[Advanced medical post within hospitals as possible tactical instrument for handling mass casualty incidents]. / Der Behandlungsplatz innerhalb eines Krankenhauses als mögliches taktisches Werkzeug zur Bewältigung eines Massenanfalls von Patienten.

BACKGROUND: An important instrument for handling mass casualty incidents in preclinical settings is the use of an advanced medical post. In certain circumstances, however, the establishment of such an advanced medical post on or close to the incident site is impossible. Terrorist attacks are a prime example for this. The highest priority for hospitals during mass casualty incidents is to adjust the treatment capacity to the acute rise in demand and to sustain its functionality throughout the duration of the incident. By establishing an advanced medical post within hospitals during certain types of mass casualty incidents these aims could potentially be accomplished. AIMS: The aims of this pilot study were to test the practicability of the establishment of an advanced medical post within a university hospital and to identify potential problems. The results provide the foundation of a generalized concept, which will then be integrated into the hospital emergency plans. METHODS: After the formation of a multiprofessional expert committee, different areas within the hospital were evaluated based on spatial and tactical considerations. Predefined questions were assessed and harmonized with respect to organization, vehicle management, communication, leadership and patient transport through the means of a practice run. RESULTS: The establishment and operation of an advanced medical post within the hospital were easily possible. The consequent deployment of section leaders enabled the smooth coordination of transport and an unobstructed simulated patient flow. The management of the treatment area by a senior emergency physician and a senior emergency medical service officer in close cooperation with the operational hospital lead proved to be a useful concept. Technical problems with communication within the hospital were resolved by using wireless phones and the installation of a digital radio repeater. DISCUSSION: During acute scenarios with only short prior notice, the authors prefer concepts that supplement the normal hospital operation through additional staff and material. In circumstances with prior notice of more than 60 min an advanced intrahospital advanced medical post, staffed by civil protection units, could be a concept that enables the absorption of the first patient arrivals within the first hour of a mass casualty incident without disturbing the functionality of hospitals to any great extent. Further practice runs are, however, necessary to further develop and adjust this concept to real-life circumstances.

[Comparison of two models of a treatment area with respect to treatment times in critically ill patients : A pilot study]. / Vergleich zweier Modelle eines Behandlungsplatzes im Hinblick auf die Versorgungszeiten kritischer Patienten : Eine Pilotstudie.

BACKGROUND: In the case of a mass casualty incident an advanced medical post (AMP) plays a central role in the medical care by ambulance service and civil protection units. Besides the traditional organization with one triage category per medical services tent, it can also be structured in a mixed form (i.e. a defined number of patients with different triage categories are assigned to each medical services tent). To date it remains unclear which organization format is better in order to rapidly evacuate those patients with the highest priority. METHODS: The Medical Task Force of Lower Franconia treated 50 identical and standardized training patients including 18 triage category red/emergency (36%), 12 triage category yellow/urgent (24%), 18 triage category green/non-urgent (36%) and 2 triage category black/dead (4%) in the course of a scheduled field exercise within two consecutive training sessions (first session: classical structure, second session: mixed structure). The training patients were represented by a dynamic patient simulation, whereby simulation cards showed injury patterns and the external appearance of the patients at a defined point which required certain interventions. The patients' conditions changed when these measures were accomplished or neglected. The length of stay of the patients with the triage category red/emergency at the AMP (start of triage to start evacuation) as well as the overall number of evacuated patients were collated and compared. RESULTS: Out of 18 patients with the triage category red/emergency, 13 patients in each session were evacuated in one pass. During the first session the mean evacuation time at the AMP was 25 min and during the second session the mean evacuation time was 18 min. After the end of the 90 min of exercise time in the first session 14 non-critical patients (triage categories yellow/urgent and green/non-urgent, n = 30) were still left at the AMP (16 evacuated) and in the second session 12 (18 evacuated). CONCLUSION: Depending on the mission requirements the mixed form of AMP organization can provide several advantages. In addition to rapid operational readiness and high flexibility the patient distribution by triage category could be processed better and the evacuation time of critical patients could be shortened.

[Telemedical prenotification in acute stroke treatment : Experiences from the Stroke Angel initiative from 2004 until the present]. / Telemedizinische Voranmeldung in der akuten Schlaganfallversorgung : Erfahrungen der Stroke-Angel-Initiative von 2004 bis heute.

OBJECTIVE: The Stroke Angel initiative investigates the implementation of telemedicine for improvement of preclinical communication between emergency medical services (EMS) and stroke units in cases of acute stroke. MATERIAL AND METHODS: Stroke Angel is a technical system for the telemedical prenotification of patients in cases of suspected stroke at a stroke unit by the EMS. Within the framework of an observational study, the team has been investigating the effects of the system on door-to-computed tomography (CT) and door-to-needle times as well as the lysis rate in the neighboring regions of Rhön-Grabfeld and Bad Kissingen since 2005. RESULTS: The system supports the acute treatment of neurological emergencies and functions as a catalyst for the interlinking of medical institutions in the region as well as for communication between emergency physicians/EMS and hospital physicians. The use of a computer-based data collection enables a continuous improvement process leading to an acceleration of internal clinical procedures and an increase of the lysis rate with the mortality rate staying constant. CONCLUSION: Telemedicine is applicable in the preclinical care of acute stroke and, thanks to the computer-based data collection, leads to an increase in process transparency, which helps to improve the internal clinical processes in and around a stroke unit.

[Mobile computing systems in preclinical care of stroke. Results of the Stroke Angel initiative within the BMBF project PerCoMed]. / Einsatz mobiler Computing-Systeme in der präklinischen Schlaganfallversorgung. Ergebnisse aus der Stroke-Angel-Initiative im Rahmen des BMBF-Projekts PerCoMed.

BACKGROUND: Telemedical networks that apply innovative mobile information technologies (IT) are an innovative approach to improve stroke care in community settings. Within the German Stroke Angel initiative and the research project PerCoMed (Pervasive Computing in Medical Care, funded by the Federal Ministry of Education and Research, http://www.percomed.de) the effects of such a solution were assessed by an interdisciplinary research approach. The main goal of the team of researchers and practitioners was to provide clear evidence of improvements in intersectional processes of the stroke chain survival, namely in the acute stroke processes between prehospital rescue services and hospital stroke units. MATERIAL AND METHODS: Between October 2005 and October 2007 the paramedical staff of five rescue service transporters in a rural area of northern Bavaria was included in a network with the stroke unit of the Neurological Clinic Bad Neustadt. Telemedical support by the Stroke Angel computing system - a software running on a personal digital assistant (PDA) to transmit patient data from the rescue team to the hospital during patient transporting time - was established. As procedural guidance, the Stroke Angel system suggests a predefined path through the necessary emergency procedures according to the structure of the mandatory protocol and the implemented Los Angeles Prehospital Stroke Screen (LAPSS). RESULTS: In the empirical study the authors obtained a complete data set of 226 consecutively admitted patients for analysis in Bad Neustadt and LAPSS data of 217 patients from a second scenario in Düsseldorf. Medical, economic and technical analyses were applied. The technological robustness of the Stroke Angel system could be proven and information entered was transmitted fully and correctly. Concerning medical research questions, for both scenario locations LAPSS with a sensitivity of 68.3% and a specificity of 85.1% has to be deemed insufficient. Hence, alternative algorithms will have to be used in the next steps of evaluation. The system significantly influenced the clinical process of acute stroke management more than the preclinical ones (door-to-CT: 32 min. before and 16 min. at the end of the project). Lysis treatment rose from 6.12% (2005) to 11.17% (2007) of patients with acute stroke. CONCLUSIONS: From the set of perspectives taken, the study illustrates that mobile computing technologies offer new and innovative approaches to improve intersectional acute stroke care. It also teaches the participants that interdisciplinary research can significantly deepen the understanding of such technologies and projects, which can lead to better decision making concerning solution implementation, management and improvements. The approach will be brought into daily practice in Bad Neustadt/Saale within the next months.

[Acute treatment of patients after a stroke. From the incident site to the stroke unit]. / Akutversorgung des Patienten mit Schlaganfall. Vom Einsatzort bis zur "stroke unit".

Strokes are the third most common cause of mortality in western countries and the main cause of long-term invalidation. Systemic intravenous thrombolysis is the current therapeutical choice in acute stroke within 3 h after clinical onset but new pharmacological developments will have the potential to expand the time window for 6 h or more. To safeguard this option and for optimal treatment of stroke patients, better preclinical structures are necessary. A stroke is an extremely urgent case and emergency rescue services must treat this situation in a similar manner to polytrauma or cardiac arrest. Rescue services will need more training and knowledge in basic neurological examination and standard acute therapy, including maintaining sufficient oxidation of the brain, therapy of possible cardiac arrhythmias, blood pressure management, blood sugar disturbances and hyperthermia. Prior announcement of patients in the admitting hospital is desirable.
