FHIR Bulk Data (a.k.a. Flat FHIR)

Naming things is hard.  Sometimes technologies are given more than one name.  Such is the case with FHIR Bulk Data.  This article is written to explain FHIR Bulk Data at a high level and why it is sometimes called "Flat FHIR".

The FHIR Bulk Data is a draft specification for accessing (you guessed it) FHIR data in bulk.  Unlike regular FHIR, Bulk Data is an asynchronous exchange built atop HTTP.  Some situations where this paradigm may be useful include:
When results are very large such as population-level queries.When results are not immediately available and need to be compiled.  HTTP servers and clients usually time out in a minute or two, so any query taking longer than thirty seconds should consider this asynchronous approach.
FHIR Bulk Data responses can represent a population and can therefore be very large. After the initial request is made, an immediate response is returned to the client including the target URL in the response body. The target URL is where the final…

Why Transparent Health Was Created

Over the past few years, I've begun or contributed to a number of open source projects.  These have mostly been centered around health technology while supporting the Unites States federal government agencies such as CMSHHS, and NIST.

TransparentHealth.org and https://github.com/TransparentHealth were first created as a place to consolidate these open source projects into one place.  Other people seemed to like the idea.  Not only is open source software a good idea, but so is the adoption of open standards.  We made facilitating the adoption of standards a priority as well.

To ensure the long term maintenance of these projects and goals it became increasingly apparent that software foundation was needed.


Hence Transparent Health was created. In April of 2018, Transparent health became a non-profit organization.  The directors of the organization are Mark Scrimshire, and myself.  Other people are helping out too. We are just getting started!

We encourage your code contribution to…

Transparent Health: A Non-profit Organization

Transparent Health received tax exempt status from the IRS making it a 501(c)3 non-profit organization. We look forward to expanding our role as custodians of open source projects that benefit health care consumers.

A Punchlist for Consumer Directed Exchange Success

Health data fluidity in the United States still has a way to go to get to an ideal state. Federal efforts, such as Meaningful Use, have improved the situation somewhat, but people still struggle to access their own health information. An effort to empower patients by giving them the power to move data around on their own is gaining momentum and attention. Although it can go by many names, its often referred to as "Consumer Directed Exchange".
To clear up some ambiguity, "Directed Exchange" in US health care most often refers to theDirect Project.Direct is an encrypted email-based point-to-point exchange mechanism thatis requiredto meet Meaningful Use criteria. Direct is often used for provider-to-provider and system-to-system communication. Direct has seen little adoption by consumers (i.e. patients). 
 The term "Consumer Directed Exchange",on the other hand, is a technology agnostic term that can refer to many things.Consumer Directed Exchange can include …
