Abstract:
Objective:To analyze the status quo of bystander cardiopulmonary resuscitation (BCPR) for out-of-hospital cardiac arrest (OHCA) in Qinhuangdao area and its influence on the prognosis of cardiopulmonary resuscitation (CPR).Methods:Based on the Utstein model CPR database of Qinhuangdao, data of 1 162 OHCA patients admitted to the Health Emergency Dispatch Center of Qinhuangdao City from January 2018 to January 2019 were collected, and they were divided into two groups according to whether BCPR was performed or not. The patients' demographic parameters (gender, age), precardiac arrest parameters (location of cardiac arrest), the parameters of the CPR (first aid response time before hospital, initial diagnosis of causes of cardiac arrest, initial cardiac rhythm) and the parameters of the CPR results [whether to achieve on-site restoration of spontaneous circulation (ROSC) and 30-day survival rate] were collected. Multivariate Logistic regression analysis was performed for the relationship between BCPR and on-site ROSC rate. The social characteristics of bystanders implementing BCPR, including gender, age, occupation, educational background, and acquisition method of CPR knowledge, were analyzed.Results:Among the 1 162 OHCA patients, the patients witnessed by professional medical personnel in nursing homes, hospitals and other places and pre-hospital emergency personnel were excluded. 852 OHCA patients were enrolled, among which only 24 patients obtained BCPR (2.8%), and the remaining 828 patients did not obtain BCPR (97.2%). There were no statistically significant differences in gender, age, location of cardiac arrest, pre-hospital emergency response time, primary diagnosis of cardiac arrest causes and initial cardiac rhythm between the two groups. Compared with the non-BCPR group, the on-site ROSC rate and the 30-day survival rate of the BCPR group were significantly increased [on-site ROSC rate: 16.7% (4/24) vs. 5.2% (43/828), 30-day survival rate: 8.3% (2/24) vs. 1.3% (11/828), both P < 0.05]. Multivariate Logistic regression analysis showed that BCPR [odds ratio ( OR) = 32.132, 95% confidence interval (95% CI) was 11.129-65.471], location of cardiac arrest ( OR = 0.080, 95% CI was 1.212-3.125) and response time during pre-hospital emergency treatment ( OR = 0.121, 95% CI was 0.174-0.816) were important factors for on-site ROSC of OHCA patients (all P < 0.01). A total of 30 bystanders participated in the implementation of OHCA patients' BCPR, excluding 2 bystanders of lost follow-up, 28 bystanders with effective return visit. The 28 bystanders of BCPR practitioners were mainly male (85.7%), the age was mainly 18-40 years old (57.1%), the occupation was mainly in the tourism service industry (21.5%), students (17.9%), soldiers (14.3%) and bus drivers (10.7%), and the education background was mainly junior college or above (85.7%), the methods of acquiring CPR knowledge mainly included APP and new media (42.9%) and lectures (21.4%). Conclusions:The BCPR implementation rate of OHCA in Qinhuangdao was only 2.8%. BCPR can improve the success rate of pre-hospital CPR and the 30-day survival rate of OHCA patients. Targeted selection of tourism service industry, students, military personnel and bus drivers as CPR training targets may obtain more significant social benefits.
