Objective To explore the experiences of specialist nurses in delivering continuity care for chronic wounds within a cross-regional specialist alliance and analyze their adaptive mechanisms using Complex Adaptive Systems (CAS) Theory.Methods A descriptive qualitative research was adopted.Semi-structured interviews were conducted with 14 wound specialist nurses from 14 medical institutions across 7 provinces in China, and content analysis was used to refine themes.Results A total of three main themes and six subthemes were identified:role reconstruction and competency iteration of adaptive agents (role strain fostered versatile professionals, system restructuring drived knowledge renewal); formation of non-linear collaborative networks (rapid response highlighted synergy advantages, contractual spirit drived collaborative effects); innovation emergence of technical achievements (technological innovation solved grassroots resource problems, model innovation enhanced nursing effectiveness).Conclusion In the complex cross regional specialist alliance collaboration model, specialist nurses continuously adapt to their roles and task requirements through the interaction of cognition and action in providing chronic wound continuity care services, promoting their personal growth and organizational adaptation.It is suggested to strengthen role expansion and capability enhancement trai-ning within specialist alliances, improve alliance mechanism construction, promote knowledge sharing, and advance the clinical application of innovative results to enhance chronic wound management effectiveness.
