  • 1. NHS Heart Improvement Programme National Infarct Angioplasty Project – review of cardiac networks December 2007NIAP Cardiac Network Survey - September 2007The NHS Heart Improvement Programme received a request from theDepartment of Health to gain a snapshot of reperfusion activity in all of thecardiac networks to provide additional information to support the findings ofthe National Infarct Angioplasty Audit.Phase 1 was a survey (appendix A) of the 31 cardiac networks requestinginformation on the geographical coverage of the network; pre-hospitalthrombolysis services; arrangements for ambulance transfers; hospital basedreperfusion services; and future plans for changes to reperfusion services.All 31 networks responded.Phase 2 focussed on the 04 December meeting with cardiac networks todiscuss the findings of the survey and discuss in more detail the barriers tochange of implementing a PPCI service and learning and sharing experiencesfrom networks across the country.Phase one key findingsService provisionThis question is to gain a picture of where primary PCI is operational. It mustbe noted this may only be in one centre in a network.Of the 31 cardiac networks in England, 65% provide a pre-hospitalthrombolysis (PHT) service, whilst 13% of networks (those in London) do notprovide any PHT services due to close proximity to PPCI centres andambulance journey times being within target limits for the service.74% of networks offer PPCI in at least one centre, whilst 26% do not provideany PPCI services at all. Of the 31 networks, 61% offer a mixture of bothPHT and PPCI services to STEMI patients.This response does not include in-hospital thrombolysis.HIP NIAP Analysis report – V1 1

  • 3. • It must be noted that some networks are very close to providing a PPCI only service e.g., Greater Manchester and Cheshire (12) do not use PHT in Greater Manchester but there are a couple of areas in Cheshire. Ambulance Transfers Cardiac networks were asked to identify the breakdown of arrangements for transfer of STEMI patients to PPCI centres. For those networks that provide PPCI, including those that offer a mixture of PHT & PPCI, 43% of networks transfer all STEMI patients directly to a PPCI centre. For those networks that offer both a PPCI and PHT service, 16% of patients are accessed at a non-PPCI centre before being transferred to a PPCI centre.

All ambulance crews in all networks use 12 lead ECG recording. For those networks only providing a PHT service, 89% of crews are trained to interpret the ECG, and 44% have full access to telelink facilities. For those networks only providing a PPCI service, 87% of crews are able to interpret the ECG and 30% have full access to telelink facilities. Some areas do not use telelink as they use the scoop and run system.

Of those networks providing PHT, 63% use JRCALC defined criteria for itsuse; with 26% using other or local guidelines. 11% of respondents did notindicate what criteria they use.Hospital based reperfusion servicesFor their patch, networks were asked to identify what proportion of hospitalsprovide PPCI in at least one centre and state the arrangements for receivingSTEMI patients. 48% of networks transfer STEMI patients to PPCI centres;26% receive STEMI patients and do not provide PPCI; and 26% of networkshave PPCI centres that receive STEMI patients directly.

  • 5. For those networks that have at least one centre providing PPCI, they wereasked to identify the different times that PPCI is offered to STEMI patients.13 networks offer a 24/7 PPCI service; 7 networks offer the service ‘in-hoursonly’; none of the 31 networks offer a PPCI service ‘in hours’ and atweekends. Five networks stated that they offer ‘other’ PPCI arrangements:-this includes provision of an ‘ad-hoc’ service (if the patient is in the right placeat the right time) and some 8am to 8pm PPCI services.

For example, the PCI centre may offer PPCI 24/7 but areferring DGH may only offer the service ‘in-hours’.Times PPCI providedHIP NIAP Analysis report – V1 5

The limitingfactor to providing a 24 hour service is personnel and balancing the out ofhours rota with providing a full service.HIP NIAP Analysis report – V1 6
  • 7. Planned changes to current reperfusion servicesNetworks were asked to state any planned changes to either the PHT or PPCIservices offered within the next two years. Those networks that stated theyhad ‘no changed planned’ to their PHT service either provide a full PPCIservice already, or do not have any plans to change their current PHT service.For those networks providing PPCI, work is planned to extend the hours ofPPCI service provision.

Itwas agreed to follow this up further at a meeting with cardiac networks, andthis formed the basis for discussions at the 04 December meeting (furtherdiscussion below).

  • 8. The meeting on 04 December focused on further exploring the surveyresponses. Invited to the meeting were cardiac network representatives,members of the NIAP steering group, ambulance service representatives,network clinical leads and NIAP pilot site clinical leads.Discussions at the meeting centred on the current situation regardingreperfusion, future plans, barriers to providing a PPCI service, and anypotential solutions to overcoming these barriers. The main themes of thediscussions focussed around: • Capacity in terms of ambulance availability and cath lab access • Human resource issues • Commissioning • Rural areas with long travelling distances to PPCI centres • Clinical GovernanceCapacity • Ambulance availability • Catheter lab access • Impact on elective workThe availability of ambulances to provide extra journeys and services acrossnetwork boundaries was highlighted as an issue across the country. In orderto provide a full PPCI 24/7 service, an increase in crews and ambulances isneeded, as well as increased communication between ambulance services’ tolook at closer working relationships and tackling the cross boundary issues.An ambulance services strategy was proposed as a potential solution to thisissue, along with networks doing further work to look at the cross boundaryissues and joint working between networks and ambulance services in orderto agree a collective approach to providing a PPCI service.Concerns were raised surrounding the capacity of catheter labs to providePPCI services, particularly out of hours and 24/7. Also, what are theimplications for staff, wards and services at DGH, with increased activity intertiary centres? Some networks stated that they do not believe that theyhave enough cardiologists to provide a full 24/7 PPCI service.A potential solution to this could be to look at moving services to DGH settingsfrom tertiary centres, to alleviate costing/capacity issues of moving servicesout of the DGH with the introduction of PPCI.Human resources • Availability of staff • Hours of work – problems in providing 24/7 • Cardiology rotas • ‘density’ of cardiologists in rural areas • Impact of primary PPCI on DGH CCUThe human resource aspects of providing PPCI are a particular concern for allnetworks. Providing an out of hours or 24/7 service requires a full rota ofmedical and non-medical staff with different skills. The availability of staff toHIP NIAP Analysis report – V1 8
  • 9. provide this service based on their current ways of working may not bepossible, and depending on the location of the catheter labs, may not beachievable. Some areas do not have enough interventional cardiologists toinclude on a OOH/24/7 PPCI rota, and, depending on where the PPCI serviceis located, they may not be based at the interventional centre at all times.When asked to identify barriers to change, in relation to workforce issues, onenetwork stated that “(the) need to cover labs overnight adds significantchange to workforce practice”.Another network saw “consultant and other clinical staff working hours and theunwillingness of Trusts in the Network to enable an out-of-hours rota whichcould mean the supplying Trust losing consultant time the following day” as aworkforce barrier to change.A potential solution to the human resource issues are to look at ways ofworking differently, including the introduction of generic catheter lab staff;multi-skillng of professional roles and extending the ‘routine’ working day.Shared rotas and increased joint working between centres may help to reducethe pressure on the human implications of providing a PPCI service.Concerns were raised about the potential deskilling of cardiology staff inDGHs. Consideration should be given to changes to cardiac care units toaccommodate acute coronary syndrome to ensure current skill levels aremaintained. A further potential solution may be to look at the integration ofDGH interventionalists onto PPCI rotas at tertiary centres.Commissioning • Evidence base and cost effectivenessSome commissioners are sceptical about the value of PPCI and its’ costeffectiveness compared to providing thrombolysis for STEMI patients. Theimpact of providing a PPCI service, whether OOH or 24/7, has massivecommissioning implications for staffing levels, capacity levels and ambulanceservices. There is also a concern surrounding the potential commissioningcosts for cardiac rehabilitation unbundling of the tariff.The provision of a reperfusion commissioning guide with keyrecommendations may help to engage commissioners and aid theirunderstanding of providing a PPCI service, along with a clear clinicalreperfusion strategy implemented across the network. Some networksdiscussed the possibility of introducing a ‘repatriation’ tariff as a potentialsolution to the threat to DGH incomes of a PPCI service provided at a tertiarycentre.Geography • Rural areas with long travelling distances • Use of helicoptersProviding a PPCI service across a large geographical patch, particularly inrural areas, is an issue for most cardiac networks. Journey times forambulances to the nearest tertiary centre, and delays in reperfusion due toHIP NIAP Analysis report – V1 9
  • 10. geographical spread are highlighted as key concerns to implementing a fullPPCI service.Equity issues surrounding the provision of a PPCI service for those STEMIpatients who live a great distance from a tertiary centre should not beoverlooked.Some networks are discussing the use of PPCI and PHT hybrid approachesas a potential solution to development of their reperfusion strategy. Whilst theuse of helicopters to transfer patients to tertiary centres is being considered inthose areas where long journey times cannot be avoided.Clinical Governance • Evidence base • Cross boundary working • Need for single protocol when have mixed provisionMany networks stated that clinical providers require evidence of the clinicalbenefits of PPCI before they further investigate the provision of a full service.The NIAP report and its’ findings will be able to provide clarity around thisissue.It is clear that, if the evidence base clearly suggests better patient outcomesfor PPCI, that there is a need for clear protocols for the provision of PPCI andany PPCI and PHT hybrid approaches to reperfusion. Such protocols shouldalso cover issues relating to transferring patients across network/geographicalboundaries and the governance issues relating to this.This requires development of clear communication channels between allproviders to ensure that the governance arrangements are clear andunderstood and adhered to by all involved.
