Resource Effective Period |
The period during which the resource content was or is planned to be effective. |
Questionnaire Item Control |
The type of data entry control or structure that should be used to render the item. Certain item controls only make sense for certain types of items. For example, a radio button doesn’t make sense for a question where repeats=true; few systems will know how to implement a ‘slider’ control if the question type is ‘Attachment’, etc. Form fillers are allowed to ignore item controls that don’t make sense (or that they don’t know how to handle) for the type of item the extension appears on. If the extension is ignored, the form filler will use whatever display control it supports that works best for the type of item present. Similarly, form authoring tools may raise validation issues or prohibit the selection of certain control types based on the characteristics of the item. |

This is an equivalent of the string on which the extension is sent, but includes additional XHTML markup, such as bold, italics, styles, tables, etc. Existing restrictions on XHTML content apply. Note that using markdown allows for greater flexibility of display. Like the Resource Narrative, this extension may reference binary resources for image content (see note about referencing images) |

Patient Sex For Clinical Use |
Sex for Clinical Use (SFCU) Overview Sex for Clinical Use is a categorization of sex derived from observable information such as an organ inventory, recent hormone lab tests, genetic testing, menstrual status, obstetric history, etc. This property is intended for use in clinical decision making and indicates that treatment or diagnostic tests should consider best practices associated with the relevant reference population. While clinical decision-making processes could account for the specific physiological or anatomical attributes of the patient, there are several practical considerations, such as patient privacy and limited capabilities of existing systems which create the need for a categorization that is easy to exchange. The Sex for Clinical Use categorization is intended to bridge the gap between the hypothetical ideal and the practical needs of operational systems. Sex for Clinical Use (SFCU) Contexts Sex for Clinical Use is a contextual concept. For example, a patient may generally be categorized as male, but for a specific lab test, the resulting lab should use the reference ranges associated with a female reference population. In this case, systems may provide a patient-context sexForClinicalUse that acts as a ‘default’ for most care and annotate the lab order with a context-specific sexForClinicalUse. Systems may determine what enclosing contexts are useful, but Patient, Encounter and EpisodeOfCare are three enclosing contexts that may often apply. The sexForClinicalUse extension can be used to communicate a clinical sex category on the on relevant clinical resources (e.g., DiagnosticReport, ServiceRequest) or enclosing contexts (e.g., Patient, Encounter, EpisodeOfCare). Sex for Clinical Use (SFCU) Categorization For ease of interoperability, a patient’s sex for clinical use is constrained to four possible categories. Any patient for which special considerations apply should be categorized as ‘Specified’. The ‘Specified’ category is often represented as ‘Other’ in existing systems. Female - Available data indicates that diagnostics, analytics, and treatments should consider best practices associated with female reference populations. Male - Available data indicates that diagnostics, analytics, and treatments should consider best practices associated with male reference populations. Specified - Available data indicates that diagnostics, analytics, and treatment best practices may be undefined or not aligned with existing sex-derived reference populations. Individuals or systems providing care should either use default behavior that is safe for both male and female populations, individually review treatment options with the patient, or carefully inspect relevant observations before proceeding with treatment. Unknown - The sex for clinical use cannot be determined because there are no relevant evidence or documentation, or the evidence or documentation are not sufficient to determine a value. Sex for Clinical Use (SFCU) History and Practices Prior to the definition of Sex for Clinical Use as a concept, systems may have used administrative gender as an approximation of patient-level sex for clinical use. This practice required pre-coordination among exchange parters to explicitly overload the administrative sex concept for use as a clinical sex concept. In cases where there was no pre-coordination, some systems may have incorrectly inferred information about a patient’s clinical sex from administrative gender. In the context of ordering workflows, systems may use Ask at Order Entry (AOE) questions to collect concepts similar to sex for clinical use. |

MessageHeader Response Request |
This extension enables the capability currently available through MSH-16 (Application Level acknowledgement) in HL7 Version 2 to declare at a message instance level whether a response is required or only upon error or success, or never. |

Observation Secondary Finding |
Secondary findings are genetic test results that provide information about variants in a gene unrelated to the primary purpose for the testing, most often discovered when Whole Exome Sequencing (WES) or Whole Genome Sequencing (WGS) is performed. This extension should be used to denote when a genetic finding is being shared as a secondary finding, and ideally refer to a corresponding guideline or policy statement. For more detail, please see: https://ghr.nlm.nih.gov/primer/testing/secondaryfindings. |

Observation Time Offset |
A specific offset time in milliseconds from the stated time in the Observation.appliesDateTime to allow for representation of sequential recording of sampled data from the same lead or data stream. For example, an ECG recorder may record sequentially 3 leads four time to receive 12-lead ECG, see ISO 22077. |
Observation Precondition |
Other preceding or concurrent observations that must be known to correctly interpret the observation. For example, an fiO2 measure taken alongside of a SpO2 measurement. See the Observation notes section for additional guidance. |
Observation Device Code |
A code representing the the type of device used for this observation. Should only be used if not implicit in the code found in |
