No chance for pneumonia - A campaign for mobilization in the context of a practice project addressing pneumonia prevention Abstract. Background: Healthcare-associated infections (HAI) in inpatients are associated with complicated treatment. In Europe, 5.5 % of inpatients develop HAI. About half of these infections could be avoided. In the Clinic for traumatology of the university hospital Zurich, we developed interventions to reduce HAI. Thereby, we focused on non-ventilator-associated hospital-acquired pneumonia (nvHAP). Aim: Besides reducing nvHAP rates, we intended to improve patient mobility, to empower nurses, and to strengthen interprofessional collaboration. Methods: To achieve these aims, we performed a practice development project comprising inhouse training, workshops, information posters, structural changes and a mobilization campaign. Results: Patient mobilization increased by 40 %, duration of mobilization sessions by 46.5 %. The semi-annual comparison shows a sustainable improvement of 7.6 %. Nurses reported knowledge gain, considerably improved interprofessional collaboration and increased quality of caring. Discussion: Combining various methods and following an interprofessional approach resulted in sustainable effects. Limitations and transfer: Targeted practice development proves to be suitable for promoting patient mobility. Regular repetitions and physiotherapy services at off-peak times are essential to ensure sustainability.
