Risk Analysis of Patient Transport Personnel Using ISO 45001:2018 in Vajira Hospital, Thailand.

Purpose: This study aimed to evaluate occupational health and safety risks among patient transport personnel at Vajira Hospital, Thailand, using the ISO 45001:2018 Occupational Health and Safety Management System (OHSMS). The goal was to identify hazards, quantify risk levels, and propose targeted corrective measures to enhance workplace safety. Patients and Methods: Data were collected from 60 patient transport personnel and their supervisors using in-person, semi-structured interviews. Task-related hazards were identified through standardized checklists aligned with ISO 45001:2018. Descriptive statistics (frequencies, percentages, mean values) were applied to summarize participant characteristics and risk levels. Results: Among 21 assessed work activities: 2 activities were categorized as very high risk (ergonomic hazards). 12 activities as high risk. 6 activities as medium risk. 1 activity as low risk. Key hazards included repetitive lifting, awkward postures, and potential exposure to infectious agents. ISO 45001:2018 clauses 6.1.2 (Hazard Identification and Risk Assessment) and 8.1 (Operational Planning and Control) were most relevant for these high-risk activities. Conclusion: The study identifies urgent needs for ergonomic interventions, staff training, and procedural adjustments to reduce high-risk activities. Implementing ISO 45001:2018 systematically can improve hazard control and promote a safer working environment for patient transport personnel in hospital settings.
