Abstract

Objectives: To examine the prevalence of insomnia and its relationship to health-related quality of life (HRQOL) post-intensive care unit (ICU). Background: The burden of post-ICU insomnia is unknown. Methods: This cross-sectional study examined data from 120 patients with an ICU stay >24h. Pre-hospital health was assessed in-hospital. Insomnia, HRQOL and post-ICU psychiatric symptoms were assessed at 12 months post-ICU. Results: Over one-quarter (28%) of subjects met insomnia criteria at 12 months post-ICU. Post-ICU insomnia was independently associated with worse mental HRQOL (P<0.01), as well as worse scores on the HRQOL sub-domains of bodily pain (P<0.001), vitality (P<0.05) and physical function (P<0.05). However, these associations were no longer significant after adjusting for post-ICU psychiatric symptoms (P=0.33). Conclusions: Insomnia is common among ICU survivors. Post-ICU insomnia is significantly associated with mental HRQOL and could identify ICU survivors who may benefit from further psychiatric evaluation.
