Long-term outcomes in critically ill patients with acute respiratory failure.

Purpose of Review: This review aims to explore the latest evidence on long-term outcomes in patients admitted to the ICU because of acute respiratory failure (ARF).
Recent Findings: As the survival rate of critically ill patients with acute respiratory failure improves, long-term mortality and disability still influence the quality of life of survivors and their caregivers. Patients admitted to the ICU because of ARF are at risk of developing the postintensive care syndrome, which presents with physical, cognitive and mental symptoms, all of which may impair their quality of life. Caregivers seem to be affected as well, which may lead to intergenerational trauma. The need for more care, including prone positioning, invasive support (e.g. mechanical ventilation, ECMO) and deep sedation are probably adjunctive risk factors for poor long-term outcomes.
Summary: There is not much data on the long-term outcomes of patients who have survived ARF. More follow-up studies should be conducted, especially in centers providing higher levels of costly care (e.g. ECMO). Randomized controlled trials on interventions for ARF should include patient-centered long-term outcomes in addition to mortality rates. The high mortality rates associated with ARF mandate collaboration among multiple centers to achieve an adequate sample size for studying the long-term outcomes of survivors.
