In 2013-14, 3,3902 adults aged 45 to 64 underwent inpatient bariatric surgery procedures,4 according to latest figures published by the Health and Social Care Information Centre.

This accounts for 53.1 per cent of all such procedures recorded by hospitals3 (6,380).

Today's report also shows a 20.4 per cent decrease in the total number of inpatient bariatric surgery procedures, as compared to 2012-13 (8,020). Nearly half of this decrease can be attributed to one hospital trust now recording bariatric maintenance procedures in an outpatient rather than inpatient setting.5 6

Women account for the majority of bariatric surgery procedures; 4,820 procedures were recorded for women, compared to 1,560 for men. This continues a ten year trend; in 2003-04, 378 procedures were recorded for women, compared to 96 for men.

There were 15 per cent fewer hospital admissions with a primary diagnosis of obesity in 2013-14 (9,330) compared to 2012-13 (10,960), although latest figures are more than five times as high as 2003-04 figures (1,710).7

Statistics on Obesity, Physical Activity and Diet, England 2015, presents a range of information from a variety of recent publications and new analyses not previously published, and shows:

  • London had the highest admission rate for inpatient bariatric surgery procedures (19 per 100,000 of the population) across Commissioning Regions in 2013-14, whilst the Midlands and East of England had the lowest (7 per 100,000 of the population).
  • The proportion of obese children in reception year (aged 4-5) in 2013-14 was 9.5 per cent - higher than in 2012-13 (9.3 per cent) but lower than in 2006-07 (9.9 per cent).
  • The proportion of obese children in Year 6 (age 10-11) in 2013-14 was 19.1 per cent - higher than in 2012-13 (18.9 per cent) and also higher than in 2006-07 (17.5 per cent).
  • The number of prescription items dispensed for treating obesity in 2013 (563,000) rose by 44.0 per cent from 2012 (392,000).This still represents a decrease of 61 per cent from 2009 (1,450,000), when the number of prescription items dispensed for treating obesity reached a peak. This pattern is likely to have been affected by a stock shortage of the drug Orlistat in 2012.
  • In 2013, Orlistat accounted for all prescription items dispensed for the treatment of obesity, at a net ingredient cost of £19.7 million.

Notes to editors

  1. The Health and Social Care Information Centre (HSCIC) was established on April 1 2013 as an Executive Non Departmental Public Body (ENDPB). It is England's trusted data source, delivering high quality information and IT systems to drive better patient services, care and outcomes. Its work includes publishing more than 220 statistical publications annually; providing a range of specialist data services; managing informatics projects and programmes and developing and assuring national systems against appropriate contractual, clinical safety and information standards.
  2. Figures between 1,000 and 100,000 have been rounded to the nearest 10; figures over 100,000 have been rounded to the nearest 1,000; figures over 1 million have been rounded to the nearest 100,000. Percentages have been rounded to one decimal place; percentage calculations are based on un-rounded figures.
  3. Hospital Episode Statistics (HES) is a data warehouse containing details of all admissions to NHS hospitals in England. It includes private patients treated in NHS hospitals, patients who were resident outside of England and care delivered by treatment centres (including those in the independent sector) funded by the NHS.
  4. Bariatric surgery procedures are performed to help weight loss; including stomach stapling, gastric bypass, gastric band and sleeve gastrectomy, as well as gastric band maintenance. The figures reported use HES data on the number of recorded Finished Consultant Episodes (FCEs) in an inpatient setting with a primary diagnosis of obesity and a main or secondary procedure of bariatric surgery.
  5. The HES data presented in this report are for inpatients only, so do not reflect all hospital activity. This should be considered when interpreting the data as practice may vary over time and between regions. In particular, practices vary between hospitals as to whether some procedures are carried out or recorded in outpatient or inpatient settings and any changes in recording and clinical practice can affect the trends in this report.
  6. Derby Hospitals NHS Foundation Trust recorded a decrease of 739 inpatient bariatric surgical procedures in 2013-14 mainly due to use of a specific code for maintenance of gastric band, which contributes to the decrease in national figures. This Trust also recorded, between 2012-13 and 2013-14, an increase from zero to 594 procedures in outpatient settings with a primary procedure code of gastric band maintenance. Outpatient procedures are not included in figures published today due to the poor recording of primary diagnosis code in outpatient settings.
  7. The largest decrease was recorded at Derby Hospitals NHS Foundation Trust, where there were 183 admissions in 2013-14 compared to 920 in 2012-13.
