| Summary: | 碩士 === 吳鳳科技大學 === 消防研究所 === 103 === Out-of-hospital cardiac arrest (OHCA) means the survival rate is low. As the level of medical technology rise and life extension, the emergency medical service becomes important recently. Emergency medical service and the quality of emergency medical technician are taken seriously. From above reasons, it is important to investigate the outcome of patient after improving the emergency medical service.
By using the retrospective study, we continuously collected data from OHCA patients from chiayi city in Taiwan from January 2010 to December 2014. We compared the quality of emergency care and investigate the outcome between designated and non-designated ambulance crews.
It showed that the scene interval (mean 8.9 minutes vs. 6.9 minutes, p<0.001) was increased for designated ambulance crews. The time transfer to hospital was lower (mean 3.1 minutes vs. 4.0 minutes, p<0.001). The ratios for using oral airway emergency tools (52.4% vs. 47.6%, p<0.001) and the usage of LMA (93.5% vs. 6.5%, p<0.001) were also statistically significantly increased for designated ambulance crews. Further, we found that the age of patient ( (Odds ratio 0.975, 95% Confidence Interval 0.955~0.996) and the usage of AED (Odds ratio 0.266, 95% Confidence Interval 0.112~0.632) are the outcome impactor. In the future, we hope this analysis results can improve the emergency medical service system.
