OH2 - Past Or Present Job Segment

The OH2 segment is used to communicate the information about a job or jobs which the subject currently holds or has held in the past. It includes related observations about the occupation (type of work), the type of business (industry) in which that occupation is performed, supervisory level (including military pay grade), and the employer's name and location. It should also include observations about the job's compensation and sector employment type (e.g., paid work, self-employed, volunteer) and work schedule, and may also contain observations for job duties and occupational exposures. The type of work a person performs (occupation) and their industry (type of business in which they work) are critical data elements for patient care, population health, and public health, with the current information being the most important. In the health care encounter, current occupation and industry are important because they provide information regarding the exposures a person may have to substances/environments/hazards that may cause illness/injury or may impact the treatment plan. The combination of occupation and industry serves as a key indicator of the person’s work environment. The segment is designed to ensure that these data remain associated with one-another in perpetuity, even if multiple jobs are included.

This segment may relate either to the patient or to the Next of Kin.

The intent is for the segment to be allowed to repeat within a message definition to enable a job history for the person.

Examples:

A person/patient may currently hold a job as carpenter, and previously held a job as a painter. This would be represented by repeating OH2 segments.

OH2-1: Set ID (SI) 03522

Definition: This field contains the number that identifies the OH2 segment instances in message structures where the OH2 segment repeats. For the first occurrence of the segment, the sequence number shall be one, for the second occurrence, the sequence number shall be two, etc. If the subject of the OH2 segment changes (e.g. Patient vs Next of Kin) the Set ID sequence will be reset.

OH2-2: Action Code (ID) 00816

Definition: This field contains a code defining the action to be taken for this segment. It allows this segment to be sent to delete or update, for example, previously sent information. Refer to HL7 Table 0206 – Segment Action Code in Chapter 2C, Code Tables, for valid values.

OH2-3: Entered Date (DT) 03524

Definition: This field records the date that the information was entered into the patient record.

OH2-4: Occupation (CWE) 03525

Definition: This field contains a code defining the occupation in which an individual is engaged in for the job recorded in this segment, regardless of duration. Refer to HL7 Table 0958 – Occupation Code in Chapter 2C, Code Tables, for suggested values. In the US, this field should use the Occupation CDC Census 2010 codes published at https://phinvads.cdc.gov/vads/ViewValueSet.action?oid=2.16.840.1.114222.4.11.7186

OH2-5: Industry (CWE) 03526

Definition: This field contains a code defining the industry in which an individual is engaged for the job recorded in this segment, regardless of duration. Refer to HL7 Table 0955 – Industry Code in Chapter 2C, Code Tables, for suggested values. In the US, this field should use the Industry CDC Census 2010 codes published at https://phinvads.cdc.gov/vads/ViewValueSet.action?oid=2.16.840.1.114222.4.11.7187

OH2-6: Work Classification (CWE) 03527

Definition: This field contains a code defining the work classification associated with the job of a person recorded in this segment. Refer to HL7 Table 0959 – Work Classification Code in Chapter 2C, Code Tables, for suggested values.

OH2-7: Job Start Date (DT) 02494

Definition: This field asserts when the job began.

OH2-8: Job End Date (DT) 02495

Definition: This field asserts when the job ended. If the job is current, Job End Date shall be empty.

Note: The Employment Status End Date SHALL not be greater than the date noted in OH2-3 Entered Date.

OH2-9: Work Schedule (CWE) 03528

Definition: This field contains a code defining the work schedule associated with the job of a person recorded in this segment. Describes an individual's typical arrangement of working hours for a job. For example, work schedule may capture that an individual typically works a regular day shift, evening shift, or night shift. It can also specify if an individual has another type of schedule such as a rotating shift, split shift, etc. In healthcare settings, knowledge of a patient's typical work schedule may assist in diagnosis of healthcare issues related to irregular work hours or sleep patterns. It may also assist in determining appropriate treatment and prevention plans that will coordinate with the patient's work schedule. Refer to HL7 Table 0954 – Work Schedule Code in Chapter 2C, Code Tables, for suggested values.

OH2-10: Average Hours worked per Day (NM) 03529

Definition: This field asserts the average hours worked per day for the job of a person recorded in this segment.

OH2-11: Average Days Worked per Week (NM) 03530

Definition: This field asserts the average days worked per week for the job of a person recorded in this segment.

OH2-12: Employer Organization (XON) 03531

Refer to HL7 Table 0956 – Supervisory Level Code in Chapter 2C, Code Tables, for suggested values. In the US, this field should use the Job Supervisory Level or Pay Grade (ODH)codes published at https://phinvads.cdc.gov/vads/ViewCodeSystem.action?oid=2.16.840.1.114222.4.11.7613

OH2-15: Job Duties (ST) 03533

Definition: This field lists the regular actions performed at work. For example, a person may have the occupation of “construction laborer” and his specific job duties are to carry construction supplies. Specific job information is important in the healthcare setting because it provides information regarding hazards to which a person may have been exposed, which is pertinent to treatment and prevention. This field may repeat to list multiple job duties, or the job duties may be compiled as a single narrative.
