Analysis of Time to the Hospital and Ambulance Use Following a Stroke Community Education Intervention in China

Abstract

Importance: Prehospital delay (time from symptom onset of stroke to the door of a hospital) in patients with stroke is long in China. With the goal of improving public awareness and knowledge of stroke recognition, Stroke 1-2-0 was developed in China as an education program to prompt rapid response to the onset of stroke based on clinical practice in China, and examination of its outcomes is needed. Objective: To investigate the association of the Stroke 1-2-0 educational campaign with prehospital delay for patients with ischemic stroke. Design, Setting, and Participants: In a population-based cross-sectional study, all patients with ischemic stroke events were admitted to the Minhang Hospital, which is the only tertiary care hospital with a stroke center that provides acute stroke care in Xinzhuang county, Shanghai, China. The study period was from January 1, 2016, to December 31, 2019, and data analysis was performed from January 1 to July 31, 2021. Exposures: A multifaceted Stroke 1-2-0 educational campaign comprising slides, videos, brochures, and posters distributed in the community. Main Outcomes and Measures: Proportion of patients with hospital arrival within 3 hours and use of an ambulance to seek medical care, as well as the odds of seeking medical attention within 3 hours after the stroke before vs after initiation of the multifaceted educational campaign. Results: A total of 2857 patients (1774 men [62.1%]; mean [SD] age, 69.83 [12.66] years) with stroke were identified, including 503 in the precampaign period and 2354 in the postcampaign period. Following the multifaceted campaign, the median (IQR) prehospital delay time decreased from 18.72 (7.44-27.84) hours to 6.00 (2.00-16.35) hours (P
