Conclusion: This study, while confirming the poor prognosis of FIIP patients in ICU, highlights the better prognosis of DI-ILD and M-ILD even though severity criteria on admission are similar in these 3 groups. These data impact on the management of these patients in ICU in whom a proper diagnostic of the underlying condition is crucial.
