NHS Wales Chief Executive David Sissling has insisted there does not need to be a major inquiry into the health service here, as the organisation is already doing a lot of work to review and improve.
There have been calls for an inquiry into the standards of care in the NHS in Wales, particular after it was 12 people have died over the last 15 months while waiting for cardiac surgery at the University Hospital of Wales in Cardiff.
Critics have demanded a major inquiry, similar to the one carried out by Sir Bruce Keogh, NHS Medical Director in England, into 14 hospital trusts with unusually high mortality rates there.
Mr Sissling told our Health Reporter Rob Osborne: "We're looking mortality rates and other indicators of quality care, we're bringing to bear external expertise where we need to do so, we're bringing the voice of the patient, the influence of our staff to bear."
"So in a sense we're undertaking this work, and we're doing it across all of the health system, not just looking at a very small percentage of hospitals and organisations. We're doing it for every part of the health service in Wales."
