Projecting COVID-19 isolation bed requirements for people experiencing homelessness.

As COVID-19 spreads across the United States, people experiencing homelessness (PEH) are among the most vulnerable to the virus. To mitigate transmission, municipal governments are procuring isolation facilities for PEH to utilize following possible exposure to the virus. Here we describe the framework for anticipating isolation bed demand in PEH communities that we developed to support public health planning in Austin, Texas during March 2020. Using a mathematical model of COVID-19 transmission, we projected that, under no social distancing orders, a maximum of 299 (95% Confidence Interval: 223, 321) PEH may require isolation rooms in the same week. Based on these analyses, Austin Public Health finalized a lease agreement for 205 isolation rooms on March 27th 2020. As of October 7th 2020, a maximum of 130 rooms have been used on a single day, and a total of 602 PEH have used the facility. As a general rule of thumb, we expect the peak proportion of the PEH population that will require isolation to be roughly triple the projected peak daily incidence in the city. This framework can guide the provisioning of COVID-19 isolation and post-acute care facilities for high risk communities throughout the United States.

Planning and Design of a Full-Outer-Air-Intake Natural Air-Conditioning System for Medical Negative Pressure Isolation Wards.

In the beginning of 2020, the coronavirus (COVID-19) pandemic started to spread globally, causing panic to the lives of people around the world; many countries executed lockdown of cities or even total lockdown of the entire countries. The coronavirus disease (COVID-19) is transmitted via air droplets. In medical environments that use traditional hermetic ventilation systems, medical personnel who come in contact with patients are more susceptible to infection compared to regular staff; therefore, the air flow and air quality of hermetic negative pressure isolation wards are highly critical. For this purpose, the study proposes a full-outer-air-intake natural air-conditioning system for negative pressure isolation wards. This innovative system draws in large amounts of fresh external air to greatly improve the air exchange rate in wards; negative pressure environments can be implemented depending on requirements to solve the issue of nosocomial infections in traditional negative pressure isolation wards that draw air from within the hospital. This greatly reduces the probability of nosocomial infection and infection via air droplets; furthermore, the system's intake and exhaust paths are completely isolated, solving the issue of air cross-contamination. Based on the results from the experiment site, this innovative system was designed and implemented based on the guidelines of hospital facilities and achieved air exchange per hour in excess of 12 times/hour, reaching a maximum of 54.5 times/hour. Indoor CO2 concentration was 576 ppm, negative pressure was -14 Pa, indoor temperature was 23.3°C, indoor humidity was 54.1%, and sensible heat exchange efficiency (ηs) was 105.88% which effectively reduced ventilation load. Therefore, this innovative full-outer-air-intake natural air-conditioning system can provide medical staff and patients with a safe and healthy environment that prevents cross-infection.

Effectiveness of negative pressure isolation stretcher and rooms for SARS-CoV-2 nosocomial infection control and maintenance of South Korean emergency department capacity.

OBJECTIVE: There are growing concerns regarding the lack of COVID-19 pandemic response capacity in already overwhelmed emergency departments (EDs), and lack of proper isolation facilities. This study evaluated the effectiveness of the negative pressure isolation stretcher (NPIS) and additional negative pressure isolation rooms (NPIRs) on the maintenance of emergency care capacity during the COVID-19 outbreak. METHODS: A before and after intervention study was performed between February 27, 2020 and March 31, 2020 at the ED of Chungbuk National University Hospital, Cheongju, South Korea. A total of 2455 patients who visited the ED during the study period were included. Interventions included the introduction of the NPIS and additional NPIRs in the ED. The main outcome of the study was frequency of medical cessation. Secondary outcomes were the average number of ED visits and lengths of stay. RESULTS: After the intervention, average frequency of medical cessation was significantly decreased from 1.6 times per day (range 0-4) in the pre-intervention period to 0.6 times per day (range 0-3) in the post-intervention period (p-value <0.01). On the other hand, the number of patients visiting the ED increased significantly from 67.2 persons per day (range 58-79) pre-intervention to 76.3 persons per day (range 61-88) post-intervention (p value <0.01). However, there were no statistically significant differences in the average ED length of stay across the study phases (p value = 0.50). CONCLUSIONS: This intervention may provide an effective way to prepare and meet the ED response needs of the COVID-19 pandemic.

Aerosol boxes and barrier enclosures for airway management in COVID-19 patients: a scoping review and narrative synthesis.

Exposure of healthcare providers to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a significant safety concern during the coronavirus disease 2019 (COVID-19) pandemic, requiring contact/droplet/airborne precautions. Because of global shortages, limited availability of personal protective equipment (PPE) has motivated the development of barrier-enclosure systems, such as aerosol boxes, plastic drapes, and similar protective systems. We examined the available evidence and scientific publications about barrier-enclosure systems for airway management in suspected/confirmed COVID-19 patients. MEDLINE/Embase/Google Scholar databases (from December 1, 2019 to May 27, 2020) were searched for all articles on barrier enclosures for airway management in COVID-19, including references and websites. All sources were reviewed by a panel of experts using a Delphi method with a modified nominal group technique. Fifty-two articles were reviewed for their results and level of evidence regarding barrier device feasibility, advantages, protection against droplets and aerosols, effectiveness, safety, ergonomics, and cleaning/disposal. The majority of analysed papers were expert opinions, small case series, technical descriptions, small-sample simulation studies, and pre-print proofs. The use of barrier-enclosure devices adds to the complexity of airway procedures with potential adverse consequences, especially during airway emergencies. Concerns include limitations on the ability to perform airway interventions and the aid that can be delivered by an assistant, patient injuries, compromise of PPE integrity, lack of evidence for added protection of healthcare providers (including secondary aerosolisation upon barrier removal), and lack of cleaning standards. Enclosure barriers for airway management are no substitute for adequate PPE, and their use should be avoided until adequate validation studies can be reported.

Disposable Isolation Device to Reduce COVID-19 Contamination During CT Scanning.

RATIONALE AND OBJECTIVES: The use of chest computed tomography (CT) in the era of the COVID-19 pandemic raises concern regarding the transmission risks to patients and staff caused by CT room contamination. Meanwhile the Center for Disease Control guidance for air exchange in between patients may heavily impact workflows. To design a portable custom isolation device to reduce imaging equipment contamination during a pandemic. MATERIALS AND METHODS: Center for Disease Control air exchange guidelines and requirements were reviewed. Device functional requirements were outlined and designed. Engineering requirements were reviewed. Methods of practice and risk mitigation plans were outlined including donning and doffing procedures and failure modes. Cost impact was assessed in terms of CT patient throughput. RESULTS: CT air exchange solutions and alternatives were reviewed. Multiple isolation bag device designs were considered. Several designs were custom fabricated, prototyped and reduced to practice. A final design was tested on volunteers for comfort, test-fit, air seal, and breathability. Less than 14 times enhanced patient throughput was estimated, in an ideal setting, which could more than counterbalance the cost of the device itself. CONCLUSION: A novel isolation bag device is feasible for use in CT and might facilitate containment and reduce contamination in radiology departments during the COVID Pandemic.

Evacuación aeromédica de pacientes COVID-19. Reporte de casos / Case reports: Aeromedical evacuation of patients COVID-19

BACKGROUND: The aeromedical evacuation in the Chilean Air Force has had an important development in the last 15 years. The coronavirus disease declared as a global pandemic by the WHO has generated the challenge of transferring highly infectious patients to centers of greater complexity. The objective of this article is to report our experience in the transfer of COVID ­ 19 patients in constant attention and medical monitoring. CLINICAL CASE REPORTS: The aeromedical evacuation of 2 COVID-19 patients was performed from the Hanga Roa Hospital, Rapa Nui, to the National Thorax Institute, Metropolitan Region, in a Lockheed Hercules C-130, which corresponds to a pressurized fixed-wing airplane. The transfer was carried out with the corresponding personal protection elements and in individual isolation capsules with advanced negative pressure life support (ISO ­ POD), in order to reduce the level of contagion to the aero sanitary crew and minimize the impact on the flight material used. DISCUSSION: The transfer was carried out achieving all the objectives set out under a strict security protocol and the two COVID-19 patients were transferred successfully. The negative pressure isolation capsule system was safe and reliable, since no crew member presented symptoms or was infected by COVID -19, and also allowed the transfer of highly contagious patients during an 8-hour flight operation.

INTRODUCCIÓN: La evacuación aeromédica en la Fuerza Aérea de Chile ha tenido un importante desarrollo en los últimos 15 años. La enfermedad por coronavirus declarada como pandemia mundial por la OMS ha generado el desafío de trasladar pacientes altamente infecciosos a centros de mayor complejidad. El objetivo de este artículo es reportar nuestra experiencia en el traslado de pacientes COVID ­ 19 en constante atención y monitorización médica. REPORTE DE CASOS CLÍNICOS: Se realizó la evacuación aeromédica de 2 pacientes COVID ­ 19 desde el Hospital de Hanga Roa, Rapa Nui, hacía el Instituto Nacional del Tórax, Región Metropolitana, en un Lockheed Hércules C-130, que corresponde a un avión de ala fija presurizado. El traslado se realizó con los elementos de protección personal correspondientes y en capsulas de aislamiento individual con soporte vital avanzado a presión negativa (ISO ­ POD), con la finalidad de reducir el nivel de contagio a la tripulación aero sanitaria y minimizar el impacto en el material de vuelo utilizado. DISCUSIÓN: El traslado se desarrolló logrando todos los objetivos planteados bajo un estricto protocolo de seguridad y los dos enfermos COVID-19 fueron trasladados de manera exitosa. El sistema de cápsulas de aislamiento a presión negativa fue seguro y confiable, ya que ningún miembro de la tripulación presento sintomatología o resultó contagiado por COVID -19, y además permitió trasladar pacientes altamente contagiosos durante una operación de vuelo de 8 horas.

The effectiveness of antibacterial curtains in comparison with standard privacy curtains against transmission of microorganisms in a hospital setting.

Studies have shown a correlation between a cleaner patient environment and lower infection rates and reduced risk of transmission. Privacy curtains are potentially important sites of bacterial contamination in hospitals. Privacy curtains integrated with antimicrobial properties have been shown to increase the time to first contamination compared with standard privacy curtains. In this study, we examined the difference in bacterial colonization of different curtains. We experimentally contaminated antibacterial Fantex protective curtains and compared the bacterial counts to natural contamination of privacy curtains. There was a significant reduction in the CFU/cm2 on antibacterial Fantex protective privacy curtains after 24 hours of experimental contamination with Pseudomonas aeruginosa, Acinetobacter baumannii, methicillin-resistant Staphylococcus aureus (MRSA) or extended-spectrum-producing organisms (Escherichia coli or Klebsiella pneumoniae), compared to standard privacy curtains. Levels of environmental contamination with S. epidermis, Streptococcus viridians, E. coli, S. haemolyticus, S. aureus, S. capitis, non-fermenting Gram-negative bacteria, and Bacillus species were also significantly less on the Fantex curtains after two months hanging in the emergency department. Healthcare facilities may find that addressing surfaces, including use of antibacterial privacy curtains, is an effective horizontal strategy for addressing healthcare-associated infections across the board.

Music in Seclusion Rooms-Development, Implementation, and Initial Testing of a Music Listening Device.

Although presented as a care measure, the use of seclusion rooms (SR) is controversial for both ethical and therapeutic reasons. Given that music seems to have a positive impact on psychiatric patients, offering them the possibility of listening to music might help to improve the care dimension of SR use. This study aimed to develop, implement, and test a musical listening device that would be completely at patients' disposal, easy to use and beneficial to the quality of care provided in SRs. Over a 12-week period, interviews were conducted with nurses (N = 6) caring for patients placed in an equipped SR. The music player was user friendly, encouraged patients to make choices and decisions, helping them to regain control over themselves and their behavior, and elicited various patient-nurse interactions, thus contributing to the establishment of a caring relation. Further research is warranted to examine whether the systematic use of the music player has an impact on the subjective experience of both patients and caregivers, and on daily ward routine.

Aeromedical Transfer of Patients with Viral Hemorrhagic Fever.

For >40 years, the British Royal Air Force has maintained an aeromedical evacuation facility, the Deployable Air Isolator Team (DAIT), to transport patients with possible or confirmed highly infectious diseases to the United Kingdom. Since 2012, the DAIT, a joint Department of Health and Ministry of Defence asset, has successfully transferred 1 case-patient with Crimean-Congo hemorrhagic fever, 5 case-patients with Ebola virus disease, and 5 case-patients with high-risk Ebola virus exposure. Currently, no UK-published guidelines exist on how to transfer such patients. Here we describe the DAIT procedures from collection at point of illness or exposure to delivery into a dedicated specialist center. We provide illustrations of the challenges faced and, where appropriate, the enhancements made to the process over time.

Transportation capacity for patients with highly infectious diseases in Europe: a survey in 16 nations.

Highly infectious diseases (HIDs) are defined as being transmissible from person to person, causing life-threatening illnesses and presenting a serious public health hazard. In most European Union member states specialized isolation facilities are responsible for the management of such cases. Ground ambulances are often affiliated with those facilities because rapid relocation of patients is most desirable. To date, no pooled data on the accessibility, technical specifications and operational procedures for such transport capacities are available. During 2009, the 'European Network for HIDs' conducted a cross-sectional analysis of hospitals responsible for HID patients in Europe including an assessment of (a) legal aspects; (b) technical and infrastructure aspects; and (c) operational procedures for ground ambulances used for HID transport. Overall, 48 isolation facilities in 16 European countries were evaluated and feedback rates ranged from 78% to 100% (n = 37 to n = 48 centres). Only 46.8% (22/47) of all centres have both national and local guidelines regulating HID patient transport. If recommended, specific equipment is found in 90% of centres (9/10), but standard ambulances in only 6/13 centres (46%). Exclusive entrances (32/45; 71%) and pathways (30/44; 68.2%) for patient admission, as well as protocols for disinfection of ambulances (34/47; 72.3%) and equipment (30/43; 69.8%) exist in most centres. In conclusion, the availability and technical specifications of ambulances broadly differ, reflecting different preparedness levels within the European Union. Hence, regulations for technical specifications and operational procedures should be harmonized to promote patient and healthcare worker safety.

Isolation unit for multidrug-resistant tuberculosis patients in a low endemic country, a step towards the World Health Organization End TB Strategy.

Tuberculosis (TB) remains a threat to public health and is the second cause of death due to a single infectious agent after HIV/AIDS. The worldwide distribution of TB is heterogeneous. The incidence is decreasing in most high-income regions, but the situation remains worrying in many parts of the world. The emergence of Mycobacterium tuberculosis strains resistant to key agents used in treatment (rifampin and isoniazid) contributes to TB transmission around the world. To achieve TB elimination, both high and low endemic countries must upscale their efforts to decrease disease transmission and improve cure rates. Management of drug-resistant TB is of particular importance. In this paper, we discuss the different models of care of multidrug-resistant TB (MDR-TB), the ethical considerations and the specific constraints present in high income countries. The management model chosen by the Belgian TB specialists in accordance with public health authorities as well as building of a specific MDR/XDR-TB isolation unit are also discussed.

Actuación de enfermería ante un paciente con sospecha de enfermedad del virus del Ébola / The performance of nursing a patient with suspected case of Ebola

El virus del Ébola se detectó por primera vez en 1976 en la República democrática del Congo y en el sur de Sudán. Desde entonces, ha habido varios brotes en África occidental, pero es en 2014 cuando amenazó con convertirse en un problema de salud pública a nivel mundial. Una de las principales causas de este fenómeno es la expansión del virus desde zonas rurales a zonas urbanizadas desorganizadas. La epidemia avanzó de forma imparable a pesar de los esfuerzos de la OMS, Médicos Sin Fronteras y los gobiernos de Sierra Leona, Guinea y Liberia, y alcanzó una cifra de aproximadamente 5000 fallecidos, de los cuales un 5 % eran personal sanitario (noviembre 2014). España fue el primer país con un caso de contagio fuera de África. La infección de una trabajadora sanitaria de un hospital de Madrid hizo cundir el pánico en todo el Estado. Ello obligó a las autoridades sanitarias nacionales e internacionales a revisar y actualizar los protocolos de actuación ante casos de pacientes con sospecha de enfermedad del virus del Ébola. Se presenta un caso clínico en el que se describen los cuidados a un paciente con sospecha de enfermedad por virus del Ébola y las medidas de aislamiento de nivel IV (AU)

Ebola virus was first detected in Congo and south of Sudan in 1976. Since then, there have been several limited spreads in occidental Africa, but it is in 2014 when it became a worldwide public health problem. One of the main causes of this phenomenon was the migration of the virus from rural areas to marginal urban areas. The epidemic advanced despite the efforts of WHO, Medicines Sans Frontiers and the governments of Guinea, Liberia and Sierra Leone to stop it. The number of deaths was around 5000, and 5 % of these were sanitary workers. Spain was the first country with a contagion outside Africa. One sanitary person from a Hospital in Madrid got the virus and resulted in panic all around Spain. This forced the sanitary authorities to revise and actualize protocols when we treat patients under suspicion of Ebola virus infection. We report a case in which we describe the care we provide to a patient with suspected Ebola disease and isolation measures level IV (AU)

A Novel Approach to CT, MR, and PET Examination of Patients with Infections Requiring Stringent Airborne Precautions.

PURPOSE: To investigate the feasibility of using a modified portable isolation chamber, which conforms to Centers for Disease Control and Prevention (CDC) isolation requirements, in the imaging of infectious patients. MATERIALS AND METHODS: This study was approved by the ethics committee, and all participants gave written informed consent. In this prospective study, the isolation chamber was assessed for computed tomographic (CT), magnetic resonance (MR), and positron emission tomographic (PET) image uniformity and noise by using uniform phantoms. For each modality, equivalent phantom examinations were performed without the isolation chamber. Paired analyses of the differences from these baseline values were conducted by finding the mean difference in the matched sections for each image quality parameter. A potential increase in CT patient dose was assessed, and MR radiofrequency (RF) interference was monitored. Eight participants with active pulmonary tuberculosis (mean age, 48.1 years; age range, 26-88 years; five men, three women) were then examined within a hybrid PET/MR imager. The 95% confidence intervals for the difference in the two matched population means were determined by using the two-sided t distribution for each of the phantom study imaging modalities. RESULTS: Phantom images were evaluated for image uniformity and noise. Increased image noise can affect low contrast resolution, which has the potential to mimic or mask abnormalities when the differences between healthy and diseased tissues are small; clinically, CT image noise is maintained at a constant level with dose modulation. Increased attenuation of annihilation photons, when not corrected for, could lead to photopenic areas on the PET image; PET image nonuniformity complied with guidelines. Artifacts on the MR image due to RF noise spikes could mask abnormalities; paired analysis of variations in MR imaging mean signal-to-noise ratio and uniformity from baseline were within 5% for both gradient-echo and spin-echo sequences. In the eight participants who underwent imaging, the increased radiation dose for the attenuation of the isolation chamber would have resulted in a mean increase in patient size-specific dose estimate of 0.32 mGy ± 0.04 (standard deviation). The RF noise assessment revealed no prominent increase at any frequency band. The eight participants were examined within the isolation chamber without incident. CONCLUSION A modified portable isolation chamber, which conforms to CDC infection control guidelines, was found to be feasible within the confines of CT, MR imaging, and PET environments.

Airplane transport isolators may loose leak tightness after rapid cabin decompression.

Air medical transport of patients suffering of highly infectious diseases is typically performed employing portable isolation chambers. Although the likelihood of decompression flight emergencies is low, sustainability of the devices used is crucial. When a standard isolation unit was subjected to an explosive cabin decompression of 493 hPa, simulating a 32808 ft flight level accident, leak tightness of the unit was lost due to rupture of the bag caused by over expansion. When the pressure chamber experiment was repeated with a modified unit, distension was minimized by an additional compensation air bag, thus ensuring leak tightness.
