How do we fight COVID-19? Military medical actions in the war against the COVID-19 pandemic in France.

'We are at war', French President Emmanuel Macron said in an address to the nation on 16 March 2020. As part of this national effort, the French Military Medical Service (FMMS) is committed to the fight against COVID-19. This original report aimed to describe and detail actions that the FMMS has carried out in the nationwide fight against the COVID-19 pandemic in France, as well as overseas. Experts in the field reported major actions conducted by the FMMS during the COVID-19 pandemic in France. In just few weeks, the FMMS developed ad hoc medical capabilities to support national health authorities. It additionally developed adaptive, collective en route care via aeromedical and naval units and deployed a military intensive care field hospital. A COVID-19 crisis cell coordinated the French Armed Forces health management. The French Military Centre for Epidemiology and Public Health provided all information needed to guide the decision-making process. Medical centres of the French Armed Forces organised the primary care for military patients, with the widespread use of telemedicine. The Paris Fire Brigade and the Marseille Navy Fire Battalion emergency departments ensured prehospital management of patients with COVID-19. The eight French military training hospitals cooperated with civilian regional health agencies. The French military medical supply chain supported all military medical treatment facilities in France as well as overseas, coping with a growing shortage of medical equipment. The French Armed Forces Biomedical Research Institute performed diagnostics, engaged in multiple research projects, updated the review of the scientific literature on COVID-19 daily and provided expert recommendations on biosafety. Finally, even students of the French military medical academy volunteered to participate in the fight against the COVID-19 pandemic. In conclusion, in an unprecedented medical crisis, the FMMS engaged multiple innovative and adaptive actions, which are still ongoing, in the fight against COVID-19. The collaboration between military and civilian healthcare systems reinforced the shared objective to achieve the goal of 'saving the greatest number'.

[Patient associated fire in theatre: are we ready to prevent and/or manage it? Assessment of the anaesthetist's knowledge in Lorraine]. / Feu d'un patient au bloc opératoire: sommes-nous prêts à gérer ce type d'incident ? Résultats d'une enquête faite auprès des médecins anesthésistes-réanimateurs lorrains.

OBJECTIVE: To assess knowledge amongst anaesthetists as regards to fire involving surgical patients in Lorraine. STUDY DESIGN: A cross-sectional study was conducted using a postal questionnaire. METHOD: A 22-item postal questionnaire was therefore sent to all anaesthetists working in Lorraine between January and March, 2011. RESULTS: One hundred and twenty-eight questionnaires were returned (response rate: 36%). Sixty-two percent of the respondents had never participated in fire safety training. Fifty percent could not recollect the location of the fire extinguisher in their surgical unit. Sixty-three percent ignored the existence of a memo written by the Afssaps summarizing how to use safely alcohol-based skin preparations in the presence of an electrosurgical unit. Sixty-five percent gave at least one incorrect response in grading the various modes of oxygen supply regarding the risk of fire. Only 48% were able to identify the surgeries which posed the greatest fire risk. In such cases, 40% of respondents were not aware that a FiO(2) should be maintained below 30%, 43% that the use of nitrous oxide was forbidden and 32% that it was necessary to respect a drying time after the application of an alcohol-based solution. Concerning the management of a fire, most of the answers were correct. Finally, 97% of the respondents wished to be better informed on this particular topic. CONCLUSION: Our survey underlines a lack of knowledge amongst anaesthetists towards the risk of patient associated fire in theatre.

[Antibodies against high frequency antigen and total knee replacement]. / Anticorps antipublic et prothèse totale de genou.

We report the perioperative management of a woman expressing an antibody against high frequency red cell antigen (anti-Kel4 antibody anti-kpb) who was scheduled for a total knee replacement. A specific strategy was designed to afford this major orthopedic surgery, considering specially the occurrence of unusual bleeding higher than the average bleeding assessed in our hospital in this indication. The transfusion of incompatible red cells may be responsible for acute hemolytic reaction. An autologous transfusion program, including cryopreservation, erythropoietin and iron support, was provided. Three autologous red cells units were collected before surgery. Compatible homologous red cells units were also available at the French bank for rare blood groups. We report logistical and medical problems that have occurred during the perioperative period.

[Understanding mistake-proofing]. / Comprendre la notion de détrompage.

The mistake-proofing concept often refers to physical devices that prevent actors from making a wrong action. In anaesthesiology, one immediately thinks to specific design of outlets for medical gases. More generally, the principle of mistake-proofing is to avoid an error, by placing knowledge in the world rather than knowledge in the head. As it often happens in risk management, healthcare has received information transfers from the industry. Computer is changing the concept of mistake-proofing, initially based on physical design, such as aerospace and automotive industry. The mistake-proofing concept may be applied to prevention, detection, and mitigation of errors. The forcing functions are a specific part of mistake-proofing: they prevent a wrong action or they force a virtuous one. Grout proposes a little shortcut to identify mistake-proofing devices: "If it is not possible to picture it in action, it is probably not a mistake-proofing device".

Violations and migrations in health care: a framework for understanding and management.

Violations are deliberate deviations from standard procedure. The usual reaction is to attempt to eliminate them and reprimand those concerned. However, the situation is not that simple. Firstly, violations paradoxically may be markers of high levels of safety because they need constraints and defences to exist. They may even become more frequent than errors in ultrasafe systems. Secondly, violations have both positive and negative aspects. On the one hand they occur frequently, increase system performance and individual satisfaction, are mostly limited to practices with limited safety consequences, and therefore are often tolerated or even encouraged by the hierarchy. On the other hand, extreme violations can lead to real danger or actual harm. This paper proposes a three phase model derived from Rasmussen's theory of migration to boundaries to explain the mechanism by which the deviance occurs, stabilizes, regresses, or progresses to harm. The model suggests that violations are unavoidable because system dynamics and deviances are markers of adaptation to this dynamicity. Violations cannot be eliminated but they can be managed. Solutions are specific to each step of the model, with a mix of relaxing constraints, increasing peer control (staff), and constraining dangerous individuals.

[Early rupture of a cryopreserved arterial allograft]. / Rupture précoce d'allogreffe artérielle cryopréservée: une complication à ne pas méconnaître.

Cryopreserved arterial allografts are used in vascular surgery to treat infected arterial prosthesis. This treatment reduces mortality and morbidity compared to conventional surgery. We observed a case of early rupture of the allograft with the death of the patient due to a misdiagnosis. Recent findings show that cases of rupture have been described, and that current cryopreservation protocols may be the cause of degeneration. To avoid a sudden death for the patient, this complication must be known to diagnose quickly and treat surgically before a final haemorrhagic shock.
