Question normal

Every day many outpatient invasive and non-invasive procedures (Colonoscopy, CT and MRI scans, etc.) get cancelled for many patient related reasons. Each wasted time slot costs thousands of dollars and have a huge financial burden on the healthcare provider.
My idea is to design a software (a smartphone app) with different pre-defined profiles for different diseases and procedures to automatically inform and update patients prior to their appointment based on their feedback. Several reminders, procedure factsheet, associated risks, post-procedure considerations, need for informed consent, necessary diet. Patient will be required to comply by pressing a button. Above all, patient has the option to cancel the appointment just by pressing a Cancel button without the hassle of calling and explaining.
This reduces the manpower needed to make necessary arrangements prior to the appointment and also gives the healthcare provider the chance to work in other patients in case of a cancellation
