Abstract
Objective: To evaluate the prediction value of RDW of patients, who were diagnosed community-acquired pneumonia (CAP), admitted to hospital. Subject and method: A cross-sectional, retrospective descriptive study at the Emergency Department - 108 Military Central Hospital from 2021-2022. The data was collected in adult patients (≥ 18 years old) diagnosed CAP were admitted to hospital. Measurement of clinical and laboratory indicators, treatment and outcomes of patients. The pneumonia severity index (PSI) and CURB-65 were accounted. We assessed the evaluation of RDW combined with two scales above in the association of 30-day mortality and admission to ICU. Result: There were 350 patients included, who were divided into two groups, which consist of: A group with RDW < 14% and others with RDW > 14%. The PSI and CURB-65 were higher in patients with a high RDW (p<0.001). RDW showed the mild level in predicting ICU admission and 30-day mortality with AUC 0.7 (p<0.001), 0.708 (p<0.001) respectively. Notably, RDW combinating with PSI and CURB-65 reveal the evaluation of ICU admission at 0.949 and 0.950 respectively and the figures for 30-day mortality were 0.990 and 0.978, respectively, which show higher capabilities in predicting adverse outcomes of the combinations between RDW with these two scores. Conclusion: RDW indicate the valuable prediction with 30-day mortality and admission to ICU in CAP patients admitting hospital. The values increase when RDW is combined with PSI and CURB-65.
