SAH DCI calculates the risk for delayed cerebral ischemia (DCI) after subarachnoid hemorrhage (SAH) based on several classification systems that are published in scientific journals.
The basic module calculates 3 parameters. It uses the WFNS SAH score and the modified Fisher score to calculate the VASOGRADE risk category.[1,2]
The advanced module calculates 7 parameters. It uses some more input parameters and also calculates the BEHAVIOR score and the risk chart category as published by De Rooij et al.[3,4] In both modules, a report can be sent by email that includes all user-entered parameters and a full report as displayed in the app.
This app has been developed and tested by a neurosurgeon, and incorporates CE-marked technology for risk minimization inspired by the European MEDDEV guidelines and FDA guidance on mobile medical applications.
SAH DCI can be downloaded from the App Store.
