Objective To study the sensitivity and specificity of the Chinese eating assessment tool (EAT-10) in screening acute stroke patients for oropharyngeal dysphagia (OD).Methods A total of 130 inpatients with acute stroke were screened using the Chinese EAT-10.On the same day they were also screened using the gold standard technique for diagnosing dysphasia-videofluoroscopy.A receiver operating characteristics (ROC) curve was developed to study EAT-10's sensitivity and specificity.A Youden index,positive predictive value (PPV),negative predictive value (NPV),and positive and negative likelihood ratios (LHR+ and LHR) were quantified.Results According to the ROC curve,a cut-off point of 1 (EAT-10 score≥ 1) gave the best sensitivity (77.9％),the highest NPV (73.2％),with 66.1％ specificity,71.6％ PPV,2.30 LHR+ and 0.33 LHR in screening for OD.The test-retest reliability was above 0.7.An investigator consistency reliability test showed good repeatability,and the consistency between each item and the mean total score was high.Conclusion The Chinese EAT-10 has good test-retest reliability and investigator consistency.The optimal cut-off point is 1,with good sensitivity and NPV at scores ≥ 1.The test can be recommended as a screening tool for OD in acute stroke patients.

OBJECTIVE: To study the reliability and validity of the Chinese Eating Assessment Tool (EAT-10) in evaluation of acute stroke patients with dysphagia.
 METHODS: The inpatients of stroke were assessed with Chinese EAT-10. As a golden standard for evaluation of dysphagia, videofluoroscopic swallow study (VFSS) test was used to judge the reliability and validity of EAT-10.
 RESULTS: A total of 130 qualified questionnaires were collected. The Cronbach's alpha coefficient for Chinese EAT-10 scale was 0.845. The total score of each item was related. The lowest or highest correlation coefficient for the item 2 or 3 was 0.271 or 0.772. The retest reliability was greater than 0.7, which met the requirements. According to the investigator consistency reliability test, the value collected from the investigator in the item 2 kept constant. The consistent correlation coefficient of the remaining nine items was more than 0.7. The consistency between each item and the mean score was high. The EAT-10 with the cut-off point at 1 was an optimal cut-off point. With the cut-off value of 1 (EAT-10 score ≥ 1), the sensitivity and specificity for EAT-10 was 77.9% and 66.1%, respectively. The positive predictive value (PPV) and negative value (NPV) was 71.6% and 73.2%, respectively, with 2.30 LHR+ and 0.33 LHR- for dysphagia. 
 CONCLUSION The Chinese EAT-10 has a good reliability and validity in evaluation of the acute stroke patients with dysphagia. The sensitivity and negative value are the best with the cut-off value of 1 (EAT-10 score ≥ 1). It offers a good way to discriminate dysphagia, impaired efficacy, penetrations, and aspirations in acute stroke patients.

Objective:To investigate the current situation of standardized patient programs and standardized patient educators in China, and to analyze the existing problems in the implementation.Methods:Questionnaire survey was used in this study. The questionnaire was made by Delphi method, and distributed via E-mails or through the internet to medical colleges, affiliated hospitals and general hospitals across the country. Microsoft Office Excel 2016 was used for data reduction and analysis and cartography.Results:A total of 94 medical colleges and hospitals of 27 provinces and municipalities participated in the survey, of which 43.62% had carried out standardized patient programs. The primary factor affecting the program implementation was the lack of standardized patient educators. The existing trainers were mainly clinicians or nurses, and the main way of training the educators was to send them to other universities for learning. A majority of respondents (94.68%) think it is necessary to establish and formulate a unified national certification system for standardized patient educators.Conclusion:The development of standardized patient program is unbalanced in China, and the lack of standardized patient educators has become the primary factor restricting the development. In order to make standardized patients a greater role in medical education, we should encourage different types of personnel to join in the standardized patient training team, to clarify the responsibilities of standardized patient educators, to standardize the process of trainers training, and to establish the certification system of standardized patient educators.
