Background/rationale:
Malnutrition is prevalent in patients undergoing reconstruction surgery for head and neck cancer (HNC), negatively impacting outcomes. Despite the availability of evidence-based guidelines (EBGs), evidence-practice gaps persist. This study examined the feasibility of implementing a pre-operative nutrition evidence-based care pathway (EBCP).
Methods:
This mixed-methods, pre-post study included a retrospective audit (Jan-Dec 2023) and prospective pilot implementation of a pre-operative, supportive care-led clinic (Oct 2024-Jan 2025). Nutrition care processes (referrals, malnutrition screening and nutrition assessment with validated tools) were benchmarked against Clinical Oncology Society of Australia (COSA) EBGs. Clinical outcomes (complications, length of stay (LOS) and readmissions) were explored. A survey of multidisciplinary team (MDT) members examined the perception of the importance of nutrition, clinician roles and responsibilities and barriers to screening and assessment using the Capability, Opportunity, Motivation-Behaviour (COM-B) model. Subsequent MDT engagement informed the EBCP, guided by the Action, Actor, Context, Target, Time (AACTT) Implementation Framework.
Impact on practice:
Pre- (n=115, 56% male, mean (SD) age 62 (15) years) and post-implementation (n=41, 64% male, 62 (14) years) cohorts were included. All pre-operative nutrition care processes improved following EBCP implementation, including referrals (64% vs. 95%, p<0.001) and malnutrition screening (91 vs. 98%, p=0.14). False negative screening reduced (22% vs. 10%, p=0.13) and median time from screening to surgery increased (0 vs. 5 days, <0.001). Nutrition assessment with a validated tool increased (13% vs. 80%, p<0.001). Survey responses pre- (n=11) and post- (n=8) implementation indicated improved perception of the service and fewer barriers to screening and assessment. All respondents agreed that the service met patient’s nutrition care needs following EBCP implementation.
Discussion:
Implementing a pre-operative nutrition EBCP is feasible, improves adherence to evidence-based nutrition care for patients with HNC and has potential to improve patient outcomes. This model may be transferrable to other areas of cancer care.
