The 2014 National Bariatric Surgery Register report is the second comprehensive, nationwide analysis of outcomes from bariatric (obesity) and metabolic surgery and follows the 2010 first comprehensive NBSR report, both prospective analysis of outcomes from surgery in the United Kingdom and Ireland.

The National Bariatric Surgery Registry is the major source of data on the effectiveness of weight-loss surgery in the UK and the latest published 2014 registry report has data on 18,283 operations operated between 2010 and 2013. It contains pooled outcome data for bariatric and metabolic surgery in the United Kingdom, compiled from 161 surgeons from 137 hospitals and it reveals that between the years 2010 and 2013, the average BMI of bariatric patients increased from 48.5 to 48.8; the average number of obesity-related diseases such as type 2 diabetes increased from 3.2 to 3.4 and the average obesity surgery mortality risk score (OSMRS) increased from 1.6 to 1.8, meaning that patients were becoming increasingly sick at the point of surgery.

However, the Registry also shows that the average post-operative stay has fallen from 3.1 days to 2.7 days. These figures show that the patients are sicker at the point of surgery but their post-op stay in hospital is decreasing, even taking into account an increase in more complex sleeve gastrectomy operations and a fall in gastric band surgery.

The National Bariatric Surgery Registry is part of the British Obesity and Metabolic Surgery Society (BOMSS), plus database specialists Dendrite Clinical Systems.
