Objective: To investigate the association between serum albumin, prealbumin, various serum inflammation associated-cytokines, and mortality in older geriatric recuperative care patients., Design: A prospective cohort study., Setting: A geriatric rehabilitation unit of a university-affiliated Department of Veterans Affairs hospital., Participants: Participants were 53 geriatric patients (mean age 78 +/- 7.3, 96% male) admitted to a Geriatric Evaluation and Management (GEM) unit. Patients with documented near-terminal medical disorder, overt infections, and any systemic or localized inflammatory disorders were excluded., Measurements: Inflammation-associated cytokines (IL-8, IL-1beta, IL-6, IL-10, TNF-alpha), albumin, prealbumin, and C-reactive protein were measured at hospital discharge and each subject was then tracked for 1 year., Main Results: By Cox Proportional-Hazards Regression analysis, the strongest predictor of mortality within 6 months of study entry was the serum IL-6. For each log increase in IL-6, there was nearly a 9-fold greater 6-month mortality risk (RR 8.99, 95% CI 1.65 to 49.03). The association between albumin and mortality was no longer significant after controlling for IL-6. There was a strong inverse correlation between IL-6 and both albumin (R2 0.39, P < .001) and prealbumin (R2 0.41, P < .001)., Conclusion: Subclinical inflammation appears to be an important factor contributing to low serum albumins in older recuperative care patients and may confound the association between albumin and mortality in this population. More in-depth studies of these associations are warranted.

Objectives: To evaluate the prognostic significance of weight change in frail elderly patients., Design: Prospective study., Setting: The general medical or surgical wards of a university-affiliated Department of Veterans Affairs hospital., Participants: Six hundred sixty randomly selected subjects aged 65 or older., Measurements: At admission and discharge, each subject completed a standardized diagnostic evaluation, including demographic variables, and basic medical, functional, and nutritional assessments. Weights were recorded from hospital or clinic visits in the year before admission, during the current hospitalization, and after discharge for a median of 5.6 years. Average yearly intraindividual weight change was calculated using least-squares regression. Associations between intraindividual weight change and mortality were identified using Cox proportional hazards regression., Results: During the study, 314 subjects (48%) died. A U-shaped association between weight change and mortality was observed. Those who were relatively weight stable (+/-1 kg/y) had the lowest mortality (28%). Compared with this group, the adjusted relative risks (ARR) of death for those who lost 1 or more to less than 3 kg/y and 3 or more kg/y were 2.14 (95% confidence interval (CI)=1.52-3.00) and 3.59 (95% CI=2.58-4.99), respectively. The ARR associated with a weight gain of 1 or more to less than 3 kg/y and 3 or more kg/y was 1.38 (95% CI=0.91-2.10) and 3.73 (95% CI=2.34-5.94), respectively. The amount of bidirectional weight fluctuation (estimated using coefficient of variance) was not significantly associated with mortality., Conclusion: For reasons that are not clear, elderly patients who gain 3 or more kg/y after hospital discharge are at nearly the same risk of mortality as those who lose this amount of weight.

Background: The importance of undernutrition as a determinant of postdischarge mortality among hospitalized elderly people remains controversial. The purpose of this study was to investigate this issue., Methods: The study included 660 elderly patients (85% white, 98% men, average age 73 +/- 6 years) discharged from a university-affiliated Department of Veterans Affairs Hospital, who were followed for 1 year. Associations between patient characteristics at hospital discharge and mortality were identified utilizing Cox Proportional Hazards Regression analysis., Results: In the year following hospital discharge, 85 subjects (13%) died. After adjusting for illness severity (Acute Physiology and Chronic Health Evaluation II score) and functional status (Katz Index of Activities of Daily Living score), a body mass index (BMI)

OBJECTIVES: To determine change in albumin from hospital discharge to 3-month follow-up and the prognostic significance of persistent hypoalbuminemia in older veteran patients. DESIGN: A prospective cohort study. SETTING: A geriatric rehabilitation unit of a university-affiliated Department of Veterans Affairs hospital. PARTICIPANTS: The study population consisted of 282 subjects (of 322 randomly selected discharges who were free of cancer and terminal conditions) that completed the 90-day postdischarge assessment; most were older (75.4 ± 8.6), white (76%), and male (99%). MEASUREMENTS: Each subject completed a comprehensive discharge assessment, had a repeat albumin an average of 94 days later, and was then tracked for 5 years. The strongest predictors of survival were identified using Cox proportional hazards regression analysis. RESULTS: Between hospital discharge and the 3-month reassessment, albumins improved by more than 2 g/L in 122 subjects (43%), stayed the same in 112 subjects (40%), and deteriorated by more than 2 g/L in the rest. During followup, 190 subjects (67%) died. Of the 38 nutritional, functional, demographic, and illness severity variables evaluated, the 3-month postdischarge albumin was the strongest predictor of long-term mortality. Those with albumins less than 35 g/L had a 2.6 times greater mortality than those with albumins of 40 g/L or greater (relative risk = 2.6, 95% confidence interval = 1.8-3.8). After controlling for 3-month albumin, hospital-discharge albumin was not significantly associated with long-term mortality. CONCLUSION: In older people, a low serum albumin 3 months after hospital discharge is associated with a poor long-term prognosis. It is not known whether this represents ongoing inflammation or inadequate nutrition. [ABSTRACT FROM AUTHOR]
