Quality of life after ICU: 1-year follow-up in patients with and without COVID.

BACKGROUND

The purpose of this study was to perform a 1-year follow-up after ICU discharge and evaluate post-intensive care syndrome (PICS) in both COVID (GroupCov) and NON COVID (GroupNCov) patients.

METHODS

All consecutive patients discharged from our Intensive Care Unit (ICU) from June to December 2022 were prospectively screened. Scheduled in-person visits were carried on 3, 6, and 12 months after ICU discharge to evaluate physical, cognitive, and mental health status using different scale evaluations (SF-36, Barthel Index, ISI score, PCL-5 score, MNA-sf score, Fatigue Severity Score, MoCA Test, HADS and GDS) by means of standardized questionnaires.

RESULTS

Eighty patients (50 GroupCov vs 30 GroupNCov) were initially included, but some patients did not attend all follow-up visits. At 1-year follow-up, 60 patients (30 COVID-19 and 30 non-COVID) completed all evaluations. Both groups showed PICS, but GroupCov had a better nutritional status, better outcomes in physical evaluations, and a better perception of Quality of Life (QoL) and mental health status, but a worse cognitive assessment in the MoCA Test. Moreover, heterogeneity analysis showed that GroupNCov patients had the same trend during follow-up, while in GroupCov different trends were observed over time, especially a worse nutritional state, often found in older patients, that was related to a longer hospital stay and worse psychophysical outcomes.

CONCLUSIONS

This study shows that PICS in SARS-COV2 patients is not always homogeneous, and that different clusters of psychophysical patterns may develop over time. Although our study was only observational, it seems from our preliminary results that performing a follow-up could be the basis for a secondary prevention and to develop new therapeutic strategies after patients discharge from ICU.
