Time constraints and workload in the computed tomography department

Introduction

The escalating use of Computed Tomography (CT) has promoted higher radiographer workload, which can contribute to an increase of risks such as stress, job dissatisfaction, and potential health and safety issues. This study aimed to assess the impact of organizational, spatial, and temporal factors on procedures and workload in a CT unit, emphasizing patient safety and radiographer well-being. Addressing time pressure and optimizing workplace ergonomics are crucial in maintaining a balance between efficiency and quality, ensuring safe practices in modern medical imaging units.

Methods

The study was conducted in a Swiss university hospital CT unit and employed the Systems Engineering Initiative for Patient Safety (SEIPS) model to analyse the radiographers' workflow and time constrains. Observations and tasks’ analysis were used to collect data, including timing and location of tasks performed by radiographers.

Results

The radiographers’ workflow in the CT department is complex, involving multiple tasks. The entire process spans from 26 to 41 min but the Machine-Time (time spent inside the CT room) ranged from 10 to 16 min. The study identified inefficiencies in the workflow, namely in time spent on patient preparation and unsuited machine-time rate. The layout of the department, including limited space in the preparation area, contributing to ergonomic challenges for radiographers. Organizational factors, such as scheduling practices, also impacted workflow. The examination durations varied by type of scan and patient, leading to time pressure and potential safety concerns.

Conclusions

The study highlighted the need for more realistic time allocation in CT examinations to improve patient and radiographer safety. Recommendations include extending machine-time rate, adapting examination durations based on the type of CT, and assigning a dedicated radiographer for order review. It is also crucial improving the working environment to accommodate ergonomic needs. Addressing these issues can enhance the efficiency and safety of CT departments, benefiting both patients and radiographers.

Implications for Practice

Healthcare organizations should consider these study recommendations to improve the efficiency and safety of CT departments. By implementing the recommended changes, such as adjusting CT-time rate and optimizing working environments, radiographer satisfaction and patient safety can be increased, ultimately leading to safer and more effective CT services.
