Outcome of patients with idiopathic pulmonary fibrosis admitted to the ICU for respiratory failure.
OBJECTIVE
To analyze the outcome of acute respiratory failure (ARF) in patients with idiopathic pulmonary fibrosis (IPF), and to evaluate the benefits of invasive and noninvasive mechanical ventilation (MV).


METHODS
Retrospective study.


METHODS
University hospital.


METHODS
Fifteen consecutive patients with IPF referred to the ICU for ARF between January 1989 and June 1998.


RESULTS
Fifteen patients (mean +/- SD age, 64 +/- 10 years) were included. Eight patients had clinical, functional, and radiologic features of IPF, and the remaining seven patients also had biopsy specimen-proven IPF. The mean duration between diagnosis of IPF and admission to the ICU was 26.5 +/- 28 months. At the time of ICU admission, mean arterial blood gas levels were as follows: PaO(2)/fraction of inspired oxygen, 113 +/- 95; pH, 7.32 +/- 0.10; and PaCO(2), 55 +/- 21 mm Hg. All patients received MV; 12 patients required tracheal intubation, either at the time of ICU admission (n = 10) or after failure of noninvasive ventilation (NIV; n = 2); and 3 patients only received NIV. Three of the five patients receiving NIV died of respiratory failure. Eleven patients died in the ICU, either from hypoxemia (n = 8) or from septic shock (n = 3). Four patients were discharged alive from the ICU, and two of them died shortly thereafter.


CONCLUSIONS
The outcome of patients with IPF referred to the ICU for ARF was very poor and not improved by MV. Without a clearly identified reversible cause of ARF, these patients should not benefit from admission to the ICU.
