A new concept in radiology QA in a large setting

Area of Science:

• Medical Imaging
• Radiologic Technology
• Quality Assurance

Background:

• Traditional film quality assessment relied on exam retakes, offering limited insight into specific technologist performance issues.
• Kaiser Permanente Northwest sought to enhance diagnostic imaging quality through a structured program for its radiologic technologists and radiologists.

Purpose of the Study:

• To establish a comprehensive quality assurance (QA) program for diagnostic film quality.
• To identify and address recurring issues in radiologic technologist performance.
• To foster professional development among technologists through targeted feedback and education.

Main Methods:

• Development of a standardized diagnostic image quality benchmark by radiologists and QA staff.
• Random selection and review of 50 exams per technologist every two months by QA technologists.
• Utilization of quality control (QC) slips by radiologists during exam reading for direct technologist feedback.
• Provision of one-on-one assistance, classes, and demonstrations by QA technologists.

Main Results:

• The QA program identifies recurring technologist performance issues by evaluating individual views rather than entire exams.
• Direct communication and feedback loops are established between radiologists and technologists via QC slips.
• Supervisors enforce performance standards based on QA feedback, with an appeals process available.

Conclusions:

• The implemented QA program effectively maintains diagnostic image quality to meet both hospital radiologists' and industry customer requirements.
• The program serves as a valuable tool for the ongoing professional development of radiologic technologists.
• A collaborative approach between QA technologists and radiologists is crucial for successful image quality improvement.
