The chairman of the Royal College of General Practitioners, Dr Rebecca Payne, said at the time that she was very concerned about the potential impact of this on practices in north Wales, because 89 out of 118 practices were with EMIS. It's hard to see how we have the clinical staff in Wales to mitigate the potential problems that might arise. But going on from that to changing IT systems, obviously it has the potential to create all sorts of practical difficulties when it sometimes has to happen, of course, because existing systems become outdated or technology moves on. There are many people who think it will take three years before all patient records will have settled down on replacement systems, and patients need medical record integration between primary and acute settings, and current circumstances in north Wales are not producing this. So, can the Minister tell me what specific measures we're taking in north Wales to minimise both patient suffering and lost opportunity to deliver improved patient efficiency in this region?
