WebIShock, was calculated using the formula: HR/TAS, IShockM was calculated using HR/TAM, and IShock adjusted for age was calculated using the formula IShock x age. These indices were analyzed using the ROC curve and the Youden index to find the value that predicted in-hospital mortality with the greatest sensitivity and specificity. WebThe prognostic performance of age SI for prediction of PIH was better than MSI and SI (p = 0.006 for age SI versus MSI, p = 0.005 for age SI versus SI). Conclusions: Preintubation age SI, MSI, and SI are all independent predictors of …
