Objective: To identify predictors associated with success of a Nutrition Support Team (NST) for the elderly.
Research methods and procedures:A total of 101 patients who received NST intervention in 2015 were divided into two groups by NST outcome. Patients who achieved therapeutic targets were classified in the success group. Patients who discontinued treatment because of worsening condition or death were classified in the non success group. We assessed patient characteristics, laboratory data, and nutritional support methods. Prior to this study, we retrospectively extracted NST outcome predictors for patients treated in 2014, and identified cutoff values of quantitative variables using receiver operating characteristic analysis. The extracted predictors were as follows: % total energy expenditure (66.0%), albumin (2.4 g/ dL), total lymphocyte count (1,195/µL), C-reactive protein level (2.00 mg/dL), transthyretin level (8.5 mg/dL), Controlling Nutritional Status (CONUT) score (8), and the presence of Peripheral Parenteral Nutrition (PPN). We performed univariate and multivariate logistic regression analysis to identify the factors relevant to NST outcome.
Results:We conducted the multivariate logistic regression analysis adjusted for age, sex, the presence/absence of PPN, and CONUT. A CONUT score ≥ 8 was an independent risk factor for NST outcome (Odds Ratio [OR]: 3.72, 95% Confidence Interval [CI]: 1.26-10.95). Moreover, the presence of PPN tended to be associated with NST outcome (OR: 2.63, 95% CI: 0.96-7.20).
Conclusion:To increase the success rate of NST for elderly, it is important to identify the elderly at risk of non success NST outcome.
