Consultant Outcomes 2014

 Second round of data publication shows continued success of bariatric surgery

October 9, 2014

BOMSS welcomes the second annual publication of data on the performance of individual consultant surgeons who perform bariatric surgery across NHS England for the financial years 2012/13 and 2013/14.

Figures released by the National Bariatric Surgical Registry (NBSR) on behalf of BOMSS show 144 consultant surgeons contributing to the NBSR from 49 hospitals. There was 100% consent for publication from surgeons on the NBSR and the results revealed no potential statistical outliers for mortality or length of stay.

The total number of primary operations recorded was 5,419 for the financial year 2013/14. The average length of hospital stay for all operations was 2.6 days.

Overall for the two years, the average patient body mass index (BMI) of patients was 50.2 kg/m2 and the average weight was 139.7kg, indicating that they were twice the ideal weight for their height.

Again over two years there were seven recorded deaths – giving an in-hospital mortality rate of 0.07%, equivalent to a survival rate of 99.93%.

73.5% patients were female and the average number of obesity-related diseases for each patient, for example Type 2 diabetes, hypertension, sleep apnoea, functional impairment and arthritis was 3.71.

It remains important to emphasise to patients that bariatric surgery is one episode in the lifelong chronic disease of obesity. All NHS surgeons work in well-developed multidisciplinary teams (MDTs) dedicated to the care of patients with severe and complex obesity. Our preference was to present outcomes data from units, since it is units that are commissioned to deliver services to patients, not individual surgeons.

This year, patients will be able to search for hospitals by geography using an added map function and postcode. We also show the overall operation volumes for each hospital as well as for each surgeon, which means the data are a more accurate reflection of the whole process of care.

We also publish an additional outcome – that of revision surgery. Surgeons with higher volumes of revision surgery may be referred these patients from other centres due to their expertise. Revision operations can be major surgery, for example where the first procedure failed and it is revised to another bariatric operation. Note that this type of revision surgery carries higher risk due to scarring of the tissues, which occurs after the first operation, therefore it is important to be able to characterise these patients separately from patients having primary procedures. Revision operations can also be relatively minor, such as a replacement of a gastric band port.

We expect that patients will be able to use the data presented in the surgeon graphs to facilitate their consultations with the local bariatric team and help them make informed decisions about surgery.
