“…When distances are short, a rapid response vehicle is used in Finland instead of a helicopter, partly explaining the difference compared to the systems operating only by helicopter to the longer distances. Three of the six bases in Finland are located in mostly urban areas where distances are generally short and the use of helicopter might not result in time saving [31,32]. As shown by our study, the practice of escorting a patient transported in an ambulance is more common in our system compared to other systems [6][7][8].…”

“…As shown by our study, the practice of escorting a patient transported in an ambulance is more common in our system compared to other systems [6][7][8]. However, several studies have demonstrated benefit from timesaving by helicopter transportation in select patient groups [28,29,31]., raising the question whether helicopter transportation should be more frequent.…”

“…Contrary to other comparable systems where stroke and myocardial infarction are common reasons for HEMS dispatch [7,8,21]., Finnish physician-staffed HEMS units are not usually dispatched for these missions, although encounter these patients when dispatched on different criteria, such as decreased level of consciousness. There is evidence suggesting that stroke and MI patients might stand to benefit from primary dispatch of HEMS [29,31].…”

Background: Helicopter Emergency Medical Services (HEMS) play an important role in prehospital care of the critically ill. Differences in funding, crew composition, dispatch criteria and mission profile make comparison between systems challenging. Several systems incorporate databases for quality control, performance evaluation and scientific purposes. FinnHEMS database was incorporated for such purposes following the national organization of HEMS in Finland 2012. The aims of this study are to describe information recorded in the database, data collection, and operational characteristics of Finnish HEMS during 2012-2018. Methods: All dispatches of the six Finnish HEMS units recorded in the national database from 2012 to 2018 were included in this observational registry study. Five of the units are physician staffed, and all are on call 24/7. The database follows a template for uniform reporting in physician staffed pre-hospital services, exceeding the recommended variables of relevant guidelines. Results: The study included 100,482 dispatches, resulting in 33,844 (34%) patient contacts. Variables were recorded with little or no missing data. A total of 16,045 patients (16%) were escorted by HEMS to hospital, of which 2239 (2%) by helicopter. Of encountered patients 4195 (4%) were declared deceased on scene. The number of denied or cancelled dispatches was 66,638 (66%). The majority of patients were male (21,185, 63%), and the median age was 57.7 years. The median American Society of Anesthesiologists Physical Scale classification was 2 and Eastern Cooperative Oncology Group performance class 0. The most common reason for response was trauma representing 26% (8897) of the patients, followed by out-of-hospital cardiac arrest 20% (6900), acute neurological reason excluding stroke 13% (4366) and intoxication and related psychiatric conditions 10% (3318). Blunt trauma (86%, 7653) predominated in the trauma classification.

“…The greater the distance from the hospital, the more the time that can be saved. As mentioned, only a few studies that compare the slope or curves (between distance and time) of the modalities have been reported, [21,25] and to the best of our knowledge, the current result is the rst curve in Korean HEMS circumstances. Furthermore, the R 2 parameter, which refers to the goodness-of-t of the ideal curve, is higher in HEMS (0.7722 in HEMS vs. 0.6518 in GEMS).…”

IntroductionPrevious comparison studies regarding two types of transportation, helicopter (HEMS) versus ground emergency medical services (GEMS), have shown underlying heterogeneity as these options have completely different routes and consequent times with reference to one patient. To compare the two types of transportation on a case-by-case basis, we analyzed the retrospectively reviewed HEMS and predicted GEMS data using an open-source navigation software.MethodsPatients transferred by military HEMS from 2016 to 2019 were retrospectively enrolled. The HEMS records on the time of notification, injury point and destination address, and time required were reviewed. The GEMS data on distance and the predicted time required were acquired using open-source social navigation systems. Comparison analyses between the two types of transportation were conducted. Further, linear logistic regression analyses were performed on the distance and time of the two options.ResultsA total of 183 patients were enrolled. There was no statistical difference (p=0.3021) in the distance between the two types of transportation, and the HEMS time was significantly shorter than that of GEMS (61.31 vs. 116.92 minutes, p<0.001). The simple linear curves for HEMS and GEMS were separately secured, and two graphs presented the statistical significance (p) as well as reasonable goodness-of-fit (R2). In general, the HEMS graph demonstrates a more gradual slope and narrow distribution compared to that of GEMS. ConclusionIdeally, HEMS is identified as a better transportation modality because it has a shorter transportation time (56 minutes saved) and a low possibility of potential time delays (larger R2).Running tileHelicopter vs. navigation-based ground ambulance

ConclusionIdeally, HEMS is identi ed as a better transportation modality because it has a shorter transportation time (56 minutes saved) and a low possibility of potential time delays (larger R 2 ). With a strict patient selection, HEMS can rescue injured or emergent patients who are "out of the golden hour."
