eCQM: Electronic Clinical Quality Measure
eCQMs are quality measures specified in the Clinical Quality Language (CQL) standard and calculated directly from structured EHR data — replacing the chart-abstracted CQM workflow that dominated quality reporting prior to 2014.
What is an eCQM?
eCQMs are quality measures whose specification, value sets, and logic are defined in machine-readable form (CQL — Clinical Quality Language). Where the original CQMs required manual chart abstraction by trained nurses, eCQMs are designed to compute directly from structured EHR data — diagnoses, procedures, medications, lab results, vitals — without manual review.
How eCQMs differ from chart-abstracted measures
- Speed — eCQMs can be calculated continuously from EHR data; chart-abstracted measures require a sampling and review cycle.
- Cost — abstraction nurses cost ~$80K/year per FTE; eCQM workflow is largely automated.
- Coverage — eCQMs cover the full eligible patient population; chart-abstracted measures sample.
- Documentation precision — eCQMs only count what's in structured fields. Free-text documentation that would have qualified under chart abstraction may not count.
Where eCQMs apply
eCQMs are used across the MIPS Quality category, the Hospital Inpatient Quality Reporting program, the Promoting Interoperability program (electronic submission requirement), Medicaid quality reporting in many states, and an increasing share of value-based contracts.
Where Vizier fits
Vizier calculates eCQMs from EHR-pulled data using the CMS-published CQL specifications, with the same denominator, exclusion, and numerator logic CMS will apply at submission. The continuous calculation surfaces drift mid-year; the documentation gap report flags patients where structured documentation is missing for what was clinically done.
