A Single Centre Retrospective Analysis of Door to Balloon Times With Prehospital Notification in STEMI With New Smartphone Application (CORPULS) vs Email/SMS Based System (LIFENET)

ST elevation myocardial infarction (STEMI) requires effective pre-hospital communication to ensure excellent patient outcomes. Recently, NSW rolled out a new pre-hospital notification system for STEMI – CORPULS, a new app based pre-hospital notification system compared to the previous email/phone based system LIFENET. To ensure the implementation of a new app based system did not impact on door to balloon times (DBTs) of STEMI patients, a retrospective audit was performed. Method A retrospective audit of patients presenting to a single metropolitan centre for Primary PCI with pre-hospital notification were included for 18 months prior to the changeover utilising the old LIFENET system compared to the first 18 months with the new CORPULS system. Analysis was then performed comparing DBTs between groups. Results A total of 153 patients were included. There was no statistically significant difference in DBTs between the groups; both in hours and out of hours (combined 43.5 min vs 43 min (p=0.9732) out-of-hours 56.8 min vs 54.2 min (p=0.5294), in hours 25 min vs 31 min (p=0.3534) ( Table, Figure ). Conclusion Overall, there was no significant difference in door to balloon times between the new CORPULS pre-hospital notification system and the previous LIFENET system. | Lifenet median door to balloon time (mins) (IQR) | | Corpuls median door to balloon time (mins) (IQR) | U Statistic | p-value | | --- | --- | --- | --- | --- | | Combined | 43.5 (27.0–59.0) | 43.0 (32.0–56.0) | 2,402.5 | 0.9732 | | In-hours | 25.0 (20.2–33.2) | 31.0 (22.5–36.0) | 333.5 | 0.3534 | | Out-of-hours | 56.8 (44.2–65.8) | 54.2 (42.2–64.2) | 919.5 | 0.5294 |
