Methodological Preamble and Link to Published Systematic Review
The continuous evidence evaluation process for the production of Consensus on Science with Treatment Recommendations (CoSTR) started with systematic review triggered by the EIT Task Force in 2019 (1) (PROSPERO CRD42018093369). Evidence for adult and pediatric literature was sought and considered by the EIT Task Force. 2023 Search strategy (Appendix A) was reviewed and updated by Samantha Johnson, Information specialist at University of Warwick. Additional scientific literature was published after the completion of the systematic review and identified by the EIT Task Force and is described before the justifications and evidence to decision highlights section of this CoSTR. These data were taken into account when formulating the Treatment Recommendations.

Background
There is wide variability in survival among hospitals caring for patients after resuscitation from out of hospital cardiac arrest (OHCA). Regionalisation of care into specialist centers has played a vital role in the management of time-critical illnesses through concentration of services and greater provider experience (e.g. trauma, stroke services). The adoption of specialised post-cardiac arrest care at a cardiac arrest center (CAC) may improve long-term survival from OHCA. Previous studies have reported an association between survival to hospital discharge and transport to CAC but there is inconsistency in the hospital factors that are most related to patient outcome.(1)
The International Liaison Committee on Resuscitation (ILCOR) last considered the evidence in 2020 and concluded that specialist CAC may be effective despite a lack of high-quality data to support its implementation.(2) Since this review, new data examining the impact of CAC has been published and this updated PICOST will review and update the evidence base.
Definition of Cardiac arrest center/CAC:
Cardiac arrest centers are defined by the Association for Acute Cardio-Vascular Care of the European Society of Cardiology as specialized institutions offering all recommended treatment options for patients with OHCA, including access to a coronary angiography laboratory with 24/7 PCI capability, targeted temperature measurement (TTM), extracorporeal membrane oxygenation, mechanical ventilation, and neurological prognostication.(3) We adopted a strict definition of CAC, only institutions with the capability for 2 or more of the above interventions and explicitly referred to by study authors as CACs (or synonymous terms such as critical care medical center, tertiary heart center, regional center) were accepted.(4) We excluded studies which used high volume (number of cases/patients) or PCI capability as the only distinguishing characteristics.
Consensus on Science
Sixteen studies were included in our review (Figure 1, Table 1).(5-20) Risk of bias assessment can be found in Table 2a & b.
For the critical outcome 1 of survival to 30 days with favorable neurological outcomes, we identified very low certainty evidence (downgraded for risk of bias, inconsistency and imprecision) from 2 observational studies (evaluating over 40000 patients) that showed improved outcomes. (6, 7) One RCT which evaluated only patients post-non-STEMI was excluded from analysis.(5) , Because of a high degree of heterogeneity, no meta-analysis could be performed (Figure 2).
For the critical outcome 2 hospital discharge with favorable neurological outcomes, we identified very low certainty evidence (downgraded for risk of bias, inconsistency and imprecision) from 9 observational studies (evaluating over 110000 patients) that showed improved outcomes. (6, 8-15). One RCT which evaluated only patients post-non-STEMI was excluded from analysis.(5) Because of a high degree of heterogeneity, no meta-analyses could be performed (Figure 3).
For the critical outcome 3 survival to 30 days, we identified very low certainty evidence (downgraded for risk of bias, inconsistency and imprecision) from 2 observational studies (evaluating over 40000 patients) that showed improved outcomes. (7, 11) One RCT which evaluated only patients post-non-STEMI was excluded from analysis.(5) Because of a high degree of heterogeneity, no meta-analyses could be performed (Figure 4).
For the critical outcome 4 of survival to hospital discharge, we identified very low certainty evidence (downgraded for risk of bias, inconsistency and imprecision) from 11 observational studies (evaluating over 110000 patients) that showed improved outcomes.(6, 8-17) Because of a high degree of heterogeneity, no meta-analysis could be performed (Figure 5).
For the important outcome of return of spontaneous circulation, we identified very low certainty evidence (downgraded for risk of bias, inconsistency and imprecision) from 3 observational studies (evaluating over 50000 patients) that showed improved outcomes. (7, 9, 16) Because of a high degree of heterogeneity, no meta-analysis could be performed (Figure 6).
Treatment Recommendations
We suggest adults with OHCA should be cared for in cardiac arrest centers (weak recommendation, very-low certainty evidence).
Justification and Evidence to Decision Framework Highlights
In making this suggestion, the EIT taskforce considered the following:
- This topic was prioritized by the EIT Task Force based on ongoing interest in improving patient outcomes following OHCA.
- We defined a cardiac arrest centers as specialized institutions offering two or more recommended treatment options for patients with OHCA, including access to a coronary angiography laboratory with 24/7 PCI capability, TTM, extracorporeal membrane oxygenation, mechanical ventilation, and neurological prognosticationcardiac arrest centre as those providing target temperature management and cardiac invention.
- Expedited transfer to a cardiac arrest centre for non-ST-elevation out-of-hospital cardiac arrest (ARREST) trial was published in 2023.(5) The results did not show any benefits in patients transferred to CAC. Based on their results, we are unable to recommend for or against transferring OHCA adults with presumed cardiac cause presenting with non-STEMI with prehospital ROSC to a CAC, as this RCT was in a very specific urban city setting.
- Given the lack of generalisability, we included published data from non-randomised studies in our review.
- We considered the successful implementation of regionalized care for trauma, stroke and STEMI with improved outcomes.
- We reflected on the high level of resources required, particularly in regions with no regionalized emergency transport in place for other conditions (e.g. trauma, stroke, STEMI) and concluded that the benefits potentially outweigh issues associated with implementation of CAC.
- We recognised that implementing this recommendation may be resource and cost intensive, and whilst it has been successfully implemented in some countries, it may not be feasible in all regions.
- There was insufficient data for subgroup analyses to make any recommendations about specific subgroups including age group, presenting rhythm, primary versus secondary transfer, except from one RCT in a very specific setting.
• We did not identify any studies on pediatric patients or in-hospital cardiac arrest in this review.
Knowledge Gaps
- There were no studies identified that evaluated this question in the pediatric and in-hospital setting.
- Most studies only reported short term outcomes until hospital discharge, future studies should document long term neurological intact survival.
- There was a lack of studies that evaluated the long-term benefits and the impact on patient reported outcomes (21)
- There were insufficient data to allow for evaluating the effect of care at CAC in specific subgroups (e.g. age, cardiac aetiology, shockable or no-shockable rhythm)
- There were no studies that reported on the cost-effectiveness of transferring and or caring for patients at cardiac arrest centers
- There were no studies that evaluated any negative outcomes associated with bypassing nearest hospitals (e.g. de-skilling in post-arrest management) and transferring patients to cardiac arrest centers
- There is insufficient evidence to evaluate what is a safe distance or time for transport
- There were no studies that examined the impact on families, particularly those from remote regions.
- There were no studies that evaluated the potential impact on organ donation.
- There is insufficient data from large RCT including a broad variety of populations and aetiology of CA, as all studies but one are observational trials.
