                        The U.S. Centers for Disease Control and Prevention (CDC) has prepared a code set for use in codingrace and ethnicity data. This code set is based on current federal standards for classifying data onrace and ethnicity  specifically the minimum race and ethnicity categories defined by the U.S. Office ofManagement and Budget (OMB) and a more detailed set of race and ethnicity categories maintainedby the U.S. Bureau of the Census (BC). The main purpose of the code set is to facilitate use of federalstandards for classifying data on race and ethnicity when these data are exchanged  stored  retrieved or analyzed in electronic form. At the same time  the code set can be applied to paper-based recordsystems to the extent that these systems are used to collect  maintain  and report data on race andethnicity in accordance with current federal standards.

                        This operation is used to return all the references to documents related to a patient. The operation takes the optional input parameters  - patient id - start date - end date - document type and returns a [Bundle](http   hl7.org fhir bundle.html) of type  searchset  containing [US Core DocumentReference Profiles](http   hl7.org fhir us core StructureDefinition us-core-documentreference) for the patient. If the server has or can create documents that are related to the patient  and that are available for the given user  the server returns the DocumentReference profiles needed to support the records. The principle intended use for this operation is to provide a provider or patient with access to their available document information. This operation is *different* from a search by patient and type and date range because  1. It is used to request a server *generate* a document based on the specified parameters. 1. If no parameters are specified  the server SHALL return a DocumentReference to the patient's most current CCD 1. If the server cannot *generate* a document based on the specified parameters  the operation will return an empty search bundle. This operation is the *same* as a FHIR RESTful search by patient type and date range because  1. References for *existing* documents that meet the requirements of the request SHOULD also be returned unless the client indicates they are only interested in 'on-demand' documents using the *on-demand* parameter.
