Conditional information

How this modell should be used:
The expanded CURB-65 is a simple and effective severity score for community-acquired pneumonia (CAP) patients.

Model performance:
Liu et al (2016) compared the effectiveness of different pneumonia severity scores to predict mortality. The predictive efficiency of the expanded CURB-65 was deemed better than other score systems. Moreover, the clinical usefullness of the expanded CURB-65 was confirmed in an external validation cohort of 1164 patients with pneumonia. Yet, model calibration was suboptimal in patients with health care- associated pneumonia (HCAP).
