Aim: Several studies have investigated the association between biomarkers and short-term prognosis in the coronavirus infectious disease 2019 (COVID-19). However, data on the long-term prognosis are limited. To determine the predictive value of systemic immune-inflammation index (SII) and C-reactive protein (CRP) to albumin ratio (CAR) for in-hospital and 1-year outcomes during COVID-19. Material and Method: The primary outcomes were in-hospital and 1-year mortality. The secondary outcomes were the intensive care unit (ICU) need at admission and transfer to the ICU later on. Results: The study included 449 (53.6%) males and 389 (46.4%) females with a mean age of 53.8±18.5 years. Previously known heart failure (HF), COVID-19-related HF, acute renal failure (ARF), diabetes mellitus, hypertension, coronary artery disease (CAD), chronic obstructive pulmonary disease (COPD)/asthma, high CO-RADS scores (>4), low ejection fraction (EF), higher CAR and SII were associated with an increased in-hospital and 1-year mortality (p<0.05). After multivariate analysis; CAR, SII, ARF, and diabetes mellitus were independent predictors of in-hospital and 1-year mortality,whereas CAD was only an independent predictor of 1-year mortality. After ROC analysis, CAR cut-off levels of 2.54 and 2.23 predicted in-hospital and 1-year mortality, respectively (p<0.001). The SII cut-off levels of 1274 and 1191 predicted in-hospital and 1-year mortality, respectively (p<0.001). Conclusion: CAR and SII can be used as valuable prognostic indexes to predict both the short-term and long-term mortality in COVID-19.
