その他関連情報/Other related information | Assessment and Data Collection
All patient assessments will be made by residents supervised by staff physicians or attending emergency physicians. Physicians will be oriented to the study and instructed to input clinical and laboratory findings at the time of assessment into data collection software specially developed on a smartphone, or onto electronic charts of a hospital that shows the same data items as the smartphone device. Electronic chart data will be later transferred to the smartphone device manually. Data management All patient data will be anonymized before being uploaded to the internet server via direct smartphone connection or from personal computers at emergency centers with Bluetooth connections to smartphone devices. Collected anonymized data will be monitored and cleaned by the Joint Center for Researchers, Associates and Clinicians (JCRAC), an authorized center for quality management of data. The final data set for analyses will be provided by JCRAC. According to the methodological standards*, we will conduct univariate analyses (2-sided t test for continuous variables and Fisher’s exact test for categorical variables) for the strength of association between each possible predictor variable and the outcome variables, and for selections of possible predictors. We will use multivariate, recursive partitioning analysis to develop the clinical decision rules using those possible predictors and the outcome. Sensitivity and specificity will be estimated for each rule. A clinical decision rule for a life-threatening event like SAH requires 100% sensitivity with a narrow confidence interval. *Stiell IG,Wells GA.Methodologic standards for the development of clinical decision rules in emergency medicine. Ann Emerg Med.1999;33(4):437-447. |
