OH3
Usual Work
The OH3 segment contains information about the occupation which the subject has held for the longest duration through his or her working history, at the point in time the statement is recorded. Longest-held occupations can be associated with conditions that develop slowly over time or even after the person is no longer performing that type of work, e.g., some respiratory conditions and cancers. It optionally includes a total duration observation, because a person can be in and out of a given occupation over time. In addition, knowing when the person began working in this occupation can provide information about potential exposures and allows the clinician to assess whether sufficient time has elapsed for a chronic condition to appear, i.e. the latency period. This guides appropriate use of screening tests to detect early disease. This segment may be related to either patient or to the Next of Kin.
