The modeling seems confusing. I would assume that an individual might have one or more "jobs" or occupations each of which should have a start and stop date. The term "retirement" in the class model (page 5) seems to be uniquely assigned to the patient and not to any particular "job" - I.e., each "job" has a start and stop date but the patient has a retirement date. The description on page 9 states retirement date is "the month and year that a person self-identifies as retired (4). A person may have more than one retirement date and it should be possible to enter at least two dates. Retirement dates should not be considered as a person's employment status, as a person could be retired from one job and employed in another."

A person may be partially retired, retired from one occupation, and completely retired, I.e., have no occupation - but even in full "retirement" may have avocational/volunteer activities that cause the person to be at risk for various "occupational" concerns.  It seems that even the consideration of retirement is too vague and confusing, and it is easily conflated to mean many different things.  It seems that a cleaner approach is to address each "job" or occupation with a status such as "active," "inactive," "partially active," "completed" or some such reference, and that each "Status" has a start and stop time.  The concept of "retirement" is a statement potentially derived from these one or more "jobs" that have a required status.   What the DAM seems to suggest is a patient belief or attestation of a retired status as a person, but that should be clearly defined as a patient's self-assessment or belief. It is not any indication of ODH risk but perhaps more of a social determinant.
