Objectives: To give guidance for review authors on formulating the question, the available data sources on adverse effects, and how to retrieve data for incorporation into a systematic review. This will include the development of optimal search techniques and discussion of the diverse formats of adverse effects data sources.

Description: Participants will receive a number of scenarios, and will then work together in small groups to plan a search strategy for a comprehensive evaluation of adverse effects. The scenarios will be drawn from real-life situations to cover a wide range of potential adverse effects.

At the end, groups will feedback on their search protocols, and any points raised will be discussed further. Examples from existing reviews will be provided by the facilitator, as well as tips and tricks to solve specific issues and give examples of sources of support and help available. The workshop will mostly focus on drug effects but the issues faced in identifying adverse effects for all types of interventions will be touched upon.
