Bridging the gap between research and practice for nutrition support after pelvic exenteration surgery

Current best practice for postoperative feeding in surgical patients is well established, however implementation of evidence-based practice comes with many challenges. A common barrier is surgeon adherence to guidelines and the reasons behind this are not well understood. Pelvic exenteration surgery is a complex surgery and postoperative feeding methods in this patient cohort vary significantly from patient to patient. The aim of this study was to identify barriers and enablers for surgeons to implement evidence based feeding methods after pelvic exenteration surgery and provide practical strategies for non-surgeon healthcare workers to improve compliance.

A qualitative study was conducted by performing semi-structured interviews with 12 Consultant Surgeons at hospitals in Australia and New Zealand with dedicated pelvic exenteration services. Deductive and inductive thematic analysis was performed in line with the Theoretical Domains Framework and Behaviour Change Wheel model to identify relevant domains, themes and intervention functions.

Culture was identified as an overarching theme that influenced postoperative feeding practices, surgeon behaviours and sub-themes. Identified sub-themes included motivation, relationships and expectations, environment and 'moving forward'. Motivations to use different types of feeding routes postoperatively varied across hospitals. Relationships, surgeons' expectations and the environment all influenced the way in which patients were fed postoperatively. Practical strategies were identified to assist non-surgeon healthcare workers achieve positive change moving forward with postoperative feeding.

Practical strategies to promote enablers and reduce barriers are required to bring about positive change and align practice with the evidence.
