National Pathology Quality Registry

The National Pathology Quality Registry (NPQR) is a national quality and benchmarking program led by ASCP. The registry captures data that measure adherence to clinical practice guideline recommendations, quality and performance standards, and appropriate utilization of laboratory testing.

Benefits of NPQR

NPQR helps laboratories optimize quality and performance in several key ways:

  • Monitoring appropriate utilization of laboratory testing
  • Improving pre-analytical processes
  • Optimizing turnaround time and critical value reporting
  • Establishing best practices through national and peer group comparisons
  • Assessing analytical and diagnostic accuracy

Quick Facts

Developed as a tool for pathologists and laboratory professionals to promote best practices within laboratory medicine. This tool will also benefit our clinical colleagues and ultimately improve patient care.

Designed with laboratory information system providers, the Registry supports integration with multiple LIS and includes quality and performance measures spanning several categories.

How to Participate

For more information and to inquire about participating, please contact Ali Brown, MD, FASCP, Chief Officer, Medical Quality, ASCP, and the ASCP NPQR team at NPQR@ascp.org.

Measures and Reporting 

The National Pathology Quality Registry is a member-driven initiative that will allow participants to collect and disseminate data critical to quality improvement in the laboratory. NPQR measures were created by pathologists and laboratory professionals to provide a trusted source for best practices and benchmarking. This interactive resource applies data aggregation and visualization tools to data from your lab’s LIS to help you develop projects to improve patient care and reduce costs.

As a tool focused on continuous quality improvement and business analytics, NPQR offers 30 NPQR-exclusive performance measures. NPQR measures were developed to apply to a wide variety of pathology specialties and practices.

Performance Measures

These measures are exclusive to NPQR and can be utilized for benchmarking and quality improvement practices in the laboratory. They are not used for CMS reporting to satisfy MIPS. Laboratories can choose to provide data on any or all of these measures, as they relate to their particular practice.
