[Post-covid syndrome after icu admission. Parameters related to a better physical recovery after 4 months.]

Post-COVID syndrome can impact against every sphere of daily live. The objective of this work was to detect the factors correlated with a better or worse physical recovery four months after hospital discharge from a hospitalization in ICU due to COVID-19.

Prospective descriptive study of 125 patients valued by the Rehabilitation Service during hospitalization in ICU, from March 12^th to December 31^st, 2020. Data from 76 patients was analysed with clinical follow up after 1, 2 and 4 months of hospital discharge. Variables on personal, hospitalary, functional symptoms/signals and physical recovery were analysed with mean ± standard deviation, counting (percentage), T-student test and Fisher test.

After one month, fatigue was observed in 60 (80%) patients and dyspnoea in 47 (62%). After two months, fatigue in 37 (55%), dyspnoea in 25 (33%), shoulder pain in 33 (43%), average QuickDASH was 22.7 (11.3-50), Sit-to-Stand Test in 30 seconds 11.5 (10-13) and 6-minute walk test 390 meters (326-445). In the fourth month, 25 (53%) had returned to work and had an average of the physical recovery of 79.1%±18.3%. There was no correlation between physical recovery ≥75% and the first month data, but there certainly was a correlation between some second month variables, such as fatigue (p=0.001), dyspnoea (p=0.035), QuickDASH (p=0.001) and 6-minute walk test (p=0.021).

Symptoms (fatigue and dyspnoea) and functional scales (QuickDASH and 6-minute walk test) after 2 months predict a better/worsen physical recovery after 4 months of hospital discharge.
