Objective To investigate the influencing factors associated with delayed time in pre-hospital emergency medical care in patients with hypertensive emergency in the main urban area of Chongqing.
Methods A total of 1 246 patients with hypertension in the main urban area of Chongqing from March 2018 to August 2021 were included in this study. The delayed time in the pre-hospital emergency medical care was determined. A multivariate linear regression model was used to analyze the influencing factors.
Results The delayed time in the pre-hospital emergency medical care for the patients with hypertensive emergency was concentrated in 0‒12 h， with the average of （5.89±1.96） h. The delayed time differed significantly by gender， age， history of atrial fibrillation， diabetes， educational level， time of onset， mode of transportation， awareness of hypertensive emergency， blood pressure at the onset， and presence of persons at the onset of emergency （P<0.05）. Multivariate linear regression analysis showed that educational level， time of onset， blood pressure at the onset， awareness of hypertensive emergency， presence of persons at the onset were linearly correlated with delayed time in the pre-hospital medical care for hypertensive emergencies （P<0.05）.
Conclusion Delay in pre-hospital medical care is prevalent for patients with hypertensive emergency in the main urban area of Chongqing. The delayed time is associated with multiple factors， such as educational level， time of onset， blood pressure at onset， awareness of hypertensive emergency， and presence of persons at onset. It warrants further improvement in the interventions to reduce the delay in the pre-hospital medical care.
