Study protocol of a prospective observational study on the impact of specialized nutritional care on the 3-month outcomes of patients at high risk of malnutrition admitted to a rehabilitation hospital

Aim Malnutrition is an often underestimated, worldwide, frequent problem with a high prevalence among inpatients, especially the elderly ones. Undernourished patients have an increased risk of comorbidities, complications and a decreased quality of life. Malnutrition is associated with longer hospital stay, increased care needs and costs for the National Health Service (NHS). We describe the protocol of a study conducted to evaluate the impact of specialized nutritional care on 3-month outcomes of patients at high risk of malnutrition at admission and to describe the actual nutritional practice in a rehabilitation setting. Methods In this single-center, prospective, observational study patients at high risk of malnutrition who received standard nutritional care (Group 1) were compared with patients at high risk of malnutrition who received a specialized nutritional care (Group 2). Three months after discharge (follow-up), patients of both groups were interviewed by telephone to collect data regarding number of hospital readmission, emergency department admission, general practitioner (GP) and outpatient visits, diagnostic tests, daily medication use and survival. Conclusion Our study could help to support clinical choices for personalized nutritional interventions to improve rehabilitation outcomes and to decrease the costs for the NHS. This protocol is registered at ClinicalTrials.gov (NCT07183098) under the title “A Prospective Observational Study on the Prevalence of Malnutrition and Clinical-Economic Aspects of the Impact of Specialized Nutritional care on the 3-month Outcomes of Patients at high Risk of malnutrition Admitted to a Rehabilitation Hospital”.
