Objective: Nurse executives (NEs) working at rural medical facilities encounter challenges, including nursing quality and management, due to a shortage of nurses; this requires them to develop their competencies. A previous study reported that managers working in rural medical institutions gather nearby to learn about management. However, no research has focused on NEs working in rural areas or clarified their experiences in developing competency through learning networks. This study focused on the learning networks of NEs working in rural medical facilities and aimed to clarify their experiences with competency development.Patients/Materials and Methods: In this study, we conducted competency development for NEs through the learning networks in Japan. An ethnographic qualitative study design was used. Twenty NEs participated in the study. Data were collected through participant observation and ethnographic interviews, and analyzed using thematic analysis.Results: This study revealed the following three themes: (1) aiming to provide medical care that contributes to the rural community; (2) work efficiency by a small number of staff; and (3) development as NEs. The NEs in this study improved as NEs by promoting efficiency in their work with a small group, while aiming to provide medical care that contributes to the rural community through participation in a learning network.Conclusion: A learning network of NEs develops their competencies by helping them improve their practice through dialogue and reflection on their nursing management. Therefore, even in an environment with limited resources, NEs might be able to improve the services of their organization through the learning network.
