BackgroundAdherence to cardiopulmonary resuscitation (CPR) guidelines in treatment of in-hospital cardiac arrest (IHCA) have been associated with favourable patient outcome. The aim of this study was to evaluate if compliance with initial CPR guidelines and patient outcome of witnessed IHCA events were associated with the place of arrest defined as monitored versus non-monitored ward.MethodsA total of 956 witnessed IHCA events in adult patients at six hospitals during 2018 to 2019, were extracted from the Swedish Registry of Cardiopulmonary Resuscitation. Initial CPR guidelines were: ≤1 min from collapse to alert of the rapid response team, ≤1 min from collapse to start of CPR, ≤3 min from collapse to defibrillation of shockable rhythm.ResultsThe odds of compliance with guidelines was higher on monitored wards vs non-monitored wards, even after adjustment for factors that could affect staffing and resources. The place of arrest was not a significant factor for sustained return of spontaneous circulation, survival at 30 days, or neurological status at discharge, when adjusting for clinically relevant confounders. Compliance with initial CPR guidelines remained a significant factor for survival to 30 days and favourable neurological outcome at discharge regardless of other confounders.ConclusionCompliance with initial CPR guidelines was higher in witnessed IHCA events on monitored wards than on non-monitored wards, which indicates that healthcare professionals in monitored wards are quicker to recognize a cardiac arrest and initiate treatment. When initial CPR guidelines are followed, the place of arrest does not influence patient outcome.Copyright © 2024 The Author(s). Published by Elsevier B.V. All rights reserved.
