Yan et al reported the ICH-LR2S2 score for predicting the risk of stroke-associated pneumonia in a patient with spontaneous intracerebral hemorrhage. The authors are from Beijing Tiantan Hospital, Capital Medical University, Fudan University, Charles Sturt University, and the China National Clinical Research Center for Neurological Diseases.
Patient selection: > 18 years old, spontaneous intracerebral hemorrhage
Parameters:
(1) age in years
(2) modified Ranking Scale (mRS), integer from 0 to 5
(3) fasting blood glucose in mmol/L
(4) NIHSS score
(5) Glasgow coma scale (GCS)
(6) serum C-reactive protein (CRP) in mg/L
(7) dysphagia
(8) COPD
(9) current smoking
