Stroke burden in China has increased over the past 30 years, and remains particularly high in rural areas. There is a north-to-south gradient in stroke in China, with the greatest stroke burden observed in the northern and central regions.

This study aimed to explore pre-hospital delay and its associated factors in first-ever stroke registered in communities from three cities in China. The rates of delay greater than or equal to 2 hours were calculated and factors associated with delays were determined by non-conditional binary logistic regression, after adjusting for different explanatory factors. Among the 403 cases of stroke with an accurate documented time of prehospital delay, the median time (interquartile range) was 4.00 (1.50–14.00) hours. Among the 544 cases of stroke with an estimated time range of prehospital delay, 24.8% of patients were transferred to the emergency department or hospital within 2 hours, only 16.9% of patients with stroke were aware that the initial symptom represented a stroke, only 18.8% used the emergency medical service and one-third of the stroke cases were not identified by ambulance doctors. In the multivariate analyses, 8 variables or sub-variables were identified. In conclusion, prehospital delay of stroke was common in communities. Thus, intervention measures in communities should focus on education about the early identification of stroke and appropriate emergency medical service (EMS) use, as well as the development of organized stroke care.

IntroductionThere is a downward trend of stroke-related mortality in the USA. By reviewing all published articles on stroke mortality in China, we analysed its trend and possible factors that have influenced the trend.MethodsBoth English and Chinese literatures were searched on the mortality of stroke or cerebrovascular diseases in China. Potential papers related to this topic were identified from PubMed, Medline, Embase, Cochrane Library, Wanfang Database, SINOMED and China National Knowledge Infrastructure databases.ResultsComparing the results from the most recent population-based epidemiological survey and databank from the national Center for Disease Control and Prevention, the age-adjusted stroke mortality rate has shown a downward trend among both urban and rural population in the past 30 years in China. Comparing with 30 years ago, the rate of stroke mortality has decreased by more than 31% in urban/suburban population and 11% in rural population. In men, the age-adjusted stroke mortality rate decreased by 18.9% and in women by 24.9% between 1994 and 2013. Factors that may have contributed to the trend of decreased stroke mortality rate include (1) improved healthcare coverage and healthcare environment; (2) improved treatment options and medical technology; (3) support by government to educate the public on stroke and stroke prevention; and (4) improved public knowledge on stroke.ConclusionsThe age-adjusted stroke mortality rate in China has shown a downward trend among both urban and rural population in the past 30 years. The major influencing factors that helped in reducing stroke mortality in China included improved healthcare coverage, healthcare environment, the updated treatment options and modern medical technology.
