Family nurse practitioners (FNPs) have the potential to provide holistic and family-centered care in Taiwan. This article aims to apply complexity science and systems thinking to the lack of FNPs in Taiwan. The complex problem of having no FNPs and its associated contributing factors are described and visualized through various causal links, patterns, the “fixes that fail” archetype, and the mental model. Based on the authors’analysis of the problem, a multifaceted intervention is recommended.
