RESUMEN
OBJECTIVE: To determine the relationships between malnutrition and nutrition-related conditions according to the European Society of Clinical Nutrition and Metabolism (ESPEN) consensus and guidelines and clinical outcomes in postacute rehabilitation. METHODS: Of 102 eligible inpatients, 95 (84.5 years old, 63.2% women) fulfilled inclusion criteria: aged ≥70 years, body mass index <30kg/m2, admission for rehabilitation. Mini-Nutritional Assessment-Short Form (MNA-SF≤11) identified patients "at risk" and ESPEN basic and etiology based definitions were applied. Nutrition-related conditions (sarcopenia, frailty, overweight/obesity, micronutrient abnormalities) were determined. We assessed the relationship between these conditions and the clinical and rehabilitation outcomes (relative functional gain, rehabilitation efficiency) during hospitalization. RESULTS: All patients were "at risk" by MNA-SF criteria and 31 reported unintentional weight loss >5% in the last year or 2-3kg in the last 6 months. Nineteen fulfilled the ESPEN basic definition, of which 10 had disease-related malnutrition with inflammation and 9 without inflammation, and 20 had cachexia. Sarcopenia (n=44), frailty (n=94), overweight/obesity (n=59), and micronutrient abnormalities (n=70) were frequent. Unintentional weight loss impaired all functional outcomes and increased length of stay [OR=6.04 (2.87-9.22); p<0.001]. In multivariate analysis, relationships between rehabilitation impact indices and the ESPEN basic and etiology-based definitions observed in univariate analysis persisted only (and marginally) for relative functional gain [OR=13.24 (0.96-181.95); p=0.005]. Infrequent in-hospital mortality prevented meaningful analysis of this outcome. CONCLUSIONS: ESPEN basic and etiology-based definitions and nutrition related disorders were determined in postacute care. Malnutrition was associated with poor rehabilitation outcomes, mainly due to unintentional weight loss.
