Dendrite hosts surgeon specific outcomes websites

In July 2013, HQIP on behalf NHS England, for the first time published the mortality rates for individual hospital consultants in several specialties.

Dendrite Clinical Systems was chosen to develop, design and host two of the websites for in conjunction with the British Obesity and Metabolic Surgery Society (BOMSS), and the British Association of Endocrine and Thyroid Surgeons (BAETS).

“This is a major breakthrough in NHS transparency and over time the data will reveal how an operation or procedure improves the quality of a patient"s life,” said Dr Peter Walton, Managing Director of Dendrite Clinical Systems. “We are delighted to be part of a programme that shows the benefits of publishing surgeon specific data.”


Surgical data from BOMSS in England has revealed an in-hospital mortality rate of 0.07% (equivalent to survival rate of 99.93%), after three recorded in-hospital deaths from 4,389 procedures.

“The publication of surgeon-level data highlights the safety of bariatric surgery and gives patients and other members of the public the opportunity to review the work of individual surgeons,” said Mr Richard Welbourn, Consultant Surgeon, Chair of the NBSR and the President of BOMSS. “We want patients with severe and complex obesity to feel confidence in NHS care and, as surgeons, we want to deliver the best treatment for individuals in the context of team working as well as individual performance.”

The publication of these latest data shows that a total of 105 consultant surgeons contributed to the NBSR and 101 surgeons consented to their data being released (95%). In addition, the data reports that:

There were no potential statistical outliers for mortality or length of stay;

The average length of hospital stay for all operations was 2.5 days;

The average body mass index (BMI) for the patients was 50.6 and the average weight was 141kg, indicating that the patients were twice the ideal weight for their height;

The majority (72.8%) of patients were female;

The average number of obesityrelated diseases for each patient, for example type 2 diabetes, hypertension and sleep apnoea, was 3.6.


“The publication of outcomes of BAETS members demonstrates the high standards of care that patients benefit from in our Specialty,” said Mr John Watkinsin, BAETS President. “We will continue to strive to demonstrate to the public that we are committed to ensuring that patients who undergo all aspects of thyroid and endocrine surgery receive the best possible care.”

The key findings are:

The mortality of thyroid surgery is extremely low, at around 0.1%, with no significant differences between surgeons.

In-hospital lengths of stay have steadily reduced over the years, and most patients are now discharged within 1-2 days of their surgery.

In-hospital complications such as post-operative bleeding requiring re-operation are relatively rare.

The commonest complication after total thyroidectomy is impaired parathyroid function, leading to the need to take calcium or Vitamin D supplements.

Although data submission to the audit has been voluntary, and requires data to be inputted by the individual surgeon, rates of data completeness are good, demonstrating the commitment of BAETS members to the audit.

“The BAETS membership are to be congratulated on taking this bold step in publishing their results; thanked for their honesty in reporting complications; and encouraged to continue to commit their time and effort to entering data. Outcomes can only be improved if first they are measured,” said David Chadwick, Director of Audit, BAETS.

The data is available on the NHS Choices website - - and is also available on two dedicated Dendrite websites. Please click here to access the bariatric website and here to access the BAETS website
