Using Six Sigma to improve the film library

Area of Science:

• Healthcare Management
• Process Improvement
• Radiology Operations

Background:

• Film libraries are critical but often understaffed and underperforming components of radiology departments.
• Poor film library performance negatively impacts radiology and the entire institution.
• Previous success with Six Sigma for CT throughput improvement prompted its application to the film library.

Purpose of the Study:

• To dramatically improve the performance of a hospital's film library using Six Sigma techniques.
• To address operational inefficiencies and enhance service quality within the film library.
• To foster a better understanding of the film library's importance among staff and stakeholders.

Main Methods:

• Formed nine mini-project teams comprising library staff, radiology personnel, external stakeholders, and physicians.
• Teams developed process maps, collected baseline data, and recommended process modifications.
• A steering committee coordinated efforts, advised on implementation, and ensured alignment with project goals.

Main Results:

• Implemented recommendations led to improvements in quantitative performance metrics.
• Significant enhancement in employee morale was observed post-implementation.
• Ongoing data collection is in place to sustain improvements.

Conclusions:

• Six Sigma is effective for improving service-oriented operations like radiology film libraries.
• Manual data collection methods were necessary due to system limitations but presented challenges.
• Emphasizing accountability, providing constructive feedback, and educating staff on the library's institutional importance are key lessons learned.
