Infection Control in Audiology
Audiologists may handle hearing aids, earmolds, headphones, earphones, probe tubes, specula, curettes, and other instruments that come in direct or indirect contact with their patients. As a result, it is important that they protect themselves and their patients from infection.
The following is a compilation of resources that will help audiologists in all practice settings to establish and maintain an infection control program.

See pages I-8 and I-9 for information about infection control within program operations.
Infection Control Basics
Standard precautions were previously known as "universal precautions." The Centers for Disease Control and Prevention (CDC) recommend certain practices to prevent transmission of blood-borne pathogens. Annual training on these guidelines is mandated for all individuals who are recognized as being at-risk for occupational exposure to blood-borne pathogens.
Standard precautions include using hand hygiene and isolation precautions; wearing personal protective equipment; and following appropriate procedures for needle and sharps safety and disposal, medical waste disposal, and sterilization of reusable equipment.
CDC Guideline for isolation precautions: preventing transmission of infectious agents in healthcare settings 2007, standard precautions
Hand hygiene is the most effective way to prevent infection and is often considered the first line of defense against germs. Hand hygiene is important for the safety of health care workers and the patients they treat.
Isolation precautions are taken in health care settings to prevent the spread of an infectious agent from an infected or colonized patient to susceptible persons. The following guidelines for isolation precautions are intended to prevent transmission of infectious agents in healthcare settings:
Personal Protective Equipment
Personal protective equipment includes gloves, face masks, gowns, protective glasses, and other equipment used to provide a barrier of safety between the health care worker and the patient.
Needle Safety and Sharps Procedures/Disposal
Unfortunately, needlestick injuries occur in health care. Most needlestick injuries involve nurses, laboratory technicians, physicians, and housekeeping staff; however, all health care workers are susceptible.
