INTRODUCTION
Stroke is recognized as the third cause of mortality after cardiovascular and cancer diseases, so that lead to death of about 5 million people, annually. There are several scales to early prediction of at risk patients and decreasing the rate of mortality by transferring them to the stroke center. In the present study, the accuracy of Cincinnati pre-hospital stroke scale was assessed.
METHODS
This was a retrospective cross-sectional study done to assess accuracy of Cincinnati scale in prediction of stroke probability in patients referred to the emergency department of Poursina Hospital, Rasht, Iran, 2013 with neurologic symptoms. Three criteria of Cincinnati scale including facial droop, dysarthria, and upper extremity weakness as well as the final diagnosis of patients were gathered. Sensitivity, specificity, predictive values, and likelihood ratios of Cincinnati scale were calculated using SPSS version 20.
RESULTS
448 patients were assessed. The agreement rate of Cincinnati scale and final diagnosis was 0.483 ± 0.055 (p<0.0001). The sensitivity of 93.19% (95% Cl: 90.11-95.54), specificity of 51.85% (95% Cl: 40.47-63.10), positive predictive value of 89.76% (95% Cl: 86.27-92.62), negative predictive value of 62.69% (95% Cl: 55.52-72.45), positive likelihood ratio of 1.94% (95% Cl: 1.54-2.43), and negative likelihood ratio of 0.13% (95% Cl: 0.09-0.20) were calculated.
CONCLUSION
It seems that pre-hospital Cincinnati scale can be an appropriate screening tool in prediction of stroke in patients with acute neurologic syndromes.
引言
中风被认为是仅次于心血管疾病和癌症的第三大死因，每年导致约500万人死亡。有多种量表可用于早期预测高危患者，并通过将他们转运至中风中心来降低死亡率。在本研究中，评估了辛辛那提院前中风量表的准确性。
方法
这是一项回顾性横断面研究，旨在评估辛辛那提量表对2013年转诊至伊朗拉什特布尔西纳医院急诊科且有神经症状患者中风概率预测的准确性。收集了辛辛那提量表的三个标准，包括面部下垂、构音障碍和上肢无力以及患者的最终诊断结果。使用SPSS 20版计算辛辛那提量表的敏感性、特异性、预测值和似然比。
结果
共评估了448例患者。辛辛那提量表与最终诊断的一致率为0.483±0.055（p<0.0001）。计算得出敏感性为93.19%（95%可信区间：90.11 - 95.54），特异性为51.85%（95%可信区间：40.47 - 63.10），阳性预测值为89.76%（95%可信区间：86.27 - 92.62），阴性预测值为62.69%（95%可信区间：55.52 - 72.45），阳性似然比为1.94%（95%可信区间：1.54 - 2.43），阴性似然比为0.13%（95%可信区间：0.09 - 0.20）。
结论
院前辛辛那提量表似乎可以作为预测急性神经综合征患者中风的一种合适的筛查工具。
