Application Name: Platform Version Number: 2.0
Background: I’m trying to get the latest observation by patient UUID and Concept UUID using the REST Web Services API.
I’m testing on int02 and have two vitals encounters where I collect the “Temperature ©” concept (id/UUID: 5088/5088AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA) for the “Darius Manual Test” patient (patient UUID: 10c20de9-4606-40b1-b2a9-b7ba53410120)
The following CURL request returns two observations for this concept:
curl -X GET --header 'Accept: application/json' -u admin:Admin123 'http://int
02.openmrs.org/openmrs/ws/rest/v1/obs?patient=10c20de9-4606-40b1-b2a9-b7ba53410
120&concept=5088AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA'
Response:
{
"results": [{
"uuid": "d292c562-a7b4-4709-a6f7-c627eef35169",
"display": "Temperature (C): 37.0",
"links": [{
"rel": "self",
"uri": "http://int02.openmrs.org/openmrs/ws/rest/v1/obs/d292c562-a7b4-4709-a6f7-c627eef35169"
}]
},
{
"uuid": "9acdab1f-ab33-4cc3-b606-58b95c1d62a2",
"display": "Temperature (C): 40.0",
"links": [{
"rel": "self",
"uri": "http://int02.openmrs.org/openmrs/ws/rest/v1/obs/9acdab1f-ab33-4cc3-b606-58b95c1d62a2"
}]
}]
}
I would like to return the latest observation only.
Questions:
- Is the order of observations guaranteed to return the latest observation always? For example, if I add &limit=1&startIndex=1 will I always get the latest observation?
- If the answer to number 1 is ‘no’ is there a url parameter I can use to get the latest observation? (I know bahmni uses &scope=latest, but I don’t know if this is available in OpenMRS)
Thanks! Craig
