Patient Safety, FDA Requirements and an Effective Recall Process
By Edwin Ross, BS, MS
half of the last decade (1995-2000), awareness has been heightened concerning
patient safety. Organizations such as Health Care Financing Administration (HCFA)
and the Joint Commission on Accreditation of Healthcare Organizations (JCAHO)
have added regulatory requirements and accreditation standards to protect
Recently another regulatory body, the FDA (Federal Drug Administration),
announced that it would be conducting research concerning hospital practices
related to the reprocessing of single-use devices (SUDs). The main objective is
to gather data about Class III Medical Devices that pose the highest potential
risk for patients.1
On their Reuse Web Site (www.fda.gov/reuse),
the FDA states:
- One of the goals of the FDA is to protect the health of the public by
assuring that the practice of reprocessing and reusing single-use devices (SUDs)
is safe and effective and based on good science.
- The FDA has designed an approach that applies existing regulations for
original equipment manufacturers (OEMs) to third parties and hospitals to
minimize risks associated with reprocessed SUDs.
- The public expects and the law requires all medical devices to be safe,
effective, and manufactured in accordance with Good Manufacturing Practices
(GMPs) now referred to as Quality System Regulations (QSRs).
- Based upon an assessment of potential risk, the FDA plans to phase-in
additional oversight to ensure those organizations that manufacturer or
re-manufacture medical devices, to include SUDs, are in compliance with the
JCAHO announced that the FDA selected them as the organization that will, for
the next six months, collect, aggregate and report the aggregated data about the
current practices of healthcare organizations concerning the reuse of SUDs.2
With that being the current state of affairs, it does not take much effort to
determine what the future may hold for healthcare organizations that not only
reprocess and reuse SUDs, but also process any items that may put a patient at
Healthcare organizations may be required to have a manufacturing process that
will mirror or replicate the requirements of QSRs used by medical device
manufacturers for not only SUDs but also all processed items. This process will
require standardized/validated cleaning and decontamination procedures,
packaging criteria, labeling of items, loading of sterilizers, sterilization
processes (i.e., equipment, sterilant quality, and quantity), controlled
quarantine, transportation, storage sites, documentation of the above, and a
method of recall if the manufacturing system fails.
Results learned from a study conducted in 1997, and subsequently published in
Surgical Services Management in 1998, indicated that the best way to
prevent a recall situation is effective quarantine and biological monitoring.
The study showed that as the frequency of biological monitoring increased, the
- Patient safety increased through the potential reduction of
- Costs were reduced by controlling the risk of liability and minimizing the
number of items that were to be recalled. Limiting the subsequent
reprocessing associated with multiple load recalls further reduced cost.
- Most difficult to objectively determine is the loss of confidence in the
sterile processing system that is proportionate to the size of the recall
conducted within the organization.
The conclusion of that study demonstrated that it was clinically and
operationally more effective to monitor every load with a biological indicator,
which requires as little as a one to three-hour quarantine period, than to
monitor daily or weekly.3 This is because the cost of every load
monitoring with a rapid readout biological indicator and short term quarantining
is less expensive than the costs associated with recall, healthcare-acquired
infections and litigation.
However, monitoring is only one component of the complex scientific
sterilization process. Each component of that process should be able to pass
several challenges to its validity both as a stand-alone sub process and as a
component of a larger system. In the future, the FDA may require the use of
legally binding protocols or that the organization has a process that has
demonstrated it is scientifically and operationally sound. While it is
preferable for a healthcare organization to have its sterilization processing
system working according to design, this does not always happen. Of all the
sterile processing subsystems, the final safeguard and last chance to prevent
patient harm is to have an effective recall system.
The FDA has specific guidelines for recalls:
- Recall is required if a product may cause serious adverse health
consequences or death [FDA, Title 21, Part 7, Section 3 (m)(1)].
- Recall is required if a product may cause temporary or medically
reversible adverse health consequences or where the probability of serious
adverse health consequences is remote [FDA, Title 21, Part 7, Section 3
- Recall is required if a product associated with a situation in which use
of or exposure to a product is not likely to cause adverse health
consequences [FDA, Title 21, Part 7, Section 3 (m)(3)].
For medical device manufacturers, the reasons for recall are very broad.
Product maybe recalled because of questionable sterility but also because the
product performance may affect the safe and efficacious use of the product.
Because a medical device manufacturer uses a validated process and items are not
released until all the testing indicates that the sterilization process was
effective, a recall due to ineffective sterilization is rare in the medical
device industry. In healthcare organizations, a recall is usually the result of
concern over the sterility of the medical device.
When and how to recall medical devices processed in a healthcare facility is
defined by the recommended practices published by the Association for the
Advancement of Medical Instrumentation (AAMI).4-7
These recommended practices clearly state that a healthcare facility must
have written policies and procedures for the recall of supplies sterilized by
the healthcare facility that are issued or stored. These policies should be in
compliance with the Safe Medical Devices Act of 1900.9 This act
requires that a healthcare facility establish a recall procedure to quickly
retrieve processed medical devices that are suspected to be non-sterile and to
ensure adequate follow-up with physicians and patients. These policies and
procedures must be developed in cooperation with the infection control committee
and risk management.
The recommended practices state that a healthcare organization should recall
all medical devices processed in a sterilizer when there is a positive
biological indicator or any monitoring controls such as the mechanical monitors,
internal or external chemical indicators suggest that the load was not properly
run or was questionable. In the case of a positive biological indicator (BI),
all loads processed in the sterilizer in question should be recalled since the
last negative biological indicator was obtained.4-8 Recall steps are
listed in Table 1.10
Most healthcare organizations do not have the time, money, space or human
resources required to document such high standards as required by QSRs. In fact,
most organizations do not have processes that would minimally meet QSRs.
Therefore an effective recall system is needed. Additionally, it is only because
the FDA, to this point in time, has not regulated hospital sterile processing
systems that healthcare organizations have been allowed to claim that they are
able to manufacture to the same level of patient safety assurance as medical
device manufacturers without proving it. This should be coming to a stop.

Solutions to Sterilization Problems
By Phillip Davis
long and continuing problem encountered with steam and/or ethylene oxide
sterilization is the presence of moisture associated with instrument and basin
sets, which is commonly known as "wet packs." There are numerous
factors that can contribute to this problem, such as:
- Excessive weight in instrument trays or basins
- Boiler or plumbing changes
- New or different sterilizers
- Staff changes and/or new personnel
- New medical devices
- Changes in seasons
- New rigid containers or wrap material
As indicated in the ANSI/AAMI ST46-1993: Good Hospital Practice: Steam
Sterilization and Sterility Assurance, page 13 (1994), a towel or other
absorbent material may be placed in the tray or between nested basins to
facilitate drying. A new highly absorbent, lint-free foam Instrument Tray Liner
and Basin Divider manufactured by General Hospital Supply Corporation in Wilton,
Conn., is now available. This product can be used in a Closed Container System
as well as an open Sterilizing Tray.
In conclusion, there is no easy solution to the continuing "wet
pack" problem that exists during the sterilization process at present;
however, identifying the causes and improving techniques is a step in the right
Gas Plasma Sterilization
There are generally three sterilization processes for use on surgical
equipment: High-temperature steam, ethylene oxide, and low temperature
hydrogen-peroxide gas plasma. For a number of reasons, hydrogen-peroxide gas
plasma sterilization is becoming a preferred sterilization method by many
technicians. For example, hydrogen-peroxide gas plasma sterilization has
significantly less corrosive effect on metal surgical instruments and leaves no
residue that may cause the sterilized surgical instruments to be irritating or
toxic to patients.
In addition, hydrogen-peroxide gas plasma sterilization produces no toxic
by-products and requires no special ventilation or aeration.
A STERRAD® hydrogen-peroxide gas plasma sterilization system
available from Advanced Sterilization Products of Irvine, Calif., for example,
is designed to provide non-toxic, dry, low temperature sterilization in about
one hour without toxic residues. However, the STERRAD system (at left) is not
usable with cellulose-based products like linen or paper normally used in other
A tray liner is then needed to cushion articles such as fiber optic
endoscopes, laser handpieces, power drills, and ophthalmic devices as they are
placed in a hydrogen-peroxide gas plasma sterilization system. Preferably, the
trayliner should have low absorbency, yet will allow the passage of plasma
therethrough such that an article can be effectively sterilized in the system.
General Hospital Supply Corporation manufactures a lint free foam Instrument
Tray Liner, available to hospitals and surgicenters. This product is the only
disposable tray liner that is "Sterrad" compatible and will sterilize
lumen devices as well.
