This document describes the protocol for the study "Emergency Medical Service Personnels Out-of-Hospital Cardiac Arrest Case Volume and Patient Outcomes." This will be an observational cohort study using prospectively collected data from the Danish Cardiac Arrest Registry and the Emergency Medical Coordination Centres in Denmark. The exposure will be defined as the number of out-of-hospital cardiac arrest cases attended by each emergency medical service personnel in the preceding year. The primary outcome will be 30-day survival. Generalized linear model with generalized estimating equations will be used to account for correlation within emergency medical service personnel and units.
