SAH DCI

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.
