OBJECTIVE: The primary objective of this study was to assess the use of Subjective Global Assessment to identify nutrition-associated complications and death in a geriatric population. A secondary objective was to evaluate the ability of Subjective Global Assessment to identify geriatric residents of long-term care facilities who were undernourished or at risk for developing undernutrition. METHODS: Fifty-three consecutive residents who were > or = 65 years of age and had been residing in a long-term care facility for < 2 weeks were enrolled in the study. The Subjective Global Assessment Classification technique was performed according to the procedure outlined by Detsky and colleagues. Residents were classified as well-nourished (A), mild/moderately undernourished (B) or severely undernourished (C). In addition, a Subjective Global Assessment Composite Score was derived. Subjective Global Assessment measures were compared with two traditional objective measurements of nutritional status: serum albumin and serum total cholesterol. Outcome measurements of nutrition-associated complications were determined over a 3-month period by recording the incidence of major infections, decubitus ulcers, nutrition-related hospital readmissions, and mortality. RESULTS: Sixteen residents (30.2%) were categorized as Subjective Global Assessment class A, 28 residents (52.8%) were class B, and 9 residents (17%) were class C. A significant association was found between nutritional status as determined by Subjective Global Assessment Composite Score and nutrition-associated complications (p<0.05). Subjective Global Assessment Classification was related to death (p<0.05) with severely undernourished residents having the highest mortality rate. Hypoalbuminemia only demonstrated a significant relationship with nutrition-associated complications (p<0.05), whereas hypocholesterolemia was associated with death (p<0.05). CONCLUSIONS: Subjective Global Assessment of nutritional status appears to be a simple, noninvasive and cost-effective tool for assessing nutritional status of geriatric residents in long-term care facilities. This assessment tool is also beneficial for identifying patients with increased risk of nutrition-associated complications as well as death.
