Stakeholder engagement is a key component in developing educational initiatives aimed at improving adolescent and young adult (AYA) comprehensive care. This project describes a systematic approach to and evaluation of stakeholder engagement in the development of female AYA sexual and reproductive health (SRH) training for interprofessional cystic fibrosis (CF) healthcare providers. Key stakeholders iteratively developed the goals and objectives and discussed preferred educational strategies of a SRH training program using the Kern approach to curriculum development for medical education.1 This six-step approach consists of: 1) problem identification, 2) a targeted needs assessment of learners, 3) development of curricular goals and objectives, 4) selection of educational strategies, 5) implementation of training, and 6) evaluation and feedback. Process measures for stakeholder involvement (stakeholder recruitment, composition, co-learning, and transparency) and immediate outcomes (impact on the development process and satisfaction) were measured via recorded stakeholder recommendations and a survey. Sixteen stakeholders (2 adult women with CF, 4 mothers of AYA women with CF, 3 pediatric pulmonologists, 2 adult pulmonologists, a CF social worker, a CF dietitian, an adolescent medicine physician, an expert on disability, and a medical education expert) participated in this project. Attendance during 3 group conference calls ranged from 10-12 stakeholders. A nearly equal mix of patients/parents, healthcare providers, and experts attended all calls. Twelve participants completed the stakeholder survey. A majority of stakeholders understood their roles, had their expectations for the project met or exceeded, and were satisfied with the frequency and quality of engagement in the project. All stakeholders provided multiple concrete recommendations during the development process. Stakeholders generated a user-empathy map outlining the feelings, pain points, influences, goals, and tasks of interprofessional CF providers related to the provision of female SRH care. The group reviewed prior research identifying the needs and preferences of interprofessional CF providers regarding SRH training. Stakeholders developed specific training goals and objectives to enhance the capacities of all members of the interprofessional CF care team around their: 1) SRH knowledge, 2) perspectives, and 3) communication skills. The group also discussed educational strategies to achieve the outlined objectives. Stakeholders favored a mixed approach offering web-based and in-person learning opportunities (such as interactive webinars, regional workshops, or presentations at national meetings). This project utilized systematic stakeholder engagement in the development of training for interprofessional CF providers centered on female AYA SRH. The intentional process for engaging patients/parents, healthcare providers, and discipline experts can be implemented for similar educational programs seeking to improve AYA care. 1Kern DE et al.
