| 目的 探讨影响广州市中心城区院前急救反应时间延长的因素。方法 采用分位数回归法分析影响2015年广州市中心城区院前急救反应时间的因素，其结果与普通最小二乘法得出的结果进行对比。结果 广州市中心城区院前急救反应时间的平均数为14.11分钟，中位数为13.25分钟。医院区位分布、妇产科医生、交通高峰期这三个解释变量是影响广州市中心城区院前急救反应时间延长的因素。结论 分位数回归方法能够较好地应用于院前急救反应时间的研究。我们可根据影响院前急救反应时间的因素来制定相关政策，以提高院前急救质量。 |

| Abstract: |
Objective To preliminarily study the factors leading to extended Pre-hospital Emergency Response Time（PhERT）．Methods Using quantile regression to analyze factors influencing Guangzhou City center Pre-hospital Emergency Response Time in 2015，and comparing the result with those of quantile regression with the standard ordinary least squares（OLS）of Pre-hospital Emergency Response Time in Guangzhou City．Results The mean Pre-hospital Emergency Response Time in Guangzhou City center is 14.11min and that of the median is 13.25min．The location distribution of hospitals，gynecologists and peak hours of traffic are three factors influencing extended Pre-hospital Emergency Response Time in Guangzhou City center．Conclusion Using the quantile regression method is more appropriate for the study of Pre-hospital Emergency Response Time．Through considering the factors influencing Pre-hospital Emergency Response Time, relevant policies can be formulated to improve the quality of pre-hospital emergency care. |
