A Blockchain-Based Life-Cycle Environmental Management Framework for Hospitals in the COVID-19 Context.

During the coronavirus disease 2019 (COVID-19) emergency, many hospitals were built or renovated around the world to meet the challenges posed by the rising number of infected cases. Environmental management in the hospital life cycle is vital in preventing nosocomial infection and includes many infection control procedures. In certain urgent situations, a hospital must be completed quickly, and work process approval and supervision must therefore be accelerated. Thus, many works cannot be checked in detail. This results in a lack of work liability control and increases the difficulty of ensuring the fulfillment of key infection prevention measures. This study investigates how blockchain technology can transform the work quality inspection workflow to assist in nosocomial infection control under a fast delivery requirement. A blockchain-based life-cycle environmental management framework is proposed to track the fulfillment of crucial infection control measures in the design, construction, and operation stages of hospitals. The proposed framework allows for work quality checking after the work is completed, when some work cannot be checked on time. Illustrative use cases are selected to demonstrate the capabilities of the developed solution. This study provides new insights into applying blockchain technology to address the challenge of environmental management brought by rapid delivery requirements.

Establishing an integrated prevention and control system to ensure zero nosocomial infections - an analysis of the logistics support in controlling nosocomial infections during the hospital's fight against the COVID-19 epidemic.

Aim: To analyze the role of the logistics support services in nosocomial infection control during emergency periods, with a focus on job responsibilities including the organization of vehicle parking, supply of hospital meals, washing of medical bedding and clothing, disposal and management of medical sewage and waste, elevator services, disinfection of air conditioning systems, disinfection and cleaning of ambulances, management of hospital buildings, storage of sterilization supplies, reception and delivery of oxygen cylinders and protection of staff health as examples. Methods: The adjustment and optimization of the emergency support system and working mode as part of hospitals' response to major public emergencies were summarized, and the vital supporting role of the logistics support services in nosocomial infection control was analyzed. Results: The logistics support services played a crucial role in ensuring the high-performance operations of the hospitals and control of nosocomial infections, resulting in the excellent outcome of "zero infection" among hospital staff. Conclusion: Establishing a safe, flexible and efficient system for the logistics support services is important in ensuring an effective response by hospitals to health emergencies.

[Strategy of dental clinics to cope with the epidemic period of infectious diseases based on the experience of corona virus disease outbreak].

The outbreak of corona virus disease (COVID-19) has raised concerns among dentists to develop strategies to prevent infection of dental equipment, materials, and patients during an epidemic period. Strategies following the National Laws and Standards of China and local standards of several provinces for controlling cross-infection and instituting protective measures for medical staff in dental clinics during an epidemic period are discussed. A proposal is put forth for dental clinics that will face similar situations in the future. Further research is warranted to address potential problems that will be encountered under such dire circumstances.

Containing SARS-CoV-2 in hospitals facing finite PPE, limited testing, and physical space variability: Navigating resource constrained enhanced traffic control bundling.

The COVID-19 outbreak has led to a focus by public health practitioners and scholars on ways to limit spread while facing unprecedented challenges and resource constraints. Recent COVID-19-specific enhanced Traffic Control Bundling (eTCB) recommendations provide a cogent framework for managing patient care pathways and reducing health care worker (HCW) and patient exposure to SARS-CoV-2. eTCB has been applied broadly and has proven to be effective in limiting fomite and droplet transmissions in hospitals and between hospitals and the surrounding community. At the same time, resource constrained conditions involving limited personal protective equipment (PPE), low testing availability, and variability in physical space can require modifications in the way hospitals implement eTCB. While eTCB has come to be viewed as a standard of practice, COVID-19 related resource constraints often require hospital implementation teams to customize eTCB solutions. We provide and describe a cross-functional, collaborative on-the-ground adaptive application of eTCB initially piloted at two hospitals and subsequently reproduced at 16 additional hospitals and health systems in the US to date. By effectively facilitating eTCB deployment, hospital leaders and practitioners can establish clearer 'zones of risk' and related protective practices that prevent transmission to HCWs and patients. We outline key insights and recommendations gained from recent implementation under the aforementioned constraints and a cross-functional team process that can be utilized by hospitals to most effectively adapt eTCB under resource constraints.

CHARACTERISTICS and considerations in the medical treatment of COVID-19 in children.

It is rare for children to be in serious condition or die from coronavirus disease 2019 (COVID-19) caused by the 2019 novel coronavirus (severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2]) except for those with underlying diseases such as chronic lung disease (including asthma), cardiovascular disease, and immunosuppressive disease. Recently, patients with hyperinflammatory shock have been identified among children who are confirmed to have or are suspected of having SARS-CoV-2 infection. The presenting signs and symptoms are characterized by prolonged fever, abdominal pain, and cardiac involvement without any signs of pneumonia on chest computed tomography. However, it is uncertain at this time whether SARS-CoV-2 infection affects this syndrome. Compared with adults, quite a few children are asymptomatic even when infected with SARS-CoV-2, which could make these children serious sources of infection at home or in medical institutions. Considering these characteristics, it is important to take appropriate precautions during medical examinations and perform infection control in emergency departments to save the lives of both the children and adult patients. Most healthy children are suffering from huge stress due to restrictions against going outside and school closures as social means to control infection. It is possible that children are socially isolated when they come to the emergency department, and they might require mental or social support even if they are only complaining about their physical condition. Health-care providers are required to examine the children's circumstances carefully and cooperate with workers in other professions appropriately.
