Time constraints and workload in the computed tomography department

Area of Science:

• Medical Imaging Technology
• Radiography Workflow Analysis
• Patient Safety in Diagnostic Imaging

Background:

• Increasing Computed Tomography (CT) use elevates radiographer workload, posing risks like stress and job dissatisfaction.
• This study addresses organizational, spatial, and temporal factors impacting CT procedures and radiographer well-being.
• Optimizing time pressure and workplace ergonomics is vital for balancing efficiency, quality, and safety in CT units.

Purpose of the Study:

• To assess the influence of organizational, spatial, and temporal factors on CT procedures and radiographer workload.
• To emphasize the impact on patient safety and radiographer well-being within a CT unit.
• To identify workflow inefficiencies and propose improvements for safer and more efficient CT services.

Main Methods:

• Utilized the Systems Engineering Initiative for Patient Safety (SEIPS) model in a Swiss university hospital CT unit.
• Employed direct observations and task analysis to gather data on radiographer workflow and time constraints.
• Collected data on the timing and location of tasks performed by radiographers during CT procedures.

Main Results:

• CT radiographer workflow is complex, with total procedure times ranging from 26 to 41 minutes (Machine-Time: 10-16 minutes).
• Identified workflow inefficiencies include excessive patient preparation time and suboptimal machine-time allocation.
• Departmental layout (limited preparation space) and organizational factors (scheduling) created ergonomic challenges and time pressure.

Conclusions:

• Realistic time allocation for CT examinations is crucial for enhancing both patient and radiographer safety.
• Recommendations include increasing machine-time rates, tailoring examination durations, and dedicated order review roles.
• Improving the physical working environment to meet ergonomic needs is essential for safer, more efficient CT services.
