Patients who provide informed consent will immediately be asked to complete a brief baseline survey about their preferences for receiving prompts, either via email or via cell phone using a text message. After survey administration, all patients will be registered in the mobile health app, which will be used provide discharge care instructions and monitor their progress upon discharge. Study participants will then be randomized into one of two arms: 1) active prompts to use the study app or 2) use of study app, but no prompts. All participants will be followed for a minimum of 30 days and will be asked to complete a follow-up survey during a scheduled in-clinic appointment at the end of the study.
