Dispatcher-assisted bystander cardiopulmonary resuscitation in rural and urban areas and survival outcomes after out-of-hospital cardiac arrest

A systematic review and meta-analysis of the effect of dispatcher-assisted CPR on outcomes from sudden cardiac arrest in adults and children

“…Of the 33 included studies, 15 were conducted in the adult population only 16,20,22,25,27,31,34,37,[41][42][43][44][45]47,49 , five were conducted in the pediatric population ILCOR DA-CPR Systematic Review -Feb 19 2019 10 only 15,18,26,33,40 , and 13 included both adults and children 17,19,21,23,[28][29][30]32,[35][36][37]45,48 . The proportion of males ranged from 52% to 85% (average 66%).…”

“…Survival with favourable neurologic outcome was reported at 1 month (unadjusted data was available in 2 studies 28,45 , adjusted data from 1 study 31 ) and at ILCOR DA-CPR Systematic Review -Feb 19 2019 13 hospital discharge (unadjusted data from 3 studies 18,37,48 , adjusted data from study 40…”

“…Survival was reported at three time points: at hospital admission (unadjusted data in 1 study 28 ), at 1 month (unadjusted data from 5 studies 26,27,28,31,47 , adjusted data from 2 studies 31,47 ) and at hospital discharge (unadjusted data from 9 studies 16,18,22,29,36,37,38,41,48 , adjusted data from one study 40…”

“…These studies had very low certainty with serious risk of bias. For survival at hospital discharge both unadjusted 16,18,20,22,29,34,36,37,38,40,41,48 (OR 1.67; [1.39, 2.0]) and adjusted 18,38,40,48 analysis (AOR 1.40; [1.09, 1.78]) indicated benefit with DA-CPR.…”

“…When comparing DA-CPR to no CPR with regard to survival with favourable neurologic outcome at hospital discharge, both unadjusted 20,34,37,48 from four studies (OR 2.21; [1.44,3.40]) and adjusted 18,40,48 data from three studies (AOR 1.54; [1.35, 1.76]) indicated a benefit with DA-CPR. The same was true for survival with favourable neurologic outcome at 1 month 26,28,45 (OR 1.45; [1.38,1.53] and AOR 1.81; [1.23, 267]).…”
