Prehospital Interventions: On-scene-Time and Ambulance-Technicians' Experience

Abstract

Introduction:Very little evidence is available on the experience of ambulance-personnels or on the impact of prehospital interventions on total prehospital time.Hypothesis:On-scene-time increases with the number of prehospital techniques used, and ambulance-technicians achieve only limited clinical experience in prehospital techniques.Methods:Prospective, observational registry study including 56 ambulance technicians from two ambulance stations in the mixed urban/rural county and 5,557 patients who were brought to a hospital in 1998. The number of cases in which each ambulance-technician performed various kinds of prehospital techniques, and the average on-scene time for each prehospital technique and several combinations of prehospital techniques were calculated.Results:There were large differences between the number of times each technique was used. On-scene time was smallest when no techniques were used and tended to increase with the number of interventions used. On-scene-time was relatively low for patients with cardiac arrest.Conclusion:The Danish ambulance-technicians' curriculum includes interventions for which the technicians only achieve limited practical experience. Prehospital interventions are associated with an increase of on-scene time.

Prehospital versus Emergency Room Intubation of Trauma Patients in Qatar: A-2-year Observational Study

“…Earlier reports have demonstrated that on-scene time is influenced by injury severity and EMS interventions. [363738] Over a 17-year period, Wyen et al ,[39] reported 16 variables that had significant impact on the on-scene-treatment time. Of these variables; intubation, car occupant, HEMS, volume administration, sedation, open fracture and establishing chest tubes were important determinants of on-scene-treatment time.…”

Is preoperative period associated with severity and unexpected death of injured patients needing emergency trauma surgery?

“…This study showed prehospital times of 48.2±23.6 min, while a US meta-analysis of trauma patients [14] showed prehospital times of 43.17 min in rural areas, 30.97 min suburban areas, and 30.96 min in urban areas. Several studies [15][16][17][18] found that a decrease in prehospital time resulted in improved patient survival. Medical administrative approaches are needed to expand the trauma transportation system in Japan and reduce prehospital time.…”

“…1 Abb. 2 9 Verteilung der Notarzteinsätze nach der NACA-Einstufung Ein Schwachpunkt unserer Untersuchung ist, dass nicht zwischen "vom Hubschrauberarzt selbst" vs. "von bodengebunden tätigen Notärzten" versorgten Patienten unterschieden werden kann.…”

“…Es ist mehrfach beschrieben worden, dass der präklinische Behandlungserfolg in großem Maß von der Erfahrung in der Anwendung abhängt [1,6,9,20,21]. Man muss allerdings zu bedenken geben, dass in der Notfallmedizin kaum strenge Empfehlungen zu bestimmten Akutinterventionen existieren.…”
