Abstract
Few studies have investigated the association between dispatcher-assisted cardiopulmonary resuscitation (DA-CPR) performance and the outcomes of out-of-hospital cardiac arrest (OHCA) among communities with different socioeconomic statuses (SES). A retrospective cohort study was conducted using an Utstein-style population OHCA database in Tainan, Taiwan, between January 2014 and December 2015. SES was defined based on real estate prices. The outcome measures included the achievement of return of spontaneous circulation (ROSC) and the performance of DA-CPR. Statistical significance was set at a two-tailed p-value of less than 0.05. A total of 2928 OHCA cases were enrolled in the high SES (n = 1656, 56.6%), middle SES (n = 1025, 35.0%), and low SES (n = 247, 8.4%) groups. The high SES group had a significantly higher prehospital ROSC rate, ever ROSC rate, and sustained ROSC rate and good neurologic outcomes at discharge (all p < 0.005). The low SES group, compared to the high and middle SES groups, had a significantly longer dispatcher recognition time (p = 0.004) and lower early (≤60 s) recognition rate (p = 0.029). The high SES group, but none of the DA-CPR measures, had significant associations with sustained ROSC in the multivariate regression model. The low SES group was associated with a longer time to dispatcher recognition of cardiac arrest and worse outcomes of OHCA. Strategies to promote public awareness of cardiac arrest could be tailored to neighborhood SES.
Highlights
Despite great efforts over the decades, out-of-hospital cardiac arrest (OHCA) remains a crucial issue in public health worldwide [1]
Prehospital care could be associated with the survival outcomes of patients with OHCA, including emergency medical service (EMS) response time [5], initial cardiac rhythm [6], early defibrillation [7], bystander cardiopulmonary resuscitation (CPR) [8], and even socioeconomic factors [9]
The 37 districts in Tainan were stratified into the high SES (n = 10), middle SES (n = 17), and low SES (n = 10) groups based on the average price of real estate
Summary
Despite great efforts over the decades, out-of-hospital cardiac arrest (OHCA) remains a crucial issue in public health worldwide [1]. Prehospital care could be associated with the survival outcomes of patients with OHCA, including emergency medical service (EMS) response time [5], initial cardiac rhythm [6], early defibrillation [7], bystander cardiopulmonary resuscitation (CPR) [8], and even socioeconomic factors [9]. Both the incidence and mortality rate of OHCA have decreased in Taiwan in recent years, patients in remote areas still tend to have higher mortality [10]. Recent studies have found that the socioeconomic factors might be associated with bystander CPR rate and the outcomes of OHCA [12]
