How exhaustive are out of hospital cardiac arrest registers? The example of the Northern French Alps Cardiac Arrest Registry

Abstract : Improving management and survival of out-of-hospital cardiac arrest (OHCA) is a major public health issue.1 It has become essential to use standardized variables and implement registries to collect high quality data in the real-world setting.2 Besides internal validity, one of the most important requirements for registries is their completeness. We aimed to compare the completeness of the Northern French Alps Cardiac Arrest Registry (RENAU AC) with data from two other emergency systems.
