The red zone in hospitals is a term used to refer to areas designated for patients with the highest priority who require isolation or intensive care. It is often used to separate patients with infectious diseases, particularly during the COVID-19 pandemic, to prevent the spread of infection within hospitals. The red zone may include isolation wards, intensive care units (ICUs), and operating rooms. Hospitals may implement color-coded zones, including red, to manage patient flow, bed allocation, and treatment priorities, especially during periods of high demand or crisis.

Red zones indicate contaminated areas
During the COVID-19 pandemic, hospitals implemented colour-coded zones to help manage patient flow and bed allocation, and to reduce the risk of infection. The red zone is used to indicate contaminated areas, usually referring to isolation wards, intensive care units (ICUs), and operating room suites. These areas are designed to contain the spread of infection and are subject to strict access control.
Red zones are typically established in areas of the hospital where patients with confirmed or suspected COVID-19 are treated. This includes patients with high-risk or unstable conditions, as well as those with minor symptoms or potential exposures. The red zone may also include isolation wards for patients with other infectious diseases, such as pneumonia.
The structural layout and workflow of red zones must adhere to hospital isolation technical regulations. This includes the use of negatively pressurised rooms, which help to prevent the spread of airborne contaminants. Red zones are typically staffed by a dedicated group of healthcare workers, including nurses, doctors, security guards, and cleaning staff. This staff subdivision helps to prevent cross-infection between different areas of the hospital.
Personal protective equipment (PPE) is crucial in red zones to protect healthcare workers from infection. In the COVID-19 red zones, PPE may include N95 masks, surgical masks, hair caps, goggles or face shields, gloves, gowns, and shoe coverings. These measures help to protect the health and safety of healthcare workers and prevent the further spread of the disease.

They are usually intensive care units or isolation wards
During the COVID-19 pandemic, hospitals adopted colour-coded zones to help manage patient flow and bed allocation, and to reduce the risk of infection. The red zone typically refers to contaminated areas, such as isolation wards and intensive care units (ICUs). These wards are designed to treat patients with infectious diseases, such as COVID-19, and to contain the spread of infection.
Red zones are subject to specific technical regulations and requirements, such as limiting access and using negatively pressurised rooms. Negative pressure rooms help to prevent cross-contamination and the spread of disease. Patients in the red zone are those who are the highest priority and require immediate care.
In the context of the pandemic, hospitals established separate areas, including pre-triage units, red zones, yellow zones, and green zones, to manage patients with different levels of risk of infection. The red zone itself can be further divided into red zone 1 and red zone 2. Red zone 1 is typically an indoor area with negative-pressure isolation rooms for patients at high risk of infection or with unstable conditions. Red zone 2 is often an outdoor area with a fever screening station for patients with minor symptoms or potential exposures.
The implementation of colour-coded zones, including red zones, has been crucial in helping hospitals cope with the influx of COVID-19 cases and providing optimal treatment to patients while adhering to social distancing protocols.

Hospitals use colour-coded zones to manage patient flow
During the pandemic, hospitals implemented various zones to separate patients based on their risk of infection and to restrict contaminated areas. The red zone, in this context, is designated for patients at high risk or possibly infected with unstable conditions. It includes negative-pressure isolation rooms, fully equipped with oxygen supply and monitors. Additionally, the red zone has a separate group of healthcare workers, including nurses, doctors, security guards, and cleaning staff, to prevent cross-infection with other areas.
The yellow zone serves as a buffer zone for patients with lung infiltration or pneumonia who require close monitoring and treatment. It is a separate area inside the emergency department (ED) with clear signage and delineated transition points. Healthcare workers transitioning between zones perform hand disinfection to prevent the spread of infection.
The green zone is another area within the hospital that houses certain facilities. For example, at Nottingham University Hospitals NHS Trust, the green zone is where the Patient Advice and Liaison Service (PALS) is located. It also includes accessible toilet facilities and changing rooms.
The use of colour-coded zones helps hospitals manage patient flow by allowing them to separate patients based on their risk of infection, provide optimal treatment while adhering to social distancing protocols, and allocate resources effectively. However, it is important to evaluate the potential risks these zones may pose to healthcare staff and patients due to inadequate screening and personal protective equipment (PPE) provisions.

Red zones have separate healthcare workers to prevent cross-infection
The COVID-19 pandemic has resulted in an increasing number of cases worldwide, causing governments to implement various measures to help hospitals cope. One such measure is the use of colour-coded zones, including red zones, to manage patient flow and bed allocation, and to prevent the spread of infection within hospitals.
Red zones are typically designated as contaminated areas, including isolation wards, intensive care units (ICUs), and operating room suites. They are used to treat patients with confirmed or suspected infectious diseases, such as COVID-19, to contain the spread of the infection. To prevent cross-infection, red zones have separate healthcare workers, including nurses, doctors, paramedics, support staff, and regular cleaning staff. This staff rotation schedule helps to limit exposure and reduce the risk of transmitting infections between different areas of the hospital.
In addition to separate staff, red zones also have specific requirements for personal protective equipment (PPE). Healthcare workers in the red zone are required to wear enhanced PPE, such as N95 masks, surgical masks, hair caps, goggles or face shields, gloves, gowns, and shoe coverings. These measures further protect both the staff and patients from cross-infection.
The creation of separate zones, including the red zone, has been crucial in managing the influx of COVID-19 cases and providing optimal treatment while adhering to social distancing protocols. It allows for the efficient allocation of resources and ensures that those who need immediate care can be prioritised. The implementation of these zones has been evaluated by professionals like Dr Ali Sheikh, who has discussed the effectiveness and risks of hospital zone protocols during the pandemic.

Hospitals face unprecedented demand
To manage patient flow and bed allocation, hospitals have implemented colour-coded zones, such as red, yellow, and green zones, to indicate different levels of risk of infection and to restrict contaminated areas. The red zone specifically refers to areas of the hospital that are contaminated and usually includes isolation wards, intensive care units (ICUs), and operating room suites. It also pertains to patients who are the highest priority. The implementation of these zones helps hospitals cope with the increasing number of Covid-19 cases and prevents the spread of infection within the hospital.
In the UK, NHS hospitals have also been facing unprecedented demand, with record numbers of A&E patients and hospital admissions. In November 2018, the number of patients being admitted as an emergency was up 6.3% from the previous year, and the number of A&E attendances was 3% higher. This has resulted in hospitals missing waiting-time targets and facing intense strain due to funding squeezes and staff shortages. The situation has prompted warnings of a difficult winter for the NHS, with the system already "operating in the red zone".
The red zone term has also been used more generally to refer to the expanding number of units in hospitals treating Covid-19 patients. In the Fayette County Hospital, for example, a red zone was set up on the second floor to treat patients with Covid-19, with another red zone in the ICU, where every patient was infected with the virus. The implementation of these zones helps to contain the spread of the infection within the hospital and protect the health system from functional collapse.
