Sleep quality in survivors of critical illness: practical shortcomings unresolved

To the Editor,
We read with great interest the manuscript of Alexopoulou et al.  in which the authors assessed sleep-disordered breathing (SDB) as well as sleep architecture in survivors of critical illness at 10 days and 6 months after hospital discharge. Also, the authors aimed to examine whether or not sleep abnormalities influenced the patients’ quality of life. All of their patients received mechanical ventilation in the ICU, the majority of them (75%) because of acute respiratory distress syndrome (ARDS). Their results showed that in survivors of critical illness without hypercapnia and hypoxemia, sleep quality at 10-day post-hospital discharge was poor and was characterized by severe disruption of sleep architecture and excessive SDB mainly of the obstructive type. At 6-month post-hospital discharge, sleep quality remained relatively poor, however significantly better than at 10-day post-hospitalization. The quality of life was poor at 10 days and remained poorer than normal...
