[Factors predicting a short length of stay for acute exacerbations of chronic obstructive pulmonary disease].
OBJECTIVE
We intended to identify the factors predicting a short length of stay in patients with chronic obstructive pulmonary disease (COPD) and acute exacerbations in order to select those who are tributary to be admitted in a short stay unit.


METHODS
Several clinical and biochemical characteristics were compared in a group of patients with COPD admitted in a short stay unit during an acute exacerbation, classified as lasting 4 days or > 4 days of hospital stay.


RESULTS
A comorbidity index of 2 [1-2] vs 3 [2-3.5], a number of breaths per minute of 29.0 (6.5) vs 33.6 (6.8) and a pCO2 value on admission of 39.1 (5.3) vs 50.7 (12.0) mmHg were factors independently associated with a shorter stay (p < 0.001 in all).


CONCLUSIONS
Some clinical characteristics of COPD patients are predictive of a short length of stay during acute exacerbations.
