In this session we provided an introduction to and overview of CQL using a measure tour of the Public Comment review draft version of CMS 117 - Infant Vaccination.
This session covered the following topics:
- Hepatitis B Vaccination in an adolescent vaccine measure
- Turning a specific age during the measurement period
- Review of portions of CMS program measure drafts of 128, 159, 160, 161, and 169
This session covered the following topics:
- Matching Multiple Encounter Diagnoses
- Determining Arrival and Departure Time from Multiple Facility Locations
- Addressing Multiple Components of a Diagnostic Study
This session covered the following topics:
- Use of terminology operations and references in measures
- Use of multi-source queries
- QDM-CQL side-by-side review of CMS 68 and CMS 22
- Review of the common library functions available in the MAT
- Use of plural attributes in the upcoming QDM 5.3 release
- Use of the relatedTo attribute to implement
fulfillsin the upcoming QDM 5.3 release - Preliminary review of calculations with quantities
This session covered the following topics:
- Review of test measure 68: Medications documented
- Using exists with a singleton
- Using "choice" unions
- Review of test measure 111: continuous variable measures
- Combining "and" and "not"
- QDM vs CQL timing calculations
- Length Of Stay calculations
In this session we reviewed QDM 5.3, then discussed how result types are used and determined by expressions within CQL. We then reviewed issues with an expression of AMI8 and CMS31.
In this session we reviewed creation of libraries in the MAT, and then focused on the use of specific occurrences in a complex stroke measure, CMS72v5. We then used the Hospitalization function to demonstrate how to significantly simplify the logic of CMS72v5, avoiding the need to express the difference between inpatient encounters with and without prior emergency department visits in each criterion.
In this session, we focused on continuous variable measures, as well as demonstrated the use of common functions between measures that could potentially be added to a common library. Specifically, we worked CMS32, CMS55, and CMS111.
In this session, we expressed a complete measure (CMS146) in CQL and the MAT and produced the HQMF artifacts. The measure example was chosen for its use of specific occurrences. The "working" version of the example measure contains walkthrough text describing how the measure development proceeded. The final version of the example measure library is CMS146.cql.
In this session, we focused on valuesets expressed in measure CMS53. We also identified valuesets MultipleWithClauses. The "working" version of the example measure contains walkthrough text describing how the measure development proceeded.
In this session, we focused on valuesets expressed in measure CMS22. We also identified valuesets RelatedToGestationalAge. The "working" version of the example measure contains walkthrough text describing how the measure development proceeded.
In this session, we focused on valuesets expressed in the following measures:
-
CMS129 - Variable definition with Most Recent and attributes;
-
CMS104 -Denominator Exclusion with multiple discharge statuses;
-
CMS154 - Denominator Exclusion with timing relative to a Diagnosis;
-
CMS72 - Denominator Exception;
-
CMS105 – Discharged on Statin medication. The "working" version of the example measure contains walkthrough text describing how the measure development proceeded.
In this session, we discussed JIRA ticket CQM-1608 about VTE prophylaxis DuringObservation. We also focused on valuesets expressed 3 different measures – CMS117, CMS9, and CMS104. The "working" version of the example measure contains walkthrough text describing how the measure development proceeded.
In this session, we focused on valuesets expressed in 7 different measures – CMS143, CMS149, CMS165, CMS102, CMS 124, CMS65, and CMS 159. The "working" version of the example measure contains walkthrough text describing how the measure development proceeded.
In this session, we reviewed QDM version 4.3 and draft of QDM 5.0 for Clinical Quality Language Measure Developers. There are no examples associated with this session.
- This session covered changes to QDM 5.0, there are no examples associated
In this session, we focused on the use of CQL with FHIR and the differences between QDM version 4.2 and QDM version 5.0 for Negation Rationale and Timing Periods. We also discussed the definitions of Assessment Result Types, Care Goal, Transfer From, Transfer To, Cumulative Medication Duration, and Allergy and AdverseEvent.
In this session, we focused on the feedback received from Session 3. We looked at various criteria in the measure, CMS159, as presented in the clean version. The criteria discussed were Initial Population, $DepressionEncounter, $DepressionEncounterBH, $DepressionF2Fnomed, and $DepressionIndex. The "working" version of the example measure contains walkthrough text describing how the measure development proceeded.
The next part looked at a different measure, CMS9v5 (Exclusive Breastmilk Feeding), and described this episode-based measure in QDM and looked at how it is expressed in CQL. We looked at Population Criteria, Data Criteria, Supplemental Data Elements, and Risk Adjustment Variables as presented in the clean version. The "working" version of the example measure contains walkthrough text describing how the measure development proceeded.
In this session, we shared a new resource that will help explain all things CQL and will host the examples presented in the Cooking with CQL sessions. The link to the resource is https://github.com/cqframework/CQL-Formatting-and-Usage-Wiki/wiki/Cooking-with-CQL-Examples and is titled CQL Formatting and Usage Wiki.
We also focused on describing initial populations as seen in the “Clean Version” using examples from the following measures: Patient-based Proportion Measure
- CMS117 – Age and encounter;
- CMS125- Age, sex, and encounter;
- CMS129 – Diagnosis overlaps MP and sex;
- CMS138 – Count of encounters;
- CMS135 - Count of encounters with diagnosis;
- CMS136 – Cumulative medication;
- CMS140 – First occurrence;
- CMS154 – Satisfies any with satisfies all;
- CMS159 – Timing, diagnosis, satisfies; Episode of Care Proportion Measure;
- CMS53 – Diagnosis overlaps encounter;
- CMS113 – Procedure during encounter; Episode of Care Continuous Variable Measure;
- CMS55 – Encounter relative to another encounter;
- CMS111 – Encounter relative to another encounter Procedure-based Proportion Measure;
- CMS133 – Procedure relative to MP end.
The "working" version of the example measure contains walkthrough text describing how the measure development proceeded.
The Cooking with CQL sessions provides guidance on how to use CQL to express measures. In this session, we focused on how to calculate age in CQL by describing various criteria using examples from the following measures:
-
CMS132 – Initial Population;
-
CMS104 - Initial Population, $EncounterInpatientNonElective;
-
CMS122 - Initial Population;
-
CMS113 - Initial Population, $EncounterInpatient;
-
CMS2 - Initial Population;
-
CMS124 - Initial Population;
-
CMS153 - Initial Population, Stratification 1, Stratification 2;
-
CMS82 - Initial Population, Numerator.
In this session, we demonstrated how to build an eCQM using CQL. The measure focused in this session is the PHQ-9 Scoring examples, as there are difficult criteria of this measure to express in CQL. Specifically, we focused on understanding “Measurement Period” using QDM version 4.2. In example 1, we discussed the measure “utilization of the PHQ-9 to monitor Depression Symptoms for Adolescents and Adults,” we explored the Measurement Period as defined in “In Initial Population”, “Depression Encounter”, “Depression Diagnosis”, “Assessment Period 1”. “Assessment Period 2”, and “Assessment Period 3.” We also looked at different numerator and stratification examples.
Example 2 looked at the measure “Depression Remission or Response for Adolescents and Adults” using the “Measurement Period” and evaluated “Initial Population”, Depression Followup, Depression Remission, Depression Response, Depression Encounter, and Depression Index.
