Hand Sanitizer: Reducing Hospital-Associated Illnesses?

Hand sanitizers are an increasingly popular method of hand hygiene and are used to prevent hospital-acquired infections. Hand sanitizers can be used both outside and inside healthcare facilities as they effectively kill most microorganisms. However, in hospitals, bacterial species are becoming increasingly tolerant of the alcohols used in hand sanitizers. This has led to a debate about whether hand sanitizers decrease hospital-associated illnesses or not.

Hand sanitizer dispensers can become contaminated with pathogens

Another study conducted sampling from operational automatic hand sanitizer dispensers (HSDs) in a surgical intensive care unit. The dispenser lever, the rear underside, and the area surrounding the dispensing nozzle were cultured, and all HSDs yielded one or more bacterial species, including commensal skin flora and enteric gram-negative bacilli. Colonization was greatest on the lever, where there is direct hand contact.

The use of hand sanitizers is an important tool in preventing the spread of HAIs. Alcohol-based hand sanitizers are increasingly used instead of soap and water for hand hygiene in healthcare settings due to their ease of use, increased availability, and proven effectiveness. Hand sanitizers effectively kill most microorganisms and improve hand hygiene, reducing the transmission of microorganisms in hospital settings.

However, the effectiveness of hand sanitizers in hospitals may be limited by the emergence of alcohol-resistant bacterial strains. Research has found that one bacterial species in hospitals is becoming increasingly tolerant of the alcohols used in hand sanitizers. This highlights the importance of proper hand hygiene and the need for additional control measures, such as using bacteria-killing agents like chlorhexidine, to sanitize hands in some medical care settings.

Overall, while hand sanitizer dispensers can become contaminated with pathogens, the use of hand sanitizers is still an important tool in preventing the spread of HAIs when combined with proper hand hygiene techniques and education.

Hand sanitizers are less effective against some hospital germs

Hand sanitizers are a popular method of hand hygiene and can be used to prevent hospital-acquired infections. They are effective in killing most microorganisms and reducing infection rates. However, a 2018 study found that hand sanitizers are becoming less effective against some hospital germs.

The study, covered by CNN, revealed that in hospitals, one bacterial species is becoming increasingly tolerant of the alcohols used in hand sanitizers. This finding refutes the long-held assumption that rubbing alcohol was safe from the emergence of resistance among susceptible germs. The study's co-author, Paul Johnson, an infectious diseases professor and director of research, suggested that hospitals might need to implement additional control measures, such as using an extra bacteria-killing agent like chlorhexidine, to sanitize hands in certain medical settings.

The reduced effectiveness of hand sanitizers against specific hospital germs is a concern, especially considering the critical role of hand hygiene in preventing healthcare-associated infections. Compliance with hand hygiene recommendations is essential to reducing colonization and infection, particularly among healthcare workers. Proper hand hygiene can decrease the transmission of microorganisms to patients and lower morbidity, mortality, and costs associated with healthcare-associated infections.

While the 2018 study highlights a potential issue with hand sanitizer effectiveness, it is important to note that hand sanitizers still offer excellent coverage against most pathogens. They are widely used in various settings, including clinics, hospitals, acute care facilities, and the community in general. Hand sanitizers are preferred over soap and water for cleaning hands in most clinical situations, as they are easy to use and accessible.

To optimize the benefits of hand sanitizers and address the challenges posed by certain bacteria, hospitals can consider implementing a combination of strategies. This may include promoting proper hand hygiene techniques, providing education and training, ensuring compliance among healthcare workers, and exploring additional control measures such as supplementary bacteria-killing agents. By taking a comprehensive approach, hospitals can maximize the effectiveness of hand sanitizers while mitigating the impact of germs that may be resistant to standard sanitization methods.

Hand sanitizers are increasingly used instead of handwashing

Hand sanitizers are increasingly being used as an alternative to handwashing, especially in healthcare settings. Alcohol-based hand sanitizers are preferred over soap and water for cleaning hands in most clinical situations, even when caring for patients with C. difficile infection (CDI). This is because alcohol-based sanitizers effectively kill most microorganisms, including bacteria and viruses, and are more convenient and accessible than handwashing.

The ease of use, increased availability, and proven effectiveness of hand sanitizers make them a popular choice for hand hygiene. Their ability to kill most non-spore-forming bacteria within seconds contributes to their effectiveness in reducing infection rates. In one study, the use of an alcohol gel hand sanitizer by caregivers in an extended care facility resulted in a 30.4% decrease in infection rates over a 34-month period.

Hand sanitizers are particularly advantageous when handwashing is not practical or feasible. They can be used both inside and outside healthcare facilities, making them a versatile option for hand hygiene. Additionally, patients and healthcare workers can be provided with portable bottles of hand sanitizer for bedside use, further enhancing their accessibility.

However, it is important to note that hand sanitizers should not replace handwashing entirely. Handwashing with soap and water is still essential, especially when hands are visibly soiled. Proper handwashing techniques, such as avoiding hot water and patting hands dry, are crucial to maintaining healthy hand skin and preventing the spread of germs.

Furthermore, while hand sanitizers are effective in reducing certain types of infections, they may be less effective against specific bacterial species. For example, research has shown that some bacteria in hospitals are becoming increasingly tolerant of the alcohols used in hand sanitizers. Therefore, a combination of handwashing and the use of hand sanitizers, along with proper hygiene education, is recommended to maximize the reduction of bacteria and viruses on hands.

Hand sanitizers are critical to reducing colonization and infection

Alcohol-based hand sanitizers are particularly effective in killing most non-spore-forming bacteria and decreasing infection rates. They are widely used in various settings, including hospitals, clinics, and community settings, due to their high antimicrobial efficacy, ease of use, and availability. The use of alcohol gel hand sanitizers has been shown to significantly reduce infection rates in multiple studies, with one study demonstrating a 30.4% decrease in infection rates over a 34-month period. Another study in an acute care facility found a 36.1% decrease in infection rates during a 10-month period when alcohol hand sanitizer was used.

However, it is important to note that hand sanitizers should be used correctly and at the right time to maximize their effectiveness. Additionally, promoting hand hygiene should be accompanied by hygiene education and the promotion of other aspects of hygiene to optimize health benefits. Hand sanitizers also have limitations, such as skin reactions and dryness, and may not be suitable for those with severe allergic reactions to alcohol.

While hand sanitizers are effective, it is worth noting that in hospitals, some bacterial species are becoming increasingly tolerant of the alcohols used in hand sanitizers. This highlights the importance of compliance with hand hygiene recommendations and the potential need for additional control measures, such as using other bacteria-killing agents in certain medical care settings.

In conclusion, hand sanitizers play a critical role in reducing colonization and infection, especially in healthcare settings, by improving hand hygiene and reducing the transmission of microorganisms. However, their effectiveness depends on proper usage, education, and awareness, along with the implementation of additional measures to address the evolving resistance of certain bacterial species.

Hand sanitizers are an effective tool in an infection control program

The use of hand sanitizers can significantly reduce the transmission of healthcare-associated pathogens and the incidence of healthcare-associated infections (HCAIs). HCAIs pose a significant global burden, affecting over 1.4 million patients worldwide at any given time. Hand sanitizers, therefore, play a crucial role in reducing morbidity, mortality, and healthcare costs associated with HCAIs.

Studies have shown that the use of alcohol gel hand sanitizers can decrease infection rates. For example, a study conducted at an extended care facility in Columbus, Ohio, found a 30.4% decrease in infection rates over a 34-month period in units where hand sanitizer was used compared to control units that did not use hand sanitizer. Similarly, another study conducted at an acute care facility demonstrated a 36.1% decrease in infection rates over a 10-month period when hand sanitizer was utilized.

However, it is important to note that hand sanitizers should not be solely relied upon. Handwashing with soap and water is still essential, especially when hands are visibly soiled. Additionally, promoting hand hygiene compliance among healthcare workers and the general public is crucial. Proper hand hygiene techniques and education about the correct times to perform hand hygiene can further enhance the effectiveness of hand sanitizers in infection control programs.

While hand sanitizers are a valuable tool, it is worth mentioning that alcohol-based hand sanitizers may be less effective against certain bacterial species in hospitals, as some organisms can develop resistance over time. This emphasizes the need for ongoing research and the potential requirement for additional control measures in specific medical care settings.
