time effectiveness of ultraviolet c light uvc emitted by light emitting diodes leds in reducing Stethoscope contamination
International Journal of Environmental Research and Public Health, 2016Co-Authors: Gabriele Messina, M Fattorini, Nicola Nante, D Rosadini, Andrea Serafini, Marco Tani, Gabriele CeveniniAbstract:Today it is well demonstrated that Stethoscopes can be as contaminated as hands, which are a recognized source of Health-Care Associated Infections (HCAIs). Ultraviolet C (UVC) light has proven disinfection capacity and the innovative UVC technology of Light Emitting Diode (LED) shows several potential benefits. To verify whether the use of UVC LEDs is effective and reliable in Stethoscope membrane disinfection after prolonged use, a pre-post intervention study was conducted. A total of 1668 five-minute cycles were performed on two UVC LEDs to simulate their use; thereafter, their disinfection capacity was tested on Stethoscope membranes used on a previously auscultated volunteer. Then, a further 1249 cycles were run and finally the LEDs were tested to assess performance in reducing experimental contamination by Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli on the Stethoscope membrane. Baseline volunteer contamination identified 104 Colony Forming Units (CFUs) while treated Petri dishes had 12 and 15 CFUs (p < 0.001). Statistically significant differences (p < 0.001) were also found relating to the reduction of specific bacteria: in particular, after treatment no CFU were observed for S. aureus and E. coli. UVC LEDs demonstrated the capacity to maintain high levels of disinfection after more than 240 h of use and they were effective against common microorganisms that are causative agents of HCAIs.

a new uv led device for automatic disinfection of Stethoscope membranes
American Journal of Infection Control, 2015Co-Authors: Gabriele Messina, Sandra Burgassi, Daniele Messina, Valerio Montagnani, Gabriele CeveniniAbstract:Background Stethoscopes are widely used by doctors and nurses. Poor Stethoscope hygiene is a potential source of nosocomial infection. This study aimed to propose an innovative solution, based on the latest advances in ultraviolet (UV) light-emitting diodes (LEDs), for disinfecting Stethoscope membranes automatically and efficiently. Methods Staphylococcus aureus , Escherichia coli , Pseudomonas aeruginosa , and Enterococcus faecalis were sown on 28 Stethoscope membranes and then transferred to Petri dishes. Treatment involved illuminating exposed Petri dishes with a UVC LED for 1 minute. For each microbe, the number of colony-forming units (cfu) at 36°C was compared in control and treated dishes using the Wilcoxon signed-rank test. The Kruskal-Wallis test was used to assess percent reductions in bacteria. Statistical significance was set at 99%. Results A significant reduction in cfu counts after UV treatment ( P E faecalis , 87.5% for S aureus , 94.3% for E coli , and 94.9% for P aeruginosa . No significant differences in percent reduction in cfu were found between bacteria ( P > .01). Conclusion The Stethoscope, symbol of medicine and health care professionals, has been demonstrated to be a carrier of microorganisms. The treatment technique was effective and efficient in disinfecting the membranes. These promising results represent a step forward toward eliminating Stethoscope membrane contamination with an innovative approach.

A wearable UV-LED medical device for automatic disinfection of Stethoscope membrane
European Journal of Public Health, 2014Co-Authors: Gabriele Messina, Sandra Burgassi, Daniele Messina, Valerio Montagnani, Gabriele CeveniniAbstract:Background The medical literature has demonstrated the importance of healthcare-associated infections (HAIs) and their negative consequences which are often due to inadequate management of cleaning, disinfection and sterilization. Stethoscope is the most used medical device in the world. The lack of Stethoscope hygiene favors the transmission of microorganisms and can be a potential source of HAIs. This study proposes and evaluates an innovative health technology solution for Stethoscopes’ disinfection. Methods A prototype of a portable and …

Improving Stethoscope disinfection at a children's hospital.
Infection Control and Hospital Epidemiology, 2013Co-Authors: Justin Zaghi, Jing Zhou, Dionne A. Graham, Gail Potter-bynoe, Thomas J. SandoraAbstract:Objective. Stethoscopes are contaminated with pathogenic bacteria and pose a risk for transmission of infections, but few clinicians disinfect their Stethoscope after every use. We sought to improve Stethoscope disinfection rates among pediatric healthcare providers by providing access to disinfection materials and visual reminders to disinfect Stethoscopes.Design. Prospective intervention study.Setting. Inpatient units and emergency department of a major pediatric hospital.Participants. Physicians and nurses with high anticipated Stethoscope use.Methods. Baskets filled with alcohol prep pads and a sticker reminding providers to regularly disinfect Stethoscopes were installed outside of patient rooms. Healthcare providers’ Stethoscope disinfection behaviors were directly observed before and after the intervention. Multivariable logistic regression models were created to identify independent predictors of Stethoscope disinfection.Results. Two hundred twenty-six observations were made in the preintervention...

predictors of Stethoscope disinfection among pediatric health care providers
American Journal of Infection Control, 2012Co-Authors: Jeanette Muniz, Justin Zaghi, Rosh K V Sethi, Sonja Ziniel, Thomas J. SandoraAbstract:Background: Stethoscopes are contaminated with bacteria, but predictors of Stethoscope disinfection frequency are unknown. We sought to describe health care provider Stethoscope disinfection attitudes and practices and determine predictors of frequent disinfection. Methods: We used an anonymous online survey of nurses, nurse practitioners, and physicians at a pediatric hospital. We assessed frequency and methods of disinfection, perceptions of contamination, and barriers to disinfection. Multivariate logistic regression models were used to identify independent predictors of disinfecting after every use. Results: One thousand four hundred one respondents completed the survey: 76% believed that infection transmission occurs via Stethoscopes, but only 24% reported disinfecting after every use. In multivariate analyses, belief that infection transmission occurs via Stethoscopes significantly increased the odds of disinfection after every use (odds ratio [OR], 2.06 [95% confidence interval (CI): 1.38-3.06]). The odds of disinfection after every use were significantly decreased in those who perceived the following barriers: lack of time (OR, 0.31 [95% CI: 0.18-0.54]), lack of access to disinfection material (OR, 0.41 [95% CI: 0.290.57]), or lack of visual reminders to disinfect (OR, 0.22 [95% CI: 0.14-0.34]). Conclusion: Only a minority of pediatric health care providers reported disinfecting their Stethoscopes after every use. Increasing access to disinfection materials and visual reminders in health care facilities may improve Stethoscope disinfection practices.
