|Data Element Information|
|Rationale for Separate Consideration||A Sex For Clinical Use (SFCU) is intended to be a context-specific summarization of relevant clinical observations. The existing USCDI data class of SFCU that includes a general (context independent) SFCU data element is problematic because neither is context specific. A better approach is to have a context specific SFCU where the specific intended use is clear. By creating specific context dependent SFCU data elements like one for clinical tests, each SFCU value will be clearly independent and understood to relate only to the context defined, a test in this case.
There is a need for other context specific SFCU data elements to clarify that SFCU can be included to support other data classes. Each of these unique data elements should be considered as a unique element representing a common approach.
We expect industry maturity for SFCU to vary for different data classes. There is already some industry adoption of Patient SFCU. We expect Laboratory SFCU adoption may increase relatively quickly. SFCU for other data classes may require more investment by the industry to achieve maturity. Having separate data elements for the different contextual SFCUs allows the industry to advance the maturity of these contextual SFCU concepts independently.
|Use Case Description(s)|
|Use Case Description||The Sex For Clinical Use categorization is intended to communicate the summary sex category (such as Male or Female) that would best align with the expected observations based upon the identified observation context used to determine the value. When male or female is not a proper categorization, then “Specified” is to be used to indicate that default behavior that is safe for both male and female populations should be used, or a provider should review treatment options individually with the patient.
A medication SFCU is a sex category that is intended to represent the proper sex categorization that is to be applied for the specific medication order under consideration independent of the patient gender identity or other clinical sex values that may be known about the patient. In this way a test can use the proper reference range, therapeutic, or diagnostic parameters appropriate for the specific clinical situation known for the patient. A test-specific SFCU can communicate unique organ inventory or hormonal findings by exchanging “standard” sex categories even when the system using this information does not have access to the more discrete observations or those observations are masked due to privacy concerns. Patients with organ system inventories or hormonal results that are not aligned with traditional values associated with male or female can have multiple different SFCU values depending on the SFCU context under consideration.
|Estimate the breadth of applicability of the use case(s) for this data element||Current systems that support Ask At Order Entry (AOE) for medication ordering are capturing similar data and can support a medication order-specific clinical sex value. Even though an AOE value is very similar, very few systems have implemented a medication order-specific sex for clinical use value that is persisted for reporting and understood to be a unique value for that specific test. In situations where unique patient characteristics are known that affect medication order processing, in lieu of an SFCU systems exchange a general patient sex or gender value and then modify this value if needed to properly perform or result the test. It is therefore clear that defining a specific data element for a clinical sex value reduces ambiguity and the risk or incorrect assumptions.|

|Current Use||Not currently captured or accessed with an organization|
|Extent of exchange||N/A|
|Restrictions on Standardization (e.g. proprietary code)||No restrictions other than changing the perceived approach to this common element.|
|Restrictions on Use (e.g. licensing, user fees)||None|
|Privacy and Security Concerns||SFCU will likely contain information with privacy concerns. But it is our expectation that contextual SFCU could achieve desired clinical outcomes without revealing discrete organ inventory and other physiological measurements for many patients. By not requiring those discrete observations, use of SFCU may have a reduced privacy impact and provider documentation burden.|
|Estimate of Overall Burden||Most systems will require updates to implement the SFCU element, differentiating it by context and previously recorded Sex information.|
|Other Implementation Challenges||Adoption of this element by governmental reporting systems.|
Medication Sex For Clinical Use
A clinical sex category based upon detailed observations typically associated with the designation of male and female that is to be used for determining clinical parameters associated with a medication order.
