Statuses permitted are ACT, SUS, STP.After the status has been set to suspended (SUS), the transplant centre is fully responsible for pending requests. If a transplant centre is no longer interested in a certain pending request, the request has to be cancelled by the transplant centre by means of a REQ_CAN message. If the transplant centre does not explicitly cancel a pending request, the request will be processed normally by the requested hub.
After the status has been set to stopped (STP), all pending requests but WOR_REQ are cancelled automatically at the remote hub. In this case, no REQ_CAN messages have to be sent by the transplant centre. The only way to reactivate the patient is a PAT_UPD / PAT_STAT message pair. The PAT_UPD is necessary since it cannot be guaranteed that the patient information is still stored at the remote hub. It is up to each hub how long patient information is retained after the search was stopped.
