BACKGROUND: Prediction of severity of Post-COVID-19 condition is not clear. We determined whether hospital course variables correlated with objective and subjective outcomes 3- and 6-months post-COVID-19 onset.METHODS: Adults admitted to hospital with acute COVID-19 were recruited (Feb 15, 2020-April 1, 2021) from two tertiary hospitals in Vancouver, Canada. We recorded baseline characteristics, COVID severity score, organ function, ICU and hospital length of stay. Survivors were evaluated at 3- and 6-months post- COVID-19 onset: subjective: University of California San Diego Shortness of Breath Score, EuroQol 5D Visual Analogue Scale, Frailty Index; Objective: functional capacity (6-minute walk test), pulmonary (pulmonary function tests), cardiac (echocardiography, BNP), renal (creatinine), hepatic (AST, ALT, bilirubin), and coagulation (aPTT, INR, D-dimers, fibrinogen). RESULTS: In 133 post-COVID-19 patients (age 62 ± 14 years, 65% male with frequent comorbidities [hypertension (42%), diabetes (29%), chronic cardiac (22%)), 42% were admitted to Intensive Care Unit: 23%, 23% and 2% required ventilation, vasopressors or renal support, respectively. One-third had restrictive lung function (<80% predicted FVC %, TLC%, or DLCO%) at 3 months. Novel findings were correlations of (1) acute hepatic dysfunction with restrictive lung function at 3 months post COVID-19 onset; (2) more severe acute COVID-19 with later pro-thrombotic phenotype and (3) greater acute organ dysfunction with later objective organ dysfunction at 3- and 6-months. No hospital course variables were associated with subjective outcomes at 3- and 6-months. CONCLUSIONS: Early organ dysfunction predicts later objective pathology especially restrictive lung disease and a pro-coagulant state. These hypothesis-generating findings require further validation in additional patients.
