As Medical device application in disease prevention, diagnosis or treatment is evolving to a greater extent; there is a need for regulation to monitor its quality, safety and efficacy. The present article attempts to study the medical device regulation available in eleven South-East Asian World Health Organization (WHO) member countries. The information searched from the available sources reveals that medical device regulation exists in seven countries. Most of the countries follow the International Organization for Standardization (ISO) 13485 for their quality standards in medical devices. Most countries also specified the time frame and authority to which adverse event is to be reported. Countries like India and Thailand have separate Adverse Event reporting forms for the medical device. The present study reveals that there is no separate web-based database for adverse event reporting of medical devices. Therefore, WHO South-East Asian Regulators Network (SEARN) under South East Regulatory Office (SERO) office may provide handholding support to these regions in developing a common software or tool for the management and analysis of signals arising from the adverse events.
