The Quality of care for older adults in in patient geriatric settings relies heavily on well – structured workflows and a lived person-centred approach. This project describes the adaptation of nursing processes on a geriatric ward in a Swiss hospital for acute Geriatric medicine, using the methodology of Practice Development (PD) according to Brendan McCormack and Tanja McCance. The aim was to implement sustainable improvements in daily nursing routines through participatory process and the integration of Lean principles. As part of a continuous improvement process (CIP), a small working group which consist of nurses with different grades was established. Based on a joint analysis of the current situation, key areas for action were defined. Central to the project was the optimization of workflows in early and late shifts. Lean management tools such as a “regular flow” at defined times and structured daily huddles for communication and reflection were introduced. Furthermore the 7 P (Person, Plan, Priority, Personal hygiene, Pain, Position, Presence) and the 5 P (Priority, Personal hygiene, Pain, Position, Presence) methods were applied to address both organizational and cultural dimensions. The implementation led to greater role clarity, improved transparency, better communication, and a noticeable reduction in stress among team members. Staff reported increased job satisfaction and improved collaboration. The combination from values-based Practice Development with structured process optimization proved particularly effective for achieving sustainable change in everyday nursing practice.This project exemplifies how the integration of Practice Development, Lean thinking, and participatory teamwork can enhance the quality of care in geriatrics while simultaneously improving working conditions for nurses within a short time.
