The German approach to emergency/disaster management

Disaster control and disaster relief in Germany are public tasks. But the government has shifted the responsibility of the administration of these tasks to the 16 states, the so called "Lander", because the EFG is a federal republic. The same is valid for the civil defense and the civil protection in the case of military or international risks. The 16 states are also responsible for the legislation of rescue service, fire fighting service and disaster control (natural and technical disasters). Counties and district-free cities are responsible for the organisation of these services. The German system is based on the principle of subsidiary between official and private institutions. A lot of official and private relief organisations are responsible for the execution of disaster relief tasks. In Germany the following organisations exist: Official (GO): Technisches Hilfswerk (THW/Federal Technical Support Service), Feuerwehren (Fire Brigades/professionals and volunteers) Academie of Emergency Planning and Civil Defense Private (NGO): Arbeiter-Samariter-Bund Deutschland (ASB/Workers' Samaritan Association Germany), Deutsche Gesellschaft zur Rettung Schiffbruchiger (DGzRS, German Lifesaving Association), Deutsches Rotes Kreuz (DRK/German Red Cross), Johanniter-Unfall-Hilfe (JUH/St. John's Ambulance), Malteser Hilfsdienst (MEID/Maltese-Relief-Organisation). ASB, DRK, JUH and MHD are specialised in the field of rescue, medical and welfare services and medical disaster relief. 80% of the German rescue service and 95% of the German disaster medical relief are realised by these NGO's. NGO's and GO's employ more than 1.2 million volunteers and appr. 100,000 professionals. Rescue service is carried out by professionals, disaster relief by volunteers. The German constitution allows to call the federal army in case of disaster, to support the disaster relief organisations (for example: flood Oder River 1997, train-crash "ICE" 1998). In all counties and district free cities disaster control staffs are set up by the administration. During disaster relief operations a operational command is on site. Most of the counties and district free cities, medical executives, rescue staff executives along with fire executive officers are responsible for the medical rescue organisation. All emergency physicians and medical executives have attended special training or a 520 hours-training-course (Paramedics). All volunteers of the medical service in the disaster relief organisations are trained in separate special courses (90 hours). Over the last years, civil protection, disaster relief and rescue services in the FRG have been reorganised. In 1997, the civil protection was reformed by a new federal act. Disaster relief of the "Lander" is supported by Federal Government with about 9000 vehicles and a budget for training. Emergency physicians have to take part in a (80) eighty hours lasting course on emergency medicine from an interdisciplinary point of view; they are only allowed to do rescue missions after having proved basic experience in emergency medicine as well as having completed a (18) eighteen-months-postgraduate training period at least. Senior emergency physicians receive and additional (40) forty-hours-lasting theoretical and practical training-after three years practice in rescue services as a minimum. There are special training courses offered for Medical and Non-Medical Personal to cope with disaster situation by different institutions and organisations.

Detection and identification of fungal pathogens in blood by using molecular probes

A PCR assay was developed for the detection and identification of Candida and Aspergillus species. The design of the oligonucleotide primer pair as well as the species-specific probes used for species identification was derived from a comparison of the sequences of the 18S rRNA genes of various fungal pathogens. The primers targeted a consensus sequence for a variety of fungal pathogens. The assay was tested for sensitivity and specificity with 134 fungal and 85 nonfungal isolates. To assess clinical applicability, 601 blood samples from four defined groups were tested: group A (n = 35), controls; groups B to D (n = 86), patients with febrile neutropenia, without fungal colonization (group B; n = 29) and with fungal colonization (group C; n = 36); and patients with documented invasive fungal infection (IFI) (group D; n = 21). The assay detected and, by species-specific hybridization, identified most of the clinically relevant Candida and Aspergillus species at 1 CFU/ml of blood. Amplification was 100% sensitive for all molds and yeasts tested, with Histoplasma capsulatum being the only non-Aspergillus species hybridizing with the Aspergillus spp. probe. None of 35 group A patients and only 3 of 65 group B and C patients were PCR positive. The sensitivity of the assay for specimens from patients with IFI (21 patients in group D) was 100% if two specimens were tested. For specificity, 3 of 189 specimens from patients at risk but with negative cultures were positive by the assay, for a specificity of 98%. PCR preceded radiological signs by a median of 4 days (range, 4 to 7 days) for 12 of 17 patients with hepatosplenic candidiasis or pulmonary aspergillosis. For the 10 patients with IFI responding to antifungal therapy, PCR assays became persistently negative after 14 days of treatment, in contrast to the case for 11 patients, who remained PCR positive while not responding to antifungal therapy. Thus, the described PCR assay allows for the highly sensitive and specific detection and identification of fungal pathogens in vitro and in vivo. Preliminary data from the screening of a selected group of patients revealed some value in the early diagnosis and monitoring of antifungal therapy.

[Cardiovascular complications in hypertensive patients during the peroperative phase]

Circulatory complications during the intraoperative and postoperative phases were evaluated in a prospective study on the effectivity of different modes of treatment of hypertonics. 151 patients were subdivided into four groups: Group 1: Treated hypertension, blood pressure normal Group 2: Treated hypertension, blood pressure levels above 160 mmHg Group 3: Untreated hypertension or treatment of hypertension discontinued Group 4: Patients with threshold hypertension. The results show that patients treated inadequately or for a short period only, had the highest complication rates. On the whole, more than 36% of the patients treated inadequately (group 2) during the intraoperative and postoperative periods, had complications of the cardiovascular system, whereas in the untreated patients (group 3) the rate of complications was 30%. Patients with a normal blood pressure (group 1) and with threshold hypertension (group 4), on the other hand, showed a markedly lower incidence of complications, namely, 16%. These results suggest that it would be advisable to effect a consistent preoperative treatment, thus lowering the involved risk. On no account should any possible difficulties in organizing such treatment result in discontinuance of treatment of in-non-treatment.
