["Medication, Order": "Antithrombotic Therapy"]

eCQM Data Element

Performance/Reporting Period
2020
Value Set Description from VSAC
Clinical Focus: This value set contains concepts that represent anticoagulant and antiplatelet medications used to reduce stroke mortality and morbidity.
Data Element Scope: This value set may use the Quality Data Model (QDM) category related to Medication. The intent of this data element is to identify patients who receive antithrombotic therapy following stroke.
Inclusion Criteria: Includes only relevant concepts associated with single and multi-ingredient drugs. Oral, rectal, and injectable dose forms should be included. Antithrombotic medications includes only relevant concepts associated with anticoagulants and antiplatelet drugs.
Exclusion Criteria: Excludes codes for enoxaparin and heparin generally given for VTE prophylaxis.

Constrained to codes in the Medication, Order: Antithrombotic Therapy value set (2.16.840.1.113883.3.117.1.7.1.201)

QDM Datatype and Definition (QDM Version 5.4)

"Medication, Order"

Data elements that meet criteria using this datatype should document a request to a pharmacy to provide the medication indicated by the QDM category and its corresponding value set.

Timing: The Author dateTime is the time the order is signed.

Timing: The Relevant Period addresses:

  • startTime - when the first administration of the medication is expected. The first administration may be expected at the time of the order or at a specified future date (i.e., the active time for the order); such information should be identified in the medication order. If the startTime is not specified in the order, the startTime defaults to the Author dateTime (the time the order is signed).
  • stopTime - when the medication supply provided by the medication order is expected to be completed, including all fulfillments covered by the number of refills.

Note that when calculating cumulative medication duration, the stopTime may be present directly in the medication order. If the stopTime is not available, the duration in days is the difference between the Relevant Period start and stop times multiplied by (1 + the number of refills).

QDM Attributes

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.

negationRationale

The QDM attribute, negation rationale 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 versus lack of documentation about allergies). QDM assumes that any information expected will be in a clinical record. The situation is different when something that normally would be expected to be done is specifically not done because of a valid clinical reason (such as the patient is allergic, they are suffering from a complication, or some other rationale. In this case, the 'thing not done' is rarely documented, especially as a code, in the patient record. To express such lack of evidence, an eCQM author should use a CQL 'not exists' expression noted in the examples, and they must also capture the Negation rationale to capture a reason for the absence, i.e., the reason must be included to qualify as a negation rationale type expression. The syntax in the human readable HQMF is described in CQL examples and in the MAT User Guide. Prior versions of QDM used the syntax, 'Procedure, Performed not done.' QDM 5.5 uses the syntax, 'Procedure, not Performed' and this is then associated with either a DRC or a value set used to identify 'the expected thing,' that in this case was not done. Negation Rationale attribute value indicates a one-time documentation of a reason an activity is not performed. Negation of QDM datatype-related actions for a reason always use the author dateTime attribute to reference timing.

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.
