INTRODUCTION

The United Kingdom National Bariatric Surgery Registry

PUBLICATION OF SURGEON-LEVEL DATA IN THE PUBLIC DOMAIN FOR BARIATRIC SURGERY IN NHS ENGLAND

Summary

The NBSR Committee on behalf of the British Obesity and Metabolic Surgery Society presents the operative outcomes data for NHS patients having bariatric surgery for the three financial years 2013/14 to 2015/16 on http://nbsr.e-dendrite.com.   We use the same definitions of major and minor revision surgery as for 2014/15. The main results are summarised in the table below from the data cut taken on 12 August 2016, with the 2012/15 data copied through from last year’s report.

All NHS data are included and there were no non-contributing hospitals. The total number of hospitals includes private hospitals where these were used to provide additional capacity for the NHS bariatric units. The data shown are those of surgeons currently practising to our knowledge within the NHS and excludes retired surgeons.

* These data include all primary and revision surgery, without subdividing revision surgery into major and minor.  Therefore the numbers include re-operations for complications of the primary procedure (which may not be detected as bariatric operations by HES) as well as conversions to another bariatric procedure.

** The historic HES data volumes are slightly different from those recorded in the 2014/15 COP report due to adjustments made by the HSCIC. Case ascertainment is recorded as primary operations in NBSR / HES recorded data (%).

*** The NBSR mortality data we report are in-hospital deaths and exclude patients who may be readmitted and die due to a complication of surgery within 30 days. The data are adjusted compared to previously reported, since entries on the registry have been changed/edited by contributing surgeons.

**** Data suppressed as low numbers to prevent potential identification of individual patients.

Eight consultants in different hospitals had one death each during the 3-year reporting and none was a statistical outlier. We also report in-hospital mortality for each hospital. In the 3-year reporting period one hospital appeared as a potential outlier at the 99.9% alarm level. The surgeon is not an individual outlier since much of their NHS practice is spread across different hospitals, making the denominator larger.

For this year we present the last 7 years of mortality data according to Hospital Episode Statistics (HES) and the Office of National Statistics (ONS). The in hospital mortality rate recorded by both methods was the same. ONS also records the mortality rate within 30 days of discharge.

* Data suppressed according to the Data Protection Act as low numbers to prevent potential identification of individual patients.

The HES in-hospital mortality rate for 2009/10 – 2015/16 was 0.078% (less than 1 in 1,000) and the ONS 30-day mortality rate was 0.158% (1.6 in 1,000), confirming again the overall safety of bariatric surgery in NHS England.

A future version of the dataset (planned for April 2017) will enable in-hospital mortality to be distinguished from mortality after readmission.

Overall for the 3 years 2013/16, primary surgery:
  • The average patient body mass index (BMI) was 49.1 kg/m2 and the average weight was 136.4kg, indicating that the patients were twice the ideal weight for their height
  • 75.9% patients were female
  • The average number of obesity-related diseases for each patient, for example type 2 diabetes, hypertension, sleep apnoea, functional impairment and arthritis was 3.59
  • There were 12 recorded deaths for an in-hospital mortality rate of 0.05%, equivalent to a survival rate of 99.95%
  • The average length of hospital stay for all operations was 2.6 days

The data presented here for 2015/16 demonstrate increasing disease burden and decreasing length of stay compared to the three years 2013/15, when there were on average 3.57 comorbidities, and the average length of hospital stay was 2.7 days

As before, the ONS data indicate that the in-hospital and 30-day mortality rates continue to be very low for bariatric surgery in England. Bariatric surgery survival is at least as good if not better than many common laparoscopic gastrointestinal procedures.

NBSR Committee
3rd February 2017


BACKGROUND

The first round of Consultant Outcomes Publication in 10 specialties, including bariatric surgery, in summer 2013, followed a call for a culture of openness, transparency and candour from the Francis Report (2013) that dealt with the events leading up to the Mid Staffordshire enquiry 4.  The National Bariatric Surgery Registry (NBSR) publishes its 4th round of individual consultant and unit outcomes data for surgeons in the NHS in England1-3

We were invited by Sir Bruce Keogh to highlight examples of good practice (positive outliers) as well as publishing the names of potential negative statistical outliers. We are also asked to publish more outcomes for 2014/15 than in the previous years. As participation in the NBSR is a mandatory part of provider contracts, this year the NBSR Committee:

  • Publishes the names of the hospitals whose total patient records were >10% fewer than they should be according to HES
  • Adds the  percentage of initial patient records that are ‘green for complete’
  • Sub-divides revision surgery into major and minor, so as to highlight the work of those who take on higher risk major revisions.

We are well aware of the lack of audit back up in many units and the first two are intended to support surgeons in their discussions locally.  Outcome 2, for the first time in NBSR reporting, produces potential negative (and positive) outliers.


OUTCOMES PUBLISHED FOR 2015/16

This year we publish hospital outcomes on NHS Choices so as to highlight unit-level rather than individual surgeon-level outcomes. The new outcomes as well as hospital mortality are:

  • Total number of operations
  • Proportion primary vs major revision vs minor revision
  • Data completion rates ('green for complete')
  • In-hospital mortality

We also report again the same outcomes as in 2014/15 and previously. The new outcomes in 2014/15 were:

  • The names of hospitals whose NBSR entries are more than 10% fewer than they should be according to Hospital Episodes Statistics (HES) (poor case ascertainment)
  • Data completion rates for the initial in-patient record according to the proportion of records that are ‘green for complete’ for each surgeon
  • Reporting of revisional surgery rates according to major and minor, expressed as % of workload of each surgeon.

NOTES ON THESE OUTCOMES

1.  Case ascertainment vs Hospital Episodes Statistics (HES)

As in 2014/15 we reprint here text from the 2013/14 report where we call for hospitals to provide sufficient administrative support to help their surgeons and bariatric teams with data entry:

‘‘It is evident that most NHS bariatric units still don’t have sufficient administrative support to ensure completeness of data entry and internal validation. Although the NBSR became mandatory for NHS providers from 1st April 2013, we remind hospital Trusts of their obligation to:

  • Verify and facilitate consultant and hospital-level engagement with national clinical audit; including providing resource for data validation
  • Respond to audit provider requests to check data accuracy and notification of outlying data
  • Work with clinicians and audit providers to use audit data ‘real-time’ for quality improvement
  • Promote the value of clinical audit across all work streams, not just those involved with COP 5

Our view remains that it is insufficient to rely on individual clinicians alone to ensure there are no missing records, incomplete records or inaccurate data entry and thus possible under-reporting.’’

For the 2015/16 report we report the names of the 12 hospitals whose records were more than 10% fewer than they should have been according to HES, excluding hospitals where there are 10 or fewer patients apparently missing:

  • BRADFORD ROYAL INFIRMARY
  • ROYAL DERBY HOSPITAL
  • MANOR HOSPITAL
  • NORTH TYNESIDE GENERAL HOSPITAL
  • THE JAMES COOK UNIVERSITY HOSPITAL
  • COUNTESS OF CHESTER HOSPITAL
  • THE WHITTINGTON HOSPITAL
  • ROYAL SHREWSBURY HOSPITAL
  • LUTON & DUNSTABLE HOSPITAL
  • KING'S COLLEGE HOSPITAL (DENMARK HILL)
  • NORTH STAFFORDSHIRE ROYAL INFIRMARY
  • HOMERTON UNIVERSITY HOSPITAL

In 2014/15 there were 7 hospitals with poor case ascertainment and in 2013/14 there were 17.

Letters according to the policy on the BOMSS website are being sent to these hospitals to remind them of the requirement to provide sufficient administrative support for data entry, according to our policy http://www.bomss.org.uk/wp-content/uploads/2014/04/NBSR-Policy-for-Managing-Non-Co ntribution-of-Patient-Data-March-2015.pdf. It is possible that individual hospital coding issues are the reason for the apparent differences, and these need assessing locally. Although mandated in the NHS provider contracts, the NBSR committee has no further role other than pointing out the apparent lack of case input.

In addition to naming, and sending letters to, hospitals with more than 10% fewer patient records than indicated by HES we took an executive decision to exclude hospitals from this category if there were 10 or fewer cases missing. One hospital with small operative numbers had >10% missing and 10 or fewer cases missing and so was not named.

Over the 4 years 2012-2016, case ascertainment (the cases recorded into the NBSR expressed as a proportion of the total) has averaged 92%, calculated as the number of primary operations plus major revisions divided by the total operations in HES (which does not include 30-day reoperations). The data need interpreting with caution as the HES records may include non-bariatric operations or not detect all bariatric surgery. If the real volume of surgery was reported then it is likely that overall case ascertainment would be lower than 92%; thus we are confident to highlight the names of hospitals whose submissions are fewer than the actual total. We have no resource to investigate local reasons why submission may not be complete.

2.  Data completion rates – initial record ‘green for complete’

The First NBSR Report details the data fields that need to be completed to make the record go green 6.  If one or more field is missing the data record will remain yellow for incomplete.  The fields are:

Initial information
  • Weight
  • Height
  • Hospital name
  • Funding Category
Baseline comorbidity
  • ASA grade
  • Type 2 Diabetes and duration (where applicable)
  • Hypertension
  • Cardiovascular
  • Sleep apnoea
  • Asthma
  • Functional Status
  • Known risk factors for pulmonary embolus
Operation Record
  • Type Of Operation (Primary, Revision or Planned Second Stage)
  • Operative approach (Laparoscopic, Lap converted to Open, Open, Endoscopic)
  • Operation (select relevant choice)
  • For Revisions Prior Operation Type (where applicable)
Post-op course and discharge
  • Cardiovascular complications
  • Other complications
  • Discharge date
  • Discharged destination
'Are the initial data complete' button

Twenty-six surgeons were potential negative outliers for data completion at the 99.9% alarm level and 4 at the 99% alert level and will be sent letters as per the policy published in 2013 on the BOMSS website 7. Note that the published data are for the 3 years 2013/16 and any records incomplete before the 2015/16 years will still be evident in the current reporting unless they have been updated. Thus a hospital with a local version of the database that was not collecting the relevant record for ‘green for complete’ before 2015/16 would not change its potential outlier status

.

In order for this year’s report to be timely we had one data cut only, 12th August 2016, and there was no opportunity to surgeons to update their data after that. Sixty-five surgeons were positive outliers at the 99.9% level ie had near-complete or complete data completion.

3.  Primary and Revision surgery are here defined as
  • Primary surgery: the first bariatric operation
  • Minor revision: all operations for later complications of surgery, which may or may not involve laparoscopy or laparotomy, and includes band port and band removal procedures
  • Major revision: where one operation is converted to another bariatric operation, including planned second stage procedures

Minor revision surgery includes reoperations for complications of all bariatric procedures, ranging from more minor reoperations on for instance a subcutaneous gastric band port to more major reoperations for complications eg a leak from or stricture in a staple line, or bleed from a gastric bypass or sleeve gastrectomy. The definition also includes re-operations for internal hernia (twisted bowel) that can occur after some types of surgery. Operations such as cholecystectomy are not recorded as revisions with this definition

.

Major revision surgery includes an operation for instance where a vertical banded gastroplasty (now obsolete) is converted to a gastric bypass, or a band procedure is added to a gastric bypass. Experienced surgeons may be more likely to perform more major revisional surgery, compared to younger, newly appointed consultants.

Future reports may sub-divide ‘Minor revision surgery’ into local procedures not involving laparoscopy/laparotomy, and more invasive procedures that involve laparoscopy/laparotomy since the current definition encompasses a wide range of invasiveness. Future reports may also include post-operative complications occurring within or after 30 days of the index procedure.


MORTALITY RATES AND VALIDATION FROM HES

We use the same methodology to calculate in-hospital and 30-day mortality as for the 2012/15 reports 1-3. The definition of in-hospital death used for the NBSR and HES reporting is a death that occurs during the initial hospital stay before discharge. The HES and ONS data for in-hospital mortality were the same for the 7 years 2009/10 – 2015/16, although they use different methods to collect the data.

One hospital had a crude mortality rate above the 99.9% alert level:

Hospital
Mortality rate 2013-2016
Potential outlier level
Northern General Hospital, Sheffield
1/54 patients
99.9% alarm

The patient who died at this hospital was recognised as an extremely high risk patient, and died in 2013/14. As per our policy the surgeon, Clinical Director and Medical Director will be informed according to our policy for identification of potential outliers http://www.bomss.org.uk/wp-content/uploads/2014/04/NBSR-Policy-for-identification-of-potential-outliers-June-2013.pdf, so that appropriate local audit can take place if it has not already.

During the 3-year reporting period 8 surgeons from different hospitals each reported one death. None was an individual statistical outlier. The vast majority of surgeons working in the NHS in England have had no mortalities in the last 3 years under analysis. Using funnel plots, a well-recognised statistical model, none of these signal as an outlier at the 99.9% confidence limit.

It is our policy that all mortalities related to bariatric surgery should be reported into the registry, but we are not able to comment on any mortality that is not. The policy concerning non-submission of mortality data is on the BOMSS website http://www.bomss.org.uk/wp-content/uploads/2014/04/ NBSR-Policy-for-Managing-Non-Contribution-of-Patient-Data-March-2015.pdf.

We report also above the ONS data on mortalities occurring up to 30-days after the initial operation. This includes patients being readmitted to hospital or dying outside hospital without be readmitted. We are not able to report mortality data after 30 days. We reproduce again a paragraph regarding estimating mortality after 30 days from the 2013/14 report 2.

‘‘The current analyses of mortality do not extend beyond 30 days. Although it is theoretically possible to perform a 6-month analysis via the ONS of deaths after surgery for instance from ongoing complications, we do not have the resource to do this. In addition, mortality would have to be checked against individual death certificates, which is beyond our administrative and logistical capacity. Also, the analysis would have to take into account the background rate of mortality in the population unconnected with surgery and therefore the results would be even more difficult to interpret.’’

Overall, the NBSR data and the various HES analyses are entirely equivalent to a US benchmark, the American College of Surgeons Bariatric Surgery Center Network, where the published mortality rate was 0.12% (35 out of 28,616) for patients operated from 2007-10 8.


OTHER OUTCOMES REPORTED

These are:

  • Consultant workload for primary and revision operations excluding gastric balloon placement
  • Operation split by consultant
  • BMI on entry into the weight loss programme
  • Co-morbidity count per type of operation (number of co-morbidities recorded per patient)
  • Obesity-Surgery Mortality Risk Score (OS-MRS) and class per operations and overall per consultant
  • Initial BMI overall per consultant (box and whiskers)
  • Length of stay for primary procedures compared to the rest per consultant
  • In-hospital mortality, described as survival

The co-morbidity count was taken from the NBSR dataset of co-morbidities:

  • Type 2 diabetes
  • Hypertension on treatment
  • Dyslipidaemia
  • Atherosclerosis (includes angina, MI, CABG, stroke, claudication)
  • Sleep apnoea
  • Asthma
  • Functional status (presence of comorbidity defined as unable to climb 3 flights of stairs without resting)
  • Back or leg pain from arthritis
  • GORD
  • Liver disease (suspected NAFLD or worse)
  • Poly-cystic ovarian syndrome (female patients only)
  • Depression (clinically significant depression as a reason for bariatric surgery)

The Obesity Surgery-Mortality Risk Score is the only validated measure of operative risk for patients undergoing bariatric surgery 9. A point is added for each of the following risk factors that are present, up to a maximum of 5 points: age at surgery ≥45 years, BMI ≥50 kg m2, male gender, recorded hypertension, one or more known risk factors for deep vein thrombosis (DVT) / pulmonary embolism (PE). Using the resultant score, complication & mortality rates can be risk-adjusted; the higher the score/group, the greater the risk of surgery. Patients can be stratified for risk according to how many of these risk factors are present. It is normal practice to refer to the calculated scores in three groups:

Group A (0-1 points)
Group B (2-3 points)
Group C (4-5 points)

We worked with the Quality Outcomes Research Unit in Birmingham University (QUORU) to analyse the HES data, and using a refined set of OPCS4 codes were able to estimate the mortality for primary bariatric surgery for the 3 years April 2012 – March 2016 previously highlighted (D McNulty, D Pagano, P Small, R Welbourn unpublished). Due to time limitations we were not able to analyse HES data for any other potential outcome.


PRESENTATION OF RESULTS

Patients are now able to search for hospitals by geography using an added map function and postcode. See the Frequently Asked Questions section on how to interpret this. As before, we present data for each outcome variable either as graphs, bar charts or box and whiskers graphs. Comments are included interpreting the results.

Additional notes:

We were contacted by Sunderland Royal Hospital where intra-gastric balloon data are collected on a different system and are not currently submitted to in the NBSR. Also, a substantial proportion of gastric bypasses in Sunderland are constructed using a loop technique, which it is not possible to record in the NBSR. A loop gastric bypass page is planned for Version 2 of the NBSR to accommodate this changing practice. These differences accounted for the observed discrepancy in their NBSR numbers vs HES.

INTERPRETATION OF RESULTS

We believe the 3-year data for 2013/16 are a correct representation of surgeon and hospital volume, baseline BMI, degree of baseline obesity-related disease, type of operation, mortality and length of stay.

USING THE WEBSITE

FREQUENTLY ASKED QUESTIONS

What does the report show?

It shows the centres that performed NHS bariatric surgery in 2012/15. The map facility allows you to search geographically and by postcode. The hospital unit volume of operations is shown, as well as the volume for the individual surgeons. Mortality data are shown as well as operation split, frequency of revision surgery and degree of obesity-related disease present and length of stay.

How do I access bariatric surgery?

Contact your GP in the first instance and ask for help with your weight problems. If your BMI is 35 or more and you have obesity-related disease that can be improved weight loss, or your BMI is 40 or more, you may be suitable for surgery. In March 2014 the RCS and BOMSS produced Commissioning Guidance that describes how this process works 13 http://www.bomss.org.uk/commissioning-guide-weight-assessment-and-management-clinics-tier-3/ .

Which unit should I be referred to?

Each region has well set-up bariatric surgery multidisciplinary teams with a full complement of specialists to help you with your care. These include dietitians, specialist nurses, physicians, surgeons and anaesthetists. Some patients may benefit from seeing psychologists and physiotherapists as well. The team will discuss with you whether surgery is a good option for you.

Not all the hospitals shown on the website http://nbsr.e-dendrite.com are
bariatric surgery assessment centres (so called Tier 4 specialist centres), they may be hospitals contracted to do the actual surgery after full assessment by the local centre. It is important that you find out which service your local hospital offers. In addition due to local contracting it is possible that you will not have a choice about where you are sent for a bariatric surgery assessment or where the operation would then be done.

If you have a choice of surgery provider we encourage you to look at the data published for each hospital and discuss what it means with your GP.

Which operation should I have?

Discuss this with your surgical team. The expertise for different operations may vary from unit to unit and it is important that you are comfortable with the service you are being offered. Remember that bariatric surgery is one episode in a process of care of severe obesity, which is a lifelong chronic disease.

Does the number of operations a surgeon or unit performs make a difference to the success of surgery?

The BOMSS commissioning guide advises that units should have at least 2 surgeons and the annual volume of procedures should be at least 100 for the hospital and 40 for the individual surgeons. This is because in general for all specialised surgery the higher the caseload the better the operative results are likely to be. For bariatric surgery the staffing infrastructure is also likely to be better as all the required multidisciplinary team should be resourced and available. Read more about this on the BOMSS website 14 http://www.bomss.org.uk/wp-content/uploads/2014/04/BOMSS-Professional-Standards-March-2013.pdf

Some units may have only just been set up or a fully trained consultant surgeon may have only recently joined the unit. Both can explain why the presented numbers may be small.

Which questions should I ask the surgeon?

We would encourage you to ask about experience with particular operations, unit volume and reoperation rates for complications. We would encourage you to ask about how the MDT process works, which members you will meet and how you will be followed up after the surgery. All are important for the success of surgery long term.

Roux en Y Gastric Bypass – the commonest form of gastric bypass, where a small stomach pouch is made and connected to a part of the small bowel (the ‘Roux limb’).  Continuity is restored by connecting the the Roux limb by a Y join to a lower part of the small bowel.  The remaining stomach is left undisturbed.

The National Bariatric Surgery Registry is the result of a collaboration between ALSGBI (Association of Laparoscopic Surgeons of Great Britain and Ireland), AUGIS (Association of Upper Gastrointestinal Surgery), BOMSS (British Obesity & Metabolic Surgery Society) and Dendrite Clinical Systems. The key objective of the registry is to accumulate sufficient data to allow the publication of a comprehensive report on outcomes following bariatric surgery. This will include reportage on weight loss, co-morbidity and improvement of quality of life.
