Mechanical ventilation of patients on long-term oxygen therapy with acute exacerbations of chronic obstructive pulmonary disease : Prognosis and cost-utility analysis.
To analyze the prognosis and costs of mechanical ventilation in patients with exacerbations of chronic obstructive pulmonary disease (COPD) treated with long-term oxygen therapy.
A prospective cohort study.
Follow-up at 1 and 5 years.
Cost utility analysis.
A medical-surgical intensive care unit (ICU) in a university hospital.
20 patients with previous COPD treated with long-term oxygen therapy and needing mechanical ventilation due to acute respiratory failure.
Measurements and main results
Mortality in the ICU, in-hospital mortality (ICU plus ward), and mortality at 1 and 5 years, and factors associated with prognosis and cost-utility were assessed.
The mean Acute Physiology and Chronic Health Evaluation II score was 20 (median 20 range 12-36).
Cumulative mortality was 35% in the ICU, 50% in hospital, 75% at 1 year, and 85% at 5 years.
Factors significantly associated with mortality in the ICU were low levels of albumin (p=0.05) and sodium (p=0.01) at admission.
Patients who died in hospital and in the first year after discharge had a lower forced expiratory volume in 1 s (FEV1) than survivors (p=0.03 and p=0.05, respectively).
The cost per Quality Adjusted Life Year (QALY) was U. S. $26283 and U. S. $44602 in a « best » (cost/QALY calculated for the life expectancy in Spain) and a « worst case scenario » (cost/QALY calculated for a 68-year life expectancy), respectively. (...)
