The GTI will give investigators the first sensitive tool to use in randomized trials to measure whether a reduction in steroids leads to less steroid toxicity. Right now, they are beginning to use the GTI in several clinical trials. To help clinical investigators and eventually physicians in clinical practice, the GTI team is looking to develop an app so that the instrument is accessible on a mobile platform. They are also developing a pediatric version of the GTI, since steroid side effects are different in young patients. A future app may allow patients to report their own adverse events.
