The OCCU app is designed to help streamline the patient referral process for doctors in Toronto and the surrounding area. The app utilizes geocoding through the Geopy library and pulls data from external Excel sources hosted on GitHub for specialties and doctor information. It allows the user to input patient addresses, select specialties, indicate provider gender preference, and set a maximum distance for doctor location. The app also features an integration with OpenAI's GPT-3.5 for generating referral notes based on the visit notes the user inputs.

Use Cases Limitations Evidence Owner's Insight
  • Healthcare providers can quickly find specialists based on patient needs and can generate drafts of referrals, reducing the time taken to create the referrals.
  • This app has the potential to improve patient care by reducing wait times for specialist consultations.
  • Regional Scope: Currently, the app can only find specialists in Toronto or the surrounding area.
  • Data Security: While OpenAI doesn’t use the data sent via the API to train/improve its models and the data is only retained for 30 days to monitor for abuse before being deleted, the OpenAI API used is not HIPAA-compliant. So, don’t enter any sensitive or identifiable information. For more information on how OpenAI handles information sent via its API, see the “API Platform FAQ” section of
  • Up-to-date Information: The app's effectiveness relies on regularly updated doctor information and specialties.

As of now, data supporting the app’s effectiveness has not been collected. The application is in the early stages of deployment. Future updates will include feedback from initial users and healthcare professionals, as well as measures of its usefulness and impact (e.g., amount of time the app saved for healthcare professionals, how long the patients wait to see a specialist).

The owners created this app with a vision to reduce administrative burdens associated with patient referrals by streamlining the process. By leveraging AI, the app also simplifies the creation of referral notes, which can be a time-consuming task. The integration of various Python libraries and external APIs demonstrates a commitment to using open-source tools and technologies to improve healthcare administration.
