放射線科における人間工学的実践の最適化：ワークステーション基準とスタッフの幸福度に関するクローズドループ監査

Radiology professionals are increasingly exposed to prolonged computer use, placing them at risk for musculoskeletal, ocular, and postural health issues. Studies report that up to 88.9% of radiologists experience work-related musculoskeletal disorders, while 36-50% report ocular strain or visual fatigue. Optimising workstation ergonomics is therefore critical for maintaining both staff wellbeing and diagnostic accuracy.

To assess compliance with the Royal College of Radiologists (RCR) ergonomic workstation standards among radiology staff and evaluate improvements following targeted interventions between audit cycles.

A two-cycle electronic questionnaire audit was carried out, with 46 responses in total - 25 in 2023 and 21 in 2024 - from consultant radiologists and reporting radiographers across two hospital sites. Audit standards were based on the RCR ergonomic guidance - "Correct Use of Reporting Workstation." The questionnaire was developed from this publicly available RCR standard and adapted for local use. Data were analysed using descriptive statistical methods to summarise and compare compliance between the two audit cycles.

Overall, 100% (25/25 in 2023 and 21/21 in 2024) had access to voice recognition in both cycles, and there was an increase from 9/25 (36%) to 14/21 (67%) in terms of variable lighting at workstations. Eye test compliance declined in the second cycle of the audit, and only 10/21 (48%) reported taking regular breaks, which improved from 9/25 (36%) since the first cycle. Moreover, awareness of ergonomic guidelines improved, but conformance remained low.

While improvements were noted in some domains, gaps remain in key areas such as break-taking and regular eye tests. Sustained efforts are required to support ergonomic practice adoption and reduce staff health risks.
