So, how I identified any inconsistencies or discrepancies was by cross-validating with different systems. So what we used to get was there was a patient who would have different details in different softwares. So one was a system that the hospital used and one was a system where the national database of all the citizens of UK. And then we used to cross-validate it using that system. So if there was an inconsistency in that and we know for sure that our system is right, then we would escalate it to the higher department and then they would resolve any problems in the national database. If not, if there's a problem in our system, then we used to collaborate with the IT team to make any relevant changes to the person's details.
