintenance, and institutionalization), certain factors enhance coalition function, accomplishment of tasks, and progression to the next stage. The Allies Against Asthma coalitions assessed stages of development through annual member surveys, key informant interviews of 16 leaders from each site, and other evaluation tools. Results indicate all coalitions completed formation and implementation, six achieved maintenance, and five are in the institutionalization stage. Differences among coalitions can be attributed to their maturity and experience working within a coalition framework. Participants agreed that community mobilization around asthma would not have happened without coalitions. They attributed success to being responsive to community needs and developing comprehensive strategies, and they believed that partners' goals were more innovative and achievable than any institution could have created alone.

Allies Against Asthma coalitions each employ a community health worker (CHW) program as part of its community action plan. The structure and management of CHW programs vary in response to the resources and needs of the local community, as do the roles and characteristics of the CHWs hired. All programs utilize CHWs to provide community-based education and/or outreach to community members, primarily in their homes. Using an asthma action plan, most Allies CHW programs function as an extension of and link to the clinician, providing basic asthma education and care coordination in a supportive, family-friendly setting, context, and location. Community health workers rely heavily on relationship building and family empowerment to assist families in improving asthma control. Working within a coalition framework helps integrate the CHW program into other services and resources in the community. As participants in coalition activities, CHWs often bring an important and meaningful viewpoint to the coalition.
