Xiao et al reported a score for predicting hospitalization for an adult with diarrhea. The authors are from Capital Medical University and Beijing Shijingshan Hospital in Beijing.
Patient selection: age >= 14 years with acute diarrhea
Parameters:
(1) age in years
(2) body temperature in °C
(3) mean arterial pressure (MAP) in mm Hg
(4) WBC count in 10^9/L
(5) fecal leukocytes per high power field
