GMC: 3406881


Special Interests: Adult Cardiac Surgery, Thoracic Surgery, Transplant

I am a Consultant Cardiothoracic Surgeon at Freeman Hospital, Newcastle upon Tyne and Professor of Cardiothoracic Surgery and Cardiopulmonary Transplantation in the Faculty of Health and Life Sciences at the University of Northumbria. I was appointed as a Consultant in December 2000 after training in Cambridge, Newcastle and Toronto in cardiac, thoracic and cardiopulmonary transplant surgery.

I currently practice widely in all forms of adult cardiac surgery including cardiopulmonary transplantation. I have a particular interest in minimally invasive cardiac surgery, mitral valve repair, aortic surgery and TAVI and am certified to use the Da Vinci surgical robot system.

I have been an Assessing Examiner for Intercollegiate Basic Surgical Examinations at the Royal College of Surgeons of England and a College Assessor. I am a Specialty Advisor for the General Medical Council and an advisor in Cardiac Surgery for NICE. I am a member of the Specialist Advisory Committee in Cardiothoracic Surgery and am the Specialty Program Director for CORESS. I am a Fellow of the Faculty of Surgical Trainers of the Royal College of Surgeons of Edinburgh and Fellow of the Royal College of Physicians.


In 2017 I was elected as a Trustee to serve on the Executive of the Society for Cardiothoracic Surgery in GB and Ireland.

I was Director of Cardiopulmonary Transplantation at Freeman Hospital (one of the largest transplant programs in the UK) between 2010 and 2016 and am Deputy Chair of the Cardiopulmonary Transplant Advisory Group to NHS Blood and Transplant. I am a clinical advisor for the Care Quality Commission and an Expert for the Parliamentary and Health Service Ombudsman.

I am now the Director of Quality and Patient Safety for Newcastle Hospitals NHS Foundation Trust.

My research interests focus on heart and lung transplantation and human factors in cardiothoracic surgery.

I have travelled widely assisting heart and lung transplant programs in India, Sri Lanka, Saudi Arabia and Turkey.

Additional Information

Number of lung cancer operations performed in 2017: 

Stephen Clark works as part of a team of thoracic surgeons at
Click here to see data on how this team performed in 2017, including;

  • the number of operations to remove lung cancer performed by each surgeon in the team
  • the adjusted survival rates 30, 90 and 365 days after surgery to remove lung cancer
  • the length of time (defined as median days) patients having cancer surgery at this Trust spend in hospital.
  • the percentage of patients readmitted to hospital within 90 days of surgery
  • the pooled resection rate of Trusts served by this surgical unit

This data comes from the Lung Cancer Clinical Outcomes Publication.  This project makes the results achieved by surgical teams treating lung cancer within NHS England available to the public.

The latest report covers operations performed in 2017.  More information about this project is available here.

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.

For example

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.
