Hospital and long-term outcomes of ICU-treated severe community- and hospital-acquired, and ventilator-associated pneumonia patients

Background Our purpose was to analyse the association of pneumonia types with hospital and long‐term outcomes of intensive care unit (ICU)‐treated pneumonia patients. Methods The occurrence of pneumonia was retrospectively evaluated among prospectively registered patients admitted into a mixed university‐level ICU during a 14‐month period. Their age, severity of underlying disease, malignancy, immunosuppressive therapy and organ dysfunctions were recorded, as well as the length of hospital stay and short‐ and long‐term mortalities. Results There were 117 severe community‐acquired pneumonia (SCAP), 66 hospital‐acquired pneumonia (HAP) and 25 ventilator‐associated pneumonia (VAP) cases among the 817 patients admitted. ICU and hospital mortality did not differ between pneumonia groups. VAP and HAP patients had more malignant underlying diseases than SCAP patients (P 0.90). The patients with VAP had higher Sequential Organ Failure Assessment maximum scores compared with patients with SCAP and HAP (P
