Hospital(s): Royal Papworth Hospital NHS FT
Special Interests: Adult Cardiac Surgery
Mr Ng graduated in 1993 from Trinity College, Dublin. He completed his basic surgical training in East Yorkshire. His cardiothoracic surgery training began in 2000 and was based entirely at Papworth Hospital with short stints in Norwich and Oxford. He undertook a two-year period of research in transplantation tolerance at the Transplantation Biology Research Centre of Harvard University from 2005 to 2007.
He was appointed as a locum consultant surgeon at Papworth in 2009 before becoming a substantive appointment in Feb 2011. He has experience in all aspects of adult cardiac surgery. Specialist interest includes high-risk surgery in the sick elderly population, aortic surgery specifically acute aortic dissection emergencies and pulmonary endarterectomy surgery. He is one of four surgeons in the sole national pulmonary endarterectomy programme at Papworth

Risk-adjusted in-hospital survival rate
This graph shows the “in hospital” survival rate of patients who are operated on by the individual surgeon/unit you have selected. “In hospital” means time the patient is in the hospital where they have had their operation. It does not include any time that patients may have spent in other hospitals, either before or after their heart operation.
The data has been through a complex methodology, including the variations in patient risk factors in order to give you a comparative base from which to work from. This means that the survival rates take into account the type and risk of patients being operated on for each surgeon/unit. This is known as risk adjusted survival.
The vertical axis shows the GMC number of the surgeon or the Hospital identifier. In brackets is the total number of patients operated on by the surgeon/unit and the percentage of patients for whom the survival is known. The horizontal axis is the percentage survival. The dashed vertical line shows the risk adjusted survival rate for the UK as a whole. The solid black horizontal line represents the surgeon/unit. What is important here is that the horizontal line crosses the vertical dashed line. If this occurs, it means that the surgeon/unit are within the expected outcomes given the case-mix and risk factors of the patients they operate on.
The icons that sit on the horizontal line should give you more information about your surgeon/team.
The open square is the survival rate with no risk adjustments:
The X is the predicted survival with adjustments
The solid dot is the survival probability after the methodology has been applied.
- If the solid dot is red it means survival is worse than expected
- If the solid dot is black it means that it is within limits
- If the solid dot is green it means that there is significantly higher survival than expected
There is a lot of information on these plots, but the takeaway message is that if the solid black line crosses the dashed vertical line then the survival rate for the surgeon/unit is within expectations and that there is no reason for any concern.
