Topic: Verify patient exists

Naminder Soorma (May 06 2016 at 08:57):

Hi, I have a requirement using RESTful where we just want to verify if a patient id exists. So it returns a True or False, I do not want to pull back the whole Patient Resource. Can anyone give an idea on the most efficient way to do this?

search and ask for _summary=count

Naminder Soorma (May 06 2016 at 09:37):

I have got it to return total number of records like this [$base]/Patient?_summary=count
But am struggling with the syntax to return just for an id so something like
[$base]/Patient/71/_summary=count

EDIT: thanks got it working with this code

[$base]/Patient?_id=71&_summary=count

Naminder Soorma (May 06 2016 at 12:03):

Can I add something to the RESTful query to return me another field as well such as patient active?

Grahame Grieve (May 06 2016 at 12:03):

see _elements

Naminder Soorma (May 06 2016 at 12:39):

Thanks Grahame worked great, here is my query for others. [base]/Patient?_id=71&birthdate=19340609&_elements=identifier,link_summary=count

Another question that has arisen, is it possible to return an extension using this method too?

Grahame Grieve (May 06 2016 at 15:03):

all or none, I guess

Brian Postlethwaite (May 07 2016 at 18:43):

and not many servers are implementing elements at the moment too.
