Get a list of observations

/Observation
Retrieves a list of labatory, vital sign, and alcohol or tobacco use observations that meet supplied query parameters.
Note:
- Currently, the
commentsfield may have RTF or other formatted data rather than simple text. A resolution for this issue is planned with an R4 release. - When multiple pages of observation results are returned for a single query:
- All social history observations (if any qualify for the query) are returned on the first page of results. The next item on this list does not apply to social history observations.
- Results are sorted by effective date and time in descending order. In other words, all observations on any given page of results are newer than all observations on the next page of results. Sort order within pages is not guaranteed.
- If the query uses the
_lastUpdatedquery parameter, results are sorted by last updated date and time in descending order by page, not by effective date and time.
- Oracle recommends searching by
code,date, or both.
Request
Query Parameters
-
_count: string
The maximum number of results to return per page. Defaults to 50 and maximum 200 observations can be returned
-
_lastUpdated: string
The date range when the observation was last updated.
- May be provided up to two times, and must use the
eq,ge,gt,le, orltprefixes. - When a value is provided without a prefix, an implied
eqprefix is used. - When provided twice, the lower value must have a
georgtprefix and the higher value must have anleorltprefix. - May not be provided with
date. - Only qualifies clinically significant updates such as changes to the value or code, and other significant fields. Minor updates, such as non-clinically relevant note updates, do not qualify.
_lastUpdated=gt2014-09-24or_lastUpdated=lt2015-09-24T12:00:00.000Z - May be provided up to two times, and must use the
-
category: string
The category of observations.
Example:category=laboratory -
code: string
The code or component-code of the observation type.
- May be a list of comma-separated values. A system must be provided for each code.
- Searches
Observation.codeandObservation.component.code.
code=http://loinc.org|3094-0,http://loinc.org|3139-3 -
date: string
The date range that the observation falls within.
- May be provided up to two times, and must use the
eq,ge,gt,le, orltprefixes. - When a value is provided without a prefix, an implied
eqprefix is used. - When provided twice, the lower value must have a
georgtprefix and the higher value must have anleorltprefix. - May not be provided with
_lastUpdated.
date=gt2014-09-24ordate=lt2015-09-24T12:00:00.000Z - May be provided up to two times, and must use the
-
patient: string
The subject (patient) that the observation is about. This parameter is required if
subjectis not used.
Example:patient=12345 -
subject: string
The subject (patient) that the observation is about. This parameter is required if
patientis not used.
