Background: Recently, numerous initiatives have been taken to improve food and meals for hospital inpatients. Research providing in-depth knowledge on leading such improvement initiatives and implementing changes, specifically through facilitation within this multilevel context, is essential. This study aims to explore nutrition leaders' experiences in implementing changes to improve food and meal provision for hospital inpatients, focusing on facilitation activities.

Method: This is a qualitative interview study within the social constructivist paradigm. Participants were recruited through professional networks, advertisements, and snowballing. Eighteen semi-structured interviews were conducted individually with participants in leadership roles of food and meal improvement initiatives at Swedish hospitals. The interviews were transcribed verbatim and analysed thematically through an i-PARIHS lens.

Results: Three themes of facilitation activities were identified: 'Building Relationships', 'Placing Food and Meals on the Agenda', and 'Cultivating Skills'. Building relationships involved establishing connections between the service and clinical divisions. Creating common structures and multidisciplinary teamwork enabled collaboration across organisational boundaries. Placing food and meals on the agenda involved both initial and ongoing communication activities, as food and meal tasks were often considered low priority. Cultivating skills encompassed creating learning opportunities for implementing lasting changes, tailored to specific contexts and adopted within everyday practices.

Conclusions: Collaboration between foodservice and clinical professionals, along with the dissemination of knowledge, appears to be important for implementing changes. Active leadership supports successful implementations by providing structured approaches, including feedback systems, and by contributing to the recognition of improvement initiatives, according to experiences shared during interviews.
