BACKGROUND: During a large-scale airborne infectious disease outbreak, the number of patients needing hospital-based health care services may exceed available negative-pressure isolation room capacity. METHODS: To test one method of increasing hospital surge capacity, a temporary negative-pressure isolation ward was established at a fully functioning hospital. Negative pressure was achieved in a 30-bed hospital ward by adjusting the ventilation system. Differential pressure was continuously measured at 22 locations, and ventilation airflow was characterized throughout the ward...

OBJECTIVE: Surge capacity is one of the most important components of hospital preparedness for responding to emergencies and disasters. The ability to provide health and medical care during a sudden increase in the number of patients or victims of disasters is a main concern of hospitals. We aimed to perform a systematic review of hospital surge capacity in emergencies and disasters with a preparedness approach. METHODS: A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines...

Strong leadership is critical in disaster situations when "patient surge" challenges a hospital's capacity to respond and normally acceptable patterns of care are disrupted. Activation of the emergency operations plan triggers an incident command system structure for leadership decision making. Yet, implementation of the emergency operations plan and incident command system protocols is ultimately subject to nursing and hospital leadership at the service- and unit level. The results of these service-/unit-based leadership decisions have the potential to directly impact staff and patient safety, quality of care, and ultimately, patient outcomes...

Purpose Health systems are periodically confronted by crises - think of Severe Acute Respiratory Syndrome, H1N1, and Ebola - during which they are called upon to manage exceptional situations without interrupting essential services to the population. The ability to accomplish this dual mandate is at the heart of resilience strategies, which in healthcare systems involve developing surge capacity to manage a sudden influx of patients. The paper aims to discuss these issues. Design/methodology/approach This paper relates insights from resilience research to the four "S" of surge capacity (staff, stuff, structures and systems) and proposes a framework based on complexity theory to better understand and assess resilience factors that enable the development of surge capacity in complex health systems...

Transportation networks play a crucial role in human and animal societies. For a transportation network to be efficient, it must have adequate capacity to meet traffic demand. Network design becomes increasingly difficult in situations where traffic demand can change unexpectedly. In humans, network design is often constrained by path dependency because it is difficult to move a road once it is built. A similar issue theoretically faces pheromone-trail-laying social insects; once a trail has been laid, positive feedback makes re-routing difficult because new trails cannot compete with continually reinforced pre-existing trails...

The adult heart is uniquely designed and equipped to provide a continuous supply of energy in the form of ATP to support persistent contractile function. This high-capacity energy transduction system is the result of a remarkable surge in mitochondrial biogenesis and maturation during the fetal-to-adult transition in cardiac development. Substantial evidence indicates that nuclear receptor signaling is integral to dynamic changes in the cardiac mitochondrial phenotype in response to developmental cues, in response to diverse postnatal physiologic conditions, and in disease states such as heart failure...

Importance: The capacity of pediatric hospitals to provide treatment to large numbers of patients during a large-scale disaster remains a concern. Hospitals are expected to function independently for as long as 96 hours. Reverse triage (early discharge), a strategy that creates surge bed capacity while conserving resources, has been modeled for adults but not pediatric patients. Objective: To estimate the potential of reverse triage for surge capacity in an academic pediatric hospital...

Synopsis Although osteoarthritis (OA) has traditionally been considered a disease of older age, hip and knee OA can and does affect younger adults, with a profound impact on psychosocial well-being and work capacity. Obesity and a history of traumatic knee injury (eg, anterior cruciate ligament rupture and/or meniscal tear) are key risk factors for the accelerated development of knee OA, while structural hip deformities (including those contributing to femoroacetabular impingement syndrome) are strong predictors of early-onset hip OA...

Influenza is a viral respiratory disease capable of causing epidemics that represent a threat for global security. Mexico was the first country to notify the WHO of an outbreak of what later became the first influenza pandemic of the 21st Century, caused by the virus A(H1N1)2009. Before this event Mexico had a national pandemic influenza preparedness plan, which included seasonal influenza vaccination, stockpiles of personal protection equipment and strategic drugs, and risk communication strategies. During the epidemic, the national public health laboratory network and case surveillance systems were strengthened together with surge capacities for intensive care and delivery of antiviral drugs...

Boid inclusion body disease (BIBD) is a viral disease of boid snakes believed to be caused by reptarenavirus belonging to the family Arenaviridae. Unlike most mammalian arenaviruses, the reservoir host for reptarenavirus is still unknown. In this study, the pathological responses were evaluated in a mouse model for a period of 28 days. Blood and tissue samples (lung, liver, spleen, heart, kidney and brain) were collected for evaluation of hematology, biochemistry, histopathology and oxidative enzyme levels at six time points (1, 3, 7, 14, 21 and 28 days), after viral infection (2...

There is substantial current interest in the potential of radiation therapy for synergizing with novel immunotherapies to transform irradiated tumor into an immunogenic hub with capacity to ignite a powerful and adaptive longterm anti-cancer response. Interest stems from new insights into fundamental mechanisms underlying interactions between cancer, radiation and the immune system. Radically new immunotherapy approaches have been proposed, which target the immune system, rather than the cancer itself. Promising preliminary results on subsets of patients have led to a surge in research and clinical trials investigating the potential for combining new immunomodulatory agents with radiation therapy...

In July 2013, the National Council on Radiation Protection and Measurements convened a workshop for representatives from government, professional organizations, academia, and the private sector to discuss a potential shortage of radiation protection professionals in the not-too-distant future. This shortage manifests itself in declining membership of professional societies, decreasing enrollment in university programs in the radiological sciences, and perhaps most importantly, the imminent retirement of the largest birth cohort in American history, the so-called "baby boomer" generation...

INTRODUCTION: Hospitals worldwide are preparing for mass casualty incidents (MCIs). The Major Incident Hospital in the Netherlands was constructed 25 years ago as a dedicated hospital for situations wherein a sudden increase in medical surge capacity is mandated to handle an MCI. Over the years, more initiatives of dedicated MCIs have arisen. Herein, we compared the MCI facilities from three countries considering the reasons for construction and the functionality. METHODS: Three dedicated mass casualty hospitals and one hospital with a largely fortified structure were compared...

Outbreaks of infectious diseases or multi-casualty incidents have the potential to generate a large number of patients. It is a challenge for the healthcare system when demand for care suddenly surges. Traditionally, valuation of heath care spatial accessibility was based on static supply and demand information. In this study, we proposed an optimal model with the three-step floating catchment area (3SFCA) to account for the supply to minimize variability in spatial accessibility. We used empirical dengue fever outbreak data in Tainan City, Taiwan in 2015 to demonstrate the dynamic change in spatial accessibility based on the epidemic trend...
