Validation of a severity grading score (SGS) system for predicting the course of disease and mortality in patients with Crimean-Congo hemorrhagic fever (CCHF)

We aimed to validate a severity grading score (SGS) system for predicting the course of disease and fatality in Crimean-Congo hemorrhagic fever (CCHF). This SGS was established using several variables that were assumed to be associated with mortality and had clinical importance. We included patients diagnosed with CCHF from different centers. Patients who had symptoms of CCHF for 9 points at admission were 96, 100, 97, 100, and 44 %, respectively. This SGS system may help appropriate the triage of patients, decrease the cost of treatment, and improve the functionality of healthcare staff. The present study is the first investigation about the validation of an SGS system in patients with CCHF.
