43 University of TorontoCity-wide Cardiology RoundsNovember 29, 2007 IMPROVING ACUTE MI CARE PHASE ONE The three University of Toronto Interventional Cardiology Programs, St. Michael’s Hospital, Sunnybrook Health Sciences Centre and the University Health Network, have agreed in principle to improve and optimize existing emergent interventional services by joining forces and thus providing a ‘guaranteed accept’ 24/7 service for patients in the region requiring interventional care for failed thrombolysis, very high risk patients in cardiogenic shock or advanced Killip class, and those with contraindications to thrombolytic therapy. This service, agreed to and signed off on by the Administration of each of the three hospitals, St. Michael’s Hospital, Sunnybrook Hospital and the University Health Network, will apply the following principles: 43
44 University of TorontoCity-wide Cardiology RoundsNovember 29, 2007 PHASE ONE A single contact number to reach emergent interventional care administered by CritiCall A call schedule involving the three programs will be made available to Criticall The interventional cardiologist on call will be the contact at the receiving interventional cardiology centre There will be a NO REJECT policy, as is currently the case with trauma and in some centres organ transplants. In the case that the primary interventional on-call team is already in the midst of an emergent procedure, the second on-call centre will be contacted by CritiCall to accept a new patient. Patients transferred from community hospitals who are deemed stable following the interventional procedure will be transferred back to that hospital within 24 hours of the procedure and could be transferred as soon as the procedure is done and acute vascular access site care has been completed. 44
45 University of TorontoCity-wide Cardiology RoundsNovember 29, 2007 RECOMMENDED TARGETS Door-to-ECG <10 minutes ECG-to-ER Decision<10 minutes Decision-to- Cath Lab <20 minutes Cath Lab-to-Balloon<30 minutes
46 University of TorontoCity-wide Cardiology RoundsNovember 29, 2007 PHASE 2 In the second phase, the University interventional cardiology programs will implement the elements necessary to establish a timely and efficient 24/7 program for primary PCI for patients arriving by ambulance or walking into their own institutions. The ideal call-to-arrival time of CCL staff of <30 minutes must be implemented in this phase by the means most achievable in each individual centre. The possible options that can be implemented include the following: An evening shift that would extend to 11 pm or midnight Ensuring that at least one of the on-call nurses for a particular night lives within a 30 minute radius of the hospital Ensuring that all interventional cardiologists and fellows can be in the hospital within 30 minutes. Cross-training of CICU nurses to help begin an emergent procedure until the arrival of the CCL on call nurses and possibly to assist during the entire procedure 46
47 University of TorontoCity-wide Cardiology RoundsNovember 29, 2007 PHASE 3 In the third phase the University of Toronto interventional cardiology collaboration will implement a strategy of performing primary PCI for eligible patients presenting to GTA hospitals or identified by EMS in the pre-hospital phase. Implementation timelines Phase 1 is to be implemented by July 1, 2007 Phase 2 is to be implemented by April 1, 2008 Phase 3 is to be implemented by July 1, 2008

Rationale for a Trial Comparing Pre-hospital Fibrinolysis vs. Direct Transport for Primary PCI n Among patients with STEMI diagnosed by paramedics in the pre-hospital setting n Insufficient high quality evidence to recommend pre-hospital bypass and direct transport to a PCI center for primary PCI n Lack of clinical trial data comparing pre- hospital fibrinolysis vs. direct transport for primary PCI n Among patients with STEMI diagnosed by paramedics in the pre-hospital setting n Insufficient high quality evidence to recommend pre-hospital bypass and direct transport to a PCI center for primary PCI n Lack of clinical trial data comparing pre- hospital fibrinolysis vs. direct transport for primary PCI

Potential Prehospital Interventions What we do now? –3 lead ECG and drive fast Prehospital diagnosis of STEMI –12 lead ECG and advance ED notification Prehospital intervention –+/- Bypass to PCI site –Prehospital fibrinolysis
Steering group submitted a pilot CIHR – RCT preliminary step Approved Concerns Feasible from a prehospital perspective Feasible from a Toronto perspective Final submission will require data
Objective To determine: Safety and effectiveness Prehospital bypass to PCI center vs. ALS intervention – 12 lead, advance ED notification prehospital fibrinolysis OR BLS intervention – advance ED notification
Primary Outcome Measure 30-day composite of all cause mortality and reinfarction, and stroke defined as any new neurological deficit lasting >24 hours. Survival and reinfarction rates –6 and 12 months
Study Population 11 geographical regions in Ontario –121,959 km 2 –population of 7.5M 10 EMS systems –52 receiving hospitals –within 60 minutes of ≥ 1 of 12 PCI centres.
Where are we? Pulling together our steering cte EMS, medical directors each region Provincial approval – Dec PCI centers representatives Acquiring baseline data estimates from the population and from CCN RCT application to CIHR Feb 2008
We need data to judge what we are getting ourselves into! Prehospital incidence Chest pain – guessing STEMI – even more guessing Within 60 minutes – speculation Reperfusion data CCN data on those that receive PCI Sketchy on those that received TPA or nothing at all
Prehospital Evaluation and Economic Analysis of Different Coronary Syndrome Treatment Strategies – PREDICT PREDICT Investigators Funded by the MOHLTC
What is it? PREDICT –observational study –comprehensive WEB based database –provide incidence numbers to all partners
Study Design Identify the four groups 3 lead and transport to ED 3 lead and transport to ED within 60 mins of a PCI center 12 lead and transport to ED 12 lead and transport to ED within 60 mins of a PCI center TPA 12 lead Bypass
Show me the data!
