Description

This measure provides a standardized method for monitoring the performance of diagnostic CT to discourage unnecessarily high radiation doses, a risk factor for cancer, while preserving image quality. It is expressed as a percentage of patients with CT exams that are out-of-range based on...

Rationale

Diagnostic imaging using CT occurs in more than a third of acute care hospitalizations in the U.S. (Vance, 2013) and greater than 90 million scans are performed annually in the U.S. (IMV, 2019). There is marked observed variation in the radiation doses used to perform these exams...

Clinical Recommendation Statement

The measure aligns with numerous evidence- and consensus-based clinical guidelines asking radiologists to track, optimize, and lower CT radiation doses, guidelines that have been written by the American College of Radiology (Kanal, 2017), cardiovascular imaging societies (Hirshfeld,...

Improvement Notation

Lower score indicates higher quality, and a decreased score over time indicates improvement

Definition

CT Dose and Image Quality Category: reflects the type of exam performed based on body region and clinical indication. Each CT Dose and Image Quality Category has a specific set of dose and image quality (global noise) thresholds.

Calculated CT Size-Adjusted Dose: reflects the total...

Guidance

This is an inverse measure; as such the higher the value the worse the performance.

The level of aggregation for this eCQM is the clinician. Parallel eCQMs report CT exams performed in inpatient and outpatient hospital settings and is aggregated on the facility level. A single CT exam may...

Initial Population

Patients aged 18 years and older at the start of the measurement period that have an eligible CT scan with Dose and Image Quality Category performed during the measurement period

Denominator

Equals Initial Population where an eligible CT scan has a Calculated Global Noise value and a Calculated CT Size-Adjusted Dose value

Denominator Exclusions

Patients with one or more eligible CT scans that has a CT Dose and Image Quality Category = full body

Numerator

Patients with one or more eligible CT scans with calculated CT Size-Adjusted Dose greater than or equal to a threshold specific to the CT Dose and Image Quality Category, or Calculated CT Global Noise value greater than or equal to a threshold specific to the CT Dose and Image Quality...
