A total of 208 patients were collected from August 20, to October 5, 2020. Among these, 37 were died and 20 did not attend second outpatient clinic visit, leaving 151 for analysis. Of these, 87(58%) had complete recovery and 64(42%) had partial recovery with persistent or new symptoms. The majority of patients with complete recovery had mild-moderate pneumonia (95%), while the majority of patients with partial recovery had severe pneumonia requiring hospital admission (73%). The most common post-acute COVID-19 pneumonia persistent or new symptoms was shortness of breath(70%), followed by fatigue(53%),cough(11%),dizziness(8%), smell loss(6%),palpitation(6%), gastrointestinal tract disturbances(3%) and others, including chest pain(1.5%), and tinnitus(1.5%).(Table 1)
Mild lung injury [1.1(1-1.3), P=.012] at CT examination and high PMV [0.2(0.1-0.9),P=.027] were predictors for complete recovery.(Table 2)
Low Hb at presentation[0.5(0.3-0.8),P<.000], length of ICU stay[1(0.4-1.8),P=.014], extensive lung injury[1.1(1-1.2),P=.002], old age[0.9(0.8-1.2),P=.002] and shortness of breath at presentation [0.6(0.5-6),P=.020]were predictors for persistent shortness of breath, while high Hb[1.6(1-2.6),P=.036] ,extensive lung injury[1 (1-1.2),P=.004], and productive cough at presentation[2 (0.9-6),P=.042] were predictors for persistent fatigue.
