Summary & Timescale of the Data
The data collection period was from 1 January 2014 to 31 December 2015.
4,166 procedures were recorded from 183 consultants at 113 centres in the United Kingdom, including 127 private patients from 36 consultants. Four of the consultants returning data are not BAUS members.
Hospital Episode Statistics (HES) for 2014 and 2015 indicate that there were 2,714 PCNL cases in England. We do not, however, believe that HES data accurately record the total number of procedures undertaken as we are aware there are differences in the way this procedure is coded by different units. However we do think we have received a very good response from the surgeons undertaking this procedure and we estimate that we have collected data on about 90% of the procedures undertaken in England in 2014 and 2015.
- Median number of cases per consultant: 17 (range 1 - 112)
- Median number of cases per centre: 29 (range 0 - 210)
All data were entered by hand; there was no bulk uploading of data from other systems.
