Abstract 【Objective】 To investigate the value of red blood cell distribution width (RDW-CV) and serum calcium ratio in patients with acute pneumonia. 【Methods】According to the prognosis, 100 patients with acute pneumonia were divided into good prognosis group (n=50) and poor prognosis group (n=50). The differences of age, gender, course of disease, symptoms, pulse rate>100 beats/min, gastrointestinal symptoms, diabetes mellitus, white blood cell count (WBC), platelet count (PLT), hemoglobin (HB), C-reactive protein (CRP), D-Dimer (D-D), RDW-CV and serum calcium ratio were compared between the two groups. Logistic regression analysis was used to identify the risk factors of poor prognosis in patients with acute pneumonia. 【Results】The pulse rate > 100 beats/min, gastrointestinal symptoms and diabetes mellitus in poor prognosis group were significantly more than those in good prognosis group (P<0.05); PLT, CRP and D-D levels in poor prognosis group were significantly higher than those in good prognosis group (P<0.05);the ratio of RDW-CV to serum calcium in poor prognosis group was significantly higher than that in good prognosis group (P<0.05); Logistic regression analysis confirmed that pulse rate>100 beats/min, gastrointestinal symptoms, diabetes mellitus, PLT ≤ 115.23×109/L, CRP≥ 82.39 mg/L, D-D≥814.68 μg/L, RDW-CV and serum calcium ratio≥6.90 were risk factors of poor prognosis in patients with acute pneumonia. 【Conclusion】For patients with acute pneumonia whose RDW/serum calcium ratio is more than or equal to 6.90, we should pay close attention to it and take corresponding treatment measures in time to improve the prognosis of patients.
