RESUMO
PURPOSE: Currently, 7.1 million children in the United States have asthma. Nonadherence to daily controller asthma medication is common, leading to more severe symptoms, overuse of rescue medication, and increased hospitalizations. The purpose of this study was to develop and evaluate the feasibility and acceptability of a novel mHealth management system composed of a sensored device, which is connected to mobile phone app that is designed to monitor and improve asthma medication adherence. PATIENTS AND METHODS: The asthma management system was designed using well-established behavioral theory. Seven adolescents aged 11-18 years were enrolled and given an adherence sensor, and four of those also received a mobile phone app with game features and reminders. Five patients completed the study, and one was lost to follow-up in each group. Mobile app users and their parents participated in focus groups to assess patient preferences. Feasibility was assessed by the ability of sensors to capture real-time medication data. Acceptability was assessed by patient questionnaire and focus group analysis. RESULTS: Successful upload of real-time data from six of seven inhaler sensors to the HIPAA-compliant server demonstrates the feasibility of at-home patient monitoring using the sensor device. All three mobile app users who completed the study reported interest in continued use of the management system and would recommend the app to friends. Unstructured interviews and focus groups revealed that patients felt that the intervention helped their sense of asthma control. CONCLUSION: This study demonstrates the feasibility of using the sensor device to remotely monitor real-time medication usage, and user feedback demonstrates the acceptability of the intervention for patient use. The findings provide guidance for the improvement of study design and technology development. Further research is needed to assess the efficacy of the intervention.
RESUMO
Community engagement strategies and skills can build trust and reduce historical mistrust between researchers, communities, and populations being studied, as well as contribute to the quality of study designs, methods, and dissemination of findings. This review paper discusses why community engagement is of increasing importance in children's environmental health research, describes models and the continuum of methods that are used, and discusses their challenges and benefits. Two case studies, representing different study designs and using different community engagement models and methods, and lessons learned from these cases, are described. Community engagement methods are best understood on a continuum based on the degree to which community members or representatives of community populations are involved in research planning, decision-making, and dissemination. Methods along this continuum include community consultation, community-based participatory research, and community consent to research. Community engagement knowledge and skills are especially important in the conduct of children's environmental health research, with its emphasis on reducing environmental risks at the community level, the increasing focus on genetics and gene-environment interactions, and the importance placed on translation of scientific results into behaviors and policies that protect the community. Across study designs, whether qualitative survey research, an observational epidemiology study, or a randomized intervention trial, understanding community interests, norms, and values is necessary to describe attitudes and behaviors of specific population groups, build evidence of cause and effect between environmental exposures and health, and demonstrate the effectiveness of interventions to reduce risks.
