Retrieves the N most recent Observation resources for a subject matching search criteria specified as query parameters, grouped by Observation.code, sorted from most recent to oldest. Implements the FHIR extended operation Observation-lastn (STU3, R4). DSTU2 doesn't define the Observation-lastn method, but the server supports it the same way it supports STU3. Search terms are provided as query parameters following the same pattern as the search method. The following search parameters must be provided: - subject or patient to specify a subject for the Observation. - code, category or any of the composite parameters that include code. Any other valid Observation search parameters can also be provided. This operation accepts an additional query parameter max, which specifies N, the maximum number of Observations to return from each group, with a default of 1. Searches with over 1000 results are rejected. Results are counted before grouping and limiting the results with max. To stay within the limit, constrain these searches using Observation search parameters such as _lastUpdated or date. On success, the response body contains a JSON-encoded representation of a Bundle resource of type searchset, containing the results of the operation. Errors generated by the FHIR store contain a JSON-encoded OperationOutcome resource describing the reason for the error. If the request cannot be mapped to a valid API method on a FHIR store, a generic GCP error might be returned instead.

Required Scalar Argument

  • <parent> (string)
    • Required. Name of the FHIR store to retrieve resources from.

Optional Output Flags

The method's return value a JSON encoded structure, which will be written to standard output by default.

  • -o out
    • out specifies the destination to which to write the server's result to. It will be a JSON-encoded structure. The destination may be - to indicate standard output, or a filepath that is to contain the received bytes. If unset, it defaults to standard output.
