P.S.: It’s October! – guest post by Laurie Wells

Have you ever been asked to determine if a hearing loss is work-related or not? Or to review audiometric tests done by an audiometric technician at a work site? Or to identify an OSHA recordable hearing shift? While very few audiologists claim full time employment in an occupational setting (Sector Intelligence, 2014), it’s likely that most clinical audiologists have been involved in some way, shape, or form, with the sub-specialty some call occupational audiology.  On the surface, these types of requests from employers may seem straight forward; after all, it’s just a matter of complying with the regulatory requirements, right? Well, there is more than meets the ear when it comes to providing appropriate, efficacious occupational audiology services.  Sometimes, the issues are complicated and lack clearly defined answers.  Furthermore, conflict can arise between employers who want to avoid a recordable incident and employees who have hearing health concerns. What’s a good audiologist to do?

The term “professional supervisor” or PS refers to physicians and audiologists who engage with occupational hearing conservation programs (HCPs). Initially introduced by the Occupational Safety and Health Administration (OSHA), the term is also applies to the
Mine Safety and Health Administration (MSHA) and the Federal Railroad Administration problem audiogram(FRA).  A primary mandatory responsibility of the PS, as defined by OSHA, is to review “problem” audiograms. This can range anywhere from an audiogram that appears unreliable or invalid to a worker’s entire hearing history when a significant decrease in hearing is revealed. Regulatory agencies allow for technicians to conduct the air conduction threshold tests, however when problems arise, the employer must seek professional oversight.
caohcFor the past decade or so, the Council for Accreditation in Occupational Hearing Conservation (CAOHC) has offered a credential, called the Professional Supervisor of the Audiometric Monitory Program© (CPS/A) for qualifying audiologists and physicians. Earning this credential requires meeting the pre-requisites of professional and experiential qualifications, attending a one-day course, and passing an on-line exam.  While not a regulatory requirement, obtaining certification is an excellent way to get up-to-date information, relevant resources, and to have contact with subject matter experts. Holding the CPS/A designator can also be a prudent differentiator from one’s competitors and a credibility builder with prospective clients.

The scope of practice of a professional supervisor as outlined by CAOHC encompasses five categories of responsibility:

  • Establishment and supervision of an audiometric testing program
  • Review of audiograms
  • Determination of work-relatedness
  • Follow up of work-related auditory disorders
  • Management of an audiometric database

For more information on the CPS/A credential and upcoming course offerings, visit the CAOHC website: www.caohc.org. In addition, the recently updated Hearing Conservation Manual 5th Edition (CAOHC, 2014), provides detailed information useful for the professional supervisor and the occupational hearing conservationist.

The National Hearing Conservation Association (NHCA) also offers a resource, particularly helpful to those struggling with work-related determination decisions: NHCA Guidelines for Recording Hearing Loss on the OSHA 300 Log (NHCA, 2011). This document, written by a committee of professionals, addresses the OSHA regulatory requirements and offers practical recommendations for wording reports and working with employers.  The NHCA Guidelines can be retrieved from the NHCA website by clicking here.

Since October Is National Audiology Awareness Month & National Protect Your Hearing Month, it’s a perfect time to pursue the CPS/A credential, develop the expertise, and protect those noise‑exposed cochleas.  The next CAOHC PS Course is November 7, 2015 in Portland, OR.  Take action today to help prevent occupational hearing loss!

  1. AU; Thanks for sharing this information about the CAOHC. I did not know they existed. This is the sort of information that Frye can share not only with our domestic clients but also some of our International ones. Darroch
