Disinfection and sterilization are essential components of infection prevention and control in healthcare facilities and are directly associated with patient safety, quality of care, and the reduction of healthcare-associated infection risks. This article aims to review and synthesize international standards for disinfection and sterilization and to analyze their application in the context of healthcare facilities in Thailand. The review is based on key conceptual frameworks, including the Spaulding classification, guidelines issued by the Centers for Disease Control and Prevention (CDC), the Food and Drug Administration (FDA), the World Health Organization (WHO), and the Association for the Advancement of Medical Instrumentation (AAMI) standards ST79 and ST91. The article covers the principles of risk classification for medical devices, the selection of appropriate disinfection and sterilization methods based on device intended use, and factors that affect process effectiveness, including pre-cleaning, disinfectant concentration, contact time, temperature, material compatibility, quality assurance, traceability, and occupational safety. It also discusses practical challenges in reprocessing complex medical devices, such as flexible endoscopes and respiratory equipment. The synthesis indicates that the effectiveness of disinfection and sterilization processes depends not only on compliance with international standards but also on the integration of manufacturers’ instructions, device design characteristics, personnel competency, quality assurance systems, and the availability of institutional resources. These considerations are particularly important in Thailand, where healthcare facilities vary substantially in infrastructure and service capacity across different levels of care. In conclusion, the systematic application of international standards for disinfection and sterilization, adapted to the context of Thai healthcare facilities, can strengthen process quality, enhance patient and personnel safety, and reinforce infection prevention and control systems in the long term.
