Multidisciplinary team training reduces the error rate of DXA image

Area of Science:

• Radiology and Imaging Science
• Bone Densitometry
• Medical Quality Improvement

Background:

• Poor quality dual-energy X-ray absorptiometry (DXA) images frequently challenge physicians, impacting osteoporosis treatment efficacy.
• Accurate DXA measurements are essential for diagnosing and managing osteoporosis.

Purpose of the Study:

• To evaluate the impact of multidisciplinary team training on the error rate of DXA images.
• To identify common sources of error in DXA measurements and assess the effectiveness of standardized protocols.

Main Methods:

• Development of hospital-specific standard operating procedures (SOPs) for DXA measurement.
• Multidisciplinary team training involving physicians and technologists on SOPs and image quality checks.
• Analysis of 637 DXA images (pre- and post-training) using defined error criteria for lumbar spine and proximal femur.

Main Results:

• Pre-training, common errors included inadequate bone mapping (lumbar spine) and incorrect region of interest (ROI) selection (femoral neck).
• Post-training, significant reductions in errors were observed: 23.2% for the lumbar spine and 9.0% for the proximal femur.
• Specific improvements included a 33.3% reduction in inadequate bone mapping and a 13.6% improvement in internal rotation for the proximal femur.

Conclusions:

• Establishing hospital-specific SOPs and implementing comprehensive team training effectively reduces DXA measurement error rates.
• This quality improvement initiative enhances the reliability of DXA scans, supporting better patient care for osteoporosis.
