Focus Groups. As the second step in the development of the application, the investigators will conduct three focus group sessions. All focus groups will be designed and moderated by Baltimore Research, a full service marketing research company with over 50 years of experience (See Facilities and Other Resources for further details). Baltimore Research will also handle all data collection and analysis for the focus group sessions and provide the study team with a final report for each session. Each focus group will include a relatively homogeneous set of stakeholders: Physicians/primary care staff, health administrators (e.g., see Priority Partners letter of support), and patients, respectively. All focus groups will include approximately eight participants, as this has been identified as an ideal number of participants in a focus group session. In order to ensure that approximately eight participants will be included, the investigators will attempt to recruit at least 10 participants, because all participants must show up at the same time for a specific scheduled session, and this usually results in some people who agree to participate but do not show up at the scheduled time. These groups will be held as one-time sessions designed to generate ideas that will enhance the application's usability and adoptability from the perspective of the professionals who are most likely to be involved in the institutional decision making processes relevant to the dissemination of the proposed intervention. The investigators anticipate that recruitment of health professionals will be straightforward given our extensive connections to professionals throughout the local health care systems in Baltimore, and consultation by Baltimore Research will ensure that these recruitment processes are free of bias. The third focus group session (patients) will be the beginning of an iterative process in which the investigators first solicit ideas about the functionality and interface of the application. Participants for this focus group will be recruited using methods identical to those described below for the pilot randomized controlled trial.
