Noise and Occupational Hearing Loss
Partner with NIOSH Occupational Hearing Loss Surveillance Program
NIOSH partners with audiometric service providers and others to share de-identified individual level worker data with NIOSH, including audiograms and related information.
- Audiometric service providers
- Occupational health clinics
- Hospitals and others who conduct worker audiometric testing
- Private companies conducting in-house worker audiometric testing
What Are the Benefits for Partners?
Partners will support vital hearing loss surveillance and research and get a first look at study results before they are released to the public.
What Kind of Data Will Be Requested?
Partners must de-identify the data and assign an arbitrary number or code to each worker. This number/code must remain consistent for the worker from year to year so NIOSH can link all of the audiograms for each worker.
- Threshold values for frequencies 500, 1000, 2000, 3000, 4000, 6000, and 8000 Hertz
- Date of birth
- Test date
- Date of hire (if available)
- Race/ethnicity (if available)
- Smoking status (if available)
- Occupation information (if available)
- Industry information (if available)
- Exposure data (if available and linked to the audiometric data)
How Will the Data Be Used?
The data will be added to a national repository for occupational hearing loss surveillance and research. It will be used to
- Measure the incidence and prevalence of hearing loss among workers.
- Identify industries with the highest and lowest risks of hearing loss.
- Measure hearing loss trends among and within industries.
- Examine workplace factors related to hearing loss.
- Guide workplace interventions and research.
- Establish baseline estimates to evaluate the effectiveness of hearing loss prevention efforts.
Main Steps for Sharing Data
A NIOSH representative will guide you through each step of the data sharing process. Steps include:
- The industry (e.g., Mining) for each audiogram is identified and assigned a North American Industry Classification System (NAICS) code.
- The partner decides whether the partner or NIOSH will assign these NAICS codes. The partner merges the NAICS codes with the audiometric data so that a NAICS code is associated with each audiogram.
- The NIOSH representative assists the partner in securely transferring the de-identified electronic data to NIOSH.
- NIOSH may request additional data from the partner in future years, and the process begins again.
Are the Names of Partners Released?
No, the names of partners will not be released unless NIOSH is compelled by law to reveal this information.
Is It Legal for Data Providers to Share Data with NIOSH?
Yes, the HIPAA Privacy Rule recognizes the legitimate need for public health authorities to have access to protected health information to carry out their public health mission. Accordingly, the HIPAA Privacy Rule permits covered entities to disclose protected health information, without authorization of the individual to whom the information pertains, to a public health authority, such as NIOSH, that is “. . . authorized by law to collect or receive such information for the purpose of preventing or controlling disease, injury or disability . . .” [See 45 CFR 164.512(b)(1)(i)].
