[Rehabilitation and COVID disease: characterization and follow-up of hospitalized patients in Granada, Spain].

Objective: The characterization of a sample of patients hospitalized with complications of the COVID-19 infection regarding potential prognostic factors, clinical evolution, and impact of rehabilitation treatment on functional, motor, and respiratory outcomes.

Method: Descriptive, retrospective, longitudinal study of a cohort of patients under rehabilitation treatment admitted at Virgen de las Nieves University Hospital in Granada from March to June 2020, assessed upon admission, discharge and at 3 rd month using physical condition scales (IFIS) and functional assessment: general (Rankin, Barthel), respiratory (mMRC, BORG) and gait (FAC).

Results: 30 patients with a mean age of 62.8 (54-70) years were included, 80% with comorbidity: hypertension 66.7%, obesity 36.7%, diabetes 33.3%. The mean hospital stay was 45.4 days, with 86.7% requiring ICU (29.1 days) and 76.7% of them required mechanical ventilation. An 86.7% of the patients presented with complications, mostly with polyneuropathy-myopathy of the critical patient (83.3%). At discharge, 80% required walking assistance. The functionality index showed a "U"-evolution at admission, discharge and at 3 rd month (Barthel 93.8; 60.0; 91.6 respectively). A greater functional decline (Barthel < 60) was found in male patients, COPD, HT, obesity, and elevated protein C reactive at admission; and a more favourable evolution in those with elevated D-dimer and lymphocyte values upon admission. CONCLUSIóN: Hospital admission for COVID-19 patients involve complications at the functional, respiratory and gait levels that are mostly serious but partially reversible at 3 months with rehabilitation treatment. Potential prognostic factors are described and deserve prospective studies.
