nfection risks from sterile processing errors has once more
made the list in ECRI Institute’s 2020 list of Top 10 Health
Technology Hazards. As the report explains, “Insufficient
attention to sterilization processes in medical offices, dental
offices, and some other ambulatory-care settings can expose
patients to contaminated instruments, implants, or other
critical items.”
Coming in at No. 3 on the hazards list, the report adds,
“…failure to consistently and effectively clean and disinfect or
sterilize contaminated items before use can expose patients
to virulent pathogens.
This concern exists in all healthcare settings where patients
may come in contact with contaminated items, particularly
those intended to enter sterile tissue or the vascular system.
However, not all healthcare settings have similar resources for
core infection prevention and control (IPC) practices. Settings
that may lack the sterilization program resources commonly
found in acute-care facilities, for example, include medical
offices (e.g., OB/GYN, dermatology), dental offices, and similar
locations that are not serviced by a central sterile processing
department. During IPC consultations in these settings, ECRI
has observed numerous oversights and improper actions
associated with sterilization processes. While the prevalence
of such failures is unknown, the potential exists for this to
be an insidious, widespread patient safety risk.”
ECRI Institute emphasizes that key safety measures include
“designating a qualified staff member or contractor to support
office IPC practices and providing appropriate training for,
and conducting periodic competency testing of, benchtop
sterilizer operators.”
A 2018 survey of the IAHCSMM membership by epi-
demiologist Cori Ofstead, MSPH and her team, found that
many sterile processing technicians continued to struggle
with adherence to guidelines and recommended practices.
And as Ofstead, Hopkins and Buro, et al. (2020) note,
“Endoscope reprocessing is often ineffective, and microbes
frequently remain on endoscopes after the use of high-level
disinfectants (HLDs). Several factors impact reprocessing
effectiveness, including non-adherence to guidelines, use
of damaged endoscopes, use of insoluble products during

• Clinical use of endoscopes with visible damage
• Use of products that may interfere with reprocessing
such as simethicone lubricants and tissue glue
• Presence of residual soil after manual cleaning
• Rinse-water quality issues
• Retained moisture in fully reprocessed endoscopes
“In this context, reprocessing failures would not be
unexpected,” the researchers say. “However, reprocessing
failures have also been documented when no breaches
were apparent.”
Ofstead and her team suspected that issues with HLD
chemistries and monitoring could also contribute to repro-
cessing failures. Ofstead, Hopkins and Buro, et al. (2020)
conducted a mixed-methods analysis of published literature,
their interviews with frontline personnel, and evidence from
their previous studies.
They report, “The evidence showed that reusable HLDs
commonly failed tests for minimum effective concentration
(MEC) before their maximum usage periods. MEC tests also
detected failures associated with single-use HLDs that did
not fully deploy. These failures were due to product issues,
process complexities, and personnel non-adherence with
guidelines and manufacturer instructions.”
Ofstead, Hopkins and Buro, et al. (2020) say they have
observed widespread non-adherence to minimum standards
for high-level disinfection use and MEC testing at many
sites and note, “One common barrier described by Frontline
staff was reprocessing instruction for use complexity. Most
IAHCSMM survey respondents had read IFUs for flexible
endoscopes, but one-third of them reported that the IFUs
were not understandable or feasible.”
They add, “Concerns about IFU complexity are amplified
by in insufficient training. Most survey respondents received
a week or less of training before beginning to reprocess
endoscopes independently. Only 46 percent received
model specific training that covered unique steps required for
reprocessing each type of endoscope used in their facilities.
Multiple types of AERs were in use at 17 percent of facilities,
and the use of multiple systems increase the number of IFUs
that technicians must understand and remember. This also
raises the possibility of using the wrong combination of HLD
chemistries and MEC testing materials.”
The researchers continue, “Most survey respondents (70
percent) reported feeling pressure to reprocess endoscopes
more quickly, and 26 percent reported one of their biggest
challenges was not having enough time for reprocessing.
Our studies have found a proper endoscope reprocessing
requires well over one hour per endoscope yet frontline staff
reported being expected to turn endoscopes around much
more rapidly. In addition, 17 percent of survey respondents
reported skipping steps or doing them were quickly then
they should do to time pressure. Two interviewees reported
that manufacturer sales representatives had recommended
