[IT Failures in Hospitals - Structures and Processes in Hospitals for Coping Cyber Attacks]. / IT-Angriffe an Kliniken.

Clinics are, by definition, part of a country's critical infrastructure. In recent years, hospitals have increasingly become the target of cyber attacks, resulting in disruptions to their functionality lasting weeks to even months. According to the "National Strategy for the Protection of Critical Infrastructures (CRITIS Strategy)", clinics are legally obligated to take preventive measures against such incidents. This involves evaluating, defining, and developing failure concepts for IT-dependent processes within a clinic to be prepared for a cyber attack. Specifically tailored emergency plans for computer system failures should be created and maintained in all IT-dependent areas of a clinic.Additionally, paper-based alternative solutions, such as request forms for diagnostic or consultation services, department-specific emergency documents, and patient documentation charts, should be kept in a readily accessible location known to staff in the respective areas. The complete restoration of a clinic's network after a cyber attack often requires extensive recovery of numerous IT systems, which may take weeks to months in some cases.If the hospital has robust plans for cyber emergency preparedness, including regular scans and real-time backups, stabilization and a quicker resumption of operations may be possible.

[Clinical Treatment after Terrorist Attacks - Structures and Processes in Hospitals for terror-related Mass Casualty Incidents]. / Klinische Versorgung bei (Terror-)Anschlägen/lebensbedrohlichen Einsatzlagen.

Due to several peculiarities the clinical treatment after terror-related mass casualty incidents (TerrorMASCAL) differs from handling a conventional MCI. For this reason, TerrorMASCAL situations should get attention as an own entity in hospitals emergency preparedness and response. Among other challenges hospitals surrounding the emergency area will have to deal with a large amount of non-triaged, non-treated and seriously harmed patients, some of them with unfamiliar and disfiguring injuries. In addition, the hospitals themselves can be endangered as a target of further terrorist attacks. Therefore, security concepts depending on the individual circumstances must be elaborated in consultation with the local police authorities.The incident's clinical management should be put in hands of specially trained in-house institutions. Operational and tactical tasks close to patients ("on site") should be separated from strategic and administrative responsibilities ("in the background"). The function of an "Emergency Operational and Medical Coordinator" (EOMC = ZONK) is installed to manage initial diagnostics and therapy for seriously injured victims by prioritization and scheduling available clinical resources.In order to structure the process of emergency admission for numerous patients a triage- and holding area as well as specific in-house treatment areas for different severities of injury should be set up. The clinical triage should follow a consistent algorithm that is based on the cABCDE approach. It is recommended that this algorithm should be defined in hospitals disaster and emergency planning.Surgical strategies concerning the treatment of terror victims might be oriented according to the principles of "tactical abbreviated surgical care" (TASC). This means that in extreme cases the initial measures have to be concerted to save as much lives as possible while accepting a reduced individual outcome.

[Hospital disaster planning in south-western Germany. A survey of 214 clinics]. / Krankenhausalarm- und -einsatzplanung in Baden-Württemberg. Eine länderspezifische Umfrage an 214 Kliniken.

Background: Due to legal regulations in Germany, public acute and emergency (A&E) hospitals-along with responsible authorities, emergency medical services, and other institutions such as the state medical associations-are committed to participate in civil protection. This participation includes the need to create and update emergency plans for external and internal crises and to take part in disaster drills. In fact, so far there is only little literature to prove whether and to what extent hospitals fulfill their obligations on this topic. Objectives: Using a standardized survey, the state of emergency planning in hospitals in Baden-Wuerttemberg was evaluated. Materials and methods: Based on a listing provided by the Hospital Society of Baden-Wuerttemberg (BWKG), all 214 hospitals in Baden-Wuerttemberg were identified. The standardized questionnaire inquired about specific characteristics of the emergency plan, the availability and knowledge of this plan by the hospital workforce and other local institutions that take part in civil protection and, finally, participation in disaster drills were queried. Results: Of the 214 hospitals in Baden-Wuerttemberg, 135 (63%) provided information using the questionnaire. Except for one hospital, all other clinics indicated having a special emergency plan ready. In most cases (79.3%), both external (e.g., mass casualty incidents) and internal (e.g., fire, failure of technical equipment) crises are covered. In the vast majority of cases (94%), the hospitals also indicated that they regularly update their emergency plan, whereby the frequency of updates varied markedly. Three quarters of the hospitals said that they also regularly simulate the use of the emergency plan in disaster drills. In two thirds of the cases, external forces such as emergency medical services or the fire department also take part in these drills along with the hospitals themselves. In some cases, knowledge gained from the drills was incorporated into the emergency plan or led to improvements in staff training. Conclusions: The willingness of public hospitals to establish comprehensive disaster planning and to take part in related drills seems to have improved noticeably in recent years. However, there is still the need for improvement in keeping the concepts up to date at some hospitals. Especially smaller hospitals showed deficits in emergency planning, particularly concerning preparedness for internal crises, resulting from failure of technical equipment. More regular drills should be used to test existing concepts and to familiarize employees with the processes on a routine basis.

[Managing the pandemic-relocation concept for COVID-19 intensive care patients and non-COVID-19 intensive care patients in Baden-Württemberg]. / Die Pandemie bewältigen ­ Verlegungskonzept von COVID-19-Intensivpatienten und Non-COVID-19-Intensivpatienten in Baden-Württemberg.

BACKGROUND: A sharp rise in COVID-19 infections threatened to lead to a local overload of intensive care units in autumn 2020. To prevent this scenario a nationwide relocation concept was developed. METHODS: For the development of the concept publicly available infection rates of the leading infection authority in Germany were used. Within this concept six medical care regions (clusters) were designed around a center of maximum intensive care (ECMO option) based on the number of intensive care beds per 100,000 inhabitants. The concept describes the management structure including a structural chart, the individual tasks, the organization and the cluster assignment of the clinics. The transfers of intensive care patients within and between the clusters were recorded from 11 December 2020 to 31 January 2021. RESULT: In Germany and Baden-Württemberg, 1.5% of patients newly infected with SARS-CoV­2 required intensive care treatment in mid-December 2020. With a 7-day incidence of 192 new infections in Germany, the hospitalization rate was 10% and 28-35% of the intensive care beds were occupied by COVID-19 patients. Only 16.8% of the intensive care beds were still available, in contrast to 35% in June 2020. The developed relocation concept has been in use in Baden-Württemberg starting from 10 December 2020. From then until 7 February 2021, a median of 24 ± 5/54 intensive care patients were transferred within the individual clusters, in total 154 intensive care patients. Between the clusters, a minimum of 1 and a maximum of 15 (median 12.5) patients were transferred, 21 intensive care patients were transferred to other federal states and 21 intensive care patients were admitted from these states. The total number of intensive care patients transferred was 261. CONCLUSION: If the number of infections with SARS-CoV­2 increases, a nationwide relocation concept for COVID-19 intensive care patients and non-COVID-19 intensive care patients should be installed at an early stage in order not to overwhelm the capacities of hospitals. Supply regions around a leading clinic with maximum intensive care options are to be defined with a central management that organizes the necessary relocations in cooperation with regional and superregional rescue service control centers. With this concept and the intensive care transports carried out, it was possible to effectively prevent the overload of individual clinics with COVID-19 patients in Baden-Württemberg. Due to that an almost unchanged number of patients requiring regular intensive care could be treated.

[Assessment of the risk of infection from SARS-CoV-2 for healthcare workers-findings from practice]. / Beurteilung des Infektionsrisikos durch SARS-CoV-2 für medizinisches Personal ­ Erkenntnisse aus der Praxis.

SARS-CoV­2 has rapidly spread over the world in a pandemic manner causing an infection of predominantly pulmonary manifestation named the COVID-19 disease. Currently, there is neither an effective vaccination nor a specific therapy available. At least two vaccines will be available at the time of publication. In the international press, the risk for medical personnel of SARS-CoV­2 is rated as high. The Robert Koch Institute, Germany's leading epidemiological authority, regards the risk of infection for the general population to be high. The aim of this article is to discuss and reassess the risk of infection and disease for healthcare workers based on practical experience, national regulations and guidelines, and the number of infections. Both unprotected healthcare workers and healthcare workers equipped with personal protective equipment (PPE) are considered. A corresponding risk matrix is created.The risk of infection with SAR-CoV­2 for healthcare workers is comparable to the general population and rated as high. Proper use of PPE reduces this risk to medium. PPE consists of liquid-proof gowns, gloves, and filtering face pieces (FFP; FFP 2 as a standard, FFP 3 for aerosol-releasing interventions), a hair cover, and protective goggles. Improper use of PPE, inadequate hygienic measures, and long working shifts increase the risk of infection.

Electroconvulsive therapy in patients with diagnoses other than major depression and/or difficult characteristics: a combined psychiatric-anesthesiological approach based on a retrospective chart analysis.

Though electroconvulsive therapy (ECT) requires a close cooperation between anesthesiology and psychiatry, literature lacks of approaches that consider both disciplines in parallel. Special problems might be posed by patients with complicated features or ECT-indications other than treatment-refractory depression (TRD). Considering these patients there is a particular paucity of data, especially regarding anesthesiological aspects. Therefore, we sought (1) to discuss special issues of the peri-interventional management of non-TRD-cases from a combined psychiatric-anesthesiological point of view and (2) to assess the efficacy of ECT in the classical indication of TRD as compared to cases undergoing ECT for other indications or under difficult conditions (non-TRD) by means of Clinical Global Impression-Improvement (CGI-I) scale scores. A retrospective chart analysis of patients treated with ECT between the years 2009 and 2011 at the University of Ulm, Department of Psychiatry, was conducted. Special anesthesiological efforts were necessary in cohort non-TRD. There was no difference in the clinical outcome between cohort non-TRD (n=7) and TRD (n=22) with a median CGI-I score of 2 ("much improved") in both groups. Close cooperation between psychiatry and anesthesiology is indispensable in non-TRD patients. Our results provide preliminary evidence that ECT is equally effective in the standard indication of TRD compared to other indications.

Medical student disaster medicine education: the development of an educational resource.

BACKGROUND: Disaster medicine education is an enormous challenge, but indispensable for disaster preparedness. AIMS: We aimed to develop and implement a disaster medicine curriculum for medical student education that can serve as a peer-reviewed, structured educational guide and resource. Additionally, the process of designing, approving and implementing such a curriculum is presented. METHODS: The six-step approach to curriculum development for medical education was used as a formal process instrument. Recognized experts from professional and governmental bodies involved in disaster health care provided input using disaster-related physician training programs, scientific evidence if available, proposals for education by international disaster medicine organizations and their expertise as the basis for content development. RESULTS: The final course consisted of 14 modules composed of 2-h units. The concepts of disaster medicine, including response, medical assistance, law, command, coordination, communication, and mass casualty management, are introduced. Hospital preparedness plans and experiences from worldwide disaster assistance are reviewed. Life-saving emergency and limited individual treatment under disaster conditions are discussed. Specifics of initial management of explosive, war-related, radiological/nuclear, chemical, and biological incidents emphasizing infectious diseases and terrorist attacks are presented. An evacuation exercise is completed, and a mass casualty triage is simulated in collaboration with local disaster response agencies. Decontamination procedures are demonstrated at a nuclear power plant or the local fire department, and personal decontamination practices are exercised. Mannequin resuscitation is practiced while personal protective equipment is utilized. An interactive review of professional ethics, stress disorders, psychosocial interventions, and quality improvement efforts complete the training. CONCLUSIONS: The curriculum offers medical disaster education in a reasonable time frame, interdisciplinary format, and multi-experiential course. It can serve as a template for basic medical student disaster education. Because of its comprehensive but flexible structure, it should also be helpful for other health-care professional student disaster education programs.

Pharmacodynamics and organ storage of hydroxyethyl starch in acute hemodilution in pigs: influence of molecular weight and degree of substitution.

OBJECTIVE: To determine the differential influence of molecular weight and the degree of substitution of HES solutions on pharmacodynamics and pharmacokinetics including organ storage in a model of acute hemodilution in pigs. DESIGN: Prospective controlled randomized animal trial. INTERVENTIONS: After bleeding, 20 ml/kg, animals were substituted with 6% HES preparations (200/0.62, 200/0.5, and 100/0.5). MEASUREMENTS AND RESULTS: We did not observe any significant differences in the ability to sufficiently achieve plasma volume expansion and restoration of macrocirculation, nor maintenance of indicators of microcirculation between the groups. Urine production was significantly higher in HES-treated animals and highest in animals substituted with HES 100/0.5. Plasma clearance was measured under steady-state conditions with significantly reduced clearance for the HES 200/0.62 group compared with HES 100/0.5 and HES 200/0.5 (6.6 vs. 13.2 and 13.9 ml/min; P < or = 0.001), thus being dependent on the degree of substitution. Even after only 6 h, the amount of infused HES not detectable in either blood or urine was significantly higher in HES 200/0.62-treated animals (50.7% compared with HES 200/0.5 (28.8%), P = 0.020 and HES 100/0.5 (28.4%), P = 0.018), with its proportion rising over time. Finally, we could demonstrate considerable amounts of all HES solutions being stored in liver, kidney, lung, spleen and lymph nodes. CONCLUSIONS: All preparations analyzed sufficiently restored macro- and microcirculation; however, for all solutions relevant tissue storage of HES was observed after only 6 h.

Cognitive impairment after small-dose ketamine isomers in comparison to equianalgesic racemic ketamine in human volunteers.

BACKGROUND: Ketamine is increasingly used in pain therapy but may impair brain functions. Mood and cognitive capacities were compared after equianalgesic small-dose S(+)-, R(-)-, and racemic ketamine in healthy volunteers. METHODS: Twenty-four subjects received intravenous 0.5 mg/kg racemic, 0.25 mg/kg S(+)-, and 1.0 mg/kg R(-)-ketamine in a prospective, randomized, double-blind, crossover study. Hemodynamic variables, mood, and cognitive capacities were assessed for 60 min. RESULTS: Transient increases in blood pressure, heart rate, and catecholamines were similar after administration of all drugs. At 20 min after injection, subjects felt less decline in concentration and were more brave after S(+)- than racemic ketamine. They reported being less lethargic but more out-of-control after R(-)- than racemic ketamine. Ketamine isomers induced less drowsiness, less lethargy, and less impairment in clustered subjective cognitive capacity than racemic ketamine for the 60-min study. Objective concentration capacity [test time, S(+): 25.4 +/- 15.2 s, R(-): 34.8 +/- 18.4 s, racemic ketamine: 40.8 +/- 20.8 s, mean +/- SD] and retention in primary memory [test time, S(+): 4.6 +/- 1.2 s, R(-): 4.2 +/- 1.4 s, racemic ketamine: 4.0 +/- 1.4 s, mean +/- SD] declined less after S(+)- than either R(-)- or racemic ketamine at 1 min. At 5 min, immediate recall, anterograde amnesia, retention in primary memory, short-term storage capacity, and intelligence quotient were less reduced after the isomers than racemic ketamine. Speed reading and central information flow decreased less after S(+)- than racemic ketamine. CONCLUSIONS: Early after injection, ketamine isomers induce less tiredness and cognitive impairment than equianalgesic small-dose racemic ketamine. In addition, S(+)-ketamine causes less decline in concentration capacity and primary memory. The differences in drug effects cannot be explained by stereoselective action on one given receptor.
