摘要: 目的 探讨急性缺血性脑卒中(AIS)患者院前延迟(PHD)的可干预危险因素及人群归因分析。方法 回顾性分析2023年1月至2025年12月阜阳某三级医院神经内科AIS患者资料,分为PHD组(n=268)与非PHD组(n=129),比较临床资料并进行人群归因分数(PAF)分析。结果 PHD组年龄≥65岁、男性、醒后卒中、未呼叫120、卒中知识知晓不足、发病时无家属陪伴、非工作时间发病、居住地农村占比均高于非PHD组,入院NIHSS评分低于非PHD组(均P<0.05)。多因素logistic回归显示,未呼叫120(OR=1.873)、卒中知识知晓不足(OR=2.345)、发病时无家属陪伴(OR=2.781)、非工作时间发病(OR=2.089)、居住地农村(OR=2.217)均为PHD独立影响因素(P<0.05)。5项可干预因素总体PAF为38.614(95% CI:26.410~51.705)%,按PAF排序依次为卒中知识知晓不足>未呼叫120>发病时无家属陪伴>居住地农村>非工作时间发病。敏感性分析显示,更换PHD切点为3.0、6.0 h,PAF排序无明显改变。结论 5项因素均为AIS患者PHD的可干预独立影响因素,卒中知识知晓不足与未呼叫120为人群层面核心防控靶点。

Abstract: Objective To investigate the modifiable risk factors associated with prehospital delay (PHD) among patients with acute ischemic stroke (AIS) and to perform population attributable fraction (PAF) analysis. Methods A retrospective analysis was conducted on 397 AIS patients admitted to the Neurology Department of a tertiary hospital in Fuyang from January 2023 to December 2025. These patients were divided into the PHD group (n=268) and non‑PHD group (n=129). Clinical data were compared, and PAF analysis was performed to assess the proportion of PHD attributable to specific factors. Results The proportions of age ≥65 years, male sex, experience awakenings after stroke onset, fail to call 120, have insufficient stroke knowledge, lack family accompaniment at the time of symptom onset, suffer from stroke during non-working hours, and reside in rural areas were significantly higher in the PHD group than in the non‑PHD group, while the admission NIHSS score was lower in the PHD group (all P<0.05). Multivariate logistic regression showed that failure to call 120 (OR=1.873), insufficient stroke knowledge (OR=2.345), lack of family accompaniment at symptom onset (OR=2.781), stroke occurrence during non-working hours (OR=2.089), and rural residence (OR=2.217) were independent influencing factors for PHD (all P<0.05). The overall PAF for the five modifiable factors was 38.614 (95% CI: 26.410%-51.705%). Based on PAF ranking, the most significant contributors were insufficient stroke knowledge, failure to call 120, lack of family accompaniment, rural residence, and stroke occurrence during non-working hours. Sensitivity analysis, with PHD thresholds adjusted to 3.0 and 6.0 h, revealed no substantial change in the ranking of PAF contributors. Conclusion These five factors are independent modifiable risk factors for PHD among AIS patients. Insufficient stroke knowledge and failure to call 120 were identified as core population-level targets for prevention.
