## What is SSI RSS Calculator?

Surgical Site Infection Risk Severity Score Calculator (SSI RSS) is based on the research by Children's Spine Study Group (CSSG) and Columbia Orthopedics.

To use the app, navigate to the appropriate calculator using the tab bar at the bottom. Currently the available calculators are: Early Onset Scoliosis (EOS), Adolescent Idiopathic Scoliosis (AIS), and Cerebral Palsy (CP).

Push on the switches next to each risk factor and the SSI probability will be shown at the bottom of the page. To reset, shake the device. A Reset Dialog will appear to reset the calculator.
