Expert opinion on evidence after the 2020 Korean Cardiopulmonary Resuscitation Guidelines: a secondary publication

Abstract

Considerable evidence has been published since the 2020 Korean Cardiopulmonary Resuscita-tion Guidelines were reported. The International Liaison Committee on Resuscitation (ILCOR) also publishes the Consensus on CPR and Emergency Cardiovascular Care Science with Treat-ment Recommendations (CoSTR) summary annually. This review provides expert opinions by re-viewing the recent evidence on CPR and ILCOR treatment recommendations. The authors re-viewed the CoSTR summary published by ILCOR in 2021 and 2022. PICO (patient, intervention, comparison, outcome) questions for each topic were reviewed using a systemic or scoping re-view methodology. Two experts were appointed for each question and reviewed the topic inde-pendently. Topics suggested by the reviewers for revision or additional description of the guide -lines were discussed at a consensus conference. Forty-three questions were reviewed, including 15 on basic life support, seven on advanced life support, two on pediatric life support, 11 on neo -natal life support, six on education and teams, one on first aid, and one related to COVID-19. Fi-nally, the current Korean CPR Guideline was maintained for 28 questions, and expert opinions were suggested for 15 questions.
