What You'll Learn

Hospitals may have varying nail care policies
Some hospitals may have strict guidelines regarding nail care and colour, while others may be more lenient. Many nurses tend to opt for more subtle and neutral colours to maintain a professional appearance while expressing their personal style. It is important to remember that cleanliness and professionalism should always come first, and certain colours may be considered inappropriate or distracting to patients or other healthcare workers.
In addition to colour, the type of nail care and length are also important factors. Artificial nails, including acrylics, gels, and dip powder nails, have long been discouraged in nursing due to their potential to harbour bacteria and impede proper hand hygiene. However, some modern nail technologies may be more suitable for healthcare settings, and policies may vary between institutions. It is always advisable to check with a specific employer or nursing school regarding their nail care policies.
Furthermore, certain medical roles may have different rules regarding nail care. For example, doctors who are not directly involved in patient care but are primarily consulting may have more flexibility with their nail care choices. Nevertheless, it is crucial for all healthcare workers to adhere to the guidelines provided by their respective hospitals or healthcare organizations to maintain the highest standards of hand hygiene and patient safety.

Artificial nails are discouraged due to bacteria
Artificial nails, including acrylics, gels, and dip powder nails, have long been discouraged in healthcare settings due to their potential to harbour bacteria and impede proper hand hygiene. The World Health Organization (WHO) Guidelines on Hand Hygiene in Health Care from 2009 identify artificial fingernails as a risk factor, associating them with changes in normal flora and hindering effective hand hygiene.
Several studies have been conducted to investigate the link between artificial nails and bacterial infections. One study found that potential pathogens were isolated from a higher number of samples obtained from artificial nails compared to natural nails (92% vs. 62%). Over time, the colonisation of artificial nails increased, with 71% of cultures yielding a pathogen by day 15, compared to only 21% on day 1. Another study compared the microbial flora of healthcare workers (HCWs) wearing permanent acrylic artificial nails with those of HCWs with natural nails. The results showed that HCWs with artificial nails had a higher prevalence of gram-negative bacilli (47% vs. 17%) and yeasts (50% vs. 13%).
The longer artificial nails are worn, the higher the likelihood of pathogen isolation. This is because artificial nails can create an ideal environment for fungi and bacteria to grow. Nail separation can trap moisture, providing the perfect conditions for microbial growth. Additionally, cuticle abrasion, which can occur when cuticles are cut too short or become too dry, can further increase the risk of infection.
While there is no definitive scientific evidence directly linking patient infections to microorganisms transferred from artificial nails worn by healthcare workers, the potential risk is significant enough to warrant concern. As a result, many healthcare organisations have implemented guidelines restricting the use of artificial nails for healthcare workers who interact directly with patients. These guidelines are in place to ensure patient safety and maintain proper hand hygiene, which is crucial in preventing the spread of infections in healthcare settings.

Nails should be short and clean
In the healthcare profession, maintaining proper hand hygiene is crucial for both patient and personal health. Nails should be short and clean to ensure patient safety and prevent the spread of germs.
The World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC) have set guidelines for hand hygiene in healthcare workers, which include recommendations for nail care. The CDC advises healthcare workers to keep their nails short, typically no longer than one-quarter inch, or 0.5 cm, in length. This is because longer nails can harbour bacteria and other pathogens, increasing the risk of infection for patients, especially those who are immunocompromised. Additionally, long nails can puncture gloves, compromising the integrity of personal protective equipment.
Cleanliness of the nails is also essential. When washing hands, it is important to diligently clean the undersurface of the nails with soap or an alcohol-based hand rub for at least 20 seconds. This can be facilitated by using a scrub or gentle nail cleaner or brush. Proper nail hygiene is particularly critical for healthcare workers handling infected patients or infectious materials, such as during the COVID-19 pandemic.
While some hospitals may have specific policies regarding nail length and cleanliness, it is generally recommended to keep nails short and well-maintained. This may involve regular trimming and avoiding excessive cuticle cutting to maintain the natural barrier protection of the nail. In terms of nail colour, while painted nails are generally acceptable, it is advisable to choose subdued and neutral colours to maintain a professional appearance in a healthcare setting.
Overall, short and clean nails are essential in the healthcare profession to minimise the risk of spreading infections and to prioritise patient safety. Healthcare workers should adhere to their specific employer's or institution's nail care policies and guidelines to ensure they are providing the highest standards of hand hygiene.

Nail colour should be neutral and subdued
In the healthcare profession, maintaining proper hand hygiene is of utmost importance for both patient and personal health. The World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC) have set guidelines for hand hygiene, which include a brief reference to nail care.
Nail care is an important aspect of maintaining hygiene, especially during the COVID-19 pandemic. Healthcare workers (HCWs) exposed to high-risk areas in hospitals need to pay special attention to nail hygiene. Nails should be kept short and well-trimmed, with the free edge being less than 0.5 cm or 1/4 inch long. This is because long nails can harbour pathogens and bacteria on the undersurface, increasing the risk of transmitting infections to both the healthcare worker and the patient.
When it comes to nail colour, it is recommended that nurses and other healthcare workers stick to neutral and subdued colours. While some hospitals may have strict guidelines regarding nail colour, others may be more lenient. However, it is important to maintain a professional appearance while expressing personal style. Cleanliness should always come first, and more subdued and neutral colours ensure that nails won't be distracting or offensive to patients or other healthcare workers.
Some hospitals prohibit artificial nails, nail gels, and gel colours for all direct care providers. Artificial nails, including acrylics, gels, and dip powder nails, have long been discouraged in nursing due to their potential to harbour bacteria and impede proper hand hygiene. However, natural nails can also be painted, as long as the colour is neutral and subdued. It is important to avoid bright or flashy colours that may be distracting or inappropriate in a healthcare setting.

Nails should be well-trimmed
In the healthcare profession, maintaining proper hand hygiene is crucial for both patient and personal health. Patient safety is paramount, and the risk of spreading germs through improper nail care is a serious concern. Nails should be well-trimmed and kept short—ideally less than a quarter of an inch long—to reduce the risk of pathogen build-up and to prevent puncturing gloves. This is especially important for healthcare workers handling infected patients or infected material, such as during the COVID-19 pandemic.
The World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC) have set guidelines for hand hygiene, including nail care, for healthcare workers. The CDC, for instance, recommends keeping nails short and natural, particularly for those caring for patients at high risk of acquiring infections. Many healthcare facilities have expanded on these guidelines, prohibiting artificial nails, nail gels, and gel colors for all direct care providers to ensure patient safety.
Some hospitals have strict nail care policies, while others may be more lenient. It is always advisable to check with your specific employer or nursing school for their nail care policies, as they may vary between institutions. However, it is important to remember that cleanliness and professionalism should always come first. Nails that are too long can harbour bacteria and germs, increasing the risk of infection for patients.
