BAUS has a long and impressive track record of data collection beginning with establishment of its cancer registries in 1999 to its current collaboration with The National Consultant Information Programme (NCIP) as the vanguard specialty for development and roll-out of the NCIP data portal for benchmarking and quality improvement.

BAUS is committed to the collection of accurate outcome data as a powerful tool to facilitate improvements in clinical practice.  We believe that accurate data on outcomes drives the highest standards of surgery, helps patients make informed decisions about their care and support surgeons' needs for professional revalidation. We fully support UK urologists’ engagement with the collection of accurate outcome data through:

  • provision of the 2017 - 2019 procedure-based registry outcomes data for urological procedures on the BAUS website;
  • use of the BAUS registry data for research;
  • development and implementation of focussed, high impact snapshot audits (see below) that answer specific clinical questions in urology;
  • clinical leadership and specialist expertise on urology procedures, pathways and outcome metrics for inclusion in the NCIP online data portal (see below), and supporting roll-out of the portal to urologists; and
  • clinical leadership and expertise to GIRFT on clinical coding in urology, which underpins the collection of accurate outcomes data in the NCIP portal.

BAUS Registries and the Clinical Outcomes Programme (COP)

Between 2012 and 2020, we published individual surgical outcome data for six urological procedures as part of NHS England’s COP programme on NHS Choices, as well as a more comprehensive set of individual surgeon and unit level outcome data on our website.

Outcomes for individual procedures by surgeon, hospital & region for the period 2017 to 2019 can be accessed by selecting the appropriate icon below.

Verification of data

At the time of BAUS’s participation in this programme, the Clinical Outcomes Publication (COP) programme was mandated in England and Scotland. Although we did collect data from some surgeons practising in Wales, Northern Ireland and the Irish Republic, submission of their data was voluntary, and we could only publish their data if they give their express consent.  

All data were entered voluntarily and could not, therefore, be independently verified by BAUS. However, we have used Hospital Episode Statistics (HES) to identify units that did not return any data, but were unable to use it to check data accuracy.  As a result, we recognise that there may be errors in the output, although individual surgeons were given several opportunities to check and validate their own data.  Some surgeons' returns may be incomplete, either because they were unable to submit their data due to time constraints, or because they lacked support from their Trusts for data collection and/or submission.

Individual surgeons' data ceased to be published by COP on NHS Choices in 2019.  BAUS stopped collecting and publishing outcomes data for procedures in 2020.

BAUS Snapshot Audits

From 2018 onwards, BAUS started to change the emphasis of its audit programme, moving from collection of data in procedure-based registries to snapshot audits which are focussed, high-impact studies that answer specific clinical questions and provide unit level feedback to support best practice and quality improvement.

The first of these, the Bladder Outflow Obstruction (BOO) audit, was undertaken during the early part of 2020 and the results were presented at the BAUS 2020 Virtual Annual Meeting. The Renal Colic audit was launched in November 2020 with data entry during March 2021, and will report in mid-2021.  The Management of the Lower Ureter in Nephroureterectomy audit is ongoing and will report in 2022. A snapshot audit on Emergency Ureteric Injury Management in the UK will be launched in 2022.

The National Consultant Information Programme (NCIP)

NCIP has created an online portal that enables NHS consultant surgeons to review information about their clinical activity and their patient outcomes.

The portal provides access to individual outcomes data and unit-level data across a range of surgical specialities.  It is intended to support NHS Consultants in England as part of their personal learning and development.  It provides both local and national benchmarks against which Consultants can review and access their patient outcomes, with the aim of delivering improved patient care.  

Frequently-asked questions (FAQs) on the NCIP portal can be found by clicking here

BAUS has provided the clinical leadership and specialty expertise to co-develop the dashboards and metrics for urology in the portal.  Urology is the vanguard surgical specialty for rollout of the NCIP data portal to all NHS surgical units in England in 2021.  It is expected that all Consultant Urologists in England will have access to the web-based portal by December 2021.


Audit of surgical activity is not a new concept to most surgeons. It was recognised over 150 years ago (see below) and, whilst there has been no requirement for clinicians to publish outcomes data, a significant number of urologists have been involved in clinical audit and outcome assessment for many years.

Soon, there will be a time where our scholars & colleagues will not be satisfied with general comments on surgical quality outcomes – instead, they will call any physician a charlatan who is incapable to quantify his results"
