Model of Kim et al for Predicting Bacteremia in a Patient with Community-Acquired Pneumonia (CAP)

Description

Kim et al reported a simple model for predicting bacteremia in a patient with community-acquired pneumonia (CAP). This is based on a subset of variables used in the prediction model of Lee et al. The authors are from multiple institutions in South Korea.


Patient selection: community-acquired pneumonia (CAP)

 

Parameters:

(1) platelet count in 10^9/L

(2) serum albumin in g/dL

(3) serum CRP in mg/dL
