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. This measure is expressed as a percentage of 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 et al., 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,...

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

The level of aggregation for this eCQM is the facility. A parallel eCQM measures CT exams aggregated at the level of the clinician or clinician group. A single CT exam may be simultaneously measured in both the Merit-based Incentive Payment System (MIPS) and one of the hospital reporting...

Initial Population

All CT scans in adults aged 18 years and older at the start of the measurement period that have a CT Dose and Image Quality Category and were performed during an inpatient hospitalization that ends during the measurement period

Denominator

Equals Initial Population with a CT Dose and Image Quality Category, a Calculated Global Noise value, and a Calculated CT Size-Adjusted Dose value

Denominator Exclusions

Denominator, where a CT scan with a CT Dose and Image Quality Category = full body

Numerator

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 Category
