[Success factors and obstacles in the implementation of the "Lübeck Worlds of Movement Model" in inpatient care facilities-results of a scientific evaluation].

The Prevention Act has greatly promoted the implementation of interventions focusing on the physical activity of nursing home residents. However the goal-compliant implementation and long-term sustainability of such offers is often associated with major challenges.Over a period of 2.5 years, the program "Lübeck Worlds of Movement Model" was evaluated during its implementation in nursing homes in the city of Lübeck. The main objective was to discover promoting or inhibiting factors of the implementation process. Alongside other data collection, 52 partially structured, problem-oriented interviews were conducted with participating professionals (e.g., employees of the nursing homes, trainers). They were analyzed and structured in a topic-based manner.A number of promoting and inhibiting factors were identified. The structure of the program supports the participants' and trainers' motivation to stick to the program. However, it was not well received nor permanently adopted in all areas of the nursing homes. The lack of involvement of nursing staff and of anchoring the program in the organizational structure and culture of the facilities were two of the most important inhibiting factors. Furthermore the model is suitable only for a limited number of residents. Further adaptations and developments have to be tackled to meet the target group's needs and achieve the successful implementation and long-term sustainability of the program.
