The General Radiology Improvement Database (GRID) collects information about imaging facilities which is then aggregated to establish benchmarks for quality improvement. It allows facilities and physicians to compare turnaround times, patient wait times, incident rates and many other process and outcome measures with other facilities and practices of similar size and type.

GRID participation is certified as a Practice Quality Improvement (PQI) projects toward American Board of Radiology Part IV Maintenance of Certification (MOC) credit.

For physicians participating in CMS’s Merit-based Incentive System (MIPS), the GRID provides a means of comparing results of the various imaging measures included in MIPS.
