Design and rationale of the effect of early nutritional therapy on frailty, functional outcomes and recovery of malnourished medical inpatients trial (EFFORT): a pragmatic, multicenter, randomized-controlled trial

Background: Malnutrition is highly prevalent and strongly associated with clincial outcomes of medical inpatients. Still, the benefit of nutritional treatment to prevent adverse outcomes in medical inpatients at risk for malnutrition remains unproven. We describe the trial methods of the largest yet nutritional trial in medical inpatients including the rationale for key design decisions regarding the nutritional strategy, eligibility criteria, choice of control arm, and endpoints. Methods: The Effect of early nutritional therapy on Frailty, Functional Outcomes and Recovery of malnourished medical inpatients Trial (EFFORT) is an investigator-initiated, non-commercial, open-label RCT to compare the effects of an intensified nutritional therapy (intervention group) with a control group on medical outcomes. We include adult medical inpatients at risk of malnutrition based on a Nutritional Risk Screening 2002 (NRS) score of ≥3 points with an expected length of stay of ≥5 days. An individualized systematic nutritional assessment by study dieticians is done to define nutritional targets and to establish an implementation plan. Patients in the intervention group receive individualized early nutritional therapy based on a previously published consensus algorithm, while control group patients receive standard hospital nutrition. The study is powered to compare clinical outcomes (composite adverse outcome and mortality) in the 2 study arms as well as to address several mechanistical questions. Conclusion: EFFORT aims to close important gaps in the literature regarding the controversy about benefit and possible harm of nutritional therapy in medical inpatients at risk for malnutrition.
