The mobile application will be developed by a team at Penn State Hershey from the results obtained in a systematic literature review and quality assessment of clinical practice guidelines for topical corticosteroid use. The quality of the guidelines will be assessed using the AGREE II tool. After the app user enters in information concerning patients' rash location and desired treatment duration, the app will generate a list of recommended topical steroids (focusing on specific quantity and potency) for the patient's particular area of need. It is ultimately up to the physician whether or not to follow or modify the recommended suggestions.
