AbstractBackground: Interfacility transfers (IFTs) are an essential component of healthcare systems to allow movement of patients between facilities. It is essential to limit any delays in patients receiving the care they require at the receiving facility. The primary objective of this study was to assess whether IFT response time was reduced after implementation of an AutoLaunch protocol, in which an ambulance is dispatched to the sending facility prior to acceptance of the patient by the receiving facility. The secondary objective was to describe the frequency and amount of time ambulances had to stage outside the sending facility in situations where the ambulance arrived prior to the patient being accepted by the receiving facility. Methods: This was a retrospective pre-post analysis of patients undergoing IFT for services not available at the sending facility between October 1, 2018 and September 30, 2019, with the AutoLaunch protocol being implemented on March 25, 2019. IFT response time was defined as the time the transfer request was initially made to the time the ambulance arrived at the sending facility. Dispatch call logs and transport records were analyzed before and after implementation of the AutoLaunch protocol to assess for a difference in IFT response time as well as frequency and amount of time ambulances had to stage. Results: Of 1,881 IFTs analyzed, 885 (47.0%) were completed under the traditional protocol and 996 (53.0%) were completed under the AutoLaunch protocol. The median IFT response time under the traditional protocol was 27.5 minutes (interquartile range (IQR): 17.9, 43.3), compared with 19.9 minutes (IQR: 12.8, 28.2) under the AutoLaunch protocol (p < 0.01), representing a 27.6% reduction in response time, or 7.6 minutes saved. Of the 996 AutoLaunch transfers, there were 215 incidents (21.6%) in which the IFT ambulance had to stage, and the median staging time was 10.1 minutes (IQR: 4.9, 24.2). Conclusions: Implementation of our AutoLaunch protocol resulted in a significant reduction in ambulance response time for interfacility transfers. Further studies are needed to assess whether the reduction in response time is associated with improved patient outcomes for certain conditions.
