BCIS / CCAD project Dataset Data collection / transmission Pilot site experience Future plans

Dataset Version 5.1 –Finalised at meeting Dataset –Sections 1 to 5 (5 = optional fields) –Modifications Overall structure invariant for 2 years (2005) –103 fields and short code options Volatile menu items can be updated at short notice (8) –On BCIS web site and CCAD web site

BCIS / CCAD Practical issues –Collecting the data –Transmitting the data

CCAD Central Server Local Lotus Notes Database Encryption The Basic CCAD Package Lotus Notes front end Local database Encrypted link to CCAD Maintained centrally –Automatic menu update –Automatic software update Limitations: One computer for data input Difficulties linking with other hospital systems No lesion specific data

Analysis of CCAD dataset Benchmarking –Any unit can compare their practice with UK wide average using Lotus Notes software (as MINAP) ONS link –Post discharge event free outcome Death, re-intervention etc. BCIS Council position –Additional analysis to be arranged ? via University statistical department –Methodology of analysis controlled by the profession via BCIS –? 3 year cycle of results analysis –Data monitoring committee as a means of peer review –Accept that the type of analysis will continue to evolve

BCIS / CCAD pilot sites

Plans Pilot sites continue Encourage other sites to start collecting dataset version 5.1 –decide on system to be used –contact CCAD for Lotus gateway set up instructions – Full roll out by April 2004

Conclusions Steady increase in PCI activity in UK –England and Scotland NSF rates for PCI have been exceeded –Increase in PCI:CABG ratio –MACE rates remain satisfactory BCIS-CCAD project –Important progress
