CODE OF ETHICS OF AUDIOLOGYCODE OF ETHICS OF AUDIOLOGY

“Individuals shall exercise all reasonable precautions to avoid injury to person in the 

delivery of professional services or execution of research.”

American Academy of Audiology Part 1, Principle 2, Rule 2b

What is Infection Control?What is Infection Control?

Infection control is a process that involves the conscious management of the clinical environment for the specific purposes of minimizing the potential spread of disease. 

(Bankaitis and Kemp, 2003‐2005) 

What is the Goal of Infection Control

Reduce or eliminate opportunities

for direct or indirect transmission of

microorganisms from person toperson

Immune System Review

First line of defense from attack • Skin, mucus, stomach acid

• Non‐specific immune response• Responds the same way each time it is attacked regardless of what is attacking

• Not 100% effective

Adaptive Immune System   

Neutralize and kill the invading  antigen• Second line of body defense• More complex system• Actively identifies, seeks and destroys  antigens

Natural Immune System

Contact Transmission ‐ Indirect ContactContact Transmission ‐ Indirect Contact

Contact between a person and a contaminated object 

• Handle or re‐use a contaminated object• Not cleaning the ‘bell’ of the stethoset between uses on different hearing aids. 

• Touch contaminated doorknob

Contact Transmission‐ Droplet TransmissionContact Transmission‐ Droplet Transmission

Infectious microbes transmitted through water droplets through the air

• Speaking• Coughing

• Sneezing

Microbes come into direct or indirect contact with linings of eye, nose or mouth

Transmitted by droplet: COVID‐19, influenza, colds, respiratory syncytial virus (RSV) and some organisms causing pneumonia. 

• Coughing• Sneezing

Modes of Disease Transmission ‐ AirborneModes of Disease Transmission ‐ Airborne• Microorganisms remain suspended in the air for long 

periods of time and can be dispersed widely by air 

currents.

• Risk that all the air in a room may be contaminated. 

Microbe travels through air as droplet/dust particles from one person to another

Enters through respiratory system

Tuberculosis, Measles are transmitted airborne

Respiratory Hygiene/Cough Etiquette

CDC states Cough Etiquette:

• Implement measures to prevent the spread of respiratory infections from anyone in a health care setting with signs or symptoms.

• Post signs at entrances asking patients with symptoms of respiratory infection to:• Cover your mouth and nose when coughing or sneezing.• Use tissues and throw them away.• Wash your hands or use a hand sanitizer every time you touch your mouth or nose.

• Provide tissues and no‐touch receptacles for their disposal.• Provide resources for performing hand hygiene in or near waiting areas.

• Offer masks to symptomatic patients when they enter the dental setting.

• Provide space and encourage symptomatic patients to sit as far away from others as possible. Facilities may wish to place these patients in a separate area, if available, while waiting for care.

https://www.cdc.gov/oralhealth/infectioncontrol/faqs/respiratory‐hygiene.html

You now have a written infection control plan

Now you need to implement it

Be sure to CLEAN everything prior to disinfecting or sterilizing

• Cleaning removes the gross contamination of an object without killing germs

• Must clean an item prior to disinfecting or sterilizing

• Wipe down counters, chairs, tables, desk, workspaces, testing areas after each patient.

DISINFECTION• Kills a specific number of germs

• Number of germs killed is determined by the disinfectant used. 

• Audiology practice settings should use a HOSPITAL GRADE disinfectant. (Rutala, 1990)

• According to CDC hospital grade disinfectant is appropriate for killing COVID 19 • Towelette, spray, or soaking

o Be aware! • Some commercial products will affect integrity of the plastic, silicone rubber and acrylic • Not recommended for hearing aids, TDH‐39 

o EPA List N are good for disinfecting against COVID‐19 and other pathogens

Clean, DISINFECT or sterilize??

What should I disinfect??

EVERYTHING patient touches should be CLEANED and then DISINFECTED after each patient. 

Also if:

• If item does not touch blood 

• If item does not touch infectious substances

• Does not or cannot potentially break the skin

Clean

Clean, Disinfect or Sterilize??

What should I Sterilize??Any item comes into contact with a patient with:

•Potential infectious substance

•Cerumen, body fluid, blood, mucus, bodily fluid

•Open wound

•Any items that could break the skin

•Specula, Curette, wax loop

Steriliztion kills 100% of the vegetative microorganisms and  their endospores 100% of the time. 

(Infection Control in Audiology Practice, 2003)

• Uses high pressure saturated steam (121°C/249°F) for   15‐20 minutes• Can melt many items and instruments used in an audiology practice

Types of Sterilization in Audiology

• Heat under pressure‐ Autoclave • Cold Sterilization

• Chemicals approved for 

Sterilization

• Soak instruments in either:

• 2% glutaraldehyde 

• 7.5% hydrogen peroxide

Types of Cold Sterilization

• Wavicide‐ Glutaraldehyde solution 

• Re‐used for 28 Days

• 10 hour soaking time

• Does not need to be mixed

• Store in tightly covered tray

• Porous items cannot be soaked

• Use gloves when handling

• Sporax ‐ Hydrogen peroxide solution (>7.5% concentration)

• Reused for 21 days

• 6 hours soaking time

• Less hazardous than Wavicide

• Porous items cannot be soaked

• Uses gloves when handling

MSDS SHEETSWHERE DO I GET THEM?

• Obtained from manufacturer of the chemical.

WHERE NEED TO KEEP THEM?• OSHA requires that forms are stored near to the chemicals

Required by OSHA to have MSDS Sheets for each item in office  

• Impression material, earmold glues, Wavicide, Sporax, Otoease, hand sanitizer, etc.

Infection control begins prior to the patient’s visit

1) Spread your schedule out

• Need time in between patients to thoroughly clean/disinfect all surfaces in waiting room and patient rooms

2) Pre‐screen and inform patients prior to appointment

• Prescreening Questions:

• “Have you lost your sense or taste/smell, even if temporarily?”

• ”Do you have a fever at or above 100.4? Within the past 2 weeks?”

• ”Have you come into contact with someone that has been ill within the past 2 weeks?”

• Make sure patient aware of office policies 

• Must wear mask, wait in car, only one person with them, etc.

3) Establish an office policy on bringing others to the appointment.

• Bring someone only if need for accompaniment?

• Only person who appointment is for will be allowed in?

4) Establish if you want patients in the waiting area prior to appointment 

• Want to call the office when arrive?  

5) All patients must wear a mask

COVID‐19 has changed the way we look at infection control 

OFFICE SET UP•Waiting room‐ recommended all chairs to be at least 6 feet apart

• Consider a clear partition between staff and patients

• All staff should wear masks

• Gloves may be necessary

• Provide easily accessible hand sanitizer, tissues, trash cans for staff and patients.

• Enforce policy that all patients wear masks. 

• Place signs and posters providing instruction on hand hygiene, respiratory hygiene, and cough etiquette

• Disinfect all areas following patient leaving office prior to next scheduled appointment

• Consider plastic covering of all keyboards (easy disinfection)

Prior to appointment‐Screen your patients

Online screening tools are available for your patients.

Audiological Testingo All surfaces in the booth and equipment that touches the patient  should be wiped down with 

a disinfectant.  o Includes wiping the surfaces and equipment in the audiologist test area of the booth as 

well (audiometers, immittance, otoscope, computer keyboard) o Consider Plastic covering over buttons for equipment for easy disinfection (without 

worrying about ruining equipment)o Use of headphone coverso Use disposable items whenever possible (probe tips, insert earphones)

o Booth manufacturers are recommending leaving the booth empty with the door closed for a period between patients to allow for one full cycle of air exchange in the booth.

o This assumes the booth is attached to the HVAC system of the building (the preferred set‐up).

o If your booth is not attached to the HVAC system and uses fans, then the time for complete air exchange will be longer. Check with booth manufacturer to see complete cycle/refresh time  https://www.audiology.org/print/3915

Suggestions made by audiologists for Easier Infection Control Implementation

https://allcleanuv‐c.com/about‐uv‐c

Designed for sanitizing using UV‐C light:• headphones and headband• bone vibrators• otoacoustic emission probes, • headsets used in impedance testing• insert earphones• response buttons • Also be used with other frequently used type of headsets (audiologist headset, regular phone headset)

• Do not have to unplug  KEEP IN MIND THIS IS LINE OF SIGHT DISINFECTIONMUST BE CLEANED PRIOR

Options Available for Sanitization of  Audiological Equipment 

According to the manufacturer, the UV‐C lamp kills approximately 99.9% of most common viruses and bacteria.

Disinfecting cycle is 90 seconds.

ENG/VNG TestingPreparation: Personal Protective Equipment (PPE)

This evaluation has higher risk regarding transmission with direct contact.o Disposable gown over your scrubs/clothes. These are removed and disposed of between 

patients. o Wear gloves and change these between patients.o Surgical mask or N95 mask should always be used (many areas do not have enough N95s 

at this time, so you may need to use a surgical mask). o Face shields should be used given that a risk of aerosolized material is entry though the 

eyes. This could be a mask/shield combination, a separate face shield or plash rated goggles.

o Consider to wear designated work clothing (ie scrubs) on days performing vestibular testing that can changed out of when completed. 

o Consider wearing shoes that can be washed (rubber is one option) or wiped clean and remove these before entering your home.

ENG/VNG Testing• Consider using a bouffant cap over patient’s hair.• Patient must wear a mask• VNG Goggles: 

• Concern is for of transmission of COVID to the eyes as it is a vulnerable entry point for the virus• The Velcro should not make contact with the patient. • If available, use disposable foam goggle pads. 

•DISINFECTION of goggles after each patient•Use EPA‐approved list N disinfectant for silicone/rubber and strap

•(you can coat the strap with duct tape since it is a porous surface).• Lenses cannot be cleaned with disinfectant solvent due to infrared coating. 

•Wash with a solution of mild soap and warm water using a cotton ball. Rinse and dry with a cotton ball.

• Use a microfiber cloth to remove any remaining lint. •Clean between patients and at the end of day, return goggles to drawer only when they are cleaned.

•All equipment and surfaces that comes in contact with the patient and/or audiologist must be cleaned between patients.

Hearing Aids Hearing Aids 

NEVER accept a hearing aid from a patient with bare hands. 

Always use gloves, small cup or tissues

Disinfection of Hearing Aids

•Wipe once with  disinfecting wipe to clean the surface from debris, cerumen, etc. 

•Wipe again more thoroughly (with different part of wipe or a new wipe) to fully disinfect the aid(s) 

• Sanitize with UV‐C light• Remember UV is only line of sight disinfection

• What the light doesn’t touch, it does not disinfect

• Remove battery prior to usage

• If rechargeable, contact manufacturer if safe for usage

• Consult hearing aid manufacturer what is recommended
