We investigated the impact of COVID-19 on barriers to dispatcher-assisted cardiopulmonary resuscitation (DA-CPR).<h4>Methods</h4>We reviewed audio recordings of all calls to our national ambulance service call centre during the pandemic (January-June 2020) and pre-pandemic (January-June 2019) periods. Our primary outcome was the presence of barriers to DA-CPR. Multivariable logistic regression was used to assess the effect of COVID-19 on the likelihood of barriers to and performance of DA-CPR, adjusting for patient and event characteristics.<h4>Results</h4>There were 1241 and 1118 OHCA who were eligible for DA-CPR during the pandResuscitation40-47https://www.ebi.ac.uk/biostudies/studies/S-EPMC9596179biostudies-literatureImpact of COVID-19 on barriers to dispatcher-assisted cardiopulmonary resuscitation in adult out-of-hospital cardiac arrests in Singapore.PMC9596179Arulanandam SLim SLToh CFook-Chong SYazid MNg QXLeong BSHo AFWhite AEOng MEShahidah NfalseImpact of COVID-19 on barriers to dispatcher-assisted cardiopulmonary resuscitation in adult out-of-hospital cardiac arrests in Singapore.<h4>Objective</h4>Fewer out-of-hospital cardiac arrest (OHCA) patients received bystander cardiopulmonary resuscitation during the COVID-19 pandemic in Singapore.
