Predictors of 6-month mortality in elderly patients with mild chronic obstructive pulmonary disease discharged from a medical ward after acute nonacidotic exacerbation.
J Am Geriatr Soc 2008; 56(5):909-13JA

Abstract

OBJECTIVES

To identify clinical outcomes and variables associated with 6-month mortality in very elderly patients admitted for nonacidotic acute exacerbation of chronic obstructive pulmonary disease (AECOPD).

DESIGN

Prospective cohort study.

SETTING

General medicine acute care ward.

PARTICIPANTS

Two hundred forty-four elderly patients with COPD (mean age+/-standard deviation 82+/-7, 55.7% female) admitted to the hospital because of non-acidotic AECOPD.

MEASUREMENTS

Cognitive and mood status and physiological variables were measured. Self-reported comorbidities were assessed using the Charlson Comorbidity Index. In-hospital and long-term mortality and clinical outcomes were recorded.

RESULTS

At admission, this elderly population with AECOPD had low cognitive performance (mean Mini-Mental State Examination score 21+/-5), no presence of significant depressive symptoms (Geriatric Depression Scale score 4+/-3), good nutritional status (body mass index (BMI) 25.1+/-5.5), moderate comorbidity (Charlson Comorbidity Index 4.0+/-1.9), high functional disability (Barthel Index (BI) 52+/-34), and moderate severity of acute exacerbation (Acute Physiology and Chronic Health Evaluation (APACHE) II score 9.7+/-4.2). Two hundred twenty-five inpatients with AECOPD were successfully discharged, whereas 15 were transferred to the intensive care unit, and four died in the hospital. The 6-month cumulative mortality rate in discharged patients with AECOPD was 20%. Multivariate Cox analysis shows that lower BMI (beta=-0.16; 95% confidence interval (CI)=0.73-0.99), higher APACHE II score (beta=0,17; 95% CI=1.03-1.36), and lower BI at discharge (beta=-0.02; 95% CI=0.96-0.99) were independently associated with 6-month mortality.

CONCLUSION

Malnutrition, severity of exacerbation and disability status could be identified as risk factors associated with 6-month mortality of elderly patients admitted for nonacidotic AECOPD.
