There's a workaround however by implementing a lua script (http://book.orthanc-server.com/users/lua.html) which will protect and unprotect a patient each time a new study is received for this patient.  This way, everytime a new study is received, the patient will be moved to the last position in the recycling order.

```
function OnStablePatient(patientId)
	local protectedStatus = RestApiGet('patients/' .. patientId .. '/protected')
	
	if protectedStatus == '1' then
	  RestApiPut('/patients/' .. patientId .. '/protected', '0')
	  RestApiPut('/patients/' .. patientId .. '/protected', '1')
	else
	  RestApiPut('/patients/' .. patientId .. '/protected', '1')
	  RestApiPut('/patients/' .. patientId .. '/protected', '0')
	end
end
```

The decision was taken to modify the patient recycling order as follows: Whenever a new **instance** is received, its parent patient is moved to the end of the recycling order.
