Respiratory viruses show multimodal transmission of infection, i.e., via large respiratory droplets which settle in the nearby area due to gravitation after being expelled by infected individuals (droplet transmission), fine respiratory droplets that remain suspended in the air for hours and travel long distances (airborne transmission), and direct/ indirect contact with infected secretions (contact transmission). The pandemic has also highlighted the knowledge gap among medical professionals regarding engineering issues of infection control and stresses the need for multidisciplinary team involvement for its management. The need for better hospital designs in terms of ventilation and prevention of infection transmission is one of the most important lessons being learned during the coronavirus disease-2019 (COVID-19) pandemic. The tremendous potential of respiratory viruses to create havoc in our lives was never so well recognized as of today. It can be easily understood that thermal comfort is compromised in buildings that are not mechanically fitted with HVAC systems, therefore the given building ventilation strategies are more helpful when climatic conditions are moderate or other measures are combined to maintain thermal comfort. Other measures like the use of portable air cleaning technologies and temporary negative-pressure rooms can be used as supplementary strategies in situations of demand surge. The current article describes building ventilation strategies (natural ventilation and hybrid ventilation) for hospitals where HVAC systems are either lacking or do not meet the recommended standards. Moreover, there is a need for the involvement of interdisciplinary teams to find innovative infection control solutions and doctors are frequently lacking in their understanding of building ventilation-related problems as well as their possible solutions. The current coronavirus disease-2019 pandemic has highlighted the need to find cost-effective and less resource-intensive engineering solutions. Even when the state-of-the-art technology was used to build airborne infection isolation rooms (AIIRs), recommended standards were often not met in field studies. Modern hospitals in high-income countries have mechanical systems of building ventilation also called HVAC (heating, ventilation, and air-conditioning) but installation and maintenance of such systems is a challenging and resource-intensive task. Photographer Katina Miller is a CLC assistant nurse manager for VA BHHCS.Among the various strategies for the prevention of airborne transmission, engineering measures are placed high in the hierarchy of control. Teresa Forbes is a public affairs officer for the VA Black Hills Health Care System (VA BHHCS). Providing compassionate patient care during this pandemic requires us to focus on safety while never forgetting the experience of the patient and their loved ones. If not for her sensitivity and concern there would be no family visits and the patients would pass away alone,” added Brett Krout, safety manager and workgroup team member. Clark deserves all the credit for the hospice patients’ family visits. Along with good hygiene and masking, it allows families to spend more time with their loved ones, providing relief to the family Negative air flow is effective to reduce the transmission of dangerous infectious diseases. The team quickly added a reverse air flow machine and ready the room to receive families. VA Black Hills Hospice Family RoomĪ multi-disciplinary team addressed engineering, infection prevention, clinical considerations and social work. This would provide an additional safety measure allowing up to three family members to visit for one hour each day. She recommended converting one of the family rooms adjacent to the patient hospice room to a negative pressure room. She thought of a way to give back some of what some families lost. Social worker Renee Radermacher works closely with Veterans and their families on the CLC. Clark is the Rehabilitation and Extended Care associate chief of staff. Under normal circumstances, hospice care provides a comforting environment for families to share uninterrupted, quality time with their loved one. Hospice services aim to relieve suffering and provide bereavement support to families. Mary Clark knew these protective measures were difficult for grieving families to accept.
