BACKGROUND: Acute respiratory distress syndrome (ARDS) survivors are affected with long- term physical/mental impairments, with improvements limited mostly to the first year after inten- sive care (ICU) discharge. Furthermore, caregivers of ICU patients exhibit psychological problems after family-member recovery. We evaluated the long-term physical and mental recovery of ARDS survivors treated with veno-venous extracorporeal membrane oxygenation (VV-ECMO), and the long-term psychological impact on their caregivers.

METHODS: Single-center prospective evaluation of a retrospective cohort of 75 ARDS patients treated with VV-ECMO during a seven-year period (25.10.2009-11.08.2016). Primary outcomes were the 36-Item Short-Form Health-Survey (SF-36, patients only), and risks of depression, anxiety or post-traumatic stress disorder (PTSD), both for patients and their caregivers. We investigated correlations between outcomes and population characteristics.

RESULTS: Of 50 ICU-survivors, seven died later and five were not contactable. Among 38 living patients, 33 participated (87%, 31 with their caregiver) with 2.7 years of median follow-up. Physi- cal and mental SF-36 component scores were 42 (inter-quartile range, IQR:22) and 52 (IQR:18.5), respectively. The worst domains of the SF-36 were physical-role limitations (25, IQR:100) and general-health perception (56, IQR:42.5). Psychological tests highlighted high risk of depression (39%-42%, patients; 39%-52%, caregivers), anxiety (42%, patients; 39%, caregivers), and PTSD (47%, patients; 61%, caregivers). Patient depression or anxiety scores were correlated to age and to the outcome reported by caregivers.

CONCLUSIONS: At almost three-year follow-up, ARDS survivors treated with VV-ECMO showed reduced health-related quality-of-life and high risk of psychological impairment, in particu- lar PTSD. Caregivers of this population were at high psychological risk as well.
