Objectives: To investigate the effect of a nutrition intervention program for geriatric nutritional at-risk patients., Design: A randomized controlled trial., Setting: Department of geriatric medicine in a university hospital and in the primary healthcare sector, Copenhagen., Subjects: Geriatric patients ( N = 144) at nutritional risk., Intervention: The intervention consisted of an individual dietary plan for home, including pre-discharge advice on nutritional intake, combined with three follow-up visits after discharge (one, four, and eight weeks)., Main Measures: Change in body weight, Barthel Index, hand-grip strength and self-rated health from baseline (discharge) to three months after discharge, readmission, and mortality (90 and 120 days)., Results: The mean (SD) age in total sample was 87.2 (6.2) years. Sample size in the intervention group (IG) was N = 72, and in the control group (CG), N = 72. IG had a mean (SD) weight gain of 0.9 (4.2) kg compared to a weight loss of 0.8 (3.6) kg in the CG ( P = 0.032). In addition, an improvement in self-rated health was seen in the IG compared to CG (IG: 23 (47%) vs. CG: 12 (24%); P = 0.021). No significant difference between groups was found in functional status, mortality, or readmission rates., Conclusion: An individual dietary plan based on everyday food, combined with three follow-up visits (one, four, and eight weeks) after discharge, led to an improvement in nutritional status and self-rated health in geriatric patients.
