Higher survival rates in denser populations for cardiac arrest

A study in Japan looked at the effects of geographic variation on outcomes of out-of-hospital cardiac arrest (OHCA) through using GIS. Results revealed those in denser areas do better.

After adjusting for age, sex, cause of arrest, first aid by bystander, and the proportion of neighborhood elderly people (greater than or equal to 65 yrs), patients in very high-density areas had a significantly higher survival rate and neurologically favorable one-month survival rate compared with those in very low-density areas. Living in a low-density area was associated with an independent risk of delay in ambulance response.

Distribution of emergency medical services (EMS) centers according to population size may lead to inequality in health outcomes between urban and rural areas.
