Our study is subject to the usual limitations of a retrospective design, including the accuracy of data collection and the potential for measured and unmeasured confounders that may account for the observed outcomes. In addition, our study focused exclusively on the influence of the "code leader." Consequently, we did not evaluate the influence of the "skills paramedic" on skills success rates or ROSC. Although we found a relationship between OHCA case volume and ROSC, we do not know the reason for these differences. Additional study is needed to investigate the specific resuscitation traits of the more experienced paramedics that might explain their increased likelihood of attaining ROSC. Moreover, additional studies are needed to correlate these findings with longer-term outcomes such as hospital discharge and neurological function.
