Post-COVID syndrome after ICU admission. Parameters related to a better physical recovery after 4 months

Abstract

Background: 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.

Methods: Prospective descriptive study of 125 patients valued by the Rehabilitation Service during hospitalization in ICU, from March 12th to December 31st, 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.

Results: 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).

Conclusions: 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.
