Development of a Participation of Occupational Health Risk Management Model for Personal in the Central Sterile Supply Department (CSSD), Mahasarakham Hospital

Abstract

Objective : To develop and evaluate a participatory occupational health risk management model for personnel in the Central Sterile Supply Department (CSSD) at Mahasarakham Hospital.

Methods : This study employed Participatory Action Research (PAR). The target population, selected through purposive sampling, consisted of two groups: 66 participants in total, including CSSD personnel (model developers) and members of the Occupational Safety, Health, and Environment (OSHE) Committee (model users). The study was conducted from April to September 2025. Research instruments included health and work environment risk assessment forms and occupational hazard exposure questionnaires. Work environment monitoring was performed using industrial hygiene instruments. Data were analyzed using descriptive statistics, including percentage, mean, and standard deviation, and comparative analysis was conducted using the Wilcoxon signed-rank test.

Results : The primary target group consisted of 46 participants with an equal gender distribution. The majority (47.8%) were aged between 45–59 years (X=44.3, SD=8.9) and 39.1% had 5–10 years of work experience in the CSSD (X=9.2, SD=6.1). Initial assessments identified chemical hazards at an unacceptable risk level. The developed MSKH Model comprises four key components: Monitoring (risk surveillance and follow-up), Survey (hazard identification), Knowledge (capacity building), and Hazard Control. Worker participation in risk control focused on reviewing and establishing Standard Operating Procedures (SOPs) for safety, improving the work environment, and conducting safety training. Post-training knowledge scores were significantly higher than pre-training scores (p-value < 0.001). Implementation of the model successfully reduced chemical risks to a moderate level. A key success factor was the active participation of frontline personnel in managing and controlling occupational health risks.

 Conclusion : The occupational health risk management model comprises monitoring, hazard identification, knowledge, and hazard control. By engaging workers in control activities tailored to identified issues, the model effectively reduced occupational health risk levels among CSSD personnel at Mahasarakham Hospital.
