Regional intensive care transports: a prospective analysis of distance, time and cost for road, helicopter and fixed-wing ambulances

Abstract

BackgroundThere are three different types of ambulance systems, all of which can manage the same secondary intensive care patient transport mission: road ambulance, rotor-wing ambulance, and fixed-wing ambulance. We hypothesized that costs for specific transport distances would differ between systems. We aimed to analyze distances and observed times for ambulance intensive care secondary transport missions together with system costs to assess this.MethodsWe prospectively collected data for consecutive urgent intensive care transports into the regional tertiary care hospital in the northern region of Sweden. Distances and transport times were gathered, and a cost model was generated based on these together with fixed and operating costs from the three different ambulance systems. Distance-cost and time–cost estimations were then generated for each transport system.ResultsRoad ambulance cost relatively less for shorter distances (within 250 kilometers/155 miles) but were relatively time ineffective. The rotor-wing systems were most expensive regardless of distance; but were most time-effective up to 400–500 km (248–310 miles). Fixed-wing systems were more cost-effective for longer distance (300 km/186 miles), and time effective for transports over 500 km (310 miles).ConclusionsIn summary, based on an economic model developed from observed regional ICU patient transports, and cost estimations, different ambulance system cost-distances could be compared. Distance-cost and time results show that helicopters can be effective up to moderate ICU transport distances (400–500), though are expensive to operate. For longer ICU patient transports, fixed-wing transport systems are both cost and time effective compared to helicopter-based systems.

Non-technical skills evaluation in the critical care air ambulance environment: introduction of an adapted rating instrument - an observational study

“…The air ambulance environment is a complex and dynamic health-care setting, where clinicians work with limited resources to provide very advanced levels of care [ 8 – 10 ]. Highly specialised care is centralised in many modern health care systems and critically ill patients are routinely transported large distances to tertiary hospitals to provide timely access to intensive care [ 11 , 12 ]. Air ambulance transport teams tend to be small and comprise different professional categories such as nurses, emergency medical technicians, and physicians.…”

Impaired oxygenation and hemodynamic instability are independent predictors of long-term mortality in a regional cohort needing urgent fixed-wing intensive care transport to tertiary care

“…For longer distance transports, xed-wing ambulance systems are more cost-effective than helicopter emergency medical systems. (1) Inter-hospital critical care transports in northern Sweden are carried out by specialized teams of anesthesiology/intensive care physicians and nurses, and the…”

Issues to resolve with the use of extracorporeal membrane oxygenation during interfacility transportation

“…La elección de uno u otro medio depende de muchas variables: distancias a recorrer, orografía del terreno, nivel de carreteras, estructuras hospitalarias, meteorología dominante en la región y disponibilidad de medios de transporte adecuados con la tecnología adecuada (33,56,57). Las recomendaciones sobre el transporte a utilizar son muy variables, en las guías inglesas de transporte crítico, recomiendan considerar el traslado con helicóptero para distancias por encima de los 80 km y avión medicalizado por encima de los 240 km (57), mientras que las guías ELSO recomiendan el transporte terrestre hasta 300 km, helicóptero hasta 600 km y avión por encima de estas cifras (27,58). Es importante estudiar la evolución en aquellos países donde se realizan numerosos traslados de pacientes críticos y en ECMO, no evolucionando de forma similar por otros condicionantes como son la meteorología y la noche.…”
