As the application of citizen science expands to address increasingly complex social problems (e.g., community health), there is opportunity to consider higher-order engagement beyond that of individual members of a community. The US Environmental Protection Agency (EPA) is working to foster public engagement in science through Smoke Sense, which is a citizen science research project that aims to reduce the public health burden of wildland fire smoke. Smoke Sense is facilitated by a mobile app that shares information on air quality, smoke, and health, and collects individual reports of smoke exposure and concurrent health symptoms. However, Smoke Sense is also generating interest among organizations that are working in this problem domain at the local, state, national, and tribal levels. The interest in the citizen science project at the organizational level led us to ask: What would motivate members of organizations to engage in a citizen science project like Smoke Sense, and how do they envision that engagement could improve public health? To explore these questions, we collected data through interviews with individuals who were engaged in Smoke Sense through their work at local, state, and tribal environmental and health agencies in the western US. An inductive, thematic analysis suggests that individuals' motivations stem from their e xperiences and challenges with smoke in their different roles (e.g., personal, professional, and community member). Respondents envisioned leveraging both the app itself and the data generated by individuals in their region to enhance and support their existing outreach and communication efforts related to smoke. Citizen science projects that aim to address issues in complex problem domains should be designed to complement the work of partner organizations.

There is ample evidence of adverse cardiovascular health outcomes associated with exposure to air pollution and cardiac rehabilitation patients are at increased risk for future adverse health events related to air quality. Risk communication and health messaging about recommended behaviors to reduce exposure to air pollution can be integrated into existing care routines and structures. How this can be achieved most appropriately and effectively is not well understood. A focus group design is used to investigate cardiovascular patient and provider experiences, attitudes and beliefs about the risks of air pollution, related health risk messaging and factors that may influence integrating that topic into patient care and communication. Three discussions were hosted, one with cardiac patients, a second with non-physician cardiac rehabilitation providers and a third with physicians who treat cardiac patients. A within-case thematic inductive analysis of each discussion is used to understand the nature of communication, logistics, guidance and overall substance of the cardiac rehabilitation educational experience. Results suggest that air pollution may be an unrecognized risk factor for cardiac patients and cardiac rehabilitation is a prime setting for communicating air pollution health risk messaging. However, to effectively integrate air quality health risk messaging into cardiac rehabilitation, it is critical to account for the existing knowledge-base and behaviors of both providers and patients.
