Definitions for the odh-PastOrPresentJob resource profile.
Guidance on how to interpret the contents of this table can be found here
0. Observation | |
Definition | Related data elements for a current or previous job, as reported by the person, i.e., a work situation or position held for a specified time period. A person can have more than one job at the same time and multiple jobs over time, so the data related to each job must remain in the record in perpetuity. Each job should be recorded in a separate instance of PastOrPresentJob. A person's job can be a social determinant of their health and information about a person's job can support patient care, population health, and public health. In patient care, knowledge of a person's past or present job(s) can impact recognition, diagnosis, management, and treatment of injuries and illnesses. These data also can be used for clinical decision support and to prompt discussion of preventive care measures. For example, a record of jobs that require prolonged time in the sun might prompt a health care provider to inquire if the person wears protective clothing or sunscreen while working. At a minimum, it is important to have a record of a person's current job(s); i.e., the job(s) in which a person is engaged at the time that he or she presents to a health care provider, regardless of duration, and to retain that information over time. In the event a person recently stopped working (e.g. retired without another job, became unemployed or disabled and unable to work), the most recent job(s) is used instead of the current job(s). |

0. Observation | |
Definition | Related data elements for a current or previous job, as reported by the person, i.e., a work situation or position held for a specified time period. A person can have more than one job at the same time and multiple jobs over time, so the data related to each job must remain in the record in perpetuity. Each job should be recorded in a separate instance of PastOrPresentJob. A person's job can be a social determinant of their health and information about a person's job can support patient care, population health, and public health. In patient care, knowledge of a person's past or present job(s) can impact recognition, diagnosis, management, and treatment of injuries and illnesses. These data also can be used for clinical decision support and to prompt discussion of preventive care measures. For example, a record of jobs that require prolonged time in the sun might prompt a health care provider to inquire if the person wears protective clothing or sunscreen while working. At a minimum, it is important to have a record of a person's current job(s); i.e., the job(s) in which a person is engaged at the time that he or she presents to a health care provider, regardless of duration, and to retain that information over time. In the event a person recently stopped working (e.g. retired without another job, became unemployed or disabled and unable to work), the most recent job(s) is used instead of the current job(s). Measurements and simple assertions made about a patient, device or other subject. |

2. Observation.implicitRules | |
Definition | A reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content. Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc. |
Short | A set of rules under which this content was created |
Comments | Asserting this rule set restricts the content to be only understood by a limited set of trading partners. This inherently limits the usefulness of the data in the long term. However, the existing health eco-system is highly fractured, and not yet ready to define, collect, and exchange data in a generally computable sense. Wherever possible, implementers and/or specification writers should avoid using this element. Often, when used, the URL is a reference to an implementation guide that defines these special rules as part of it's narrative along with other profiles, value sets, etc. |

4. Observation.extension | |
Definition | An Extension May be used to represent additional information that is not part of the basic definition of the resource. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. |
Short | ExtensionAdditional content defined by implementations |
Comments | There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone. |

10. Observation.modifierExtension | |
Definition | May be used to represent additional information that is not part of the basic definition of the resource and that modifies the understanding of the element that contains it and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions. Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself). |
Short | Extensions that cannot be ignored |
Comments | There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone. |

Requirements | Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions. |

Definition | The actual focus of an observation when it is not the patient of record representing something or someone associated with the patient such as a spouse, parent, fetus, or donor. For example, fetus observations in a mother's record. The focus of an observation could also be an existing condition, an intervention, the subject's diet, another observation of the subject, or a body structure such as tumor or implanted device. An example use case would be using the Observation resource to capture whether the mother is trained to change her child's tracheostomy tube. In this example, the child is the patient of record and the mother is the focus. |

Comments | Null or exceptional values can be represented two ways in FHIR Observations. One way is to simply include them in the value set and represent the exceptions in the value. For example, measurement values for a serology test could be "detected", "not detected", "inconclusive", or "specimen unsatisfactory". The alternate way is to use the value element for actual observations and use the explicit dataAbsentReason element to record exceptional values. For example, the dataAbsentReason code "error" could be used when the measurement was not completed. Note that an observation may only be reported if there are values to report. For example differential cell counts values may be reported only when > 0. Because of these options, use-case agreements are required to interpret general observations for null or exceptional values. |

Comments | "Null" or exceptional values can be represented two ways in FHIR Observations. One way is to simply include them in the value set and represent the exceptions in the value. For example, measurement values for a serology test could be "detected", "not detected", "inconclusive", or "test not done". The alternate way is to use the value element for actual observations and use the explicit dataAbsentReason element to record exceptional values. For example, the dataAbsentReason code "error" could be used when the measurement was not completed. Because of these options, use-case agreements are required to interpret general observations for exceptional values. |

0. Observation | |||||
Definition | Related data elements for a current or previous job, as reported by the person, i.e., a work situation or position held for a specified time period. A person can have more than one job at the same time and multiple jobs over time, so the data related to each job must remain in the record in perpetuity. Each job should be recorded in a separate instance of PastOrPresentJob. A person's job can be a social determinant of their health and information about a person's job can support patient care, population health, and public health. In patient care, knowledge of a person's past or present job(s) can impact recognition, diagnosis, management, and treatment of injuries and illnesses. These data also can be used for clinical decision support and to prompt discussion of preventive care measures. For example, a record of jobs that require prolonged time in the sun might prompt a health care provider to inquire if the person wears protective clothing or sunscreen while working. At a minimum, it is important to have a record of a person's current job(s); i.e., the job(s) in which a person is engaged at the time that he or she presents to a health care provider, regardless of duration, and to retain that information over time. In the event a person recently stopped working (e.g. retired without another job, became unemployed or disabled and unable to work), the most recent job(s) is used instead of the current job(s). | ||||

20. Observation.modifierExtension | |||||
Definition | May be used to represent additional information that is not part of the basic definition of the resource and that modifies the understanding of the element that contains it and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions. Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself). | ||||

Short | The reason that there is no value available for the Occupation. | ||||
Comments | Null or exceptional values can be represented two ways in FHIR Observations. One way is to simply include them in the value set and represent the exceptions in the value. For example, measurement values for a serology test could be "detected", "not detected", "inconclusive", or "specimen unsatisfactory". The alternate way is to use the value element for actual observations and use the explicit dataAbsentReason element to record exceptional values. For example, the dataAbsentReason code "error" could be used when the measurement was not completed. Note that an observation may only be reported if there are values to report. For example differential cell counts values may be reported only when > 0. Because of these options, use-case agreements are required to interpret general observations for null or exceptional values. | ||||

Comments | "Null" or exceptional values can be represented two ways in FHIR Observations. One way is to simply include them in the value set and represent the exceptions in the value. For example, measurement values for a serology test could be "detected", "not detected", "inconclusive", or "test not done". The alternate way is to use the value element for actual observations and use the explicit dataAbsentReason element to record exceptional values. For example, the dataAbsentReason code "error" could be used when the measurement was not completed.

An observation may have both a value (e.g. an Apgar score) and component observations (the observations from which the Apgar score was derived). If a value is present, the datatype for this element should be determined by Observation.code.

Definition | Provides a reason why the expected value in the element Observation.component.value[x] is missing. | ||||
Short | Why the component result is missing | ||||
Comments | "Null" or exceptional values can be represented two ways in FHIR Observations. One way is to simply include them in the value set and represent the exceptions in the value. For example, measurement values for a serology test could be "detected", "not detected", "inconclusive", or "test not done". The alternate way is to use the value element for actual observations and use the explicit dataAbsentReason element to record exceptional values. For example, the dataAbsentReason code "error" could be used when the measurement was not completed. Because of these options, use-case agreements are required to interpret general observations for exceptional values. | ||||

Comments | Most observations only have one generic reference range. Systems MAY choose to restrict to only supplying the relevant reference range based on knowledge about the patient (e.g., specific to the patient's age, gender, weight and other factors), but this might not be possible or appropriate.
