허혈성 뇌졸중 환자의 응급실 도착시간에 영향을 미치는 요인

Abstract

The purpose of this study was to identify the factors influencing the time from the stroke symptom onset to emergency department arrival (time-to-ED after onset). Participants in this study were ischemic stroke and transient ischemic attack patients who admitted to Jeju National University Hospital. Data were collected from August, 2013 to June, 2014. Medical records and structured questionnaire by face-to-face interview were used to assess the participants' general and stroke-related characteristics, stroke-related knowledge and time-to-ED after onset. The data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient and Stepwise multiple regression with SAS 9.2 version.

The results of this study were as follows: 1. The mean of time-to-ED after onset was 19.82±35.37 hours and the mean score of 9.77±3.17 (range, 0-15) on the stroke-related knowledge and 38.4% of subjects were presented in emergency department within 3 hours after symptom onset. 2. There were statistically significant differences in time-to-ED after onset according to previous education about stroke (t=4.08, p<.001), mode of transportation (F=5.32, p=.001). 3. There were statistically significant negative correlations between time-to-ED after onset and stroke-related knowledge(r=-.33, p=.005). 4. The factor affecting time-to-ED after onset was stroke-related knowledge. The factor explained 9.5% of time-to-ED after onset.

Prompt arriving at emergency department after onset of stroke is essential for patients' survival. Stroke-related knowledge was found to be the affecting factor on time-to-ED after onset. For early emergency department arrival, it is necessary to develop and implement the program for increasing stroke-related knowledge.
