BCIS / CCAD project

• Dataset 5.1.2

• Data collection / transmission

• Pilot site experience

• Future plans

Dataset

• Version 5.1– Finalised at meeting 12-2-03

• 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

• www.bcis.org.uk/• www.ccad.org.uk/ccadweb.nsf

BCIS / CCAD

• Practical issues– Collecting the data– Transmitting the data

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

Outcome

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– 0207 391 8028

• 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

Extra Information

• Additional slides with details of– Dataset version 5.1 version code– Volatile menu items

Dataset – Version Code

• Version history– 5.1 as ‘finalised’ in Feb 2003– 5.1.1 as presented at London Roadshow– 5.1.2 as presented at Leeds Roadshow

• Plan to present BCIS and SCTS datasets to ISB Jan 2003


5.1.2


5.1.2Version 6:After approval of definitions by the Information Standards Board


5.1.2

Increments whenever a new menu item is added to volatile lists (e.g. new DES)

Version 6:After approval of definitions by the Information Standards Board


5.1.2Version 6:After approval of definitions by the Information Standards Board

Increments whenever a new menu item is added to volatile lists (e.g. new DES)

Increments with subtle changes in text , typos, clarification of definitions etc.

Dataset fields

• Important aspects not contained in current dataset– (Structure)– Appropriateness– Process– Outcome

• Current definitions of clinical syndromes• Track the use of new equipment

– Drug eluting stents– Distal protection– Etc.

Dataset 5.1 examples

• Indication for intervention– 1. Stable – angina– 2. Stable – coronary anatomy– 3. ACS – no acute STEMI– 4. ACS - primary PCI for STEMI (no lysis)– 5. ACS – Facilitated PCI for STEMI (lysis + PCI)– 6. ACS – Rescue PCI (failed lysis)– 7. ACS – PCI for re-infarction no lysis– 8. ACS – Rescue PCI for re-infarction (failed lysis)– 9. Staged procedure– 10. Hybrid procedure– 11. Acute / subacute thrombosis at recent PCI site (30/7)– 12. Bail out following diagnostic cardiac catheterisation

Volatile menus

• 8 fields with volatile menu items– Drug Eluting Stents– Emboli protection– Diagnostic devices– Procedural devices– Thrombus removal– Brachytherapy– Arterial access management– Peri-procedure drugs

Volatile menus

• Any potential changes to be directed to BCIS audit secretary (PFL)– Discussed with BCIS Council audit committee– CCAD informed

• update dataset version held with Tony Dallimore– update spreadsheet on BCIS– update CCAD web site and Lotus Notes

Dataset stakeholders

• BCIS– Detailed analysis of most of dataset– Track activity and changes in patterns of Rx

• Structure• Appropriateness• Process• Outcome

• Roger Boyle– NHS data– Appropriate professional self regulation

• DOH (general public)– Provision of safe care

• Hospital outcome of stable SV disease
