Improving the efficiency and service of computed tomographic scanning

Area of Science:

• Healthcare Management
• Radiology Operations
• Health Services Research

Background:

• Operational efficiency in diagnostic imaging is crucial for healthcare systems.
• Computed tomography (CT) services face challenges with patient wait times and cost containment.
• Previous studies have explored various aspects of CT workflow but often lack comprehensive cost-benefit analysis.

Purpose of the Study:

• To quantify the impact of operational and management changes on service quality and costs in CT.
• To analyze the financial and operational outcomes following specific process improvements.
• To identify the key drivers of cost reduction and service enhancement in CT departments.

Main Methods:

• Conducted operational and financial analyses in 1988 and 1991.
• Implemented process flow and management changes between the analysis periods.
• Compared key performance indicators including backlog, cost per scan, and scan volume.

Main Results:

• CT scan backlog reduced from approximately 6 weeks to 1 week.
• Cost per scan decreased by 25%, while scan volume increased by 50%.
• Reduced throughput time contributed significantly to cost savings, alongside optimized scanner utilization and personnel allocation.

Conclusions:

• Simultaneous cost reduction and service quality improvement are achievable through strategic operations analysis and management in CT services.
• Operational changes demonstrated synergistic effects, yielding greater improvements than initially anticipated.
• Effective management strategies in CT operations can lead to counterintuitive but beneficial outcomes.
