4.4 Surveillance Systems
According to the situation of traditional medicine in a particular country, governments may need to establish national surveillance systems at different levels of the health sector to monitor and evaluate any adverse effects of traditional medicine. Knowledgeable researchers and practitioners of traditional medicine should be consulted during the development of such systems.
The evaluation of adverse effects needs to be based on appropriate methods of determining causality. Such methods include instruments to determine adverse events experienced by target groups (patients and practitioners), prospective and retrospective studies to determine adverse effects in specific settings, and post-market surveillance of new devices (both herbal medicines and equipment used in traditional procedure-based therapy) where comprehensive evaluation of any adverse effect is documented.
