Cleaning, Sterilization, & High Level Disinfection (HLD)

Objectives

At the conclusion of this presentation, participants will be able to:

• Explain the difference between cleaning, disinfection,

and sterilization

• Match the Spaulding Classification for Medical Devices

with the required level of disinfection for medical equipment

• Translate the process of cleaning, sterilization, and high

level disinfection in your own setting

• Develop an instrument Recall Procedure
• Develop a cleaning, sterilization and high level

disinfection competency

Background

• 2014 - Formal education completed
• 2015 - Leadership and Infection Prevention audits

identified inconsistent practices

• Several new sites acquired since 2014 education
• Several cleaning and sterilization products not on

contract with the health system

• Physician practice sites primarily staffed by medical

assistance (MA) who are expected to perform sterile processing duties amongst their other duties

– Variability in sterile processing education – High turn over

• 9/11/15: CDC/FDA Health Advisory Issued

– Immediate Need for Healthcare Facilities to Review Procedures for Cleaning, Disinfecting, and Sterilizing Reusable Medical Devices

11/7/2016 3

How did we start?

• Identified the following:

– Outpatient sites that have sterilizers – Types of sterilizers – Products being used for cleaning, high level disinfection, and sterilization – Procedures being performed – Instruments being used – Instructions For Use (IFU) of instruments, products, and autoclave

• Completed education needs assessment
• Standardized, educated, and audited our

process

What is the difference between cleaning, disinfection, and sterilization?

• Cleaning

– General removal of debris (dirt, food, feces, blood, saliva and

• ther body secretions)

– Reduces amount of organic matter that contributes to proliferation of bacteria and viruses

• Disinfection

– Removes most organisms present on surfaces that can cause infection or disease

• Low Level Disinfection (LLD) – kills some viruses and bacteria
• Intermediate Level Disinfection (ILD) – kills mycobacteria, most

viruses, and bacteria

• High Level Disinfection (HLD) – kills all organisms, except high

levels of bacterial spores

• Sterilization

– The killing or removal of all organisms, including bacteria, viruses, spores, and fungi

Spaulding Classification for Medical Devices and Levels of Disinfection

• Noncritical Items:

Devices that do not ordinarily touch the patient or touch only intact

• skin. These devices should be cleaned by low-level disinfection.
• Semi critical Items:

A device that comes into contact with intact mucous membranes and does not ordinarily penetrate sterile tissue. These devices should receive at least high-level disinfection.

• Critical Items:

A device that enters normally sterile tissue, the vascular system, or through which blood flows. Such devices should be sterilized.

11/7/2016 4

Patient Contact Device Classification Examples Recommended Level of Processing

• Low Level Disinfection

(LLD)

• High Level Disinfection

(HLD)

• Sterilization

Intact Skin Noncritical Items LLD Mucous membranes or non-intact skin Semi critical Items

• At a minimum

HLD

• Sterilization

Cleaning, Disinfecting and Sterilizing… Easy Process??

Cleaning of Instruments

11/7/2016 5

Clean vs. Soiled Utility Rooms

• Current State: All practice sites are space

constrained

– Many sites are performing cleaning of soiled instruments in the same room with sterilization and high level disinfection – Physician practice buildings were not built with infection prevention in mind

• Ideal State: Each practice site has a separate

clean and soiled utility room

– Sterilization and HLD should take place in a clean room

IF IT IS NOT CLEAN IT CAN NOT BE STERILE

Transporting Soiled Instruments

“Approved container – a rigid container with a cover will be used if dirty instruments

• r equipment need to be transported to a

soiled utility area for cleaning and sterilization”

11/7/2016 6 Instrument Transport Spray

• Surfactant-based gel with corrosion inhibitors

which allows instruments to stay moist so blood and body fluid don’t dry on

• Spray on instruments at point of use prior to

transferring to the soiled utility room

Enzymatic Detergent

• A detergent that removes soil and debris from

instruments prior to sterilization.

• Dual protease enzyme that attacks blood and fat
• Excellent cleaning properties
• Safe for surgical and endoscopic instruments
• Follow manufacturer guidelines for:

– Dilution – Soaking time

Enzymatic Detergent PPE

• Use PPE including fluid resistant gown, gloves,

face shield or facemask with eye shield every time you use this product.

– Enzymatic detergents can cause skin irritation and eye damage if they come in contact with your skin or eyes

11/7/2016 7

Brushes

• Scrub instruments, as needed, below

surface of enzymatic solution using a non-metal scrub brush

• Brushes shall be changed when brush

bristles are frayed

• Follow manufacturer guidelines related to

cleaning of brushes

• Brushes should be available for all

instruments including lumen instruments

Instrument Lubrication

• Instrument lubrication is used to:

– Prevent rusting – Keep surgical instruments operating freely and easily

• Follow lubricant manufacturer guidelines

Instrument Cleaning Process

• Don PPE
• Place instruments in the enzymatic solution.

– *Important* - Instruments must be in the open unlocked position while soaking – Take apart instruments that come apart for effective cleaning

• Scrub instruments, as needed, below the surface of

enzymatic solution using a non-metal scrub brush

• Soak instruments in the enzymatic solution per

manufacturer recommendations

• Rinse instruments in warm tap water

– Be aware of possible sharp objects in soaking solution – remove instruments with caution – Inspect instrument to be sure that all debris and blood or body fluids are removed

• Dip hinged instruments in lubrication solution
• Allow instruments to air dry

*Important* - Instruments must be completely dry before you can package and place in sterilizer.

Instrument Inspection

Instrument Inspection

• Instrument inspection is a key step in safety
• Instruments will wear over time and if not

inspected on a regular basis can cause harm to patients and/or frustration for your provider

• Key things to look for when inspecting your

instruments are:

– Stains, rust, dried on blood or tissue debris – Cracks, wear, missing pieces, finish damage

The larger the crack the longer it has been there Plating/metal finish can chip off

Paper Test determines unstable finish - Rub with gloved hands

11/7/2016 9

Instrument Inspection Example Instrument Teeth Inspection

This is what they should look like

Examples of Damaged Teeth

11/7/2016 10

How to inspect an instrument

• Inspect instrument for cleanliness:

– If blood or debris still present, re-wash in enzymatic detergent utilizing scrub brush

• Inspect instrument for damage and sharpness:

– Remove from service any instruments with any defects – Place appropriate tag on instrument:

• Red Tag = Repair of Instrument
• Yellow Tag = Sharpening of Instrument

– Schedule appointment with instrument repair company

• Inspect instrument for wetness:

– Visually inspect instrument for any signs of wetness – If wet, allow instrument to dry longer

Instrument Pouching

Pouching 101

Do not fold over to fit item Improper gap The fold line is in the wrong place Always fold at the perforation with no gaps

11/7/2016 11

Packaging Instruments in Pouches

• Place sharp instrument tips in approved tip

protectors

• Place dry clean instruments, handles in first, in a

pouch appropriate to the size of the instrument

• Instruments are to be in the open unlocked position
• Place a chemical indicator in pouch

Packaging Instruments in Wrapping

• Use only one step wrap in appropriate size - Do not cut

the wrap

• Heavier instruments are placed in the tray first
• Curved tips are always positioned in the same direction
• Cupped or concaved instruments are positioned to avoid

water/condensation collection

• Place a chemical indicator in tray and optional outside of

tray

• Secure wrap with a maximum of 3 strips steam indicator

tape

Labeling – Our Process

• Label the outside of wrapped packages and the

lower right hand corner plastic side of pouches with an alcohol based marker (e.g. Scripto or Sharpie) if label gun not available.

• Include the following:

– Date sterilized – Load number – Initials of person performing the sterilization process – Department if it is a shared autoclave – Sterilizer name or number, if more than one sterilizer at the site

11/7/2016 12

Autoclaves

Methods of Sterilization

• Steam Flush Pressure Pulse - a repeated sequence consisting of

a steam flush and a pressure pulse system that removes air from the sterilizing chamber and processed materials using steam at above atmospheric pressure (no vacuum is required).

– No approved biological indicator for Ritter MidMark

Methods of Sterilization

• Gravity - steam is pumped into a chamber containing ambient air.

Because steam has a lower density than air, it rises to the top of the chamber and eventually displaces all the air. As steam fills the chamber, the air is forced out through a drain vent. By pushing the air out, the steam is able to directly contact the load and begin to sterilize it

Amsco

11/7/2016 13

Methods of Sterilization

• Pre-Vacuum - a series of alternating steam pressure injections and

vacuum draws (also called pulses) to dynamically remove the air from the chamber

Gettinge Steris

Loading a Sterilizer

• Pouches:

– Standing on edge with paper side of one pouch next to plastic side of the other – must be able to put your hand between pouches

• This cannot be done unless you have the correct tray

– Lying flat with paper side down

• Single layer, may overlap but not stack on each other
• Wrapped Packs:

– Solid tray: Loosely loaded and positioned on edge so that all fabric layers are perpendicular to the shelf – Perforated or Mesh tray: Load with tray bottom down

Sterilization Quality Controls

11/7/2016 14

Monitoring Sterilization

• Mechanical Indicators

– Not indicator of sterility – Gauges, displays, printouts – Indicates if device working properly

• Chemical Indicators

– Not indicator of sterility – Change color with timed exposure to heat, steam – Used to show items have gone through sterilization process – Class 1 thru 5

• Biological Indicators

– Indicator of sterility – Demonstrates bacterial spores on test strips or in vials/containers have all been killed

Chemical Indicator/Integrator (CI)

• EVERY pouch and tray EVERY time
• Ensure that a CI is placed where it is visible

in each pouch

• Confirm that the strip change passes when

removing pouch from the autoclave

Tier Site Recommended Time for BI Tier 1 Ambulatory Surgery Center (ASC)

• Treat like a hospital
• perating room
• 1 hour BI

Tier 2 High Volume Sites

• Sites that use the

sterilizer daily

• 3 hour BI daily
• Tuttnauer only – 1 hour

BI daily Tier 3 Low Volume Sites

• Sites that use the

sterilizer 1-4 times/week

• r less

(CDC and AAMI minimum standard)

Biological Indicators (BI) AMG Tiered Risk Assessment

11/7/2016 15

AMG Biological Indicator QC

• Select 2 BI ampules with the same lot number
• Label BI ampules as follows:

– BI ampule #1 – “P”, date, load #, autoclave #, initials – BI ampule #2 – “C”, date, initials

• Crush the control “C” BI ampule and incubate
• Create a challenge pack

– Pouch: “P” ampule and chemical integrator/indicator – Wrapped pack: old instruments, “P” ampule, and chemical integrator/indicator

• Place challenge pack in the most difficult area inside the

sterilizer (i.e. next to the drain, in the center of multiple pouch/pack load)

– Place other pouches that need to be sterilized in your BI test load but they cannot be released for use until your biological testing has passed.

• Run load
• Remove challenge pack.

– Allow to cool for 10 min

AMG Biological Indicator QC

• Crush the processed (P) BI ampule and incubate

– Let BI ampule incubate for the specified amount of time according to your tier level.

• Read BI Results

– Tier 2: Read auto reader display screen

• Processed (P) ampule should display a negative (-) sign.
• Control (C) ampule should display a positive (+) sign indicating spores are

detected

– Tier 3: Observe BI ampule for color change

Processed (P) ampule should remain purple and clear Control (C) ampule should turn yellow and cloudy

Failed Biological Indicators

• Repeat BI test in the next load

– Failure could be due to human error

• If repeat BI passes, the sterilizer can continue

to be used

• If repeat BI fails, follow the “AMG Recall of

Sterilized Items due to Positive Biological Indicator” Procedure

11/7/2016 16

AMG Recall of Sterilized Items due to Biological Indicator Failure

• Notify your immediate supervisor
• Identify and remove from stock, all items that have been

sterilized since last negative BI

• Record the positive BI result in the logbook in “Red” ink
• Remove sterilizer from service, apply red tag for

nonconforming products, and contact ACE.

• Report incident per protocol
• Notify providers in office,

Infection Prevention, Quality, and Risk Management

AMG Recall of Sterilized Items due to Biological Indicator Failure

• Record on the Sterilization Instrument Recall Log the

items retrieved, items not retrieved in the recall, and actions taken on recalled items

AMG Recall of Sterilized Items due to Biological Indicator Failure

• If recalled items have been used, identify what patient(s)

the items were used on. Complete the Instrument Recall – Patient Log and send to infection prevention

11/7/2016 17

Additional BI Testing

• 3 consecutive cycles should be run, 1 right

after the other with a challenge pack when the following occurs:
