Nutritional indices (percentage ideal body weight [IBW], serum albumin, serum transferrin, total lymphocyte count [TLC] and delayed cutaneous hypersensitivity [DH] response)were assessed in 80 consecutive patients(aged 85-100 y) within 24 h of admission to determine their predictive value for mortality. Nine patients died. Pearson correlation analysis demonstrated that death was significantly (p < 0.05 to < 0.01) associated with sepsis, serum albumin < 30 g/L, TLC ≤ 1500 cells/mm³, and percentage IBW ≤ 90%. However, when serum albumin was controlled for, logit regression analyses demonstrated that the impact of other nutritional indices on death was insignificant. The effect of serum albumin remained significant (p <0.05 to <0.01) even when age and physician's diagnosis were held constant. With the logit model, serum albumin ≤ 30 g/L had a sensitivity of 0.33, specificity of 0.99, and overall predictive power of 0.91. Serum albumin is thus the simplest and best single predictor of mortality and can provide early identification of elderly people at increased risk of death. [ABSTRACT FROM AUTHOR] |
