Preparation for the next major incident: are we ready? Comparing major trauma centres and other hospitals.

OBJECTIVES: A major incident is any emergency requiring special arrangements by the emergency services. All hospitals are required by law to keep a major incident plan (MIP) detailing the response to such events. In 2006 and 2019, we assessed the preparedness and knowledge of key individuals in hospitals across England and found a substantial gap in responding to the MIP. In this report, we compare responses from doctors at major trauma centres (MTCs) and other hospitals (non-MTCs). METHODS: We identified trusts in England that received over 30 000 patients through the ED in the fourth quarter of 2016/2017. We contacted the on-call anaesthetic, emergency, general surgery and trauma and orthopaedic registrar at each location and asked three questions assessing their confidence in using their hospital's MIP: (1) Have you read your hospital's MIP? (2) Do you know where you can access your hospital's MIP guidelines? (3) Do you know what role you would play if an MIP came into effect while you are on call?We compared data from MTCs and non-MTCs using multinomial mixed proportional odds models. RESULTS: There was a modest difference between responses from individuals at MTCs and non-MTCs for question 2 (OR=2.43, CI=1.03 to 5.73, p=0.04) but no evidence of a difference between question 1 (OR=1.41, CI=0.55 to 3.63, p=0.47) and question 3 (OR=1.78, CI=0.86 to 3.69, p=0.12). Emergency medicine and anaesthetic registrars showed significantly higher preparedness and knowledge across all domains. No evidence of a systematic difference in specialty response by MTC or otherwise was identified. CONCLUSIONS: Confidence in using MIPs among specialty registrars in England remains low. Doctors at MTCs tended to be better prepared and more knowledgeable, but this effect was only marginally significant. We make several recommendations to improve education on major incidents.

A Biomarker-Centric Approach to Drug Discovery and Development: Lessons Learned from the Coronavirus Disease 2019 Pandemic.

Faced with the health and economic consequences of the global spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the biomedical community came together to identify, diagnose, prevent, and treat the novel disease at breathtaking speeds. The field advanced from a publicly available viral genome to a commercialized globally scalable diagnostic biomarker test in less than 2 months, and first-in-human dosing with vaccines and repurposed antivirals followed shortly thereafter. This unprecedented efficiency was driven by three key factors: 1) international multistakeholder collaborations, 2) widespread data sharing, and 3) flexible regulatory standards tailored to meet the urgency of the situation. Learning from the remarkable success achieved during this public health crisis, we are proposing a biomarker-centric approach throughout the drug development pipeline. Although all therapeutic areas would benefit from end-to-end biomarker science, efforts should be prioritized to areas with the greatest unmet medical needs, including neurodegenerative diseases, chronic lower respiratory diseases, metabolic disorders, and malignant neoplasms. SIGNIFICANCE STATEMENT: Faced with the unprecedented threat of the severe acute respiratory syndrome coronavirus 2 pandemic, the biomedical community collaborated to develop a globally scalable diagnostic biomarker (viral DNA) that catalyzed therapeutic development at breathtaking speeds. Learning from this remarkable efficiency, we propose a multistakeholder biomarker-centric approach to drug development across therapeutic areas with unmet medical needs.

Reflections from London's Level-1 Major Trauma Centres during the COVID crisis.

Emergence of the Covid-19 pandemic resulted in dramatic changes in global healthcare provision. Resources were redirected across all healthcare sectors to support the treatment of viral pneumonia with resultant effects on other essential services. We describe the impact of this on the provision of major trauma care in a major capital city.

Challenges of Treating Adenovirus Infection: Application of a Deployable Rapid-Assembly Shelter Hospital.

This article outlines the evolution of a rescue team in responding to adenovirus prevention with a deployable field hospital. The local governments mobilized a shelter hospital and a rescue team consisting of 59 members to assist with rescue and response efforts after an epidemic outbreak of adenovirus. We describe and evaluate the challenges of preparing for deployment, field hospital maintenance, treatment mode, and primary treatment methods. The field hospital established at the rescue scene consisted of a medical command vehicle, a computed tomography shelter, an X-ray shelter, a special laboratory shelter, an oxygen and electricity supply vehicle, and epidemic prevention and protection equipment. The rescue team comprised paramedics, physicians, X-ray technicians, respiratory therapists, and logistical personnel. In 22 days, more than 3000 patients with suspected adenovirus infection underwent initial examinations. All patients were properly treated, and no deaths occurred. After emergency measures were implemented, the spread of adenovirus was eventually controlled. An emergency involving infectious diseases in less-developed regions demands the rapid development of a field facility with specialized medical personnel when local hospital facilities are either unavailable or unusable. An appropriate and detailed prearranged action plan is important for infectious diseases prevention. (Disaster Med Public Health Preparedness. 2018;12:109-114).

Medical Effects of a Transuranic "Dirty Bomb".

The modern military battlefields are characterized by the use of nonconventional weapons such as encountered in the conflicts of the Gulf War I and Gulf War II. Recent warfare in Iraq, Afghanistan, and the Balkans has introduced radioactive weapons to the modern war zone scenarios. This presents the military medicine with a new area of radioactive warfare with the potential large scale contamination of military and civilian targets with the variety of radioactive isotopes further enhanced by the clandestine use of radioactive materials in the terrorist radioactive warfare. Radioactive dispersal devices (RDDs), including the "dirty bomb," involve the use of organotropic radioisotopes such as iodine 131, cesium 137, strontium 90, and transuranic elements. Some of the current studies of RDDs involve large-scale medical effects, social and economic disruption of the society, logistics of casualty management, cleanup, and transportation preparedness, still insufficiently addressed by the environmental and mass casualty medicine. The consequences of a dirty bomb, particularly in the terrorist use in urban areas, are a subject of international studies of multiple agencies involved in the management of disaster medicine. The long-term somatic and genetic impact of some from among over 400 radioisotopes released in the nuclear fission include somatic and transgenerational genetic effects with the potential challenges of the genomic stability of the biosphere. The global contamination is additionally heightened by the presence of transuranic elements in the modern warzone, including depleted uranium recently found to contain plutonium 239, possibly the most dangerous substance known to man with one pound of plutonium capable of causing 8 billion cancers. The planning for the consequences of radioactive dirty bomb are being currently studied in reference to the alkaline earths, osteotropic, and stem cell hazards of internally deposited radioactive isotopes, in particular uranium and transuranic elements. The spread of radioactive materials in the area of the impact would expose both military and civilian personnel to the blast and dust with both inhalational, somatic, and gastrointestinal exposure, in the aftermath of the deployment of RDDs. The quantities of radioactive materials have proliferated from the original quantity of plutonium first isolated in 1941 from 0.5 mg to the current tens of thousands of kilograms in the strategic nuclear arsenal with the obvious potential consequences to the biosphere and mankind. In an event of RDD employment, the immediate goal of disaster and mass casualty medicine would be a synchronized effort to contain the scope of the event, followed by cleanup and treatment procedures. A pragmatic approach to this problem is not always possible because of unpredictability of the terrorist-use scenarios.

Agility in adversity: Vaccines on Demand.

Is the US ready for a biological attack using Ebola virus or Anthrax? Will vaccine developers be able to produce a Zika virus vaccine, before the epidemic spreads around the world? A recent report by The Blue Ribbon Study Panel on Biodefense argues that the US is not ready for these challenges, however, technologies and capabilities that could address these deficiencies are within reach. Vaccine technologies have advanced and readiness has improved in recent years, due to advances in sequencing technology and computational power making the 'vaccines on demand' concept a reality. Building a robust strategy to design effective biodefense vaccines from genome sequences harvested by real-time biosurveillance will benefit from technologies that are being brought to bear on the cancer cure 'moonshot'. When combined with flexible vaccine production platforms, vaccines on demand will relegate expensive and, in some cases, insufficiently effective vaccine stockpiles to the dust heap of history.

Bacterial complications during pandemic influenza infection.

Evaluation of: Morens DM, Taubenberger JK, Fauci AS: Predominant role of bacterial pneumonia as a cause of death in pandemic influenza: implications for pandemic influenza preparedness. J. Infect. Dis. 198(7), 962-970 (2008). Secondary bacterial pneumonia is a common occurrence following lung influenza virus infection and leads to a significantly worse prognosis. This recent re-analysis of postmortem specimens and a vast number of reports from past influenza pandemics shows an extremely high frequency of lung colonization by bacterial species that are commonly found in the nasopharynx. This polymicrobial condition occurred in the preantibiotic era 1918-1919 influenza pandemic, but there is also evidence of bacterial co-infections in those outbreaks that occurred after antibiotic introduction. As such, antibiotic treatment should be included in any pandemic preparedness strategy. However, the choice of which antibiotic to use is important since some may even heighten morbidity and mortality.
