Hospitals have strict policies regarding the physical appearance of their employees, especially nurses, to maintain hygiene and safety. One of the most controversial rules is the ban on gel nails and artificial nails. This is because artificial nails, including gel manicures, can harbor bacteria and are difficult to clean effectively, making them a potential source of infection for patients. Studies have shown that hospital staff with artificial nails can have higher levels of bacteria even after hand washing compared to those with natural nails. Additionally, long nails, whether natural or artificial, can tear medical gloves and spread bacteria through physical contact with patients, equipment, and surfaces. These concerns have led to hospitals prohibiting gel nails and artificial nails for their employees, with some hospitals even banning all forms of nail polish.

Gel nails can interfere with medical equipment
The endurance of gel nails can complicate medical care and interfere with medical equipment. Gel nails are difficult to clean effectively, making them a breeding ground for bacteria. A 1989 study in the "American Journal of Infection Control" found that artificial nails, including gel nails, harbored higher counts of gram-negative bacteria, such as Enterobacter, Serratia, Klebsiella, and Pseudomonas, even after hand washing. These types of bacteria are more complex to kill and are responsible for hospital-acquired infections. As a result, the CDC and WHO guidelines recommend that direct care providers should not have artificial nails or extenders, and many organizations have expanded this ban to include gel nails as well.
The thickness of gel nails can interfere with medical equipment such as pulse oximeters, which are commonly used in emergency rooms and hospitals to measure oxygen levels in the blood. Pulse oximeters rely on infrared and red light to get an almost instantaneous reading, and the thickness of gel nails can impact the accuracy of these measurements. In some cases, even regular nail polish, if dark enough, can affect the reading. As a result, ambulances and emergency rooms routinely stock nail polish remover to address this issue.
The subungual region, which includes the area under the fingernails, can harbor microorganisms that can be difficult to remove with hand washing alone. Artificial nails, including gel nails, can increase the risk of tearing gloves, as the nails may extend past the fingertips. This can lead to a higher risk of infection and the transmission of bacteria to patients. Additionally, long fingernails, whether natural or artificial, may scratch or cause discomfort to patients during moving or positioning.
To ensure the safety of patients and comply with infection control protocols, hospitals have implemented policies prohibiting healthcare workers from having gel nails. These policies are based on scientific studies and are designed to minimize the risk of infection and the spread of bacteria. While some nurses may find these policies restrictive, the priority is to maintain a sterile environment and provide the best possible care to patients.

Artificial nails can harbour bacteria
Artificial nails, including gel manicures, are not allowed in hospitals because they can harbour bacteria, even after hand washing. The subungual region, or the area under fingernails, is where most microorganisms on the hand are found. Artificial nails, which are superficially adhered to the nail bed, can develop cracks that allow bacteria to invade and multiply.
A 1989 study in the "American Journal of Infection Control" found that artificial nails had higher counts of gram-negative bacteria, such as Enterobacter, Serratia, Klebsiella, and Pseudomonas, even after hand washing. These types of bacteria are more complex to kill and are responsible for hospital-acquired infections. Additionally, long fingernails, whether artificial or natural, can tear gloves more easily and may scratch or gouge patients during movement or positioning.
The Hospital Infection Control Practices Advisory Committee has recommended eliminating artificial nails for healthcare workers in its guidelines for hand hygiene, grading it as the highest category of importance. The CDC and WHO have also provided guidelines regarding artificial nails, with the WHO prohibiting artificial nails and extenders for all healthcare workers, and the CDC recommending against their use in high-risk areas.
Many hospitals have adopted policies prohibiting artificial nails and certain manicures, such as gel polish, to prevent the spread of infections. However, the enforcement of these policies has been challenging, and some healthcare providers continue to have artificial nails or gel manicures.

Long nails can tear gloves
Long nails, whether natural or artificial, can cause gloves to tear more easily. The subungual region, or the area under the fingernail, is where most microorganisms on the hand are found. As nails get longer, more debris accumulates, and removing this debris requires vigorous scrubbing and running water. Nails that extend past the fingertips can also scratch or gouge patients during movement or positioning.
In addition to being difficult to clean, long nails can also harbour bacteria and other organisms, which can lead to infections. Studies have shown that hospital staff with long nails, especially those with artificial nails, tend to have higher levels of bacteria even after hand washing compared to those with short, natural nails. This is because cracks can form in artificial nails, providing an entry point for bacteria to invade and multiply.
The risk of tearing gloves is, therefore, higher for those with long nails, and this can have serious consequences for both the wearer and the patient. Tearing gloves can expose the wearer's hands to bacteria and other contaminants, compromising hand hygiene. It can also put patients at risk of infection if the person wearing the torn gloves comes into contact with them or the surrounding environment.
As a result, many hospitals have implemented policies that require staff to maintain short, natural nails and prohibit the use of artificial nails or nail extensions. These policies are in place to ensure the safety of both patients and healthcare workers and to reduce the risk of infection and the transmission of microorganisms.
While some may view these policies as restrictive, the priority is to maintain a safe and hygienic environment in hospitals. Hand hygiene is crucial in healthcare settings, and long nails, whether natural or artificial, can compromise the effectiveness of handwashing and increase the risk of tearing gloves.

Nails can spread hospital-acquired infections
Studies have shown that hospital staff with nail enhancements tend to have more bacteria on their hands, even after washing them, than those with natural nails. This is because cracks can form in artificial nails, allowing bacteria to invade and multiply. In addition, it is harder to thoroughly clean longer nails, as this requires vigorous scrubbing and running water. The higher risk of tearing gloves is another issue, as this may expose the wearer to harmful substances.
The Journal of the American Academy of Dermatology published a study that found that nurses with artificial nails had higher counts of gram-negative bacteria, such as Enterobacter, Serratia, Klebsiella, and Pseudomonas, which are responsible for hospital-acquired infections. Gram-negative bacteria are harder to kill than gram-positive bacteria. This is a serious concern, as it means that nails could be contributing to the spread of harmful bacteria.
Furthermore, artificial nails have been directly linked to outbreaks of hospital-acquired infections. For example, an outbreak of P. aeruginosa in an ICU was linked to two nurses, one with artificial nails and the other with long, natural nails. In another instance, three laminectomy patients developed post-operative Candida diskitis, which was traced back to an operating room technician with artificial nails.
As a result of these concerns, many hospitals have implemented policies prohibiting employees from having artificial nails or certain manicures. These policies are in place to prevent the spread of hospital-acquired infections and protect the health and safety of patients and staff.

Hospitals ban all nail polish
Hospitals have strict infection control protocols in place to ensure the safety of patients and staff. As part of these protocols, many hospitals have implemented bans on all nail polish, including gel nails. While gel nails are popular due to their longevity and aesthetic appeal, they pose several risks in a healthcare setting.
Firstly, gel nails are considered artificial nails or nail enhancements, which are known to harbour bacteria. Studies have shown that hospital personnel with artificial nails can have higher levels of bacteria on their fingertips, even after hand washing, compared to those with natural nails. The thick layer of gel polish creates a perfect environment for bacteria to hide and multiply, as it adheres to the nail bed and forms tiny cracks that bacteria can invade and fester in. This can increase the risk of transmitting infections to patients, particularly in high-risk areas.
Additionally, long nails, whether natural or artificial, can tear medical gloves more easily and may cause scratches or gouges during patient care procedures. This can compromise the integrity of sterile environments and increase the risk of infection. Furthermore, in emergency situations, thick gel nails or dark-coloured nail polish can interfere with medical devices such as pulse oximeters, which are used to measure oxygen levels in the blood. This interference can lead to inaccurate readings and potentially impact patient care decisions.
While some nurses may express disappointment with these bans, as they value their manicured nails, hospitals prioritise patient safety and adhere to guidelines set by organisations like the CDC and WHO. These organisations recommend against the use of artificial nails and nail gels for healthcare workers to minimise the risk of infection and maintain high standards of hand hygiene. As a result, hospitals implement these bans to ensure compliance with industry standards and protect the well-being of their patients.
