(2) what his latest estimate is of the highest number of live concurrent users of the Lorenzo software system across English NHS trusts (a) at any one time and (b) on any one day.
The numbers of regular users of Release 1 of the Lorenzo software system in the national health service bodies concerned are as follows:
Number Five Boroughs Partnership NHS Trust 43 Bradford Teaching Hospitals NHS Foundation Trust 12 University Hospitals of Morecambe Bay NHS Trust 96 Hereford Hospitals NHS Trust 7 South Birmingham Primary Care Trust 16
These figures exclude other registered users who use the system only occasionally.
The highest number of live concurrent users across English NHS trusts at any one time, to date, is 19. This occurred on 6 October 2009. The number of concurrent users of the system is lower than the aggregate number of regular users because clinicians spend the majority of their time working directly with patients. Time spent using the system is relatively short, and in most care settings, users will log in and log out of the system repeatedly throughout the day.
