Predicting COVID-19 Patients' Clinical Outcomes Using ICU Mobility Scale and MRC Sum Score

The investigators hypothesize that early mobility condition and muscle power may be the predictive factors for COVID-19 patients' activity prognosis and hospitalization days. To prove our hypothesis, the investigators checked the patient's baseline ICUMS and MRCSS upon admission. Also, blood test results were also obtained. Subsequently, the investigators measured their outcomes by Barthel index and hospitalization length, and divided them into two groups. The ICUMS, MRCSS and the blood test results differences between two groups were checked. For those factors that showed significant difference between two groups, the investigators recruited them into regression model. Last, receiver operating curve of those factors were plotted to find the appropriate cutoff points for identifying two groups of outcomes.
