6 McGill University Health Centre, Division of Radiation Oncology, 1001 boul Décarie- Montreal, Canada Purpose or Objective Providing patients with access to their medical records and collecting patient-reported outcomes (PROs) from them is of interest in modern healthcare. In Radiation Oncology, no major successes have been reported and the provision of medical data to patients remains a challenge. With a patient who is also a computer scientist, a radiation oncologist and a medical physicist on our team, we set out to build Opal, a mobile phone app and portal for oncology patients. Opal will provide patients with: • Appointment schedules • Check-in/call-in for waiting room management • Status of treatment planning/treatment schedule • Access to personal health information (PHI)— treatment plan, lab results, medical notes • Just-in-time educational material, specific to the patient’s diagnosis, treatment and phase of treatment Contact information and a messaging system Tools to complete PRO questionnaires Maps and hospital information (eg parking) Patient's committee module— Patients for Patients Material and Methods We developed a secure and confidential communication system that incorporates data from our Aria database (Varian Medical Systems, Palo Alto, CA), patient authentication, encrypted data exchange and a cloud server (Firebase by Google Inc.) external to the hospital. Figure 1 provides a schematic of the data flow from Aria to/from Opal. • • •

Conclusion The effect of an air pocket in the bladder during bladder hyperthermia treatment varies strongly between patients, and no relation was visible between effect size and air volume. Generally, this leads to lower temperatures in the bladder, potentially affecting treatment quality, and suggesting that care need be taken to minimise the size of air pockets during hyperthermia treatments.

Figure 1. Data flow for Opal. Firebase is a real-time cloud database by Google. Results The design, development and debugging of Opal have been guided in five ways: (1) a literature review to study existing patient portals, (2) a patient survey, (3) a patient focus group, (4) a closed beta-release to non-patient volunteers, and (5) a pilot to engaged patients who will provide feedback. Figure 2 provides screenshots of the app that will be released to our pilot group of patients.
