NASCIS is a calculator for the NASCIS II/III protocol that may be considered in the acute treatment phase for patients with traumatic spinal cord injury. The app provides a dose suggestion based on posttraumatic interval and body weight according to scientific evaluations.

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.

NASCIS was rejected twice for the App Store for this reason:

“Apps that calculate medicinal dosages must be submitted by the manufacturer of those medications or recognized institutions such as hospitals, insurance companies, and universities”

I decided not to try any further…. therefore, the source code of the app is available for everyone who likes to compile the app for personal use, or for learning purposes.

Source code

You can download the source code from GitHub.


The app has been developed in Xcode 6.3 for iOS8 using Swift as a programming language.
