Development of an advanced practice nurse (APN) role for nutrition management: A needs assessment using a mixed methods approach

Background: Nurses are attributed to play a key role in nutrition management. This field has emerged to be a subject of advanced nursing practice. Aim: Conducting a needs assessment on the role profile of an advanced practice nurse (APN) in nutrition management according to the PEPPA framework. Methods: Mixed methods design. In a cross-sectional study on the current practice, the diagnostic accuracy of nurses' nutrition screening using Nutritional Risk Screening (NRS 2002) compared with independent assessment by a nutrition expert using NRS 2022 was examined. In case of a positive screening result, reasons were determined using an in-depth assessment. In addition, semi-structured, guideline-based interviews were conducted and content-analysed. Results: The identification of patients at risk by nurses' nutrition screening showed a need for improvement (sensitivity: 56%, specificity: 96%; n = 195). Commonly identified reasons for (risk of) malnutrition (n = 51) were lack of desire to eat/lack of appetite or increased caloric needs due to illness. Development opportunities and expectations for an APN were specified based on the interviews (n = 20). They refer to skill enhancement, support within the interprofessional team in complex treatment cases and a stronger nursing role in nutrition management. Conclusions: Based on the needs assessment, the APN's areas of responsibility were identified and assigned to the Hamric model, and implementation strategies could be derived.
