Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Objectives: The primary objective of this study is to determine how best to define nutritional risk (i.e., risk for adverse clinical outcomes due to inadequate nutrient intake) among older VA TCU residents. As part of this objective, we will seek to develop a better understanding of the interrelationship between nutrient intake, weight change, serum concentration of albumins, health status/illness severity, and mortality. The secondary objective is to develop a prediction model for identifying which TCU residents are likely to have ongoing problems with low nutrient intake. The ultimate objective is to develop a clinically useful system to identify residents who are likely to benefit from specific interventions aimed at improving nutritional risk.

Objectives: The primary objective of this study is to determine how best to define nutritional risk (i.e., risk for adverse clinical outcomes due to inadequate nutrient intake) among older VA TCU residents. As part of this objective, we will seek to develop a better understanding of the interrelationship between nutrient intake, weight change, serum concentration of albumins, health status/illness severity, and mortality. The secondary objective is to develop a prediction model for identifying which TCU residents are likely to have ongoing problems with low nutrient intake. The ultimate objective is to develop a clinically useful system to identify residents who are likely to benefit from specific interventions aimed at improving nutritional risk.
Methods: To meet these objectives, 400 older, non-terminally ill veterans admitted to a VA TCU (where average length of stay is approximately 90 days) will be prospectively studied using the same methodologic approach validated in prior VA hospital-based investigations. After completing a comprehensive admission assessment, each subject will be monitored closely throughout his/her TCU stay with serial nutrient intake and recurring metabolic, functional, neuropsychological, cognitive, nutritional, and medical assessments. Weights, anthropometrics, and blood for serum proteins, inflammatory markers (e.g., cytokines), and other select lab indices will be obtained at least monthly until discharged. Resting metabolic rate (by indirect calorimetry) will be obtained on select residents. Each subject will remain in the study for 12 months. From discharge through the end of the subject's study year, each subject will be monitored by phone to determine survival and days of institutional (e.g., hospital, NH) care. At study's end, strengths of associations will be assessed using univariable and multivariable analytic techniques including logistic and Cox Proportional-Hazards analyses.
Findings: See citations linked.
Status: Status: Funding began 9-1-2005. Subject recruitment began 3-1-2006. To date, we have recruited 446 subjects into the study. 446 subjects have been discharged from the inpatient phase of the study. The average length of stay for these subjects is 32 days.
Impact: Our study will provide a clearer understanding of what factors contribute to the apparent nutritional deficits seen in many older veterans residing in VA nursing home TCUs. The study will also lead to the development of a clinically useful system to identify TCU residents who are likely to benefit from specific interventions aimed at improving nutritional risk and thus clinical outcomes.
