Low Molecular Weight Heparin For Vte Prophylaxis Administered

Description:

Clinical Focus: This set of values represents medications used for VTE prophylaxis. The medications are low molecular weight heparins. The medications included in this value set are administered parenterally.

Data Element Scope: The intent of this data element is to identify patients who are on low molecular weight heparin therapy as VTE prophylaxis. Using the Quality Data Model, this data element maps to the Medication category.

Inclusion Criteria: Only include RxNorm codes which specifically represent low molecular weight heparins which are administered parenterally.

Exclusion Criteria: None.

Subject constrained to the Low Molecular Weight Heparin for VTE Prophylaxis

QDM Datatype: MedicationAdministered

Data elements that meet criteria using this datatype should document that the medication indicated by the QDM category and its corresponding value set was actually administered to the patient. Timing: The Relevant Period addresses: startTime = when a single medication administration event starts (e.g., the initiation of an intravenous infusion, or administering a pill or IM injection to a patient); stopTime = when a single medication administration event ends (e.g., the end time of the intravenous infusion, or the administration of a pill or IM injection is completed - for pills and IM injections, the start and stop times are the same) NOTE – Measure developers should address multiple administrations over a period of time using CQL logic. Refer to Special Cases in Appendix A (Section A.3) for scenarios to consider in calculating cumulative medication duration.

LowMolecularWeightHeparinForVteProphylaxis

AuthorDatetime

The time the data element was entered into the clinical software. Note, some datatypes include both Relevant Time and Author dateTime attributes. The purpose is to accommodate Author dateTime if the actual start and stop times are not available when evaluating for feasibility, and also to allow specification of a time for Negation Rationale.

RelevantPeriod

Relevant Period addresses the time between the start of an action to the end of an action. Each datatype using relevant period defines specific definitions for the start and stop time for the action listed.

NegationRationale

Indicates the reason that an action was not performed. Only QDM datatypes that represent actions (e.g., performed, recommended, communication, order, dispensed) allow the “negation rationale” attribute. The intent is to indicate a justification that such action did not happen as expected. This attribute specifically does not address the presence or absence of information in a clinical record (e.g., documented absence of allergies Vs lack of documentation about allergies). The syntax in the human readable HQMF is address in CQL examples and in the MAT User Guide. Prior versions of QDM used the syntax, “Procedure, Performed not done.” QDM 5.0 DRAFT uses the syntax, “Procedure, not Performed.” Note: Some datatypes include both Relevant Time and Author dateTime attributes. The purpose is to accommodate Author dateTime if the actual start and stop times are not available when evaluating for feasibility, and also to allow specification of a time for Negation Rationale.
