Investigating key factors of feeding intolerance in severe acute pancreatitis: A scoping review

BACKGROUND: The complexity of severe acute pancreatitis (SAP) and the stress caused by the disease is associated with a high incidence of feeding intolerance. However, the factors influencing feeding incontinence in patients with SAP are diverse. AIMS: To systematically analyse relevant studies that investigate the occurrence of feeding intolerance in patients with SAP, identify the relevant factors of feeding intolerance in such patients and provide a reference for nursing staff to develop relevant intervention measures. DESIGN AND METHODS: This scoping review followed the approach proposed by Arksey and O'Malley. Seven electronic databases were searched from their establishment until August 2023. This included research on the factors influencing feeding intolerance in patients with SAP, determining research questions, completing literature screening and quality evaluation, extracting data and summarizing and analysing the data. The PRISMA extension for scoping reviews (PRISMA-ScR) statement has also been included. RESULTS: A total of 23 articles were included. The factors influencing feeding intolerance in patients with SAP included the patient's condition, disease, treatment, feeding management and follow-up care. CONCLUSIONS: The factors affecting feeding intolerance in patients with SAP are multifaceted. A personalized nursing care plan should be developed based on relevant risk factors to improve feeding tolerance and comfort in patients with SAP and shorten hospitalization time. RELEVANCE TO CLINICAL PRACTICE: Intensive care nurses should identify the risk factors for feeding intolerance in patients with SAP and implement appropriate interventions. To identify the risk factors, nurses must be updated with courses and training. Moreover, a systematic feeding intolerance prediction program can help intensive care nurses effectively identify the risk factors for feeding.
