Data Element


NACHC fully supports the CDC…

NACHC fully supports the CDC-NIOSH ODH model, and believes occupational health is central to understanding patient risk and context in a patient-centered way.

  1. We firmly support the use of the code systems and codes described by CDC-NIOSH and we can further state we are working with 3 clinical organizations using 3 different EHRs to implement these codes in production at this time.
  2. We support all comments of CDC-NIOSH and CSTE.

Request to reclassify.

CDC requests that the Job occupation and industry data elements (USCDI V3) be reclassified into a Job data class instead of Patient Demographics.


CDC requests the creation of Job and Usual Work data classes (USCDI V3 and Level 2) as submitted. The existing Work Information data class (Levels 1 and 2) includes data elements that are part of different “themes” (subjects) and are used differently. A Job (a work situation or position, including some volunteer positions) is a different subject than Usual Work (longest-held work). Most of the data elements for job or usual work are related to the respective theme (Job or Usual Work), not the person. This structure is borne out in the way the data elements are configured in interoperability standards and ensures that the data retain meaning and are not confused across themes. Job Occupation and Usual Occupation tie the respective themes to a person.


As data elements characterizing a Job, Usual Work or a person mature, having separate data classes will support data quality and reduce the possibility of the same information being collected in more than one way. For example, this proposed classification scheme could help clarify the variations in Employment Status. A person’s Employment Status (level 1, Work Information data class) is defined by ODH and supported by a value set that facilitates selection of a single entry about the person (mutually exclusive values). Employment, as defined by the Gravity Project (Comment level, SDOH data class), is based on the “type and conditions of employment,” i.e., Job. A person working multiple jobs, or who has retired and taken another job, cannot provide a single entry about themselves using the related value set under development. However, making the distinction between a person’s state of being employed vs conditions of employment within a Job would provide clarity in data collection and use.

CDC's Consolidated Comment

  • Similar to Occupation/Job Occupation, CDC requests that the original name for the draft V3 element “Occupation Industry” be used, i.e., “Job Industry.” “Occupation Industry” is confusing and “Job Industry” aligns with the many existing references to this data element, including interoperability standards, other ODH products, and discussions and presentations across a variety of audiences. In addition, “Job Industry” provides context; “Occupation Industry” doesn’t clarify if it’s about the person’s job, usual work, or another context. Clear and distinct naming of Job Industry will help the data to be useful for both clinical care and public health.
  •  CDC encourages ONC to accept this data element in USCDI V3, given its value for clinical care and public health. Substantial work has been done to provide informatics products (ODH) to support its implementation: an information model and vocabulary, how-to guides, and interoperability templates for consistent use in data exchange transactions.

CSTE Comment:

  • CSTE is very supportive of including work information in USCDI. It is important for assessing the increase in risk for conditions that might be ascribable to industry and occupation. However, specific job title and place of work are distinct variables and should also be collected and included in USCDI v3, including the address and phone number of each place the patient currently works.
