Patient Identifier - Search by MRN

[Daniel B]

Hi all,

I'm working through the GET /Patient functionality and would like to search for patients matching a specific MRN. It seems that the identifier search parameter is the best option for me here.

I keep getting stuck because the request will pull many patients who seem to have no relation to the identifier whatsoever.  For example, in the open playground, there is one patient with MRN 348348348.  Yet the server responds with five patients.

https://fhir-open.sandboxcernerpowerchart.com/dstu2/d075cf8b-3261-481d-97e5-ba6c48d3b41f/Patient?identifier=348348348

The other patients are not associated with the 348348348 identifier at all, but they all have "348" somewhere in their chart, for example in their phone number. 

I know I can just parse out the only patient that actually has the discrete MRN field set to 348348348, but I wanted to bring up what I found to be inconsistent behavior.

Thanks!

Dan

Dan, your findings are correct.  It's currently more of a fuzzy search, but we have more of what you expect coming in a future update.  You can check out posts here and here for some additional details.
