Both sites involved have used OBERD to collect outcomes for the past three years. They have shown the ability to follow patients for many years after surgery using this system. Both sites will have patients complete the PROs on iPads while waiting to be seen before clinical visits to the surgeons. For patients who are unable to come in for clinical visits, OBERD has the capability of sending reminders via email to patients who have not filled their PROs out at the correct follow up time. If both of these strategies fail, then the patients will be contacted on every phone number available in order to achieve maximum follow-up.
