title: One-year mortality in elderly stable patients with COPD.
abstract: A retrospective study was performed to evaluate the risks of one-year mortality in very old hospitalized patients including those suffering from chronic obstructive pulmonary disease (COPD). Six hundred and fifty-eight disabled patients (M = 194, mean age 79.2 +/- 7.4 years) consecutively admitted to and discharged from a Geriatric Evaluation and Rehabilitation Unit (GERU) after a comprehensive rehabilitation program were studied and divided into two groups: COPD (n = 337, 51%) and non-COPD (n = 321, 49%). Multidimensional evaluation including information on demographics, cognitive status [Mini Mental State Examination (MMSE)], physical health [number of diseases, Greenfield's Individual Disease Severity (IDS), and number of drugs used], functional disability [Basic Activity of Daily Living (BADL), Tinetti scale, and Physical Performance Test (PPT)], and nutritional status [Prognostic Nutritional Index (PNI)] were assessed at admission. Survival rate was assessed over a 1-year period following discharge. COPD patients mainly differed from non-COPD in terms of older age, smoking habit, number of associated diseases and drugs used. Aggregating the IDS 2-3-4 COPD classes (symptoms + functional impairment), the risk of one-year mortality was double that of the IDS 1 COPD class (symptoms only) and of non-COPD subjects (IDS 0 class) after adjusting for age, sex, disability, malnutrition, and comorbility. Moreover, IDS 2-3-4 COPD patients suffering from cor pulmonale (CP) had a fourfold 1-year risk of mortality in comparison with the IDS 1 COPD group after adjusting for the same covariates. Hospitalized stable very old COPD patients presenting functional impairment have a higher 1-year risk of mortality than only symptomatic COPD or non-COPD subjects. The presence of cor pulmonale with COPD further increases this risk.
