D-dimer Levels as Novel Biomarker Predictor for All-cause In-hospital Mortality Risk in COVID-19 Patients
Background : Coronavirus disease 2019 (COVID-19) has affected people all around the world in varying degrees of severity, causing death. The global case fatality rate (CFR) due to COVID-19 was 2.2 % as of January 1st, 2021. The CFR in the Kediri district is 7.7%, which is higher than the Nasional CFR of 3%. In COVID-19, we looked at high D-dimer as one of the predictors of in-hospital mortality. Objectives : The goal of this study was to find a link between D-dimer levels and all-cause in-hospital mortality in COVID-19 patients, as well as to define the best cut-off point. Methods : A single-center cross-sectional study was conducted. From March to December 2020, 185 COVID-19 patients treated at Kediri General Hospital who were confirmed positive by RT-PCR matched the eligibility criteria. The levels of D-dimer were divided into two groups: those above and those below the cutoff point. We The primary endpoint was all-cause in-hospital mortality. Data were collected retrospectively and processed using SPSS version 25.0. Results : significant associated with all-cause inhospital mortality (adjusted odds ratio [OR] 3.46; 95% confidence interval [CI] = 1.41 – 8.49, p = 0.007), with a sensitivity of 82.1% and a specificity of 42.2% ( area under curve [AUC] = 0.628; 95% CI = 0.527 – 0.728; p = 0.012). Conclusion : Elevated D-dimer levels were associated with all-cause in-hospital mortality. In our study, the
