GRID 2.0 and New Quality Measures

Launched in 2008 under the ACR National Radiology Data Registry (NRDR®) umbrella, the General Radiology Improvement Database (GRID) allows imaging facilities to compare their turnaround times (TATs), patient wait times, incident rates and other measures with their peers.

Now, 11 new quality measures recommended by ACR Metrics/Technical Expert Panels are available for reporting in the GRID registry. Seven of the new measures are also available for reporting in the ACR® Qualified Clinical Data Registry (QCDR) for the Merit-Based Incentive Payment System:

  • Interpretation of CT Pulmonary Angiography for Pulmonary Embolism
  • Incidental Coronary Artery Calcification Reported on Chest CT
  • Use of Structured Reporting in Prostate MRI
  • Surveillance Imaging for Liver Nodules <10mm in Patients at Risk for Hepatocellular Carcinoma
  • Use of Quantitative Criteria for Oncologic FDG PET Imaging
  • Use of Low Dose Cranial CT or MRI Examinations for Patients with Ventricular Shunts
  • Use of Low Dose CT Studies for Adults with Suspicion of Urolithiasis or Nephrolithiasis

The purpose of these new measures is largely to encourage appropriate follow-up imaging, use of standardized imaging findings documentation in the final report and use of low dose CT.

To support the new quality measures, GRID 2.0 now has 30 new fields for reporting. Access an overview of each new measure, along with a summary of the new data elements that must be submitted to GRID in order to calculate each measure.

Calling All Early Adopters

We’re looking for early adopters to submit data for the new GRID measures as soon as possible. Why? When implementing measures for use within quality improvement projects in NRDR, ACR is constantly analyzing data submissions to confirm the quality of the measure.

To maintain CMS approval of the seven new GRID/QCDR quality measures going forward, we must provide aggregated testing and performance data that demonstrates the scientific rigor, and importance of the measures, as well as performance data that shows a gap or variation in care exists. Data collected from early adopters is critical to that effort and also helps us establish performance benchmarks for each measure.
