International Consensus on Cardiopulmonary Resuscitation and Emergency Cardio- Mary Fran Hazinski, MSN,
vascular Care Science With Treatment Recommendations” (CoSTR) developed by the RN, FAHA
International Liaison Committee on Resuscitation (ILCOR).2 As planned, ILCOR is now Andrew H. Travers, MD,
transitioning to a process of continuous evidence evaluation, with the intent to issue MSc
updated systematic reviews and CoSTR statements when prompted by the publica-
tion of new evidence. A description of the evidence review process and a glossary of
terms are available in the 2017 BLS CoSTR summary.3 When indicated, the AHA
will publish focused updates for guidelines related to the areas reviewed by ILCOR.
The first topics selected by ILCOR as part of the continuous evidence evaluation
process are related to BLS, including dispatch-assisted CPR, the use of continuous
versus interrupted chest compressions by emergency medical services (EMS) provid-
ers, and the use of chest compression–only (hands-only) CPR versus CPR using chest
compressions with ventilation in both the in-hospital and out-of-hospital settings.
The evidence evaluated included studies used to support the 2015 CoSTR2 and new
literature published since 2015.
It is important to note that this focused update covers only those topics ad-
dressed by ILCOR’s new continuous evidence evaluation process as of 2017. The
ILCOR systematic reviews use the Grading of Recommendations Assessment, Devel-
opment, and Evaluation methodology and its associated nomenclature for strength
of recommendation and level of evidence. The expert writing group for this adult
BLS–focused update reviewed the studies cited in the 2017 BLS CoSTR summary3
and carefully considered the ILCOR consensus recommendations in light of the
