Operation-encounter-everything

This operation is used to return all the information related to an encounter described in the resource on which this operation is invoked. The response is a bundle of type "searchset". At a minimum, the encounter resource itself is returned, along with any other resources that the server has available for the given encounter for the user. The server also returns whatever resources are needed to support the records - e.g. linked practitioners, locations, organizations etc. The principle intended use for this operation is to provide a patient with access to their record, or to allow a client to retrieve everything for an encounter for efficient display). The server SHOULD return all resources that it has that are in the encounter compartment for the identified encounter, and any resource referenced from those, including binaries and attachments. In the US Realm, at a mimimum, the resources returned SHALL include all the data covered by the meaningful use common data elements (see DAF for further guidance). Other applicable implementation guides may make additional rules about the information that is returned. Note that for many resources, the exact nature of the link to encounter can be ambiguous (e.g. for a DiagnosticReport, is it the encounter when it was initiated, or when it was reported?)

The key differences between this operation and simply searching the encounter compartment are: * unless the client requests otherwise, the server returns the entire result set in a single bundle (rather than using paging) * the server is responsible for determining what resources to return as included resources (rather than the client specifying which ones)
