Release Notes

Week of December 16, 2024

🚀 What's New

A Discharge Summary API that enables customers to retrieve the file_id and resource_id for any discharge summaries identified for a patient. These IDs can subsequently be leveraged to download the actual discharge summary files from Particle.
Patient Search in the UI is no longer case sensitive meaning that users no longer have to exactly match patient demographics submitted at the time of querying to find a specific patient.
Clinical notes are easier to read in the UI by implementing breaks in the text that differentiates notes from different providers.

Week of December 9, 2024

🚀 What's New

Implemented date range-based querying to ensure Particle is not retrieving less data than available from implementers who apply a default time range(e.g. six months) if none is provided. We pass in date ranges to ensure that complete historical data is retrieved.

Week of June 3, 2024

⌛Coming Soon

Updates to the retrieved document file names! The file name convention that Particle currently follows is Type_FacilityName_Date.xml. In the next few weeks, Particle will be updating the file name convention to be Type_FacilityName_Date_UUID.xmle.g., Medical_Summary_Provider_LLC_2022-11-08T000000Z_3ae7fa2a-0bd5-4622-9d19-932a08f4a3b2.xml. By appending the UUID to the file name as the last segment before the extension, Particle is intending to address duplicate file names so that customers are able to distinguish between different files for the same patient. This file name convention update will also be reflected in Particle's Sandbox environment! Please make the appropriate plans to ensure that you do not experience any breaking changes with this update, especially if you are expecting or parsing specific fields within the file name.
