In June 2013 surgeon level outcome data was published for the first time.

Outcomes for NHS patients who have received weight loss surgery have been made available to the public. Surgeons have been able to enter their own data into the National Bariatric Surgery Registry database which is hosted by the British Obesity and Metabolic Surgery Society. Outcomes for operations performed by Mr Jeremy Hayden can be obtained by visiting http://nbsr.e-dendrite.com and entering his name in the ‘surgeon’ section.
