"Premature death and disability from sudden cardiac arrest continues to be a serious public heath burden. Cardiac arrest surveillance has sought to understand socio-demographic risk factors and geographic disparities of out-of-hospital cardiac arrest (OHCA) among cities, but little is known about such disparities at the neighborhood level. Understanding neighborhood-level risks is invaluable in guiding resource allocation, service provision, and policy decisions to improve public health and safety outcomes in a community. Mesa is developing an evidence-based strategy to promote cardiac health and improve survival from OHCA. The problem is the Mesa Fire and Medical Department (MFMD) has not analyzed its medical records data to identify at-risk populations or areas within the city with a high-incidence of OHCA.The purpose of this applied research project is to investigate the spatial patterns of OHCA incidence in Mesa to identify neighborhoods and public occupancies with the highest risk. Descriptive research methods were employed to answer the following questions: a) what is the morbidity and mortality of OHCA in Mesa, Arizona; b) are there particular characteristics of a population that place neighborhoods at greater risk for OHCA incidents; c) which neighborhoods in Mesa demonstrate a high incidence of OHCA but low rates of bystander CPR, and d) are there public locations in Mesa with persistently high annual incidence of cardiac arrests per site that might benefit from a public access defibrillator program? Clusters of OHCA events were found in neighborhoods with socially isolated older persons, as well as low-income minority populations."
