Comparison of Four Scoring Systems in Predicting Risk of Stroke-associated Pneumonia in Patients with Acute Ischemic Stroke / 中国康复理论与实践

ABSTRACT

@#Objective To compare the performance of Prestroke Independence, Sex, Age, National Institutes of Health Stroke Scale (ISAN) score, Age, Atrial fibrillation, Dysphagia, Sex, Stroke Severity (A2DS2) score, acute ischemic stroke-as-sociated pneumonia score (AIS-APS), and Preventive ANtibacterial THERapy in Acute Ischemic Stroke (PAN-THERIS) score in predicting the risk of stroke-associated pneumonia (SAP). Methods The baseline characteristics and laboratory data of 338 patients with ischemic stroke in emergency ward from April, 2014 to December, 2017 were retrospectively analyzed. Patients were allocated into SAP group (n=125) and non-SAP group (n=213). Receiver operating characteristic curve (ROC) was used to evaluate the predictive effect of four different scoring systems for ischemic SAP. Results Totally, 125 (37.0%) patients developed SAP. There were significant differences in age, complications (atrial fi-brillation, coronary heart disease and history of stroke), Glasgow Coma Scale (GCS) score, National Institute of Health Stroke Scale (NIHSS) score, ISAN score, A2DS2 score, AIS-APS score and PANTHERIS score between two groups (P<0.05). The A value of PANTHERIS score was 0.818, which was the lowest among four scoring systems (P<0.05). No significant difference was found in the A value between A2DS2 score and ISAN score (P>0.05). Conclusion ISAN, A2DS2 and AIS-APS scoring systems all present good discrimination and calibration in predicting the risk of ischemic SAP. The AIS-APS score calculation is relatively complex, so it is suggested that ISAN and A2DS2 scoring systems be used in emergency.
