Recommended Query Flow

Particle customers have the option to implement our Query API in 3 different ways, depending on preference and which platform services customers are opted into:

1. Our Data Deltas Implementation Flow [RECOMMENDED]
   1. Our Data Deltas offering leverages parsed data in FHIR and/or Flat format, de-duplication, and deltas between multiple queries for a patient. For example, if John Smith is queried on Jan 1st and July 1st, Deltas gives customers the ability to only retrieve data between Jan 1st and July 1st or any new information pulled that wasn't initially included in prior queries for the same patient.
   2. Note that the Deltas API also gives customers the ability to specify the timeframe in which you'd like to retrieve data (e.g., if you want to retrieve data for a window other than the time since the last query). Customers do additionally have the option to pull full patient history via the Deltas APIs, if desired.
   3. Please contact your Particle Account Team if you're interested in enabling this functionality on your account.
2. Our C-CDA API Implementation Flow
   1. This is for customers who only require access to the raw documents returned from the EMRs and other data sources that Particle has connections to. These are un-parsed documents in their raw form.
3. Our Legacy Implementation Flows
   1. These are older implementation methodologies that do not incorporate the data deltas functionality mentioned above. Existing customers who are already implemented on these flows can continue to leverage them as needed.
   2. If you are currently implemented on these flows and are interested in exploring other integration options, please contact your Particle Account Team for more information.
