Anterooms in hospitals are small rooms that serve as a crucial barrier to prevent cross-contamination and outbreaks. They are used during hospital renovations and maintenance to contain dust, debris, and other construction-related hazards, as well as to isolate contaminated air, dust, and potentially deadly airborne pathogens. They are also used to provide infection control during a public health crisis, such as the COVID-19 pandemic, and to isolate patients with contagious illnesses or compromised immune systems. Anterooms can be constructed quickly and easily using temporary wall panels, and they play an essential role in enhancing safety, hygiene, privacy, and comfort in healthcare settings.

What You'll Learn
Infection control
Anterooms are an essential tool for infection control in hospitals, particularly during renovation, maintenance, and public health crises. They are small, sealed rooms with air filtration systems that remove harmful particles and pathogens from the air, creating a negative air pressure environment. This prevents the spread of contaminated air and isolates infected areas from other treatment spaces, protecting patients and staff.
Anterooms are also vital during public health crises, such as the COVID-19 pandemic. They serve as isolation rooms, helping to prevent the spread of infectious diseases by creating a negative air barrier. This type of isolation is critical for infection control, ensuring that infected patients are separated from other areas of the hospital.
The use of anterooms can vary depending on the specific needs of the hospital. For example, portable and reusable anterooms can be quickly installed in emergency situations, transforming areas not typically used for isolation into suitable patient isolation spaces. This flexibility allows hospitals to adapt to urgent situations and effectively manage infectious diseases.
In summary, anterooms play a crucial role in infection control within hospitals. They help contain and prevent the spread of contaminants, protecting patients and staff. By providing a sealed, filtered environment, anterooms ensure effective isolation and contribute to the overall safety of healthcare facilities during construction, maintenance, and public health emergencies.

Patient and staff protection
Anterooms in hospitals are essential for protecting patients and staff. They are small rooms that act as a buffer zone between contaminated and sterile areas, helping to prevent the spread of hospital-acquired infections (HAIs) and protecting patients from harmful debris and airborne pathogens. They are particularly important in settings where patients with compromised immune systems or contagious illnesses are present.
During hospital renovations and maintenance, anterooms are used to contain dust and debris, preventing them from spreading to other areas of the hospital. They also help to control contaminated air and the airflow between infected patients and other treatment areas, creating a negative air barrier to separate infected spaces from treatment spaces. This was especially important during the COVID-19 pandemic, where anterooms were used to slow the spread of the virus and protect patients and staff.
Anterooms also serve as transition spaces for medical staff to prepare before entering sterile environments, such as operating rooms or isolation wards. They provide a space for staff to safely remove contaminated items and clothing before returning to non-contaminated areas. This helps to maintain hygiene and prevent the spread of infections.
The use of anterooms in hospitals offers several benefits. They help to reduce the risk of cross-contamination, enhance privacy and comfort, and improve safety and efficiency. Additionally, reusable anteroom solutions, such as modular containment walls, can be quickly and easily constructed, providing a cost-effective and environmentally friendly option for hospitals. These walls are visually appealing, easy to disinfect, and reduce renovation noise, creating a calm and professional environment.

Airflow control
Anterooms are a crucial tool in hospitals for infection control and preventing the spread of contaminated air. They are small rooms entered before a larger room, acting as a barrier to separate contaminated and non-contaminated areas. Anterooms are especially important during hospital renovations and maintenance, as they contain dust and debris, preventing patients from contracting Hospital-Acquired Infections (HAIs). They also isolate contaminated air, dust, and potentially deadly airborne pathogens arising from construction or renovation.
Anterooms are designed to be negatively pressurised in relation to a hallway or patient room. Negative pressure is integral to the creation of an anteroom, but it is not necessarily a negative-pressure space. The pressurisation technique employed depends on the goal. For instance, to protect staff and normal patient care spaces from infectious pathogens, a "cascading" pressurisation technique is used. Here, the anteroom is designed to be negative to the hallway and positive to the patient room. This results in airflow from the hallway to the anteroom and then into the patient room.
To maintain the required pressure differential, the exhaust airflow quantity must exceed the supply airflow. More than 12 air changes per hour may be necessary, depending on factors such as room size and heating and cooling loads. A minimum airflow difference of 150 to 200 cubic feet per minute (CFM) is typically adequate for a well-sealed room. Negative-pressure isolation rooms must maintain a minimum 0.01-inch WC negative-pressure differential with the adjacent corridor, whether or not an anteroom is used.
Anterooms can be constructed using modular reusable containment walls, allowing for easy and quick installation. These walls come in various widths to customise the anteroom size based on specific requirements. The panels and doors used are designed to be durable, sound attenuating, and visually appealing, maintaining the professional appearance of the facility.

Isolation rooms
On the other hand, positive air pressure is used for patients with weakened immune systems who are not contagious but cannot be exposed to the same air as the rest of the hospital. In this case, clean, filtered air is constantly pumped into the room to keep contagious diseases out. With positive air pressure, one may feel air blowing out of the room under a closed door.
The level of isolation and precautions taken in an isolation room depend on the patient's condition and the type of infection or disease they have. Standard Precautions include hand washing, gloves, face shields, and masks to prevent the spread of bodily fluids. Airborne Precautions are recommended for patients with infections transmitted by airborne droplets, and require a private room capable of 6-12 air changes per hour. Droplet Precautions are necessary for patients with infections transmitted by droplets, and Contact Precautions are used for patients with infections transmitted through direct or indirect contact.

Construction and renovation
Anterooms are an essential component of hospital construction and renovation, providing a range of benefits that contribute to safety, hygiene, privacy, and comfort. They are particularly useful in healthcare settings for infection control, creating a crucial barrier to prevent cross-contamination.
During construction and renovation projects, anterooms are constructed using temporary wall panels to create a sealed, negative-pressure space. These panels are available in various widths and can be customised to fit the specific job requirements. They are designed to be easily installed, cost-effective, and reusable, making them a sustainable and budget-friendly option.
In the context of hospitals, anterooms serve as a buffer zone between contaminated construction areas and sterile patient environments. They help control dust, debris, and other construction-related hazards, protecting patients and staff from potential risks. Anterooms also provide privacy for workers and a space to safely remove contaminated items and equipment before entering non-contaminated areas.
The use of anterooms during hospital renovations is especially advantageous as it allows facilities to continue operating without shutting down entire wings or disrupting patient care. They are an effective tool for controlling airflow and contaminated air, reducing the spread of Hospital-Acquired Infections (HAIs) and protecting patients with compromised immune systems.
Additionally, anterooms can be utilised as isolation rooms during public health crises, such as the COVID-19 pandemic. They help prevent the spread of infectious diseases by isolating infected areas from treatment spaces, providing an extra layer of protection for patients and healthcare workers.
