- Nutritional decline associated with non-surgical cancer treatment has been well documented. The implementation of an evidence-based nutrition care pathway is one approach suggested to improve the nutrition outcomes of this group of patients. We aimed to systematically review published original research to determine whether evidence-based nutrition clinical care pathways, as compared with usual care, improve outcomes for patients receiving non-surgical cancer treatment. The review was registered with PROSPERO (CRD42017048816) and followed PRISMA guidelines. The search strategy was conducted in four databases, and supplemented by an internet search, from inception to October 2016. Study quality was assessed using the Quality Criteria Checklist for Primary Research. Results were synthesized descriptively. Six reports of five studies formed the final library with a range of interventions and control practices investigated across several diagnostic groups. Nutrition outcomes were reported using multiple approaches with either no effect, or in favor of the clinical pathway intervention. Risk of bias was low in two studies with some risk in the remaining three studies. It was not possible to determine whether the effect on nutritional outcomes was attributable to care pathway implementation. The need to extend the evidence base through high-quality clinical trials was evident.
