1 PPCI - it’s 24/7 or not at all? Dr JIM HALL CONSULTANT CARDIOLOGIST JAMES COOK UNIVERSITY HOSPITAL MIDDLESBROUGH

2 NO CONFLICT OF INTEREST TO DECLARE

3 PPCI Is it justifiable to have a system that includes treating STEMI patients with PPCI in some units ‘when available’ e.g. 9-5 Mon-Fri and not uniformly in a Heart Attack Centre where PPCI is available ‘all the time’ (24/7) ?  S  n

4 PPCI Is it justifiable to have a system that includes treating STEMI patients with PPCI in some units ‘when available’ e.g. 9-5 Mon-Fri and not uniformly in a Heart Attack Centre where PPCI is available ‘all the time’ (24/7) ?  Systems with part-time PPCI produce inferior patient outcomes

5 PPCI Is it justifiable to have a system that includes treating STEMI patients with PPCI in some units ‘when available’ e.g. 9-5 Mon-Fri and not uniformly in a Heart Attack Centre where PPCI is available ‘all the time’ (24/7) ?  Systems with part-time PPCI produce inferior patient outcomes  Not justifiable in England in 2009

6 PPCI 24/7 – the key issues  PROCESS EFFICIENCY  INSTITUTIONAL COMPETENCE  TRANSPORT TIMES

7 PPCI 24/7 – key issue  PROCESS EFFICIENCY

8 ST ELEVATION ACUTE MYOCARDIAL INFARCTION STEMI EFFECTIVE PATHWAY FOR STEMI PATIENTS RIGHT PATIENT RIGHT PLACE RIGHT TIME

9 EFFECTIVE PATHWAY FOR STEMI PATIENTS RIGHT TIME? AS SOON AS POSSIBLE ISCHAEMIC TIME onset to call call to diagnosis diagnosis to PCI facility = drive timeC2B PCI facility to balloon = D2B

10 EFFECTIVE PATHWAY FOR STEMI PATIENTS SYSTEM DESIGN  Understand the steps in the process  Simplify the system  Set your metrics  Monitor Modernisation Agency: Improving flow www.modern.nhs.ukwww.modern.nhs.uk

36 Part time PPCI (9-5) Justifiable if >3 hour drive time to HAC or > 1 hour drive time to HAC + zero process delay + 9 - 5 volume ~200/yr (requires >1M pop n )

37 Part time PPCI (9-5) Justifiable if >3 hour drive time to HAC or > 1 hour drive time to HAC + zero process delay + 9 - 5 volume ~200/yr (requires >1M pop n ) not applicable to England in 2009
