Pre-hospital factors and survival after out-of-hospital cardiac arrest according to population density, a nationwide study.

ABSTRACT:

Aim

This study aimed to examine the impact of population density on bystander cardiopulmonary resuscitation (CPR) and survival after out-of-hospital cardiac arrest (OHCA).

Methods

Through the Danish Cardiac Arrest Registry (2001-2013), OHCAs ≥18 years of presumed cardiac cause were identified, and divided according to the OHCA location in four population density groups (inhabitants/km²) based on urban/rural area-definitions: low (<300/km²), medium (300-1499/km²), high (1500-2999/km²), very high (>3000/km²). The association between population density, bystander cardiopulmonary resuscitation (CPR) and survival was examined using logistic regression, adjusted for age, sex, comorbitidies and calendar-year.
