Bystander CPR increases out-of-hospital CPR survival and direction by 911 telecommunicators increases the frequency of bystander CPR. The majority of 911 centers use Medical Priority Dispatch System which walks 911 telecommunicators through a series of questions that give different instructions based on the caller's answers. Studies have shown out-of-hospital cardiac arrests are only recognized between 79-92% of the time and telecommunicator instructions for CPR can take between 176-285 seconds.
This study reviewed recorded 911 calls of patients who were found to be in cardiac arrest. Calls where the caller was not with the patient and confirmed overdoses were some of the call types that were excluded.
Out of 65 reviewed calls, 28% were not recognized during the actual call. When they were reviewed, 8/18 of the calls were deemed to be recognizable. Themes that were noted were: incomplete or delayed recognition assessment (ie uncertainty in breathing), communication gaps (callers were confused with instructions or questions), caller emotional distress, delayed repositioning for chest compressions, non essential questions and assessments, and caller refusal/hesitation or inability to act.
Bottom line: In addition to bystander CPR training, education on the process and questions involved in calling 911 could be helpful in an emergency.

Should EMS place an advanced airway in out of hospital cardiac arrests? Current studies suggest that advanced airway management is not superior to BVM in pediatric out of hospital cardiac arrest (OHCA).
Pediatric OHCA carries a high mortality rate and those that do survive often have a poor neurologic outcome. This study evaluated BVM vs supraglottic airway (SGA) placement vs endotracheal intubation (ETI) in relation to one month survival and favorable neurological outcomes. SGA and ETI were also grouped together and categorized as advanced airway management (AAM).
This study was conducted using the Pan Asian Resuscitation Outcomes Study Clinical Research Network. 3131 pediatric patients were included. 85% received BVM, 11.8% SGA and 2.6 % ETI. In a matched cohort, one month survival and survival with favorable neurological outcome was higher in the BVM group compared to the AAM group and in the BVM group compared to the SGA group. There was no significant difference noted between the ETI group and BVM group.
Bottom line: In this study, AAM was associated with decreased one month survival and less favorable neurological status in pediatric OHCA.

This was a multistate, prospective, observational cohort of children and teachers attending in person schools in kindergarden through 12th grade where the school districs had the ability to perform contact tracing and determine primary vs secondary infections. During the study period (6/21-12/21) 46 districts had universal masking policies and 6 districts had optional masking policies.
Districts that optionally masked had 3.6x the rate of secondary transmission compared to universally masked school districts. Optionally masked districts had 26.4 cases of secondary transmission per 100 community acquired cases compared to only 7.3 cases in universally masked districts.
Bottom line: Universial masking was associated with reduced secondary transmission of SARS-CoV2 compared with optional masking policies.
