Subarachnoid hemorrhage (SAH) is a significant healthcare problem. It is estimated that 30000 Americans suffer from aneurysmal SAH each year. Delayed cerebral ischemia (DCI) is one of the major causes of morbidity and mortality after SAH, and occurs in 20–40% of patients.[
We developed and evaluated a mobile medical app for iOS (Apple Inc, Mountain View, CA) using class 1 CE-marked technology for risk minimization. The app, called SAH DCI, has been evaluated by all authors independently, where the results of the mobile clinical decision support system were compared with manually calculated scores, which were based on the original classification systems. The app provided identical results compared to manual calculation of the relevant classification systems.
The app consists of two screens, a basic module and an advanced module. The basic module asks 4 questions to calculate 3 grading scales (WFNS SAH Grade,[
In conclusion, the SAH DCI app offers clinicians a user-friendly and accurate tool for mobile clinical decision support on DCI after SAH. It combines multiple classification systems for risk calculation that may help to guide treatment, as well as ease and quicken the clinical implication of different SAH scores. Further research and comparative effectiveness studies focusing on different classification systems are needed to extract the main parameters that predict DCI after SAH.
