Background: In Switzerland, the growing prevalence of chronic conditions leads to care fragmentation, a challenge particularly acute in home care networks with geographically dispersed teams. A unified Professional Practice Model (PPM) grounded in person-centred values offers a strategic solution to bridge practice, enhance care cohesion, and align organisational goals. This study aimed to develop and conduct a contextual analysis for implementation of a person-centered professional practice model for home care services in French-speaking Switzerland. Methods: A multi-method, empirical study was conducted in a large home care service. The PPM was developed using concept mapping, a participatory process involving 157 healthcare professionals. Subsequently, a contextual analysis for implementation was performed using the Intervention Mapping framework, which included focus groups with stakeholders and frontline staff (n=14), and validation through a modified Delphi process. Results: The concept mapping yielded 14 core values, with "health promotion" (rated 4.4/5) and "patient-centred approach" (4.3/5) identified as most important. "Interprofessionalism" received the lowest rating (3.7/5), highlighting a key implementation challenge. The contextual analysis revealed strong leadership support (83% agreement) and a culture of psychological safety (83% agreement) as critical facilitators. A key finding was the spontaneous alignment of our empirically derived model with McCance and McCormack's Person-centred Practice Framework, providing theoretical validation. Eight concrete implementation strategies were co-designed and validated. Conclusion: This study demonstrates a feasible, staff-driven process to translate professional values into a coherent PPM. The model serves as a practical framework to reduce care fragmentation by establishing shared priorities that bridge practice across a decentralized organisation. This work provides a validated roadmap for knowledge translation, demonstrating how to connect the practice environment with organisational strategy and governance to foster sustainable person-centred care.
