Practice policy and quality initiatives: using lean principles to improve screening mammography workflow.

The "lean" approach is a quality improvement method that focuses on maximizing activities that are valued by the customer and eliminating waste that impedes efficiency in the workplace. The unique philosophy of the lean approach encourages all members of the team to be directly involved in identifying areas of waste and generating solutions to eliminate them. When the breast imaging section at the authors' institution became part of a multispecialty breast care center, the result was escalating examination volumes, more complex cases, and overall increased demand on radiologists' time. After several unsuccessful attempts to improve the efficiency of the section, including evaluation by outside consultants, the decision was made to embark on a comprehensive quality improvement program using the lean approach. A team of radiologists, technologists, file room personnel, information technology (IT) representatives, and administrators from the breast imaging section met twice a month to learn about lean principles and how to apply them to screening mammography workflows. Sources of inefficiency (waste) were identified, and potential solutions were generated. Multiple trials were performed to test these solutions. Throughout the process, all team members were engaged in identifying the problems, suggesting solutions, and implementing change. Most of the tested solutions were successful and resulted in decreased patient wait times, improved efficiency for the technologists and radiologists, faster report turnaround, and advances in IT. In addition, staff members were introduced to the lean philosophy and became actively involved in improving their workplace, resulting in a more cohesive section.

Fabella fracture with CT imaging: a case report.

Fracture of the fabella is rare, may be easily overlooked, and can be a clinically important cause of posterolateral knee pain following traumatic injury or total knee arthroplasty. To date, nine case reports of fabella fracture with radiographic documentation have been reported in the literature. This report documents a 55-year-old male pedestrian who was struck by an automobile and presented with radiographs demonstrating depressed lateral tibial plateau and proximal fibula fractures. Computed tomography (CT) was performed for surgical planning and demonstrated the additional finding of a radiographically occult nondisplaced fabella fracture. To the best of our knowledge, this is the first case in which CT documentation of a fabella fracture is reported. Fracture of the fabella is a rare but important clinical entity which may be overlooked clinically and radiographically. Clinical information can provide a high index of suspicion, and when coupled with radiographic and CT findings, may lead to the correct diagnosis. CT imaging of the knee may confirm a suspected fabella fracture or may help detect a radiographically occult fracture.
