Implementing early feeding after liver transplant using implementation frameworks: A multimethod study

Abstract

BackgroundEvidence‐based guidelines (EBGs) in the nutrition management of advanced liver disease and enhanced recovery after surgery recommendations state that normal diet should recommence 12–24 h following liver transplantation. This study aimed to compare postoperative nutrition practices to guideline recommendations, explore clinician perceptions regarding feeding after transplant surgery, and implement and evaluate strategies to improve postoperative nutrition practices.MethodsA pre‐post multimethod implementation study was undertaken, guided by the knowledge‐to‐action framework. A retrospective chart audit of postoperative dietary practice and semistructured interviews with clinicians were undertaken. Implementation strategies were informed by the Consolidated Framework for Implementation Research–Expert Recommendations for Implementing Change matching tool and then evaluated.ResultsAn evidence‐practice gap was identified, with the median day to initiation of nutrition (free‐fluid or full diet) on postoperative day (POD) 2 and only 25% of patients aligning with the EBGs. Clinician interviews identified belief in the importance of nutrition, with variation in surgical practice in relation to early nutrition, competing clinical priorities, and vulnerabilities in communication contributing to delays in returning to feeding. An endorsed postoperative nutrition protocol was implemented along with a suite of theory‐ and stakeholder‐informed intervention strategies. Following implementation, the median time to initiate nutrition reduced to POD1 and alignment with EBGs improved to 60%.ConclusionThis study used implementation frameworks and strategies to understand, implement, and improve early feeding practices in line with EBGs after liver transplant. Ongoing sustainability of practice change as well as the impact on clinical outcomes have yet to be determined.
