Long nails can harbour harmful bacteria and fungi
Long nails can pose a safety risk in various settings, including psychiatric wards, due to their potential to harbour harmful bacteria and fungi. This risk is not limited to natural nails, as artificial nails, gel nails, and nail polish also provide an environment for microorganisms to thrive.
The area beneath the fingernail, particularly the crevice, is a prime habitat for bacteria. As Jeffrey Kaplan, a biology professor at American University, explains, "The longer the nail, the more surface area there is for microorganisms to adhere." Studies have identified an astonishing variety of microorganisms under fingernails: 32 different bacteria and 28 different fungi.
The presence of these microorganisms increases the risk of transmitting diseases. Healthcare workers, for instance, are required to maintain short nails to mitigate this risk. In a tragic incident, two nurses at an Oklahoma City hospital were found to have bacteria under their long nails, which may have contributed to the deaths of 16 babies in 1997 and 1998.
While the risk of transmitting diseases is a serious concern, it is important to note that the bacteria and fungi found under nails can also lead to nail infections. These infections are not life-threatening but can cause disfigurement of the fingernails.
Maintaining nail hygiene is essential, especially for those who choose to have long nails. Regular handwashing and scrubbing can help reduce the presence of harmful microorganisms. However, as Kaplan notes, long nails can make it more challenging to thoroughly decontaminate the hands through these methods. Therefore, those with long nails should be particularly diligent about maintaining proper nail and hand hygiene to minimise the potential safety hazards associated with long nails in psychiatric and other healthcare settings.

Risk of disease transmission in psychiatric patients
Long nails can pose a safety hazard in psychiatric settings due to the risk of disease transmission. This risk is not limited to psychiatric patients but extends to anyone in close contact with individuals who have long nails, including other patients and healthcare workers.
The area under the fingernail, particularly in the crevice, is a conducive environment for microorganisms to thrive. According to Jeffrey Kaplan, a biology professor at American University, "The longer the nail, the more surface area there is for microorganisms to adhere." Studies have identified 32 different bacteria and 28 different fungi that can reside underneath fingernails. These microorganisms are challenging to eliminate through handwashing or scrubbing, increasing the likelihood of transmission.
One of the critical concerns regarding the risk of disease transmission is the presence of antibiotic-resistant bacteria, such as MRSA, which can cause severe infections in hospitalized patients. In a tragic incident reported by The New York Times, two nurses with long nails at an Oklahoma City hospital were implicated in the deaths of 16 babies in 1997 and 1998 due to the bacteria found under their nails. While a direct causal link was not established, the potential impact of long nails on disease transmission in vulnerable populations, such as psychiatric patients, cannot be overlooked.
It is worth noting that the risk of disease transmission is not limited to long artificial nails; even long natural nails can harbor bacteria and fungi. Therefore, it is essential to maintain proper hand hygiene and nail care to mitigate the risk of transmitting pathogens to others. Healthcare workers, including those in psychiatric settings, are typically required to keep their nails short to minimize the risk of transmitting infections to patients.
While the trend for long nails continues to grow, with social media platforms showcasing artistic designs, it is crucial to prioritize safety, especially in healthcare settings. Regular appointments with a nail technician can help maintain nail hygiene and strength, but it is also essential to educate individuals about the potential risks associated with long nails, particularly in vulnerable populations like psychiatric patients, where the transmission of pathogens can have severe consequences.

Potential for self-harm or injury to others
Long nails can be a safety hazard in psychiatric settings due to their potential for causing self-harm or injury to others. This is mainly due to the increased risk of harbouring and transmitting bacteria and fungi, which can lead to infections and, in severe cases, even contribute to deaths as seen in the case of two nurses in an Oklahoma City hospital.
The area under the fingernail, especially the crevice, is a prime habitat for microorganisms, and the longer the nail, the more surface area is available for these microbes to cling to and thrive. Studies have identified 32 different bacteria and 28 different fungi species underneath fingernails. This includes staphylococcus, which is commonly found on the skin and can cause infections if transmitted to the body through scratching, nail-biting, or finger-sucking.
Healthcare workers, including those in psychiatric settings, are typically required to maintain short nails to mitigate the risk of transmitting diseases. This is crucial when working with vulnerable patient populations, such as those in neonatal units, where the presence of bacteria under the nails of caregivers can have devastating consequences.
Additionally, long nails can increase the risk of accidental scratches or injuries to both the individual with long nails and those they come into contact with. In a psychiatric context, where patients may be experiencing distress or agitation, having long nails can inadvertently cause harm during moments of heightened anxiety or physical interaction.
Furthermore, the maintenance and care of long nails can be a concern. Broken nails or sharp edges can lead to inadvertent scratching or injury, especially if the individual is not accustomed to having long nails. Regular maintenance and awareness of potential hazards can help mitigate these risks.

Association with pathological grooming and OCD
Long nails can be a safety hazard in psychiatry due to their association with pathological grooming and OCD. Pathological grooming refers to a group of behaviours that include nail-biting, hair pulling (trichotillomania), and skin picking (dermatillomania or excoriation disorder). These behaviours can become uncontrollable and are often triggered by everyday activities or stress. While some psychiatrists view nail-biting as a benign habit, others consider it a form of pathological grooming that can be categorised as a body-focused repetitive behaviour.
The American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders (DSM) proposes to classify nail-biting and other pathological grooming behaviours as a form of obsessive-compulsive disorder (OCD). This reclassification is based on the idea that these behaviours are not driven by fear, but rather provide a sense of pleasure or satisfaction to the individual. By grouping pathological grooming behaviours with OCD, the DSM aims to provide new perspectives and understanding for individuals struggling with these compulsions.
Onychotillomania, a specific type of pathological grooming, involves the compulsive picking or tearing of nails. This behaviour can lead to nail bed destruction and subsequent nail disorders such as onychodystrophy and paronychia. While onychotillomania is distinct from nail-biting (onychophagia) and skin-biting, there may be overlaps and co-occurrences among these behaviours. Successful treatments for onychotillomania include the use of antipsychotics and the application of Cyanoacrylate glue on the proximal nail fold to prevent nail picking.
The presence of long nails can be a physical manifestation of pathological grooming behaviours, particularly when individuals are unable to stop biting, picking, or tearing their nails. The length of the nails may serve as a visual indicator of the severity of the underlying compulsive behaviour. Additionally, long nails can themselves become a source of anxiety or obsession for individuals with OCD or pathological grooming tendencies, as they may perceive the nails as a potential source of contamination or an impediment to their ability to function normally.
In summary, the association between long nails and pathological grooming behaviours, including OCD, highlights the potential safety hazards in psychiatry. Long nails can be a physical manifestation of underlying compulsions, providing insight into an individual's mental health struggles. Additionally, the presence of long nails can exacerbate anxiety or obsessions related to contamination and functionality, further impacting an individual's mental well-being. Understanding the connection between long nails and pathological grooming behaviours is crucial for comprehensive psychiatric care and the development of effective treatment strategies.

Impact on patient perception and therapeutic relationship
Long nails can negatively impact patient perception and the therapeutic relationship in psychiatry. This is primarily due to the increased risk of transmitting diseases caused by the bacteria and fungi that accumulate under long nails.
Healthcare workers, including psychiatrists, are typically required to maintain short nails to mitigate this risk. This requirement is based on reported incidents where bacteria under long nails may have contributed to adverse patient outcomes. For example, The New York Times reported on a case in an Oklahoma City hospital, where two nurses with long nails were implicated in the deaths of 16 babies in 1997 and 1998 due to the presence of bacteria under their nails.
The crevice under fingernails provides an ideal environment for microorganisms to thrive, and the longer the nail, the more surface area is available for these organisms to adhere to. Studies have identified 32 different bacteria and 28 different fungi species underneath fingernails. Notably, even with proper handwashing or scrubbing, it is challenging to completely decontaminate long nails, artificial nails, gel nails, acrylic nails, or nail polish.
The presence of long nails on a psychiatrist may cause patients to perceive a lack of hygiene or awareness of health and safety protocols. This perception can negatively impact the patient's trust in the psychiatrist's ability to provide safe and effective care. It may also lead to concerns about the potential risk of infection or disease transmission during in-person interactions, particularly if the patient is aware of the increased surface area for bacteria and fungi under long nails.
Therefore, maintaining short nails is essential for psychiatrists to foster a positive therapeutic relationship with their patients. It demonstrates a commitment to hygiene, safety, and the well-being of both the patient and the psychiatrist. By adhering to this simple safety measure, psychiatrists can enhance patient confidence and trust, which are fundamental to establishing a strong therapeutic alliance and facilitating effective treatment outcomes.
