Hospital Toilets: Why No Lids?

why do hospital toilets not have lids

The absence of lids on hospital toilets is a common observation, and there are several reasons behind this design choice. One of the primary concerns is accessibility for patients with mobility issues. Installing lids might create challenges for individuals with physical limitations. Additionally, there is a belief that lids would provide another surface for cleaning, potentially increasing the workload for janitorial staff. However, the lack of lids can have negative consequences. The flushing of lidless toilets can result in the aerosolization of harmful pathogens, such as Clostridium difficile, posing risks for the spread of infections within hospitals. This has led to discussions about potential solutions, including self-closing lids or automatic seals when flushing. Nonetheless, critics argue that diligent cleaning, proper hand hygiene, and infection prevention measures may be more effective in mitigating the risks associated with lidless toilets.

Lids prevent the aerosolization of pathogens

The absence of lids on hospital toilets is a patient safety issue. Lids prevent the aerosolization of pathogens into the environment. The powerful current of water generated in each flush causes intense splashing along with the formation and bursting of bubbles that ultimately release two forms of droplets. Splashing releases large droplets of water containing particles of waste and contagious germs onto the toilet seat. The bursting of bubbles releases many smaller water droplets into the air that quickly evaporate, leaving behind "droplet nuclei"—dense compositions of airborne waste and pathogens. These aerosolized droplet nuclei produced from toilet flushes are commonly referred to as "toilet plumes".

Recent research shows that droplet nuclei are consistently able to host pathogens such as bacteria and can continue to spread disease for long periods while airborne. In one study, a toilet that contained Clostridium difficile (commonly known as C. diff, a bacteria that causes diarrhoea and colon inflammation) released the bacteria 25 cm into the air when flushed. It took 90 minutes for the bio-aerosol concentration to decrease 11-fold, placing many individuals at risk of contracting the disease within that time frame. The authors of a UK study speculated that asymptomatic carriers of C. difficile who use lidless toilets may be the cause of hospital outbreaks of the infection.

However, some argue that installing lids may not be the answer. A lid that must be lifted for use and closed for flushing may cause problems for patients with mobility problems. That may necessitate more complex technological solutions to make it easier for such patients. Furthermore, lids would be another surface to clean. Diligent cleaning of restrooms, proper hand hygiene, and continued practice of other infection prevention and control measures are more effective measures.

In the absence of lids, hospitals can follow the Oncology Nursing Society's (ONS) guidance. ONS recommends that nurses apply a plastic-backed absorbent pad (chemo mat) over the toilet bowl before flushing to avoid toilet plume. Hospital staff flushing human waste in toilets without lids should wear personal protective equipment such as gloves, chemotherapy gowns, respiratory masks, and face shields.

Lids may be hard to lift for some patients

Toilet lids play an important role in limiting the spread of diseases in bathrooms. The powerful current of water generated in each flush causes intense splashing and the formation and bursting of bubbles, which release two forms of droplets. Splashing releases large droplets of water containing particles of waste and contagious germs onto the toilet seat, while the bursting of bubbles releases smaller water droplets into the air that quickly evaporate, leaving behind "droplet nuclei"—dense compositions of airborne waste and pathogens. These aerosolized droplet nuclei produced from toilet flushes are commonly referred to as "toilet plumes".

Hospitals often do not have lidded toilets because it is believed that lids might be hard to lift for some patients, especially those with mobility problems. A lid that must be lifted for use and closed for flushing may cause difficulties for patients with limited mobility. This issue may necessitate more complex technological solutions, such as self-closing lids or foot-operated mechanisms, to make it easier for patients to use the toilet safely and comfortably.

While the absence of lids can pose challenges for certain patients, it is important to prioritize infection prevention and control. The aerosolization of pathogens, such as Clostridium difficile (C. difficile), can occur when lidless toilets are flushed, potentially spreading infections within the hospital environment. Proper hand hygiene, diligent cleaning of restrooms, and other infection control measures are crucial to mitigate these risks effectively.

To address the concerns related to lidless toilets in hospitals, a combination of approaches can be considered. Firstly, hospitals can invest in technological advancements, such as self-closing lids or foot-operated mechanisms, to make it easier for patients with mobility issues to use the lids safely. Secondly, public service announcements and educational initiatives can remind patients and the general public about the importance of lowering the lid before flushing. This can be reinforced through media campaigns and by including it in school curricula. Finally, hospitals should continue to prioritize diligent cleaning, proper hand hygiene, and strict adherence to infection prevention and control measures to minimize the spread of diseases, even in the absence of lids.

Lids are another surface to clean

One of the reasons hospital toilets often do not have lids is that they are considered an additional surface to clean. This is especially important in hospitals, where sanitation is critical to prevent the spread of infections and diseases.

Maintaining hygiene in hospitals is a challenging task, and every surface must be meticulously cleaned and disinfected to ensure the safety of patients and staff. Toilets with lids would require extra effort and time to clean, as the lids would need to be lifted, wiped down, and sanitized separately.

In a busy hospital setting, cleaning staff are often under pressure to work efficiently and maintain high standards of cleanliness. Having one less surface to clean can streamline their workflow and ensure that other critical areas receive adequate attention. It also reduces the risk of cross-contamination, as there is one less surface that can harbour pathogens.

Furthermore, lids can be difficult to clean properly, especially if they are not properly closed or if they have intricate designs or hinges. The hinges and crevices of toilet lids can accumulate dirt, dust, and bacteria, making them potential breeding grounds for germs if not cleaned thoroughly.

While lids can play a role in infection control by preventing the aerosolization of pathogens, their effectiveness depends on users remembering to close them before flushing. As Dr Doug Sider points out, even in hospitals with lidded toilets, the failure of one patient to close the lid or wash their hands after touching it could undermine the benefits. Therefore, the absence of lids in hospital toilets is sometimes justified as a way to simplify cleaning procedures and ensure overall hygiene standards are met.

Lids may not guarantee fewer infections

While toilet lids are believed to prevent the aerosolization of pathogens, there are several reasons why hospitals may choose not to install them. Firstly, lids might be hard to lift for individuals with mobility issues. Secondly, lids would provide another surface that needs to be cleaned, potentially spreading rather than reducing infections.

Indeed, some experts argue that lids may not guarantee fewer infections. Dr. Doug Sider, medical director of communicable diseases and acting medical director of infection prevention and control for Public Health Ontario, states that retrofitting toilets with lids may not be the best use of scarce hospital resources. He questions the effectiveness of lids, pointing out that even with lidded toilets, there is no assurance that users will put the lid down after each use.

Furthermore, the success of lids in preventing infections relies on proper hand hygiene and other infection control measures. As Dr. Sider notes, the failure of one patient to wash their hands after touching a lidded toilet could undermine its value in preventing the spread of infections. This highlights the multifaceted nature of infection control in hospitals, where multiple factors contribute to reducing the likelihood of transmission.

In addition, the effectiveness of lids in preventing aerosolization of pathogens is not universally agreed upon. While some studies have found that flushing lidless toilets can spread bacteria such as Clostridium difficile (C. difficile) through aerosolized droplet nuclei, also known as "toilet plumes," there is still debate about whether these airborne particles can transmit diseases. The disagreement stems from the challenge of obtaining evidence that solely small droplets are capable of transmitting diseases, as individuals typically come into contact with both small and large droplets.

However, recent research has shown that droplet nuclei can consistently host pathogens and remain airborne for extended periods, increasing the risk of disease transmission. For example, a study found that flushing a toilet containing C. difficile released the bacteria 25 cm into the air, and it took 90 minutes for the bio-aerosol concentration to decrease significantly. This highlights the potential risk associated with lidless toilets in hospitals, especially when proper hand hygiene and infection control measures are not consistently practiced.

Lids can help avoid clogged sewer lines

Toilet lids are often missing in hospitals and public spaces. This is mainly because lids might be hard to lift for some people and they would be another surface to clean. However, lids are important because they prevent the aerosolization of pathogens, reducing the risk of infection.

The powerful current of water generated during each flush causes intense splashing and the formation and bursting of bubbles, which release two forms of droplets. Large droplets of water containing particles of waste and contagious germs are released onto the toilet seat, while smaller water droplets are released into the air and quickly evaporate, leaving behind "droplet nuclei", which are compositions of airborne waste and pathogens.

These droplet nuclei, commonly known as "toilet plumes", can transmit diseases. In one study, a toilet containing Clostridium difficile (C. diff), a bacteria that causes diarrhea and colon inflammation, released the bacteria 25 cm into the air when flushed. It took 90 minutes for the bio-aerosol concentration to decrease significantly, putting many individuals at risk of infection.

Toilet lids can help to avoid clogged sewer lines by reducing the number of these droplets and nuclei that escape into the air. When toilets are flushed with the lid down, droplets are contained within the toilet, preventing them from contaminating the surrounding area. This is especially important in hospitals where vulnerable patients are at higher risk of contracting infections.

While some argue that lids may not guarantee fewer infections and may not be worth the cost, others advocate for their installation, believing that lids are a necessary precaution to reduce the spread of diseases.
