Objective The Endoscopic retrograde cholangiopancreatography (ERCP) Quality Network is a voluntary system for submission of data to generate individual report cards and benchmarking. The aim of this study was to compare aspects of ERCP practice between USA and UK participants.
Design Analysis was limited to USA and UK based endoscopists who had each entered more than 30 cases. A number of practice and performance measures were studied including, rates of deep biliary cannulation, sedation use and success in bile duct stone removal.
Setting and patients Patients attending for routine and emergency ERCP in participating tertiary and secondary care units in the UK and USA.
Results 61 US endoscopists performed 18 182 procedures and 16 UK endoscopists 3172, respectively. The UK participants performed less complex procedures as judged by the accepted complexity grading system, 8% versus 35% at grade 3, p<0.001. There was a significantly greater use of sedation as opposed to anaesthesia in the UK 97% versus 34%, p<0.001. UK deep biliary cannulation rate was 93% versus 97%, p<0.001. For small bile duct stones (<10 mm) the UK success rate was 96% compared with 99%, p<0.001.
Conclusion The present data, while not purporting to be an accurate representation of practice in either country, documents good technical success in both cohorts, albeit significantly better in the USA. The inexorable drive to greater accountability and transparency of outcomes in endoscopic practice is likely to lead to increased participation in subsequent benchmarking projects.
