Let Bactiscan Show You Where The Bacteria Really Is! – Biofilmdetect

Fluorescence Image Guided Healthcare Infection Prevention

Healthcare-associated infections result in poor patient outcomes, including prolonged hospital stays, increased morbidity, and mortality.

In the United States, 75 000 patients die every year from healthcare-associated infections(HAIs). These infections are often caused by multidrug-resistant organisms, with Clostridium difficile being the most common.

These multidrug-resistant organisms in the hospital environment are challenging to detect and are often inadequately disinfected.

Therefore, patients who enter contaminated hospital rooms are more likely to acquire and contract these multidrug-resistant organisms(MDROs).

It is also well documented that healthcare workers play a critical role in transmitting pathogens from patient to patient.

Additionally, the contaminated environment is increasingly thought to play a significant role in pathogen transmission.

Disinfecting high-touch surfaces is especially important because they can be reservoirs for infectious agents and cause the spread of multidrug-resistant organisms.

In addition, it is believed that high-touch surfaces near patients have a higher bioburden. This can lead to secondary transmission from direct contact with the patient or via the hands of healthcare workers and visitors.

It has been shown that cleaning and disinfection in healthcare environments reduce the incidence of healthcare-associated infections.

Therefore, environmental cleaning and disinfection are essential components of a comprehensive strategy to eliminate HAI, especially in units with immunocompromised patients.

In recent years, decontamination of the environment, such as patient-care rooms before admission of subsequent occupants, has become more critical, and high-touch sites are recommended to be cleaned and disinfected more frequently than low-touch sites.

However, despite improved cleaning interventions, more than 5–30% of surfaces remain potentially contaminated since existing detergent formulations and disinfectants fail to disrupt biofilms.

Furthermore, this high-touch site-focused cleaning may contribute to inadequate decontamination of the hospital environment. Because, if high-touch sites have a high bio-burden, there will also be cross-contamination of the low-touch areas. 

Consequently, the infrequently low-touch sites will also become reservoirs of epidemiologically significant pathogens that can contribute to hospital-wide spread of MDROs.

The successful elimination of HAI will require an all-touch-site strategy that incorporates technology to scan all surfaces to detect the locations of bacteria, mold, and biofilm, to optimize cleaning and disinfection of those sites.

Bactiscan’s innovative fluorescence image guided technology can instantly identify the locations of bacteria, biofilm and mold on a variety surfaces across large areas, making it an ideal tool for an all-touch-site strategy to eliminate HAI.



Fluorescence Image Guided Solutions For Biofilms Eradication

Biofilm formation by bacteria appears to be an important factor in causing HAI. It is thought that approximately 99% of the world’s known bacterial population resides in biofilms.

The US’s National Institutes of Health (NIH) estimates that about 80% of all chronic infections are due to biofilm formation.

Microorganisms live in biofilms composed of cells adhered to surfaces and each other, creating a micro-colony surrounded by a polysaccharide matrix.

An interesting feature of a biofilm is that it contains not only cells but also DNA, proteins, and biosurfactants.

The adhesive properties of bacterial biofilms and their use of extracellular polymeric substances (EPS) make biofilms persistent on surfaces.

The EPS forms an incredibly difficult matrix to remove from surfaces in healthcare facilities.

Furthermore, it is “resistant” to physical stress and shields bacterial cells from direct contact with disinfectants.

As a result of the EPS matrix, bacteria in biofilms are about 1,000 times less susceptible to disinfectants than their free-floating counterparts.

Additionally, the water-binding ability of the EPS matrix and the pH differences among the various biofilm layers also affect the ability of disinfectants to penetrate the biofilm matrix.

This may cause the aggregation of organic acids, which in turn may lead to the inactivation or degradation of less potent disinfectants.

Despite repeated cleaning, bacterial biofilms can accumulate on wet and dry surfaces in the hospital environment for up to 12 months.

It has been shown that hospital surfaces are a significant source of pathogen transmission.

Biofilms on dry surfaces are prevalent and contain pathogens and multidrug-resistant organisms (MROs).

The presence of biofilm on highly touched surfaces poses a threat to patients, as dry surface biofilms can persist for long periods of time, and microorganisms contained within biofilms have been found to be transferrable.

Biofilms created by these microbes and MROs on a range of surfaces are extraordinarily resistant to cleaning, disinfection, and antibiotics.

Furthermore, the bacteria within biofilms are remarkably resistant to antibiotics and disinfectants.

The formation of biofilms may contribute to the persistence of environmental contamination in hospitals and healthcare facilities.

Using Bactiscan, you can visualize biofilms on surfaces in real-time, seeing the green glow of the bacteria proteins fluorescing before your eyes.

Bactiscan fluorescence image-guided system instantly identifies biofilms on a variety of surfaces across large areas, making it ideal for helping to guide effective mitigations, to eradicate biofilms from surfaces.

Creating Bactiscan Clean Emergency Medical Services

Emergency Medical Services (EMS) are at the front line of the healthcare system’s emergency response. As first-responders or patient transporters, they can encounter infectious disease, blood, and bodily fluids on a daily basis.

In order to ensure the safety of their patients, their ambulances, medevacs, and apparatuses must be effectively cleaned and sanitized to prevent contamination and the spread of infection. Bactiscan Cleaning Verification enables EMS providers to quickly and efficiently measure the effectiveness of cleaning practices and offer actionable data to alert staff of problem areas, evaluate cleaning methods, and set goals for improvement.



Creating Bactiscan Clean In Environmental And Domestic Services

While the cleaning methods, sanitisers, and equipment used in healthcare facilities vary, the need to measure the effectiveness of cleaning practices is universal.

Environmental Services managers need quick and actionable data to measure the performance of cleaning staff to ensure that cleaning has been completed according to standards.

The Bactiscan can be used as a complementary environmental cleanliness monitor, to troubleshoot problem areas in the hospital, evaluate cleaning methods and procedures, and set goals for improvements.


Creating Bactiscan Clean Healthcare Laundry Facilities

Improperly laundered healthcare textiles carry harmful pathogens that contribute to the spread of hospital-acquired infections and pose a risk to vulnerable patients, visitors, and healthcare workers.

By using Bactiscan cleaning verification, healthcare laundry facilities can test surfaces and fabrics to ensure that their textiles are adequately cleaned and help fight the spread of deadly infections.



Creating Bactiscan Clean In Infection Control

Infection control departments have significant responsibilities in ensuring that cleaning standards are maintained at the highest levels.

The coordination of the Infection Control department with Environmental Services plays a crucial role in maintaining a clean hospital to prevent healthcare-acquired infections by ensuring that cleaning standards are upheld while keeping a tight budget.

Objective measurement of surface cleanliness using Bactiscan cleaning verification provides a rapid assessment of cleaning effectiveness and informs Infection Control managers to know how cleaning staff is performing, and quantify the standard of cleanliness in the healthcare environment. In addition, the Bactiscan cleanliness audits can be used to set goals for improvement and keep every member of the team cleaning to the same, measurable standard.
