§482.41(d)(2) - Facilities, supplies, and equipment must be maintained to ensure an
acceptable level of safety and quality.
Interpretive Guidelines §482.41(d)(2)
Facilities
The hospital must ensure that the condition of the physical plant and overall hospital
environment is developed and maintained in a manner that provides an acceptable level of safety
and well-being of patients, staff and visitors.
Supplies
The hospital must ensure that supplies are maintained to provide an acceptable level of safety
and quality for patients. Among other things, this means that the hospital identifies the supplies
required to meet its patients’ needs for both day-to-day operations as well as those supplies that
are likely to be needed in likely emergency situations, such as mass casualty events resulting
from natural disasters, mass trauma, disease outbreaks, etc. Further, the hospital must make
adequate provisions to ensure the availability of those supplies when needed.
Supplies must be stored in such a manner to ensure their safety (e.g., protection against theft or
damage, contamination, or deterioration), as well as that the storage practices do not violate fire
codes or otherwise endanger patients (e.g., storage of flammables, blocking passageways,
storage of contaminated or dangerous materials, safe storage practices for poisons, etc.).
Equipment
In order to ensure an acceptable level of safety and quality, the hospital must identify the
equipment required to meet its patients’ needs for both day-to-day operations and in a likely
emergency/disaster situation, such as mass casualty events resulting from natural disasters,
mass trauma, disease outbreaks, internal disasters, etc. In addition, the hospital must make
adequate provisions to ensure the availability and reliability of equipment needed for its
operations and services. Equipment includes both facility equipment, which supports the
physical environment of the hospital (e.g., elevators, generators, air handlers, medical gas
systems, air compressors and vacuum systems, etc.) and medical equipment, which are devices
intended to be used for diagnostic, therapeutic or monitoring care provided to a patient by the
hospital (e.g., IV infusion equipment, ventilators, laboratory equipment, surgical devices, etc.).
All equipment should be inspected and tested for performance and safety before initial use and
after major repairs or upgrades.
All equipment must be inspected, tested, and maintained to ensure its safety, availability, and
reliability. Equipment maintenance activities may be conducted using hospital personnel,
contracted services, or through a combination of hospital personnel and contracted services.
Individual(s) responsible for overseeing the development, implementation, and management of
equipment maintenance programs and activities must be qualified. The hospital should maintain
records of hospital personnel qualifications and be able to demonstrate how it ensures all
personnel, including contracted personnel, are qualified.
All equipment maintenance policies, procedures, and programs, as well as specific equipment
maintenance inventories, activities, and schedules, fall under the purview of the hospital’s
clinical maintenance personnel, safety department personnel or other personnel who have been
assigned responsibility for equipment maintenance by hospital leadership.
As mentioned in S&C memo 14-7 regarding equipment maintenance, hospitals comply with this
regulation when they follow the manufacturer-recommended maintenance activities and
schedule. Hospitals may choose to perform maintenance more frequently than the manufacturer
recommends, but should use the manufacturer-recommended maintenance activities in such
cases. When equipment is maintained in accordance with the manufacturer’s recommendations,
the hospital must maintain documentation of those recommendations and the hospital’s
associated maintenance activity for the affected equipment.
Alternate Equipment Management (AEM) Program
A hospital may, under certain conditions, use equipment maintenance activities and frequencies
that differ from those recommended by the manufacturer. Hospitals that choose to employ
alternate maintenance activities and/or schedules should develop, implement, and maintain a
documented AEM program to minimize risks to patients and others in the hospital associated
with the use of facility or medical equipment. An AEM program must be based on generally
accepted standards of practice for facility or medical equipment maintenance. An example of
guidelines for a medical equipment medical equipment maintenance program may be found in
the American National Standards Institute/ Association for the Advancement of Medical
Instrumentation document: ANSI/AAMI EQ 56:2024, Recommended Practice for a Medical
Equipment Management Program. Likewise, an example of guidelines for physical plant
equipment may be found in the American Society for Healthcare Engineering (ASHE) 2014
document: Maintenance Management for Health Care Facilities. There may be similar
documents issued by other nationally recognized organizations which hospitals might choose to
reference.
Decision to Place Equipment in an AEM Program
The determination of whether it is safe to perform facility or medical equipment maintenance
without following the equipment manufacturer recommendations should be made by qualified
personnel, regardless of whether they are hospital employees or contractors.
In the case of medical equipment, a clinical or biomedical technician or engineer would be
considered qualified. Highly specialized or complex equipment may require specialized
knowledge or training in order for personnel to be considered qualified to make a decision to
place such equipment in an AEM program.
In the case of facility equipment, a Healthcare Facility Management professional (facility
manager, director of facilities, vice president of facilities) would be considered qualified.
The hospital must maintain records of the qualifications of hospital personnel who make
decisions on placing equipment in an AEM program and must be able to demonstrate how they
assure contracted personnel making such decisions are qualified.
In determining whether or not to include equipment in an AEM program, and which
maintenance strategies to use in developing maintenance activities and frequencies for
particular equipment, the hospital takes into account the typical health and safety risks
associated with the equipment’s use. Note that the risk may vary for the same type of equipment,
depending on the patient care setting within the hospital where it is used.
A hospital should identify any equipment in its AEM program which is “critical equipment,” i.e.,
biomedical or physical plant equipment for which there is a risk of serious injury or death to a
patient or staff person should the equipment fail. Surveyors must focus their review of a
hospital’s AEM program on critical equipment and the hospital’s documentation of the factors
and evidence it considered in developing an AEM strategy for that equipment.
Factors for a hospital to consider when evaluating the risks associated with a particular type of
equipment may include, but are not limited to:
• How the equipment is used and the likely consequences of equipment failure or malfunction -
would failure or malfunction of the equipment hospital-wide or in a particular setting be
likely to cause harm to a patient or a staff person?
• How serious is the harm likely to be? For example, a slightly miscalibrated scale in
an adult internal medicine outpatient clinic might not present significant risk of harm.
However, a miscalibrated scale in a neonatal intensive care unit could have very
serious consequences for patient care.
o How widespread is the harm likely to be? For example, are many patients exposed to
the equipment, resulting in harm due to failure impacting more patients or staff? If
harm would be widespread, even if the harm to each affected individual is not
serious, this would be a cause for concern.
• Information, if available, on the manufacturer’s equipment maintenance recommendations,
including the rationale for the manufacturer’s recommendations;
• Maintenance requirements of the equipment:
• Are they simple or complex?
• Are the manufacturer’s instructions and procedures available in the hospital, and if
so can the hospital explain how and why it is modifying the manufacturer’s
instructions?
• If the manufacturer’s instructions are not available in the hospital, how does the
hospital assess whether the AEM uses appropriate maintenance strategies?
• How readily can the hospital validate the effectiveness of AEM methods for particular
equipment? For example, can the hospital explain how it ensures there is no
reduction in the quality of the performance of biomedical equipment subjected to
alternate maintenance methods?
• The timely availability of alternate devices or backup systems in the event of equipment
failure or malfunction; and
• Incident history of identical or very similar equipment – is there documented evidence, based
on the experience of the hospital (or its third party contractor), or on evidence publicly
reported by credible sources outside the hospital, which:
• Provides the number, frequency and nature of previous failures and service requests?
• Indicates use of an AEM strategy does not result in degraded performance of the
equipment?
Generally multiple factors are considered since different types of equipment present different
combinations of severity of potential harm and likelihood of failure. The hospital should be able
to demonstrate to a surveyor the factors it considered in its risk assessment for equipment placed
in its AEM program.
Equipment not Eligible for Placement in the AEM Program:
Some equipment may not be eligible for placement in the AEM program, for one or more of the
following reasons:
• Other Federal law (for example, regulations promulgated by another Federal agency) or
State law may require that facility or medical equipment maintenance, inspection and testing
be performed strictly in accordance with the manufacturer’s recommendations, or may
establish other, more stringent maintenance requirements. In these instances, the hospital
must comply with these other Federal or State requirements, but State surveyors conducting
Federal surveys assess compliance only with the hospital Conditions of Participation (CoPs).
• Other CoPs require adherence to manufacturer’s recommendations and/or set specific
standards which preclude their inclusion in an AEM program. For example:
• The National Fire Protection Association LSC requirements incorporated by
reference at 42 CFR 482.41(b) has some provisions that are pertinent to equipment
maintenance, and compliance with these requirements are assessed on Federal
surveys. Further, §482.41(b)(7) requires that hospitals may install ABHRs if they are
installed in a manner that adequately protects against inappropriate access.
Hospitals should be following the manufacturer’s maintenance guidelines when using
ABHRs. Compliance with these requirements is assessed on Federal surveys.
• Imaging/radiologic equipment, whether used for diagnostic or therapeutic purposes,
is governed by 42 CFR 482.26(b)(2) and must be maintained per manufacturer’s
recommendations.
• The equipment is a medical laser device. It should be noted that for medical lasers the U.S.
Food and Drug Administration requires manufacturers to provide a schedule of maintenance
and adequate instructions for service adjustments and service procedures to purchasers and,
at cost, to any other parties requesting them.
• New equipment for which sufficient maintenance history, either based on the hospital’s own
or its contractor’s records, or available publicly from nationally recognized sources, is not
available to support a risk-based determination should not be immediately included in the
AEM program. New equipment should be maintained in accordance with manufacturer
recommendations until a sufficient amount of maintenance history has been acquired to
determine whether the alteration of maintenance activities or frequencies would be safe. If a
hospital later transitions the equipment to a risk-based maintenance regimen different than
the manufacturers’ recommendations, the hospital should maintain evidence that it has first
evaluated the maintenance track record, risks, and tested the alternate regimen.
Alternative Maintenance Frequencies or Activities
Maintenance strategies are various methodologies used for determining the most efficient and
effective maintenance activities and frequencies. Manufacturers’ recommendations may be
based on one or more such strategies. A hospital may also use one or more maintenance
strategies for its AEM program in order to determine the appropriate maintenance, inspection,
and testing activities and frequencies, based upon the nature of the equipment and the level of
risk it presents to patient or staff health and safety. The risk to patient health and safety that is
considered in developing alternative maintenance strategies must be explained and documented
in the AEM program.
In developing AEM maintenance strategies hospitals may rely upon information from a variety
of sources, including, but not limited to: manufacturer recommendations and other materials,
nationally recognized expert associations, and/or the hospital’s (or its third party contractor’s)
own experience. Maintenance strategies may be applied to groups or to individual pieces of
equipment.
The hospital is expected to adhere strictly to the AEM activities or strategies it has developed.
Background Information on Types of Maintenance Strategies
• Preventive Maintenance (Time-based Maintenance) – a maintenance strategy where
maintenance activities are performed at scheduled time intervals to minimize equipment
degradation and reduce instances where there is a loss of performance. Most preventive
maintenance is “interval-based maintenance” performed at fixed time intervals (e.g., annual
or semi-annual), but may also be “metered maintenance” performed according to metered
usage of the equipment (e.g., hours of operation). In either case, the primary focus of
preventive maintenance is reliability, not optimization of cost-effectiveness. Maintenance is
performed systematically, regardless of whether or not it is needed at the time. Example:
Replacing a battery every year, after a set number of uses or after running for a set number
of hours, regardless.
• Predictive Maintenance (Condition-based Maintenance) – a maintenance strategy that
involves periodic or continuous equipment condition monitoring to detect the onset of
equipment degradation. This information is used to predict future maintenance requirements
and to schedule maintenance at a time just before equipment experiences a loss of
performance. Example: Replacing a battery one year after the manufacturer’s recommended
replacement interval, based on historical monitoring that has determined the battery
capacity does not tend to fall below the required performance threshold before this extended
time.
• Reactive Maintenance (Corrective, Breakdown or Run-to-Failure Maintenance) – a
maintenance strategy based upon a “run it until it breaks” philosophy, where maintenance
or replacement is performed only after equipment fails or experiences a problem. This
strategy may be acceptable for equipment that is disposable or low cost and presents little or
no risk to health and safety if it fails. Example: Replacing a battery after equipment failure
when the equipment has little negative health and safety consequences associated with a
failure and there is a replacement readily available in supply.
• Reliability-Centered Maintenance – a maintenance strategy that not only considers
equipment condition, but also considers other factors unique to individual pieces of
equipment, such as equipment function, consequences of equipment failure, and the
operational environment. Maintenance is performed to optimize reliability and cost
effectiveness. Example: Replacing a battery in an ambulance defibrillator more frequently
than the same model used at a nursing station, since the one in the ambulance is used more
frequently and is charged by an unstable power supply.
Maintenance Tools
Tools (e.g., hand tools, test equipment, software, etc.) necessary for performing equipment
maintenance must be available and maintained to ensure that measurements are reliable. Tools
used for maintenance are not required to be those specifically recommended by the
manufacturer, but tools utilized must be capable of providing results equivalent to those required
by the equipment manufacturer.
AEM Program Documentation
For each type of equipment subject to the AEM program, there should be documentation
indicating:
• The pertinent types and level of risks to patient or staff health and safety;
• Alternate maintenance activities, and the maintenance strategy and any other rationale
used to determine those activities; the differences from the manufacturer’s recommended
maintenance activities are made explicit, unless the hospital is unable to obtain the
manufacturer’s maintenance recommendations, due to the age of the equipment or the
manufacturer’s restricting the availability of its recommendations;
• Alternate maintenance frequencies to be used, if any, and the maintenance strategy and
any other rationale used to determine those frequencies. For equipment identified as
presenting a very low risk to patient or staff safety, it could be acceptable to not set a
particular frequency but instead indicate a less specific approach, for example, an
interval range, such as “every 12 – 24 months.” It could also be acceptable to employ
periodic “departmental sweeps” for such very low risk equipment, where equipment
functioning is sampled and operators are polled about its functionality.
• The date when AEM program maintenance activities were performed and, if applicable,
further actions required/taken; and
• Documentation of any equipment failures (not including failures due to operator error),
including whether there was resulting harm to an individual. (Note: equipment failure
that is due to operator error and which results in an adverse event or near miss must be
documented in accordance with the QAPI CoP, as part of the hospital’s required
tracking of patient safety-related incidents. However, there is no requirement to include
operator failures in equipment maintenance documentation.)
When the hospital has multiple identical equipment items, the documentation may be generic to
that type of equipment, except that documentation of maintenance activities performed must be
specific to each item of equipment.
Evaluating Safety and Effectiveness of the AEM Program
The hospital must have policies and procedures which address the effectiveness of its AEM
program. In evaluating the effectiveness of the AEM program the hospital should address
factors including, but not limited to:
• How equipment is evaluated to ensure there is no degradation of performance, particularly
for equipment where such degradation may not be readily apparent to staff using the
equipment, e.g., miscalibration.
• How incidents of equipment malfunction are investigated, including:
o whether or not the malfunction could have been prevented, and what steps will be
taken to prevent future malfunctions; and
o how a determination is made whether or not the malfunction resulted from the use of
an AEM strategy;
• The process for the removal from service of equipment determined to be unsafe or no longer
suitable for its intended application; and
• The use of performance data to determine if modifications in the AEM program procedures
are required.
Equipment Inventory
All hospital facility and medical equipment, regardless of whether it is leased or owned, and
regardless of whether it is maintained according to manufacturer recommendations or is in an
AEM program, is expected to be listed in an inventory which includes a record of maintenance
activities. For low cost/low risk equipment, such as housekeeping cleaning equipment, it is
acceptable for the inventory to indicate under one item the number of such pieces of equipment
in the hospital, e.g., “15 vacuum cleaners for cleaning patient rooms and common areas.”
If the hospital is using an AEM program, the equipment managed through that program must be
readily separately identifiable as subject to AEM. Critical equipment, whether in an AEM
program or not, must also be readily identified as such.
To facilitate effective management, a well-designed equipment inventory contains the following
information listed below for all equipment included. However, hospitals have the flexibility to
demonstrate how alternative means they use are effective in enabling them to manage their
equipment.
• A unique identification number;
• The equipment manufacturer;
• The equipment model number;
• The equipment serial number;
• A description of the equipment;
• The location of the equipment (for equipment generally kept in a fixed location);
• The identity of the department considered to “own” the equipment;
• Identification of the service provider;
• The acceptance date; and
• Any additional information the hospital believes may be useful for proper management of the
equipment.
Survey Procedures §482.41(d)(2)
Interview personnel in charge of facility, supplies and equipment maintenance:
• Determine if supplies are maintained in such a manner as to ensure an acceptable level of
safety and quality.
• Determine if supplies are stored as recommended by the manufacturer.
• Determine if supplies are stored in such a manner as not to endanger patient safety.
• Determine if the hospital has identified supplies and equipment that are likely to be needed in
emergency situation.
• Determine if the hospital has made adequate provisions to ensure the availability of those
supplies and equipment when needed.
Concerning facility and medical equipment:
• Interview equipment users when surveying the various units/departments of the hospital to
determine if equipment failures are occurring and causing problems for patient health or
safety.
• Determine if there is a complete inventory of equipment required to meet patient needs,
regardless of ownership.
o Is critical equipment readily identified?
o If the hospital employs an AEM program, is equipment in this program readily
identified?
• Determine if the hospital has documentation of the qualifications (e.g., training certificates,
certifications, degrees, etc.) of hospital personnel responsible for the AEM program (if one is
being used by the hospital) as well as for those performing maintenance.
• Determine if the hospital is able to demonstrate how it assures contractors use qualified
personnel.
If the hospital is following the manufacturer-recommended equipment maintenance activities
and frequencies:
In addition to reviewing maintenance records on equipment observed while inspecting various
hospital locations for multiple compliance assessment purposes, select a sample of equipment
from the hospital’s equipment inventory to determine whether the hospital is following the
manufacturer’s recommendations. Critical equipment which poses a higher risk to patient safety
if it were to fail, such as ventilators, defibrillators, robotic surgery devices, etc. should make up
the sample majority.
For the sample selected, determine if:
• The hospital has available manufacturer’s recommendations (e.g., manufacturer’s
operation and maintenance manual, standards, studies, guidance, recall information,
service records, etc.)
• Maintenance is being performed in accordance with manufacturer’s recommendations
If a hospital is using an AEM for some equipment:
• Does the hospital’s inventory include equipment, for example, any diagnostic imaging or
therapeutic radiologic equipment, which is not eligible for AEM?
• Determine if the hospital’s development of alternate maintenance activities and
frequencies for equipment in the AEM program as well as AEM activities are being
performed by qualified personnel.
• Verify the hospital has documented maintenance activities and frequencies for all
equipment included in the AEM program.
• Verify the hospital is evaluating the safety and effectiveness of the AEM program.
• If there is equipment on the inventory the hospital has identified as having such a very
low level of risk that it has determined it can use a broad interval range or departmental
“sweeps,” ask the hospital for the evidence used to make this determination. Does it
seem reasonable?
Select a sample of equipment in the AEM program. The majority of the sample must include
critical equipment that poses a higher risk to patient safety if it were to fail, such as ventilators,
defibrillators, robotic surgery devices, etc. For the sample selected:
• Ask the responsible personnel to explain how the decision was made to place the
equipment in an AEM program. Does the methodology used consider risk factors and
make use of available evidence?
• Ask the responsible personnel to describe the methodology for applying maintenance
strategies and determining alternative maintenance activities or frequencies for the
sampled equipment. Can they readily provide an explanation and point to sources of
information they relied upon?
• Determine if maintenance is being performed in accordance with the maintenance
activities and frequencies defined in the AEM program.
• Verify the hospital is evaluating the safety and effectiveness of the AEM maintenance
activities for this equipment and taking corrective actions when needed.
