Severe sepsis was diagnosed using Drenmsizov criteria (Chest 2006;129;968-978). 4,137 patients were included: 1,171(28.3%) without sepsis, 1,394(33.7%) with non severe sepsis and 1,572 (38%) with severe sepsis: 521(33.1%) of these had early (≥48 hours) and 1,051 (62%) late onset. There were no gender differences in early vs. late sepsis. Early sepsis was associated to elderly patients (≥65 years: 72.2% vs. 65.2%, p=0.006). Statistical differences in clinical presentation and comorbid conditions are depicted in Table 1. Early severe sepsis showed higher CURB65 scores than late sepsis (49.6% of patients vs. 41.5% with score 3).View this table:CAP with severe sepsis characteristicsConclusions: Early severe sepsis in CAP presents with greater severity while late onset does with large radiographic involvement. Diabetics, elderly patients and those with cerebrovascular disease are more prone to develop rapid onset severe sepsis in CAP.
