Just In: Dr. Muscarella’s Research Discussed In the News —
- Single-Use Endoscopy: “Comprehensive Review of FDA Adverse Event Reports Involving Flexible Endoscopes Investigates Reprocessing Effectiveness” (August 23, 2022)
- Medtech Insight: “Study: FDA Data Shows Endoscope-Related Adverse Events Continue To Rise.” (Apr. 28, 2022)
- Infection Control Today: “Despite Safety Alerts, Contaminated Flexible Endoscopes Continue to Put Patients at Risk.” (Apr. 7, 2022)
- Press release: “Comprehensive Endoscope Study Reveals More Patients Are Potentially Being Exposed to Pathogens.” (Mar. 22, 2022)
Dr. Muscarella original research discussed in each of these three reports can be read here:
- “Contamination of Flexible Endoscopes and Associated Infections: A Comprehensive Review and Analysis of FDA Adverse Event Reports.”
Dr. Muscarella’s study aims to be the most comprehensive review and analysis to date of FDA adverse event reports involving a flexible endoscope, specifically device contaminations with and without associated infection.
Recent FDA alerts involving a flexible endoscope —
- April 5, 2022: “Use Duodenoscopes with Innovative Designs to Enhance Safety: FDA Safety Communication.”
- April 4, 2022: “UPDATE: Change in Reprocessing Methods with Certain Karl Storz Urological Endoscopes – Letter to Health Care Providers.”
About endoscope drying, recently published:
- Read Dr. Muscarella’s latest article: “Flushing Endoscopes With 70% Alcohol to Facilitate Channel Drying: Does this Measure Reduce the Contamination Risk?” This article provides a review of published data to clarify the contribution of a 70% alcohol rinse, prior to forced-air drying, to a reduction in the risk of endoscope contamination.
The “Transmission Control” Podcast: A newly released public health podcast co-hosted by Beyond Clean’s Justin Poulin and Lawrence F Muscarella, PhD.
- Episode 15 (Dec. 6, 2021) — “Medical Devices: Design Evolution & Variations in Standards of Care.” We discuss improvements to the design of medical devices to prevent patient infections. We focus on how our co-host — Lawrence F. Muscarella, PhD — published a unique recommendation circa 2006 about decontamination of rigid laryngoscopes that California adopted and that became the standard of care through the state. Our guest on this episode is Christian Berling of Germany’s HEINE Optotechnik, a manufacturer of reusable rigid laryngoscopes.
- This episode, and each of the other more than a dozen “Transmission Control” podcasts taped in 2021, can be heard here on Apple Podcast.

As quoted in “USA Today”:
As discussed by U.S. Congressman Ted Lieu (California’s 33rd District):
- As discussed in a letter by Mr. Lieu (March 23, 2015)
- As appears on Mr. Lieu’s webpage (June 13, 2016): “While it is unclear if the infection was a factor in the deaths — many of the patients had serious illnesses including cancer — the findings of the ongoing investigation show that, in general, the number of patients infected by dirty medical scopes is underreported, Lawrence Muscarella, a medical safety consultant in Montgomeryville, Pa., told The Los Angeles Times. ‘This shows a total failure of the system, from top to bottom,’ Muscarella told the newspaper.”
