Owing to the associated morbidity and mortality, health-care
utilization is usually significantly increased during an exacerbation.
A prospective study performed in the United States in 1995, involving
1,016 adults admitted to hospital for an exacerbation of COPD with a
Paco2 ≥ 50 mm Hg,1
found the median length of hospital stay was 9 days (range, 5 to 15
days). In this cohort, the median cost of stay was $7,100
(interquartile range, $4,100 to $16,000), and within the following 6
months, there were 754 hospital readmissions (in 446 patients).
