Variability in Mammography Quality Assessment After Implementation of Enhancing Quality Using the Inspection Program...

Area of Science:

• Medical Imaging
• Radiology
• Quality Improvement

Background:

• Mammography quality is crucial for accurate breast cancer detection.
• The Enhancing Quality Using the Inspection Program (EQUIP) was implemented to standardize and improve mammography quality.
• Variability in quality assessment among radiologists can impact patient care.

Purpose of the Study:

• To analyze mammography quality and deficiencies identified by the EQUIP program.
• To assess the variability in quality assessment among subspecialized breast radiologists.
• To evaluate the effectiveness of EQUIP in identifying and addressing mammography quality issues.

Main Methods:

• Retrospective analysis of mammography data prospectively entered into automated reporting software after EQUIP implementation.
• Review of screening and diagnostic mammograms (digital mammography with tomosynthesis) by seven breast radiologists.
• Categorization of mammogram quality (excellent, good, adequate, problems found) and evaluation of deficiencies and corrective actions.

Main Results:

• Of 17,312 mammograms, 529 underwent EQUIP review, with 43 (8%) having identified problems.
• Insufficient tissue (53%) was the most common deficiency, followed by motion degradation (21%).
• Significant variability in quality assessment was observed among radiologists, including the lead interpreting physician.

Conclusions:

• Insufficient tissue is a primary mammography deficiency identified by EQUIP.
• Substantial variability exists in radiologists' quality assessments, underscoring the need for consistent application of standards.
• Continuous quality review through EQUIP provides opportunities for targeted feedback and improvement in mammography services.
