Encounter Profile
This Encounter profile is part of the set of resource profiles supported by the API Server used with the athenaPractice 12.3 and athenaFlow 9.12 products. It further describes read and search capabilities of these products. Note: The create and update operations are NOT supported for this resource.
Overview
This is the recorded interaction between a patient and a healthcare provider for the purpose of receiving healthcare services or a health assessment.
Scope and Usage
This profile is used to define the content that will be returned by the API Server in response to requests to access Encounter resources. All elements listed in the differential profile view are Supported, which means that the API Server is capable of supplying these fields from the product database when they have been populated via the product or its APIs.
Source
Each physician interaction with a patient in athenaPractice or athenaFlow results in a chart document, thus the Encounter resource is derived from the DOCUMENT table in athenaPractice and athenaFlow. Specific detail can be found in the Mappings section in the profile detail page.
Supported Operations
The operations supported by this resource are listed below.
Read Operation
Read operations are executed as specified in the HL7 FHIR RESTful API implementation definition. To read a Encounter, an application shall perform an HTTP GET, specifying the identifier of the resources being retrieved.
GET [base]/fhir/Encounter/[id]{?_format=[json|xml]&_summary=[true|data]}
Read Operation Parameters
| Parameter | Description |
|---|---|
| [base] | Specifies the base URL of the FHIR Server, e.g., https://cpsapisandbox.virenceaz.com:9443/demoAPIServer |
| [id] | Specifies the identifier of the Encounter resource to retrieve |
| [_format] | Specifies the format of the output and may be xml or json. When present, the _format value overrides the value of the Accept header in the request. |
| [_summary] | Filters the output to include only summary elements (_summary=true) or to omit the generated narrative (_summary=data). Note: If the generated html narrative for the resource is not going to be used by the call, using _summary=data provides slightly improved API response times. |
Read Operation HTTP Response Codes
| Response Code | Description |
|---|---|
| 200 OK | The requested resource was found and is contained within the body of the HTTP response. |
| 401 Unauthorized | Authorization is required for this request, and either the Authorization header is missing or the supplied user credentials in the Authorization header are not valid or have expired. The body of the HTTP response will contain an OperationOutcome resource that indicates that Authorization is required. |
| 404 Not Found | The requested resource does not exist. The body of the HTTP response will contain an OperationOutcome resource that indicates that the resource could not be found. |
| 500 Server Error | The server may return other error codes to indicate other error conditions. The body of the HTTP response will contain an OperationOutcome resource that indicates the nature of the error. |
Search Operation
Search operations are executed as specified in the HL7 FHIR RESTful API implementation definition. To search for Encounter resources, an application shall perform an HTTP GET, specifying the query parameters associated with the resource.
GET [base]/fhir/Encounter?{search-parameters}{&_count=[max-results]&_format=[json|xml]&_summary=[true|text|data]}
Search Operation Parameters
| Parameter | Description |
|---|---|
| [base] | Specifies the base URL of the FHIR Server, e.g., https://cpsapisandbox.virenceaz.com:9443/demoAPIServer |
| [_count] | Specifies the maximum number of search results to return in a single query. Note: The count of results does not limit the number of additional resources returned via the _include parameter. No more than max-results Encounter resources which match the search criteria will be returned. The API Server has default and maximum limits for the value that can be specified for this parameter. These limits may vary depending upon the client application vendors participation level in the AthenaHealth Partner program. Note: The API Server support the HL7 FHIR Paging capability. |
| [_format] | Specifies the format of the output and may be xml or json. When present, the _format value overrides the value of the Accept header in the request. |
| [_summary] | Filters the output to include only narrative elements (_summary=text), summary elements (_summary=true) or to omit the generated narrative (_summary=data). Note: If the generated html narrative for the resource is not going to be used by the call, using _summary=data provides improved API response times, especially when returning larger result sets. |
| _id (token ) | The ID of the resource |
| _lastUpdated (date ) | |
| _lastUpdated-fromnow (quantity ) | Like _lastUpdated except expressed as a positive or negative offset from the current time in units of time , e.g. _lastUpdated-fromnow=ge7||d for more than seven days in the future or =le-2||mo for less than two months in the past. The unit must be specified. |
| _security (token ) | |
| appointment (reference ) | The appointment that scheduled this encounter |
| condition (reference ) | Reason the encounter takes place (resource) |
| date (date ) | A date within the period the Encounter lasted |
| date-fromnow (quantity ) | Like date except expressed as a positive or negative offset from the current time in units of time , e.g. date-fromnow=ge7||d for more than seven days in the future or =le-2||mo for less than two months in the past. The unit must be specified. |
| identifier (token ) | Identifier(s) by which this encounter is known |
| indication (reference ) | Reason the encounter takes place (resource) |
| location (reference ) | Location the encounter takes place |
| patient (reference ) | The patient present at the encounter |
| reason (token ) | Reason the encounter takes place (code) |
| status (token ) | planned | arrived | in-progress | onleave | finished | cancelled |
Search Operation HTTP Response Codes
| Response Code | Description |
|---|---|
| 200 OK | The query was performed and any results found are contained within the body of the HTTP response. Note: The search API will return 200 OK when the query itself is successful, regardless of whether or not any matching results were found. |
| 401 Unauthorized | Authorization is required for this request, and either the Authorization header is missing or the supplied user credentials in the Authorization header are not valid or have expired. The body of the HTTP response will contain an OperationOutcome resource that indicates that Authorization is required. |
| 500 Server Error | The server may return other error codes to indicate other error conditions. The body of the HTTP response will contain an OperationOutcome resource that indicates the nature of the error. |
