Examination of computer task exposures in radiologists: a work systems approach

Area of Science:

• Occupational Health
• Human-Computer Interaction
• Ergonomics

Background:

• Radiologists extensively use computers, particularly Picture Archiving and Communication Systems (PACS), for interpreting medical images.
• Prolonged use of pointing devices during these tasks is associated with a high prevalence of Musculoskeletal Disorders (MSDs).

Purpose of the Study:

• To analyze the total work system of radiologists.
• To identify and reduce physical exposures contributing to MSDs.
• To present Phase I results on task redesign and training for computer use.

Main Methods:

• Employed Cognitive Work Analysis and Participatory Ergonomics for work system analysis.
• Conducted ergonomic surveys and collected computer usage data (mouse and keyboard).

Main Results:

• Phase I focused on analyzing radiologists' tasks, computer use, and survey data.
• Initiated a redesign process for tasks and training programs.
• Identified specific computer use patterns contributing to physical strain.

Conclusions:

• Ergonomic interventions are crucial for mitigating MSDs in radiologists.
• Task and training redesign can effectively reduce physical exposures.
• Further research will build upon Phase I findings to implement and evaluate changes.
