Telemedicine at the Emergency Site – Evaluated by emergency team members in simulated scenarios
(2015)
The hypothesis of this study states that emergency medicine can benefit from telemedicine, whenever paramedics at a remote emergency site request consultation or mentoring by a distant emergency doctor. The hypothesis was semi-qualitatively evaluated in accordance with the protocol of the EU project in the setting of a medical simulation centre. Paramedics encountered simulated standardized emergency case scenarios, connected for teleconsultation and telementoring with emergency doctors by video and audio link through a newly developed real-time HD-video system called LiveCity camera. Paramedics and emergency doctors regarded the simulated scenarios as realistic and relevant and took the simulation seriously. Thus,the following conclusions can be drawn: 1.) Emergency team members encounter situations at the emergency site, in which they would like to get help by a more experienced colleague, especially help with diagnostics and treatment. 2.) The telemedical contact to an emergency doctor makes paramedics feel confirmed in their work, more secure, even in legal aspects. Paramedics do not feel controlled by telemedicine or like a puppet on a string. Their relationship to the patient is not mainly deranged or interfered by the doctor and their course of action is not mainly disrupted. The tele-emergency doctors do not feel like puppet masters and continue feeling as doctors and do not perceive themselves as interferer within the emergency team. 3.) Emergency team members call for a telemedical system providing transmission of vital signs as well as audio- and video-connection. 4.) The LiveCity camera is an effective telemedical tool. The audio quality is good and the orientation on the screen is easy. Paramedics state, that filming the emergency site is easy, does not restrict the field of vision and paramedics can communicate the emergency doctors everything they want to show and tell. Thus the emergency doctors get additional information. While the LiveCity camera is mostly perceived as not too heavy, the LiveCity camera is not easy to operate, very failure-prone and can derange the communication among team members at the emergency site. Nevertheless, the LiveCity camera is not perceived as an additional burden. 5.) Telemedicine is predominantly and largely appreciated by the members of the emergency team. Connecting the tele-emergency doctor to the remote paramedics leads to a perceived faster start of the therapy and is considered as helpful, improving the situation and the quality of patient care. The adherence to medical guidelines and therefore the quality increased, when the paramedics were connected to an emergency doctor through the telemedicine connection. In general, the quality of diagnostics, the correctness of diagnosis and the quality of therapy were rated higher. The majority of paramedics would call a tele-emergency doctor in cases, they wouldn´t normally activate medical support. The emergency team members largely agree in perceiving the tele-emergency doctor system as useful, and they can imagine, working in a tele-emergency system. As a conclusion, the general hypothesis of this study is mainly and in many items supported: Emergency medicine benefits from telemedical support via video- and audio link as studied here with a newly developed real-time HD-video system called LiveCity camera, whenever paramedics at a remote emergency site request consultation or mentoring by a distant emergency doctor.
Ziel dieser Arbeit ist es, die Problematik des steigenden Qualitätsanspruchs und des Kostendrucks im Gesundheitssystem aufzugreifen und vor diesem Hintergrund zwei entscheidende Prozesse im Krankenhaus, die Poliklinik als ambulante medizinische Einheit und die Station als stationäre Pflegeeinheit, näher zu untersuchen. Derzeit sind diese beiden Einheiten noch weitgehend unabhängig voneinander bzw. sie sind im Behandlungsprozess hintereinandergeschaltet. Die Effizienz und die Wirksamkeit von Gesundheitsleistungen hängen maßgeblich von der Entwicklung der Arbeitsteilung und vom Zusammenspiel des ambulanten und des stationären Sektors ab. Im Rahmen dieser Arbeit sollen diese organisch gewachsenen Organisationsstrukturen nun aufgebrochen werden. Es findet ein Perspektivenwechsel von traditionellen Strukturen zu einer prozessualen Sichtweise statt. Anhand verschiedener Prozessoptimierungsansätze soll der Prozess der stationären Versorgung auf der Station in den Prozess der Versorgung in der Poliklinik teilweise integriert werden. Ein zentraler Punkt ist dabei die Identifizierung und Bewertung von Synergiepotenzialen durch die Bündelung bzw. durch die Verlagerung der Ressourcen Pflegepersonal und ärztliches Personal. Neben den quantifizierbaren Folgen für den Ressourceneinsatz sollen durch die Neugestaltung der Prozesse auch Verbesserungen in den medizinischen Behandlungsabläufen und in der Qualitätssicherung erreicht werden. Ein Kerngedanke für die Prozessoptimierung ist eine Klassifikation des Prozessobjektes Patient in mobile und immobile stationäre Patienten. Anhand einer Simulation mit dem Programm MedModel werden die Prozessveränderungen im Ist- und Sollzustand ausgewertet und verglichen. Der Erfolg der angestrebten Prozessoptimierung wird an den Dimensionen der Prozessleistungsfähigkeit Kosten, Qualität und Zeit gemessen.
