Effectiveness of a Hydrogen Peroxide Mist (Trophon) System in Inactivating Healthcare Pathogens on Surface and Endocavitary Probes

Implementation of a light therapy team to administer photobiomodulation therapy: A standardized protocol to prevent and treat oral mucositis in the pediatric hematopoietic stem cell transplant population

BACKGROUND

Oral mucositis (OM) is a painful and common complication of hematopoietic stem cell transplant (HSCT). The Children's Oncology Group recently published guidelines recommending photobiomodulation (PBM) for preventing and treating OM in pediatric HSCT patients. However, this is a rarely used intervention in pediatric hospitals.

PROCEDURE

Patients undergoing allogeneic HSCT, or autologous HSCT for a neuroblastoma diagnosis, had PBM administered from the first day of conditioning to transplant Day +20. We successfully developed a standardized treatment protocol and workflow to ensure consistent and uniform delivery of PBM. In addition, clinical patient data were compared before and after PBM implementation.

RESULTS

The administration of PBM at our center was feasible, but required dedicated staff. A registered nurse (RN) was determined to be the best fit to deliver PBM. Sixty-two patients received PBM from October 2022 to September 2023; patients from 2021 before PBM implementation were used for comparison. Patients receiving PBM were more likely (p = .03) to engage in teeth brushing (56/62 = 90%) compared to baseline (61/81 = 75%). Mean days of OM decreased from 11.3 to 9 days; patients who received PBM were less likely (p < .001) to be discharged on total parental nutrition (TPN) (11/62 = 18%) compared to baseline (50/82 = 61%). OM-related supportive care costs (TPN and patient-controlled anesthesia [PCA]) were lower (p = .02) for those who received PBM (median cost = $31,229.87 vs. $37,370.66).

CONCLUSION

PBM, as the standard of care in the pediatric HSCT population, is safe, feasible, and well-tolerated. At our center, a dedicated RN was critical to providing standardized treatment and ensuring sustainability.

The need for participation in the development and critical review of recommendations for infection control policies involving vascular ultrasound

Recently reported guidelines from the Society of Diagnostic Medical Sonography regarding disinfection of ultrasound probes and infection control policies for ultrasound procedures conflict with accepted clinical norms in vein practices and recommendations from the American Institute for Ultrasound in Medicine. We have provided a review of these conflicting policy recommendations and new proposed practice recommendations and a call for physicians who perform ultrasound-guided procedures to be involved in the process of development and critical review of societal recommendations.

Reprocessing semicritical items: Outbreaks and current issues

Semicritical medical devices are defined as items that come into contact with mucous membranes or nonintact skin (eg, gastrointestinal endoscopes, endocavitary probes). Such medical devices require minimally high-level disinfection. As many of these items are temperature sensitive, low-temperature chemical methods must be used rather than steam sterilization. Strict adherence to current guidelines is required as more outbreaks have been linked to inadequately cleaned or disinfected endoscopes and other semicritical items than any other reusable medical devices.

Reviewing the Use of Glutaraldehyde for High-level Disinfection by Sonographers

A review of recent literature has demonstrated that ultrasound transducers may harbor bacteria and viruses that could cause cross-contamination for patients. Reducing the risk of cross-contamination is achieved by high-level disinfection of ultrasound transducers. One of the main types of high-level disinfectants (HLD) used in performing sonography is glutaraldehyde (GA). While GA-based HLDs are cleared in abundance by the FDA and compatible with most transducers, GA has been reported to cause extensive adverse effects and has limited efficacy as a disinfectant. This literature review provides a current set of studies that discuss high-level disinfection of ultrasound transducers, GA use, exposure, and alternatives. This information could be used by practitioners to carefully consider how to effectively clean ultrasound transducers and supporting equipment. Additional guidance is provided on how to potentially minimize GA exposure and suggestions for protecting patients during their imaging examination.

The Role of Patient Care Items as a Fomite in Healthcare-Associated Outbreaks and Infection Prevention

Patient-care items can serve as a source or reservoir for healthcare-associated pathogens in hospitals. We reviewed healthcare- associated outbreaks from medical equipment and provide infection prevention recommendations. Multiple healthcare-associated outbreaks via a contaminated patient-care item were identified, including infections with multidrug-resistant organisms. The type of patient care items implicated as a fomite causing healthcare-associated infections (HAIs) has changed over time. Patient populations at risk were most commonly critically ill patients in adult and neonatal intensive care units. Most fomite related healthcare-associated outbreaks were due to inappropriate disinfection practices. Repeated healthcare-associated outbreaks via medical equipment highlight the need for infectious disease professionals to understand that fomites/medical devices may be a source of HAIs. The introduction of new and more complex medical devices will likely increase the risk that such devices serve as a source of HAIs. Assuring appropriate cleaning and disinfection or sterilization of medical equipment is necessary to prevent future fomite-associated outbreaks.

Disinfection and Sterilization in Health Care Facilities: An Overview and Current Issues

When properly used, disinfection and sterilization can ensure the safe use of invasive and noninvasive medical devices. The method of disinfection and sterilization depends on the intended use of the medical device: critical items (contact sterile tissue) must be sterilized before use; semicritical items (contact mucous membranes or nonintact skin) must be high-level disinfected; and noncritical items (contact intact skin) should receive low-level disinfection. Cleaning should always precede high-level disinfection and sterilization. Current disinfection and sterilization guidelines must be strictly followed.
