Abstract 16857: Design and Implementation of a Prehospital Electrocardiogram Remote Transmission and Data Recording App for Acute Myocardial Infarction Based on WeChat in China
Introduction: There were evidences showing prehospital electrocardiogram (ECG) remote transmission could reduce door-to-balloon (D2B) time in ST-segment elevation myocardial infarction (STEMI) care. There is spacious room for improvement due to low ratio of tele-ECG transmission usage in China. Meanwhile, the collection of prehospital clinical data, especially key time points during emergency care is not sufficient. The existing systems for ECG transmission require unique hardware leading to poor cost-benefits. We designed a mobile app to solve these problems based on WeChat, the most popular messaging communication app in China, which can transmit clear images of high quality and has a monthly-active-user of 549 million.
Hypothesis: We assessed the hypothesis that such an app could solve the problems above in China.
Methods: Firstly, we included 192 PCI hospitals together with their global positioning system (GPS) coordinates and telephone numbers into the database throughout China. Once an ECG image is sent through the app, ECG image, transmission time and sender’s GPS coordinates will be automatically recorded onto the server; the app will reply with a multimedia message listing nearby PCI hospitals, which can be contacted by clicking the specific link easily. At the same time, the on-call physician in the PCI hospital will receive a short message containing the ECG. Furthermore, an automatically generated electronic form evaluating prehospital treatment delay is also provided, in which the key time points can be recorded by clicking.
Results: We performed a field test for a STEMI case, it took 20 seconds sending ECG and feedback message was received in 2 seconds, the responding physician in the PCI hospital stated ECG image was clear enough to interpret and all key time points were traceable. A pilot study is being conducted in a regional network including 4 PCI hospitals and 13 non-PCI hospitals in Tianjin.
Conclusions: In conclusion, this is a low cost novel digital system integrated with daily communication service app on prehospital emergency care for STEMI to solve the problems of prehospital ECG remote transmission and prehospital clinical data recording in China. The effect on D2B time and outcomes requires further study.
