The Importance of Contact Times for Disinfectants

Omidbakhsh N.

The number of hospital and community associated infections continues to rise in North America and around the world. The use of disinfectants is the backbone for infection prevention and control in healthcare, educational settings, correctional settings and emergency services. Infection Control Guidelines in North America generally state that surfaces such as countertops, over-the-bed tables, bedside tables, hand rails and other high touched surfaces be cleaned on a daily basis using an EPA or DIN registered disinfectant. However, the actual process for cleaning is rarely considered, the time needed to do the job correctly is rarely given and staffing limitations lead to inappropriate use of disinfectants.

Efficacy of Improved Hydrogen Peroxide Against Important Healthcare-Associated Pathogens

Rutala WA.

There is evidence to support that environmental contamination plays a significant role in the spread of VRE, MRSA, Clostridium difficile and Acinetobacter. These organisms have been shown to survive on environmental surfaces for days and even months causing a need for fast, safe and effective disinfectant technologies. Daily disinfection of patient care areas is often achieved in the health care environment using a one-step EPA registered hospital disinfectant such as a QUAT, however, a relatively new yet proven technology known as Accelerated Hydrogen Peroxide® (AHP®), has become a market leading chemistry that is the perfect balance between safety and efficacy.

Bacterial Contamination of Ultrasound Probes at a Tertiary Referral University Medical Center

Chu K. et al.

Healthcare-associated infections (HAIs) are among the leading causes of death in the United States. Although HAIs may seem irrelevant to radiology, ultrasound examinations may be an unaccounted contributing factor for their development. There are established guidelines for disinfection and sterilization in general, but a lack of compliance and misuse of disinfectants has led to numerous outbreaks. According to the CDC, there are seven factors affecting the efficacy of disinfection which in turn impacts compliance: the number and location of microorganisms, innate resistance of microorganisms, concentration and potency of disinfectants, physical and chemical factors, presence or absence of organic and inorganic soils and the presence or absence of biofilms. Accelerated Hydrogen Peroxide® (AHP®) is a synergistic blend of commonly used, safe ingredients that has unparalleled germicidal efficacy and has been proven to reduce HAIs.

Experts Partner to Address Resistant Bacteria Through Antibiotic Stewardship, Environmental Hygiene

Alfa, J. et al. | Infection Control Today, 2015

Antibiotic resistance has become a significant topic of importance as antibiotic resistance threatens the effective prevention and treatment of an ever-increasing range of infections caused by bacteria. As an increasingly serious global threat, public health has required action across all government sectors and society. Infection Control Today partnered with Dr. Stuart Levy and Dr. Rosie Lyles to share their perspectives on antibiotic resistance and how environmental surfaces and disinfectants play a role.

Improved Eradication of Clostridium Difficile Spores From Toilets of Hospitalized Patients Using an Accelerated Hydrogen Peroxide as the Cleaning Agent

Alfa M.J. et al.

Clostridium difficile associated diarrhea (CDAD) is a significant problem in healthcare facilities world-wide. Since 2000 there has been an increase in the rates of C. difficile in some health care settings. This increase in CDAD has resulted in significant additional costs to the healthcare system. According to one study, in U.S. hospitals it is estimated that each case of CDAD in a hospital was associated with $3699.00 (USD) in excess healthcare costs and 3.6 extra days of hospitalization. The use of Accelerated Hydrogen Peroxide® (AHP®) in this study shows that it is a useful alternative to bleach where C. difficile spores may exist. Unlike most disinfectant technologies, AHP is a very good cleaner, as well as a fast acting bactericidal and virucidal agent which simplifies the cleaning protocol for Environmental Services Staff as only one product needs to be used.

Minimizing the Risk of Bacterial Transmission from Patient to Patient When Using Duodenoscopes

Virox Technologies Inc. | PIDAC (2016).

This document was developed by the Provincial Infectious Diseases Advisory Committee (PIDAC) as an extension to the Best Practices for Cleaning, Disinfection and Sterilization of Medical Equipment/Devices in All Health Care Settings guideline. Recent outbreaks have demonstrated that adherence to current guidelines for endoscope reprocessing may not be sufficient to prevent bacterial transmission following the use of duodenoscopes. This document reviews the recommended cleaning and disinfection practices for reprocessing duodenoscopes which have been based on theoretical consideration and expert opinion.

Effects of mandatory continuing education related to infection control on the infection control practices of dental hygienists

Kelsch et al.

The scope of work within dental settings has many infection control risks. As such, compliance with infection control recommendations and requirements is critical to the delivery of quality dental care and necessary to ensure the safety of both patients and clinicians in the dental setting. Practice acts in 18 states require that dental hygienists complete infection control continuing education for license renewal, whereas the other states do not have this requirement. The purpose of this study was to assess the effects of mandatory continuing education related to infection control on the infection control practices of dental hygienists.

pH: Is it an appropriate indicator of product safety?

There is much confusion among cleaning and disinfectant users regarding pH and what it means with respect to a product’s cleaning or killing properties, its materials compatibility as well as its rating with regards to its toxicity / hazard profile. The intent is to dispel these misunderstandings and provide the facts to help increase your confidence in your choice of cleaning or disinfectant chemistry.

Comparison of disinfectant efficacy when using high-volume directed mist application of accelerated hydrogen peroxide and peroxymonosulfate disinfectants in a large animal hospital.

Saklou N, Burgess B, Van Metre D, Hornig K, Morley P, Byers S.

Effective decontamination of animal holding environments is critical for providing high quality patient care and maintaining a safe working environment. Disinfection of animal holding environments is a significant challenge during times of epidemic disease. This study considers a relatively new yet proven technology Accelerated Hydrogen Peroxide® (AHP®) in the battle against microbes, as an alternative to legacy disinfectant chemistries with known shortcomings

Understanding the Essentials of Germicidal UV Light

Virox Technologies Inc. | Infection Control Today, 2015

Healthcare facilities wanting to supplement their existing environmental hygiene strategies are exploring how ultraviolet light can bolster manual cleaning and disinfection practices. Experts emphasize that a comprehensive multi-modal approach to environmental cleaning is imperative and that the technology should be an adjunct intervention to routine manual cleaning and disinfection protocols. As Barbut (2015) emphatically states, “The new no-touch methods for room disinfection supplement, but do not replace daily cleaning”.
