The role of serum red blood cell distribution width level in predicting the short term mortality of community-acguired pneumonia, acute attack chronic pulmonary disease, and acute pulmonary thromboembolism

Background: There is a growing concern in inflammatory parameters that are commonly used routine practice and can be measured cost-effectively for predicting mortality community-acquired pneumonia (CAP), acute-attack chronic obstructive pulmonary disease (COPD), acute thromboembolism (PTE). Red blood cell distribution width (RDW) significant parameter indicating the heterogeneity of size red cells (RBCs). The present study was designed to compare RDW levels among patients were hospitalized due CAP, PTE, COPD, all which characterized by persistent inflammation, investigate role 30-day mortality.
 Materials Methods: on admission three groups evaluated retrospectively.
 Results:The 554 comprised 320 (57.76%) men 234 (42.24%) women with mean age 67.074±14.73 years. 92 (16.6%) 265 (47.8%) 197 (35.6%) COPD patients. Mean 14.42%±2.73% (range, 3.77-28%) while it 14.88%±3.30% CAP group, 13.21%±2.77% 15.15%±2.12% PTE group. In groups, significantly higher compared those without (p=0.008, p=0.020, p
